0.1.0 2007-03-09 Gregory Nutt * Initial Release * Support for Linux user mode simulation and TI TMS320C5471 (Arm7) provided 0.1.1 2007-03-14 Gregory Nutt * Corrected an error in interrupt level context switching for C5471 * Added fgets() and gets() logic; verified c5471 console read. * Corrected error in reading from the C5471 serial port: Improper use of semaphore can cause deadlock. * Fixed an error in the memory cleanup: The idle task cannot take semaphores (because it must always be ready to run). * Tasks can now accept a configurable maximum number of input parameters (argc) * _task_init() was divided into separate functions that require fewer parameters. This was necessary to keep the stack usage down for the 8051/2 (which has only 256 bytes of stack). * Attempts to use C5471 console from interrupt handlers can cause errors. Added a special path for this case. * Refuse calls to sem_wait and sem_trywait from interrupt handlers. This was happening because interrupt handlers were calling printf-like functions. * Added strtok() and strtok_r() * Added a simple shell called nsh (see examples/nsh). * Platform support for 8052 is complete but not stable when the timer interrupt is enabled. Seems to be an issue when SP enters indirect address space. * Documentation updates 0.1.2 2007-03-19 Gregory Nutt * Add dirent.h, opendir(), readdir(), closedir(), etc. * Add strerror() * Added 'ls' command to nsh * Added C5471 watchdog driver * Fixed another bug where free() is called from IDLE task. Can't do this; the caller must be able to wait for access to memory. * Fixed bugs associated with debug output: Cannot do dbg() in middle of context switch logic. because it may require use of semaphores and cause additional context switches. lldbg() is safe. * Interrupt must be disabled throughout all context switches. * Separated C5471 serial driver; a shareable part is in drivers/. ; the C5471 specific part is in arch/C5471. serial.h defines the interface. * Fixed mq_receive() and mq_send(): bad memcpy() * Fixed C5471 signal deliver logic: use of dbg() and other actions by use signal handler can alter errno. need to protect errno during signal handling. * Fixed uninitialized variable in filesystem that could cause various problems * Added a test for roundrobin scheduler. 0.2.1 2007-03-22 Gregory Nutt * Fix error in handing signed decimal in vsprintf(). * Major restructuring of header files to get closer to POSIX compliance. * Eliminate compilation warnings that crept into recent check-ins * Add kill() * Added support for POSIX timers * Some Documentation updates * Added support for the Neuros OSD / DM320 0.2.2 2007-03-26 Gregory Nutt * Created the configs/ directory; separated board configuration from processor architecture logic * Add memory leak detection test to examples/ostest * Corrected memory leak in OS pthread join logic * Corrected memory leaks in examples/ostest due to failures to join or detach from pthreads. * Added pthread_once(), pthread_kill(), pthread_sigmask() * Added pthread_barrierattr_*() APIs * Added pthread_barrier_init(), pthread_barrier_destroy(), and pthread_barrier_wait(); * Added pthread barrier test * Added protection so that errno cannot be modified from interrupt handling. * sched_setparam(), sched_setscheduler() now correctly set errno; pthread_setscheduler() now returns the correct errno. * Added pthread_setschedprio(). * Added directories to hold board-specific header files * Added directories to hold board-specific drivers 0.2.3 2007-03-29 Gregory Nutt * mq_receive and mq_send now return errno's appropriately * mq_receive and mq_send are now correctly awakened by signals. * Fixed an unmatched sched_lock/unlock pair in task_delete(). * sched_lock must be called in _exit() because operation of task_delete() can cause pending tasks to be merged and a context switch to occur. * Added mq_timedreceive() and mq_timedsend() * signal mask is now inherited by both child tasks and threads. * Improved sharebility of stdout among pthreads (only). Nothing was broken, but by moving the mutual exclusion logic to a higher level, the printf output is more readable. * Fixed a bug in file system cleanup: A list was being deleted before the buffers contained in the list. * Fixed a bug in the wait-for-message-queue-not-empty logic. * Added a test of timed mqueue operations; detected and corrected some mqueue errors. * Identified and corrected a race condition associated with pthread_join. In the failure condition, memory was being deallocated while still in use. 0.2.4 2007-04-28 Gregory Nutt * Verified c5471 build under Cygwin on WinXP * Makesystem changes to better support different SoCs. * Made arch/c5471/include and arch/dm320/include identical in preparation for merging into arch/arm * Logic from arch/c5471 and arch/dm320 combined into arch/arm. arch/c5471 and arch/dm320 are deprecated and will be removed when the new c5471 and dm320 logic is verified. 0.2.5 2007-05-19 Gregory Nutt * Corrected some build/configuration issues introduced with the last release. * Added support for the NXP 214x processor on the mcu123.com lpc214x development board (untested) * Added support for block devices. * Simulated target now exports a VFAT filesystem * Begin support for VFAT filesystem (missing functionality) * Added mount() and umount() * Fix bug in memcmp return value * Fix errors in timeslice calculation (several places) * Added missing irqrestore() in timer_deleteall(). * close() was not closing the underlying device. * Added fsync() * Added strspn() and strcspn() 0.2.6 2007-05-26 Gregory Nutt * Added unlink(), mkdir(), rmdir(), and rename() * Fixed several serious FAT errors with oflags handling (&& instead of &) * Added FAT support for unlink(), mkdir(), rmdir(), and rename * Added FAT support for opendir(), closedir(), readdir(), seekdir(), telldir(), rewindir(). * Fixed ARM compilation errors introduced in 0.2.5 (that is what I get for only testing on the simulation). 0.2.7 2007-06-09 Gregory Nutt * Added stat() to fs layer and to FAT * Fixed reference counting errors associated with mounted filesystems * Added fat_getattrib() and fat_setattrib() * Added statfs() to fs layer and to FAT * Correct file name extension in tools/zipme.sh * Fix error in dependencies in 8051/2 Makefile * sched/Makefile: Don't build sleep() or usleep() if signals are disabled * sched/sched_setparam.c: Remove redundant disabling of interrupts * sched/usleep.c: Fixed nsec calculation * lib/lib_strcspn.c: Function incorrectly named strspn(). * examples/ostest/main.c: Errors in SDCC version of a memcpy() call * examples/ostest/sighand.c: Don't call fflush() if streams are disabled * include/limits.h, include/time.h, sched/clock_internal.h: A support for using selectable system timer frequency. * Fixed error in mountpoint related conditional compilation introduced in 0.2.5 * Restructured some Makefiles to better handle enabling and disabling NuttX features without having so much conditional compilation in the source files. * tools/mkconfig.c: No longer depends on asprintf() and _GNU_SOURCE and so should now build in non-GNU, non-GLIBC environments. * include/nuttx/compiler.h: Fix for using SDCC with the Z80. * include/assert.h & arch/pjrc-8051/src/up_assert.c: SDCC does support __FILE__and __LINE__ (not tested) * examples/ostest/barrier.c: Don't call usleep() when signals are disabled. 0.2.8 2007-07-02 Gregory Nutt * tools/Makefile.mkconfig: Under Cygwin, executable has a different name * tools/mkdeps.sh & arch/arm/src/Makefile: Corrected a problem makeing dependencies * tools/zipme.sh: Force directory name to be nuttx-xx.yy.zz * fs/fs_opendir.c: Correct errors in semaphore usage that can cause deadlock. * lib/lib_getopt.c: Added getopt() support * examples/nsh/: NSH now supports cat, mount, umount, and mkdir. ls supports -l -s, and -R * Added basic OS support to manage environment variables: environment storage, cloning on task creation, sharing on pthread creation, destruction on thread/task exit. * Add environment variables APIs: environ, getenv, putenv, clearenv, setenv, unsetenv * Correct an error in realloc() when the block is extended "down" in memory. In this case, the old memory contents need to be copied to the new location and an allocated bit was not being set. * examples/ostest/: Added an environment variable test. * examples/nsh/: Break into several files. * lib/: Added strrchr, basename, dirname * examples/nsh/: Add cp, rm, rmdir, set, unset commands. echo will now print environment variables. 0.3.0 2007-11-06 Gregory Nutt * Imported uIP into the tree (see http://www.sics.se/~adam/uip/index.php/Main_Page) * Adding socket(), bind(), connect() * Added snprintf() * Added send() and sendto(); integrate write() and close() with socket descriptors. * Added recv() and recvfrom(). * Added getsockopt() and setsockopt() * Documentation updated to address socket interfaces. * Implemented receive timeouts via setsockopt(SO_RCVTIMEO). * Provide support for multiple network devices * Implement socket ioctl() calls to set addresses * Added listen() and accept() * Added DM90x0 Ethernet driver * ARP timer is now built into the network layer * Basic client functionality verified: TCP socket(), bind(), connect(), recv(), send(). 0.3.1 2007-11-19 Gregory Nutt * Separated net/uip/uip.c into several functions in several files. * Corrected a TCP problem where packets were dropped because there was no recv() in place but the packet was being ACKed. There are still TCP recv buffering issues, but this is part of a larger buffering issue. * Basic server functionality verified: TCP listen(), accept() * Fix DM90x0 driver problem that caused TX overruns * Add strncmp() * Added TCP/IP read-ahead buffer to minimize failed ACKs and packet loss. 0.3.2 2007-11-23 Gregory Nutt * Add strcat() and strncat() * Integrated uIP micro webserver * Corrected a serious bug in TCP queue management * Fix leak in socket close logic * Add TX notification to driver so that it can respond faster to the availability of TX data. * Moved urgent data info into device structure. * TCP and ICMP protocols can now be disabled. * Added UDP test in examples/udp * Verified/debugged UDP socket(), bind(), sendto() and recvfrom() logic using examples/udp * recvfrom() and accept() now correctly return the remote address. * Fixed computation error in ntohl(). 0.3.3 2007-11-28 Gregory Nutt * Removed unused uIP files * sched/, mm/, and net/ subsystem debug can not be selectively enabled/disabled * Correct socket close logic: needs to disconnect TCP socket on close * uIP webserver now seems to be fully functional * fs/ and lib/ subystem debug can not be selectively enabled/disabled * Added vsnprintf * Integrated uIP telnetd * Add missing logic to read-ahead buffer logic * examples/nettest uses larger buffers * Improved ACK handling in send() to better handler deferred acknowledgements and polling intervals.

Affects all architectures. 0.3.8 2008-02-10 Gregory Nutt * Added a test case to verify the Pascal P-Code interpreter * Added /dev/zero * 'errno' is now defined to be *get_errno_ptr() with no name conflicts * Added lseek() and fseek() * Integrated Pascal interpreter test case on the simulation platform. Needs pascal-0.1.1. * Add Pascal test case on the z16f platform. Needs pascal-0.1.2 (does not yet work due to some tool issues). * C buffered I/O fixes: - Fix fflush() return value, - Add correct fflush behavior when the FILE argument is null. - Add logic to a correctly handle read/write access on the same FILE - fseek() flushes read/write data when before moving the file pointer - When read data is flushed, reposition the file pointer to account for buffered, but unread data * Pascal P-Code files are now standardized to big-endian for portability * Fix a build problem with z80 and SDCC 2.7.0 (format of a map file changed) (see bug 1887170) * Pascal P-Code runtime now compiles with the SDCC toolchain. * Added a generic CAN driver. This driver is untested as of this writing. * Corrected DM320 UART configuration problem 0.3.9 2008-03-09 Gregory Nutt * Began adding support for the ZiLOG Z8Encore! microcontroller for the Z8Encore000ZCO development board and the Z8F6403 part. * Fix broken 'clean' target on z80sim configurations * Re-structure arch/z80 to provide support for all ZiLOG 8-bit microcontrollers (ez8 in particular for now). * Add support for TRS80-Model 3 based on the xtrs emulation (http://www.tim-mann.org/xtrs.html) Per patch from Jacques Pelletier. * In all shell scripts, change #!/bin/sh to #!/bin/bash to resolve problems in Ubuntu where /bin/sh is a link to dash. * Z8Encore! port verified on ZDS-II instruction set/chip simulator. 0.3.10 2008-05-15 Gregory Nutt * Add support for the ZiLOG EZ80Acclaim microcontrooler (EZ80F91 chip). * Add configuration for the ZiLOG z8f64200100kit development kit, Z8F6423 part. * Add configuration for the ZiLOG ez80f0910200kitg development kit, EZ80F091 part. * Correct critical list handling errors in task shutdown logic: One in timer deletion logic (timer_delete.c) and one in stream logic (lib_init.c) reported by kwonsk. 0.3.11 2008-06-01 Gregory Nutt * Add support for recursive mutexes. * Eliminate a memory leak: contained watchdog instance was not being deleted with a POSIX timer was deleted reported by kwonsk. * Eliminate a deadlock condition in opendir() reported by kwonsk. * Fix several FAT filesystem problems reported by kwonsk (Changes not yet verified). * Host simulator no longer uses Linux system calls directly; Now works with Cygwin. * Fix an error that occurs when a POSIX timer is deleted by the timer signal handler. * Add logic to allow the examples/ostest to be run repetitively as an endurance test. * Add a ramdisk block driver 0.3.12 2008-08-10 Gregory Nutt * Improved solution to POSIX timer lifetime controls bug fixed in 0.3.11. * Add test for recursive mutexes * Correct bug in recursive mutex logic * Add mkfifo() * Add pipe() and test for both pipes and fifos * Attempts to open a FIFO will now block until there is at least one writer * Add test/Fixed errors in FIFO reader/writer interlocks * Removed limitation: task_create() was only dup'ing 3 file descriptors (now dups all open file descriptors). * Added a test for redirection of stdio through pipes * Fixed error in dup and dup2: Must call open/close methods in fs/driver so that driver can correctly maintain open reference counts. * Same issue on closing file descriptors in exit() * Fixed in error in stdio flush logic. Needed ssize_t vs size_t for error check. * Moved all FAT related files from fs to fs/fat * Implemented mkfatfs(), a non-standard API to create a FAT filesystem on a block device (not yet tested). * Added a test for mkfatfs() on a RAM disk in examples/mount and verified basic mkfatfs functionality for FAT12. 0.3.13 2008-09-01 Gregory Nutt * NSH: Added mkfatfs, mkfifo, sleep, usleep and nice commands * Fixed problem with console input in Cygwin-based simulator; NSH now works with simulator. * NSH will now execute commands in background * sched_get_priority_max/min returned error on SCHED_RR * Removed duplicate getenv() implementation in /lib * Correct detection of End-of-File in fgets * NSH: Implemented sh and crude script handler * Fix prototype of read() and write(). Need to use ssize_t and size_t, not int and unsigned int. * NSH now supports redirection of command output * NSH can now use both telnet and serial front ends together * NSH: $variable can be used for any command value * Fixed an error in opendir() that could cause an assertion to fail inappropriately. * Correct an error in the FAT that caused files opened for writing with O_APPEND to fail. The file was not being properly positioned to the end of the file in that case. * NSH now supports last exit status $? * NSH now supports if-then[-else]-fi construct * NSH now supports comments beginning with '#' * NSH now supports commands to inspect and modify memory * NSH cat command now supports multiple files on command line * Add chdir() and getcwd() * Fix error in getopt() when called with argc==1 * Fix error in stat() when used on the root directory * NSH: Add cd and pwd commands and current working directory to all NSH commands that refer to paths. * Fix errors and warnings introduced into Linux sim build because of recent Cygwin-based sim changes * NSH: Add mem command to display heap usage * Added telnet NSH configuration for Neuros OSD. * Basic integration of concurrent telnet/serial NSH functional on Neuros OSD. * Fixed a critical bug that affects the way that environment variables are shared amongst pthreads. * uIP port enhance to support multi-threaded, concurrent socket access. So, for example, one thread can be reading from a socket while another is writing to the socket. 0.3.14 2008-09-08 Gregory Nutt * FAT FS now uses position variable in struct file. This simplifies operations like ftell(). * fseek() needs to discard bytes buffered by ungetc(). * Corrected ftell() return value. * Added fsetpos() and fgetpos(). * NSH: Now supports 'test' and '[' commands * Correct error in send() timeout logic. * Correct error in multi-threaded socket handling in send() and sendto(). Outgoing data could overwrite incoming data. * Add support to uIP for application access to ICMP protocol stacks; Add ping request logic. * NSH: Add ping command * Correct IP checksum calculation in ICMP and UDP message send logic. * NSH: Created an HTML document and a more detailed README file describing NSH. * Added basic TFTP client logic (netutils/tftpc). * NSH: Add get and put commands to support TFTP get and put operations. * NSH: Added a mkrd command that will create a RAMDISK that can be formatted and mounted. * Corrected a critical bug that prevent recvfrom from receiving packets from any remote UDP port. * NSH: Add hexadecimal dump command (xd) * Fixed several critical bugs with regard to fat reading and writing and FAT12 accesses. Basically the FAT FS only worked with my tiny test files and test cases. A lot of stronger FAT tested is needed!! * Fixed another FAT bug in implementation of FAT lseek; this prohibit correct random access to large files. 0.3.15 2008-09-20 Gregory Nutt * Added support for ROMFS filesystem. * Added a simple test the ROMFS filesystem (examples/romfs) * NSH: Use ROMFS to provide an option for a start-up script at /etc/init.d/rcS * Add definition of BIOC_XIPBASE ioctl and implement in RAM disk block driver. This is a low level requirement for eXecute In Place (XIP) support. * Add a FIOC_MMAP to perform memory mapping of a file and implemented the ioctl command in the ROMFS filesystem. This is a requirement for eXecute In Place (XIP) support. * Add mmap() API with restricted capability (only for XIP support) * Extend ROMFS test at /examples/romfs to verify mmap() and XIP support. * Add support for Intel Hex format output using objcopy * Completed the basic port of the NXP LPC2148 on the mcu123.com board. The basic port includes successful booting, timer interrupts, serial console, succesfully passing the examples/ostest, and a NuttShell (NSH) configuration. * ARM architectures now support drivers/lowconsole.c 0.3.16 2008-10-10 Gregory Nutt * Added header files defining a common USB device controller architecture * Added USB device side driver for the LPC214x * Correct the frequency of system timer interrupts in the NXP LPC214x port (off by 20x in nuttx-0.3.15) * Add an option to set aside a separate stack for interrupt handling (ARM only). This is useful when memory is constrained, there are multiple tasks, and the interrupt stack requirement is high (as when USB is enabled). * Added USB serial class device side driver (emulates Prolific PL2303 serial-to-USB adaptor) * Add LPC214x USB serial configuration; Add examples/usbserial test * Added USB device side driver for the DM320 (untested at initial release) * Fixed an error in a previous (post 0.3.15) check-in that broke the LPC214x system timer. * Fixed serial driver bugs related to (1) open counts and (2) recognizing O_NONBLOCK on read. * Fixed an error in read(); it was not setting the errno on errors returned from the driver. 0.3.17 2008-10-28 Gregory Nutt * Incorporate patch "[2164503] nuttx-0.3.16 does not build for ARM with USB disabled" * Reduced the amount of memory reserved for USB serial control requests. It was unnecessarily large. * Added LPC214x SPI1 driver to interface with MMC on mcu123.com board. * Added a simple SPI-based MMC/SD block driver * NSH: Add LPC214x-specific support to NSH; NSH now mounts any SD cards in the slot. * FAT: Fix access to unaligned 32-bit values in partion table (start sector & size) * Fixed a problem with a un-initialized variable in the USB serial driver. * Added USB storage NXP LPC214x configuration * Added a test for USB storage under examples/usbstorage * Fixed a bug in the LPC214x USB driver: It was not properly clearing a HALTed endpoints (other than EP) on receipt of CLEAR FEATURES request. * Added USB storage class device side driver (BBB) * Fixed a bug in the LPC214x USB driver: It was not properly handling request buffers larger then the endpoint's max packet (DM320 driver also fixed, untested) * Added logic to the USB device interface: A bit is needed to force the driver to to terminate an IN transfer with a short packet (zero-length if necessary). * Fix an error in the NXP LPC214x USB device driver that was causing corruption of the request queue (M320 driver also fixed, untested) * Correct another error in the NXP LPC214x USB device driver that caused read failures when the request buffer size was larger than maxpacket. * Numerous corrections/extensions to the USB tracing logic included in 0.3.16 (but not integrated until 0.3.17) * Fixed another bug in the NXP LPC214x USB device driver: After a stalled endpoint is resumed (view CLEAR FEATURE), we must restart the IN (outgoing) queue. 0.3.18 2008-11-16 Gregory Nutt * Added port for the STMicro STR71x processor and configuration for the Olimex STR-P711 board (STR71x testing is stalled because I have been unable to get OpenOCD to communicate with my JTAG wiggler on Linux). * Fix race condition workaround delay in LPC214X SPI logic. This was also the cause of the very bad MMC/SD performance. * Began port of the Hitachi SH-1 using the SH-1/US7032EVB1 board * Re-built all configurations that use SDCC and Zilog toolchains to make sure they still build (they didn't, but they do now). * Fixed several erroneous "list empty" checks in the CAN driver. * Hitachi SH-1 passes (reduced) examples/ostest; the examples/nsh test still fails. There are remaining instabilities that make the port un-usable. The nature of these is not understood; the behavior is that certain SH-1 instructions stop working as advertised. This could be a silicon problem, some pipeline issue that is not handled properly by the gcc 3.4.5 toolchain (which has very limit SH-1 support to begin with), or perhaps with the CMON debugger. At any rate, I have exhausted all of the energy that I am willing to put into this cool old processor for the time being. * Renamed configuration item CONFIG_PROC_STACK_SIZE as CONFIG_IDLETHREAD_STACKSIZE: It now only controls the size of the stack for the IDLE thread. Added CONFIG_USERMAIN_STACKSIZE: This is the size of stack used with the user_start() thread is created. The two stacks no longer have to be the same. * Add a loop device that converts a file into a block device. * Each NSH command can not be disabled through a configuration setting. All of these settings make the configuration of NSH potentially complex but also allow it to squeeze into very small memory footprints. * Added a block to character (BCH) driver. This is kind of the reverse of the loop device; it allows you access a block device like a character device. * Added strcasecmp() and strncasecmp() * NSH: Added the 'dd' command * NSH: Added the 'losetup' command * Fixed a FAT bug: After recent changes, it would mount a (invalid) FAT file system even if the medium is not formatted! * Corrected two important errors in FAT lseek implementation: (1) the sectors-per-cluster value was being reset to "1" and (2) important lseek logic was omitted when the seek position was zero. * Fixed a bug in getopt(). It would fail if on certain combinations of terminal argument types. 0.3.19 2008-11-26 Gregory Nutt * Add poll() and select() APIs (in the initial check-in, these work only with character devices) * Add poll() methods to /dev/null, /dev/zero, pipes, fifos, and serial drivers. * Add examples/poll for testing poll() and select() * Fix hostile behavior of getc, fgetc, getchar, etc.: the serial driver was waiting for a full buffer of read data before return. This means that getc would stall when it needed to refill the input buffer. The old behavior (read full blocks) might be useful in other contexts, so it is still available within the driver as a configuration option. * Implement poll() and select() support for TCP/IP sockets * Fixed an important bug in the TCP/IP buffering logic. When TCP/IP read-ahead is enabled and not recv() is in-place when a TCP/IP packet is received, the packet is placed into a read-ahead buffer. However, the old contents of the read-ahead buffer were not being cleared and old data would contaminate the newly received buffer. * Implemented support for connection backlog. The size of the backlog is specified by the second argument of the standard listen() API. Hooks are provided to support poll()/select() waiting for connections, with a subsequent call to accept() to use the backlogged connection. * Fixed a minor bug in accept(). It should allow the address and addresslen values to be NULL * Added first-cut definition for a framebuffer interface (and simulated framebuffer for testing purposes only) * Added fixed precision math support * Added some color converson routines into what may become a real graphics library someday. * Added a framebuffer driver for the DM320 (untested on initial check-in) * Network: Add support for outgoing multicast addresses * Added some rasterizers to the graphics library 0.4.0 2008-12-06 Gregory Nutt * Initial release of a tiny windowing system for NuttX * Add fixed precision sin() and cos() (not well tested at initial check-in) * Add an X11-based simulated framebuffer driver * The simulated target now has an option (CONFIG_SIM_WALLTIME) that will let the simulation run in more-or-less realtime. * Added more extensive window support: frames, toolbars, etc. * Added support for bitmap fonts * Integrated the new font support with a font test in examples/nx * Add documentation for NX graphics subsystem 0.4.1 2009-02-06 Gregory Nutt * Added board support for the ZiLog eZ80Acclaim! ez80f910200zco Development Kit. * Fixed several compilation errors in fixed precision math library when built against toolchains that do not support 64-bit type 'long long'. * Fix errors in some function prototypes in dirent.h * Add eZ80F91 EMAC driver * Fix recvfrom() compilation error: only noted under ZDS * Updated all ARM Make.def files to work with gcc 2.4.2 (However, there are still some build issues associated with that toolchain in use of arm-elf-objcopy -- see the TODO.txt list for details) * Fix problems with Z16F and eZ80 compilation introduced with recent changes. 0.4.2 2009-02-28 Gregory Nutt * M16C: Add support for the Renesas M16C MCU and the SKP16C26 StarterKit. However, the target cannot be built because the GNU m16c-elf-ld link fails with the following message: m32c-elf-ld: BFD (GNU Binutils) 2.19 assertion fail /home/Owner/projects/nuttx/buildroot/toolchain_build_m32c/binutils-2.19/bfd/elf32-m32c.c:482 Where the reference line is: /* If the symbol is out of range for a 16-bit address, we must have allocated a plt entry. */ BFD_ASSERT (*plt_offset != (bfd_vma) -1); No workaround is known at this time. This is a show stopper for M16C. * eZ80Acclaim!: Fix interrupt vectors positioning; they were being positioned wrong by 64 bytes (Kevin Franzen). * eZ80Acclaim!: Corrected some stack handling errors during interrupt handling context save and restore (Kevin Franzen). * eZ80Acclaim!: Corrected vector initializeation logic (Kevin Franzen). * eZ80Acclaim!: Corrected overflow problem in the calculation of UART baud rate divisor, the system timer divisor, and the EMAC poll timer. * eZ80Acclaim!: Fixed GPIO pin configuration get serial output * eZ80Acclaim!: Correct stack overflow in ostest example configuration * eZ80Acclaim!: Fixed restoration of interrupts state on interrupt level context swith. 0.4.3 2009-03-04 Gregory Nutt * z8Encore! and eZ80Acclaim!: Fixed the serial driver initialization sequence * eZ80Acclaim!: Fixed error in vector table: Missing space set aside for the "unused" vectors. As a result, all vectors above timer4 were skewed. * eZ80Acclaim!: Fixed logic error in UART interrupt handler. * Many fixes in FAT file system and in NSH for correct compilation with ZDS-II * eZ80Acclaim!: Added and verified a NuttShell (NSH) configuration. * eZ80Acclaim!: Correct endian-ness; defconfig files said BIG endian. * Restructured parts of the uIP port for correct compilation with ZDS-II * eZ80Acclaim!: Complete basic integration of the eZ80F91 EMAC driver. The driver is basically functional and should mature prior to the 0.4.3 release. * Implemented priority inheritance logic for POSIX semaphores. Because the pthread mutexes are built on semaphores, they will have this property as well. 0.4.4 2009-03-29 Gregory Nutt * examples/nsh: A debug option was left on that can (and does) cause infinite loops and stack overflows. * net/uip: Correct calculation of checksum on ICMP ping response. * examples/dchpd: Added a tiny DHCP server example * net/uip: Correct UDP bind behavior. It should select a valid port number if it receives a port number of zero. * netutils/dhcpd: correct for ZDS compiler. Fix issue with re-use of a port number. Fixed a number of broadcast-related problems. * eZ80Acclaim!: Add a tiny webserver configuration * eZ80Acclaim!: Fixed an important bug in the EMAC Tx timeout logic. It was always timing out when the load was heavy and worse, for some reason, resetting the Tx function caused unexpected registers to be reset in the Rcv function was well. * Z80: Patch incorported: "[2696648] Z80: interrupt flag stored in parity bit" (submitted by JPelletier). The is the same fix that was needed for the eZ80 and fixed in 0.4.2. * netutils: Added logic to support a simple wget() function * examples/wget: Added a test for wget() (untested -- see NOTE) * lib/strncasecmp: Fix cut'n'paste error in function name. * NSH: Added wget command (untested -- see NOTE). * examples/sendmail: A simple sendmail example (untested -- see NOTE) NOTE: Features related to wget and sendmail are not tested on the target platform in this release and, hence, most likely have problems. I don't have the correct network setup to perform that testing now (I'm in a hotel). 0.4.5 2009-04-19 Gregory Nutt * Add an enumeration argument to the SPI chip select and status methods so that the interface can handle more than one device. * eZ80Acclaim!: Add a generic SPI driver for all eZ80 boards. * Add a setmode() method to the SPI interface to handle parts with differing mode requirements. * include/nuttx/i2c.h: Defined a standard I2C interface * eZ80Acclaim!: Add an I2C driver. * eZ8Encore!: Add an I2C driver. * Add support for the Freescale i.MX1/L architecture and a configuration for the Freescale MX1ADS development board. * examples/helloxx: Added a simple C++ hello world example * include/css: Added std header files * libxx: New C++-only directory provides support for minimal C++ applications 0.4.6 2009-05-19 Gregory Nutt * Change SPI interface so that is can accomodate interfaces where the number of bits per word is greater an 8 (such as with many 9-bit display interfaces). -- this might have broken a few things which will need to be retested! * arch/arm/src/imx: Added i.MX SPI driver * SPI: Add a method to set the number of bits per word. Also add an alternative interface for so that (eventually) I can phase the sndblock and recvblock methods and replace them with a single exchange method * Build: objcopy fails with toolchains that use newer GCC and binutils. The following arguments need to be included in the objcopy command line "-R .note -R .note.gnu.build-id -R .comment" This has been fixed in arch/arm/src/Makefile, but other architectures may have the same problem. Thanks to Dave Marples for verifying this. * configs/eagle100/ostest: Added support for the MicroMint Eagle100 board. This board has a Luminary LM3S6918 Cortex-M3. Added a configuration to build examples/ostest. * arch/arm/src/lpc214x: Add configuration option to enable fast GPIO (vs. legacy, "slow" GPIO) for LPC214x. * arch/arm: Restructured the arch/arm directory structure to better support ARM and Cortex-M3. * sched/: pthread_create() must return a (non-negated) errno value on failure. * configs/eagle100/nsh: Add a NuttShell (NSH) configuration for the Eagle-100 0.4.7 2009-05-29 Gregory Nutt * arch/arm/src/lm3s: Added an Ethernet driver for the LM3S6918 * configs/eagle100/nettest: Added an examples/nettest configuration for the Micromint Eagle100 board. * Documentation/NuttxPortingGuide.html: Added a section on NuttX device drivers. * configs/eagle100/httpd: Added an examples/uip configuration for the Micromint Eagle100 board. * arch/arm/src/lm3s: Added an SSI driver for the LM3S6918 * examples/nsh: Added MMC/SD support for the LM3S6918 * arch/arm/src/lm3s: Fix logic for setting and clearing output GPIOs (critical fix!). * drivers/mmcsd: Found numerous errors in current MMC/SD SPI driver. Bad frequency calculation based on CSD settings, inappropriate timeouts, odd code that looks like a bad search and replace. Also needs support for SDHC ver 2.x. New MMC/SD is largely redesigned and probably non-functional in the first check-in. * drivers/mmcsd: Changes verified on 4Gb Kingston microSHDC card and on a 2Gb SanDisk microSDC card on the Eagle100 platform. * fs/fat: With the 4Gb card, the first tests of FAT32 were (finally) performed. Found and corrected a problem that prevented use of FAT32: It was not updating the sector cache before checking the FAT32 FSINFO sector. * configs/eagle100/*/Make.defs: Added configuration options that should make it possible to build NuttX for the Eagle100 using CodeSourcery 2009q1 toolchain and the devkitARM GNU toolchain. * configs/mcu123-lpc214x/src: Corrected some logic in the LPC2148 SPI receive block logic. Re-verified SDC ver1.x support with 1Gb Toshiba SDC, 1Gb PNY SDC, and 4Gb Kingston SDHC. There are CMD0 issues with the 2Gb SanDisk SDC on this board. * fs/fs_mount.c: Corrected error handling that could cause a deadlock on certain mount() failures. 0.4.8 2009-06-13 Gregory Nutt * lib/lib_*stream.c: Extend internal stream logic to support incoming streams. * arch/arm/src/str71x: Serial output is now correct and timer interrupts are working. The test at configs/olimex-strp711/ostest passes. This means that the basic STR-P711 port is complete. * configs/olimex-strp711/nsh: Add and verified a NuttShell (NSH) configuration for the STR-P711. * arch/arm/str71x/str71x_serial.c: The STR711 interrupt driven serial driver finally works after some extradinary measures to handle missed interrupts. NSH is fully functional on the Olimex STR-P711 board. * example/nsh: Moved architecture specific files from NSH directory to board- specific directories. * config/olimex-strp711/src/up_nsh.c: Add an NSH board specific directory for for the Olimex STR7P11 board. * Fixed build of LM3X6918 using the CodeSourcery Windows native toolchain. There were lots of issues with Cygwin paths and Cygwin symbolic links. These changes may work with the devarmKIT as well, but that remains untested. * The NXP LPC2148 and STR711 targets can now also be built using the CodeSourcery or devkitARM Windows native toolchains. 0.4.9 2009-06-26 Gregory Nutt * Add strtoll() and strtoull(); Add macros for atol() and atoll(). * dup() and dup2() will now clone socket descriptors * All socket descriptors are now cloned when a new task is started via task_create(). * Add configuration options to suppress or eliminate cloning of file and/or socket descriptors when a new task is started by task_create(): CONFIG_FDCLONE_DISABLE, CONFIG_FDCLONE_STDIO, CONFIG_SDCLONE_DISABLE. * Use of C++ reserved word 'private' in C header files causes problems for C++ that include them. * Added 'binfmt' support to allow execution of programs in a file system, binding to NuttX symbols. A custom format call NXFLAT is used; this derives from http://xflat.sourceforge.net. At present is supports on XIP execution from ROMFS file systems. Initial check-in is untested and probably breaks many builds. * examples/lib: Added qsort() * examples/nxflat: Added support for symbol tables * Correct logic that creates compiler include paths. On Cygwin, the include paths for Cygwin-based GCC were being converted to windows native paths. That causes many problems -- breaking dependencies for one. * Fixed an important bug in ROMFS. The initial XIP offset was set incorrectly so if sector zero was read first, there was a bad read. I don't know how it worked before. * arch/arm/src/common/up_use_stack.c. Fixed a fatal stack setup error. This file has been around for a long time, but I don't think it has every been used before (i.e., prior to the NXFLAT logic) 0.4.10 2009-08-08 Gregory Nutt * lib/: Added some basic regex-subset, pattern matching functions * lib/: Greatly simplified mktime() and gmtime_r(). The Gregorian and Julian time calculations were interesting, but not necessary in the typical embeddd system. * sched/: Added gettimeofday(). This implementation is simply a thin wrapper around clock_gettimer(). * lib/: Add gmtime(), localtime(), and strftime() * binfmt/: Add exec(). This is just a wrapper that executes both load_ and exec_module() in a more familiar manner. It is not consistent with more standard exec() functions, however, because (1) it returns and (2) it requires symbol table arguments. * lib/: Add fileno() * examples/ostest: Several of the tests used a big, hard-coded stack size when creating test threads (16K stacksize). The stack size should be controlled by the .config file or the OSTest won't work on platforms with memory constraints. * netutils/thttpd: An initial port of Jeff Poskanzer's THTTPD HTTP server. See http://acme.com/software/thttpd/. * examples/thttpd: A basic test program for THTTPD * configs/eagle100/thttpd: A build configuration for THTTPD on the Micromint Eagle-100 LMS6918 (Cortex-M3) board. * configs/ntosd-dm320/thttpd: A build configuration for THTTPD on the Neuros DM320 platform. * lib/: Added strstr() and strpbrk(). * net/recvfrom.c and net/accept(): Sockets now support some non-blocking operations, specifically for (1) TCP/IP read operations when read-ahead buffering is enabled, and (2) TCP/IP accept() operations when TCP/IP connection backlog is enabled. * fs/fs_fcntl.c and net/net_vfcntl.c: Minimal support provided for fcntl(). It can, at least, be used to mark sockets as blocking or non-blocking. * net/net_close.c: Fix bug in close(). If reference count not set to zero then uip_tcpfree() will assert when DEBUG is enabled. * net/accept.c: Fix bug in accept(). The logic expected parts of the return address structure to be initialized or it would return an error. 0.4.11 2009-09-16 Gregory Nutt * fs/fs_read.c and fs/fs_write.c. read() and write() to socket is the same as recv() and send() with flags = 0. Fixed! * net/recvfrom.c: Fix errors in return value from non-blocking socket read. * lib/lib_strcasecmp.c and lib/lib_strncasecmp.c. Use of post-incremented argument to macro caused strcasecmp() and strncasecmp() to fail. * lib/lib_strstr.c: Length of substring off by one causes false alarm sub-string matches. * arch/arm/src/lm3s/lm3s_ethernet.c: Fix errors in LMS6918 FIFO length handling. (1) The incorrect size of the Ethernet header was being subtracted on outgoing messages (4 vs 14), which caused outgoing messages to be a little too long. (2) The size of incoming FIFO messages is 6 bytes larger than it expected (2 for the length and 4 for the FCS). The unhandled extra two bytes of length cause the driver to sometimes read one too many words from the received FIFO (corrupting the next queued receive packet, if any). * net/net_poll.c and net/uip/uip_tcpbacklog.c. Fixed an important race condition bug in polling for connections. The logic worked if the poll was inplace before the connection was received; but the poll failed to awaken if the connection was already pending in the backlog when poll() was called. * net/net_close.c. Fixed another important TCP/IP race condition bug: If the host closes the TCP connection just before the target calls close(), then the close operation may hang indefinitely! * net/net_tcppoll.c. Removed an unnecessary check for outstanding, un-ACKed data. The NuttX socket layer keeps track of ACKs and doesn't need this check; removing the check should improve write throughput * Add DEBUG configuration option to enable debug console output without disabling optimization (and vice versa) * Changed lots of occurrences of debug macro dbg() to lldbg(). dbg() uses stdout to output debug data. That works fine unless (1) the dbg() macro is interrupt logic and the interrupted task has redirected stdout! Most changes were in uIP. * net/uip/uip_tcpinput.c. Connection reference count was not being set correctly when a socket is created by accepting a new connection. Since the reference count is bad, such sockets are not successfully duplicated when being passed to new tasks. * net/net_clone.c. Similarly, after a socket is cloned, its reference count was not being initialized. * lib/lib_strstr.c. Improperly incremented pointer could cause comparison failures. * net/. Connection reference count must always be set to zero before calling uip_tcpfree() or it could trigger a DEBUGASSERT that verifies that the reference count is zero before freeing a connection structure. * net/uip/uip_listen.c. uip_accept() consulted the wrong list to find the listener on a socket. The previous logic worked most of the time, but occasionally picked the wrong listener. * net/net_close.c and net/net_sockets.c. Sockets were not being closed when a task exits. If many server tasks are created and exit without closing sockets (such as with CGI tasks), then eventually, you will run out of sockets. * netutils/thttpd. Basic functionality of THTTPD is complete. This includes serving up files from a file system and executing NXFLAT-based CGI programs and pipe the stdout back to the HTTP client. 0.4.12 2009-10-17 Gregory Nutt * arch/arm/src/stm32 and configs/stm3210e-eval. Added basic support for the STMicro STM32, Cortex-M3 MCU. The specific port is to the STMicro STM3210E-EVAL development board based around the STM32F103ZET6 MCU. * configs/stm3210e-eval/RIDE. Added a basic STMicro RIDE7 project that can be used to perform basic STM32 board bring-up (due to RIDE7 size limitations, it cannot be used for the full NuttX bring-up). * configs/stm3210e-eval/ostest. The STM32 now passes the basic NuttX OS test at examples/ostest. The rest should be a piece of cake. * configs/stm3210e-eval/nsh. Added NuttShell (NSH) example. * configs/stm3210e-eval/src/stm32102e-internal.h. Fix on-board LED GPIO definitions. * arch/arm/src/stm32/src/stm32/stm32_dma.c. Added DMA channel support for the STM32 * arch/arm/src/stm32/src/stm32/stm32_spi.c. Added a DMA-based SPI driver for the STM32. * arch/arm/src/stm32/src/stm32/stm32_serial.c. Finished interrupt-driven, USART console driver. This makes NSH work perfectly. * Things left to do for the STM32 deferred to the 0.4.13 release: USB device driver, LCD driver and NX bringup on the eval board's display and MicroSD support. An SPI driver was included in the 0.4.12 release, but is not yet tested. 0.4.13 2009-11-04 Gregory Nutt * include/nuttx/mtd.h. Added a simple interface definition to support some FLASH, EEPROM, NVRAM, etc. devices. * driver/mtd/m25px.c. Added a driver for SPI based FLASH parts M25P64 and M25P128. * configs/stm3210e-eval/usbserial. Add a USB serial configuration for the STM32. Depends on the STM32 USB driver. * arch/arm/src/cortexm3/up_switchcontext.S & up_svccall.c. Made an improvement to context switching. There are two types of context switches: interrupt context switches and background/user context switches. This change should improve the performance of those background/user context switches by a factor of about two. * arch/arm/src/stm32/: Fix several typos in the serial logic. It turns out that these typose don't make any difference as long as you use only one serial port and all uarts are configured the same. But the typos are bugs waiting to happen in any other configuration. * arch/arm/src/stm32/: You have to configure CTS/RTS function pins for USART 2 and USART 3 even if you are not using flow control. * arch/arm/src/stm32/stm32_usbdev.c: Added a USB device-side driver for the STM32. NOTE: This is an early release of the USB driver. There is at least one known issue. The examples/usbserial test only executes correctly under certain conditions (see the full bug description in the TODO list). * arch/arm/src/stm32/stm32_rcc.c: Fixed an error in clock initialization. On some boards (none of mine), the HSE (high speed external clock) delay loop times out if the optimization level is high. The STM32 then falls back to the HSI (internal clock), and the system clock is too slow by a factor of 11.1%. This was fixed by simply add the volatile storage class to the timeout loop counter * arch/arm/src/stm32/stm32_irq.c: Fixed a critical bug in the interrupt control logic. The wrong register was being used for interrupts in a certain range. Worked fine until you try to use an interrupt in that range! 4.14 2009-12-02 Gregory Nutt * arch/arm/src/stm32/stm32_gpio.c: Add support for configure an input GPIO to generate an EXTI interrupt. * config/stm3210e-eval/src/up_buttons.c: Add support for on-board buttons. * include/nuttx/rwbuffer.h: Add generic support for read-ahead buffering and write buffering that can be used in any block driver. * include/nuttx/wqueue.h: Added a generic worker thread that can used to defer processing from an interrupt to a task. * include/nuttx/sdio.h: Defines a generic SD/SDIO interface can can be bound to a MMC/SD driver to provide SDIO-based MMC/SD support. * drivers/mmcsd/mmcsd_sdio.c: Provides an SDIO-based MMC/SD driver. * arch/arm/src/stm32/stm32_sdio.c: Provides an STM32 implementation of the SDIO interface defined in include/nuttx/sdio.h. * fs/fs_mount.c: Correct error handling logic. If the bind() method fails, then a reserved node is left in the tree. This causes subsequent attempts to mount at the location to fail (reporting that the node already exists). This is a problem for block drivers for removable media: The bind method could fail repeatedly until media is inserted. * arch/arm/src/stm32/chip.h & stm32_dma.c: Fixed several definitions that can cause compilation errors when DMA2 is enabled. * arch/arm/src/stm32/stm32_dma.c: Integrated and debugged STM32 DMA functionality that was added in 0.4.12. * configs/stm3210e-eval/usbstorage: Add a configuration to exercise the STM32 with the USB mass storage device class example (examples/usbstorage). * configs/mcu123-lpc214x/up_usbstrg: Move LPC-specific code from examples/usbstorage to configs/mcu123-lpc214x. * configs/stm321e-eval/up_usbstrg: Add STM32-specific logic for the examples/usbstorage test. * arch/arm/src/stm32/stm32_usbdev.c: Fix bugs in STM32 USB device-side driver: (1) Need to disconnect after reset received, (2) Status setup to recover from stall on TX endpoint. 5.0 2009-12-21 Gregory Nutt * arch/hc: Adding framework to support m68hc11/12 * configs/demo9s12ne64: Configuration to support Freescale DEMO9S12NE64 development board (MC9S12NE64 m68hcs12 processor). * drivers/mtd/ftl.c: A FLASH translation layer (FTL) has been implemented. This layer will convert a FLASH MTD interface into a block driver that can be used with any file system. Good performance of this layer will depend upon functioning write buffer support! NOTE: FTL support is untested as of the initial check-in. * Numerous minor changes for m68hc12 to eliminate compilation errors and warnings due to the fact that it uses 16-bit integer types and for casts between uint32 (32-bits) and an mc68hc12 pointer (16-bits). * sys/types: Size of off_t and blkcnt_t should not depend on size of int in the architecture; Removed non-standard type STATUS * include/: Added header files stdint.h, stdbool.h, cxx/cstdint, and cxx/cstdbool * Changed ALL references to non-standard fixed-size types (like uint32, ubyte, etc.) to standard types (like uint32_t, uint8_t, etc.) from stdint.h. Use type bool and {true, false} from stdbool. This effected most of the files in the system! Almost all configurations have been re-built and many have been re-verified in order to get confidence in these changes. * graphics/ and examples/nx: Fix numerous build errors that have been introduced lately. NXGL has suffered some bit-rot from not being used in some of the most recent ports. * The misc/pascal NuttX add-on package has been updated to use the new standard types from stdint.h and stdbool.h and re-integrated with NuttX. The released pascal-2.0 will be the first version that contains the compatible changes. * arch/arm/src/lm3s/lm3s_ethernet.c: Fixed an important bug in the LM3S Ethernet driver: If full packet is received, the packet-too-big check will fail because it needs to subtract 6 from the packet size (to account for the 2-byte packet length and the 4-byte packet FCS in the FIFO). * net/accept.c: Fixed a bad assertion (only happens when debug is enabled). * net/send.c net/uip/uip_tcpseqno.c: Fixed a critical error in the TCP/IP logic. The NuttX port of uIP imcludes logic to send data ahead without waiting for ACKs from the recipient; this greatly improves throughput. However, the packet sequence number was not being updated correctly and, as a result, packets were not be ACKed by the recipient and transfers would sometimes stall. This is a very important bug fix (in fact, I don't understand how TCP/IP worked at all without this fix???) * include/nuttx/arch.h and arch/*/common/up_udelay.c: Change argument of up_udelay() to type useconds_t to avoid warnings when sizeof(int) is 16-bits. * drivers/mmcsd/*: Add casts in constant expressions to avoid warnings when sizeof(int) is 16-bits. 5.1 2010-01-30 Gregory Nutt * arch/arm/src/lpc313x and arch/arm/include/lpc313x: Added framework to support the NXP LPC3131. * Add configs/ea3131. The LPC3131 port for the Embedded Artist EA3131 (LPC3131) is code complete and waiting for me to get hardware in hand. * arch/arm/src/sam3u, arch/arm/include/sam3u, and configs/sam3u-ek - Added the basic framework needed to begin a port for the SAM3U-EK development board. * lib/lib_crc32.c: Add CRC32 logic by Gary S. Brown to lib/. This is the larger (but faster) table look-up version of the CRC32 algorithm. * configs/ea3131/tools: Added a tool to create a image suitable for use with the LPC313x bootloader. * configs/sam3u-3k/ostest: Completed verification of the basic NuttX OS test for the SAM3U. * arch/arm/src/common/up_createstack: stack was always been cleared when it was allocated. This is a good feature for monitoring the stack during debug, but really hurts thread start-up performance. Clearing is now done if CONFIG_DEBUG=y only. Changes was only made for arm, but really should be made for all architectures. * configs/sam3u/nsh: Added NSH configuration for SAM3U 5.2 2010-03-18 Gregory Nutt * arch/arm/src/sam3u/sam3u_pio.c: Fix an address calculation error that caused ports B & C to get mapped to the PIOA base address. This is an important bugfix! (a patch is available) * arch/arm/src/lpc313x/lpc313x_boot.c: Fix an error in the vector initialization was causing a memory fault. * lib/lib_strtod.c: Add strtod() * lpc3131/ea3131: Several bring fixes submitted by David Hewson. The lpc3131 is almost there! Thanks David! * arch/arm/src/arm/up_head.S: Corrected backward conditional compilation that selects if vectors are located at 0x0000:0000 or 0xffff:f000. This fixes the last show stopper bug in the lpc313x bring-up. * configs/ea3131/nsh: Added a NuttShell (NSH) configuration for the EA3131. 5.3 2010-04-11 Gregory Nutt * arch/arm/src/lpc313x/lpc313x_usbdev.c: USB driver for the LPC313x contributed by David Hewson. * configs/ea3131/src/up_ubstrgc.c, configs/ea3131/usbserial, configs/ea3131/usbstorage: USB storage and USB serial example support contributed by David Hewson. * Several important compilation error fixes in lpc313x and (dualspeed) USB code also contributed by David Hewson. * arch/arm/src/sam3u/sam3u_dmac.c: DMA support for the AT90SAM3U. * arch/arm/src/sam3u/sam3u_hsmci.c: SD memory card support for AT90SAM3U (Neither the DMA nor the HSMCI driver are functional on the initial checkin). * drivers/usbdev: Several important fixes to the USB mass storage driver submitted by David Hewson. * configs/olimex-lpc2378, arch/arm/include/lpc2378, and arch/arm/src/lpc2378 - Basic port of the NXP 2378 on the Olimex board contributed by Rommel Marcelo. * arch/arm/src/sam3u/sam3u_internal.h: Fixed a critical bug in the AT91SAM3U PIO decoding. No PIOs greater than 15 could be used on any port! Obviously, no one has been using this port. 5.4 2010-04-23 Gregory Nutt * include/nuttx/lcd.h: Defines an LCD interface. * graphics/nxglib/fb and lcd: Support LCD and framebuffer rasterizers for NX. * configs/sam3u-ek/src/up_lcd.c: LCD driver for LCD on SAM3U-EK development board. * configs/sam3u-ek/nx: NX graphics configuration for the SAM3U-EK 5.5 2010-05-09 Gregory Nutt * drivers/net/enc28j60.c: Microchip ENC28J60 SPI Ethernet chip driver. (untested on original check-in). * configs/olimex-str7p11/nettest: examples/nettest configuration using the ENC28J60 driver on the Olimex STMicro STR-P711. (unverified on original check-in) * configs/olimex-str7p11/src/up_enc28j60.c: Add ENC28J60 initialization logic. * configs/olimex-str7p11/src/up_spi.c: Fixed some bugs; added support for ENC28J60. * arch/arm/src/str7x/str7x_xti.c: Add basic XTI support (external interrupts). * arch/arm/src/lm3s and arch/arm/include/lm3s: Add definitions for LM3S6965 * configs/lm3s6965-ek: Add configuration for Stellaris LM3S6965 Evaluation Kit (including basic examples/ostest configuration) * lib/lib_dtoa.c and lib/lib_dtoa.c: printf will not print floating point values if you select CONFIG_LIBC_FLOATINGPOINT in your configuration file. Contributed by Yolande Cates. NOTE: these floating point operations have not been well tested and may not be portable to all floating point implementations. * configs/lm3s6965-ek/nsh: Added NuttShell (NSH) configuration for the LM3S6965 Evaluation Kit. Includes both serial and telnet interfaces. * net/net_close.c: Correct a UDP reference counting error 5.6 2010-06-05 Gregory Nutt * drivers/lcd/p14201.c: Driver for RiT P14201 series 128x96 4-bit OLED. * configs/lm3s6965-ek/nx: NX graphics configuration for the LM3S6965 Ethernet Evaluation Kit. * graphics/: Numerous fixes to get the P14201 4-bpp grayscale display working (there may still be some minor issues .. see the TODO list). * arch/arm/include/lpc17xx and arch/arm/src/lpc17xxx: Began port for NXP LPC1768. As of the 5.6 release, there is a complete set of LPC17xx header files defining all bits in all LPC17xx registers, but little else (I still do not have hardware in hand). * drivers/mtd/m25px.c: Add support for M25P1 flash part (See NOTE) * include/nuttx/i2c.h: Extended I2C interface definition to handle multiple transfers (See NOTE). * include/nuttx/usbdev.h: Corrected an important macro definition needed to correctly handle USB null packet transfers (See NOTE). * arch/arm/src/lpc313x: New drivers: I2C and SPI. Plus several important LPC313x USB bug fixes (See NOTE). NOTE: Contributed by David Hewson. 5.7 2010-06-22 Gregory Nutt * configs/nucleus2g: Add ostest configuration for the Nucleus 2G LPC1768 board from 2G Engineering (http://www.2g-eng.com/) * arch/arm/src/lpc17xx: Added basic LPC17xx boot-up logic, interrupt handling, and GPIO configuration. * configs/nucleus2g/ostest: Completed bring-up of LPC1768 on the Nucleus2G board using the examples/ostest * configs/nucleus2g/nsh: Added and verified a NuttShell (NSH) configuration for the LPC1768 on the Nucleus2G board. 5.8 2010-07-18 Gregory Nutt * configs/nucleus2g/src/up_nsh.c and up_ssp.c: Add support for SPI-based MMC/SD cards and integrate into the NSH example. * arch/arm/src/lm3s/lm3s_vectors.S: Correct vectors for GPIOC & D interrupts. * arch/arm/src/lpc17xx/lpc17_clockconfig.c: Power was not being provided to GPIO module. This is a critical bugfix! * arch/arm/src/lpc17xx/lpc17_serial.c: Improved logic to handle missed TX interrupts. * arch/arm/src/lpc17xx/lpc17_ssp.c: Fix a hard fault during SSP initialization. * configs/nucleus2g/src/up_led.c: Change how LEDs are controlled so that they can be used both for NuttX instrumentation and by application software. * include/net/uip/igmp.h and uip-igmp.h: Add header files ini preparation for NuttX IGMP support * net/uip/uip_igmp*.c: Add IGMP support (untested on initial checkin). * examples/igmp: Add a trivial test for IGMP (much more is needed) * configs/nucleus2g/usbserial and usbstorage: Add USB configurations for testing purposes. * arch/arm/src/common/up_internal.h, cortexm3/up_assert.c, */*_vectors.S: Correct compilations errors when CONFIG_ARCH_INTERRUPTSTACK is enabled (feature still not tested) 5.9 2010-08-25 Gregory Nutt * examples/nsh/nsh_telnetd.c: Fix compilation errors that happen when both DHCPC and TELNETD are enabled in the Nuttshell. * graphics/nxglib/fb/nxglib_moverectangle.c: Fix a logic error that caused an uninitialized variable warning. I still don't have a test to prove that the changes are correct. * configs/olimex-lpc2378: Add support for the CodeSourcery toolchain under Linux (contributed by Alan Carvalho de Assis). * arch/arm/src/lpc17xx/lpc17_gpio.c: Fix an important GPIO configuration bug: When attempting to set no pull-up or pull-down (floating), it would, instead, select pull-down. * arch/arm/src/lm3s/lm3s_gpioirq.c: Fix warning for returning a value from functions returning void (contributed by Tiago Maluta). * netutils/dhcpc/dhcpc.c: lease_time was not in host order * examples/uip/main.c: if DHCPC is selected, this example now shows the assigned IP address. * arch/arm/src/lm3s and arch/arm/include/lm3s: Definitions for the TI LM3S9B96 contributed by Tiago Maluta. * arch/arm/src/lm3s/lm3s_gioirq.c: Fix a logic error in the address table lookup. * arch/arm/src/lm3s/lm3s_gioirq.c: Also needs to enable the global GPIO interrupts. * arch/arm/src/lm3s/lm3s_internal.h and lm3s_gpio.c: Fixed the encoding of GPIO port number that limited support for GPIO ports to 8 * sched/pg_*.c and *.c and include/nuttx/page.h: Implemented the common, core logic for on-demand paging. See http://www.nuttx.org/NuttXDemandPaging.html for details. * drivers/usbdev/usbdev_serial.c: Correct compilation errors that occur if CONFIG_USBDEV_DUALSPEED is selected. * configs/ea3131/pgnsh: Add an NSH configuration with on-demand paging enabled. This is not expected to be a functionality configuration (at least not yet); it was created in order to debug the on-demand paging feature. * configs/ntosd-dm320/*/Make.defs: Codesourcery and devkitARM toolchains now supported for the Neuros OSD. * configs/ntosd-dm320 and arch/arm/src/dm320: Add support for the Neuros production OSD (changes contributed by bf.nuttx). 5.10 2010-09-07 Gregory Nutt * configs/ea3131/locked: Create logic to support a two pass build process: The first pass forces critical logic into the locked text region, the second pass builds the NuttX executable more-or-less as normal. * Makefile, arch/arm/src/Makefile, configs/ea3131: Add logic to support a two-pass final link. This logic is only in place in the arch/arm/src/Makefile for now. * arch/arm/src/lpc17xx/lpc17_internal.h: Add missing parentheses in macros definitions (patch submitted by Tiago Maluta). * Documents/NuttxPortingGuide.html, configs/README.txt, etc. - Replaced CONFIG_EXAMPLE with CONFIG_APP_DIR (see documents for description). This allows NuttX application code to be built outside of the examples/ directory. For people who have their own configurations and/or Makefiles, you will need to make a couple of changes: - Replace all occurrences of CONFIG_EXAMPLE=foobar with CONFIG_APP_DIR=examples/foobar in all of the configuration files. - Replace any occurrences of examples/$(CONFIG_EXAMPLE) with $(CONFIG_APP_DIR) - Replace any occurrences of lib$(CONFIG_EXAMPLE)$(LIBEXT) with libapp$(LIBEXT) in your Makefiles. - Check any other occurrences of CONFIG_EXAMPLE. * arch/arm/src/lpc313x/lpc313x_spi.c: Fix compilation error when when CONFIG_DEBUG is enabled. * arch/arm/src/lm3s and arch/arm/include/lm3s: Support for the lm3s8962 contributed by Larry Arnold. * configs/lm328962-ek: Support for the TI/Stellaris EKC-LM3S8962 board (also contributed by Larry Arnold). * arch/arm/src/lpc313x/lpc313x_boot.c: The call to lpc313x_boardinitialized() should not be conditioned on CONFIG_ARCH_LEDs being defined! * arch/arm/src/lpc313x/: APB0 and APB1 cannot lie in different sections; they are too close together. * arch/arm/src/lpc313x/lpc13x_boot.c: Resetting all of the clocking had a side effect of wiping out the first 6 words of memory where the interrupt vectors are located (and also not resetting the fractional dividers). This is not usually noticeable because the IRQ vectors are after this point, but really causes problems if you want to handle data and prefectch aborts which are within this zeroed region. 5.11 2010-10-01 Gregory Nutt * configs/ea3131/src/up_fillpage.c: Added new configuration item CONFIG_PAGING_BINPATH. If CONFIG_PAGING_BINPATH is defined, then it is the full path to a file on a mounted file system that contains a binary image of the NuttX executable. Pages will be filled by reading from offsets into this file that correspond to virtual fault addresses. up_fillpage.c implements logic to perform page files using the CONFIG_PAGING_BINPATH file. * configs/mbed: Add configuration to support the mbed.org LPC1768 board (Contributed by Dave Marples). * sched/sem_wait.c and sem_waitirq.c: Eliminate a race condition that can occur when a semaphore wait is interrupt by a signal. (see email thread: https://groups.yahoo.com/neo/groups/nuttx/conversations/messages/530) * drivers/mtd/at45db.c: Add a driver for the Atmel AT45DB161D 4Mbit SPI FLASH part (untested on initial check-in). * arch/arm/src/lm3s and arch/arm/include/lm3s: Corrections for the lm3s8962 port contributed by Larry Arnold. That port is purported to work correctly with these changes in place. * examples/ostest/prioinherit.c: Need to reinitialize globals if test is ran repeatedly in a loop. * configs/ez80f910200zco: Updated to used ZDS-II 4.11.1 5.12 2010-10-26 Gregory Nutt * arch/avr: Add a place to support AVR family processors. * arch/avr/include/avr32 and arch/avr/src/avr32: Add support for AVR32 (all of the AVR32 is a work in progress). * arch/avr/include/at32uc3 and arch/avr/src/at32uc3: Add support for the AVR32 UC3A/B family of AVR32 MCUs. * configs/avr32dev1: Add support for the Atmel AVR32DEV1 board featuring the AT32UC3B0256 MCU. This board is produced by www.mcuzone.com. * include/stdlib.h, lib/Makefile, lib/lib_abs.c, lib/lib_labs.c, lib_labs.c, lib_llabs.c, lib_imaxabs.c: Add abs(), labs(), llabs(), and imaxabs(). * Add include/inttypes.h * arch/hc/src/mc9s12ne64: This hcs12 port grew a few more files. But it is still a long way from complete. * arch/*/src/*/*_sigdeliver.c: Fixed a serious error in the signal trampoline logic. Essentially, interrupts are re-enabled while the signal handler executes, but the logic to re-disable the interrupts before returning from the signal handler trampoline was missing. Under certain circumstances, this can cause stack corruption. This was discovered by David Hewson on an ARM9 platform, but since the code has been leveraged, the bug has been propogated from ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80, Z8, and Z80 -- almost every architecture. The correction has been incorporated for all architectures but only verified on a few. 5.13 2010-11-09 Gregory Nutt * lib/lib_strnlen.c: Added POSIX 2008 strnlen() function. Contributed by Michael Hrabanek. * Fix wild, consistent naming error. For some reason, I called the at32uc3* parts at91uc* everywhere. Fixed by changing lots of files and directories. * configs/avr32dev1/ostest: The AVR32 port now successfully passes the examples/ostest. We have a good AVR32 port! * configs/avr32dev1/nsh: Added a configuration to support the NuttShell (NSH). As of this writing, here is a problem receiving serial data (this is, very likely, my hardware setup). * lib/lib_open.c: Fix an error in fdopen when a valid file descriptor does not refer to an open file. * configs/olimex-lpc1766stk: Add support for the Olimex LPC1766-STK development board. The OS test and NSH configurations (only) have been verified. 5.14 2010-11-27 Gregory Nutt * configs/olimex-lpc1766stk/nettest: Add examples/nettest configuration to verify the LPC17xx Ethernet driver currently under development. * arch/arm/src/lpc17xx/lpc17xx_ethernet.c/.h: Began development of the LPC17xx Ethernet driver. Driver in CVS functional after 2010-11-23. * sched/timer_settime.c: Fix an error in set-up of a one-shot POSIX timer. It was using the repititive timer value (which is zero in the one-shot case), always resulting in a 10Ms timer! Found and fixed by Wilton Tong. * arch/arm/src/lpc17xx/lpc17_vector.S, stm32/stm32_vector.S, lm3s/lm3s_vector.S, sam3u/sam3u_vector.S: Fixed a hard fault problem that can occur if certain types of interrupts are pending at the time another interrupt returns (SYSTICK). This has not been verified on all plaforms, but is a critical fixed that is needed by all Cortex-M3 NuttX users. * configs/olimex-lpc1766stk/thttpd: Add a THTTPD configuration for the Olimex LPC2766-STK board. Verified successfully. * net/uip/uip_tcpappsend.c: Correct an important logic bug in some uIP state data the is used to manage retransmissions. The uIP logic was incompatible with the retransmission logic of net/send.c in one place. The final error was that the final packet in a sequence of packets was too large! In the THTTPD example, this would leave some garbage at the bottom of the display (or worse). I don't know why I haven't see this bug before??? * net/uip/uip_tcpinput.c: The change to uip_tcpappsend.c unmasked an additional error in the TCP sequence number handling. This sympom was that the send() function would hang with outstanding, unacknowledged data (with no re-transmit requests). The was due to differences in sequence number handling in send() and in uip_tcpinput.c; uip_tcpinput.c thought (incorrectly) that all of the bytes were acknowledged; send.c knew that they were not. 5.15 2010-12-12 Gregory Nutt * net/uip/uip_tcpaddsend.c and net/send.c: Another place where the TCP sequence number problem "fixed" in 5.14 might occur. * net/send.c: Check if the destination IP address is in the ARP table. If not, then don't consider the packet sent. It won't be, an ARP packet will go out instead. This improves behavior, for example, on the first GET request from a browser. * arch/arm/src/lpc17xx/lpc17_emacram.h and lpc17_allocateheap.c: The Ethernet logic was using all of AHB SRAM Bank0 for Ethernet packet buffers (16K). An option was added to limit the amount of SRAM used for packet buffering and to re-use any extra Bank0 memory for heap. configs/olimex-lpc1766stk/nettest now uses only 8K at the beginning of Bank0; the 8K at the end of Bank0 is included in the heap * arch/arm/src/lpc17xx/lpc17_ssp.c: Fix compilation errors when SSP1 is selected. * configs/olimex-lpc1766stk/nsh: Enable network and SD/MMC card support in NSH. Networking and telnetd interface as well as SPI-based microSD are now functional. * examples/nsh/nsh_netinit.c: Fix NSH bug. If CONFIG_NET is selected, but CONFIG_EXAMPLES_NSH_TELNETD is not selected, then the network is never initialized and bad things happen if you try to ping. * drivers/lcd: Add header files for the Phillips PCF8833 LCD controller and for the Epson S1D15G10 LCD controller. A driver for the Nokia 6100 LCD is coming. * include/nuttx/spi.h and almost all other SPI files: Added an optional cmddata() method to the SPI interface. Some devices require an additional out-of-band bit to specify if the next word sent to the device is a command or data. This is typical, for example, in "9-bit" displays where the 9th bit is the CMD/DATA bit. The cmddata method provides selection of command or data. * drivers/lcd/p14201.c: Now uses the cmddata() method of the SPI interface. * arch/arm/src/lpc17xx/lpc17_usbdev.c: LPC17xx USB driver now appears to to be fully functional. examples/usbstorage configuration verified (the examples/usbserial configuration is untested). * drivers/usbdev/usbserial.c and usbstorage.c: All USB class drivers need to call DEV_CONNECT() when they are ready to be enumerated. That is, (1) initially when bound to the USB driver, and (2) after a USB reset. * drivers/lcd/nokia6100.c: A driver for the Nokia 6100 LCD. This driver has not be verified as of the initial check-in. * configs/olimex-lpc1766stk/nx: A NX graphics configuration for the Olimex LPC1766-STK board using the Nokia 6100 LCD driver. This configuration has not been verified as of the initial check-in. * include/nuttx/spi.h: the SPI_SETBITS macro was calling the setmode method. This is a very important bug-fix in some usages. 5.16 2011-01-10 Gregory Nutt * include/nuttx/usb: Created new directory. Moved all usb-related header files to this new directory. Created a skeleton for a new USB host header file * drivers/usbhost: Add USB host "registry" where connect devices can be matched with the correct USB class driver. * arc/arc/src/lpc17xx/lpc17_usbhost.c: Add a simple USB host driver for the NXP lpc17xx. * drivers/usbhost: Add generic USB device enumeration logic. * drivers/usbhost: Add a USB host class driver for the (Bulk-Only) USB Mass Storage Class. 5.17 2011-01-19 Gregory Nutt * include/nuttx/usb: rename usb_storage.h to storage.h. * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for low-speed devices. * drivers/usbhost/usbhost_skeleton.c: Template for new class drivers * include/nuttx/usb/hid.h and drivers/usbhost/usbhost_hidkbd.c: New files for HID keyboard support. * arch/arm/src/lpc17xx/lpc17_usbhost.c: Will now handle multiple concurrent transfers on different endpoints (still only one TD per endpoint). All methods are protected from re-entrancy; lots of re- structuring in preparation for interrupt endpoint support. * arch/arm/src/lpc17xx/lpc17_usbhost.c: Add support for periodic interrupt transfers. * examples/hidkbd: Added a simple test for the USB host HID keyboard class driver. * configs/olimex-lpc1766stk/hidkbd: Added a configuration to build the USB host HID keyboard class driver test for the LPC17xx. * Ran the tool CppCheck (http://sourceforge.net/apps/mediawiki/cppcheck) and fixed several errors in the code identified by the tool. 5.18 2011-02-27 Gregory Nutt * Incorporate several uIP patches from http://gitweb.aeruder.net/?p=uip.git;a=summary. - Lost SYNACK causes connection reset - Fix missing UDP stats for sent/received packets - Added support for Cygwin as development/test platform. * configs/demo9s12ne64: Integrate new buildroot-1.9 m8s12x toolchain. * 'uname -o' is used throughout the build logic in bash scripts and also in Make.defs files in order to distinguish between Cygwin and Linux. However, the -o option is not standard and is not supported under, for example, OS-X or Solaris. This was solved by changing all 'uname -o' references to the more complex: 'uname -o 2>/dev/null || echo "Other"' * drivers/usbhost/usbhost_enumerate.c: Add logic to get the VID and PID. This is necessary in order to support vendor-specific USB devices. * examples/wlan, configs/olimex-lpc1766stk/wlan, drivers/usbhost/usbhost_rtl8187.c, Add infrastructure to support RTL18187 wireless USB. * configs/nucleus2g: backed out USB host changes... wrong board. * Renamed arc/hc/include/mc9s12ne64 and src/mc9s12ne64 to m9s12. That name is shorter and more general. * The NuttX repository has been converted to SVN and can now be found here http://svn.code.sf.net/p/nuttx/code/trunk/ * configs/mbed/hidkbd: Added USB host support for the mbed LPC1768 board; add a USB host HID keyboard configuraion. * drivers/usbhost/hid_parser.c: Leverages the LUFA HID parser written by Dean Camera. * examples/nsh: Correct an usage of getopt(): If you stop calling getopt() before all parameters are parsed, you can leave getopt() in a strange state. * include/nuttx/video/fb.h: Restore missing RGB type that was accidentally removed when Nokia 6100 support was added. * Rename arch/pjrc-8051 to arch/8051 * configs/ne64badge: Add a configuration for the Future Electronics Group NE64 Badge development board (Freescale MC9S12NE64) * Changes contributed by Uros Platise: - Add support for the STM32F103RET6 - configs/vsn: Support for the ISOTEL NetClamps VSN V1.2 ready2go sensor network platform * arch/hc, configs/ne64badge: Development is complete for the Freescale mc9s12ne64 on the Future Electronics Group NE64 /PoE Badge board. Howeve, this port remains untested until I figure out this BDM / Code Warrior and paged build thing * Added a new 'kill' command to NSH that will support sending signals to running NuttX tasks. 5.19 2011-03-12 Gregory Nutt * arch/arm/stm32/stm32_idle.c: During idle times, the STM32 now uses the WFI instruction to sleep in a reduced power mode until the next interrupt occurs (Contributed by Uros Platise). * NSH: 'mem' command renamed to 'free'. Output is now more similar to the Linux 'free' command. * NSH: Correct a redirection bug in NSH. The following would not work; it resulted in a hang after the 'cat /dev/fifo': nsh> mkfile /dev/fifo nsh> cd /tmp # /tmp is a mounted RAM disk nsh> cat /dev/fifo > test.txt & nsh> echo "This is a test" > /dev/fifo The error was caused because (1) there was a path that resulted in stdout being closed (the "hang") and also (2) the 'cat' command was always outputting to stdout, not to the redirected file descriptor. Now: nsh> cat test.txt This is a test * drivers/pipes/pipe_common.c: Driver open method was not returning an EINTR error when it received a signal. Instead, it just re-started the wait. This makes it impossible to kill a background pipe operation from NSH. * include/stdint.h: Correct some errors in conditional compilation (submitted by Johannes Hampel). * arch/arm/lpc17xx/lpc17_idle.c: Uses the same logic as the STM32: uses the WFI instruction to sleep in a reduced power mode until the next interrupt occurs. * configs/olimex-lpc1766stk: Added an LED encoded to indicate if the LPC1766 is in sleeping. * examples/mm: This is a simplified version of the "built-in" memory manager test of mm/mm_test.c. It is simplified because it does not have access to the internals of the memory manager as does mm/mm_test.c, but it has the advantage that it runs in the actual NuttX tasking environment (the mm/mm_test.c only runs in a PC simulation environment). * drivers/mmcsd_sdio.c/h: Several corrections submitted by Uros Platise. * arch/x86: Provide support for x86 architectures. Support for the i486 architecture under QEMU is provided under arch/x86/include/i486, arch/x86/include/qemu, arch/x86/src/i486, and arch/x86/src/qemu. * configs/qemu-i486: "Board" support configurations for verifying the QEME i486 port. * arch/arm/src/stm32/stm32_spi.c: Correct base address of SPI3 (reported by Uros Platise). * drivers/mmcsd/mmcsd_sdio.c: Correct a loop termination condition (also reported by Uros Platise). * drivers/mtd/ramtron.c: Driver for SPI-based RAMTRON NVRAM devices FM25V10 (and others). Contributed by Uros Platise. * examples/nsh and tools/mkromfsimg.sh: Add support for platform-specific ROMFS-based NSH start-up scripts. * drivers/serial/uart_16550.c and include/nuttx/serial/uart_16550.h: Support for a generic 16550 UART. * configure/qemu-i486/nsh: QEMU NSH example. * ../apps: The apps directory add-on was created by Uros Platise. It supports a set of end-user applications than can be executed on top of NSH. Think of it this way: In a buckled-up embedded application, your end-user programs will probably have their own dedicated start-up logic. But, during development, you might want to have you applications available and executable from the NSH command line. This apps/ addon (and NSH hooks) was contributed by Uros to accomplish just that. * sched/sched_waitpid() and include/sys/wait.h: Provides a simple and very incomplete implementation of waitpid(). waitpid() is only available if CONFIG_SCHED_WAITPID is defined in your configuration file. * sched/atexit.c and sched/exit.c: The atexit function is not frequently used. In order to save a few bytes, it is now conditioned on CONFIG_SCHED_ATEXIT. It your application is currently using atexit(), you will need to add CONFIG_SCHED_ATEXIT to your configuration file. * drivers/net/slip.c: Add a SLIP driver (untested on initial check-in). * configs/olimex-lpc1766stk/slip-httpd: An example that uses SLIP to provide a serial-port based THTTPD web server. 6.0 2011-03-21 Gregory Nutt * lib/lib_fopen(): fopen() was not returning the correct errno value when the underlying open() failed. * include/net/uip/uip-arch.h: The uIP interface has been extended slightly so that drivers can be concurrenly filling and sending packet buffers. This capability was needed by the SLIP driver. * drivers/net/slip.c: Several corrections and some re-design of of the driver. * apps/ChangeLog.txt: the apps/ directory now has its own ChangeLog. * configs/vsn: - IDLE LED blinking fix - Added board power off function * arch/arm/src/stm32/stm32_gpio.c and stm32_internal.h: Fixed PullUp/Down Input Configuration. * arch/arm/src/lpc17xx/lpc17_serial.h: Now supports Auto-RTS and Auto-CTS modes. This is needed to support SLIP. * drivers/net/slip.c: SLIP is now basically functional on the LPC17xx with some caveats as described in the TODO list under LPC17xx. * arch/x86/include/i486/irq.h: Fix irqrestore() macro... it was not correctly re-enabling interrupts. * arch/x86/src: Fix numerous problems with i486/QEMU context switching. Basically, the logic was missing the cases to handle the differing stack frames when a priority change occurs and when no priority change occurs. * configs/qemu-i486/ostest and nsh: The QEMU i486 port is complete. it now passes the OS test and supports the NuttShell (NSH). * misc/drivers: Created a new directory to hold non-BSD licensed drivers that may be added into NuttX via an installation script. * drivers/usbhost/usbhost_rtl8187.c: A decision was made to incorporate code taken from the Linux kernel. That changes the licensing on this module to GPL. To avoid licensing contamination, this driver was moved to misc/drivers/rtl8187x *prior* to adding any of the GPL logic. There is an INSTALL.sh script at the location where the GPL driver(s) can be re-installed into the NuttX source tree. By re-installing the driver, you agree to the GPL licsensing and all of its implications. * Makefile, apps/Makefile, tools/configure.sh: Add logic to copy configs///appdir to apps/.config and to simply the application configuration logic. * examples/nsh and apps/nshlib: Move the core NuttShell (NSH) logic out of the exemples directory and into the apps/ directory where it belongs. * apps/Makefile and configs/*/appconfig: Use '=' as the delimiter instead of '/' so that sub-directories in apps/ can be used. * apps/vsn: Move all VSN apps to apps/vsn. * nuttx/examples moved to apps/examples 6.1 2011-04-11 Gregory Nutt * arch/arm/include/lpc17xx/irq.h and arch/arm/src/lpc17xx/lpc17_gpio*.c: Fix several bugs in the GPIO interrupt logic. Submited by Decio Renno. * Initialization for the CONFIG_APPS_DIR is now supported during the earlier, 'context' build phase. * arch/arm/src/lpc17_gpioint.c: Finish coding of the LPC17xx GPIO interrupt logic. * net/netdev_unregister.c: Add capability to un-register a network device. * drivers/mmcsd/mmcsd_sdio.c: extra effort to correctly handle cases without the SDcard (but one issue still exists in STM32) * arch/arm/src/stm32/stm32_tim.*: Added basic timer support TIM1..TIM8 with output PWMs and interrupt logic * config/vsn/src: Added basic support for Sensor Interface (GPIO and PWM Power Output, and the sif utility program) * fs/: Reorgnize header so that file systems can be built outside of the nuttx source tree * apps/namedapp/binfs.c: Create a tiny filesystem that can be used to show the internal named apps under /bin. * fs/fs_opendir.c: Correct an error that occurs when a file system is mounted in the root directory. This was discovered while mounting the named app's /bin directory. * lib/: Move all source files into a subdirectory of lib/ named after the header file in which the library function is prototyped. * sched/ and lib/pthread/: Move pthread attribute-related interfaces from sched/ to lib/pthread where they more appropriately belong. * sched/ and lib/semaphore/: Move some semaphore-related interfaces from sched/ to lib/pthread where they more appropriately belong. * syscall/: The beginnings of an optional syscall Kernel interface. * tools/mksyscall.c: Add a tool that will auto-generate syscall proxies and stubs from a comma-separated-value (CSV) data file. * arch/arm/src/cortexm3/mpu.h: Add a header file describing the Cortex-M3 MPU registers. * Numerous modifications to the build system. Various people have reported build problems since the re-organization and release of NuttX-6.0. I am unable to replicate the build problems in my environment, but the changes have be incorporated in hope of correcting the build issues in other environments. * drivers/i2c/st_lis331dl.c: I2C-based driver for the LIS331DL MEMS motion sensor. Contributed by Uros Platise. * Makefile: The NuttX build system will now supported building NuttX as two separately linked images: (1) a kernel-mode RTOS image, and (2) a user- mode application image that communicates to the RTOS kernel via system calls. A lot more still must be done. * user_initialize(): Eliminated the user_initialize() initialization hook. It is difficult to maintain and redundant: Board level initialization an up_initialize() provide the same kind of capability. * arch/*/include/*/type.h: On some compilers, char defaults as unsigned. Explicitly add signed to integer types if signed is what is required. * arch/*: For all architectures -- Global register state save structure (usually called g_current_regs) should be marked volatile; Added general capability to support nested interrupts (not fully realized for all architectures). * sched/task_create.c: Add support for starting kernel-mode thread. * drivers/usbdev/usbdev_serial.c: Fix reported by Sheref Younan. USB was being reset after serial driver was closed. As a result, you could no reopen the serial driver. * configs/lpcxpresso-lpc1768: Add a board configuration for the Embedded Artists LPCXpresso LPC1768 board. 6.2 2011-05-06 Gregory Nutt * arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct errors in logic that maps and IRQ number into a register bit number. * Makefile: Fix an error introduced in the top-level Makefile in NuttX-6.1. This error only shows up if you have a /tftpboot directory. Then the make will fail with an obscure error about not being able to stat pass2. * configs/lpcxpresso-lpc1768/nsh: Add an NSH configuration for the LPCXpresso board. * configs/*/ld.script: Removed 'sh_link not set for section .ARM.edix' for a few of the builds. In you have this warning, it can be removed with the following change to the ld.script file: + __exidx_start = ABSOLUTE(.); .ARM.exidx : { - __exidx_start = ABSOLUTE(.); *(.ARM.exidx*) - __exidx_end = ABSOLUTE(.); } >sram + __exidx_end = ABSOLUTE(.); * arch/arm/src/lpc17xx: Correct some typos/bugs in configuration of LPC17xx UART2 and UART3. * nuttx/clock.h: Replace all references to the global variable g_system_timer with clock_systemtimer() (currently just a macro that that returns g_system_timer). * lib/string/strrch.c: Would fail if the searched-for character were the first character in the string. * tools/version.sh and mkversion.c: Tools to manage a NuttX version number file * sched/clock_getutc() and lib/time/lib_time.c: Add support for 1 second UTC interface. * net/net_dup2.c and include/nuttx/net.h: The conditional compilation for '#if CONFIG_NFILE_DESCRIPTOR > 0' was wrong in both of these files. It should be '#if CONFIG_NFILE_DESCRIPTORS > 0'. This causes a dup2() failure in THTTPD and a failure to get a CGI page. The consequence can be a very serious bug! * configs/lpcxpresso-lpc1768/usbstorage, thttpd, and dhcpd: Add an USB storage, THTTPD web server, and DHCP server configurations for the NXP LPCXpresso board. * drivers/lcd/ug-9664hswag01.c and ssd1305.h: Add support for Univision UG-9664HSWAG01 OLED with Solomon Systech SD1305 LCD controller. * configs/lpcxpresso-lpc1668/nx: Add a NX graphics configuration for the LPCXPRESO board. * graphics/nxglib/nxglib_nonintersecting.c: Fix some single bit errors in calculation of non-intersecting regions. This was causing an anomaly in examples/nx in column 0. * drivers/mtd/rammtd.c: Added a RAM based MTD driver. This RAM driver simulates FLASH and is useful for testing purposes. * arch/arm/src/arm/up_head.S: Fix backward conditional compilation. This cause the configs/mx1ads configuration to fail to build but does not appear to affect any other ARM9 build. * fs/nxffs: Adding a tiny, wear-leveling FLASH file system for NuttX. This file system is intended to be small and will have some limitations. The implementation is incomplete on initial checkin. * apps/examples/nxffs and configs/sim/nxffs: Add a test a a configuration that will be used to verify NXFFS. * fs/fat/fs_fat32.c and fs_fat32util.c: Incorpated two bugs with fixed provided by Sheref Younan. Thanks! * fs/nxffs: After a couple of weeks of testing and bug fixes, NXFSS appears stable and functional. 6.3 2011-05-15 Gregory Nutt * Remove clock_getutc(). It is replaces with clock_gettime(CLOCK_ACTIVETIME). Add other RTC related changes provided by Uros Platise. * arch/arm/src/stm32/stm32_flash.c: Add support for access to on-chip STM32 FLASH; beginning of integration with NXFFS (Uros Platise). * arch/mips: Added directory structure for PIC32 support * configs/pcblogic-pic32mx: Add directory structure for PCB Logic PIC32MX board * apps/include: Move include/apps to apps/include. A symbolic link is created at build time * Makefile: Removed support for Pascal pcode interpreter. Support for that interpreter has been moved to apps/interpreter/Makefile. * tools/mkdep.sh: Should not report an error if there are no files on the command line. This happens normally in certain configurations. * drivers/usbhost: Sheref Younan reported an error in the error handling when connection to a USB device fails. In certain fail cases, the logic would try to free the device class instance twice, the first was okay, but the second caused a crash. * graphics/nxbe/nxbe_colormap.c: Fix error noted by Bassem Fahmy. The function nxbe_colormap was change to nxbe_configure... apparently "search-and-replace" error. This error was not noticed before because most NX platforms do not use colormapping. * arch/rgmp and configs/rgmp. Add architecture support and build configuration for RGMP. RGMP is a project for running GPOS and RTOS simultaneously on multi-processor platforms. See http://rgmp.sourceforge.net/wiki/index.php/Main_Page for further information about RGMP. * lib/stdio/lib_fclose.c: Must flush all buffered data when the file is closed. Instead, it was discarding the buffered data. * lib/stdio: All output stream logic was modified to support CONFIG_STDIO_LINEBUFFER. If standard C buffered I/O is enabled (CONFIG_STDIO_BUFFER_SIZE > 0), then this option may be added to force automatic, line-oriented flushing the output buffer for putc(), fputc(), putchar(), puts(), fputs(), printf(), fprintf(), and vfprintf(). When a newline is encountered in the output string, the output buffer will be flushed. This (slightly) increases the NuttX footprint but supports the kind of behavior that people expect for printf. 6.4 2011-06-06 Gregory Nutt * lib/drivers/cc1101: Add initial, functional CC1101 wireless driver (contributed by Uros Platise) * arch/mips and configs/pcblogic-pic32mx: The MicroChip PIC32MX port is now code complete and ready to begin testing. Unfortunately, it looks like testing will be delayed due to tool issues (My PICkit 2 will not work the the MPLAB debugger on PIC32; I will need to get a PICkit 3). * drivers/net/e1000.c/h: A PCI-based E1000 Ethernet driver submitted by Yu Qiang. * lib/net/lib_inetaddr.c: An implementation of the inet_addr() function submitted by Yu Qiang. * arch/arm/src/lpc31xx and arch/arm/include/lpc31xx: Renamed from lpc313x to make name space for other famiy members. * arch/arm/*/lpc31xx: Added support for the LPC315x family (untested). * sched/task_exithook.c: Functionality performed when a task exits or is deleted has been moved to a common file task_exithook.c. Now exit() functionality (like flushing I/O and calling registered atexit() functions, etc.) will be performed when a task is deleted as well. * mm/: Added support for CONFIG_MM_SMALL. Each memory allocation has a small allocation overhead. The size of that overhead is normally determined by the "width" of the address support by the MCU. MCUs that support 16-bit addressability have smaller overhead than devices that support 32-bit addressability. However, there are many MCUs that support 32-bit addressability *but* have internal SRAM of size less than or equal to 64K. In this case, CONFIG_MM_SMALL can be defined so that those MCUs will also benefit from the smaller, 16- bit-based allocation overhead. * lib/string/lib_strndup.c: Add standard strndup() library function. * net/getsockname.c: Added standard getsockname() to return the local address associated with a socket. * lib/stdio/lib_asprintf.c: Add asprintf() * configs/olimex-lpc1766stk/ftpc: Add a configuration to support testing of the FTP client shell. * fd/fs_fdopen.c and net/net_checksd.c: Add support so that fdopen may be used with socket descriptors. * net/recvfrom.c: Fix an error found in receiving small files via FTP: The small file is received a buffered in the readahead buffer, then the socket is disconnected. When the app calls recvfrom, the socket is already disconnected and the buffered data is stranded. Now, recvfrom will continue to return success after the socket is disconnected until the readahead buffer is drained. * olimex-lp1766stk/ftpc/defconfig: Many configurations have the MTU (CONFIG_NET_BUFSIZE) set to very small numbers, less then the minimum MTU size that must be supported -- 576. This can cause problems in some networks: CONFIG_NET_BUFSIZE should be set to at least 576 in all defconfig files. This has only been fixed in this defconfig file. 6.5 2011-06-21 Gregory Nutt * arch/avr/src/avr and arch/avr/include/avr: Adds general support for the Atmel 8-bit AVR family. * arch/avr/src/atmega and arch/avr/include/atmega: Adds support for the Atmel AVR ATMega family. * arch/avr/src/at90usb and arch/avr/include/at90usb: Adds support for the Atmel AVR AT90USB family. * configs/micropendous3: Adds a board configuration for the Opendous Micropendous 3 board. This board may be populated with several different members of the Atmel AVR AT90USB family. * configs/amber: This is a placehold for the Atmel ATMega128 Amber Web Server from SoC Robotics. Not much present in this directory on initial check-in. * configs/teensy: Adds a board configuration for the PJRC Teensy++ 2.0 board that features an Atmel AT90USB1286 MCU. * fs/fat: Offsets, sector numbers, etc. need to be off_t, not size_t. size_t is intended to be the maximum size of a memory object, not a file offset. This does not make any difference except on systems (like the AVR) where size_t is only 16-bits. 6.6 2011-07-11 Gregory Nutt * drivers/mtd/ramtron.c, net/net_checksd.c, fs/fs_fdopen.c, and include/nuttx/mii.h: Several structural changes made to get a clean compile under the ez80 ZDS-II toolchain (no design changes). * drivers/usbhost/usbhost_storage.c: Incorpated bugfixes reported by Sheref H. Younan: (1) Read capacity logic read largest block, not the number of blocks and was, therefore, off by one, and (2) Some devices stall of get Max LUN request if they support only a single LUN. Logic now assumes a single LUN if the get Max LUN request fails. * include/nuttx/arch.h, lib/stdio/lib_libvsprintf.c, lib/stdio/lib_fputs.c: Add a new configuration option to support extracting strings from FLASH or EEPROM or other memories where the string data cannot be accessed by simply de-referencing a string pointer. * arch/sim/src/up_romgetc.c: Used to test the basic logic to access strings without directly de-referencing a string pointer. * arch/avr/src/avr/up_romget.c: Used to access strings that lie in the first 64K of FLASH (But I still haven't figured out how to get strings to reside in FLASH without using the PROGMEM attribute). * configs/teensy/src/up_spi.c: Correct reading of SD CD and WP pins (was reading the wrong register. AVR SPI now appears to be functional. * arch/avr/src/at90usb/at90usb_usbdev.c: Correct USB initialization. Interrupts were being enabled BEFORE the interrupt handler was attached. * configs/sure-pic32mx: Add a configuration for the Sure Electronics, "Advanced USB Storage Demo Board," Model DB-DP11215 (http://www.sureelectronics.net/goods.php?id=1168). This board features the MicroChip PIC32MX440F512H MCU. (Untested on initial check-in). * configs/stm3210e-eval/nsh2: Add another NSH configuration for the STM32 with some different properties. * CONFIG_NSH_CONDEV: Add a configuration option to allow using a different character device (such a a different UART) for the NSH interface. This allows, for example, debug output to come from the console device while using another device for NSH. There are some issues on initial check-in: NuttX doesn't have termios and the console device has special properties that make using NSH awkward. Examples: No CR-LF expansion, no character echoing, no command line editting. * arch/arm/src/stm32/stm32_lowputc.c and stm32_serial.c. Correct seversl bugs involving serial port configuration. These bugs are only critical if you are trying to using multiple UARTs on STM32. * configs/stm3210e-eval/src/up_lcd.c: Add a driver for the STM3210E-EVAL's LCD. * configs/stm3210e-eval/nx: Add NX configuration for the STM3210E-EVAL. * configs/nuttx/arch.h (and arch/arm/src/stm32, configs/*/src/up_buttons.c): Standardize interfaces exported for button support and button interrupts. * configs/stm3210e-eval/src/up_buttons.c: Add interrupting button support. Also fixes a few errors in STM3210E-EVAL button decoding. * configs/stm3210e-eval/buttons: Add a configuration to exercise STM3210E-EVAL buttons. * arch/arm/src/stm32/stm32_gpio.c: GPIO interrupt handling for pin numbers were being aliased: 5-9 together and 10-15 together. Extended the logic to peform decoding of GPIO interrupts and unique dispatching for all 16 pins. * configs/stm3210e-eval/nxtext: Add a configuration for the apps/examples/nxtext example. This example focuses on placing text on the background while pop-up windows occur. Text should continue to update normally with or without the popup windows present. * arch/arm/src/common/up_checkstack.c: ARM stack overflow checking submitted by Hal Glenn. * arch/arm/src/lpc17xx: Changes to compile successfully with no serial console (also submitted by Hal Glenn). * graphics/nxfonts/nxfonts_convert.c: Fixed a critical bug that caused when renderer some fonts with bits-per-pixel > 8 * graphics/nxbe/nxbe_move.c: Fixed an error in the graphics move logic (This was a previously untested interface). Basically, there is some confusion between use of (x,y) as a relative offset or as an absolute position. * graphics/nxbe/nxbe_close.c: Fixed an important graphics system bug: When a window is closed, the display was not being updated. The old window graphic was left on the display for a time. 6.7 2011-08-02 Gregory Nutt * Makefile: Added a export target that will bundle up all of the NuttX libraries, header files, and the startup object into an export-able tarball. * arch/arm/src/lpc17xx/lpc17_can.h: Correct some typos in the CAN register definitions. * drivers/serial/serialirq.c: Correct an error that can occur if the serial RX buffer becomes full. Data is now discarded in that case; before, leaving data in the hardware would cause infinite interrupts one most MCUs since you must read the data in order to clear the interrupt. * arch/arm/src/lpc17xx/lpc17_can.c: Added a CAN driver contributed by Li Zhuoyi (Lzyy). * include/stddefs.h and sys/types: Added type wchar_t. * fs/fat/fat_fat32dirent.c: Move all FAT directory operations to this new file; Implement VFAT long file name support. * fs/fat/fat_fat32dirent.c: The configuration CONFIG_FAT_LCNAMES has been around for some time but never tested until now. This setting will mimic the NT 8.3 file name behavior: File names or extensions may be all upper or all lower case (but not mixed). If CONFIG_FAT_LCNAMES is not selected, all filenames are strictly upper case. * configs/stm3210e-eval/nsh2: Console is back on UART1; Added examples/nx as an NSH "built-in" command as a demonstration. * fs/fat/fs_fat32dirent.c: Fix an important bug in the directory allocation (fat_allocatedirentry()). I looks like it could be initializing the wrong sectors! NOTE: This function was in fs_fat32utils.c in earlier releases. * arch/arm/src/stm32_sdio.c: Correct an important DMA-related bug; SDIO transfer completion events and DMA completion eventes were not being coordinated correctly. * configs/stm3210e-eval/nsh2: Enable FAT long file name support * sched/sem_timedwait.c: Add the standard sem_timedwait() interface. * graphics/nxfonts/nxfonts_getfont.c, nxfonts_bitmap.c, Makefile.source, and include/nuttx/nxfonts.h: Support for multiple fonts included. A new interface, nxf_getfonthandle() takes a font ID and returns a handle that is now used at all other font interfaces to specify which of the multiple fonts to use. * arch/arm/src/lpc17xx/lpc17_syscon.h: Fix typo (reported by Li Zhuoyi). * configs/stm3210e-eval/nsh2: Extended to support two new commands: 'msconn' will connect the USB mass storage device; 'msdis' will disconnect the USB storage device. * tools/bdf-converter.c. This C file is used to build the bdf-converter program. The bdf-converter program be used to convert fonts in Bitmap Distribution Format (BDF) into fonts that can be used in the NX graphics system. * include/nuttx/nx: Move all NX header files from include/nuttx to include/nuttx/nx. * drivers/usbdev/usbdev_usbstorage.c and arch/arm/src/stm32/stm32_usbdev.c: Correct a memory leak when the USB mass storage driver is connected and then disconnected from the target. The write requests were not being freed. NOTE that the unregister logic in the STM32 needed to call stm32_reset() in order to return the write requests to the USB mass storage driver; it is possible that a similar but could exist for other architectures. * graphics/nxfonts/nxfonts_*.h: Add serveral more new fonts * arch/z80/src/ez80/ez80_serial.c: Fix some errors in serial driver setup for UART1 (submitted by Paul Osmialowski). * drivers/input/tsc2007.c and include/nuttx/input/*: Add a generic NuttX touchscreen interface. Add a driver for the TI TSC2007 touchscreen controller. * graphics/nxglib/lcd and fb: Add low level routines to set single pixels. * lib/math/lib_b16atan2.c: Add a fixed precision atan2() function * graphics/nxglib/nxglib_splitline.c: Add logic to divide a wide line into trapezoidal components. * graphics/nxmu/nx_drawline.c, graphics/nxsu/nx_drawline.c, graphics/nxtk/nxtk_drawlinewindow.c, graphics/nxtk/nxtk_drawlinetoolbar.c: Add new line drawing interfaces (untested). 6.8 2011-08-19 Gregory Nutt * arch/arm/src/lpc17xx/chip.h: Fix some chip memory configuration errors for the LPC1764, LPC1756, and LPC1754 (submitted by Li Zhuoy (Lzyy)) * arch/arm/src/lpc17xx/lpc17_can.h: Revised CAN driver submitted by Li Zhuoy (Lzyy). The driver now supports both CAN1 and CAN2. * arch/arm/sim/up_lcd.c: Add a simulated LCD driver. * configs/stm3210e-eval/nxlines: Added a configuration to build examples/nxlines. * arch/graphics: Used apps/examples/nxlines to (finally) verify the NX trapezoid drawing functions and (wide) line drawing functions. * arch/rgmp and configs/rgmp. Yu Qiang has ported RGMP to the OMAP4430 (arm) pandaboard and release the new RGMP 0.3 version. The main changes are: (1) Separate configs/rgmp/x86 and configs/rgmp/arm configuration directory, and (2) Extract architecture dependent code in arch/rgmp/include and arch/rgmp/src into corresponding x86/ and arm/ directories. * arch/arm/src/kinetis, arch/arm/include/kinetis, configs/kwikstick-k40: Add a directory structure to support the port to the Kinetis KwikStik-K40. There is no real substance in the initial check-in; only the directory structure and skeleton files (Code complete on 8/15/11). * arch/arm/include/armv7-m, arch/arm/src/armv7-m, etc.: Rename all cortexm3 directories and files to armv7-m; Change name of of all CORTEXM3 constants to ARMV7M. This is a major namespace change needed to cleanly support the ARM Cortex-M4 which is also in the ARMv7 M Series (specifically, ARMv7E-M). * sched/sig_initialize.c, sig_received.c, and mq_waitirq.c. Fixed several critical bugs related to signal handling initialization and for signals the wake up tasks that are waiting to send or receive message queues. In the first two files, errors would prevent proper allocation of signal-related structures from interrupt handlers. In the second, there was missing "clean-up" logic after a signal occurred, leaving the message queue in a bad state and resulting in PANICs. All are important. (submitted by hkwilton). * arch/arm/src/kinetis: Added header files defining all Kinetis registers and bit fields within all Kinetis registers. * configs/twr-k60n512: Add support for the Kinetis K60 Tower board (TWR-K60N512). * drivers/can.c: Fixed a semaphore overflow problem in the CAN driver (reported by Li Zhouy (Lzyy)). * 8/18/2011: The basic port to the FreeScale Kinetis TWR-K60N512 board is now functional. * configs/twr-k60n512: Add Kinetis TWR-K60N512 NSH configuration. * drivers/analog and include/nuttx/analog: Add ADC driver infrastructure and TI ADS1255 driver developed and submitted by Li Zhouy (Lzyy)). * arch/arm/stm32/stm32_sdio.h and drivers/mmcsd/mmcsd.c: Add logic to multiplex usage of the GPIO pins (contributed by Uros Platise). * configs/twr-k60n512/nsh: Added and verified a NuttShell (NSH) configuration for the Freescale, Kinetis TWR-K60N512 board. 6.9 2011-09-11 Gregory Nutt * arch/arm/src/kinetis/kinetis_sdhc.c: SDHC driver for Kinetis parts. Initially check-in is just a crude port of the STM32 SDIO driver. Much more work is needed. * graphics/, include/nuttx/nx: Add new NX interfaces for drawing circles -- both circular outlines and filled circles. * graphic/nxglib/nxglib_spitline.c: Add a "fudge factor" that eliminates some problems for rendering nearly horizontal, wide lines. Hmm... but I suspect this fudge factor also leads to new problems rendering very thin, nearly horizontal lines. More tuning is needed. * drivers/analog, include/nuttx/analog, arch/arch/src/lpcxx: (1) Add updates to the ADS1255 driver, (2) fix errors from my last merge (sorry), (3) Add DAC infrastructure, (4) add AD5410 DAC driver, and (5) add LPC17xx ADC and DAC drivers. All contributed by Li Zhuoyi (Lzyy). * tools/mkexport.sh: Extended the script that implements the top-level 'make export' logic. The script now also finds and bundles up all of the architecture-specific header files as well. * drivers/arch/arm/src/stm32/stm32_i2c.c: Add a reset to the I2C initialization logic to prevent spurious interrupts when the I2C interrupts are enabled (submitted by Uros Platise). * Scripts/makefiles/documents. Several adjustments, corrections and typo fixes so that NuttX will build correctly on FreeBSD using the ASH shell (submitted by Kurt Lidl). * drivers/mtd/flash_eraseall.c: Add a callable function that accepts the path to a block driver and then erases the underlying FLASH memory (assuming that the block driver is an MTD driver wrapped in the FTL layer). Hmmm... this is probably not the best long term solution; flash_eraseall() should be a user-callable function that operates one driver interfaces; not an internal, OS function that operates on directly on block drivers. * drivers/bch: Fixed some important bugs in the BCH driver (noted by Li Zhuoyi (Lzyy)). This would have effected any large reads or writes (larger than the hardware sector size). * arch/*/src/Makefile: Use of -print-libgcc-file-name to get path to libgcc.a may select the wrong libgcc.a if a multilib toolchain (like CodeSourcery) is used. This can be a serious problem and can cause crashes on Cortex-M3 if the ARM libgcc is used, for example. The fix is to include ARCHCPUFLAGS on the gcc command line when asking it to -print-libgcc-file-name. * lib/time/lib_gmtimer.c: Correct several calculations that could lead to errors in dates. * drivers/pm: Add the beginnings of a NuttX power management sub-system. * arch/arm/src/stm32/stm32_irq.c: Fix a error introduced in 6.8. Timeout calculation uses clock_settime() instead of clock_gettime(). Pretty gross error, but actually it works with the side effect of setting a bad time. * drivers/mtd/at24xx.c: Driver for I2C-based at24cxx EEPROM submitted by Li Zhuoyi (Lzyy). * arch/arm/src/lpc17xx/lpc17_i2c.c: I2C driver for the NXP LPC17xx family submitted by Li Zhuoyi (Lzyy) * arch/arm/src/stm32_i2c.c: Correct two issues with the STM32 I2C driver: (1) Clocking needs to be based on PCLK1, not HCLK and fast speed settings need some additional bits; and (2) Correct a hang that will occur on I2C1 if FSMC is also enabled. * drivers/sensors/lm75.c and include/nuttx/sensors/lm75.h: Add an LM-75 temperature sensor driver. * configs/stm3210e-eval/src/up_lm75.c: Add support for the LM-75 on the STMicro STM3210E-EVAL board. * sched/clock_gettime.c: Correct an error in the tv_nsec calculation that happens only config CONFIG_RTC is enabled. * arch/arm/src/stm32/stm32_i2c.c: Correct some bugs related to waiting for the I2C STOP condition to be cleared. 6.10 2011-10-06 Gregory Nutt * lib/stdio/lib_fopen.c: Fix an error in fopen(); the file pointer was not being positioned at the end of the file when the "a" and "a+" modes are used. There are other issues with the "a+" modes (see the top-level TODO list). * drivers/usbdev/cdc_serial.c and include/nuttx/usb/cdc.h and cdc_serial.h: Add support for the CDC ACM serial device class. * fs/fat/fs_fat32.c: Fix a critical bug in the write logic: It a tiny write cross a sector boundary, then two sector writes will occur. The first part in the first sector may be written to the wrong sector number. * fs/fat/fs_fat32util.c: Fix a stray write into the FAT (always sector 964 on FAT32). This bug will cause some lost chains. I'm sure this bug could corrupt files but at present, the only thing I have seen is that before fixing this bug, the Windows chkdsk utility would report these lost chains. * arch/arm/src/stm32/stm32_i2c.c: Driver can now operate in a faster polled mode (at the expense of using more cpu cycles). * arch/arm/src/stm32/stm32_i2c.c: Add trace debug capability. Enabled with CONFIG_I2C_TRACE. * arch/arm/src/stm32/stm32_i2c.c: Fix another bug where I2C conflicts with FSMC being enabled. That time at the tail end of the transaction where there is an unfinished stop condition. * sched/mq_timedreceive.c and sched/mq_timedsend.c: The count of threads waiting on the message queues was not being decremented after a timeout. This would cause the accounting logic to become out of sync and the, perhaps, an assertion to be triggered. This is an important bug and fixes a potential crash when using mq_timedreceived() and mq_timedsend(). * sched/mq_sndinternal.c: Related to the above, the send logic was incrementing the wrong counter when it waited as part of the mq_timedsend.c logic. * fs/fat: Fix an error in the long file name logic: If the long file name is an even multiple of 13 bytes in length, then it should not include a NULL terminating character. Fix contributed by Kaushal Parikh. * configs/sim/nx11: Created a separate configuration to build the NX example using the a simulated framebuffer driver on an X11 window. This example has been verified on Ubuntu 9.09 (it does not work on Cygwin). * arch/sim/src/up_touchscreen.c and up_x11eventloop.c: Adds support for a simulated NuttX touchscreen device using mouse/pointer feedback from an x11 window. * configs/sim/touchscreen: Adds a configuration to verify the simulated touchscreen driver (Does not work on Cygwin). * configs/sam3u/touchscreen: This is the configuration that I plan to use to verify the SAM3U-EK touchscreen driver. However, as of this writing, there is no touchscreen driver for the board. * CONFIG_RTC_HIRES: Add an option to support either a high-resolution RTC that completely replaces the system timer tick but may overflow and lose time when the MCU is off and also for a low-resolution (1 sec/tick) RTC that can run until 2106 with no overflow. But in this latter case, higher resolution time must come from the system timer. * CONFIG_SYSTEM_UTC: Removed support for the UTC system timer. It just doesn't do enough to be worth the CPU cycles or the complexity. * CONFIG_SYSTEM_TIME16: Added support for an optional 64-bit system timer. * fs/fat/fs_fat32util.c: Add support for FAT date/time stamps; Enabled via CONFIG_FS_FATTIME. * arch/arm/src/sam3u/sam3u_spi.c: Add an SPI driver for the AT91SAM3U. * drivers/input/ads7843e.c and include/nuttx/input/ads7843e.h: Add a driver for the TI ADS7843E touchscreen controller. * fs/nxffs/nxffs_open.c: Fix an error when a file is open for writing; since the file will get deleted it is already exists, there must be a check if there are other open references to the file. * arch/arm/src/stm32/stm32_sdio.c: Fixed an error where during SDHC initialization interrupts were not being re-enabled. Caused more subtle errors than you would think. * arch/arm/src/stm32/stm32_i2c.c: Fixed an error where I2C timeouts appeared to be successful transfers. * configs/sim/nsh2: Add another simulated NSH configuration. This one supports X11 graphics, C++, and exercises graphic functions as built-in commands. 6.11 2011-11-12 Gregory Nutt * arch/arm/stm32/Make.defs: Don't build stm32_rtc.c if CONFIG_RTC is not selected. Doing so will cause errors if other configuration dependencies are not met. * configs/stm3210e-eval/src/up_lcd.c: Color corrections for SPFD5408B LCD do not work with R61580 LCD. * configs/pic32-starterkit: Beginning of a configuration for the Microchip PIC32 Ethernet Starter Kit. Hmmm.. I don't have a clue how to test this with no serial port?! * lib/stdio/lib_fclose.c: fclose() always returns an error (EOF) when it closes a read-only file. This is because it calls flush() which will fail on read-only files. No harm is done other that a bad value is returned. * arch/sim/src/Makefile: Correct build issue for sim/nsh2 target. Old libboard.a was not being cleaned. * arch/mips/src/pic32mx/pic32mx-gpio*.c: Add GPIO support for the PIC32MX. * configs/sure-pic32mx/src/up_leds.c and up_buttons.c: Add button and LED support for the Sure Electronics PIC32MX board. * configs/ea3152: Add a configuration for the Embedded Artists LPC3152 daughter board (with the same base-board used with configs/ea3131) * graphics/nxmu/nx_getrectangle.c, graphics/nxsu/nx_getrectangle.c, graphics/mxtk/nx_getwindow.c, graphics/nxmu/nx_gettoobar.c: New interfaces to read from graphics memory * graphics/nxbe/nxbe_bitmap.c: Fix an error in the error handling that can cause valid bitmaps to fail to render. * include/nuttx/video/rgbcolors.h: Fix errors in some 16- and 8-bit color conversion macros. * tools/incdir.sh: Fix issues when g++ is used as the compiler. It was not being recognized and handled properly. * graphics/nxsu/nx_releasebkgd.c: Fix a bad cast that was causing problems with the background window was released. * fs/nxffs/nxffs_pack.c: Correct a critical bug in the NXFFS file system: When repacking the filesystem, there was a missing check to see if an inode structure would fit at the end of a block. This is a rare case if the block size is large, but can be common for tiny block sizes and results in a crash and file system corruption. * fs/nxffs/nxffs_initialize.c: Fix an initialize error. If the FLASH is full on power-up, NXFFS will fail to initialize correctly. * fs/nxffs/nxffs_write.c and nxffs_pack.c: Fix an error that can occur when attempt to write to FLASH volume that is completely full but has no value inodes on it. * drivers/mtd/at24xx.c: Now supports a configurable block size that supports using "clusters" of AT24 pages as blocks. This allows bigger block sizes and more efficient use of EEPROM when the AT24 is used to support a file system (such as NXFFS). (Contributed by Hal Glenn). * include/nuttx/video/rgbcolors.h: More fixes to RGB color conversion macros. * arch/arm/src/common/up_createstack.c and up_usestack.c: For ARM EABI the stack must be aligned to 8-byte boundaries. This is necessary for passing aligned floating point values under EABI. Fix contributed by David Sidrane. * Numerous changes and fixes to the PIC32 interrupt handing logic. The PIC32 port is almost complete but still not ready for prime time. 6.12 2011-12-06 Gregory Nutt * fs/fat/fs_fat32util.c and fs_fat32.h: Logic extended to look in up to four partitions for a valid FAT file system. * drivers/input/tsc2007.c: Add support for 8-bit conversions; make sure that A/D converters are active before requesting conversions. * drivers/mmcsd0/mmcsd_sdio.c: Increase capacity variable from size_t to uin64_t (if available) so that SD cards with capacities greater than 4Gb can be supported. * fs/fat/fs_fat32dirent.c: The root directory structure is different from other directories. When formatted by Windows, it is not initialized at all. Some additional special handling is required to initialize the root directory entry to interoperate correctly with windows. * fs/fat/fs_fat32util.c: In fat_systime2fattime(void) should be clock_gettime() and not clock_gettime(). Also, there is a place where FAT date is used instead of FAT time. (Thanks to David Sidrane). * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the STM32F40xxx family of MCUs. * configs/stm3240g-eval: Add framework for the STMicro STM3240G-EVAL board. * include/sys/types.h: wchar_t is a builtin type in C++ and its declaration can cause errors with certain C++ compilers. * sched/sig_timedwait.c: Fix signal handling when the returned info is NULL. Before this change, it would derefence a NULL pointer in this case. * graphics/nxfonts/nxfonts_sans17x22.h and nxfonts_sans20x26.h: Add some very small sans serif fonts. * graphics/nxfonts/nxfonts_sans17x23b.h and nxfonts_sans20x27b.h: Add corresponding sans serif bold fonts. * drivers/input/ads7843e.c and tsc2007.c: Fix some errors in the poll setup error checking that was cloned into both drivers. * sched/mq_notify.c: Set errno appropriately on failures. There are still several message queue functions that do not set errno! * arch/arm/src/stm32: Fixes to several STM32F40xxx files (contributed by Mikhail Bychek). * configs/stm3210e-eval/src/up_lcd.c: Fix banding problem on the R61580 LCD * configs/stm3240g-eval/ostest: The basic STM32F40xx bringup is functional (11/12/06) for the STM3240G-EVAL board and passes the OS test. * configs/stm3240g-eval/nsh: Adds a NuttShell (NSH) configure for the STM3240G-EVAL board. 6.13 2011-12-26 Gregory Nutt * arch/arm/src/stm32/stm32f40xxx_dma.c: Add DMA support for the STM32 F4 family (untested on initial check-in) * arch/arm/src/armv7-m/up_fpu.c: Add logic for saving an restoring VFP floating point registers on context switches (but also disable the FPU because CodeSourcery doesn't support hard flowing point!) * arch/arm/src/stm32/chip/stm32_eth.h: Add Ethernet register definitions for the STM32 F4. * arch/arm/srcm/stm32/stm32_eth.c: Adds an Ethernet driver for the STM32 F4. * arch/arm/srcm/stm32/stm32_dac.c and stm32_adc.c: "Skeleton" files for STM32 DAC and ADC drivers. The actual logic will come later. * arch/arm/srcm/stm32/stm32_eth.c: There may be a few more lurking bugs, but the STM32 Ethernet driver appears to be fully functional on the STM3240G-EVAL. * arch/arm/srcm/stm32/stm32_eth.c: Fix an error in clearing abnormal interrupt events. * configs/stm3240g-eval/dhcpd: Add a DCHP daemon configuration for the STM3240G-EVAL board. * configs/stm3240g-eval/nettest: Add a network test configuration for the STM3240G-EVAL board. * arch/arm/srcm/stm32/stm32_rtc.c, stm32f10xxx_rtc.c, and stm32f40xxx_rtc: Broke out separate drivers to handle the very different RTC implementations in the STM32 F1 and F4 family. * arch/arm/srcm/stm32/stm32f10xxx_rtc.c: STM32 F4 RTC is functional (12/14/2011) * net/uip-arp.c: Fix compilation issue with CONFIG_NET_ARP_IPIN * include/nuttx/pwm.h and drivers/pwm.c: Add an interface definition and a "upper half" driver for PWM output. * arch/arm/src/stm32/stm32_pwm.c: Added a PWM "lower half" driver for the STM32. The initial check-in is little more than a framework for the driver. * arch/arm/src/stm32/stm32_usbdev.c: Corrected two CRITICAL errors in the USB device-side driver: (1) Handling of data overrun condition was wrong. When there was no further memory to accept further OUT endpoint data, the driver would hang with infinite interrupts; (2) the logic in setting toggle bits was not correct. However, this driver has functioned for a long time until the particular condition that revealed the bug occurred. My impression is that this latter bugfix also fixes some STM32 USB performance problems. * configs/hymini-stm32v: A configuration for the HY-Mini STM32v board contributed by Laurent Latil. These changes also include support for the STM32F103VCT6. * arch/configs/stm3240g-eval/src/up_pwm.c: Add hooks needed to use the new apps/examples/pwm test of the STM32 PWM driver. * drivers/mtd/mp25x.c: Add ability to use different SPI modes and different manufacturers codes. Fix a error in the wait for not busy (submitted by Mohammad Elwakeel. * arch/arm/src/stm32/stm32_can.c: Add a low-level STM32 CAN driver. (Initial check is incomplete). Add loopback support to the driver. * arch/arm/src/stm32/stm32_adc.c: The ADC is now functional. A more complete driver would require DMA support. I have some questions still about the accuracy of the timer-driven sampling. * configs/sure-pic32mx/nsh: The PIC32 port is (finally) functional. Add an NSH configuration for the Sure PIC32MX board. * configs/sure-pic32mx/*/defconfig. Calibrated all PIC32 delay loops. * configs/pcblogic-pic32mx/nsh: Add an NSH configuration for the PCBLogic PIC32 board. * Both PIC32 OS test and NSH configurations have now been verified. 6.14 2012-01-15 Gregory Nutt * tools/Makefile.export, mkexport.sh, and configure.sh: Changes submitted by Mike Smith to support configuration and 'make export' on MAC OS. * arch/arm/src/stm32/stm32_gpio.c: Disabled interrupts while configuring GPIO pins so that we have exclusive access to the GPIO configuration registers. * arch/mips/src/pic32mx/pic32mx_usbdev.c: Add a USB device-side driver for the PIC32MX family. * arch/arm/src/stm32/stm32_gpio.c: Correct an error in some of the GPIO initialization logic. Fix submitted by Mike Smith. * configs/olimex-lpc1766stk/src/up_leds.c: Add new interfaces so that is CONFIG_ARCH_LEDS are not set, the LEDs may be controlled from application logic. * configs/olimex-lpc1766stk/src/up_buttons.c: Add support for the buttons on the Olimex LPC1766-STK board. * Makefile: Added 'apps_clean' and 'apps_distclean' target to simplify managing the state of the application directory while in the NuttX directory * Documentation/NuttXGettingStarted.html: Added a "Getting Started" Guide for NuttX. At present, this is just a stub and it refers to the NuttX top-level README.txt file which is the only, real "Getting Started" Guide that exists at the time being. * arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct an value used as the lower end of an IRQ number range test. * arch/arm/src/lpc17xx/lpc17_gpio.c: Fix a integer flow problem in shift. This error would prevent pins > 15 from being used as interrupt sources. * arch/arm/src/stm32/stm32_can.c: The CAN driver has been verified in loopback mode on the STM3240G-EVAL board. * configs/stm3240g-eval/src/up_adc.c: Complete coding of ADC support for the potentiometer on board the STM3240G-EVAL. * arch/arm/src/lpc17_can.c: Several CAN driver improvements. Adds support for testing in loopback mode. now uses all three transmit buffers for better performance. * configs/olimex-lpc1766stk/nsh: Now supports the CAN loopback test as an optional "built-in" application. * sched/irq_attach.c: Fix an issue with disabling interrupts when they are detached. For the PIC32, this can't be done because there is a 1-to-many relationship between vector numbers and interrupt numbers or different. Added a new configuration option CONFIG_ARCH_VECNOTIRQ to at least flag the architectures that have this issue and to (at least) avoid doing something too wrong. * drivers/can.c: Fix a test for buffer full in the generic, "upper half", can driver. * arch/arm/src/lm3s: Add support for the LM3S6432S2E (Contributed by Mike Smith) * configs/lm3s6432-s2: Add support for the TI RDK-S2E (LM3S6432S2E) board (Contributed by Mike Smith) * configs/stm3240g-eval/src: Add APIs support to support user access to the LEDs * arch/arm/src/lpc17xx/lpc17_can.c: Add logic to change the CAN bit rate based on the NuttX configuration. * arch/arm/src/lpc17xx/lpc17_can.c: PCLK divisor is now a configuration option. * arch/arm/src/stm32/stm32_serial.c and stm32_lowputc.c: Support for UART4-5 and USART6 added by Mike Smith. Also includes a more flexible way of managing UART pin configurations. * include/nuttx/pwm.h, drivers/pwm.c, arch/arm/src/stm32/stm32_pwm.c: Add support for pulse count in order to better support stepper motors. * arch/arm/src/stm32/stm32_dumpgpio.c: Checking wrong register to see if GPIO is enabled. Also not adding the GPIO base address to several offsets. * configs/stm32f4discovery: Port to the STMicro STM32F4Discovery board (Contributed by Mike Smith). * fs/fat/fs_fat32util.c: On a failure to recognize a FAT file system, the mount logic should return -EINVAL, not -ENODEV. * arch/arm/src/stm32/stm32_tim.c: Support for STM32 F4 32-bit timers (Contributed by Mikhail Bychek) * lib/stdio/lib_vsprintf.c: Add support for fixed-size fields with floating point numbers (Contributed by Mikhail Bychek) 6.15 2012-02-12 Gregory Nutt * arch/arm/src/stm32/stm32_pwm.c: Pulse count was limited to 128; now is (essentially) unlimited. * configs/stm3240g-eval/include/board.h: Input frequencies wrong for all but one APB2 timer. * arch/mips/src/pic32mx/pic32mx-ethernet.c: The PIC32 Ethernet driver is code complete, but still untested. * configs/sim/*/Make.defs and arch/sim/src/Makefile: Add support for building a 32-bit executable on a 64-bit Linux target. * configs/sure-pic32mx/src/up_leds.c: Correct GPIOs used for LEDs. The wrong pins were being used. * arch/arm/src/stm32/chip/stm32f10xxx_gpio.h: Correct offset to one AFIO EXICR register. * arch/arm/src/lpc17xx/lpc17_can.c: Added "advanced" configuration options to specify the CAN TSEG1 and TSEG2 clock counts specifically. * include/nuttx/can.h and drivers/can.c: Add support for extended (29-bit) CAN IDs. * arch/arm/src/lpc17xx/lpc17_can.c: Add support for extended (29-bit) CAN IDs. * arch/arm/src/stm32/stm32_can.c: Add support for extended (29-bit) CAN IDs. * include/nuttx/power/pm.h: Move include/nuttx/pm.h into a sub-directory named power. * drivers/power: Rename the drivers/pm directory to power * include/power/battery.h and drivers/battery.c: Add the interface definitions for an upper and lower half battery driver. Add the implementation of the common upper half battery driver. * drivers/power/max1704x.c: Add a driver for MAX17040x battery "fuel gauge" * arch/arm/src/stm32/stm32_i2c.c: Add support for I2C3 * drivers/usbdev/: Lots of name changes: cdc_serial->cdcacm, usbstrg->usbmsc, usbser->pl2303 * drivers/usbdev/composite: Fleshed out support for a composite USB device. * drivers/stm3210e-eval/composite and drivers/stm3210e-eval/src/up_composite.c: Add a configuration test the USB composite device. * include/nuttx/usb/usb.h, drivers/usbdev/composite_descriptors.c, and drivers/usbdev/cdcacm_descriptors.c: Add support for the USB Interface Association Descriptor (IAD) * arch/arm/src/stm32/stm32_i2c.c: Correct a typo in STM32 I2C3 support (submitted by Mike Smith) * arch/*/src/Makefile: Candidate solution for dependency issue in the board sub-directory: By making libboard.a a "phony" target, libboard.a should always rebuilt (the end result is worth the small increase in build time) (submitted by Mike Smith). * include/net/psock.h: Added a new low level socket interface that allows the OS to use the socket interface without having a socket descriptor. * include/net/psock.h: Removed psock.h. The new interfaces are moved into nuttx/net.h which already has similar logic. * include/nuttx/usb/usb.h: Can't use 'class' as a field name in USB structures. This upsets C++ if usb.h is included. 'class' -> 'classid' in this header file and all places that referenced 'class' * drivers/usbdev/usbmsc.c: Fixed some backward conditional compilation. * sched/on_exit.c: Add support for the on_exit() function., * sched/exit.c, task_exithook.c, task_delete.c, sched_releasetcb.c: Move the logic that closes file descriptors sooner in the task shutdown sequence. When drivers are closed, they may need to do things that require a fully up-and-running task. Some things cannot be done later when the task is crippled. * lib/dirent: Moved readdir_r() and telldir() from lib/misc to this new directory where they belong. * lib/termios. Implemented tcsetattr() and tcgetattr(). * lib/stdio/lib_fgets.c: The old fgets includes some terminal related functionality: It handles VT-100 commands, includes a command line editor and echo characters back to the terminal. This old, overloaded fgets() was renamed readline() and moved to apps/system/readline. The version of fgets() in lib/stdio was them simplified and stripped down so that it *only* gets a string -- as its description implies. * arch/arm/src/lpc214x/lpc214x_usbdev.c: Add corrections suggested by David Hewson many, many months ago. * configs/mcu123-lpc214x/composite and configs/mcu123-lpc214x/src/up_composite.c: Add a configuration to test the USB composite device. * configs/stm3240g-eval/Telnetd: Add a configuration for testing the Telnet daemon. * configs/stm3240g-eval/nsh2: This is another NSH configuration. It differs from the original nsh configuration because it does not have an RS-232 console (only a Telnet console) and SDIO is enabled. This configuration is required because the STM3240G-EVAL board cannot simultaneously support RS-232 and SDIO due to pin conflicts. * lib/string/lib_strcasestr.c: Add strcasestr(). * lib/stdio/lib_avsprintf.c: Add avsprintf(). * lib/net/lib_inetntop.c: Add inet_ntop(). * lib/net/lib_inetpton.c: Add inet_pton(). * include/pthread.h: Correct PTHREAD_MUTEX_INITIALIZER. * fs/fat/fs_fatfs.c: Fix an error in the FAT statfs() implementation that was causing some block counts to be reported incorrectly (reported by David Sidrane). * drivers/ramlog.c: Add a character driver that can substitute for /dev/console and or be used for logging debug output when there is no serial port available (such as when a Telnet console is used). * lib/stdio/lib_syslogstream: Add a stream object that will be used to re-direct all debug output to the RAM log if CONFIG_SYSLOG and CONFIG_RAMLOG_SYSLOG are defined. * lib/misc/lib_dbg.c: Add an interface enabled with CONFIG_DEBUG_ENABLE that can be used to turn debug output on and off. 6.16 2012-03-10 Gregory Nutt * drivers/sensors/qencoder.c and include/nuttx/sensors/qencoder.h: Add an implementation for a quadrature encoder upper half driver. * arch/arm/src/stm32/stm32_qencoder.c/.h: Add a initial implementation of a lower-half quadrature encoder driver for the STM32. On initial check-in, this is little more than a "skeleton" file. * Various files: CAN ISO-11783 support contributed by Gary Teravskis. * net/recv.c and net/recvfrom.c: Correct a bug in return value: The the peer gracefully closes the connections, needs to return zero and not ENOTCONN. * arch/arm/src/stm32/stm32_eth.c: Fix an error in the STM32 ethernet driver. The received buffer size must be two bytes larger to account for the two byte checksum that is appended to the packet. Otherwise, the last two bytes of real data in the packet will get clobbered. * arch/arm/src/stm32f40xx_dma.c: The STM32 F4 DMA has (finally) been verified * arch/arm/src/stm32_sdio.c: STM32 F4 SDIO DMA is now supported * configs/stm3240g-eval/nsh/defconfig: This configuration now supports SDIO with DMA (see configs/stm3240g-eval/README.txt for some issues). * arch/arm/src/armv7-m/up_vectors.S and arch/arm/src/armv7-m/up_vectors.S: New, streamlined Cortex-M exception handling (with FPU supported). Contributed byh Mike Smith * net/accept.c, connect.c,and net_monitor.c: Correct an error in the accept logic. After a new connection is made via accept(), monitoring for losses of TCP connection must be set up (just as with connect()). The new file net_monitor.c holds the common TCP connection monitoring logic used by both the accecpt() and connect() logic. Contributed by Max Nekludov. * net/recvfrom.c and net/uip/uip_tcpcallback.c: Fix a leak in the TCP read-ahead logic. This is a *critical* bug fix! * net/uip/uip_tcpinput.c: Correct an error in the TCP stack. It was incrementing the received sequence number BEFORE determining if the incoming data could be handled. If the data was dropped (usually because there is insufficient buffering space), then no ACK will be sent and the sequence number will be wrong. The end consequence of the bad sequence number was that the when the dropped packet was re-transmitted, it was was ignored because its sequence number looked wrong. Fix was, obviously, to only increment the recevied sequence number if the TCP data was accepted. * configs/stm3240g-eval, configs/stm32f40discovery, and arch/*/src/Makefile: Add changes to support building with the Atollic "Lite" toolchain. * fs/fs_select.c: Correct select(), in the case of loss of network connection (POLLHUP), select() must report a read-ready event. This is how the standard select() interface is supposed to work: In the case of loss-of-connection, select() reports read-ready. The next time you read from the socket, you detect the end-of-connection event. Change submitted by Max Nekludov. * arch/arm/src/armv7-m/up_fpu.S and arch/arm/src/stm32/stm32_vectors.S: Fix lazy FPU register saving with CONFIG_ARCH_FPU is set in the configuration. * arch/arm/src/armv7-m: Lazy saving of floating point registers on context switches now seems to be functional. * net/uip/uip_tcpinput.c: Fix a TCP protocol error reported by Max Nekludov. * configs/stm3240g-eval, configs/stm32f40discovery: Add changes to support building with the Atollic "Pro" toolchain. * Makefile: Use the more common .hex extension for Intel hex files instead of more precise .ihx extension. This change has ripple effects to many build- related scripts and programs and could cause some short-term problems. * configs/stm3240g-eval/, arch/arm/src/stm32/up_allocateheap.c: Add support for the 16-mbit SRAM on-board the STM3240G-EVAL board. * drivers/usbdev/cdcacm.c and include/nuttx/usbdev/cdcacm.h: The CDC/ACM driver can now be dynamically connected and disconnected from the host under software control. * include/nuttx/arch.h, configs/stm3240g-eval/src/up_cxxinitialize.c, and configs/stm3240g-eval/src/up_cxxinitialize.c: Add support for C++ static initializers. * net/setsockopt.c, net/getsockopt.c, net/bind.c, net/socket.c: Add more low level, thread-independent socket interfaces for use within the OS. Some of these are currently used by the FTP controlling terminal. More will be used to support the NFS file system currenly underwork. * include/nuttx/net/: Major re-organization of networking headerf files. Moved all non-standard, NuttX-specific header files from include/net and include/nuttx into include/nuttx/net. * arch/mips/src/pic32mx/pic32mx_usbdev.c: The PIC32 USB driver now appears to be fully functional. * configs/sure-pic32mx/usbnsh and configs/sure-pic32mx/src: Add support for NSH using only USB serial I/O to support the console. This is useful on devices that have USB, but no serial port. * arch/mips/src/pic32mx/pic32mx_spi.c: Add a PIC32 SPI driver. Initial checkin is primitive, incomplete (lacks interrupt logic), and untested. * configs/pic32-startkit/nsh: Completed verification of the PIC32 Ethernet Starter Kit port. Added and verified the NuttShell (NSH) on the PIC32 Ethernet Starter Kit. I can now (finally) claim to have complete the basic port to this board. * configs/pic32-startkit/nsh/up_usbdev, up_nsh.c, and up_usbterm.c: Verified the USB (device) driver on the PIC32 Ethernet Starter Kit. * arch/mips/src/pic32mx/pic32mx_ethernet.c: Verified the PIC32 Ethernet driver on the PIC32 Starter Kit. Status: It is occasionally functional but not stable enough for use. * arch/arm/include/stm32, arch/arm/src/stm32: Add general support for the STM32 F2 family. Contributed by Gary Teravskis, * configs/stm3220g-eval: Add support for the STMicro STM3220G-EVAL board. Contributed by Gary Teravskis, 6.17 2012-04-14 Gregory Nutt * configs/sure-pic32mx: Add support for the Sure DB-DP11212 PIC32 General Purpose Demo Board * arch/arm/src/stm32/stm32_usbhost.c/.h: Add files that will (eventually) hold an STM32 USB host driver (the initial check-in is the NuttX LPC17 USB host driver with name changes only). * arch/arm/src/stm32/chip/stm32_otgfs.h: STM32 USB OTG FS register definitions (not complete on initial check-in). * net/connect.c: Add another low level, thread-independent socket interface for use within the OS. * arch/mips/src/pic32mx/pic32mx_ethernet.c: The PIC32 Ethernet driver is now stable on the PIC32 Starter Kit. * configs/pic32-starterkit/nsh2: Add a PIC32 Ethernet Starter Kit NSH configuration that has no serial console; all interaction is done via Telnet. * net/netdev_sem.c: Correct a deadlock condition by making a seamphore recursive. To my knowledge this deadlock only occurs when running the NSH command ifconfig over Telnet. In that case the function netdev_foreach takes the network device semaphore, but so does the telnet logic causing the deadlock. * arch/arm/src/stm32/stm32_pm*.c: Add basic STM32 power management logic that will eventually be used to implement low power states. * arch/arm/src/stm32/stm32f*0xx_rcc.c: In order to use CAN2, both CAN1 and CAN2 clocking must be enabled. * arch/mips/src/pic32mx/picm32mx-usbdev.c: Several stall-related fixes so that the USB device driver can used the mass storage class (which does a LOT of stalling as part of its normal protocol). The PIC32 USB Mass Storage device is, however, still non-functional when debug is OFF. * include/nuttx/fs: Move all file-system related files from include/nuttx to include/nuttx/fs. * include/nuttx/serial: Move all serial-driver related files from include/nuttx to include/nuttx/serial. * include/nuttx/clock.h and sched/clock_initialize.c: Add a new OS interface called clock_sychronize() that can be used to re-synchronize the NuttX system time with a hardware RTC. This function is called normally at power up but may also need to be called when recovering from certain low-power usage states where the system time is no longer accurate. * arch/arm/src/calypso and arch/arm/include/calypso: Support for the TI "Calypso" phone processor. Contributed by Denis Carilki and includes the work of Denis, Alan Carvalho de Assis, and Stefan Richter. * configs/compal_e88 and configs/compal_e99: Support for Compal e88 and e99 phones Contributed by Denis Carilki and includes the work of Denis, Alan Carvalho de Assis, and Stefan Richter. * arch/arm/src/lpc17xx: Several fixes for error that have crept in for the LPC17xx DAC. Contributed by by Lzyy. * graphics/nxconsole: Add a character driver that can be used as a console output device for text output (still under development on initial check-in). * graphics/nxmu: Fix several compilation errors that have crept into the multi- user NX server because of lack of use. * graphics/nxconsole: The NX text console is basically function (in multi- user NX mode only). * arch/arm/src/stm32/stm32_i2c.c: Correct a bug in the STM32 I2C driver. The behavior of I2C status bits seems to be different between F1 and F4. * configs/stm3210e-eval/nxconsole: New STM32 F1 configuration that runs the NuttShell (NSH) within an NX window. * graphics/nxconsole/nxcon_sem.c: Add protection from re-entrance with debug is enabled. * include/nuttx/ascii.h and vt100.h: Header files to centralize ASCII and VT100 escape sequence definitions. * graphics/nxconsole/nxcon_vt100.c: Add add framework to support VT100 escape sequences in NxConsole. * fs/fs_read.c: Fix read() return value for attempt to read from write-only file or device. Was returning EBADF, should return EACCES. * graphics/nxconsole.c: NxConsole now supports backspace and a cursor. * Kconfig and arch/sim/Kconfig: Beginnings of support for a NuttX configuration tool. Currently using the kconfig parser 'kconfig-frontend' available at http://ymorin.is-a-geek.org/projects/kconfig-frontends (version 3.3.0-1 is also available in the NuttX SVN at trunk/misc/tools/kconfig-frontends-3.3.0-1.tar.gz). Contributed by Lzyy. * */Kconfig: Added skeleton Kconfig files to all directories that may need them. * include/nuttx/math.h: Moved include/math.h to include/nuttx/math.h because it conflicts too often with the system math.h (and people aren't inclined to read the documentation on how to handle this). Now, if CONFIG_ARCH_MATH_H=y is defined, the top-level makefile will copy the redirecting math.h header file from include/nuttx/math.h to include/math.h. So for the architectures that define CONFIG_ARCH_MATH_H=y, include/math.h will be in place as it was before; for the architectures that don't select CONFIG_ARCH_MATH_H, the redirecting math.h header file will stay out-of-the-way in include/nuttx/. * Kconfig, sched/Kconfig, lib/Kconfig, libxx/Kconfig, arch/sim/Kconfig, drivers/Kconfig, drivers/mtd/Kconfig, drivers/input/Kconfig drivers/analog/Kconfig, drivers/lcd/Kconfig: Updated kernel configuration support provided by Lzyy. * Kconfig: Many more Kconfig updates (no longer tracking in the ChangeLog) * arch/arm/src/Makefile, arch/x86/src/Makefile, arch/avr/src/Makefile, arch/mips/src/Makefile, arch/sim/src/Makefile, arch/hc/src/Makefile, arch/sh/src/Makefile: The libgcc.a in newer versions of GCC now have an dependency on an external implementation of abort(). This required modification to the Makefiles that do the final link: Now libgcc.a must be included within the group of libraries that are search recursively. * arch/arm/srm/stm32/stm32_otgfsdev.c: A USB OTG FS device-side driver for the STM32 F4 (and maybe F2 and F1 connectivity line). * tools/cmpconfig.c: A tool for comparing two configuration files. * include/nuttx/usb/usbdev.h, drivers/usbdev/*, arch/*/src/*/*usb*.c: Extend the USB device side interface so that EP0 OUT data can be passed with OUT SETUP requests. * include/nuttx/watchdog.h: Add the definition of a standard watchdog driver interface. * drivers/watchdog.c: The "upper half" watchdog timer driver. 6.18 2012-05-19 Gregory Nutt * Kconfig: Continued Kconfig file updates (no longer tracking on a per-file basis in the ChangeLog) * arch/arm/src/stm32/stm32_iwdog.c and stm32_wwdog.c: Add the STM32 IWDG and WWDIG watchdog timer driver. * configs/stm3240g-eval/src/up_lcd.c: Add LCD from for the STM3240G-EVAL (the initial check-in is just a stm3210e-eval driver with renaming). * sched/sched_setscheduler.c: Correct successful return value (Contributed by Richard Cochran). * include/fcntl.h and lib/stdio: Ignore CONFIG_STDIO_LINEBUFFER is the file was opened in binary mode. * lib/stdio/lib_fopen.c: Correct an error in parsing open mode string. The plus sign may not appear right after the basic mode. For example, "r+", "rb+", and "r+b" are all valid open strings and mean the same thing. * lib/stdio/lib_fopen.c: Correct return errno value from f_open() and f_fdopen() if the open mode string is invalid. * drivers/serial/serial.c: Do not disable Rx interrupts on each byte. Rather, only disable Rx interrupts when the Rx ring buffer may be empty. * include/nuttx/usb/audio.h: USB Audio 1.0 definitions (in progress). * arch/arm/src/stm32/stm32fxx_dma.c: STM32 F4 DMA now supports circular buffer mode (contributed by Mike Smith) * arch/arm/src/stm32/stm32_serial.c: The serial driver can now support Rx DMA into a circular buffer (contributed by Mike Smith) * configs/pic32mx7mmb: Beginning of a configuration for the Mikroelektronka PIC32MX7 Multimedia Board (MMB). * net/recvfrom.c: Fix a compilation problem. Some UDP logic was conditioned on TCP, not UDP. * drivers/usbdev/cdcacm.c: Fix an infinite loop that occurs when the serial device is unregisters. * arch/arm/src/stm32/stm32_otgfs.c: The driver needs to reset the software (in order to flush the requests) and to disable the software connection when the device is unregistered. * include/sys/prctl.h, sched/prctl.c, include/pthread.h: Add interfaces to support getting and setting of the thread or task name. * configs/ubw32: Added a configuration to support the Sparkfun UBW32 PIC32 board. * configs/ubw32/nsh: Added an NSH configuration for the Sparkfun UBW32 PIC32 board. * configs/ubw32/up_buttons.c: Added button support for Bit Whacker board. * configs/stm3240g-eval/nxconsole: Added a configuration to run the NSH shell in an NX window for the STM3240G-EVAL board. * include/cxx/cunistd: C++ header file to make sure that everything in unistd.h is in the std:: namespace. * configs/sim/nxwm: Added a configuration for testing the NuttX Window Manager (NxWM) * fs/fs_fcntl.h: On success, always returned OK. However, some fcntl commands require returning other values on success. * Various files. Fix warnings about variables that were initialized by not used. * configs/sim/*/defconfig: Changes to build a 32-bit simulation on a 32-bit platform did not make into all of the Make.defs files. * graphics/nxmu/nx_move.c: Wrong opcode was being used in the server message; Also there was an error in the offset calculation. * graphics/nxglib/fb/nxglib_moverectangle.c: Offset argument is really a position, not an offset. * graphics/nxtk/nxtk_drawframe.c: Framed windows are now drawn in three colors (instead of just two). * drivers/input/stmpe811_*: Added a driver to support the STMicro STMPE811 IO Expander and touchscreen driver. * configs/stm3240g-eval/nxwm: Added to configuration for testing the NxWM window manager on the STM3240G-EVAL board. * graphics/nxtk/nxtk_toolbarbounds.c: Added an interface to get the toolbar bounding box. * graphics/nxtk/nxtk_drawframe.c: Fix an error in drawing the window frame. * NX, NxConsole: Replace CONFIG_NXCONSOLE_NOGETRUN to CONFIG_LCD_GETRUN. The inability to read from the LCD is a property of the LCD, not of NxConsole. Then add CONFIG_NX_WRITEONLY which is the more generic way of saying that no NX component should try to read from the underlying graphic device (LCD or other). * configs/stm3240g-eval/src/up_stmpe811.c: Add board-specific support for the the STMPE811 I/O expander on the STM3240G-EVAL board. Verfied that the STM3240G-EVAL touchscreen is now fully functional. * include/cxx/cfcntl: Added std:: header file. * graphics/nxbe/nxbe_filltrapezoid.c and graphics/nxglib/fb/nxglib_filltrapezoid.c: Fix several errors in the trapezoid fill logic. * include/nuttx/input/touchscreen.h, configs/hymini-stm32, configs/stm3240g-evel, * configs/sam3u-ek, configs/sim, arch/sim/src/up_touchscreen.c, and apps/examples/touchscreen: Standardize the board-specific, touchscreen initialization interfaces. * drivers/input/stmpe811_base.c and configs/stm3240g-eval: The STMPE811-based touchscreen seems to work better with edge (vs. level) interrupts * drivers/input/stmpe811_tsc.c: Fix some status checks so that the touchscreen interrupt handling logic does not read data if the fifo is not at the threshold level. * include/nuttx/wqueue.h: Add macro work_available() to determine if the previously scheduled work has completed. * drivers/stmpe811_tsc.c: Correct errors: (1) Since all interrupt logic is done on the worker thread, disabling interrupts does not provide protected; Need to disable pre-emption. (2) Fix handling of touch ID and (2) add some logic to prevent certain kinds of data overrun. * include/nx/nxtk.h and graphics/nx/nxtk/nxtk.h: Move setting of configuration defaults from the internal header file to a place where other logic can use the defaults. * graphics/nxtk/nxtk_events.c: Fixed an important but in the logic that translates the mouse/touchscreen position data for framed windows and toolbars. * drivers/input/stmpe811_tsc.c, tsc2007.c, and ads7843e.c: Need to keep track of when if positional data is valid. When the touch is released, the X/Y position of the release must be the same as the X/Y position of the last touch (se that the release occurs in the same window as the last touch). * graphics/nxtk/nxtk_events.c: Fix an error in mouse/touchscreen input logic: Was autoraising the window AFTER processing the mouse press. This raises havoc if the result of processing the mouse click was to raise some other window! * graphics/nxtk/nxtk_events.c: I had to disable the whole autoraise feature for multi-user case because it does not work correctly. In a scenario where (1) there are multiple queued touchscreen events for the same window and (2) the result of the first input was to switch windows, then the autoraise implementation will cause the window to revert to the previous window. Not good behavior. * sched/sched_mergepending.c: Add task switching instrumentation. There is a case here where instrumentation was missing. Contributed by Petri Tanskanen. * CONFIG_STMPE811_THRESHX, CONFIG_STMPE811_THRESHX, and drivers/stmpe811_tsc.c: Add some thresholding controls to all slow down processing of touchscreen samples. This is a problem with NX in multi-user mode: touchscreen data gets sent via a message and when the message queue gets full the sender blocks and touch events are lost. Basic data overrun. The badly effects touchscreen human factors. * include/sched.h: Fix a typo (missing semicolon) in prototype of on_exit(); * sched/on_exit.c and include/nuttx/sched.h: Fix some old typos that caused compilation errors when CONFIG_SCHED_ONEXIT is defined. * configs/stm3240g-eval/nxwm/defconfig: The default NxWM now uses the STMPE811 touchscreen. * include/cxx/csched: Added * graphic/nxmu/nxmu_sendserver.c, nxmu_sendwindow.c, and nxmu_sendclient.c: Refactor NX messaging logic in preparation for a new message control feature. * graphics/nxtk, graphics/nxmu, include/nuttx/nx: Add a new window communication to support blocking and flushing of client window messages. If there are stale, queue window messages at the time that a window is destroyed, very bad things happen. 6.19 2012-06-15 Gregory Nutt * graphics/nxconsole/nxcon_kbdin.c: If selected, the NxConsole will take input from the NX keyboard input callback. If this option is set, then the interface nxcon_kdbin() is enabled. That interface may be driven by window callback functions so that keyboard input *only* goes to the top window. If CONFIG_NXCONSOLE_NXKBDIN is not selected, then the NxConsole will receive its input from stdin (/dev/console). This works great but cannot be shared between different windows. Chaos will ensue if you try to support multiple NxConsole windows without CONFIG_NXCONSOLE_NXKBDIN * graphics/nxmu/nx_kbdin.c: Fix pointer argument. This is a error introduced in changes leading up to the 6.18 release. This error will cause crashes or perhaps simply not work when you try to handle window keyboard data in multi-user mode. * graphics/nxconsole/nxcon_kdbind.c: Fixed unmatched sem_wait and sem_post. Fix some conditional compilation that included a few too many lines of code. * drivers/input/stmpe811_tsc.c and stmpe811.h: Add a timeout to catch missed pen up events. Now the STM3240G-EVAL touchscreen works very smoothly. * configs/stm3240g-eval/nxwm/defconfig: Enable support for NxConsole keyboard input. Increasing spacing of icons. * configs/stm3240g-eval/nxwm/defconfig: Use a larger font for the calculator. * include/nuttx/lcd/ssd1289.h, drivers/lcd/ssd1289.c and .h: Generic LCD driver for LCDs based on the Solomon Systech SSD1289 LCD driver. This of this as a template for an LCD driver that will have to be cusomized for your particular LCD hardware. * configs/stm32f4discovery/src/up_extmem.c and up_ssd1289.c: Add support to STM32F4Discovery for than an external, SSD1289-based LCD. * configs/stm32f4discovery/nxlines: Add an STM32F4Discovery configuration to thest the SSD1289-based LCD. * configs/stm3240g-eval/src: Add USB GPIO initialization logic needed in board-specific boot logic. * configs/stm32f4discovery/src: Add USB GPIO initialization logic needed in board-specific boot logic. * drivers/usbdev/pl2303.c and cdcacm.c: Fix the request size used for sending packets. It was not using the maximum request size, but instead the previous request size. As a result, packets get smaller, and smaller, and ... This is an important USB serial fix. * arch/arc/src/stm32_otgfsdev.c: Bug fix: Don't process TXFE if we have already processed an XFRC interrupt. We have already done what needs to done in that case. * arch/arc/src/stm32_otgfsdev.c: Fixed some status settings in queuing of write messages. Added a "hack" to work around missing TxFIFO empty interrupts. The hack is basically to poll for space in the TxFIFO instead of of setting up the interrupt. * arch/arm/src/stm32/stm32f2* and chip/stm32f2*: Update all STM32 F2 file so that they are equivalent to F4 files. This is kind of a maintenance nightmare. * configs/stm3220g-eval/: Update existing configurations to the same level as the corresponding STM3240G-EVAL configurations. This adds FSMC SRAM, touchscreen, and LCD support. * configs/stm3220g-eval/: Add a NxWM configuration for the STM3220G-EVAL. * stmpe11*: Fix a massive naming problem. All references to STMPE11 should be STMPE812. * arch/arm/src/stm32/stm32_otgfsdev.c: Need to enabled USB reset interrupt (contributed by Erik Van Der Zalm). * sched/sleep.c: Fix the return value from sleep(). The correct behavior is to return the number of unwaited seconds; the implementation was always returning zero. * sched/usleep.c and include/unistd.h: Was a void function, but should return 0 on success. usleep() needs to check the return value from sigtimedwait(). sigtimewait() returns the signal number that awakened it and an error (EAGAIN) if the timeout expired (normal case). * sched/sig_timedwait.c: Fix sigtimedwait() return value. On a timeout, it was setting the 8-bit si_signo field to -1 and eded up reported successfully awakened by signal 255! Now detects the timeout and errors -1 with errno == EGAIN. If sigtimedwait() is awakened by an unblocked signal, but it is not one of the signals in the waited-for set, it will return -1 with errno == EINTR. * arch/arm/src/stm32_i2c.c: Fix STM32 F2 I2C. It is apparently bug-for-bug compatible with the F4 and needs the same work-around for the missing BTF signal that was needed for the F4. * drivers/lcd/ssd1289.*: Fix some of the initial register settings. * configs/stm32f4discovery/src/up_ssd1289.c: FSMC address bit 16 is used to distinguish command and data. But FSMC address bits 0-24 correspond to ARM address bits 1-25, se we need to set bit 17 in order generate output on FSMC_A16. * arch/arm/src/lm3s/lm3s_epi.h and lm3s_timer.h: LM3S header files (contributed by Max Neklyudov). * arch/arm/src/stm32/stm32_irq.c: Some of the interrupt priorities were not be initialized (F2 and F4 only). Thus, the very high numbered interrupts (like UART6) and cause nested interrupts. This leads to some very difficult to debug crashes. Fix contributed by Mike Smith. * arch/mips/src/pic32/pic32_head.S and pic32_config.h and configs/pic32mx7mmb/include/board.h: Extended PIC32 device configuration capabilities and change board.h to support unique clocking requirements of the Mikroelektronika PIC32MX7 MMB. That board now works! * configs/pic32mx7mmb/nsh: Added and verify a NuttShell configuration for the Mikroelektronika PIC32MX7 MMB board. * arch/mips/pic32/pic32mx-ethernet.c: Fix logic that guesses PHY address; the search loop missed the PHY address needed by the Mikroelektronika PIC32MX7 MMB board. * configs/pic32mx7mmb/nsh: Configuration now supports a network by default. * configs/pic32mx7mmb/src: Add support for the MMC/SD slot on board the Mikroelektronika PIC32MX7 MMB board (not working on initial check-in). * arch/mips/src/pic32/pic32mx-spi.c: Add support for very low-level, register access debug output. * configs//pic32mx7mmb/include/board.h: Reduced peripheral clock to 4MHz to match other PIC32 configurations. * configs/pic32mx7mmb/src/up_nsh.c: SD card needs to operate in SPI mode 2. * configs/pic32mx7mmb/nsh/defconfig: MMC/SD card support is now enabled by default in the PIC32MX7 MMB board configuration. * configs/pic32mx7mmb/nsh/defconfig: Verified the USB Mass Storage Class (MSC) using MMC/SD card as the logical unit. Updated the default PIC32MX7 MMB board configuration so that USB and the mass storage class are enabled by default. * drivers/lcd/mio283qt2.c and include/nuttx/lcd/mio283qt2.h: Add generic support for the MIO283QT2 LCD. * configs/pic32mx7mmb/src/up_mio283qt2.c: Add support for the MIO283QT2 LCD on the PIC32MX7 MMB board. * configs/pic32mx7mmb/src/up_touchscreen.c: Add an ADC-based touchscreen driver for the PIC32MX7 MMB board. Kind of works, but needs more verification and tuning. * arch/mips/src/common/up_idle.c: Strange but important fix. For some still- unknown reason, interrupts are left in an unhealthy state in the IDLE when the work queue is enabled. This is partially because some interrupt related logic is not built in that case. Simply disabling then re- enabling interrupts restores the proper state. * graphics/nxglib/lcd/nxglib_filltrapezoid.c and fb/nxglib_filltrapezoid.c: Fix an error when the trapezoid is only 1 line high. In this case, a divide by zero error would occur. The fix is to draw the 1 line high trapezoid as a run. * drivers/usbdev/pl2303.c: Fix a cut'n'paste error that snuck into the PL2303 emulation driver several months back. 6.20 2012-07-12 Gregory Nutt * configs/stm3210e-eval/src and arch/arm/src/stm32/: Add beginnings of power management support for the STM32 and the STM3210E-EVAL board, in particular. * Documentation/NfsHowTo.html: Add a How-To document for the new NFS client feature. * arch/mips/include/pic32mx and arch/mips/src/pic32mx: Add support for the PIC32MX1 and PIC32MX2 families. * configs/mirtoo: Add a board configuration to support the DTX1-4000L "Mirtoo" module from http://www.dimitech.com/ * tools/pic32mx: All of the duplicate directories containing the same same PIC32 tools were move to this single location. * configs/mirtoo: The basic Mirtoo port is now functional. * configs/mirtoo/ostest: Added support for the microchipOpen toolchain (see http://sourceforge.net/projects/microchipopen/). * configs/mirtoo/nsh: Added a NuttShell (NSH) configuration for the Mirtoo module. * configs/mirtoo/scripts: Move all Mirtoo linker scripts to a common directory. * arch/mips/src/pic32mx/pic32mx-gpio.c: All digital inputs were being configured as outputs. This is a *critical* bug fix and needs to be incorporated by any PIC32 users. * drivers/mtd/sst25.c: Added a driver for the SST 25 SPI-based FLASH parts. * configs/mirtoo/src/up_nsh.c: The Mirtoo NSH configuration can now mount the SST 25 devices so that it can be used for a FAT file system. There are are, however, some NSH memory usage issues if this configuration enabled now. Some tuning is still needed. * configs/mirtoo/nxffs: Add an alternative NSH configure for the Mirtoo module for testing the on-module SST 25 chip using the NXFFS file system. * arch/arm/src/lpc43xx and arch/arm/include/lpc43xx: The NXP LPC43xx port is slowly evolving in these directories. * configs/stm3210e-eval/pm: Add a new configuration for testing STM32 power management. * configs/stm3210e-eval/scripts: Moved all of the duplicate ST3210-EVAL linker scripts into one set of linker scripts at this location. * configs/stm3210e-eval/src/up_buttons.c, up_lcd.c, and up_pm.c: New logic for testing STM32 power management. * configs/lincoln60: Add a configuration to support the Micromint Lincoln60 board. * configs/ekk-lm3s3b96: Add a configuration to support the TI/Stellaris EKK-LM3S3B96 development board. Contributed by Jose Pablo Rojas V. * arch/arm/src/lpc43xx/chip: Created header files for *all* (really) lpc43xx registers and all bit-fields. * configs/lpc4330-xplorer: Added a configuration for the NXP LPC43XX Xplorer board. This is just to facilitate testing of the LPC43xx port but will, with any luck, become proper board support for that board. * arch/arm/src/lm3s/lm3s_syscontrol.c: Fix an optimization related problem by adding a volatile qualifier to a timing loop. Oddly, the consequence of the bug is that when debug was off, the LM3S platform too a long time to boot. It now boots rapidly whether debug is on or off. * arch/*/include/limits.h: Change all values in all limits.h for all architectures to signed decimal; the hex values were not sign extending appropriate in most uses (reported by Lorenz Meier). * arch/arm/src/stm32/chip/stm32f103/7vc_pinmap: Fix typographical error in two pinmap definition files. * lib/net/lib_inetntoa.c: Fix typographical error that cause compilation failure on platforms that do not support passing of structures as parameters. * arch/arm/*/lpc43xx and configs/lpc4330-xplorer and code complete and ready for testing. Hopefully, verified LPC43xx support will appear in NuttX-6.20. * include/nuttx/stdarg.h: If CONFIG_ARCH_STDARG_H=y is defined, the top-level makefile will copy the generic (GCC-only) stdarg.h header file from include/nuttx/stdarg.h to include/stdarg.h. So for the architectures that cannot use their GCC toolchain's stdarg.h file, they can use this alternative by defining CONFIG_ARCH_STDARG_H=y. If CONFIG_ARCH_STDARG_H, is not defined, then the redirecting stdarg.h header file will stay out-of-the-way in include/nuttx/. * configs/lpc4330-xplorer/nsh: Add an NSH configuration for the LPC4330 Xplorer board. 6.21 2012-08-25 Gregory Nutt * configs/lpc4330-xplorer/up_nsh.c: Add support for a basic SPIFI block driver for use by NSH. Does not work! Crashes on first SPIFI write. * configs/lpc4330-xplorer/*/defconfig: Calibrate delay loops (this is based on the current "slow" 72MHz M4 clock and will need to be re-calibrated when this is increased). * configs/stm3220g-eval/include/board.h and configs/stm3240g-eval/include/board.h: The SDIOCLK frequency in the F2 and F4 derives for PLL48CLK and not HCLK so that the SDIOCLK input frequency should always be 48MHz. * sched/os_internal.h, sched_setupidlefiles.c, sched_setuptaskfiles.c, and sched_setupidlefiles.c: Detangle some conditional compilation. Allow for a perverse configuration that has socket descriptors and streams but no file descriptors (sure, why not?). * sched/: Stylistic clean-up of all files. Some of these files are pretty old and do not follow current NuttX coding standards in detail. * fs/: More stylistic file clean-up. * mm/: More stylistic file clean-up. * drivers/ and drivers/serial/: More stylistic file clean-up. * arch/arm/src/lpc43xx/lpc43_clockconfig.c: Fix PLL1 bit manipulation logic. Critical bugfix! This would often cause the LPC43xx to fail to boot. * arch/arm/src/lpc43xx/lpc43_rgu.c: The soft reset logic called from the beginning of __start seems cause problems. A magic delay seems to improve the logic some. But I suspect that real fix is to get rid of all of the soft reset logic. This would also be a critical bugfix if I believed that it really fixed all of the issues. * arch/arm/src/lpc43xx/chip/lpc43_cgu.h: Fix a bit mask in the PLL1 control register. Critical bugfix. * arch/arm/src/lpc43xx/lpc43_clockconfig.c and configs/lpc4330-xplorer/include/board.h: Implement PLL1 ramp-up logic; Now the LPC43xx is running at 204MHz. * configs/lpc4330-xplorer/*/defconfig: Re-calibrated delay loops using the 204MHz clock. The LPC43xx ripping rips! This calibration was performed with symbols enabled and all optimization disabled. It will need to be better recalibrated again down the road. * arch/arm/src/stm32/stm32_exti.c: Renamed to rch/arm/src/stm32/stm32_exti_gpio.c to make a little room in the file name space. * arch/arm/src/stm32/stm32_exti_alarm.c: Add initial logic to attached the RTC alarm EXTI interrupt. This is work be performed mostly by Diego Sanchez. * include/: More stylistic file clean-up. * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: Add logic to configure and initialize the SPIFI device (does not yet work). * configs/lpc4330-xplorer/include/board.h: Reduce SPI SCLK value. * arch/arm/src/lpc43xx/lpc43_spifi.c, lpc43_spifi.h, and chip/lpc43_spifi.h: Logic completely redesigned. It now creates an MTD driver to access SPIFI... but the driver still does not work. * arch/arm/src/stm32 and arch/arm/include/stm32: Make name of RTC ALARM interrupt common on STM32 F1,2,4 * arch/arm/src/stm32 and arch/arm/include/stm32: Add support for the STM32F100x "Value Line" devices. This includes changes to stm32F10xx_rcc.c that add the ability to run the chip off the internal oscillator. There is no open board configuration for this part yet (the STM32VLDiscovery would be a candidate). Contributed by Mike Smith. * arch/arm/src/stm32: Fixed typos in conditional compilation in the CAN and DMA and some pin configuration. This would have caused problems for STM32 F107xx. Typos noted by Mike Smith. * arch/arm/src/lpc43xx/lpc43_serial.c: Add support for certain RS-485 features * lib/termios/lib_cfsetispeed.c, lib_cfsetospeed.c, lib_tcflush.c: Add simple implementations of cfsetispeed(), cfsetospeed(), and tcflush(). * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: Add APIs to support setting non-standard BAUD values not supported by POSIX termios. These are non-standard interfaces but have a precedence: There are similar interfaces in AIX. * include/sys/str_tty.h, lib/lib_setspeed.c, lib_getspeed.c, and lib_resetspeed.c: Sigh... removed. We don't need any more almost standard interfaces! (SVN revision 4968 if you want the short-lived code). * include/termios.h and lib/termios/*: Open the existing, standard termios interfaces to permit some non-standard baud settings. The new termios definitions still supports the POSIX standard except that it does not strictly enforce baud rate settings, permitting some non-portable, but useful baud rate settings (this is what the short-lived AIX-like interfaces would have accomplished as well). * include/termios.h and lib/termios/*: Redesigned yet again (this is getting painful. NuttX now supports the BOTHER baud setting just as Linux does. termios Bxxx definitions are again encoded; cf[set|get][o|i]speed now deal with only the encoded values. If the encoded baud is set to BOTHER, then the values in the (non- standard) c_ispeed and c_ospeed baud values may be accessed directly. * arch/arm/src/stm32/stm32_serial.c: Add minimal termios support for the STM32 (BOTHER style baud settings only). Contributed by Mike Smith. * configs/lpc4343-xplorer/src: Clean up SPIFI-library based build to that it actually works. * arch/arm/src/lpc43xx/lpc43_spifi.c: Add support for verification to writes. Add debug option to dump buffers. Several bugfixes... almost works. * include/termios.h, lib/termios/*, and arch/arm/src/stm32/stm32_serial.c: : BOTHER is gone again. * arch/arm/src/stm32/stm32_sdio.c and chip/stm32f20xx_pinmap.h: STM32 F2 SDIO fixes from Gary Teravskis and Scott Rondestvedt. * include/termios.h and lib/termios/*: Replace cfsetispeed and cfsetospeed with cfsetspeed (with definitions for the input/outputs in termios.h). * configs/stm32f4discovery/src and configs/stm32f4discovery/pm: Add a power management configuration for the STM32F4Discovery and supporting logic. This check-in also includes some fixes for the F4 RTC alarm logic. * drivers/input/pga11x.c and include/nuttx/input/pga11x.h: Add support for the TI PGA112/3/6/7 amplifier/multiplexer parts. * configs/mirtoo/README.txt, nsh/defconfig, and nxffs/defconfig: Add support for the PGA117 on the Mirtoo module. * drivers/analog/pga11x.c and include/nuttx/analog/pga11x.h: These belong in the analog subdirectories, not input. * configs/compal_e99/src/ssd1783.c and /ssd1783.h: Drivers for the SSD1783 LCD found in the Motorola C155 telephone. The driver is specific to the C155 because it uses the uwire transport. Contributed by Denis Carilki and Alan Carvalho de Assis. * drivers/power/pm_changestate.c. Correct a case where interrupts were not being re-enabled. Found by Diego Sanchez. * configs/mirtoo/nxffs/defconfig: This Mirtoo NXFFS configuration now uses the open Pinguino toolchain by default. This is necessary because the free C32 toolchain does not support any optimization and the unoptimized NXFFS image hits the PIC32MX2 FLASH size (128K). There is plenty of room to grow using the Pinguino toolchain with -O2 optimization. * configs/mirtoo/src/up_adc.c. This is just a stub for now, but this is where Mirtoo ADC logic will eventually need to go. * arch/mips/src/pic32mx/pic32mx-gpio.c: Now supports the PIC32MX1/2 ANSEL IOPORT register. * lib/string/lib_memchr.c: Add support for memchr() (contributed by Mike Smith) * lib/string/lib_memccpy.c: Add support for memccpy() * arch/arm/src/lpc17xx/lpc17_serial.c: Now supports ioctl commands to change the baud using tcsetattr() (contributed by Chris Taglia). * arch/*/src/*_serial.c: Fix ioctl method return values. These methods should return a negated errno value; they should not set the errno variable. * sched/on_exit.c, sched/task_exithook.c, and include/nuttx/sched.c: Add support for multiple registered on_exit() functions if CONFIG_SCHED_ONEXIT_MAX is defined. * drivers/syslog/ramlog.c: Move the RAM SYSLOG device into drivers/syslog so that it will be in the same directory as some new SYSLOGing devices in the works. * include/nuttx/syslog.h and drivers/syslog/ramlog.c: The SYSLOG putc function now has a common name that is independent of the device that provides the SYSLOG. * include/nuttx/syslog.h and drivers/syslog/syslog.c: This is a new, generic SYSLOG device that can redirect debug output to any character device or file. So you can log debug output to a file or you can put the console on /dev/ttyS0 and the debug output on /dev/ttyS1. * arch/arm/src/lpc43xxl/lpc43_spifi.c: Correct an addressing error in the LPC43 SPIFI MTD driver * drivers/syslog/syslog.c and fs/fs_syslog.c: Moved the generic syslog logic from drivers/syslog to fs/ where is belongs. Especially after realizing that the syslog logic is going to have to some internal FS operations in order to realize a totally thread-independent SYSLOG interface. * arch/arm/src/stm32/stm32*_rcc.c and .h: If CONFIG_PM is defined, add a function called stm32_clockenable() that can be used by PM logic to re-start the PLL after re-awakening from deep sleep modes. * fs/fs_foreachinode.c and fs/fs_foreachmountpoint.c: Add logic to traverse inodes and mountpoints in the NuttX pseudo-file system. * fs/fat/fs_fat32.c: Max. filename length reported by statfs() was wrong if FAT long file names were enabled. * lib/stdio/lib_libvsprintf.c: Fieldwidth and justification were not supported for the %s format. As a result, %s, %12s, and %-12s all produced the same output. * lib/stdio/lib_libdtoa.c: Fix several issues with presenting floating point numbers (conversions are fine, but presentation was bad). This is a critical bug fix if you use printf or sprintf to deal with floating point numbers. * lib/stdio/lib_libdtoa.c and lib_libvsprintf.c: Correct some floating point options. * arch/arm/lpc43xx/lpc43_usb0dev.c: Add framework for development of an USB0, device-side driver for the LPC43XX. The initial check-in, however, is simply for the LPC31xx driver with name changes. The LPC31xx has the same USB IP, but will require some additional initialization (and lots of testing) before it can be used with the LPC43xx. * nuttx/Documentation/NuttShell.html: Added a section covering ways to customize the behavior of NSH. * arch/arm/src/stm32/chip/stm32f1*_pinmap.h: STM32 CAN TX/RX pins reversed; inconsistent conditional compilation. Reported by Max Holtzberg. * arch/arm/*/stm32: Add support for STM32 F107 "Connectivity Line" Ethernet (contributed by Max Holtzberg). * configs/olimex-stm32-p107: Add board support for the Olimiex STM32-P107 board (contributed by Max Holtzberg). * arch/arm/src/stm32/stm32f2xx_dma.c, stm32f4xx_dma.c, stm32_serial.c, and stm32_spic.c: DMA priority was getting zeroed by STM32 F2/F4 DMA drivers so that all DMAs ran at the lowest priority. * configs/stm3240g-eval/include/board.h and configs/stm3220: Drop SD card frequency from 24 to 16 MHz. Apparently 24 MHz is too fast for the board. This (plus the change to the STM32 DMA (above) fixes SDIO DMA on the STM3240G-EVAL (and probably STM3220G-EVAL -- untested). * arch/arm/src/stm32/stm32f2xx_dma.c and stm32f4xx_dma.c: Backed out the DMA priority change just above. The reduced SD card frequency was necessary and sufficient to resolve the problem. * drivers/serial/serial.c: open, read, write, and poll methods may now abort return EINTR (or a short transfer size) if a signal is received while waiting to receive or send serial data. This behavior is required by POSIX. * include/sys/types.h: Define NULL to be (0) if __cplusplus is defined. (contributed by Mike Smith) * include/ctype.h: Remove a stray semi-colon in a definitions (Thanks Mike Smith). * configs/.../Make.defs. Fix C++ include path set-up in Make.defs file for all 8-bit AVR platforms (Thanks Richard Cochran). * lib/stdio/lib_*stream.c: Revised to handle new error return values from serial.c. * arch/arm/src/stm32/stm32_spi.c: SPI driver can now service re- initialization (Mike Smith). * tools/mkconfig.c: If CONFIG_DRAM_END is not specified, this tool will provide default definition of (CONFIG_DRAM_START + CONFIG_DRAM_SIZE) * arch/arm/src/stm32/stm32_otgfshost.c: Renamed from stm32_usbhost.c. This is nearly code complete and, with any luck, will be available in NuttX-6.21. * configs/*/defconfig: Update all defconfig files to remove syntax that is incompatible with the mconf configuration tool. * arch/arm/src/stm32/stm32_otgfshost.c: This driver now appears to be functional (although more testing is necesary). 6.22 2012-09-29 Gregory Nutt * include/semaphore.h, sched/sem_holders.c, and lib/semaphore/sem_init.c: Fix some strange (and probably wrong) list handling when CONFIG_PRIORITY_INHERITANCE and CONFIG_SEM_PREALLOCHOLDERS are defined. This list handling was probably causing errors reported by Mike Smith * sched/sched_waitpid.c: Fix a possible issue with logic logic that should be brought into a critical section (suggested by Mike Smith) * sched/sched_setuptaskfiles.c: Should be 'struct socket' not 'struct sockets'. How did this compile before? (found by Kate) * syscall/syscall.csv: Fix prototype for usleep() and prctl() (also from Kate). * arch/arm/src/lpc17xx/lpc17_ethernet.c: Conditionally elide setting PHY speed/duplex. This does not work for certain PHYs. Still some unresolved issues (also from Kate). * tools/Config.mk, Makefile, configs/*/Make.defs: Add a new Makefile fragment to de-quote certain strings from the Kconfig logic that need to be used at path segments (Richard Cochran). * arch/arm/src/stm32/stm32_usbotghost.c: The STM32 USB host driver only works with debug turned on. The problem appears to be that with debug OFF, there are more NAKs occuring in more places than before and this reveals a variety of errors. This check in improves NAK robustness for control transfers but does not resolve all of the issues. * configs/stm3220g-eval/*/defconfig: Calibrated delay loop. It had never been calibrated was way off. * sched/sem_holder.c: Add logic to handler some priority inheritance cases when sem_post() is called from an interrupt handler. The logic is clearly wrong, but it is not known if this is the cause of any known bugs. * lib/stdio/lib_perror(): Add perror(). Contributed by Kate. * lib/string/lib_strerror(): Add option CONFIG_LIBC_STRERROR that is now required to enabled strerror(). Add an option CONFIG_LIBC_STRERROR_SHORT that can be used to output shortened strings by strerror(). * arch/arm/src/stm32/stm32_usbotghost.c: Finally... the USB OTG FS appears to handle NAKing correctly. * configs/stm32f4discovery/*: Added and verifed support for USB OTG FS host on the STM32F4Discovery board. * configs/*/defconfig: Remove configuration documentation from config files. It is redundant, error-prone, and difficult to maintain. Configuration documentation is available in configs/README.txt for common configurations and in configs/*/README.txt for board and MCU- specific configurations. * configs/stm3240g-eval: Add USB host support. * sched/os_bring.c, configs/*/defconfig, tools/mkconfig.c, and others: Added configuration variable CONFIG_USER_ENTRYPOINT that may be used to change the default entry from user_start to some other symbol. Contributed by Kate. NOTE: This change does introduce a minor backward incompatibility. For example, if your application uses NSH as its start-up program, then your build will now fail because it will be unable to find "user_start". The fix for this link failure is to add the following to your configuration file: CONFIG_USER_ENTRYPOINT="nsh_main". * libs/stdio/lib_libfread.c and lib_*flush*.c: Correct a couple of error cases where the lib semaphore was not be released on error exits (thanks Ronen Vainish). Also, improved some error reporting: the generic ERROR was being used instead of the specific errno value; the errno variable was not always set correctly. * tools/mkfsdata.pl: The uIP web server CGI image making perl script was moved from apps/netutils/webserver/makefsdata to nuttx/tools/mkfsdata.pl (Part of a larger change submitted by Max Holtzberg). * configs/stm3240g-eval/script/ld.script: All of the identical ld.script files for the STM3240G-EVAL were replaced by one version in this directory. * configs/stm3240g-eval/webserver: Configuration submitted by Max Holtzberg for testing the changes to the uIP web server (see apps/ChangeLog.txt). * lib/stdio/lib_perror.c: Remove CONFIG_LIBC_PERROR_DEVNAME. What was I thinking? Arbitrary streams cannot be shared by different tasks. * tools/mksyscall.c, csvparser.c, and csvparser.h: Separate CSV parsing logic from mksyscall.c into files where it can be shared. * tools/mksymtab.c: Add a tool that can be used to convert a CSV file into a NuttX-style symbol table. * sched/work_cancel.c: Fix a bad assertion (reported by Mike Smith) * configs/stm3210e-eval/src/up_idle.c: Correct some power management compilation errors (reported by Diego Sanchez). * include/nuttx/wqueue.h, sched/work*, and others: Added logic to support a second, lower priority work queue (CONFIG_SCHED_LPWORK). * arch/arm/src/stm32/stm32_dma.c, chip/stm32*_memorymap.h: FSMC SRAM is only 16-bits wide and the SDIO DMA must be set up differently. * arch/arm/src/stm32/stm32_dma.c: Back out the 16-bit DMA change. It is incorrect. * configs/: Make use of UART4/5 vs USART4/5 consistent in all places. * Kconfig: Serial 2STOP setting must be integer 0/1, not a boolean. * lib/misc/sendfile.c and include/sys/sendfile.h: Add a Linux style sendfile() (non-standard!) * Kconfig: Refactor serial settings (moved from chip to drivers/serial). AVR "teensy" now builds with Kconfig (contributed by Richard Cochran). * Kconfig: Add configuration settings for the LPC17xx * Kconfig: Add configuration settings for the LM3S (from Richard Cochran). * Kconfig: Verify configuration settings for the STM32. This includes changes in the way that the external SRAM is configured: Define CONFIG_HEAP2_SIZE (decimal) instead of CONFIG_HEAP2_END (hex). * tools/configure.sh: Don't append the apps directory path setting if the correct setting is already in defined in the defconfig file. * fs/fat/fs_utils.c: Improperly constructed bool expression. This would cause many unnecessary writes to FLASH (Thanks Ronen Vainish). * Kconfig: Verify configuration settings for the LPC43xx. This includes some corrections to configuration variable names and defconfig settings. * Kconfig: Add and verify configuration settings for the LPC31xx. * arch/arm/src/stm32/stm32_uart.h and stm32_serial.c: Add logic to re-initialize the console UART as needed to enable DMA on the console UART (contributed by Mike Smith). * net/recvfrom.c, net/Kconfig, include/nuttx/net/uipopt.h: Remove delay after receiving data. That has historical reasons to be there (it was needed before read-ahead buffering was added), but kills performance. (Noted by Max Holtzberg). * configs/shenzhou: Add beginnings of a board configuration for the Shenzhou STM32107 board (see www.armjishu.com). Very little is in place as of this initial check-in. * QEMU: Fixes from Richard Cochran to build QEMU with Kconfig files. * arch/*/src/Makefile: Remove some old logic that was kicked off when CONFIG_BOOT_RUNFROMFLASH=y. The old logic used to use objcopy to move sections. Newer logic changes the load position of sections in the linker script. As far as I can tell, there is nothing in the source tree now that depends on the old way of doing things (if I am wrong, they will need a change to the linker script). * configs/fire-stm32v2: Configuration for the M3 Wildfire board. I don't know very much about this board other than is has an STM32F103VET6 chip, LCD, touchscreen, and ENC28J60 network. Very little is in place on the initial check-in. * configs/shenzhou: Coding for the Shenzhou board port is complete, but tested has been deferred until I get the right tools. * arch/arc/include/stm32/chip.h and arch/arm/src/stm32/chip.h: Add support for the STM32F103VET6. * fs/fs_fdopen.c: Bad check for failure to allocate memory. (Noted by Ronen Vainish). * drivers/mmcsd/mmcsd_sdio.c: If the MMC/SD driver were ever uninitialized then there would be a double release of memory (Noted by Ronen Vainish). * fs/mmap/fs_rammap.c: Fix logic error and errno check (contributed by Kate). * arch/avr/src: Fixes from AVR32 build errors that have crept in over the time; incorporated Kconfig for AVR3 (Richard Cochran). * fs/fat and include/nuttx/fs/fat.h: The FAT file system allocates memory for sector I/O buffers used to exchange data with the configured block driver. In some contexts, the block driver may require DMA-capable memory. If CONFIG_FAT_DMAMEMORY is defined, then the FAT FS will use platform-provided DMA memory allocators to allocate the block driver I/O buffers. * CONFIG_NET_ENC28J60 renamed CONFIG_ENC28J60 to be consistent in all places. * drivers/enc28j60.c, include/nuttx/net/enc28j60.h, and olimex-strp711/src/up_enc28j60.c: No longer passes IRQ number as a parameter. Instead now passes a call table to manage ENC28J60 GPIO interrupts. That is because GPIO interrupts are handled in different ways by different MCUs and some do not support IRQ numbers for GPIO interrupts. * mm/mm_gran* and include/nuttx/gran.h: Add a simple granule- based allocator. The intent of this allocator is to support simple allocation of DMA I/O buffers. The initial check-in is code complete but untested (not event built into the mm/Makefile yet. * configs/fire-stm32v2: The board port is basically functional. Not all features have been verified. The ENC28J60 network is not yet functional. * configs/stm3240g-eval/discover: A configuration for testing the UDP discovery utility. Contributed by Max Holtzberg. * mm/README.txt: Add a new README file. * include/nuttx/usb/usb.h, arch/*/src/*usb.c, and arch/*/src/*otg*.c: Add hooks to to use common, external DMA buffer allocation implementation. * net/recvfrom.c: Don't block in recvfrom if (1) read-ahead buffering is enabled and (2) some data was obtained from read-ahead buffers. Blocking is a bad idea in that case because there is no timeout! (submitted by Max Holtzberg). * configs/stm3240g-eval/xmlrpc: An example configuration for the Embeddable Lightweight XML-RPC Server at apps/examples/xmlrpc. See http://www.drdobbs.com/web-development/ an-embeddable-lightweight-xml-rpc-server/184405364 for more info. Contributed by Max Holtzberg. * configs/*/nxwm/defconfig and sched/task_exithook.c: Fixes for bugs that crept in during recent changes. (Submitted by Max Holtzberg). * arch/arm/include/armv7-m/irq.h: Fix a critical bug in irqsave(). It looks like sometimes the compile will re-order some instructions inapproapriately. This end result is that interrupts will get stuck off. * drivers/mtd/w25.c: Beginning of a driver for the Windbond SPI FLASH family (W25x16, W25x32, and W25x64). The initial check-in is basically just the SST25 driver with some name changes. * arch/arm/include/armv7-m/irq.h and arch/arm/src/stm32/stm32_spi.c: Back out the last change in irq.h. It is (most likely) fine the way it was. The really interrupt related problem was in stm32_spi.c: When SPI3 is not enabled, then the irqrestore() falls in the else clause. * include/nuttx/compiler.h and other files: Moved always_inline and noinline __attributes__ here. Also replaced all occurrences of explicit __atributes__ in other files with definitions from this header file. * drivers/mtd/w25.c: The Windbond SPI FLASH W25 FLASH driver is code complete (but still untested). * arch/arm/src/stm32/stm32_i2c.c: I2C improvements from Mike Smith. Unified configuration logic; dynamic timeout calculations; I2C reset logic to recover from locked devices on the bus. * configs/*/*/Make.defs, tools/Config.mk, Makefile: Refactor all common make definitions from the various Make.defs files into the common tools/Config.mk. Add support for a verbosity options: Specify V=1 on the make command line in order to see the exact commands used in the build (Contributed by Richard Cochran). * drivers/net/enc28j60.c: The ENC28J60 Ethernet driver is now functional. * configs/fire-stm32v2: Add support or the fire-stm32v3 board as well (untested because I do not have a v3 board). * lib/stdio/lib_sscanf.c: Add %n psuedo-format (from Kate). * lib/stdio/lib_sscanf.c: There is an issue of handling input when (1) no fieldwidth is provided and (2) there is no space seperating the input values. No solutions is in place for this case now (either space or a fieldwidth must be provided). But at least some of the bad logic that attempted to handle this case has been removed (noted by Kate). * arch/arm/src/stm32/stm32_eth.c: DMA buffer sizes must be an even multiple of 4, 8, or 16 bytes. * arch/arm/src/stm32/stm32_idle.c: Fixes STM32F107 DMA issues: We cannot go into sleep mode while Ethernet is actively DMAing. * configs/shenzhou/src/up_ssd1289.c: Add infrastructure to support SSD1289 LCD. Initial checkin is just a clone of the STM32F4Discovery's FSMC-based LCD interface. The Shenzhou will need a completely need bit-banging interface; this initial check-in is only for the framework. * configs/shenzhou/src/up_ssd1289.c: Bit-banging driver is code complete. * configs/shenzhou/src/up_lcd.c: Oops. Shenzhou LCD does not have an SSD1289 controller. Its an ILI93xx. Ported the STM3240G-EVAL ILI93xx driver to work on the Shenzhou board. * configs/shenzhou/nxwm: Added an NxWM configuration for the Shenzhou board. This is untested on initial check-in. It will be used to verify the Shenzhou LCD driver (and eventually the touchscreen driver). * configs/shenzhou/src/up_touchscreen.c: Add ADS7843E touchscreen support for the Shenzhou board. The initial check-in is untested and basically a clone of the touchscreen support for the SAM-3U. * tools/cfgparser.c: There are some NxWidget configuration settings that must be de-quoted. * arch/arm/src/stm32/Kconfig: There is no SPI4. Some platforms support SPI3 and some do not (still not clear). * nuttx/configs/shenzhou: Various fixes to build new NxWM configuration. * configs/shenzhou: Oops. The Shenzhou LCD is and SSD1289, not an ILI93xx. * configs/shenzhou/src/up_ssd1289.c: The LCD is basically functional on the Shenzhou board. * graphics/nxmu: Correct some bad parameter checking that caused failures when DEBUG was enabled. * arch/arm/src/armv7-m/nvic.h: Add bit definitions for the AIRCR register. * drivers/input/ads7843.c: Need semaphore protection in logic that samples the position. * drivers/lcd/ssd1289.c: On some platforms we are unable to read the device ID -- reason unknown; workaround in place. * drivers/input/ads7843.c: Add thresholding options and an option to swap X and Y positions. Fix some logic errors in the SPI locking/selecting logic. * arch/arm/src/armv7-m/up_systemreset.c: Add logic to reset the Cortex-Mx using the AIRCR register. Contributed by Darcy Gong. * arch/arm/src/stm32/up_eth.c: Add logic specifically for the DM9161 PHY. If the DM9161 failed to initialize, then use the up_sysemreset() logic to reset the MCU. Contributed by Darcy Gong. * arch/arm/src/stm32/stm32_gpio.c: Add missing logic to set bit for SPI3 remap. This fixes the XPT2046 touchscreen driver using drivers/input/ads7843.c * configs/shenzhou/src/up_ssd1289.c: Fix naming error in conditional compilation. * configs/shenzhou/nxwm/defconfig: Disable reading from the LCD. This does not work. The hardware and the driver support the capability, but there is some bug that causes memory corruption. The work around for now: Just disable reading from the LCD. * drivers/lcd/ssd1289.c: Add some logic to reduce the amount of output when CONFIG_DEBUG_LCD is enabled. * configs/shenzhou/nxwm/defconfig: Bug found and fixed... The original configuration had too much stuff turned on. Reducing stack sizes, some features, and buffer sizes made the configuration reliable (Reading from the LCD is still disabled). * net/uip/uip_icmpping.c: Fix problem that prevented ping from going outside of local network. Submitted by Darcy Gong 6.23 2012-11-05 Gregory Nutt * arch/arm/src/stm32/stm32_rng.c, chip/stm32_rng.h, and other files: Implementation of /dev/random using the STM32 Random Number Generator (RNG). * board.h file for shenzhou, fire-stm32v2, and olimex-stm32-p107: Add frequencies for HSE, HSI, LSE, and LSI. These are needed by the STM32 watchdog driver. * CONFIG_EXAMPLES_*: To make things consistent, changed all occurrences of CONFIG_EXAMPLE_* to CONFIG_EXAMPLES_*. * drivers/mtd/w25.c and configs/*/src/up_w25.c: Several fixes for the W25 SPI FLASH. * configs/*/Make.defs: All buildroot tools now use the extension xxx-nuttx-elf- vs. xxx-elf- * configs/shenzhou/*/Make.defs: Now uses the new buildroot 4.6.3 EABI toolchain. * lib/stdio/lib_libdtoa.c: Another dtoa() fix from Mike Smith. * configs/shenzhou/src/up_adc.c: Add ADC support for the Shenzhou board (Darcy Gong). * configs/shenzhou/thttpd: Add a THTTPD configuration for the Shenzhou board (Darcy Gong). * include/termios.h and lib/termios/libcf*speed.c: The non-standard, "hidden" c_speed cannot be type const or else static instantiations of termios will be required to initialize it (Mike Smith). * drivers/input/max11802.c/h, and include/nuttx/input max11802.h: Adds support for the Maxim MAX11802 touchscreen controller (contributed by Petteri Aimonen). * graphics/nxtk/nxtk_events.c: Missing implementation of the blocked method. This is a critical bugfix for graphics support (contributed by Petteri Aimonen). * drivers/usbdev/pl2303.c, drivers/usbdev/usbmsc.h, and include/nuttx/usb/cdcacm.h: USB_CONFIG_ATTR_SELFPOWER vs. USB_CONFIG_ATT_SELFPOWER (contributed by Petteri Aimonen). * arch/arm/src/armv7-m/up_memcpy.S: An optimized memcpy() function for the ARMv7-M family contributed by Mike Smith. * lib/strings/lib_vikmemcpy.c: As an option, the larger but faster implemementation of memcpy from Daniel Vik is now available (this is from http://www.danielvik.com/2010/02/fast-memcpy-in-c.html). * lib/strings/lib_memset.c: CONFIG_MEMSET_OPTSPEED will select a version of memset() optimized for speed. By default, memset() is optimized for size. * lib/strings/lib_memset.c: CONFIG_MEMSET_64BIT will perform 64-bit aligned memset() operations. * arch/arm/src/stm32/stm32_adc.c: Need to put the ADC back into the initial reset in the open/setup logic. Opening the ADC driver works the first time, but not the second because the device is left in a powered down state on the last close. * configs/olimex-lpc1766stck/scripts: Replace all of the identical ld.script files with the common one in this directory. * configs/stm3220g-eval/scripts: Replace all of the identical ld.script files with the common one in this directory. * configs/hymini-stm32v/scripts: Replace all of the identical ld.script files with the common one in this directory. * configs/lpcxpresso-lpc1768/scripts: Replace all of the identical ld.script files with the common one in this directory. * binfmt/elf.c, binfmt/libelf, include/elf.h, include/nuttx/elf.h: Add basic framework for loadable ELF module support. The initial check- in is non-functional and is simply the framework for ELF support. * include/nuttx/binfmt.h, nxflat.h, elf.h, and symtab.h: Moved to include/nuttx/binfmt/. * arch/sim/src/up_elf.c and arch/x86/src/common/up_elf.c: Add for ELF modules. * arch/arm/include/elf.h: Added ARM ELF header file. * include/elf32.h: Renamed elf.h to elf32.h. * configs/stm32f4discovery/ostest: Converted to use the new Kconfig-based configuration system. * configs/stm32f4discovery/elf and configs/stm32f4discovery/scripts/gnu-elf.ld Add a configuration for testing the ARM ELF loader. * binfmt/libelf: Can't use fstat(). NuttX does not yet support it. Damn! * binfmt/libelf: The basic ELF module execution appears fully functional. * configs/shenzhou/src/up_relays.c: Add support for relays from the Shenzhou board. Contributed by Darcy Gong. * lib/fixedmath: Moved the old lib/math to lib/fixedmath to make room for the math library from the Rhombus OS * lib/math: Now contains the math library from the Rhombus OS by Nick Johnson (submitted by Darcy Gong). * include/float.h: Add a first cut at the float.h header file. This really should be an architecture/toolchain-specific header file. It is only used if CONFIG_ARCH_FLOAT_H is defined. * lib/math: Files now conform to coding standards. Separated float, double, and long double versions of code into separate files so that they don't draw in so much un-necessary code when doing a dumb link. * binfmt/libelf: The ELF loader is working correctly with C++ static constructors and destructors and all. * Documentation/NuttXBinfmt.html: Add documentation of the binary loader. * configs/sim/ostest: Converted to use the mconf configuration tool. * configs/sim/cxxtest: New test that will be used to verify the uClibc++ port (eventually). * include/nuttx/fs/fs.h, lib/stdio/lib_libfread.c, lib_ferror.c, lib_feof.c, and lib_clearerr.c: Add support for ferror(), feof(), and clearerror(). ferror() support is bogus at the moment (it is equivalent to !feof()); the others should be good. * configs/stm32f4discovery/include/board.h: Correct timer 2-7 base frequency (provided by Freddie Chopin). * include/nuttx/sched.h, sched/atexit.c, and sched/task_deletehook.c: If both atexit() and on_exit() are enabled, then implement atexit() as just a special caseof on_exit(). This assumes that the ABI can handle receipt of more call parameters than the receiving function expects. That is usually the case if parameters are passed in registers. * libxx/libxx_cxa_atexit(): Implements __cxa_atexit() * configs/stm32f4discovery/cxxtest: New test that will be used to verify the uClibc++ port (eventually). The sim platform turned not to be a good platform for testing uClibc++. The sim example will not run because the simulator will attempt to execute the static constructors before main() starts. BUT... NuttX is not initialized and this results in a crash. On the STM324Discovery, I will have better control over when the static constructors run. * RGMP 4.0 updated from Qiany Yu. * configs/*/Make.defs and configs/*/ld.script: Massive clean-up and standardization of linker scripts from Freddie Chopin. * net/netdev_ioctl.c: Add interface state flags and ioctl calls to bring network interfaces up and down (from Darcy Gong). * config/stm32f4discovery: Enable C++ exceptions. Now the entire apps/examples/cxxtest works -- meaning that the uClibc++ is complete and verified for the STM32 platform. 6.24 2012-12-20 Gregory Nutt * arch/arm/src/stm32: Support for STM32F100 high density chips added by Freddie Chopin. * configs/stm32f100_generic: Support for generic STM32F100RC board contributed by Freddie Chopin. * arch/arm/src/stm32_otgfsdev.c: Partial fix from Petteri Aimonen. * drivers/lcd/ug-2864ambag01.c and include/nuttx/lcd/ug_2864ambag01.h: LCD driver for the Univision OLED of the same name (untested on initial check-in). * configs/stm32f4discovery/nxlines: Configure to use mconf/Kconfig tool. * configs/stm32f4discovery/src/up_ug2864ambag01.c: Board-specific initialization for UG-2864AMBAG01 OLED connecte to STM32F4Disovery. * libxx/libxx_stdthrow.cxx: Exception stubs from Petteri Aimonen. * configs/stm32f4discovery/src/up_ug2864ambag01.c: Driver has been verified on the STM32F4Discovery platform. Some tuning of the configuration could improve the presentation. Lower resolution displays are also more subject to the "fat, flat line bug" that I need to fix someday. See http://www.nuttx.org/doku.php?id=wiki:graphics:nxgraphics for a description of the fat, flat line bug. * libc: Renamed nuttx/lib to nuttx/libc to make space for a true lib/ directory that will be forthcoming. Also rename libraries: liblib.a -> libc.a, libulib.a -> libuc.a, libklib.a -> libkc.a, liblibxx.a ->libcxx.a. (I will probably, eventually rename libxx to libcxx for consistency) * Makefile, lib/: A new, empty directory that will hold generated libraries. This simplifies the library patch calculations and lets me get rid of some bash logic. The change is functional, but only partially complete; additional logic is needed in the arch/*/src/Makefile's as well. Right now that logic generate multiple library paths, all pointing to the lib/ directory. * arch/*/src/Makefile: Now uses only the libraries in lib/ Replace bash fragments that test for board/Makefile. * Makefile.win: The beginnings of a Windows-native build. This is just the beginning and not yet ready for prime time use. * configs/stm32f4discovery/winbuild: This is a version of the standard NuttX OS test, but configured to build natively on Windows. Its only real purpose is to very the native Windows build logic. * tools/mkdeps.bat and tools/mkdeps.c: mkdeps.bat is a failed attempt to leverage mkdeps.sh to CMD.exe. It fails because the are certain critical CFLAG values that cannot be passed on the CMD.exe command line (like '='). mkdeps.c is a work in progress that will, hopefully, replace both mkdeps.sh and mkdeps.bat. * tools/Config.mk: Centralize the definition of the script that will be used to generated header file include paths for the compiler. This needs to be centralized in order to support the Windows native build. * tools/incdir.bat: A replacement for tools/incdir.sh for use with the the Windows native build. * Makefile.unix: The existing top-level Makefile has been renamed Makefile.unix. * Makefile: This is a new top-level Makefile that just includes either Makefile.unix or Makefile.win * configs/stm3240g-eval/src: Qencoder fixes from Ryan Sundberg. * arch/arm/src/stm32/stm32_qencoder.c: TIM3 bug fix from Ryan Sundberg. * tools/mkromfsimg.sh: Correct typo in an error message (Ryan Sundberg) * arch/*/src/Makefile: Remove tftboot install and creation of System.map for Windows native build. The first is a necessary change, the second just needs re-implemented. * configs/mirtoo: Update Mirtoo pin definitions for Release 2. Provided by Konstantin Dimitrov. * Fixed an uninitialized variable in the file system that can cause assertions if DEBUG on (contributed by Lorenz Meier). * Config.mk: Defined DELIM to be either / or \, depending upon CONFIG_WINDOWS_NATIVE. This will allow me to eliminate a lot of conditional logic elsewhere. * nuttx/graphics: One a mouse button is pressed, continue to report all mouse button events to the first window that received the initial button down event, even if the mouse attempts to drag outside the window. From Petteri Aimonen. * nuttx/graphics/nxmu/nx_block.c: One more fix to the NX block message logic from Petteri Aimonen. * include/nuttx/wqueue.h: Some basic definitions to support a user- space work queue (someday in the future). * graphics/nxmu: Add semaphores so buffers messages that send buffers will block until the buffer data has been acted upon. * graphics/nxmw: Extended the blocked messages to cover mouse movement and redraw events. These will also cause problems if sent to a window while it is closing. * arch/several: Change UARTs are enabled for i.MX, LM3S, ez80, and M16C to match how they are enabled for other architectures. * configs/ez80f910200kitg: Convert to use mconf configuration. * sched/pause.c: Implements the POSIX pause() function. * ez80: Lots of changes to ez80 configurations and build logic as I struggle to get a clean Windows build (still not working). * configs/cloudctrl: Darcy Gong's CloudController board. This is a small network relay development board. Based on the Shenzhou IV development board design. It is based on the STM32F107VC MCU. * arch/arm/src/stm32_serial.c and stm32_lowputc.c: Added optional RS-485 direction bit control. From Freddie Chopin. * Lots of build files: ARMv7-M and MIPS32 Make.defs now include a common Toolchain.defs file that can be used to manage toolchains in a more configurable way. Contributed by Mike Smith * configs/stm32f4discovery/winbuild and configs/cloudctrl: Adapted to use Mike's Toolchain.defs. * tools/configure.sh: Adapted to handle paths and setenv.bat files correctly for native Windows builds. * More of build files: AVR and AVR32 Make.defs now include a common Toolchain.defs file that can be used to manage toolchains in a more configurable way. Contributed by Mike Smith * tools/incdir.sh and incdir.bat: Add -s option to generate system header file paths. * nuttx/arch/arm/src/arm/Toolchain.defs: Add support for more ARM toolchains (from Mike Smith). * arch/arm/src/stm32/stm32f40xxx_rcc.c: Enabled FLASH prefetch (from Petteri Aimonen). * graphics/nxtk/nxtk_filltrapwindow.c: Correct an offset problem (from Peterri Aimonen). * graphics/nxglib/nxglib_splitline.c: Fix error in drawing of near horizontal lines (from Peterri Aimonen). * sched/task_exithook.c: Missing right bracket with certain conditional compilation (thanks James Goppert). * arch/arm/srch/stm32/stm32_otgfshost.c: Replace timeout handling; use system tick instead of frame counter. The frame counter gets reset to zero at 0x3fff making it error prone. * arch/arm/src/stm32/stm32f20xx_rcc.c and stm32f40xx_rcc.c: Added option CONFIG_STM32_FLASH_PREFETCH. FLASH prefetch will now only be enabled if this option is selected. * configs/ez80f910200zco/ostest: Now uses Kconfig/mconf configuration tool. Updated to build in native Windows environment. Other ez80f910200zco build scripts also updated. * configs/z8f64200100kit/ostest: Update to same level as ez80 configurations. * nuttx/configs/z8f64200100kit/scripts/setenv.bat: Add support for native Windows build. * nuttx/arch/arm/src/lpc17xx/lpc17_i2c.c: Resources not being released when I2C is uninitialized. * cloudctrl/src/up_chipid.c and shenzhou/src/up_chipid.c: Add functions to get chip ID. Contributed by Darcy Gong. These should not be board-dependent, but should be in arch/arm/src/stm32 where they can be used from any board. * sched/work_thread.c: Fix backward conditional compilation. This might has caused a memory leak. From Freddie Chopin. * configs//Make.defs: Fix typo -wstrict-prototypes should be -Wstrict-prototypes (From Denis Carilki). * arch/arm/src/calapyso/calypso_keypad.c: Add Calypso keypad driver. From Denis Carilki. * z8encore000zco/ostest and z8f64200100kit/ostest: Converted to use Kconfig/ mconf configuration tool. * arch/arm/src/armv7-m/up_exception.S: missing curly braces for push/pop From Freddie Chopin. * z8encore000zco/ostest and z8f64200100kit/ostest: Can now be modified to support the Windows native builds (see corresponding README.txt files). * configs/z16f2800100zcog - All configurations updated to use the ZDS-II 5.0.1 toolchain. * configs/z16f2800100zcog - All configurations updated to use Kconfig/mconf configuration tools. * configs/z16f2800100zcog/ostest - Now supports a native Windows build (other ZNEO configs may also support the native build, but this has not been verfiied). * include/nuttx/input/keypad.h, arch/arm/src/calypso/calypso_keypad.c, and configs/compal_e99/nsh_highram: First cut at a standard keypad interface definition. Contributed by Denis Carikli. * libc/stdlib/lib_rand.c: Always add one to result congruential generators to avoid the value zero. Suggested by Freddie Chopin. * tools/b16.c: Fixed precision math conversion utility. * graphics/nxglib/nxglib_splitline.c: Fix the "fat, flat line bug" * arch/z80/src/*/Toolchain.defs: Add dummy Toolchain.defs files for the z80 family. * configs/z80sim/ostest: Converted to build with the Kconfig/mconf tool. Current configuration failed to build for me (Ubuntu 12.10, SDCC 3.2.0 pre-built for Linux) due to a glibc memory corruptionerror in SDCC. * configs/z80sim/ostest: Default is now the Windows native build. See configs/z80sim/README.txt for instructions to convert back to a Linux or or Cygwin build. * arch/z80/src/Makefile.sdccw: Renamed makefiles with extensions zdiil, zdiiw, sdccl, and sdccw for the ZDS-II vs SDCC compilers and for the POSIX vs Windows native builds. * nuttx/drivers/mtd/ftl.c: Fix for the flash translation layer. Short unaligned writes were buggy. From Petteri Aimonen. * nuttx/libc/math/lib_round*.c: Add rounding functions to the math library. Contributed by Petteri Aimonen. * include/cxx/cstdlib: Add stroul(). From Petteri Aimonen. * arch/*/include/limits.h: Change signed minimum values from, for example, (-128) to (-127 - 1) to avoid overflows under certain conditions. From Peterri Aimonen. * graphics/nxtk/nxtk_subwindowmove.c: Previously it was very difficult to do e.g. "scroll by dx, dy". When given the full window area, nxtk_subwindowmove would clip the offset always to 0,0. It makes more sense for it to clip the source area and not modify the offset. From Petteri Aimonen. * graphics/nxtk/nxtk_getwindow.c: Clipping would change the offset of returned data, and caller has no way to know what the new offset would be. This messes up font drawing when the text is partially out of window, e.g. when scrolling. Also from Petteri Aimonen. * include/stdbool.h: Can now be disabled for C++ files if CONFIG_C99_BOOL8 is defined. CONFIG_C99_BOOL8 indicates (1) that the sizeof(_Bool) is one in both C and C++, and (2) the C compiler is C99 and supports the _Bool intrinsic type. Requested by Freddie Chopin. * include/stdlib/lib_rand.c: Various additional changes so that the integer value zero can be returned. Requested by Freddie Chopin. * arch/z80/src/Makefile.sdcc*, z80/up_mem.h: Redesign Z80 build so that it no longer depends on Bash scripts. * configs/z80sim/nsh and pashello: Converted to (1) use the kconfig-frontends configuration tool, and (2) to build natively under Windows. The NSH configuration is verified; the pashello configuration needs a more TLC. * tools/copydir.sh: Rename tools/winlink.sh to tools/copydir.sh * tools/link.bat, unlink.bat, and copydir.bat: Add Windows counterparts to the link.sh, unlink.sh, and copydir.sh Bash scripts. * configs/z80sim/pashello: Now builds correctly. * configs/xtrs/ostest, nsh, and pashello: Converted to (1) use the kconfig- frontends configuration tool, and (2) to build natively under Windows. * drivers/serial/Kconfig and sched/Kconfig: Two names for same configuration: CONFIG_LOWLEVEL_CONSOLE is bogus and CONFIG_DEV_LOWCONSOLE is in the wrong Kconfig file. Moved to drivers/serial/Kconfig replacing CONFIG_LOWLEVEL_CONSOLE. * arch/z80/include/z180: Add header files for z180 chips. Initial versions are just clones of z80 header files. * arch/z80/src/z180: Add source files for z180 chips. Initial versions are just clones of z80 source files. * include/nuttx/arch.h: Add address environment control interfaces (for use with CPUs the provide MCUs and support process-like address environments). * arch/z80/src/z180/z180_mmu.*: Add MMU support for z180 tasks. * configs/p112: Add very basic board support and an examples/ostest configuration for the venerable P112 board. * sched/os_bringup.c: If CONFIG_PATH_INITIAL is defined, then the initial environment of the task started by os_bringup() will have the PATH environment variable defined to be that string. * binfmt/binfmt_exepath.c: If CONFIG_BINFMT_EXEPATH is defined, then this file will be built. It contains logic to search for regular files at the absolutes paths found in the current PATH environment variable setting. This is untested and not yet hooked into the binfmt exec() logic on initial check-in * binfmt/binfmt_loadmodule.c: load_module() will now traverse the PATH variable to locate files from their relative path. * include/nuttx/arch.h and arch/z80/src/z180/z180_mmu.c: Restructure the address environment interfaces so that they will better integrate with binfmt/. * binfmt/libelf/*, binfmt/libnxflat/* and other files: Integrate the address environment interfaces. If CONFIG_ADDRENV=y, then binfmt/ will now create an address environment for new tasks (instead of just malloc'ing the task memory). * configs/stm32f4discovery/elf: Enable support/test of the PATH to find executables using a relative path. 6.25 2013-02-01 Gregory Nutt * graphics/: Adds 5x8 monospace font. This tiny font is useful for graph labels and for small bitmapped display. Contributed by Petteri Aimonen. * configs/stm3220g-eval/nxwm: Converted to use the kconfig-frontends configuration tool. * configs/sim/nxwm: Converted to use the kconfig-frontends configuration tool. * include/pthread.h: In sys/prctl.h because it is needed by pthread_[set|get]name_np() * tools/kconfig.bat: Kludge to run kconfig-frontends from a DOS shell. * sched/sig_timedwait.c: Should always move the time up to the next largest number of system ticks. The logic was rounding. Noted by Petteri Aimonen. * arch/arm/src/up_head.S: Fix backward conditional compilation. NOTE there is a issue of ARM9 systems with low vectors and large memories that will have to be addressed in the future. * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Add logic to marshal and serialize speical keyboard commands intermixed with normal ASCII data (not yet hooked into anything). * drivers/usbhost/usbhost_hidkbd.c: If CONFIG_HIDKBD_ENCODED is defined, this driver will now use libc/misc/lib_kbdencode.c to encode special function keys. * configs/olimex-lpc1766stk/hidkbd: This configuration has been converted to use the kconfig-frontends configuration tool. * drivers/lcd/ug-2864hsweg01.c and include/nuttx/lcd/ug-2864hsweg01.h: Driver for UG-2864HSWEG01 OLED contributed by Darcy Gong. * configs/stm32f4discovery/src/up_ug2864hsweg01.c: Support for the UG-2864HSWEG01 OLED for the STM32F4Discovery board. * drivers/usbhost/usbhost_hidkbd.c: Correct a logic error in how tasks waiting for read data are awakened. * libc/misc/lib_kbdencode.c and lib_kbddecode.c: Now handles keypress events too. However, the USB HID keyboard driver has not yet been updated to detect key release events. That is kind of tricky in the USB HID keyboard report data. * configs/mcu123-214x/nsh: Converted to use the kconfig-frontends configuration tool. * configs/zp214xpa: Add basic support for the The0.net ZP213x/4xPA board (with the LPC2148 and the UG_2864AMBAG01). * configs/sim/nxlines: Add an nxlines configuration for the simulator. * configs/zp214xpa/nxlines: Add an nxlines configuration for the ZP213x/4xPA (with the LPC2148 and the UG_2864AMBAG01). Working as of 2012-12-30. * configs/olimex-lpc1766stk/wlan: Remove non-functional configuration. * configs/stm32f4discovery/src and nuttx/drivers/lcd/ug-2864hsweg01.c: Updates and corrections for the UG-2864HSWEG01 from Darcy Gong. * configs/lm326965-ek: All configurations converted to use the kconfig-frontends configuration tool. * configs/Kconfig: NSH_MMCSDSPIPORTNO should depend on MMCSD_SPI, not just SPI (from Jose Pablo Carballo). * arch/arm/src/arm/Kconfig and armv7m/Kconfig: Add an option for buildroot toolchains: They may be EABI or OABI. * include/nuttx/progmem and arch/arm/src/stm32/stm32_flash.c: Fix a counting bug plus change interface to use either relative or absolute FLASH addressing (from Freddie Chopin). * libc/misc/Make.defs: Fix error in conditional for KBD CODEC. * libc/Kconfig and configs/*/defconfig (several): The default setting should be CONFIG_LIB_KBDCODEC=n * tools/configure.c: configure.c can be used to build a work-alike program as a replacement for configure.sh. This work-alike program would be used in environments that do not support Bash scripting (such as the Windows native environment). * tools/configure.bat: configure.bat is a small Windows batch file that can be used as a replacement for configure.sh in a Windows native environment. configure.bat is actually just a thin layer that executes configure.exe if it is available. If configure.exe is not available, then configure.bat will attempt to build it first. * arch/arm/src/lpc17xx/lpc17_syscon.h: Correct some typos in bit definitions (from Rommel Marcelo). * libc/string/lib_strndup.c: strndup() should use strnlen(), not strlen(), to determine the size of the string. * sched/os_bringup.c: Remove support for CONFIG_BUILTIN_APP_START. This is not really a useful feature and creates a violation of the OS layered architecture. * include/unistd.h, arch/arch/src/*: Implement a simple vfork(). On initial checkin, this API is available only for ARM platforms. * binfmt/binfmt_exec.c: exec() now sets the priority of the new task to the same priority as the current task (instead of the arbirtrary value of 50). * libc/unisted/lib_execv.c and lib_execl.c: New, somewhat flawed, implementations of execv() and execl(). * tools/cfgdefine.c: Strips quotes from CONFIG_EXECFUNCS_SYMTAB value. * arch/arm/include/lm3s/chip.h: Move chip definitions into public include area for compatibility with other architectures. * arch/arm/src/lm3s/chip: Move register definition header files into a new chip/ sub-directory. * arch/arm/src/lm3s/lm3s_internal.h: Broke up into several smaller header files. * arch/arm/src/lm: Rename the arch/arm/src/lm3s directory to arch/arm/src/lm so that is can support other members of the Stellaris family. * libc/spawn: Add file action interfaces needed by posix_spawn(). * sched/clock_time2ticks.c: Another case where time was being rounded down instead of up (from Mike Smith). * libc/spawn: Implementation of posix_spawn() is complete but untested and undocumented. * drivers/usbdev/pl2303.c: Fix typols in the PL2303 driver (from Max Holtzberg). * configs/stm32f4discovery/posix_spawn: Added a configuration that can be used for testing posix_spawn(). * arch/arm/src/stm32: Bring F1 support for general DMA and serial DMA in paricular up to parity with F2/F4 (from Mike Smith). * libc/stdio/lib_libfread.c: Correct some error handling when lib_fread() was passed a bad stream. Needed to move the releasing of a semaphore inside of some conditional logic (cosmetic). * include/nuttx/sched.h, sched/task_setup.c, and sched/task_exithook.c: Add support for remembering the parent task and sending SIGCHLD to the parent when the task exists. * sched/task_exithook.c: Fixed a *critical* bug. Here is the scenario: (1) sched_lock() is called increments the lockcount on the current TCB (i.e., the one at the head of the ready to run list), (2) sched_mergepending is called which may change the task at the head of the ready-to-run list, then (3) sched_unlock() is called which decrements the lockcount on the wrong TCB. The failure case that I saw was that pre-emption got disabled in the IDLE thread, locking up the whole system. * sched/sched_waitpid.c: Use SIGCHLD instead of a semaphore. This is a much more spec-compliant implementation. However, there are some issues with overruning signals because NuttX does not support queueing of signals (POSIX does not require it). I think it may need to. * sched/sched_waitid.c and sched_wait.c: Add support for waitid() and wait(). See issues with waitpid() above. * include/nuttx/fs/fs.h and fs/fs_files.c: Add a dup() method to the struct mountpt_operations. When dup'ing a file that resides on a mounted volume, let the file system's dup() method do the work. * fs/romfs/fs_romfs.c: Implemented the dup() method for the ROMFS file system. * fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and fs/nfs/nfs_vfsops.c: Add hooks for dup() method (not yet implemented). * fs/romfs: Remove the rf_open flag. It looks good, but actually does nothing. * fs/fat: Remove the ff_open flag. Same story as for the ROMFS rf_open flag. * fs/fat/fs_fat32.c, fs/nxffs/nxffs_initialize, and fs/nfs/nfs_vfsops.c: Completed implementation of the dup() methods. There is still no good test available. * sched/sig_timedwait.c: sigtimedwait() would return a bad signal number if the signal was already pending when the function was called. * configs/ubw32/scripts: All common linker scripts moved to this scripts sub-directory * configs/ubw32/ostest: Configuration configured to use the kconfig-frontends tools. * arch/mips/src/mips32/up_vfork.c, up_vfork.h, and vfork.S: Implement vfork() for MIPS32 (no floating point support) * configs/ubw32/ostest: Enable the vfork() test. * fs/binfs: Move apps/builtin/binfs.c to fs/binfs/fs_binfs.c CONFIG_APPS_BINDIR rename CONFIG_FS_BINFS * include/nuttx/binfmt/builtin.h: Some of the content of apps/include/apps.h moved to include/nuttx/binfmt/builtin.h * binfmt/libbuiltin/libbuiltin_utils.c: Move builtin utility functions from apps/builtin/exec_builtins.c to binfmt/libbuiltin/libbuiltin_utils.c * binfmt/builtin.c and binfmt/libbuiltin: Add a binary "loader" that can be used to execute builtin programs from the BINFS file system. * configs/sim/nsh: Convert to use kconfig-frontends configuration tool. * binfmt/binfmt_schedunload.c: Add logic based on SIGCHLD to automatically unload and clean-up after running a task that was loaded into memory. * binfmt/libbuiltin: Extensions from Mike Smith * sched/task_reparent.c: Add internal interface to change the parent task. * sched/task_posixspawn(): Move libc/spawn/lib_ps.c to sched/task_posixspawn() now it requires internal, reparenting interfaces * include/nuttx/spawn(): Move libc/spawn.h to include/nuttx/spawn.h * arch/arm/include/lpc17xx/chip.h, irq178x.h: Integrate Marcelo Rommel's LPC1788 definitions into the base LPC17xx. * configs/olimex-lpc1766stk/nsh: Convert configuration to use the kconfig-frontends tools. * sched/task_reparent.c: Simplify reparenting interface. * arch/arm/src/[many]: More LPC1788 definitions from Rommel Marcelo incorporated. * configs/open1788: Board configuration for the Wave Share Open1788 board. Still fragmentary (contributed by Rommel Marcelo, adapted to use kconfig-frontends. * net/send(): Add logic to work around delayed ACKs by splitting packets (contributed by Yan T.). * net/recvfrom(): Fix a bug. When the host closes a connection (gracefully). recv[from]() returned success and the closure was never detected. Hmmm.. I don't know why the network monitor did not catch this event. This is an important bug fix. * net/recvfrom(): Fix a introduced with the last bugfix. If the peer does an orderly closure of the socket, report 0 not -ENOTCONN * configs/lm3s6965-ek/README.txt and tools/: Add an OpenOCD configuration for the LM3S (from Jose Pablo Carballo). * nuttx/lcd/hd4478ou.h and configs/pcblogic-pic32mx/src/up_lcd1602: Start of support of LCD1602 alphanumeric LCD. I need a few more parts before I can finish integrating this one. * arch/arm/src/*/chip.h and arch/arm/include/*/chip.h: Move all priority ranges from the src to the include chip.h header file. * arch/arm/include/armv7-m/irq.h: Add inline functions to enable and disable interrupts via the BASEPRI register. * arch/arm/Kconfig: Add new option CONFIG_ARM7VM_USEBASEI * arch/arm/src/*/*_irq.c: Set the priority of the SVCALL exception to the highest possible value. * arch/armv7-m/up_hardfault.c: Fail if a hardfault occurs while CONFIG_ARM7VM_USEBASEPRI=y. * arch/arm/src/stm32/stm32_serial.c: Add support for USART single wire mode (Contributed by the PX4 team). * sched/: Implement support for retaining child task status after the child task exists. This is behavior required by POSIX. But in NuttX is only enabled with CONFIG_SCHED_HAVE_PARENT and CONFIG_SCHED_CHILD_STATUS * Add support for keyboard encode to the keypad test (from Denis Carikli). * configs/olimex-lpc1766stk/nettest: Configuration converted to use the kconfig-frontends tools. * net/net_poll.c: Split net_poll() to create psock_poll() too. * net/net_poll.c: Fix poll/select issure reported by Qiang: poll_interrupt() must call net_lostconnection() when a loss of connection is reported. Otherwise, the system will not know that the connection has been lost. * sched/group_create.c, group_join.c, and group_leave.c: Add support for task groups. * sched/group_signal.c and task_exithook.c: Send signal to all members for the parent task group. * include/nuttx/sched.h and sched/env_*.c: Move environment variables into task group structure. * sched/: Lots of file changed. Don't keep the parent task's task ID in the child task's TCB. Instead, keep the parent task group IN the child task's task group. * fs/, sched/, include/nuttx/sched.h, and include/nutts/fs/fs.h: Move file data from the TCB to the task group structure. * libc/stdio/, sched/, include/nuttx/lib.h, and include/nutts/fs/fs.h: Move stream data from the TCB to the task group structure. * net/, sched/, and include/nuttx/net/net.h: Move socket data from the TCB to the task group structure. * sched/task_starthook.c, sched/task_start.c, and include/nuttx/sched.h: Add a task start hook that will be called before the task main is started. This can be used to schedule C++ constructors to run automatically in the context of the new task. * binfmt/binfmt_execmodule: Execute constructors as a start hook. * sched/os_start.c: Fix ordering of group initialization. * configs/stm32f4discovery/usbnsh: Add an NSH STM32F4Discovery configuration that uses USB CDC/ACM for the NSH console. * configs/stm32f4discovery/nsh: Converted to use the kconfig-frontends tools. * configs/*/src/up_userleds.c: Fix a error that was cloned into all STM32 user LED code. The wrong definitions were being used to set LEDs on or off. * arch/*/common/up_internal.h and arch/*/common/up_initialize.c: Serial was driver was not being built if there is no console device. Obviously, the serial driver may be needed even in this case. * arch/arm/src/stm32/stm32_serial.c: If there is a serial console, it would be ttyS0 and the others would be ttyS1-5. If there is not serial console, was labeling them ttyS1-6; now labels them ttyS0-5. * fs/fs_syslog.c: Can't handle SYSLOG output to character device from the IDLE task (because it can't block). syslog_putc now returns EOF on failure and sets errno. Fixed some errors in error handling. * libc/stdio/lib_syslogstream.c: Checking of return value from syslog_putc was bogus. Switching to EOF for all errors solves this. * arch/arm/src/lm/chip/lm4f_memorymap.h: More LM4F changes from Jose Pablo Carballo. * drivers/serial/serial.c, include/nuttx/serial/serial.h, drivers/usbdev/cdcacm.c, and drivers/pl2303.c: Add support for removable serial devices (like USB serial). This support is enabled by CONFIG_SERIAL_REMOVABLE. * arch/*/src/*/Toolchain.defs: Change assignment so that we can override CROSSDEV with a make command line argument. * include/assert.h: Mark assertion functions as non-returning. * arch/*/src/*/up_assert.h: Mark _up_assert() as non-returning. * drivers/mtd/at25.c: When the AT25 device was not available the initialization did not fail like it should. From Petteri Aimonen. * fs/fat/fs_configfat.c: Fix some errors in FAT formatting logic for large devices and for FAT32. From Petteri Aimonen. * fs/fat/fs_fat32util.c: Fix an initialization error found by Petteri Aimonen. freecount and next freecount initialization were reversed. * drivers/mmcsd/mmcsd_spi.c: Some SD cards will appear busy until switched to SPI mode for first time. Having a pull-up resistor on MISO may avoid this problem, but this patch makes it work also without pull-up. From Petteri Aimonen. * fs/fat/fs_fat32.c: Fix a compilation error when FAT_DMAMEMORY=y. From Petteri Aimonen. * arch/arm/src/stm32/chip/stm32_spi.h: STM32F4 max SPI clock freq is 37.5 MHz. Patch from Petteri Aimonen. * arch/arm/src/stm32/stm32_spi.c: Fixes for SPI DMA work on the STM32F4. Includes untested additions for the F1 implementation as well. From Petteri Aimonen. 6.26 2013-03-15 Gregory Nutt * drivers/serial/serial.c: Correct some race conditions when checking for disconnection of a removable serial device. * sched/task_posixspawn.c, task_spawn.c, task_spawnparms.c and spawn_internal.h: Create new interface task_spawn() that is like posix_spawn(), but uses entry point addresses like task_create(). * Corrected all argv[] arguments. Should be char * const *, not const char **. * sched/pthread* and include/nuttx/sched: Move pthread join data and pthread key calculation data into the "task group" structure. * sched/atexit.c, on_exit.c, task_exithook.c and include/nuttx/sched.h: Move atexit and on_exit data structures to task group. These callbacks are only issued now when the final member of the task group exits. * sched/waitpid.c, task_exithook.c and include/nuttx/sched.h: Move waitpid data data structures to task group. Callers of of waitpid() are now only awakened when the final thread of the task group exits. * sched/mq_descreate.c, mq_open.c, mq_remove.c, group_leave.c, and include/nuttx/sched.h: Move list of opened message queues to the task group structures. Now all message queues opened by members of the group are closed when the last member of the group exits. * includes/nuttx/sched.h and Lots of files: Change name of _TCB to struct tcb_s so that (1) it is consitent with other NuttX naming and so that (2) the naming can handle some upcoming changes. * includes/nuttx/sched.h and sched/: There are three TCB structures: struct tcb_s is a generic common version, struct task_tcb_s is a version for tasks and kernel threads and pthread_tcb_s is a version for pthreads. By dividing the TCB structure into these variants, pthreads do not have to be burdened by task-specific data structures (and vice versa). * sched/task_exithook.c adn group_create.c: Fix an error, the task within the task group may exit early leaving a pthread to exit the task group last. In this case, we need to remember the the PID of the main task in the task group and use that PID for signalling SIGCHILD to the parent task group. * included/nuttx/sched.h and sched/sig*.c: Numerous changes to the signal deliver logic so that the delivery of signals to threads within a task group will be compliant with delivery of signals to threads within a POSIX process. * sched/mq_recover.c and task_exithook.c: Add logic to handle the case where a task is deleted (or pthread canceled) while it is waiting on a message queue. task_delete() and pthread_cancel() are dangerous interfaces. This is only one feeble recover measure of *many* that would be needed to do this safely. * sched/group_killchildren.c, task_recover.c, group_foreachchild.c, sched/restart.c, sched/task_delete.c, and others: Beef up logic to better support task deletion and pthread cancellation. Needed to pass need OS test case for task_restart(). * sched/include/sched.h and all timed functions in sched/: Move timer from local variables to TCB. This is needed so that if a task is canceled or restarted while it is waiting for a timed event, we can gracefully recover. We can't let the timer expire after the task has been deleted. * arch/arm/include/stm32 and arch/arm/src/stm32: Add support for the STM32 F3 family (still missing some things). * configs/stm32f3discovery: This will (eventually) be support for the STM32F3Discovery board. * STM32 F3 and STM32F3Discovery port is complete a ready for test. * arch/arm/src/lpc17xx: Add support for the Cortex-M4 FPU and Mikes "common vector" logic. The LPC1788 is going to need these things. * arch/arm/src/stm32/stm32_spi.c: Fix SPI DMA logic that does not work if sem_wait() is interrupt by a signal. From Petteri Aimonen. * drivers/input/max11802.c: MAX11802: Fix a timing bug that corrupted coordinates. From Petteri Aimonen. * drivers/mmcsd/mmcsd_spi.c: Use SPI locking so that MMC/SD can exist on the same bus as other SPI devices. From Petteri Aimonen. * graphics/nxfonts/nxfonts_sans17x22.h: Small mod to hyphen in sans17x22 font. The hyphen did not have any space on its sides. This caused it to run together with other characters so that for example "+-" would look weird. From Petteri Aimonen. * mm/mm_mallinfo.c: Take MM semaphore in mm_mallinfo. From Petteri Aimonen. * configs/stm32f3discovery/nsh/defconfig: Disable SPI. It is not used. * drivers/mtd/sst39vf: Add a driver for the SST29VF NOR FLASH parts. * sched/os_start.c: Add an additional call-out to support board- specific driver initialization during the start phase: If CONFIG_BOARD_INITIALIZE is defined, then an additioinal initialization function called board_initialize() will be called just after up_initialize() is called and just before the initial application is started. * arch/arm/src/stm32/stm32_otgfsdev.c, drivers/usbdev/usbdev_trprintf.c, and include/nuttx/usb/usbdev_trace.h: Add logic to support decoding of device-specific trace events to make the trace ouput more readable. From Petteri Aimonen. * arch/arm/src/stm32/stm32_otgfsdev.c: Need to manually set CNAK in the case where we are waiting for a SETUP command with DATA. Otherwise, the core may NAK further transactions. From Petteri Aimonen. * arch/arm/src/stm32/stm32_otgfsdev.c: Add logic to prevent premature to IDLE state. This change (plus the previous) was necessary to get the CDC/ACM driver working the certain STM32 F4 hardware (but not others). These changes appear to prevent certain race conditions that may or may not cause USB problems. From Petteri Aimonen. * arch/arm/include/armv6-m and arch/arm/src/armv6-m: First cut at support for the Cortex-M0 * configs/nutiny-nuc120, arch/arm/include/nu1xx, and arch/arm/src/nuc1xx: Support for Nuvoton NuTiny NUC120. * 2013-02-22: the Cortex-M0, NuvoTron NUC1xx, and NuTiny-SDK-NUC120 port is code complete and ready for testing. * configs/ekk-lm3s9b96/ostest and nsh: All EKK-LM3S9B96 configurations converted to use the mconf configuration tool. * configs/zkit-arm-1769: Add support for Zilogic System's ARM development Kit, ZKIT-ARM-1769. From Rashid. * configs/zkit-arm-1769/hello: Add a "Hello, World!" configuration for the KBIT-ARM-1769 board. From Rashid. * configs/zkit-arm-1769/thttpd: Add a THTTPD configuration for the KBIT-ARM-1769 board. From Rashid. * 2013-02-27: All configurations for the Cortex-M0 NuTINY-SDK-NUC120 appear to be functional and stable. * configs/zkit-arm-1769/nsh: Add an NSH configuration for the KBIT-ARM-1769 board. From Rashid. * arch/arm/src/stm32/stm32_otgfsdev.c: Fixes from Petterri Aimonen related to corner cases that can cause infinite interrupts. * drivers/usbdev/usbmsc_scsi.c: Change to allow the full name in the USB descriptor but a truncated, 8-byte name in the SCSI field. From Petteri Aimonen. * arch/arm/src/stm32/stm32_spi.c: Need to clear error flags to prevent corruption of subsequent transfers. Also, bit count should not be changed while the SPI peripheral is enabled. From Petteri Aimonen. * drivers/mmcsd/mmcsd_spi.c: When bus is shared, the speed has to be set every time. Also SD cards require a few dummy clocks to react into CS release. From Petteri Aimonen. * configs/lm4f120-launchpad: In initial configuration for testing the LM4F120 LaunchPad port. This is to support testing only and is not yet a functional board port (as of 2013-03-01). * arch/arm/include/lm/lm4f_irq.h and arch/arm/src/lm/chip/lm4f_vector.h: Add interrupt vector/IRQ number definitions for the LM4F120. * arch/arm/src/stm32f20xxx_dma.c and stm32f40xxx_dma.c: Fix a typo in assigned base register addresses for each DMA channel. From Yan T. * Several build fixes from Mike Smith were incorporated. These were mostly compilation errors introduced into the system because of the large number of recent changes with broad scope (2013-03-04). * configs/zkit-arm-17969/src/up_can.c: Add CAN support to the Zilogics Technologies ZKIT-ARM-1769 board (From Rashid Fatah, (2013-03-04)). * arch/arm/src/lpc17/lpc17*_clockconfig.c: The WaveShare Open1788 board now boots and passes the OS test. This is the work of Rommel Marcelo (2013-03-04). * arch/arm/src/lm/lm_gpio.c, lm_gpio.h, and chip/lm4f_pinconfig.h Extend GPIO logic to handle LM4F. Add LM4F pin configuration header file (2013-03-04). * configs/open1788: Enable LED support in all configurations. (2013-03-04) * configs/open1788/nsh: NSH configuration verified function. By Rommel Marcelo (2013-03-05). * configs/open1788/src/lpc17_nsh.c: Use the SD card interface, not SPI to interface with SD cards (2013-03-05. * arch/arm/src/lpc17xx/lpc17_sdcard.c and header files: Clone the STM32 SD card interface to the LPC1788. It appears to be the same IP. (2013-03-05) * libc/wqueue: Work queue logic moved from sched/ to libc/wqueue. It is not really core OS functionality and this move helps prepare for user-space work queues. (2013-03-05) * libc/wqueue: Implemented user-space work queues. These will not get tested until the next time I attempt a NuttX kernel build. (2013-03-05). * arch/arm: Correct some bad syscall dispatching logic. This change cannot be fully tested until there is a fielded NuttX kernel build. (2013-03-06). * net/net_poll.c: Correct logic that checks if the socket is disconnected when the poll is setup. That is bad logic: Listen sockets, for example, are not connected. In that case, the purpose of the poll is to wait for connection events. As a result of this, poll/select would return immediately with POLLHUP with it was used to detect connection events. This fix for now was to check instead if the socket is closed (meaning that it was connected at one time but was closed by the remote peer). That excludes the listen socket which was never connected. This does introduce a new problem, however. If the socket was not closed, but lost the connection through an abnormal event, then poll/select will hang. That needs to be revisited. (2013-03-07) * fs/fs_select.c: Was not checking if the timeout parameter was NULL but would, instead, setup a bogus timeout based on whatever it found at address zero. Also, improved some of the memory allocation logic so that it will not use so much memory. (2013-03-07) * net/net_poll.c: Handle the missing case. Now tests for not connected AND not listening. I think that now covers all of the cases including the missing case noted above. (2013-03-07) * mm/: Move all memory manager globals into a structure. A reference to this structure is now passed internally between mm APIs. This change will (eventually) support multiple heaps and heap allocators. (2013-03-08). * mm/ and include/nuttx/mm.h: Implement support for multiple heaps. (2013-03-08). * arch/*/src: xyz_addregion() needs to call kmm_addregion, not mm_addregion. (2013-03-08). * sched/kmm*.c: Move this garbage kmm*.c file to mm/. until I decide what to do with them (which is probably to just delete them). (2013-03-08). * mm/mm_test.c and Makefile.test: Deleted the memory test. This was a good test and helped me a lot when I wrote the memory manager, but now it is in the way and paralyzing other efforts. So the memory unit test was deleted. (2013-03-08) * sched/sched_free.c: Rename sched_free() to sched_ufree(); Add sched_kfree() to handler deferred kernel heap allocations. (2013-03-10) * arch/: User user-accessible heap to allocate all stacks. (2013-03-10) * arch/arm/src/sam3u: The AT91SAM3U will now support a kernel heap if so configured. (2013-03-10) * configs/sam3u-ek/knsh: This configuration was converted to use the kconfigs-frontends build tool. (2013-03-10) * configs/*/include/user_map.h and include/nuttx/userspace.h: Remove the very kludgy user_map.h file and replace it with a header that is expected at the beginning of the user-space blob. (2013-03-10) * configs/sam3u-ek/kernel/up_userspace.c: This is the header for the SAM3U-EK's user space. (2013-03-10) * sched/os_bringup.c: In the kernel build, os_bringup() now uses the user-space header to automatically start the user-space work queue, if so configured. (2013-03-10) * arch/arm/src/lpc17xx/lpc17_mpuinit.c and lpc17_userpace.c: Add support for the MPU and kernel build for the LPC17xx family. (2013-03-11) * configs/open1788/kernel and knsh: Add kernel build support and a kernel NSH configuration for the WaveShare Open1788 board. (2013-03-11) * configs/sam3u_ek/kernel, knsh, and scripts: Move some files around for better supportability. (2013-03-11) * configs/open1788/kernel, knsh, and scripts: Add a kernel mode build configuration for the WaveShare Open1788 board. (2013-03-11) * arch/arm/src/armv7-m/up_mpu.c: Several fixes to MPU logic. (2013-03-12). * arch/arm, configs/sam3u-ek, configs/open1788: Fix memory map for kernel mode build; Some regions were overlapping. (2013-03-13). * arch/: Rename g_heapbase to g_idle_topstack. This is the same value however: The top of the IDLE stack is the same as the base of the heap in the flat build. But not in the kernel build: The base of the heap is elsewhere so the naming was wrong. (2013-03-13). * libc/stdlib/lib_itoa.c: Implementation of itoa() contributed by Ryan Sundberg. (2013-03-14). 6.27 2013-04-28 Gregory Nutt * arch/arm/src/armv7-m/up_mpu.c: Correct MPU sub-region settings for unaligned regions (2013-03-15). * arch/arm/src/armv6-m/up_svcall.c: Bring up to equivalent to the ARMv7-M version (2013-03-15). * configs/lm4f120-launchpad/tools: Add scripts and instructions to simplify use of OpenOCD with ICDI (from JP Carballo, 2013-03-15). * tools/mkconfig.c: Logic that attempts to suppress buffered I/O within the kernel is wrong. sizeof(struct file_struct) must be the same in both kernel- and user-spaces (2013-03-16). * arch/arm/src/common/up_pthread_start.c, libc/pthread/pthread_startup.c, and related files: Implement switch to user-space and user-space pthread start-up function (2013-03-16). * arch/arm/src/common/up_signal_handler.c, libc/pthread/pthread_startup.c, and related files: Implement switch to user-space and user-space pthread start-up function (2013-03-16). * arch/arm/src/common/up_signal_handler.c, libc/signal/signal_handler.c, arch/arm/src/armv[6|7]-m/up_svcall.c, arch/arm/include/armv[6|7]-m/svcall.h, include/nuttx/userspace.h, and sched/sig_deliver.c: Implement switch to user-space from kernel signal delivery trampoline before calling user- space signal handler. Return from user-space signal handler using a system call (2013-03-16). * arch/arm/src/armv[6|7]-m/up_schedulesigaction.c: Need make sure we are in kernel mode before switching to kernel-mode signal handler trampoline (2013-03-16). * arch/arm/include/armv[6|7]-m/irq.h, and arch/arm/src/armv[6|7]-m/up_svcall.c: Add support for nested system calls. In the current design, this can happen only under one condition: When the kernel system call logic calls back into user space in order to allocate user space memory. So it is expected that the maximum nesting level will be only 2 (2013-03-17). * libc/stdio/lib_sccanf.c: Correct an error in sscanf. If %n occurs in the format statement after the input data stream has been fully parsed, the %n format specifier will not be handled. Reported by Lorenz Meier (and also earlier by Kate) (2013-03-17). * drivers/serial/serial.c: Support for O_NONBLOCK was not supported in the "upper half" serial driver. This is normally not an issue because UART TX is almost always available, but it does become an if the UART uses hardware flow control or if the a "lower half" is something like the USB CDC/ACM driver that may need to block for significant amounts of time (2013-03-18). * arch/arm/src/armv7-h/ram_vectors.h, up_ramvec_*.c, arch/arm/src/*/*_irq.c, and Make.defs: Add support for modifiable interrupt vectors in RAM (2013-03-18). * arch/arm/src/armv7-m/up_exception.S, sam3u/sam3u_vectors.S, and lpc17xx/lpc17_vectors.S: In exception handling with CONFIG_NUTTX_KERNEL, need to explicity set and clear the privilege bit in the CONTROL register on return. I assumed this would be handled automatically by the EXC_RETURN. Silly me (2013-03-18). * arch/arm/src/lpc17_adc.c: Add a work-around for an ADC errata. From Chris Taglia (2013-3-19). * arch/arm/src/armv7-m/up_hardfault.c: If the PRIMASK is used to disable interrupts, then additional logic is required in the hard fault handler (2013-3-19). * libc/ and mm/: Directories where the same sources files are used to build different objects in the first and second pass kernel builds need to keep those objects in separate directories so that they are not constantly rebuilt (2013-3-19). * fs/fat: Create an error in FAT file creation. The FAT logic was not making a distinction between directory non-existence and file non-existence so when it you try to create a file in a non-existent directory, it would create a file with the name of the missing directory. Reported by Andrew Tridgell (2013-03-30). * Numerous files: Changed the protoypes of up_create_stack() and up_release_stack() so that is includes a task type. Normally you can get this type from the TCB parameter, but there are certain conditions when the task type is not valid in the TCB when these functions are called. Only the prototypes were changed on this big, initial checkin. The next step will be to add logic to allocate stacks for kernel threads from protected kernel memory and all other task types from unprotected user memory (2013-03-20). * arch/*/src/common/up_createstack.c, up_use_stack.c, and up_release_stack.c: If creating or releasing the stack for a kernel thread, use the kernel allocator so that the kernel thread stacks are protected from user application meddling (2013-03-20). * arch/arm/src/armv[6|7]-m/up_scall.c: Fix parameter passing for all system call inline functions with > 3 parameters (2013-03-20) * arch/*/src/common/up_stackframe.c and include/nuttx/arch.h: Add and new interface to set aside memory on the stack. This will be used at least in the kernel build to hold task arguments (2013-03-21). * sched/sig_deliver.c: When dispatching signals to user threads, copy the siginfo_t from the sigq to the stack. The signal queue is allocated from kernel memory; however, the current stack is the user's stack and the user code will be able to access the signinfo_t data from the stack copy (2013-03-21). * arch/arm/src/stm32: Added support for the kernel mode build (cloned from the lpc17xx). (2013-03-21). * configs/stme32f4discovery/kernel and scripts: Add support for the kernel mode build on the STM32F4Discovery (2013-03-21). * drivers/st7567.c/h and include/nuttx/lcd/st7567.h: Driver for the ST7567 LCD Display Module from Univision Technology Inc. contributed by Manikandan.S (2013-03-22). * configs/zkit-arm-1769: Now supports the ST7567 LCD display module. Added an nxhello configuration for testing (Manikandan.S, 2013-03-22). * configs/stm32f4discovery/kostest: Add a kernel mode version of the OS test for the STM32F4Discovery board (2013-03-22). * nuttx/include/nuttx, nuttx/configs/sam3u-ek, nuttx/configs/open1788, nuttx/configs/stm32f4discovery, and nuttx/arch/arm: Complete re-archtecting of how signals are dispatched to user-space code in the kernel build. The original implementation was C-based and simpler. However, the C code intermixed with SVC calls was not properly preserving registers. The more complex, assembly language version does not suffer from these issues. I believe the kernel build can now be called "feature complete" (2013-03-23). * binfmt/binfmt_execmodule.c: Here is a place where I forget to update the call to sched_releasetcb() to pass the thread type as the second parameter (2013-03-23). * arch/arm/src/lm, kinetis, lpc43, and nuc1xx: Add kernel build support to all ARMv7-M and ARMv6-M chips. There are no configurations in place to to verify these additions! (2013-03-24). * arch/arm/src/lm/lm_gpio.h: Correct typos in alternate function definitions (2013-03-24). * arch/arm/src/lm/lm_lowputc.c and lm_serial.c: Add support for the 7 UARTs on the LM4F120 (2013-03-24). * configs/lm4f120-launchpad/ostest/defconfig: Fix the configured RAM size. This appears to be the last show-stopper bug: The LaunchPad now runs NuttX! (2013-03-24). * configs/lm4f120-launchpad/nsh: Add an NSH configuration for the LaunchPad (2013-03-24). * configs/kwikstik-k40: Converted configurations to use the konfig-frontends tool (2013-03-25). * configs/twr-k60n512: Converted configurations to use the konfig-frontends tool (2013-03-25). * arch/arm/src/lpc17xx/lpc17_lcd.c: Add an LCD framebuffer driver for the LPC177x/8x family (2013-3-26). * arch/arm/src/lpc17xx/lpc17_emc.c and configs/open1788/src/lpc17_sdraminitialize.c: Began testing the Open1788 SDRAM. The SDRAM is basically functional, but there are failures with the SDRAM is stressed by the memory test at apps/example/ramtest (SDRAM support and the RAM test can be configured into the base configs/open1788/nsh configuration as described in configs/open1788/READMT.txt (2013-3-27). * configs/open1788/nxlines: Add a configuration to test both the Open1788 LCD and SDRAM which is used as a framebuffer (2013-3-27). * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: Began implementation of the LPC17 DMA and integration into the SDCARD driver (2013-3-29). * arch/arm/src/lpc17xx/lpc17_gdma.c: LPC17 DMA is code complete and under test. Does not yet work (2013-3-30). * fs/fat/fs_fat32dirent.c and fs_fat32util.c: Several fixes to the FAT file system from Ronen Vainish. These fixes mostly involve the logic to extend directory clusters for the case of long file names but also include a few important general fixes (such as for storing 32 bit FAT values) (2013-03-31). * arch/arm/src/lpc17xx/lpc17_gdma.c and lpc17_sdcard.c: SD card DMA is now functional. Thre may be some issues with DMA from CPU SRAM which is apparently disabled in sleep mode; up_idle() always enters sleep mode (2013-03-31). * arch/arm/src/stm32: Add architecure support for the STM32 F427/F437 chips. Contributed by Mike Smith (2013-4-01). * configs/zkit-arm-1769/src/up_can.c: Add support for both CAN1 and CAN2. Contributed by M.Kannan (2013-4-01). * arch/arm/src/lpc17xx/lpc17_spi.c and lpc17_ssp.c and configs/olimex-lpc1766stk, nucleus2g, zkit-arm-1769, and lpcxpresso-lpc1768: The initialization function for both the LPC17xx SPI and SSP blocks was called up_spinitialize() which is the common API definition of include/nuttx/spi.h. But this raises a problem when the MCU has multiple blocks for differ SPI implementations as does the LPC17xx (and also as does other architectures like STM32 that have USARTs that can serve as SPI interfaces as well). These were renamed to lpc17_spiinitialize() and lpc17_sspinitialize() in this case. Problem reported by M. Kannan (2013-4-01). * arch/arm/src/lpc17xx/lpc17_gpdma.c and lpc17_idle.c: In sleep mode, DMA can only be performed from peripheral SRAM. CPU SRAM is shutdown in sleep mode. In order to simplify DMA memory allocation, the LPC17xx IDLE will now hold off going to sleep mode if there is a DMA in progress (2013-4-01). * configs/open1788/src/lpc17_autoleds.c: Reversed sense of the IDLE LCD. It is now off when the LPC17 is sleeping and on when awake. That is much more useful because it provides a good visual indication of the dynamic CPU load (2013-4-01). * configs/open1788/src/lpc17_touchscreen.c and lpc17_ssp.c: Add support for the touschscreen on the WaveShare LCD (2013-4-01). * configs/several: There were already some functions called lpc17_sspinitialize(). So they had to be renamed (2013-4-01). * arch/arm/src/lpc17xx/lpc17_ssp.c: Adapted to work with the LPC178x family (2013-4-01). * arch/arm/src/lpc17xx/lpc17_gpio.c/.h: Separate LPC176x and LPC178x logic into separate files. The logic is diverging to much to try to retain common code (2013-4-03). * net/net_clone.c: Fix compilation error when socket options are are disabled. Reported by Daniel O'Connor (2013-4-05). * configs/zkit-arm-1769/src/up_leds.c: Fix a typo introduced into the button interrupt logic (2013-4-05). * arch/arm/src/lpc17xx/lpc178x_gpio.c: Re-design of the GPIO logic for the LPC178x family by Rommel Marcelo (2013-4-05). * arch/arm/src/lpc17_gpiodbg.c: Updated so that it correctly reports LPC177x/8x GPIO registers when GPIO debug is enabled (2013-4-05). * arch/arm/src/Makefile: The variable NUTTX already includes the extension $(EXEEXT). So remove the second extension $(NUTTX)$(EXEEXT) in two places (2013-4-7). * arch/arm/src/lpc17xx/lpc17_gpioint.c: Disable interrupts in lpc17_setintedge(). This logic must be atomic because it can be re-entered before it completes enabled interrupts, sometimes leaving the interrupts in a strange state (2013-4-7). * arch/arm/src/lpc17_lcd.c: Rommel Marcelo got the LPC1788 framebuffer-based LCD working. Very nice! (2013-4-08). * arch/arm/src/lm/lm_clockconfig.c and configs/lm4f120-launchpad: Fix handling of the RCC SYSDIV2 field when the PLL output is 400MHz. Don't forget to set the USERCC2 bit in the register or all is for naught (2013-4-09). * configs/zkit-arm-1769/src/up_lcd.c, up_ssp.c, and up_spi.c: Use SSP0 to LCD and SPI to SD-Card on the Zkit-arm-1769 board. From Manikandan. S (2013-4-10) * configs/olimex-lpc1766stk/usbserial: Converted to use the kconfig-config frontends tools (2013-4-12). * drivers/usbdev/pl2303.c: Fix some compilation errors that crept in when fixes to the CDC/ACM driver where blindly incorporated in the PL2303 driver (2013-4-12). * configs/stm3210e-eval/usbserial: Converted to use the kconfig-config frontends tools (2013-4-12). * configs/nucleus2g/usbserial: Converted to use the kconfig-config frontends tools (2013-4-12). * arch/arm/src/kl and arch/arm/include/kl: Add support for the Kinetis L family of Cortex-M0+ MCUs. Contributed by Alan Carvalho de Assis. NOTE: This is still very much a work in progress as of this initial commit (2013-04-16). * configs/freedom-kl25z: Support for the Freedom KL25Z board contributed by Alan Carvalho de Assis. NOTE: This is still very much a work inprogress as of this initial commit (2013-04-16). * arm/arm/src/armv6-m and arch/arm/include/armv6-m: Ooops. Fix a major screw-up: The Cortex-M0 has no BASEPRI register but the current logic was using it to manage interrupts. Switch to using the PRIMASK. This means that hardfaults will (again) occur when SVC instructions are executed (2013-4-16). * configs/stm3240g-eval/ostest: Converted to use the kconfig-frontends tools (2013-4-17). * sched/task_exithook.c: Don't flush the streams until the final thread of the group exits. Flushing may cause the thread to get suspended at a bad time and other threads in the group may run while the exiting thread is in an unhealthy state. This can cause crashes under certain circumstance. This is a critical bugfix (2013-4-18). * drivers/mtd/ramtron.c: Extended to support the FM25V01 device. Contributed by Lorenz Meier (2013-4-18). * sched/task_deletecurrent.c and task_exit.c, arch/*/up_exit.c: Renamed task_deletecurrent() and task_exit() since it really handles the architecture independent part of _exit(). _exit() is used internally, but if it is called from the user, it should unregister any atexit() or on_exit() functions (2013-4-18). * tools/kconfig2html.c: This is the beginning of a tool to replace the hand-generated documentation of the NuttX configuration variables with auto-generated documentation. The initial checkin is an incomplete, poorly structured prototype that I hope to evolve into a useful tool (2014-4-20). * libc/string/lib_strchr.c: strchr(str, '\0') should return a pointer to the end of the string, not NULL. From Petteri Aimonen (2014-4-22). * fs/fat/fs_writefat.c: mkfatfs was writing the boot code to the wrong location. From Petteri Aimonen (2014-4-22). * Documentation: The NuttX documentation now expects to find an auto-generated version of the configuration variable documentation at Documentation/NuttXConfigVariables.html (2014-4-22). * arch/arm/src/lpc17xx/lpc17_adc.c: Only one ADC pin was configured. Need to configure all that are in the ADC0 set. From MKannan (2014-4-23). * configs/zkit-arm-1769/src: ADC and SPI/USB MSC updates from MKannan (2014-4-23). * arm/src/armv7-m/ram_vectors.h and arm/src/armv7-m/up_ramvec_initialize.c: Fixes to RAM vector logic from Paul Y. Zhang (2014-4-23) * tools/kconfig2html.c: Improve behavior of Expand/Collapse Table of Contents; Handle errors in parsing of strings and in some uninitialized variables. Add an option to use jQuery. * tools/mkconfigvar.sh: Fix make target (2014-4-23). * sched/exit.c, pthread_exit.c, task_exit.c, task_delete,c and task_exithook.c: For pthread_exit(), move some logic to an early point in the exit sequence where the task may need to block. Add conditional logic in the lower end of the eixt logic kicked off by _exit() to prohibit blocking after the task has been torn down and is no longer cabable of blocking (2014-4-23). * arch/arm/src/common/up_initialize.c: Add missing registration of /dev/zero. Registration of /dev/null should depend upon conditional compilation. From Ken Pettit (2014-4-24). * arch/*/src/common/up_initialize.c: Same change required to other architectures (2014-4-24). * arch/arm/src/kl/kl_clockconfig.c and configs/freedom-kl25z/include/board.h: Modify out PLL configuration so that it uses the values in board.h; Fix PLL settings in board.h so that the correct core and bus clock frequencies are generated. (2014-4-24). * arm/src/kl/chip/kl_memorymap.h, kl_sim.h, andkl_uart.h: Correct some register definitions (2014-4-25). * arch/arm/src/kl/Kconfig, kl_lowputc.c, kl_serial.c, and kl_config.h: No UART3-5 (2014-4-25). * arch/arm/src/kl/kl_serial.c: Various fixes to various files in the KL architecture directory as need to get the interrupt-driven serial driver to work. The Freedom KL25Z NSH configuration now works (2014-4-25). * include/nuttx/assert.h, arch/*/src/*/up_assert.c, and other file: Remove up_assert_code(). While asserting with an encoded value could be a good feature, the codes have not be well utilized nor documented. Give that situation it is better to remove the API and reduce the footprint a little (2014-4-25). * drivers/serial/Kconfig and arch/*/src/*/*_serial.c: Add compilation so that the useless TIOCSERGSTRUCT ioctl logic is not build unless CONFIG_DEBUG and CONFIG_SERIAL_TIOCSERGSTRUCT are defined. * sched/task_delete.c and task_terminate.c: Most task_terminate() out of task_delete.c into its own C file. This should prevent dragging task_delete() into the link when it is never called. 6.28 2013-06-14 Gregory Nutt * arch/arm/src/lpc17xx/lpc17_i2c.c: Interrupts were not being re-enabled in the I2C initializeation function (2013-4-30). * net/sendto.c: Added skeleton of implementation of send timeouts for UDP. However, this functionality really does not make sense, so it is disabled in the code (2013-4-30). * drivers/mtd/mtd_partition.c: Support capability to clone one MTD driver into several, MTD partition drivers, each of which can manage a sub-region of the FLASH (2013-4-30). * configs/sim/nxffs: Converted to use the kconfig-frontends tools (20130-4-30). * configs/sim/mtdpart: A new configuration to test MTD partitions (2013-4-30). * configs/sim/mkroe-stm32f4: Support for the MikroElektronika Mikromedia for STM32F4 development board (from Ken Pettit, 2013-4-30). * fs/smartfs: Add Ken Pettit SMART FS (2013-4-30). * include/nuttx/mtd.h and most MTD drivers: Add support for (optional) method to perform byte oriented writes if so configured (2013-5-1). * arch/arm/src/kl/chip/kl25z128_pinmux.h: Corrections fo the pin multiplexing definitions from Alan Carvalho de Assis (2013-5-2). * drivers/mtd/mtd_partition.c: Fix a few bugs and add support for the (option) byte write method (2013-5-3). * arch/arm/src/kl: Repartitioning of definitions in header files from Alan Carvalho de Assis (2013-5-3). * drivers/mtd/smart.c, fs/smart, and other files: SMART file system now makes use of the MTD byte write capabilities when present (from Ken Pettit, 2013-5-3). * drivers/mtd/m25px.c: Some rearchitecting to use the byte write capability (when possible) and to use 4KB sectors for the erase block size when the part supports it (Ken Pettit, 2013-5-3). * configs/pirelli_dpl10: Adds a configuration for the pirelli phone (from Craig Comstock via Alan Alan Carvalho de Assis, 2013-5-3). * arch/arm/src/calypso: Fix some compilation warnings (2013-5-5). * configs/pirelli_dpl10/nsh_highram: Converted to use the kconfig-frontends tools (2013-5-5). * drivers/lcd/mio283qt2.c: LCD was not being selected in setpower method (also not being deselected in hwinitialize function) (2013-5-6). * arch/arm/src/kl/kl_gpio.c and .h, configs/freedom-kl25z/src/freedom-kl25z.h, and configs/freedom-kl25z/src/kl_led.c: Fixes LEDs on the Freedom KL25Z board (2013-5-6). * arch/arm/src/kinetis/kinetis_pin.c and arch/arm/src/kinetis/kinetis.h: The Kinetis GPIO logic had some of the same issues as did the Kinetis L (2013-5-6). * arch/arm/src/stm32/stm32_idle.c: Add an option to conditionally disable the "wfi" sleep mode. This is needed with certain JTAG debuggers to to prevent the debug session from begin disconnected. From Ken Pettit (2013-5-7). * configs/mikroe-stm32f4/fulldemo/, nx/, nxlines/, nxtext/: Add more configurations for the Mikroelektronika Multimedia STM32-M4 board.

From Max Holtzberg (2013-5-21). * audio/, drivers/audio, include/nuttx/audio: Added a callback interface to the Audio upperhalf driver for dequeueing, reporting async events, etc. Also included is some initial work for the VS1053 driver. From Ken Pettit (2013-5-21). * include/nuttx/audio/audio.h: Moved from include/nuttx/ to include/nuttx/audio. (2013-5-21). * configs/lm3s6965-ek/tcpecho: This configuration builds the simple TCP echo example based on W.Richard Steven UNIX Programming book to ensure correct usage of the socket API. Contributed by Max Holtzberg (2013-5-22). * configs/stm32ldiscovery/src/stm32_lcd.c: Framework for support of the STM32L-Discovery's segment LCD (2013-5-22). * fs/fs_poll.c: Poll setup/teardown logic should ignore invalid (i.e., negative) file descriptors. Max Holtzberg (2013-5-23). * net/net_poll.c: When readahead data is available, the network poll logic should set POLLIN (or POLLRDNORM), not POLLOUT. Max Holtzberg (2013-5-23) * fs/fs_poll.c: Actually, it should also set revents == 0. (2013-5-23). * libc/misc/lib_slcdencode.c and lib_slcddecode.c: Add logic to marshal and serialize special SLCD intermixed with normal ASCII data (2013-5-23) * configs/stm32ldiscovery/src/stm32_lcd.c: STM32L-Discovery's segment LCD is code complete but completely untested (2013-5-23). * include/nuttx/fs/ioctl.h, include/nuttx/lcd/slcd_codec.h, and configs/stm32ldiscovery/src/stm32_lcd.c: Add SLCD ioctl commands to get SLCD geometry, set bars, and manage contrast (2013-5-23). * configs/stm32ldiscovery/src/stm32_usb.c: This file and all references to USB removed for the STM32L-Discovery. While the chip supports a USB device, the board does not (2013-5-24). * arch/arm/src/stm32/stm32_lse.c: Add support for the STM32L CSR register and for the LSE LCD clock source (2013-5-24). * The STM32L-Discovery segment LCD is now functional and the README file includes instructions for adding the apps/examples/slcd segment LCD test as an NSH "built-in" command (2013-5-24). * configs/pcblogic-pic32mx: Converted all configurations to use the kconfig-frontends tool (2013-5-25). * configs/pcblogic-pic32mx/src: Renamed files using pic32mx_ vs up_ prefix. Enable building of LCD1602 LCD (2013-5-25). * configs/pcblogic-pic32mx/src/pic32mx_lcd1602.c: Now uses SLCD CODEC (2013-5-25) * configs/stm32ldiscovery/src/stm32_lcd.c: Now supports ioctl to get cursor position (2013-5-25). * include/nuttx/lcd/slcd_ioctl.h: Moved ioctls commands and structures from slcd_codec.h (2013-5-25) * libc/misc/lib_slcdencode.c and lib_slcddecode.c: Several encoding and decoding bug fixes (2013-5-26) * configs/sure-pic32mx: Converted all configurations to use the kconfig-frontends tools, cleaned up the directory structure and naming to match some of the more recent configurations, and added a segment LCD driver for the board. The initial checkin of the LCD driver is just a clone of configs/pcblogic-pic32mx/src/pic32mx_lcd1602 and it not yet expected to be functional (2013-5-26). * include/nuttx/lcd/slcd_ioctl.h and all SLCD drivers: Rename geometry structure to attributes; Move MAX contrast to attributes. Add attribute and ioctl commands to get and set LCD brightness (2013-5-27). * configs/sure-pic32mx/pic32mx_lcd1602.c: This driver appears to fully functional (at least to the extent that it has been tested) (2013-5-27). * arch/mips/src/pic32mx/pic32mx-usbdev.c: Fix NULL packet handling in the PIC32 USB device driver. Without this fix the CDC/ACM driver cannot be used reliably with the PIC32 USB. With this change the configs/sure-pic32mx/usbnsh configuration works great (2013-5-28). * configs/sure-pic32mx/src/pic32mx_nsh.c: The NSH configurations will support the USB monitor applications (2013-5-28). nuttx/arch/arm/include/stm32/chip.h, src/stm32/Kconfig, src/stm32/chip.h, and src/stm32/chip/stm32f103c_pinmap.h: STM32F103C4 and F103C8 chip support from Laurent Latil (2013-5-28) * configs/stm32_tiny: Add support for the STM32 Tiny development board based on the STM32 F103C8T6 MCU (2013-5-28). * arch/arm/src/stm32/stm32_usbdev.c: Fix an error in NULL packet handling: If the NULL-packet needed flag ever gets set, then it is not cleared and inifinite NULL packets result. This only effects the CDC/ACM class and was the cause of the failure of configs/stm32f3discovery/usbnsh configureation which works great after this change (2013-5-29). * drivers/usbdev/cdcacm.c and pl2303.c and include/nuttx/usb/cdcacm.h: Change the default IN request buffer size from 64 to 96. This will avoid requests of exactly MAXPACKET size and, hence, avoid so many NULL packets. Also, fix the OUT request buffers size to exactly the max packet size. It cannot be any other size (2013-5-29). * .gitignore: Clean-up of most all .gitignore files: Make scope of ignore to be only the current directory; Ignore .dSYM files in directories where .exe's may be build. Also, in Makefiles, clean .dSYM files in directories where .exe may be built (2013-5-30). * drivers/wireless/nrf24101.c/.h and include/nuttx/wireless/nrf24101.h: Add new driver for the wireless nRF24L01+ transceiver. From Laurent Latil (2013-6-1). * drivers/wireless/cc1101: Move files in the cc1101 up one directory. From Laurent Latil (2013-6-1). * configs/stm32_tiny: Fix nRF24L01+ driver integration for the STM32 Tiny. From Laurent Latil (2013-6-01). * configs/sam3u-ek: All remaining configurations changed to use the kconfig-frontends tools (2013-6-2). * arch/arm/src/sam3u/chip: All SAM3U register definition files moved to this subdirectory. Naming of registers changed from SAM3U_ to just SAM_. This is in preparation for a SAM4L port (2013-6-2). * arch/arm/src/sam3u: Renamed files to sam_* vs. sam3u_*. Eliminated sam3u_internal.h; instead uses individual header files for each SAM interface block (2013-6-2). * arch/arm/src/stm32/stm32f20xxx_rcc.c and stm32f40xxx_rcc.c, and configs/mikroe-stm32f4/src/up_clockconfig.c. Correct some bad conditional compilation (CONFIG_ missing from setting name). This affects some STM32 FLASH pre-fetch settings. From Lorenz Meier (2013-6-2). * arch/arm/include/sam34 and arch/arm/src/sam34: The old sam3u/ directories were renamed sam34/ to make room in the namespace for the SAM4L (2013-6-2). * libc/stdio/lib_dprintd.c and lib_vdprintf.c: Add dprintf() and vdprintf() (the latter from Andrew Tridgell, 2013-6-2). * sched/sem_holder.c: Modify assertion that is reported to cause false alarm assertions (2013-6-2). * arch/arm/include/sam34/sam4l_irq.h and arch/arm/src/sam34/chip/sam4l_memorymap.h: Add interrupt and memory map definitions for the AT91SAM4L (2013-6-3). * arch/arm/src/sam34/chip/sam4l_vectors.h and arm/src/sam34/sam_vectors.S: Add interrupt vector support for the SAM4L family (2013-6-3). * arch/include/sam34/chip.h: Add chip definitions for the SAM4L family (2013-6-3). * configs/sam4l-xplained: A partial configuration that will (eventually) support the SAM4L Xplained Pro developement board (2013-6-3). * arch/arm/src/sam34/chip/sam4l_pinmap.h: Initial cut as SAM4L pin mapping (2013-6-3). * arch/arm/src/stm32/stm32*_dma.*: Add a new interface function, stm32_dmacapable() that can be used to determine if DMA is possible from the specified memory address. From Petteri Aimonen (2013-6-4). * arch/arm/src/stm32/stm32_spi.c: If CONFIG_STM32_DMACAPABLE is defined, use stm32_dmacapable() to determine if it is possible to perform DMA from the specified address. This change is important for the STM32 F4 which may have SPI data buffers allocated on the stack in CCM memory which cannot support the DMA. From Petteri Aimonen (2013-6-4). * nuttx/arch/arm/src/sam34/sam4l_gpio.h: Created GPIO driver header file for the SAM4L.

Remove all other variants of the build-as-an-NSH-application configuration settings (2013-6-12). * arch/arm/src/sam34/sam_periphclks.h: A header file that just includes the right header file. This cleans up the messy logic in all of the C files and puts the mess in one place (2013-6-12). * arch/arm/src/arm*/Toolchain.mk, Kconfig (and lots of configuration files): Add support for a generic Windows EABI toolchain (2013-6-13). 6.29 2013-07-31 Gregory Nutt * arch/arm/src/sam34/chip/sam4l_pinmap.h: Change naming of some pin configurations to match names used with other SAM part (2013-6-15). * arch/arm/src/sam34/sam4l_clockconfig.c: Corrected some typos (2013-6-15). * configs/sam4l-xplained/src/sam_buttons.c: Eliminate a warning (2013-6-15). * configs/sam4l-xplained/src/sam_mmcsd.c, sam_nsh.c, sam_spi.c, sam3u-ek.h, Kconfig, Makefile, sam4l-xplained.h, configs/sam4l-xplained/README.txt, and configs/sam4l-xplained/include/board.h: Add support for the SPI- based SD card on the I/O1 module (2013-6-15). * arch/arm/src/sam34/sam_spi.c: Re-architect the SAM3/4 SPI driver so that is it compatible with the SPI drivers of other MCUs (2013-6-16). * configs/sam3u-ek/src/up_touchscreen.c and configs/sam4l-xplained/src/sam_mmcsd.c: Changed needed because of the above change to the SAM3/4 SPI interface (2013-6-16). * drivers/input/ads7843e.c: Remove the wait for the touchscreen busy bit. I don't see the busy bit changing on the SAM3U-EK board. But maybe it is not supposed to. From my reading of the ADS7843 spec, it would not be appropriate to wait for the BUSY bit to de-asserted anyway (since it is only de-asserted when we read the data) (2013-6-16). * configs/sam3u-ek/src/up_touchscreen.c: Fix polarity of the /PENIRQ signal (it is active low) (2013-6-16). * configs/sam3u-ek/include/board.h: The SAM3U-EK board now runs at 96MHz.

Taken from work by Alan Carvalho de Assis (2013-6-20). * arch/arm/src/kl/kl_dumpgpio.c: Now compiles (2013-6-20). * configs/: Several defconfig files were changed that had CONFIG_HAVE_CXXINITIALIZE=y. Because of recent changes to apps/examples, these configurations may need to have CONFIG_EXAMPLES_NSH_CXXINITIALIZE=y so that they behave as they did before, i.e., so that C++ initializers will be called when NSH starts up (2013-6-21). * configs/sam4l-xplained/src/sam_slcd.c: Beginning of a driver for the LED1 segment LCD module. This driver is incomplete on initial check- in (2013-6-21). * drivers/net/enc28j60.c: Change buffer ordering to work around Errata #5.

Apparently the same endpoint can be allocated as both an IN or an OUT endpoint. The existing implementation only supported one allocation, either IN or OUT. This resulted in failures to allocate endpoints when used with the CDC/ACM + MSC composite driver (From Chia Cheng Tsao, 2013-7-8). * arch/arm/src/stm32/stm32_sdio.c: SourceForge bug #17: Add support for the data block end (DBCKEND) interrupt to terminate transfers (From Chia Cheng Tsao, 2013-7-8) * drivers/rwbuffer.c: SourceForge bug #17: Correct typos that can cause failures in some configurations (From Chia Cheng Tsao, 2013-7-8). * include/nuttx/usb/usbdev.h: Fix some typos that cause compiler errors when CONFIG_USBDEV_DMA and CONFIG_USBDEV_DMAMEMORY are selected (From Chia Cheng Tsao, 2013-7-12). * nuttx/configs/olimex-lpc1766stk/zmodem: Add a new configuration to test the Zmodem sz and rz commands (which don't actually exist yet, but will). (2013-7-12). * arch/arm/include/armv7-a and src/armv7-a: Beginning to add support for the ARMv7-A, the Cortex-A5 in particular. The initial checkin is only fragmentary: A few header files and some copied ARM9 assembly files. More to come (2013-7-18). * arch/arm/include/sama5, arch/arm/src/sama5, and configs/sama5d3x-e: Add a directory framework to support the Atmel AT91SAMA5D3 family and the SAMA5D3x-EK board(s) in particular. There is very little here on the first check-in, this structure is being used now primarily to create the Cortex-A5 support (2013-7-19). * arch/arm/src/armv7-a/arm_cache.S: Cortex-A5 cache operations (2013-7-20). * /arch/arm/src/armv7-a/arm_fpuconfig.S and fpu.h: A few more files for the ARMv7-A/Cortex-A5 port (2013-7-21). * arch/arm/src/sama5/sam_boot.c, sam_clockconfig.h, sam_lowputc.h, and sam_timerisr.c: A few more files for the SAMA5D3 port (2013-7-21). * configs/sama5d3x-ek/src/sam_autoleds.c: A few more files for the port to the SAMA5D3x-EK board (2013-7-21). * arch/arm/src/sama5/sam_irq.c: SAMA5 interrupt handling logic (2013-7-22). * arch/arm/src/sama5/sam_clockconfig.c: Add SAMA5 PLL configuration logic (plus associated header files).

(2013-7-22). * arch/arm/src/sama5/chip/sama5d3x_pinmap.h: Add pin multiplexing definitions for the SAMA5D3 (2013-7-23). * arch/arm/src/sama5/chip/: New header files for SAMA5 AXI Matrix SFR, and BSC blocks (2013-7-23). * arch/arm/src/armv7-a/arm_vectors.S: Force 8-byte stack alignment in interrupt handlers before calling C code. Other ARM architectures need to do this as well (2013-7-23). * arm/src/armv7-m/up_copyarmstate.c and armv7-a/up_copyarmstate.c: Added a new form of the register copy function that should save quit a bit of time for armv7-m (without common vectors) and with armv7-a (2013-7-23). * arch/arm/src/armv7-a/arm_restorefpu.S, arm_savefpu.S, arm_doirq.c, arm_fullcontextrestore.S, arm_saveusercontext.S: Add hardware floating point register save/restore logic for the Cortex-A5 (2013-7-23). * arch/Kconfig: Attempt at generic external memory configuration is not flexible enough, especially for the SAMA5. Move external memory configuration options from arch/Kconfig to arch/arm/src/lpc17xx/Kconfig, lpc31xx/Kconfig, sam34/Kconfig, and sama5/Kconfig and renamed each from CONFIG_ARCH_ to, for example, CONFIG_LPC31_. This renaming also affect many defconfig files (2013-7-24). * arch/arm/src/sama5/Kconfig and sam_allocateheap.c: Set up configuration options for SAMA5 external memory regions; add a custom sam_allocateheap.c to add the various configured memory regions to the heap (2013-7-24). * configs/sama5d3x-ek/src/sam_buttons.c, sam_userleds.c, and sam_autoleds.c: Add support for the buttons and LEDs on-board the SAMA5D3x-EK (2013-7-24). * configs/sama5d3x-ek/ostest/defconfig: Switch console to USART1 (2013-7-4). * arch/arm/src/sam34/Kconfig and drivers/serial/Kconfig: All serial configuration logic for USARTs needs to depend on if the USART is configured as a UART or not. And this is for all CPUS, not just SAM3/4 (2013-7-24). * arch/arm/src/arm/up_head.S and arch/arm/src/armv7-a/arm_head.S: Fix a bug (uninitialized register error) that crept in the ARM9 boot-up code several years ago and was cloned into the Cortex-A5 code. Obviously no one has used the ARM9 NuttX port for years! * Many files: Finally... I changed the naming of configuration variables like CONFIG_DRAM_ to CONFIG_RAM_. This has bothered me for a long time since most boards don't have DRAM. The more generic RAM naming should not produce so much cognitive dissonance (2013-7-26). * configs/sama5d3x-ek/hello: Added a tiny hello world configuration to simplify bring up of the SAMA5 (it will probably be removed later) (2013-7-26). * The sama5d3x-ek/hello now runs correctly (2013-7-28). * configs/sama5d3x-ek/ostest/: This configuration has been modified to run out NOR flash. More work is still needed to reconfigure the SMC so that the NOR flash can work with the high clock (2013-7-28). * arch/arm/src/sama5/sam_clockconfig.c/h and configs/sama5d3x-ek/src/sam_norflash.c: Add a file structure that will (eventually) support reconfiguration of NOR flash when NuttX boots from NOR FLASH (2013-7-29). * arch/arm/src/sama5/chip/sam_hsmc/h: SAMA5 HSMC register definition file (2013-7-29) * configs/sama5d3x-ek/src/sam_norflash.c: Add board specific logic to re-configure the SAMA5D3x-EK NOR FLASH before while running out of NOR FLASH. We need to change the NOR FLASH timing BEFORE increasing the main clock (2013-7-29). * configs/sama5d3-ek/norboot and src/nor_main.c: The norboot configuration to help debug NuttX in NOR flash. It runs out of ISRAM, configures NOR FLASH, then waits for you to break in with a debugger to start the program in NOR FLASH (2013-7-29). * arch/arm/src/armv7-a/arm_cache.S: Separate the bigger cache operations into separater files (2013-7-29). * arch/arm/src/stm32/stm32_dac.c: Fixed numerous DAC driver errors and added support for DAC DMA (contributed by John Wharington, 2013-7-30). * arch/arm/src/stm32/stm32f30xx_i2c.c: An I2C driver for the STM32 F3 family from John Wharington (2013-7-30). * arch/arm/include/armv7-m: Add irqdisable() (2013-7-30); * configs/sama5d3-ek/src/nor_main.c: Now disables interrupts before jumping to NOR flash (2013-7-30). * configs/sama5d3-ek/nsh: Add an NSH configuration for the SAMA5D3x-EK (2013-7-31) * configs/sama5d3-ek/src/sam_cxxinitialize.c: Add C++ support (2013-7-31). 6.30 2013-09-14 Gregory Nutt * arch/arm/src/sama5/arm_pghead.S: Separate the logic that is enabled by CONFIG_PAGING out of arm_head.S. That was just too much conditional compilation to be supportable (2013-8-1). * arch/arm/src/sama5/arm_head.S: Setup page table mappings for all of .text, .bss, .data, stacks and heap before enabling the MMU and caching. This is safer because it avoids the caching issues (and much less redundant) (2013-8-1) * arch/arm/src/sama5/chip/sam_mpddrc.h: Add DDR controller registers definitions for the SAMA5 (2013-8-1). * nuttx/configs/sama5d3x-ek/src/sam_sdram.c: Add logic which will (eventually) support the SDRAM on the SAMA5D3x-EK board. Initial commit is untested and incomplete (2013-8-1). * arch/arm/src/armv7-a/arm_mmu.c: Move some generic MMU logic out of SAMA5-specific code into this share-able file (2013-8-2) * arch/arm/src/armv7-a/mmu.h: Add inline functions to invalidate a single TLB. * arch/arm/src/sama5/sam_allocateheap.c and chip/sama5d3x_memorymap.h: Add logic to handle signed overflow when a memory region is greater than or equal to 2GB (2013-8-2). * arch/arm/src/sama5/sam_boot.c: Boot logic now initially configures DRAM as strongly ordered so that it can be initialized. After initialization, the page table entries are modified so that DRAM is fully cache-able (2016-8-2). * arch/arm/src/sama5/chip/sam_mpddrc.h: Correct typos in the SAMA5 DDR controller register definitions (2013-8-2). * arch/arm/src/sama5/sam_irq.c: Correct handling of spurious interrupts (2013-8-3). * arch/*/src/*/*_irq.c: Standardize configuration variables used to enable interrupt controller debug output (2013-8-3). * arch/arm/src/sama5/chip/sam_dmac.h: Add register definitions for the SAMA5 DMA controller (2013-8-3). * arch/arm/src/sama5/sam_dmac.c and sam_dmac.h: Add support for the SAMA5 DMAC controllers. Initial check-in is untested and is a straight leverage from the SAM3/4 (2013-8-4). * arch/arm/src/sama5/sam_spi.c, sam_spi.h, and chip/sam_spi.h: Leverage SPI support from SAM/3/4. Initial check-in is untested and have several limitations: No DMA, no SPI1 support (2013-8-4). * arch/arm/src/sama5/sam_spi.c and sam_spi.h: Now supports SPI1 and a register access debug option (2013-8-4). * configs/sama5d3x-ek/src/sam_spi.c: Add board support for the AT25 serial flash (2013-8-4). * configs/sama5d3x-ek/nsh/defconfig: FAT file system support is now enabled by default (2013-8-5) * configs/sama5d3x-ek/src/sam_nsh.c: Automatically mount AT25 file system for NSH if so configured (2013-8-5). * configs/sama5d3x-ek/src/sam_nsh.c: Verified that the AT25 FLASH works on the SAMA5D3x-EK boards and can support a FAT file system (2013-8-5). * arch/arm/src/sam34/sam_spi.c: Corrected an error in the SAM3/4 SPI driver while testing the SAMA5 SPI driver: If CONFIG_SPI_OWNBUS is not set, the driver will not configure the SPI mode correctly (2013-8-5). * configs/sama5d3x-ek/src/sam_at25.c: Move AT25 initialization logic out of sam_nsh.c and into a separate file where it can be better shared (2013-8-5). * arch/arm/src/sama5/sam_hsmci.c, sam_hsmci.h, and chip.sam_hsmci.h: Add register definitions and a driver for the (3) HSMCI memory card interfaces provided by the SAMA5. Leveraged from the SAM3/4 and untested on initial commit (2013-8-5). * nuttx/configs/sama5d3x-ek/src/sam_hsmci.c and sam_nsh.c: Add support for the (2) SD card slots provided on the SAMA5D3x-EK boards. Untested on initial commit (2013-8-5). * arch/arm/src/sama5 and nuttx/configs/sama5d3x-ek: Massive renaming to get consistent once and for in the usage of PIO vs GPIO. Other platforms use the term GPIO more, but Atmel prefers PIO. I prefer consistency. Also fixed CONFIG_PIO vs CONFIG_SAMA5_PIO and renamed files sam_gpio.* to sam_pio.* (2013-8-6). * arch/arm/src/sama5/sam_pioirq.c: Add support for SAMA5 PIO interrupts (2013-8-6). * configs/sama5d3x-ek/src/sam_hsmci.c: Add support for SD slot card detection PIO interrupts (2013-8-6). * arch/arm/src/sam34/sam_hsmci.c and sama5/sam_hsmci.c: Fix handling of some masked status conditions that can cause false-alarm errors (2013-8-6). * arch/arm/src/sama5/sam_dmac.c and sam34/sam34_dmac.c: For SAMA5, correct some bad register address and some bad assertions that caused false alarms. These latter were backported to the SAM34 DMAC driver as well (2013-8-6). * arch/arm/src/sama5/sam_dmac.c and sam34/sam34_dmac.c: Correct some parameters reversed in function call (2013-8-6). * arch/arm/src/sama5/sam_spi.c: The SAMA5 SPI driver now supports DMA transfers (2013-8-9). * arch/arm/src/sama5/sam_dmac.c: Finally after many bugfixes (the last being caching issues), the SAMA5 DMA support has been verified (with SPI) (2013-8-9). * arch/arm/src/sama5/sam_memories.c and .h: Centralize logic for conversions between physical and virtual addresses (2013-8-9). * arch/arm/src/sama5/sam_hsmci.c and sam34/sam_hsmci.c: Correct a race condition in the SAMA5 HSCMI driver: The transfer done interrupt was firing before the wait was started. Fix this and also backported the changes to SAM3/4 (untested). Now HSCMI is functional on the SAMA5 with DMA! (2013-8-10). * arch/arm/src/sam34/sam3u_periphclks.h: Correct a typo in a register name (2013-8-10). * drivers/mmcsd/mmcsd_sdio.c: Correction for a bad return value when multiple block SDIO transfers are suppressed. By Andrew Tridgell via Lorenz Meier (2013-8-10). * drivers/serial/serial.c, drivers/usbdev/cdcacm.c, and include/nuttx/fs/ioctl.h: Added support for FIONREAD and FIONWRITE, added TERMIOS input / output processing support for UART and CDCACM serial ports. Implemented by Mike Smith, Andrew Tridgell and Lorenz Meier (2013-8-10). * drivers/usbdev/cdcacm.c: Added FIONREAD and FIONWRITE to CDC/ACM driver based on serial.c implementation. From Lorenz Meier (2013-8-10). * arch/arm/src/stm32/Kconfig and stm32_serial.c: Added option to disable serial port reordering. From Lorenz Meier (2013-8-10). * arch/arm/src/sama5/Kconfig, sam_ohci.c, and arch/arm/src/sama5/sam_clockconfig.c: Add a OHCI driver for the SAMA5. Untested on initial check-in (2013-8-11). * include/nuttx/usb/usbhost.h, arch/arm/src/stm32, arch/arm/src/lpc17xx, and include/nuttx/usb/usbhost.h, and nuttx/configs/: Move prototype of usbhost_initialize() of usbhost.h and into architecture specific files. This is necessary because some chips (like the SAMA5) have multiple, different USB host interfaces (2013-8-11). * drivers/usbhost/usbhost_hidkbd.c and usbhost_storage.c: Correct some compilation errors when pre-allocated class structures are used. Also eliminate some warnings about uninitialized variables (2013-8-11). * configs/sama5d3x-ek/src/sam_usb.c and related files: Add support for initialization of the USB host and mass storage class device (2013-8-11). * arch/arm/src/sama5/sam_ohci.c and sam_usbhost.h (was sam_ohci.h), and configs/sama5d3x-ek/src/sam_usb.c, and sama5d3x-ek.h: Add controls to enable VBUS power in OHCI host most (2013-8-12). * includes/nuttx/usb/usbhost.h, all USB host drivers in arch/, and all USB host-side connection monitoring threads in configs/*/src: The SAMA5 has three downstream ports; all of the other USB host implementations have only one. This will require significant changes to the USB host interfaces starting with these chnages to monitor connections on a port-by-port basis. This effects a lot of files and more changes are coming for this issues. Changes are being blindly incorporated into other architrectures. I am being careful to avoid breakage, but I expect some (2013-8-12). * configs/olimex-stm32-p107/nsh/defconfig and appconfig: Converted to use the kconfig-frontends tool. From Max Holtzberg (2013-8-12). * includes/nuttx/usb/usbhost.h, et al: Continued changes to the USB host interface to support multiple downstream ports. When a class is disconnected, it needs to provide the FunctionAddress to the USB HCD disconnect method so that the HCD will know which port is being disconnected (2013-8-12). * nuttx/arch/arm/src/stm32/Kconfig, Make.defs, and /stm32f30xxx_i2c.c: STM32 F3 I2C fixes from John Wharington (2013-8-13). * nuttx/arch/arm/src/sama5/sam_serial.c: Fix a re-entrancy problem in up_putc(). I think all architectures have this re-entrancy than can result in serial interrupt being disabled, but I have only seen the symptom on SAMA5 (2013-8-13). * includes/nuttx/usb/usbhost.h and many other affected files: Separate wait() and enumerate() methods from struct usbhost_driver_s and move to new interface, struct usbhost_connection_s. This is part of the necessary restructuring of the USB host interface to support multiple root hub ports (2013-8-13). * arch/arm/src/sama5/sam_ohci.c: Major restructuring of the driver due in order to handle multiple root hub ports. Basically instead of one driver structure with an arrayof root hub port structures, there is no one container structure with an array of driver structures, one for each root hub port. The advantage is that each class->driver call not passes information associated with the RHport implicitly. The klugey, procedural alternative was to add the function address to every interface method (which I started to do but backed above) (2013-8-13). * arch/arm/src/sama5/sam_memories.c and .h: Extended logic so do conversions from physical to virtual addresses (2013-8-14). * arch/arm/src/sama5/sam_ohci.c: Add D cache contols and conversion between physical and virtual address (2013-8-14). * arch/arm/src/stm32/stm32_spi.c: nbits() interface extended to control bit order as well as bit width (from Teemu Pirinen) (2013-8-16) * arch/arm/src/sama5/sam_ohci.c: More to be tested, but the SAMA5 OHCI driver is now basically funtional (2013-8-16). * include/nuttx/usb/ehci.h: EHCI header file (2013-8-17). * arch/arm/src/stm32/stm32_i2c.c: Correct an error that crept into the STM32 F1 I2C driver with some recent changes. From Yiran Liao (2013-8-18). * drivers/usbhost/usbhost_devaddr.c and include/nuttx/usb/usbhost_devaddr.h: Add logic for management of device addresses. This logic does not currently hook into into anything. It will someday be a part of the NuttX USB hub implementation (2013-8-18). * nuttx/arch/arm/src/sama5/sam_ehci.c and other files: Create a skeleton environment for development of an EHCI driver. Not much in place yet (2013-8-20). * nuttx/arch/arm/src/sama5/sam_ehci.c: Now code complete for all asynchronous endpoints (control and bulk); nothing yet in place for periodic endponts (interrupt and isochronous) (2013-8-22). * include/nuttx/serial/serial.h and arch/arm/src/stm32/chip/stm32f40xxx_pinmap.h: SourceForge bug #16 Fix IO pin map. Add CONFIG_SERIAL_TERMIOS support. Also fixes some STM32 F4 Timer 8 pin configurations. From CCTSAO (2013-8-23). * arch/arm/src/lpc17xx/lpc17_usbhost.h: Fix #endif with missing #if condition. Reported by Andrew Bradford (2013-8-23). * nuttx/arch/arm/src/sama5/sam_ehci.c: Now handles low- and full-speed connections by giving the port to the OHCI driver (2013-8-24). * nuttx/arch/arm/src/sama5/sam_ohci.c: Now uses the work queue to defer interrupt processing (2013-8-24). * nuttx/arch/arm/src/sama5/sam_ohci.c and nuttx/arch/arm/src/sama5/sam_ehci.c: EHCI is now the common interrupt "master." It will receive all UHPHS interrupts and route the interrupt event to both the OHCI and EHCI logic (2013-8-24). * net/uip/uip_arp.c: Correct backward condition in netmask task. From Max Holtzberg (2013-8-25). * arch/arm/src/sama5/sam_ohci.c: SAMA5 OHCI is again functional by itself after all of the changes to integrate with EHCI. (2013-8-25). * drivers/net/encx24j600.c/.h and include/nuttx/net/encx24j600.h: Support the Microchip ENCX24J600 Ethernet driver from Max Holtzberg (2013-8-25). * configs/olimex-stm32-p107: Incorporate ENCX24J600 support for the Olimex STM32 P107 board. From Max Holtzberg (2013-8-25). * fs/romfs/fs_romfsutil.c: Fix an error where long (>15) file names were read incorrectly from a ROMFS file system. From Mike Smith (2013-8-25). * arch/arm/src/stm32/stm32_sdio.c: SourceForge bug #17 Fix if CONFIG_SDIO_BLOCKSETUP defined, OS will crash". Generate an error if CONFIG_SDIO_BLOCKSETUP is defined; that option is not yet supported by the STM32 SDIO driver. From CCTSAO (2013-6-26) * drivers/net/encx24j600.c and .h: Use the ENC's SRAM for multiple TX packets. From Max Holtzberg (2013-6-26). * include/nuttx/usb/usbhost.h, drivers/usbhost/usbhost_enumerate.c, and all USB host drivers: Added a new driver method: getdevinfo. This method is intended to get various information about the connected device, but currently returns only the device speed. The device speed is necessary by usbhost_enumerate in order to set a credible initial EP0 max packetsize. High speed needs 64 bytes, low speed needs 8 bytes, and full speed can handle almost any size (2013-8-26). * arch/arm: Add hooks for Cortex-A8. Not much more yet (2013-8-27). * Lots of files: Fix all occurrents of "the the" in documentation and comments (2013-8-27). * arch/arm/src/sama5/sam_allocateheap.c: Correct the logic that determines which memory regions get added to the heap. When CONFIG_MM_NREGIONS > 1, the logic was adding the ISRAM region to the heap twice! (2013-6-27). * nuttx/arch/arm/src/sama5/sam_ehci.c: Add (untested) support for interrupt endpoints (2013-8-28). * arch/arm/src/sama5/chip/sam_udphs.h: High-speed USB device register definitions for the SAMA5 (2013-8-28) * arch/arm/src/sama5/sam-udphs.c: A framework for the USB device driver taken from another architecture. There is very little useful in this initial check-in (2013-8-29). * Remove all empty and most useless README.txt files (2013-8-31) * configs/freedom-kl25z/src/kl_spi.c: Correct typo in name of a function. From Alan Carvalho de Assis (2013-8-31). * drivers/usbdev/cdcacm_desc.c: Fixed some compilation errors that only occur when dual speed support is enabled (2013-9-1). * arch/arm/src/sama5/sam_clockconfig.c and configs/sama5d3x-ek/include/board_*mhz.h: Add logic to support UDPHS clocking (2013-9-13). * arm/src/stm32/chip/stm32_tim.h: Some CCER bit settings changed per SourceForge bug #18 submitted by CCCTSAO (2013-9-2). * apps/examples/cc3000, configs/freedom-kl25z, drivers/wireless/cc3000, and nuttx/include/nuttx/cc3000. Initial support for the TI CC3000 network module on the Freescale Freedom-KL25Z board from Alan Carvalho de Assis. This is still very much a work in progress (2013-9-3). * configs/*/usbmsc: Renamed from config/*/usbstorage to match the change in naming in apps/examples submitted by CCTSAO (2013-9-5). * drivers/usbdev/cdcacm.c and pl2303.c: Don't use max packetsize assigned to the endpoint when allocating request buffers; The default value of the endpoint max packetsize may be incorrect because the endpoint has not yet been configured. Verified on CDC/ACM. Corresponding changes made to pl2303, but untested (2013-9-5). * arch/arm/src/sama5/sam_udphs.c: The high-speed device side driver is now functional (although more testing is always needed) (2013-9-5). * net/net_monitor.c: Fixes a race condition where a loss of connection may not be detected when the connection is lost before it has been accepted (from Max Holtzberg) (2013-9-6). * configs/sama5d3x-ek/demo: Add a new NSH configuration. The original NSH configuration will be a simple platform for testing individual features; the demo configuration will be a more complex platform for demonstrating multiple interacting features (2013-9-6). * net/uip/uip_tcpbacklog.c: Fix a major bug in the TCP/IP backlog initialization: Only the first backlog buffer was getting added to the free list. From Max Holtzberg (2013-9-6). * configs/sama5d3x-ek/demo: Add support for USB MSC device on the AT25 serial FLASH (untested) (2013-9-6). * drivers/net/enc28j60.c: Changes back-ported from the ENCX24J600 to the ENC28J60 by Max Holtzberg. These seem like reasonable and correct changes, but have yet to be verified on an ENC28J60 (2013-9-6). * drivers/usbdev/usbdev_strings.c: Extended decoding and stringifying of USB trace output to include trace output from class drivers. (2013-9-6). * drivers/usbdev/usbmsc_desc.c: Fix a warning when USB MSC is compiled for a high-speed device (2013-9-7). * drivers/usbhost/usbhost_storage.c: If device is returning fatal transfer errors while attempt to initialize, don't bother with the startup retries; abort immediately so that the device will be reset and we can try again (2013-9-9). * drivers/usbhost/usbhost_storage.c: Correct a reference counting error: When an MSC device transfer fails while waiting for UnitTestReady (see 2013-9-9), the reference count was not being decremented. The end result is a memory leak (2013-9-10). * arch/arm/src/sama5/chip/sam_twi.h: Added SAMA5 TWI register definition file (2013-9-11). * arch/arm/src/sama5/sam_twi.c and .h: Framework for a SAMA5 TWI driver (not much present in initial checkin) (2013-9-11). * fs/nxffs: Clean up some compilation warnings (2013-9-12) * drivers/mtd/at24xx.c: Add support for the AT 24C512 part (2013-9-12). * arch/arm/src/sama5/sama5_twi.c: Clean up some errors that only occur with CONFIG_DEBUG_I2C (2013-9-12). * arch/arm/src/sama5/chip/sam_emac.h and sam_gmac.h: Register definition files for the SAMA5 EMAC and GMAC peripherals (incomplete on the initial commit) (2013-9-12). * arch/arm/src/stm32/stm32_can.c: Make filter register accessible for CAN1 and CAN2. Patch provided by Lorenz Meier (2013-9-13). * nuttx/include/nuttx/usb/cdcacm.h: Fix backward conditional compilation in the CDC/ACM driver with regard to remote wakeup and self-powered capabilites. Provided by Lorenz Meier (2013-9-13) * fs/romfs/fs_romfsutil.c: Fix for filenames > 15 characters. Provided by Lorenz Meier (2013-9-13). * arch/arm/src/stm32/Kconfig: Fix STM32 UART7/8 kconfig names and UART DMA. Provided by Lorenz Meier (2013-9-13). * configs/maple: Board configuration for the LeafLabs Maple and Maple Mini boards. From Librae (2013-9-13). * arch/arm/src/sama5/sam_emac.c and .h: Skeleton files for a SAMA5 EMAC driver. Not much in the initial files; these are just hacked out and gutted versions of the corresponding STM32 files (2013-9-13). 6.31 2013-10-28 Gregory Nutt * nuttx/fs/romfs/fs_romfsutil.c: Back out part of a recent ROMFS change (2013-9-14). * configs/sama5d3x-ek/src/sam_ethernet.c: Add support for PHY interrupts (2013-9-15). * arch/arm/src/kl/chip/kl_pit.h and kp_tpm.h: Add register definitions for the Freescale Kinetis KL25Z from Alan Carvalho de Assis (2013-9-15). * configs/ and a few Ethernet drivers: Add the prefix ETH0 to all PHY configuration selections. This will allow us to support to Ethernet MAC drivers with two different PHYs (identified with ETH0 and ETH1) (2013-9-17). * net/Kconfig and drivers/net/Kconfig: Move PHY selections from net/Kconfig to drivers/net/Kconfig where they belong. Add the previx ETH0_ to each PHY selection. And a new configuration CONFIG_NETDEV_MULTINIC that can be set to enable support for multiple Ethernet MAC drivers (not fully implemented yet). When Enabled, another set of PHY selections are enabled for ETH1_ (2013-9-17). * include/nuttx/net/mii.h: Add definitions for the Micrel KSZ8051 PHY (2013-9-17). * configs/zkit-arm-1768: MMC/SD is on SPI, not SSP0. From Rashid Fatah (2013-9-17). * configs/: Lots of defconfig files changes. A consequence of the above renaming and moving of the PHY configuration settings is that the you now also have to set CONFIG_NETDEVICES=y if you need to set a PHY configuration (2013-9-17). * arch/arm/src/lpc17xx/lpc17_spi.c: Remove undefined spi_select() prototype. This was causing compile time warnings (2013-9-17). * configs/sama5d3x-ek/src/sam_ostest.c: Add OS test support for the FPU test (2013-9-18). * arch/arm/src/sama5/sam_usbhost.h and include/nuttx/usb/usbhost_trace.h Correct some inconsistencies in the way that USB configuration settings are used. This caused compilation errors in SAMA5 OHCI when USB debug was ON but USB host tracing was off (2013-9-19). * nuttx/arch/arm/src/sama5/sam_clockconfig.c: When 480MHz UPLL is used to drive OHCI, it should have a divider of 10. However, that does not work. A divider of 5 does. Why? (2013-9-19). * Several USB device driver files: Change naming of SELFPOWERED and REMOTEWAKEUP to avoid name collisions. Prepend the name of the driver (for example CDCACM_SELFPOWERED) (201309-20). * configs/sama5d3x-ek/nsh and demo: Increase the number of pre-allocated watchdog timers. The default number of 4 was easily being exhausted in the more complex configurations. Enable the task name feature to provide prettier ps command output. src/sam_usb.c: Use more descriptive task names when starting the EHCI and OHCI monitor tasks (2013-9-20). * arch/arm/src/sama5/sam_ohci.c: Fix a place where DMA-related data needed to be flushed to data cache; Fix another where a virtual address was being used in a register where a physical address was required (2013-9-20). * arch/arm/src/armv7-a/cp15_clean_dcache.S and cp15_flush_dcache.S: fix an error in the alignment of addresses to cache line boundaries (2013-9-21). * drivers/usbdev/cdcacm_desc.c: Change the interval for the interrupt endpoint from 0xff (invalid) to 10. This is not a critical change but will avoid a complaint from the Linux driver when it overrides the 0xff value (2013-9-22). * configs/zkit-arm-1769: LED1 is now user controllable after booting. From Rashid Fatah (2013-9-23). * arch/arm/src/sama5/sam_hsmci.c: TX DMA disabled. It is just not reliable. No idea why. RX DMA is still used (2013-9-23). * driver/net/encx24j600.c: UDP/RXAVAIL backlog support from Max Holtzberg (2013-9-24). * Standardized stack checking logic so the interfaces can be used by common stack monitoring logic (2013-9-24). * drivers/net/Kconfig: Move CONFIG_NET_DUMPPACKET out of LPC17 and STM32 Kconfigs into the common network driver Kconfig (2013-9-25). * arch/arm/src/sam_emac.c: EMAC driver is basically functional. More testing is needed (as always) (2013-9-25). * configs: Changes to many defconfig files resulting from moving apps/examples/usbmsc to apps/system/usbmsc (2013-9-25). * configs: Changes to many defconfig files resulting from moving apps/examples/cdcacm to apps/system/cdcacm (2013-9-25). * configs: Changes to many defconfig files resulting from moving apps/examples/composite to apps/system/composite (2013-9-25). * configs/stm3210e-eval/composite: Converted to use the kconfig- frontends tool (2013-9-25). * arch/arm/src/sama5/sam_gmac.c: Initial GMAC driver is really just the EMAC driver forced to compile with the GMAC register definitions (2013-9-26). * arch/arm/src/sama5/sam_gmac.c and include/nuttx/net/gmii.h: Beginning of support for GMII/RGMII PHY support (2013-9-26) * net/netdev_txnotify.c: Look up of device using subnet will fail if the packet is being sent out of our subnet (via a router). The fallback here is just to use "eth0" if the subnet lookup fails. This will, of course, will have to be revisited if/when multiple NICs are supported. From Max Holtzberg (2013-9-27). * net/send.c: Fix some backward conditional logic in check to see if we should check if the ARP address in the table. From Max Holtzberg (2013-9-27). * drivers/net/encx24j600.c: Removed logic that polls for the next outgoing packet from the TX done interrupt handling. From Max Holtzberg (2013-9-27) * sched/os_start.c: Should not call group_setupidlefiles() if there are no file descriptors (and, hence, no file system) (2013-9-27). * arch/arm/src/sama5/sam_gmac.c: GMAC driver and GMII logic is code complete and ready for test (2013-9-27) * configs/compal_e86: Basic board support for the Motorola C139 (Compal E86) phone. From Craig Comstock (2013-9-27). * configs/compal_e86: Converted to use the kconfig-frontends tools (2013-9-27). * drivers/net/encx24j500.c: Use separate pools for RX and TX descriptors. From Max Holtzberg (2013-9-28). * nuttx/fs/fs_sendfile.c, nuttx/net/net_sendfile.c, and other file: Integrate an optimized sendfile() operation from Max Holtzberg (2013-9-28). * tools/mkdeps.*, nuttx/mm/Makefile, nuttx/libc/Makefile: Dependency generation generation was broken for directories that keep objects in a sub-directory. Fixed by adding a object path to the mkdeps.c, mkdeps.bat, mkdeps.sh tools (2013-0-29). * arch/arm/src/sama5/chip/sam_adc.h: ADC register definition file. Incomplete on initial check-in (2013-9-29). * arch/arm/src/sama5/sam_adc.c and .h: Framework for an ADC driver to come (just empty "skeleton" files on initial commit) (2013-9-30). * arch/arm/src/sama5/sam_touchscreen.h and .h: Framework for a touchscreen driver (also an empty "skeleton" file on the initial commit) (2013-9-30). * arch/arm/src/kl/kl_lowgetc.c and .h: First cut at low-level getc() function for operation with no file system (and, hence, no serial driver) (from Alan Carvalho de Assis, 2013-9-30). * configs/freedom-kl25z/minnsh: A new configuration that is an experiement to see how small we can get the NuttX footprint. From Alan Carvalho de Assis. (2013-9-30). * net/net_sendfile: The high performance sendfile logic is now functional. From Max Holtzberg (2013-9-30). * tools/define.sh: 'cut' no longer works as it once did. Script adapted to observed behavior (2013-9-30). * include/nuttx/net/route.h and net/net_*route.c: Partial implementation of a routing table. Not yet hooked into the build system (2013-10-1) * include/net/route.h: Defines the application interface to the routing table (2013-10-2). * configs/spark: Add configuration for the Spark Core. The initial check-in is basically the Maple Mini board (2013-10-2). * include/net/route.h and libc/net/lib_addroute.c and delroute.c: Add an application interface to manage the routing table (2013-10-2). * arch/arm/src/sama5/sam_adc.c and sam_tsc.c: The SAMA5 touschscreen drive is basically functional) (2013-10-3) * arch/arm/src/sama5/chip/sam_lcdc.h: Add SAMA5 LCD register definition header file (2013-10-4). * net/netdev_findbyaddr.c: Now (1) uses the routing table if available to look up the router to get to a remote network, and (2) if there is only a single network device and no route, then it will simply return that single device. The ARP logic will use the default router address associated with the interface in this case (2013-10-5). * net/netdev_router.c and net/uip/uip-arp.c: When the target IP address does not lie on the device's networker when we have a routing table, looking the correct router IP address to use in the ARP request. In that case, we want the MAC address of the router, not of the target endpoint (2013-10-5). * net/netdev_rxnotify.c and others: Use the new signature of rxnotify caused by the routing table. From Max Holtzberg (2013-10-6). * arch/arm/src/sama5/sam_lcdc.c and .h: Empty "skeleton" file that will eventually become an LCDC driver for the SAMA5 (2013-10-6). * net/net_close.c, net/uip/uip_tcpcon, and include/nuttx/net/uip/uip-tcp.h: Make net_close() nonblocking and free unestablished connections if no free connections available. From Max Holtzberg (2013-10-6). * net/net_close.c and other: Update of change of 2013-10-6 from Max Holtzberg (2013-10-8). * arch/arm/src/sama5/sam_lcd.c: LCDC driver is code complete and incorporated into the build system (but still untested (2013-10-8). * configs/sama5d3x-ek/nx: Add an examples/nx configuration that will be used for the SAMA5 LCD bring-up (2013-10-8). * configs/arduino-due/Kconfig and include/board.h: Add configuration to select revision 3 of the Arduino Due which has some small but important differences. Suggested by gdi@embedders.org. * arch/arm/src/sama5/sam_allocateheap.c, Kconfig, chip/sama5d3_memorymap.h: Add support so that subsets of the total DRAM (and other external memory) can be added to the heap, leaving other memory reserved for other purposes (like LCDC framebuffers) (2013-10-10). * arch/arm/src/sama5/sam_lcd.c: Change how DMA descriptors are allocated. My reading of the SAMA5 MATRIX is that the LCDC will be unable to DMA from internal SRAM (2012-10-10). * arch/arm/src/sama5/Kconfig and configs/sama5d3x-ek/nx/defconfig: The default LCD resolution is now RGB565. Added output resolution selection which can be different from the software resolution (2013-10-10. * arch/arm/src/sama5/sam_lcd.c wait before modifying register if the LCDC is re-synchronizing (SIF).

From Max Holtzberg (2013-10-11). * drivers/net/encx24j600.c and Kconfig: ENCX24J600: Improved descriptor handling, free packets on rx abort interrupt. From Max Holtzberg (2013-10-11). * arch/arm/src/sama4/sam_lcd.c and configs/sama5d3x-ek/include/board.h: Fix PWM precealler divider. This eliminiates the backlight flicker (2013-10-11). * arch/arm/src/sama5/sam_boot.c: Correct how framebuffer memory was being mapped.

From Max Holtzberg (2013-10-17). * net/net_sendfile.c: Correct parameter passed to netdev_txnotify() from Max Holtzberg (2013-10-17). * include/nuttx/net/uip/uip-tcp.h, net/send.c, uip/uip_tcpconn.c, and uip/uip_tcpinput.c: Change how the initial minimum MSS is calculated. Max Holtzberg (2013-10-17). * net/uip/uip_tcpinput.c: Move tcp connection into SYN_RCVD state after aception instead of bypassing and moving directly into ESTABLISHED. From Max Holtzberg (2013-10-17). * net/net_sendfile.c: Let the ACK callback handle the REXMIT flag and don't return until all data has been ACK'd. From Max Holtzberg (2013-10-17). * arch/arm/src/stm32/chip/stm32f40xxx_dma.h: Typo fixes for UART7 and UART8 DMA configs. From Mike Smith (2013-10-18). * arch/arm/src/stm32/Kconfig: DMA priority corrections from Mike Smith (2013-10-18). * arch/arm/src/stm32/stm32*_dma.c, stm32_sdio.c, and stm32_dma.h: Changes to the stm32_dmacapable API. In order to correctly verify that a buffer can be transferred, the transfer count and the CCR value are required. Implemented stm32_dmacapable for stm32f1xx devices. Enhanced stm32_dmacapable for stm32f2xx and stm32f4xx devices to check for additional conditions that will cause DMA to fail or lose data (2013-10-18). * include/nuttx/sdio.h: Add a preflight method to the SDIO interface. From Mike Smith (2013-10-18). * drivers/mmcsd/mmscd_sdio.c: Enhanced the mmcdd_sdio driver to perform DMA preflight operations and fail DMA read/write requests that fail preflighting. From Mike Smith (2013-10-18). * fs/fat/fs_fat32.c: Enhanced the FAT32 filesystem code to understand DMA preflight failures, and to use the file sector buffer as a bounce buffer when a user-supplied buffer is not suitable for DMA.

From Ken Pettit (2013-10-31). * arch/arm/src/stm32/stm32_usbdev.c: On a failure to bind the class driver, the driver reference was being nullified too soon. This caused an exception in usbdev_reset() later. The driver reference will be nullified later usbdev_unregister when the caller gets the error. From David Sidrane (2013-10-31). * drivers/mtd/mtd_config.c and include/nuttx/configdata.h: Add a container for an MTD device that can be used to provide a simple, lightweight interface to configuration data storage that resides on some storage media that is wrapped as an MTD device.

From David Sidrane (2011-10-1). * drivers/usbdev/usbmsc.c and usbmsc_scsi.c: pthread_join() does not work if called from a different task group than the pthread. This is correct behavior, but a problem. The correct solution would be configure the USB MSC thread to a task, however, this workaround from David Sidrane plugs the hole for now (2013-11-1). * drivers/mtd/mtd_config.c: Reduce configuration header size. From Ken Pettit (2013-11-1). * drivers/mtd/sst25.c: Improved write performance by fixing a bug that prevented operation in the faster write mode. The code did not wait on the last write complete before issuing the WRDI The loop in general failed to wait on the fist 2 bytes after the SST25_AAI if the next 2 were FF FF, then it would reissue the address but not cancel the write. Reorganized to always wait for completion after and address with data write and on any data write so that the device is complete before WRDI is sent.

Also add support for decoded USB trace strings. From David Sidrane (2013-11-5). * drivers/usbdev/cdcacm.c, composite.c, usbmsc.c: uninitialization logic cause re-use of a stale pointer. Changed to a two pass uninitialization for the case of the composite driver: Memory resources are not freed until the second uninitialization pass. From David Sidrane (2011-11-5). * arch/arm/src/sama5/sam_pwm.c and .h: Add PWM driver for SAMA5 untested on initial checkout (not even incorporated in to build system) (2013-11-6). * arch/arm/src/sama5/Make.defs and Kconfig: SAMA5 PWM driver now incorporated into build and configuration system. Builds with no errors (2013-11-6). * configs/sama5d3x-ek: Add support for the PWM test for the SAMA5D3x-EK board (2013-11-6). * arch/arm/src/sama5/sam_pwm.c and .h: SAMA5 PWM driver is now functional (2013-11-7). * include/nuttx/audio/i2s.h: First cut at an I2S interface definition.

From David Sidran (2013-11-7). * arch/arm/src/sama5/sam_ssc.c and .h: First cut of SAMA5 SSC/I2S driver is code complete (2013-11-9). * arch/arm/src/stm32 (numerous files): OTG FS device and host drivers extended so that they can support either the OTG FS peripheral or the OTG HS peripheral (in FS mode). This was done as a quick way to get USB support on the STM32F429 which has only OTG HS. From Ken Pettit (2013-11-10). * configs/stm32f429i-disco: Add support for the usbnsh and usbmsc configurations using the OTG HS peripheral in FS mode.

From Ken Pettit (2013-11-10). * libc/audio/lib_buffer.c: Moved audio/buffer/c to libc/audio/lib_buffer.c. This file was moved because it contains buffer management functions that must be available to audio applications. If it was left in the audio/ directory then it would not be available to applications in the NuttX Kernel build (2013-11-10). * arch/arm/src/sama5/sam_ssc.c and Kconfig: Add configurable support for SSC loopback mode (2013-11-10). * include/nuttx/audio/i2s.h, arch/arm/src/sama5/sam_ssc.c, and drivers/audio/i2schar.c: Improved I2S interface design: Simplified audio buffer queuing (2013-11-10). * arch/arm/src/sam34 and arch/arm/include/sam34: Basic support for the Atmel SAM4E family.

From Ken Pettit (2013-11-28). * fs/fs_inode.c: The inode semaphore must be re-entrant. Here is the re-entering path that I found: (1) USB host connects to FLASH drive and creates /dev/sda, (2) /dev/sda is mounted, (3) FLASH drive is removed but /dev/sda is not destroyed because there is still a reference on the device because of the mount, (4) umount() is called, taking the inode semaphore, now the driver tries to destroy the block driver by calling unregister_blockdriver(). But (5) unregister_blockdriver() also takes the inode semaphore causing a deadlock if the inode semaphore is not re-entrant. (2013-11-28). * configs/viewtool-stm32f107: Add board support for the ViewTool STM32F103/F107 board with the STM32F107VCT6 installed. Initial check-in is the unverified board-support framework only (2013-11-30). * configs/viewtool-stm32f107/src/stm32_buttons.c and stm32_leds.c: Add support for LEDs an buttons on the ViewTools STM32F107 board (2013-11-30). * fs/nxffs/nxffs_initialize.c: First of probably several changes for NAND FLASH. NAND can report read errors because of bad ECC. Logic in NXFFS must account for it and not just throw in the towel every time a read fails (2013-11-30). * drivers/mtd/mtd_nand* and arch/arm/src/sama5/sam_nand.c: NAND accesses now work (at least with software ECC and now DMA). Still lots of testing to be done (2013-11-30). * fs/nxffs/nxffs_dump.c: Do not abort on a read error. Just not the error and continue. Otherwise, we would not be able to dump NAND FLASH (2013-11-30). * fs/nxffs: All read error logic has been revisited and modified in most places. If we are using NAND, then read errors probably mean that the block that was read contains uncorrectable bit errors. In this case, we cannot just give up and abort the operations. Rather, we need to treat read error like normal bad blocks in order to work with NAND (2013-12-2). * fs/nxffs/Kconfig and nxffs_initialize.c: Make the start up scan of the media option. It just takes to long! (2013-12-02). * drivers/mtd/mtd_nand.c: Fix a typo in calculation of page number (2013-12-02). * drivers/mtd/README.txt: New README file (2013-12-04). * arch/arm/src/lm/lm_start.c: Don't initialize .data if not running from FLASH (2013-12-05). * fs/fat/fs_configfat.c: Fix a typo in the FAT16 formatting logic. Was this ever able to format a FAT16 volume? (2013-12-05). * drivers/mtd/mtd_nand.c: Check if block number is within range at the top of the loop not the bottom. Otherwise, we will do a bogus transfer with the out-of-range block before we test it (2013-12-05). 6.33 2014-01-30 Gregory Nutt * arch/arm/include/a1x and src/a1x: Directory structure to support the Allwinner A10. Not much there on the initial check-in (2013-12-7). * configs/pcduino-a10: Directory structure for the pcDuino board. This board is based on the Allwinner A10 (2013-12-7). * arch/arm/src/a1x/a1x_boot.c and chip/a1x_intc.h: More A10 logic (2013-12-8). * arch/arm/src/a1x/a1x_irq.c: A10 interrupt handling logic (partial) (2013-12-8). * drivers/video/ov2640.c: An OV2640 camera driver that will be used to verify the SAMA5D3x-EK ISI peripheral (2013-1209). * sama5d3x-ek/ov2640 and src/sam_ov2640.c. Board logic to test the SAMA5D3 ISI peripheral usign the OV2640 camera (2013-12-9). * arch/arm/src/a1x/chip/a1x_uart.h: A10 UART register definition header file (2013-12-9). * include/nuttx/video/fb.h: Move fb.h to include/nuttx/video/ (2013-12-10). * include/nuttx/video/rgbcolors.h: Move rgbcolors.h to include/nuttx/video. (2013-12-10). * include/nuttx/fs/smart.h: Move smart.h to include/fs/smart.h (2013-12-10). * include/nuttx/fs/ramdisk.h: Move ramdisk.h to include/fs/ramdisk.h (2013-12-10). * arch/arm/src/a1x/chip/a1x_pio.h and a10_piocfg.h: PIO register definition header files (2013-12-10). * arch/arm/src/a1x/a1x_pio.c and .h: Support for PIO configuration (2013-12-11). * libc/misc/lib_match.c: Pattern matching logic extended to handle matches to sets of characters and ranges of character values. From Ken Pettit (2013-12-12). * fs/procfs, drivers/mtd, fs/smartfs, includes/nuttx/fs, .. to many files to list: Extensive changes by Ken Pettit to extend procfs/ functionality. Includes some incomplete changes related to SmartFS (2013-12-12). * configs/stm32f429i-disco: Add support for procfs/ MTD part names. From Ken Pettit (2013-12-12) * arch/arm/src/a1x/chip/a1x_timer.h: Timer register bit definitions (incomplete on initial check-in) (2013-12-12). * lbc/time/lib_strftime.c: Need null-termination on the string generated by strftime(). From Max Holtzberg (2013-12-12). * sched/nanosleep.c and include/time.h: Add nanosleep() (2013-12-12). * libc/unistd/lib_sleep.c and lib_usleep.c. Move sleep() and usleep() from sched/sleep.c and usleep.c to libc/unistd. These functions now just call nanosleep(). (2013-12-13). * syscall/ and include/sys/syscall.h: Remove sleep and usleep system calls. Add nanosleep system call (2013-12-13). * arch/arm/src/a1x/a1x_timerisr.c: Timer interrupt handler for the A10 (2013-12-13). * arch/arm/src/a1x/a1x_config.h: Header file to keep track of A10 configuration decisions (2013-12-13). * arch/arm/src/a1x/a1x_lowputc.c, a1x_serial.c, and a1x_serila.h: Beginning of an A10 serial driver. From Alan Carvalho de Assis (2013-12-13). * fs/procfs/procfs_utils.c: Move some re-usable functions out of fs_procfsproc.c into a utility file (2013-12-14). * fs/procfs/fs_procfsuptime.c: Supports /proc/uptime (2013-12-14). * graphics/nxconsole/nxcon_font.c: Fix a typo that causes a compile error when CONFIG_NXCONSOLE_BPP < 8. From Librae (2013-12-15). * fs/procfs/fs_procfsproc.c: procfs now shows information about the group that each thread belongs: Like parents, group member, open file, and open sockets (2013-12-15). * fs/procfs/fs_procfsproc.c: Now shows task stack information (2013-12-15). * arch/arm/src/armv7-a/cp15.h: Review A9 TRM and updated CP15 register definitions accordinglyg (2013-12-16). * Makefile.unix: Now has supports qconfig and gconfig targets. These tools will use the Qt and GTK versions of the kconfig- frontends configuration tools (if you built them) (2013-12-16) * arch/arm/src/armv7-a/arm_head.h: Fix some errors in the cache invalidation logic (only seem to matter for Cortex-A8) (21-3-12-19). * Kconfig and all Make.defs files: Add CONFIG_DEBUG_NOOPT. Now you can independently enable/disable debug symbols and optimization (2013-12-20). * configs/README.txt and Documentation/NuttxPortingGuide.html: Remove documentation of NuttX configuration variables. Since converting to the kconfig-frontend tools, the NuttX configuration is now documented in the Kconfig files and summarized in the autogenerated Documentation/NuttXConfigVariables.html file. This old configuration variable documentation is now a liability and, hence, was removed (2013-12-20). * arch/Kconfig, arch/arm/Kconfig, arch/arm/include/x/chip.h, and and arch/arm/src/x/x_irq.c where x={kinetis, lm, lpc17xx, lpc43xx, sam34, or stm32}: Beginning of support for nested, high priority interrupts. Lots more still needs to be done (2013-12-21). * arch/arm/src/armv7-m/up_exception.S and arch/arm/src/x/x_vectors.S: where x={kinetis, lm, lpc17xx, lpc43xx, sam34, or stm32}: completes the basic implementation of nested, high priority interreupts. Still untested and need documentation (2013-12-21). * configs/stm3210e-eval/buttons: Converted to use kconfig-frontends tools (untested) (2013-12-22). * configs/Kconfig, configs/viewtool-stm32f107/include/board-stm32f103vct6.h, and /board-stm32f107vct6.h: The viewtool board can now be configured to support either the STM32F103VCT6 or the STM32F107VCT6 (2013-12-22). * configs/Kconfig, README.txt, viewtool-stm32f107/highpri, Kconfig, README.txt, and src/stm32_highpri.c: This is the initial framework for a test of the high priority, nested interrupt logic. Still incomplete and does not yet run (2013-12-22). * arch/arm/src/armv7-m/ram_vectors.h and up_ramvec_initialize.c: Correct alignment of the RAM vector table (2013-12-22). * Kconfig: Support configuration of interrupt controller debug output (2013-12-22). * configs/viewtool-stm32f107/scripts: Need to do some special things in linking of the common vectors are used (2013-12-22). * arch/arm/include/*/irq*.h: Add definition NR_VECTORS so that the RAM vector logic can know how many vectors there are. NR_IRQS is often not equal to NR_VECTORS (2013-12-23). * arch/arm/src/*_vectors.S: Standardize the name of the vector table and the name of the common vector handling logic so that the MCU- independent logic and work with these (2013-12-23). * configs/viewtool-stm32f107/scripts: Move the RAM vector tables to the beginning of SRAM. It seems to require this alignment. Also, we don't need different scripts for the CMNVECTOR case now that the vector table has a common name. * arch/arm/src: armv-7/up_exception.S and xxx/xxx_vectors.S where xxx={kinetis, lm, lpc17xx, sam34, and stm32}: Modified register usage when saving the context on the stack: In order to handler nested interrupts, the stack pointer must be used so that when it is decremented, the contents on the stack are protected from the nested interrupt handling (2013-12-23). * arch/Kconfig: The CONFIG_ARCH_INT_DISABLEALL feature is disabled (i.e., depends on EXPERIMENTAL). That is because the current implementation will not work because interrupts get disabled in the interrupt handler too, defeating the nesting of interrupts. The fix is easy: It just needs more levels of priority of disabling interrupts vs interrupt handling (2013-12-23). * configs/viewtool-stm32f107/src/stm32_highpri.c: Improved debug output (2013-12-23). * drivers/lcd/memlcd.c and include/nuttx/lcd/memlcd.h: Support for the Sharp Memory LCD from Librae (2013-12-23). * configs/maple/nx and src/: Add support for a custom Sharp Memory LCD on the Maple board. From Librae (2013-12-23). * configs/viewtool-stm32f107/netnsh: Add a NSH configuration that supports networking with the DP83848C module installed (2013-12-25). * configs/viewtool-stm32f107/src/stm32_nsh.c, stm32_mmcsd.c, stm32_usb.c, and stm32_usbmsc.c: Lay out basic framework for USB and SD card support. Code is incomplete and has been neither built nor tested (2013-12-25). * nuttx/arch/arm/src/stm32/Kconfig, chip/stm32f103vc_pinmap.h, stm32f105vb_pinmap.h, and stm32f107vc_pinmap.h: Fix configuration and pin definition that would prevent building USB for the connectivity and performance lines (2013-12-25). * stm32l15xxx_pinmap.h: Fix a typo in USB pin definitions (2013-12-25). * configs/viewtool-stm32f107: Fix building of USB for F103 and F107. F103 has device only; F107 has OTG FS (2013-12-25). * arch/arm/src/stm32/stm32f10xxx_rcc.c and chip/stm32f10xxx_rcc.h: Add clocking support for STM32F107 USB OTG FS (which does not work) (2013-12-26). * configs/viewtool-stm32f107: Updates to USB for F103 and USB OTG FS for F107 (2013-12-16). * arch/arm/src/stm32/chip/stm32f3xxxx_pinmap.h: Fix pin definition names for SPI2 MOSI and MISO. Noted by Brian Webb (2013-12-27). * graphics/nxmu, nxsu, and nxglib and libc/nx, nxmu, and nxglib: Massive reshuffling of files with (hopefully) no logic changes. This reshuffling is necessary if we ever want to build graphics applications as kernel builds. There is still more today (NXTK and NXFONTS need to be moved to libc as well) (2013-12-27). * Move libc/nx, nxmu, and nxglib to a new library, libnx. The NX graphics is not properly a part of libc (2013-12-28). * Move graphics/nxfonts to libnx/nxfonts (2013-12-28). * Move graphics/nxtk to libnx/nxtk (2013-12-28). * syscalls: Need to add sem_timedwait() (2013-12-28) * Move more files from graphics/nxmu to libnx/nxmu (2013-12-29). * graphics/nxmu/nx_start.c: NX server start-up wrapper function to simplify starting the NX server from within the RTOS (2013-12-29). * configs/stm3240g-eval/kernel and configs/stm3240g-eval/scripts: Port kernel build logic from the STM32F4Discovery to the STM3240G-EVAL. This will eventually support testing of the kernel mode NX server (2013-12-29). * configs/stm3240g-eval/nxwm: Converted to use the kconfig-frontend tools (2013-12-29). * configs/stm3240g-eval/knxwm: Add a kernel mode NxWM build configuration (not yet verified) (2013-12-29). * Moved configs/stm3240g-eval/src/up_cxxinitialize.c to apps/platform/stm3240g-eval/up_cxxinitialize.c: Now it is available in user-space in the kernel mode build (2013-12-29). * graphics/nxbe, nxsu, libnx/nxmu, and nxtk: Need to be consistent with which allocator is used in the different configurations. Always uses the user-space allocator because that one is required in certain configurations (2013-12-30). * include/nuttx/kthread.h: Move kernel thread definitions out of os_internal.h so that the rest of the OS can start kernel threads as well (2013-12-30). * configs/sim/mount/defconfig: Converted to use kconfig-frontends tools (2013-21-31). * configs/z16f2800100zcog/nsh: Add a Z16F NSH configuration. Does not yet work (2014-1-1). * arch/arm/src/stm32/stm32_serial.c: Single-wire UART support from Thomas Grubler (2014-1-2). * tools/configure.c and mkdeps.c: Fixes for Windows build issues from Max Holtzberg (2014-1-4). * configs/olimex-stm32-p107/nsh/Make.defs: Add native Windows build support for the Olimex STM32 P107. From Max Holtzberg (2014-1-4). * Makefile.win: Changes for native Windows build: Fix creation of a .version file if one does not exist. Make sure that the APPDIR environment variable is set before configuring. From Max Holtzberg (2014-1-4). * configs/viewtool-stm32f107/src/stm32_ssd1289.c: Add support for Viewtool SSD1289-based LCD (untested on initial checkin) (2013-1-5). * arch/arm/include/syscall.h and armv7-a/syscall.h: Add the syscall.h header file needed for the Cortex-A architecture (2014-1-5). * arch/arm/src/a1x/a1x_serial.c: Remove bad flow control logic. Add missing interrupt handling logic for UART4-7 (2014-1-6). * nuttx/tools/mkconfig.c: Cast size to unsigned in calculation of CONFIG_RAM_END to avoid complains about integer overflow (2013-1-6). * nuttx/tools/mkconfig.c: Back out the last change, this causes problems for assembly language. How to prevent the integer over- flow warnings? (2014-1-6). * arch/arm/src/a1x/a1x_serial.c: Handle BUSY interrupt (2014-1-6). * arch/arm/src/armv7-a/arm_head.S and arm_pghead.S: Add more nop's after enabling the MMU. The cortex-a8 seems to need these (2014-1-7). * arch/arm/src/a1x/a1x_serial.c: Correct handling of the BUSY interrupt (2014-1-7). * include/sys/types.h: Add a bogus rsize_t type (2014-1-7). * libc/stdio/lib_gets_s.c: Add a quick'n'dirty implementation of gets_s() which replaces gets() in C11 (2014-1-7). * libc/stdio/lib_fopen.c: Add support for new C11 exclusive open ("x") (2014-1-7) * include/threads.h: First crude cut at a C11 threads.h header file (just maps to pthreads) (2014-1-7). * libc/stdio/lib_libfgets.c: Common implementation supports all of the slightly different requirements of gets(), gets_s(), and fgets() (2014-1-7). * arch/arm/include/stm32/chip.h and chip/stm32f103ze_pinmap.h: various fixes for STM32F103ZE SPI3. From Steve Redler IV (2014-1-7). * graphics/nxsu/Make.defs: Typo that crept into build in recent NX reorganization. Found by Steve Redler IV (2014-1-7). * graphics/nxsu/: Another typo from the recent NX reorganization from Steve Redler IV (2014-1-7). * graphics/nxbe/nxbe_closewindow.c, nx_close.c, nx_constructwindow.c, nx_open.c, and nx_openwindow.c: Needs to use kuzalloc and kufree, not umm_zalloc and umm_free. Additional typo in nx_constructwindow.c (wnd should be hwnd). Also noted by Steve Redler IV (2014-1-7). * configs/viewtool-stm32f107/src/stm32_touchscreen.c (and other files): Add support for the XPT2046 touchscreen controller on the Viewtool LCD module connected to the Viewtool STM32F103 board (2014-1-9). * libc/strings/lib_stpcpy.c: Add stpcpy() (2014-1-9). * arch/arm/src/a1x/a1x_lowputc.c and a1x_serial.c: Mystery finally solved: The A10 serial clock is the OSC24M clock. Thanks to Alan Carvalho de Assis (2014-1-10) * binfmt/binfmt_loadmodule.c: Fix a memory leak (2013-1-11). * configs/stm3vldiscovery: Support for the STM32VL-Discovery board. Contributed by Alan Carvalho de Assis (2014-1-12). * net/net_close.c, net/Kconfig, include/nuttx/net/net.h, and include/sys/socket.h: Add support for the SO_LINGER socket option. Extended from logic provided by Jason Jiang. Enabled with CONFIG_NET_SOLINGER. At this point, it has only been verified that the changes does not seem to do any harm (2014-1-13). * net/connect.c and net/uip/uip_callback.c: prevent tcp_connect callback from being double freed. From Max Holtzberg (2014-1-13). * net/Kconfig and include/nuttx/net/uip/uipopt.h: Add configuration support for forthcoming TCP write buffering (2014-1-13). * net/net_send_buffered.c, net_send_unbuffered.c, and uip/uip_tcpwrbuffer.c: First set of changes to bring in Jason Jiang's TCP write buffering logic. Still not complete but apparently harmless if not selected. (2014-1-13). * All of Jason Jiang's TCP write buffering logic is checked in. Unfortunately, it does not yet work (2013-1-14). * configs/px4fmu-v2_upstream: Configuration for testing simple configurations on the PX4FMU v2. This version is incomplete for the PX4 application and is not a replacement for the version in the PX4 GIT repository. * fs/fat/fs_fat32.c: A correction to FAT cluster allocation from Tridge via Lorenz Meier (2014-1-14). * net/net_clone.c: If CONFIG_NET_TCP_WRITE_BUFFERS is selected, then the socket-related write buffering information must copied with the other cloned socket data (2014-1-14). * net/net_close.c: If CONFIG_NET_TCP_WRITE_BUFFERS is selected, then it is necessary to free the write buffer callback structure when the socket is closed (2014-1-14). * fs/fat/fs_fat32.c: Fix some root directory logic that was conditionally done only for FAT 32. Apparently this needs to done for all FAT types. From Tridge via Lorenz Meier (2014-1-14). * arch/arm/src/armv6-m/up_doirq.c and armv7-m/up_doirq.c and all implementations of up_maskack_irq() for all Cortex-M architectures: Do not disable and enable the IRQ on each interrupt. Because (1) interrupts are already disabled on interrupt entry, (2) this interferes with controlling the IRQ interrupt setting from interrupt handlers, and (3) up_disable_irq() does not work anyway so that this has never done anything (2014-1-15). * All implementations of up_disable_irq() for all Cortex-M3 and M4 architectures: To enable an interrupt on the Cortex-M3/4 CPU, you need to set a bit in the ISER registet on the Cortex-M3/4 CPU, you need to set a bit in the ISER register. To disable the interrupt, you need to set a bit in the ICER register. Existing logic was trying to disable interrupts by clearing the bit in the ISER register. That will not work; writing a '0' to the ISER register has no effect. That means that up_disable_irq() was doing nothing! It turns out that that is not really important because up_disable_irq() is not really used for that purpose. But some spurious STM32 ADC interrupts have been reported to me and this turned out to be the cause in that case. My concern now that up_disable_irq() works is that there may now be unmasked bugs that leave devices in the disabled state? Thanks to Manuel Sthn for the tip(2014-1-15). * libc: Move strtol(), strtoll, strtoul(), strtoull(), and strtod() from libc/string to libc/stdlib where they belong (2014-1-16). * configs/Kconfig: Board configuration sub-directory can now be specified. The default need not be used. This is really only useful when CONFIG_ARCH_BOARD_CUSTOM is selected and there is no meaningful default sub-directory (2014-1-16). * configs/Kconfig: Backed out the previous change for two reasons: (1) it has a bad side effect in that the sub-directory setting no longer tracks the board setting, and (2) you still can't source the Kconfig file from the custom board directory (2014-1-16). * Makefile.unix, Makefile.win, and configs/Kconfig: After thinking a little harder, I re-implemented the backed-out custom configuration feature. The new version does not have bad side-effect (1) (but still has bad side-effect (2)) (2014-1-16). * arch/x86/Kconfig and configs/qemu-i486/nsh/Make.defs and ostest/Make.defs: Add a configuration option to select the -m32 compiler option when building for a 32-bit target on a native 64-bit compiler (2014-1-18). * include/ctype.h: Typo in macro name: iscntrl, not iscontrol (2104-1-17) * libc/unistd/lib_getopt.c: If there are no arguments (argc == 1), then getopt() will leave the optind variable in an undefined state (2014-1-20). * configs/olimex-stm32-p107: Fails to build if SPI3 for UEXT is not remapped. From Max Holtzberg (2014-1-21). * Several network related files: Changes from Max Holtzberg to improve how network status is reported. New controls to manage carrier detect. (2014-1-21). * configs/16z: Add basic support for the 16z board. The 16z board is based on the ZiLOG ZNEOZ16F2811AL20EG part. See https://github.com/toyaga/16z for further information (2014-1-22), * tools/Config.mk: 'cypath' must be called if we are using a Windows native toolchain with the Cygwin 'make' to convert paths to proper Windows paths. From Richard Cochran (2014-1-23). * /arch/arm/src/Makefile: dependency directory list is now computed from the VPATH. From Richard Cochran (2014-1-23). * arch/arm/src/efm32 and include/efm32: Basic support for the EFM3 processor family from Richard Cochran (2014-1-23). * configs/efm32-dk3650: This is Energy Micro's development kit for the Leopard Gecko MCU, which is an ARM Cortex-M3 device. From Richard Cochran (2014-1-23). * arch/arm/src/armv7-m/up_memcpy.S: Assembler changes with the gcc-47 distribution from ARM mean that we need to be explicit about branch sizes; one or more of the wide branch opcodes results in bad table branching. From Mike Smith (2014-1-23). * Many files: renamed up_buttoninit() to board_button_initialize to better conform to the naming standard. Now ONLY prototypes in include/nuttx/arch.h (2014-1024). * Rename up_buttons() to board_buttons() for the same reason (2014- 1-14). * Rename up_irqbutton() to board_button_irq() (2014-1-24). * Rename up_ledinit() to board_led_intialize() (2014-1-24). * Rename up_ledon() to board_led_on() and up_ledoff() to board_led_off() (2014-1-24). * arch/x86/src/qemu-i486/gemu_head.S: Patch from Matt Campbell to fix 'Error: .size expression for idle_stack does not evaluate to a constant" (2014-1-25). * arch/arm/include/efm32, arch/arm/src/efm32, and configs/efm32-dk360: Removed all EFM32 support. Not yet ready to be fielded (2014-1-27). * arch/arm/src/armv7-a/arm_head.S, sama5/sam_boot.c, and several other files: Now supports execution from NOR FLASH with .data and .bss in SDRAM. This was not possible prior to this because .bss and .data were initialized before SDRAM was configured. This logic is still kind buggy. (2014-1-28). * arch/arm/src/armv7-a/arm_head.S and arm_pghead.S: Back off to a somewhat less efficient loop for initializing .data and .bss. The original, efficient logic violated the ARM C ABI. It was okay when called from boot logic, but not when called from C logic. This fixes bugginess reported on 2014-1-28. (2014-1-29). 7.1 2014-03-15 Gregory Nutt * arch/arm/src/lm/lm_serial.c: Fix cut'n'paste error that prevented UARTS2-7 from being used with the LM4F120 Launchpad (2014-02-03). * configs/stm32f4discovery/src: Almost everything renamed to conform to the ever-evolving naming standard (2014-02-03). * arch/arm/src/a1x/a1x_serial.c: Had the same cut'n'paste error that the LM4f120 Launchpad had (2013-02-03). * Documentation/NuttXCCodingStandard.html: Add a coding standards document. Very boring stuff (2014-2-6). * Several changes to restore the native Windows build (2014-2-7). * arch/arm/src/lpc17xx/lpc17_usbhost.c: Fix an compilation error that crept into the LPC17xx USB host driver. What happened here? (2014-2-9). * drivers/usbhost/usbhost_hidmouse.c and other files: Add support for a HID boot mouse device. It compiles but is otherwise completely untested on initial check-in (2014-2-9). * configs/olimex-lpc1766stk/src/lpc17_hidmouse.c and hidmouse: Add support of a test of the USB HID mouse (2014-2-9). * drivers/usbhost/usbhost_hidmouse.c: The driver appears to be functional. But there are usability issues: How do you use the mouse with no cursor? The HID mouse currently emulates a touchscreen driver. That would work in the long run for several reasons (see the top-level TODO list for details) (2014-2-9). * include/nuttx/input/mouse.h and drivers/usbhost/usbhost_hidmouse.c: Defined a mouse interface that is very similar to a touchscreen interface, but allows reporting of all mouse buttons. Also, unlike touchscreen drivers, mouse drivers need to report positional data with no button is pressed so that the mouse position can drive a cursor (2014-2-10). * drivers/usbhost/usbhost_hidmouse.c, include/nuttx/input/mouse.h, and include/nuttx/usb/hid.h: Add support for a mouse wheel (2014-2-10). * drivers/lcd/mio283qt9a.c and include/nuttx/lcd/mio283qt9a.h: Support for the MIO283QT9A LCD. From Toby Duckworth (2014-2-10). * configs/mikroe-stm32f4/src/up_mio283qt9a.c: The Mikroe STM32F4 can now support the newer MIO283QT9A LCD. From Toby Duckworth (2014-2-10). * MANY files changes based on complaints from the tool CppCheck. Several latent bugs were fixed (and most likely some new typos were introduced) (2014-2-10). * arch/arm/include/samd and src/samd: Basic framework to support Atmel SAMD20 Cortex-M0+ chips. Initial check-in is incomplete; this is a work in progress (2014-2-12). * configs/samd20-xplained: Framework to support the Amtel SAMD20 Xplained Pro. Initial check is just an unverified, rough port of the SAM4L Xplained Pro configuration (2014-2-12). * arch/arm/src/stm32/stm32_serial.c: Fix cloned typo: FLOWCONTROL vs FLOWCONROL (2014-2-14). * net/uip/uip_tcptimer.c: Back out a small part of the 6.33 write buffering changed. David G says that this causes problems in connecting to a server (2014-2-15). * The basic SAMD20 Xplained Pro port is complete but still untested (2014-2-16). * sched/task_terminate.c: Always returns an error because the return value was not being set correctly. From Gosha (2014-2-18). * stm32f429i-disco/ostest-fpu: OS test for FPU-enabled system from David Alessio (2014-2-18). * Other misc changes to support FPU on STM32F429 Discovery from David Alessio (2014-2-18) * stm32f429i-disco/src: Files renamed to make more consistent with current board file naming conventions (2014-2-18). * stm32 SPI: Disable SPI before changing CR1 register. From David Sidrane (2014-2-18). * stm32 TIM: Set CCMR when selecting timer channel. From David Sidrane (2014-2-18). * configs/spark: Board configuration updated by David Sidrane (2014-2-19). * libc/stdio/lib_sscanf.c: Bug fixes from David Sidrane (2014-2-18). * nuttx/drivers/wireless/cc3000 and nuttx/include/nuttx/wireless/cc3000: Numerous updates to the CC3000 driver from David Sidrane (2014-2-18). * nuttx/configs/stm3240g-eval/webserver: Converted to use the kconfig-frontends tools by Alan Carvalho de Assis (2014-2-18). * configs/mbed: All mbed configurations have been converted to use the kconfig-frontends tools (unverified) (2014-2-18). * fs/fs_opendir.c, fs_readdir.c, et al: Modified so that errors will not be reported if you attempt to list a empty pseudo-directory (2014-2-19). * fs/fs_rmdir.c: 'rmdir' can now be used to remove empty directories in the pseudo-filesystem such as might be left after umounting a file system (2014-2-19). * fs/fs_mkdir.c: 'mkdir' can now be used to create empty directories in the pseudo-filesystem (2014-2-19). * drivers/lcd/mio283qt9a.c: Bug fix from Toby Duckwork (2014-2-19). * fs/fs_rename.c: 'rename' can now be used to rename nodes in the pseudo-filesystem (2014-2-19). * arch/arm/src/samd/sam_sercom.c: Move some common SERCOM logic from the USART-specific files to a share-able file where it can also be used by SPI and I2C drivers (2014-2-19). * arch/arm/src/samd/sam_spi.c: Add framework for a SAMD SPI driver. The initial check-in is a crude port of the SAMA5 SPI driver with a lot of missing logic (2014-2-19). * arch/arm/src/lm/lm_lowputc.c and lm_serial.c: Several errors are unmasked with UARTs > UART2 are enabled. From Gosha (2014-2-19). * arch/arm/src/samd/sam_spi.c: The SPI driver is code complete, but untested (2014-2-20). * configs/olimex-lpc1766stck/ftpc: Configuration convert to use the kconfig-frontends tools by Alan Carvalho de Assis (2014-2-20). * fs/fs_mkdir.c: 'unlink' can now be used to remove things from the pseudo-filesystem. A new configuration option as been added: CONFIG_DISABLE_PSEUDOFS_OPERATIONS that effectively can be set back out these recent changes in rmdir, mkdir, unlink, and rename for operations on the pseudo-filesystem (2014-2-20). * Kconfig: Add an option to select default values for configuration variables based upon whether you want a smaller footprint or more features. CONFIG_DEFAULT_SMALL is used in sched/Kconfig and fs/Kconfig and in apps/. It turns out this this is not very useful if you are modifying existing configurations because then the defaults do not apply (2014-2-20). * arch/arm/src/sam34/chip/sam4e_vectors.h: Add vector definitions for the SAM4E (2014-2-21). * arch/arm/src/sam34/chip/sam4e_memorymap.h: Add SAM4E memory map (2014-2-21). * arch/arm/src/sam34/sam4e_gpio.h, sam4e_periphclks.h, and chip/sam4e_pio.h: Add PIO support for the SAM4E (2014-2-21). * configs/stm3220g-eval/nsh/defconfig: Converted to use kconfig-frontends by Alan Carvalho de Assis (2014-2-10) * configs/*/defconfig: Comment out all CONFIG_APPS_DIR settings. These should not be set in the default configurations because we don't know where the apps/ directly will reside until configuration time (2014-2-21). * arch/arm/src/sam34/chip/sam4e_pinmap.h: SAM4E pin multiplexing definitions (2014-2-21). * sched/sched_processtimer.c and fs/procfs/fs_procfscpuload.c: Add logic to measure and calculate the CPU load percentage. From David Alessio (2014-2-22). * sched/sched_processtimer.c, sched_cpuload.c, fs/procfs/fs_procfscpuload.c, and fs_procfscpuload.c: CPU load logic extended to keep counts on each thread. The per-thread CPU is now reported in the procfs under /loadavg (2014-2-23). * include/stddef.h: ptrdiff_t is defined twice in stddef.h and also in sys/types.h. stdef.h is the correct location for the definition, but it includes sys/types.h so, at least for now, the definition will be retained in sys/types.h (2014-2-25). * net/net_close.c: Fix one place where the connection reference count was not being decremented. This is really a cosmetic change BUT when CONFIG_DEBUG_NET is enable, it will cause assertions (2014-2-25). * arch/arm/src/sama5/sam_adc.h: Fix typos in the SAMA5 ADC register definition header file (2014-2-26). * arch/arm/src/sam34: The port to the SAM4E is code complete (2014-2-16). * include/cxx: Fix some bad idempotence definitions in header files (2014-2-27). * sched/sched_cpuload.c: Change calculation of the total count when the time constant related delay elapsed. The total count is now always guaranteed to add up to 100% (excepting only truncation errors) (2014-2-27). * fs/procfs/fs_procfscpuload.c and fs_procfsproc.c: Remove the newline at the end of the percentage so that the returned strings can be printed on the same line as other values (2014-2-27). * sched/Kconfig, sched_cpuload.c, and nuttx/sched/sched_processtimer.c: An asynchronous, "external" clock may now be used to drive the CPU load calculations for more accurate load measurements when needed (2014-2-27). * configs/*/defconfig: If CONFIG_NSH_LIBRARY=y then set CONFIG_NSH_READLINE=y otherwise the CLE will be selected by default the next time that make menuconfig is used (2014-2-28). * include/cxx/cstdbool: Ignore _Bool8 if CONFIG_C99_BOOL8=y. (2014-2-28). * configs/*/defconfig: Set CONFIG_DEFAULT_SMALL on all tiny MCU configurations (2014-2-28). * configs/stm3240g-eval/nsh: Configuration converted to use the kconfig-frontends tools (2014-2-28). * configs/*/ostest: Removed most OS test configurations (except in a few cases where there was some good argument to retain the ostest configuration) (2014-2-28). * configs/stm3240g-eval/nsh2: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/stm3220g-eval/nsh2: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/stm3210e-eval/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/stm3210e-eval/nsh2: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/lincoln60/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/lpcxpresso-lpc1768/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/nucleus2g/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/vsn/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/mirtoo/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/pic32-starterkit/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/pic32-starterkit/nsh2: Configuration converted to use the kconfig-frontends tools (2014-3-1) * configs/pic32mx7mmb/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/ubw32/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/sim/nsh2: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/lm3s6432-s2e/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1) * configs/lm3s8962-ek/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/eagle100/nsh: Configuration converted to use the kconfig-frontends tools (2014-3-1). * configs/stm32f4discovery/src/Makefile: Fix typo: stm32_pwm.c not stm32_psm.c.

Only the newer configurations generated by the kconfig-frontends tools will generate viable NuttX configurations. All board configurations in the NuttX source tree have been converted to use the newer configuration, but if you have some older style configurations for you board, you will need to convert those configurations to use the kconfig-frontends tools. See http://www.nuttx.org/doku.php?id=wiki:howtos:convertconfig for some guidelines (2014-3-6). * drivers/serial/Kconfig: Correct an error introduced in this file in very recent commits (2013-3-6). * configs/*sam*: Refresh all SAM* configurations with the latest Kconfig files (2014-3-6). * configs/stm32f4discovery: Refresh all configurations (except winbuild) with the latest Kconfig files (2014-3-6). * configs/viewtool-stm32f107: Refresh all configurations with the latest Kconfig files (2014-3-6). * configs/16z, mikroe-stm32f4, olimex-lpc1766stk, px4fmu-v2_upstream, sim, and stm32f429i-disco: Refresh all configurations (2014-3-6). * Documentation/NuttShell.html: Update per recommendations from Max Kriegleder (2014-3-6). * configs/pic32-starterkit, pic32mx7mmb, stm3210e-eval, stm3220g-eval, and stm3240g-eval: Refresh all configurations with the latest Kconfig files (2014-3-7). * configs/qemu-i486/src: Files renamed to correspond with current thinking about naming (2014-3-8). * arch/x86/src/qemu/qemu_keypad.c and qemu_vga.c: New QEMU keyboard and VGA drivers from Lizhuoyi (2014-3-8). * configs/olimex-lpc2378/src: Files renamed to correspond with current thinking about naming (2014-3-8). * arch/arm/src/lpc2378/lpc23xx_i2c.c and lpc23xx_spi.c: I2C and SPI drivers for the LPC23xx from Lizhuoyi (2014-3-8). * arch/arm/include/tiva and src/tiva: The old lm/ directories were renamed tiva/ to better support new products coming down the pipe from TI (2014-3-8). * arch/arm/include/tiva, src/tiva, and configs/: All files and all all functions beginning with the name lm_ changed to tiva_ (2014-3-8). * configs/: Refresh all LM3/4/Tiva configurations (2014-3-9). * arch/arm/src/tiva/chip/tm4c_pinmap.h: Add pin multiplex definitions for the TM4C123 (2014-3-9). * arch/arm/src/tiva/chip/tm4c_memorymap.h: Add memory map for the TM4C123 (2014-3-9). * arch/arm/src/tiva/: Add GPIO and SYCONTROL register bit definitions for the TM4C123 (2014-3-10). * configs/tm4c123g-launchpad: Add basic board support for the TM4C123G-Launchpad (2014-3-10). * configs/sam4e-ek: Add basic board support for the SAM4E-EK board.

The initial commit is little more than the SAM3U-EK with name changes (2014-3-10). * configs/spark: Refresh all spark configurations (2014-3-11). * arch/arm/src/tiva/chip/tm4c_memorymap.h: Fix typos reported by Daniel Pereira de Carvalho (2014-2-12). * arch/arm/src/sam34/sam_emac.c: Add an Ethernet MAC driver for the SAM4E. The initial checkin is essentially the SAMA5D3 EMAC driver with naming changes as appropriate (2014-3-12). * arch/arm/src/sam34/sam_cmcc.c: Add logic to manage the Cortex-M Cache Control block. Untested on initial check-in (2014-3-12). * arch/arm/src/sam34/sam_emac.c: Fix EMAC pin configuration (was been set up for RMII instead of MII). Now the driver EMAC appears to be functional (2014-3-13). * configs/sam4e-ek/nsh: Networking support is now enabled by default in the NSH configuration (2014-3-13). * arch/arm/src/sam34/sam_spi.c: Backported the SAMA5 SPI driver to the SAM3/4 architecture. The SAMA5 version supports both multiple SPI peripherals as needed by the SAM3A and SAM3X and also supports DMAC (but not PDC). The initial commit is untested and may very well have (temporarily) broken SPI for the SAM3/4/ family (2014-3-13). * configs/sam4e-ek/src/sam_at25.c and sam_hsmci.c: Added support for the AT25 serial FLASH. Restructured the logic that registers the HSMCI block driver (2014-3-13). * arch/arm/src/sam34/sam_dmac.c and sam_spi.c: Fixes to DMA in general and to SPI in particular (2014-3-14). * configs/sam4e-ek/nsh: DMA-based SPI and a FAT file system on the AT25 Serial FLASH are now supported by default in the NSH configuration (2014-3-14). * sched/nanosleep.c: Fix a missing call to re-enable interrupts. From Jason Jiang (2014-3-15). 7.2 2014-04-29 Gregory Nutt * arch/arm/src/sam34/sam_udp.c and .h: Add a USB full speed device driver (UDP) for the SAM4E (2014-3-17). * Documentation/NuttxPortingGuide.html: Typo fixes from Vijay Kumar (2014-3-18). * arch/arm/Kconfig: Improved documentation of the use of the BASEPRI register from Vijay Kumar (2014-3-19). * include/nuttx/i2c.h: More typo fixes from Vijay Kumar (2014-3-19). * arch/Kconfig and *_assert.h: Add a configuration option to enable dumping of the USB trace buffer on assertion (2014-3-19). * drivers/usbdev/Kconfig, arch/arm/src/sam34/Kconfig, and drivers/usbdev/usbmsc_scsi.c: If DCD can support queuing of stall requests, then the USB MSC stall work around delays are not necessary (2014-3-20). * net/netdev_findbyaddr.c: Skip network devices that are in the "down" state. It does not make sense to consider an address match with a "down" device. From Brennan Ashton (2014-3-20). * configs/sam4e-ek/usbnsh: Add a NSH configuration that uses the NSH console (2014-3-22). * arch/arm/src/stm32/stm32_eth.c: Add IGMP hashing support. From Manuel Sthn (2014-3-24). * net/netdev_ioctl.c and uip/uip_input.c: IGMP-related bug fixes from Manuel Sthn (2014-3-24). * arch/arm/src/sam34: Add missing HSCMI configuration settings to Kconfig; update naming to include SAM34_ (2014-3-24). * configs/sam4e-ek/include/board.h: Update HSMCI timing to use the CLKODD bit (2014-3-24). * drivers/include/mtd/Kconfig, sector512.c, and include/nuttx/mtd/mtd.h: Add a new MTD driver that can be used to contain another driver and force its apparent sector size to be 512 bytes (2014-3-24). * arch/arm/src/sam34/sam_lowputc.c sam_serial.c: Fix a mysterious multithreading bug that can lock up the serial port (2014-3-14). * drivers/usbdev/Kconfig, usbmsc.c, usbmsc.h, and usbmsc_scsi.c: Redesign threading module used with the USB MSC driver. It was using pthreads before and these were changed to a kernel thread. The reason for this has to do with task grouping: A pthread is a memory of the group of the task that started it. A kernel thread is independent of the task that started in (other than knowing it as the parent). This allows me to remove so kludge logic to "deparent" the pthread on startup (2014-3-25). * tools/astyle.sh: A code formatting tool from Lorenz Meier. This tool should do a better job than the old tools/indent.sh tool (2014-3-26). * arch/arm/src/sam_hsmci.c and sam_spi.c: Add support to invalidate cached memory if the CMCC is enabled (not yet tested, 2014-3-26). * arch/arm/src/sam_spi.c: Add logic to handle SPI word widths > 8 (also untested on initial checkin, 2014-3-26). * configs/sam4e-ek: All configurations updated to run with 120MHz CPU speed and with the CMCC enabled. Calibrated delay loop (2014-3-26). * drivers/lcd/Kconfig: Add missing configuration for the MIO283QT-9A LCD. Reported by Toby Duckworth (2014-3-27). * arch/arm/include/sama5/chip.h and arch/arm/src/sama5/Kconfig: Add support for the SAMA5D36 (2014-3-28). * libc/strings/lib_strncpy.c: Change ordering of test and copy. Logic would have failed if n=0; one byte was always copying before testing for the end of the copy. * nuttx/configs/sama5d3-xplained/: Add a board support configuration for the Atmel SAMA5D3 Xplained board. The initial check in is not finished. For example, it still builds to run out of NOR FLASH but the SAMA5D Xlpained has no NOR FLASH (2013-4-28). * arch/arm/src/sama5/sam_pmc.c and .h: Add functions to calculate PLLACK, PCK, and MCK frequencies given the main clock frequency (2014-3-29). * configs/sama5d*/include/board.h, board_sdram.h, and other files: When booting from SDRAM, we need to query the PMC registers (using the functions in sam_pmc.c) to determine the MCK, PCK, etc. We assume that the MCK input clock is well known main crystal oscillator frequency (2014-3-29). * configs/sama5d3x-ek: Change all configuration names to board- specific names so that this are no name collisions with other boards that have similar configuration variables (2013-3-30). * configs/nuttx/compiler.h: Add macro UNUSED() that can be used to eliminate warnings about variables that are set to values that are not used (2014-3-30). * arch/arm/src/sama5/sam_hsmci_clkciv.c: Remove HSCMI-related functions that did not belong in sam_pmc.c and give them their own file (2014-3-30). * arch/arm/src/sama5/sam_boot.c: Fix some backward conditional compilation (2014-3-30). * libc/stdio/lib_sccanf.c: Fix a counting error in the return value from sscanf(). Noted by kfrolov. Also, sscanf() should return EOF if no values were converted (2014-3-30). * include/time.h and sched/clock_settime(): Add support for CLOCK_REALTIME. From Macs N (2014-3-31). * libc/stdio/lib_ferror.c, lib_fread.c, lib_libfflush.c, lib_libfread.c, and lib_libfwrite.c: Finish incomplete support for ferror(). From Macs N (2014-3-14). * libc/stdio/lib_ftell.c: Fix a logic error in ftell(). It was simply using the file offset and did not take into account data buffered in memory. From Macs N (2013-3-31). * Add CONFIG_CLOCK_MONOTONIC that case used to disable CLOCK_MONOTONIC for a smaller footprint (2013-3-31). * sched/Kconfig: Menu has gotten too long. And another layer of menuing in order to simplify this layer (2014-3-31). * arch/arm/src/sama5_boot.c: Fix double mapping of SDRAM when executing out of SDRAM. In this case, the SDRAM was already mapping in arm_head.S (2014-3-31). * arch/arm/src/sama5/chip/sam_dbgu.h: Add SAMA5D3 DBGU definition header file (2014-3031). * arch/arm/src/sama5/sam_dbgu.c and .h: Add support for the SAMA5D3 DBGU (2014-4-1). * configs/sama5d3-xplained/nsh: Configurations now use the DBGU for the serial console (instead of USART1) (2014-4-1). * libc/stdio/lib_sccanf.c: Use stroul() vs strol() with %u format otherwise, range of values is restricted because of sign bit from kfrolov (2014-4-2). * arch/arm/src/sama5/sam_boot.c, sam_irq.c, chip/sama5d3x_memorymap.h: When running from SDRAM, vectors must lie in SRAM (2014-4-2). * arch/arm/src/armv7-a/arm_head.S and cache.h: On start-up, make certain that the MMU and caches are disabled (probably un-necessary) (2014-4-2). * arch/arm/src/sama5/sam_boot.c: If we have to copy vectors, then make sure to clean the DCache to be sure that the copied vectors are in the physical RAM (2014-4-2). * arch/arm/src/sama5/sam_irq.c: After we modify the AXI MATRIX, make sure to invalidate all caches and TLBs (probably un-necessary) (2014-4-2). * arch/arm/src/sama5/sam_irq.c: Set the VBAR register to zero. If were started by a bootloader (vs. a RESET), then the VBAR register may not be in its reset state (zero, 2014-4-3). * arch/arm/src/sama5/sam_boot.c, sam_irq.c, and chip/sama5d3x_memorymap.h: When booting from SDRAM, don't relocated vectors to ISRAM. Instead, just set the VBAR register to address of the vectors in SDRAM. * arch/arm/src/sama5/sam_clockconfig.c: BMS Fixed to match what the HW does. From David Sidrane (2014-4-3). * arch/arm/src/sama5/Kconfig, sam_boot.c, andsam_clockconfig.c: On some hardware, reconfiguring the PLL while executing out of NOR FLASH causes crashes. This was fixed by David Sidrane by implementing RAM functions. The killer code is copied and executed from ISRAM and the crash is avoided (2014-4-3). * configs/sama5d3-xplained/Kconfig and include/board*.h; configs/sama5d3x-ek/Kconfig and include/board*.h: Add support for 528MHz CPU clock (2014-4-3). * arch/arm/src/sama5/Make.defs: Fix a build error that occurs when only USB device tracing is enabled (2014-4-4). * Documentation/UsbTrace.html: Add some discussion of the USB monitor (2014-4-4). * nuttx/arch/arm/src/armv7-a/mmu.h: Bufferable bit did not do what I thought it was going to do. Result was the NOR FLASH accesses were very slow (2014-4-3). * arch/arm/src/sama5/sam_udphs.c: Fix a case where received status was not being cleared, causing OUT SETUP commands to fail (2014-4-6). * arch/arm/src/tiva/tiva_syscontrol.c: Add logic for TM4C125GXL based on logic from Daniel Carvalho with modifications. I think the LM4F120 may have broken before as well(?). In any event, the LM4F120 also works well with this change (2014-4-7). * Back out part of 610e2aa0c224e2936fe8009ef4a2351ce607067a: Need to be able to select USB console devices when there is no /dev/console enabled. Noted by Librae (2014-4-8). * configs/*/defconfig: Increase the number of preallocated watchdogs in all configurations that use networking or USB (2014-3-9). * include/nuttx/syslog/syslog.h and ramlog.h: Move syslog.h and ramlog.h to include/nutt/syslog (2014-4-10). * sched/errno_getptr.c and getpid.c: Add some checks. If these functions are called early in initialization before the tasking structures are initialized, they will not behave properly (2014-4-10). * arch/arm/src/sama5/sam_twi.c: TWI data sending is fails to increment the number of byes transferred on first byte sent. from David Sidrane (2014-4-10). * configs/sama5d3x-ek/src: The red LED is controlled by PE24 which is also the camera/ISI interface reset line. So if the a camera is installed, then we must avoid controlling the red LED or we inadvertently also reset the camera module. Noted by David Sidrane (2014-4-11). * arch/arm/src/stm32/stm32_usbhost.c/.h and stm32_otgfshost.c: USB host tracing added by Leo (2014-4-12). * arch/arm/src/sama5/sam_adc.c, sam_can.c, sam_emac.c, sam_gmac.c, sam_ssc.c, and sam_twi.c: If running from SDRAM, then BOARD_MCK_FREQUENCY is not a constant and cannot be used in conditional compilation (2014-4-16). * drivers/lcd/mio283qt9a.c and include/nuttx/lcd/mio283qt9a.h: Update the MIO183QT-9A LCD driver to support reading from the LCD. From Toby Duckworth (2014-4-16). * arch/arm/src/stm32/chip/stm32f20xxx_pinmap.h: Correct a mapping for SPI MOSI pin. From dlsitzer (2014-4-26). * arm/src/sama5/sam_clockconfig.c and common/up_internal.h: Move the un-definitions of __ramfuncs__ from the .c file to the .h file or, otherwise, the attribute will be applied differently for the prototype and the function definition. Sourceforge patch 38 from Luciano Neri (2014-4-17). * arch/arm/src/sama5/sam_emac.c: Add missing right parentheses. This introduced in the above change and is Sourceforge patch 39 from Luciano Neri (2014-4-17). * configs/sama5dx-ek/include/board.h and sama5d3-xplained.h: These files reference type xcpt_t and so must include nuttx/irq.h. This is Sourceforge bug 25 submitted by Luciano Neri (2014-4-17). * arch/arm/src/stm32/stm32_otgfshost.c: Some fixes related to low-speed devices and interrupt endpoints from Leo (2014-4-17). * configs/stm32f4discovery/src/stm32_usb.c: Add support to register keyboard and mouse classes if so configured. From Leo (2014-4-17). * include/nuttx/usb/usbhost: Fix some USB HID-related conditional compilation. From Leo (2014-4-17). * drivers/usbhost/usbhost_hidmouse.c: Don't include NAKs from the device in the error count. From Leo (2014-4-17). * arch/arm/src/sam34/sam_irq.c: Fix initialization of the default priorities (2014-4-17). * arch/arm/src/kinetis/kinetis_irq.c, lpc17xx/lpc17_irq.c, and tiva/tiva_irq.c: Modify the logic to disables the interrupts and sets the default interrupt priority so that it uses the ICTR to get the number of interrupt lines/registers. This is instead of using some fixed number of initializations based a priori knowledge of the number of interrupt lines in the MCU. This logic is untested on some MCUs on initial check-in0 (2014-4-17). * arm/src/lpc17xx/Kconfig and lpc17_ethernet.c: The default interrupt priority should be default, not the highest priority (2014-4-19). * configs/lpcxpresso-lpc1768: Refreshed all defconfig files (2014-4-19). * configs/olimex-lpc1766stk: Refreshed all defconfig files (2014-4-19). * configs/zkit-arm-1769: Refreshed all defconfig files (2014-4-19). * include/nuttx/binfmt/ieee695.h: Beginning of header file for IEEE 695 OMF header file (2014-4-19). * arch/arm/include/stm32/chip.h and src/stm32/Kconfig: Add support for the STM401RE. From Frank Bennett (2014-4-20). * README.txt, Documentation/README.html, configs/Kconfig and README.txt, configs/nucleo-f401re: Add support for the Nucleo-F401RE board.

From Bob Doiron (2014-4-21). * configs/sam4s-xplained-pro: Boost PLLA to 240MHz to allow USB. From Bob Doiron (2014-4-21). * arch/arm/src/sam34/sam_wdt.c/.h: Add watchdog driver. From Bob Doiron (2014-4-21). * nuttx/configs/sam4s-xplained-pro: Add board-specific watchdog timer support. From Bob Doiron (2014-4-21). * drivers/timer.c and include/nuttx/timer.h: Timer "upper half" driver and lower half interface definition from Bob Doiron (2014-40-22). * arch/z16/src/z16f/z16f_espi.c: Add ZNEO ESPI driver (2014-4-24). * arch/arm/src/stm32/stm32_sdio.c: The dmaflight method must be conditioned on CONFIG_SDIO_PREFLIGHT. Noted by Pelle Windestam (2014-4-25) * configs/nucleo-f401re: Removed bogus references to the MPU (2014-4-25). * arch/z16/src/z16f_timerisr.c: Fix calculation of timer reload and prescaler. The timer frequency was way too fast (2014-4-25). * arch/arm/src/stm32/stm32_otgfsdev.c and others: Sourceforge Ticket #26. up_prioritize_irq should not be called if CONFIG_ARCH_IRQPRIO is not defined (2014-4-25). 7.3 2014-06-25 Gregory Nutt * arch/arm/src/sama5/sam_clockconfig.c: Needed function sam_pmcwait() is needed when UDPHS, EHCI, or OHCI is configured but may not be compiled in due to insufficient conditional logic. From Luciano Neri (SourceForge patch #40) (2014-4-29). * arch/arm/include/stm32/chip.h, src/stm32/Kconfig, stm32_allocateheap.c, configs/nucleo-f401re/nsh/defconfig, and scripts/ld.script: Numerous changes, most correcting memory usage on the Nucleo-F401RE (2014-4-30). * /drivers/mtd/w25.c: Extended by Mark Whitehorn to support the 8Mbit W25Q80BV part (2014-4-30). * configs/sam4s-xplained-pro: Update LED control logic from Bob Doiron (2014-4-30). * drivers/timer.c and include/nuttx/timer.h: Enhanced timer interface from Bob Doiron (2014-4-30). * arch/arm/src/sam34/Kconfig and sam_tc.c: Enhanced timer/counter driver from Bob Doiron (2014-4-30). * configs/sam4s-xplained-pro/Kconfig, nsh/defconfig, and src/sam_tc.c: The SAM4S Xplained Pro now uses the extended timer/counter features. From Bob Doiron (2014-4-30). * include/nuttx/arch.h and sched/os_internal.h: If the CPU load measurements are being driven by an external clock, then the prototype for sched_process_cpuload() must be available in include/nuttx/arch.h (2014-4-30). * Documentation/NuttShell.html and many defconfig files: The alternate console device CONFIG_NSH_CONDEV must not be defined unconditionally. This causes errors when using Telnet sessions. This was solved by adding CONFIG_NSH_ALTCONDEV: CONFIG_NSH_ALTCONDEV enables or disables the feature then, if enabled, CONFIG_NSH_CONDEV provides the alternative console device name (2014-5-5). * arch/arm/src/sam34/sam_rtt.c/.h: RTT driver from Bob Doiron. Also added high resolution RTC emulation using the RTT for the sub-second counter (2014-5-5). * configs/sam4s-xplained-pro: Clean-up of LED usage and also some integration of new timer features. From Bob Doiron (2014-5-5). * drivers/timer.c and include/nuttx/timer.h: Timer driver updates from Bob Doiron (2014-5-5). * binfmt/symtab_findorderedbyname.c: Fix an error in the symbol search function. Noted by Pelle Windestam (2014-5-6). * arch/arm/src/stm32/stm32f40xxx_rcc.c and configs/nucleo-f401re/include/board.h: The Nucleo-F401RE has no on-board crystals and, hence, needs to run with the PLL input from the on-chip HSI clock (2014-5-6). * arch/arm/src/armv7-a/arm_memcpy.S: This is the same optimized memcpy() function that Mike Smith brought in for the ARMv7-M with minor tweaks by David Sidrane to work with the ARMv7-A (2014-5-6). * binfmt/libpcode, pcode.c, include/nuttx/poff.h, and binfmt/pcode.h: Framework to support Pascal P-Code as a binary format. At present this logic is incomplete and really nothing more than a thought experiment to determine the feasibility of the P-code binary format (2014-5-7). * drivers/sensors/Make.defs: Correct build dependency. Sourceforge ticket #41 from Kosma Moczek (2014-5-8). * drivers/serial.c, include/nuttx/serial.h, arch/arm/src/stm32/stm32_serial.c and minor updates to all other drivers using the serial interface: Add an rxflowcontrol method to the serial interface to better support RX flow control. From Jussi Kivilinna (2014-5-8). * arch/arm/include/stm32 and src/stm32: Add support for the STM32152 and STM32162 Medium+ density parts (plus miscellaneous other improvements to the original STM32151 logic). From Jussi Kivilinna and Sami Pelkonen (2014-5-8). * binfmt/binfmt_dumpmodule.c, binfmt_loadmodule.c, binfmt_unloadmdoule.c, builtin.c, elf.c, nxflat.c, pcode.c, and include/nuttx/binfmt/binfmt.h: Extend the binfmt interface to handle error conditions where format-specific binfmt clean-up is needed in the event of error conditions. This is needed by the P-Code binfmt (2014-5-8). * binfmt/libpcode, pcode.c, include/nuttx/poff.h, and binfmt/pcode.h: Now uses apps/interpreters/prun and is basically functional. More work is needed because (1) it is too coupled with apps/ and (2) will not work with CONFIG_NUTTX_KERNEL (2014-5-9). * arch/arm/src/stm32/stm32_i2c.c: Bring in PX4 fix for I2C in very high noise environments or with rogue perpipherals. Taken from the PX4 commit 099b2017ccfa0fc7696f168db2a0c2e13fe5edbc by Tridge here: https://github.com/PX4/NuttX (2014-5-10). * include/nuttx/video/rgbcolors.h: Fix typo in several macros: RBG -> RGB. (2014-5-12). * drivers/mtd/ramtron.c: Add support for Fujitsu MB85RS1MT part. From Charles Ash (2014-5-12). * configs/sam4e-ek/src/sam_ili9325.c: Add an LCD driver for the SAM4E-EK board. Untested on initial check-in (2014-5-13). * configs/sam4e-ek/src/sam_ads7843e.c: Add a touchscreen driver for the SAM4E-EK board. Untested on initial check-in (2014-5-13). * arch/arm/src/stm32/stm32_i2c_alt.c: Add an alternative I2C implementation for the STM32 F03 that works around errata in that part. From Patrizio Simona (2014-5-14). * arch/arm/src/sam34/sam_gpio.c: Fix some SAM4E compiler errors when CONFIG_DEBUG_GPIO is enabled (2014-5-15). * sched/sig_mqnotempty.c: Test for a valid signal number is inverted; this function could not have been working correctly??? From eero.nurkkala (2014-5-20). * arch/arm/src/stm32/stm32_lowputc.c: Fix error in conditional compilation. From Sami PelKonen (2014-5-20). * arch/*/src/* (several files): Make sure that all references to up_prioritize_irq() are conditioned on CONFIG_ARCH_IRQPRIO. Problem noted by Mike Smith (2014-05-20). * drivers/wireless/cc3000/Kconfig: Correct SPI mode for CC3000 is CPOL=0 CHPA=1. See http://processors.wiki.ti.com/index.php/CC3000_Serial_Port_Interface_(SPI) From Jussi Kivilinna (2014-5-21). * drivers/wireless/cc3000/cc3000.c and include/nuttx/wireless/cc3000/include/cc3000_upif.h: Configuration has CC3000_SPI_MODE settings but source uses CONFIG_CC3000_SPIMODE. From Jussi Kivilinna (2014-5-21). * drivers/wireless/cc3000/cc3000drv.c: unsoliced_thread does initialization of message queue, but main thread might block that thread from running and use the uninitialized message queue. The main thread must wait until unsolice_thread initializes the required structures before proceeding. From Jussi Kivilinna (2014-5-21). * drivers/wireless/cc3000/cc3000.c: Fix build when POLL is enabled. From Jussi Kivilinna (2014-5-21). * arch/arm/include/armv7-m/irq.h: Change bne to bne.n in irqrestore() (2014-5-22). * Many files: Convert all old-style variadic macros to the C99 form. Recent GCC changes tightens up that behavior and can cause some problems (at least for the IAR compiler for some reason). See https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html#Variadic-Macros. Noted by Bob Grimes (2014-5-22). * configs/viewtool-stm32f107/nsh: Configuration refreshed (2014-5-23). * arch/arm/src/stm32/stm32_i2c_alt.c: Final driver from Max Kriegleder et al. Reduces footprint and fixes a bug. (2014-5-23). * tools/configure.sh: In-place SED edit messes up permissions on windows. From Hannes Delago (2014-5-25). * include/nuttx/mtd/mtd.h: Needs forward reference to struct spi_dev_s. (2014-5-25). * arch/arm/src/stm32/stm32_i2c.c and stm32_i2c_alt.c: Back out PX4 fixes that were reverted in the PX4 repositories (2014-5-25). * sched/Kconfig: CONFIG_START_YEAR/MONTH/DAY are not required if the RTC is enabled (2014-5-26). * arch/arm/src/stm32/stm32_rtcc.c: Add retry logic to RTC initialization. It sometimes takes longer for the RTC to initialize, at least as noted on an F2 part. From dlsitzer (2014-5-27). * libc/stdio/lib_snprintf.c: If the size passed to snprintf() is zero, then snprintf() must write nothing, but instead return the size of the buffer needed to hold the entire string.

From Max (himax) (2014-6-23). * net/tcp/Kconfig: Cannot enable bother TCP write buffering AND raw packet sockets. This should not logically be the case, but is because the implementations are presently too coupled. The logic packet socket logic in net/net_send_unbuffered.c needs to be broken out into a separate file so that write buffered TCP and packet socket transfers can co-exist (2014-6-23). * net/uip/uip_pktsend.c: Move the logic that copies data into the device buffer from net/net_send_unbuffered.c to net/uip/uip_pktsend.c.

From Kosma Moczek (2014-6-30) * include/unistd.h: Some POSIX_* and _POSIX_* macros are defined without value, whereas (as far as I can tell) the newer versions of the standard require them to have the value corresponding to the standard version implemented, like 200809L. Are the any plans to clean this up? For now I've put together a quick patch that defines those macros to 1, consistent with the rest of unistd.h. From Kosma Moczek (2014-6-30) * arch/arm/src/sama5/sam_memories.c: Fix some logic in conversion of physical and virtual DRAM addresses when running out of DRAM.

Re-vision PCM structure definition (2014-7-22). * configs/sama*: Disable MMC/SD multiblock transfers in all SAMA5D3/4 configurations. I suspect an issue but have not had time to run it down yet so the easiest thing is simply to disable the feature for now (2014-7-23). * drivers/audio/audio_null.c, include/nuttx/audio/audio_null.c, and configs/sama5d4-ek/src/sam_audio_null.c: Add a NULL audio device that can be used to simply unit-level testing of audio decoders (2014-7/23). * audio/pcm_decode.c, include/nuttx/audio/audio.h, and drivers/audio/audio_null.c and wm8904.c: Add ioctls so that PCM decoder can configure the driver bitrate, num channels, and sample width (2014-7-23). * drivers/audio/Kconfig: Fix a typo in the audio Kconfig file, UDIO->AUDIO (2014-7-23). * configs/sama5d4-ek/nxwm/defconfig: The NxPlayer and audio system are now enabled in the default configuration (although they have not yet been fully integrated into the NxWM media player) (2014-7-23). * configs/sama5d4-ek/nsh/defconfig: Enable the command line media player in the NSH configuration as well (still does not work, however) (2014-7-23). * audio/Kconfig, audio.c, and include/nuttx/audio/audio.h: Add hooks for fast-forward and rewind needed by CMediaPlayer; add hooks for equalizer settings needed by the WM8904 (2014-7-24). * drivers/audio/audio_null.c and wm8904.c: Fix some compile errors when audio DEBUG is enabled (2014-7-24). * SAMA5D4-EK NxWM: Configuration refreshed (2014-7-24). * arch/arm/src/armv7-m/up_initialstate.c: Correct the initial value of the BASEPRI register. This was apparently never being initialized! From Max (2014-7-24). * configs/mbed/src/up_adc.c, up_dac.c, and up_pwm.c and include/board.h: Port ADC, DAC, and PWM logic from the configs/zkit-arm-1769. From Max (2014-7-24). * arch/arm/src/lpc17xx/lpc176x_rtc.c: Eliminate warnings. From Max (2014-7-24). * arch/arm/src/lpc17xx/lpc17_pwm.c, lpc17_timer.c, lpc17_dac.c: Mostly cosmetic updates from Max (2014-7-24). * arch/arm/src/lpc17xx/lpc17_adc.c and Kconfig : Added burstmode ADC conversion mode, with CONFIG_ADC_BURSTMODE option in Kconfig. From Max (2014-7-24). * arch/arm/src/lpc17xx/lpc17_ethernet.c: Added option to use the kernel worker thread to do most of the workload with CONFIG_NET_WORKER_THREAD option in Kconfig. Eliminated a problem with PHY DP83848C : it doesn't need a specific initialization on mbed. Critical bugfix: From time to time (after some hours) the Ethernet receiver would lose one receive interrupt and the IP stack never recover because there is no receive watchdog as the transmit watchdog. From Max (2013-7-24). * audio/pcm_decode.c: Add missing audio callback forwarding logic (2014-7-25). * arch/arm/armv7-a/l2cc_pl310.h: Move arch/arm/sama5/chip/sam_l2cc.h to arch/arm/armv7-a/l2cc_pl310.h. Adjust the two corresponding Kconfig files as well (2014-7-25). * arch/arm/src/armv7-a/arm_l2cc_pl310.c, l2cc.h, l2cc_pl310.h, Kconfig: Add initial support for the ARM L2CC-PL310 L2 cache (2014-7-26). * arch/arm/src/armv7-a/cp15_cacheops.h: Rename ARMv7-A cache.h to cp15_cache.h. Things will be broken on this commit until I get the new cache.h in place (2014-7-26). * arch/arm/src/armv7-a/cache.h: New cache.h file. Renames all functions like cp15_XYZ_cache() to arch_XYZ_cache() and adds L2 cache support if L2 cache is enabled (2014-7-26). * arch/arm/src/sama5/*.c (many files): Change naming from cp_XYZ_cache() to arch_XYP_cache() so that all cache operations will pick up L2 support if it is enabled (2014-7-26). * arch/arm/src/sama5/sam_boot.c: Enables cache early in boot-up sequence (2014-7-26). * arch/arm/src/armv7-a/arm_l2cc_pl310.c and l2cc.h: Minor bugfixes/ improvements (2014-7-26) * arch/arm/src/armv7-a/Kconfig: L2 Cache currently depends on EXPERIMENTAL because it does not yet work properly (2014-7-26). * include/nuttx/audio/audio.h: Move sub-sampling rate definitions from nxplayer.h to audio.h (2014-7-17). * audio/pcm_decode.c: PCM: First cut at fast forward by sub-sampling. This design is overkill: It manages too many audio buffers. I think that a cleaner design could do all sub-sampling in place without managing additional audio buffers (2014-7-27). * drivers/audio/audio_null.c: Was not returning buffers to the upper level (2014-7-27) * include/nuttx/audio/audio.h and audio/pcm_decode.c: Misc bugfixes while integrating fast forward by sub-sampling (2014-7-27). * audio/pcm_decode.c: Back out a change; the fix really belongs in NxPlayer. (2014-7-27). * arch/arm/src/lpc17xx/lpc17_adc.c and arch/arm/src/lpc17xx/lpc17_ethernet.c: ADC updates from Max. Also fixes some syntax errors that I introduced in the last commit (2014-7-28). * audio/pcm_decode.c: Fix a logic error in a DEBUG assertion (2014-7-28). * configs/sama5d4-ek/src/sam_pmic.c, dram_main.c, sama5d4-ek.h, Makefile. Add logic to disable the faulty PMIC. This must be done with JP23 open. It is performed only from the DRAMBOOT loader (2014-7-28). * drivers/audio/wm8904.c: Fix some compile problems with the WM8904 driver due to recent audio subsystem changes (2014-7-28). * arch/arm/src/sama5/sam_timerisr.c and configs/sama5d3*/include/board*.h: Correct system timer frequency. Input clock is MCK/2, not MCK (2014-7-29). * fs/fs_automount.c and include/nuttx/fs/automount.h (plus hooks in other files): Add support for an auto-mounter that will automatically mount and unmount a file system a media is inserted and removed (2014-7-29 . * configs/sama5d4-ek/src/sam_automount.c: Add automounter support for HSMCI0 and HSMCI1 (2014-7-29). * configs/sama5d4-ek/Kconfig and src/sam_hsmci.c: Minor warning/latent bug clean-up of auto-mounter logic (2014-7-29). * configs/sama5d4-ek/README.txt anand src/sam_nsh.c, fs/fs_automount.c, and include/nuttx/fs/automount.h: Cosmetic updates to comments and README files and some naming (2014-7-29). * configs/sama5d4-ek/nsh/defconfig and nxwm/defconfig: The SAMA5D4-EK NSH and NxWM configurations now have the auto-mounter configured to automatically mount the FAT file system on HSMCI0 at /mnt/sdcard (2014-7-29). * arch/arm/src/sama5/sam_hsmci.c: Add method to do RX transfer without DMA. The 8-byte SCR transfer was failing silently with the DMA transfer, leaving the SD card in single bit mode (2014-7-29). * arch/arm/src/sama5/sam_hsmci.c: Fix a problem on card insertion/removal callback handling. Interrupts were being disable so that the callbacks occurred with interrupts disabled. This resulted in loss of some interrupts and some not-so-good behaviors. The solution is to perform all callbacks on the work thread unconditionally (2014-7-30). * nuttx/fs/fs_automount.c: Auto-mounter: Fix state setting. Not harmful other than it can cause a debug assertion to fire if you manually unmount the media before removing it which is, of course, what you are supposed to do (2014-7-30). * arch/arm/src/sama5/sam_hsmci.c and README files: Re-enable TX DMA and verify that DMA writes to the SD card are functional. They are so now TX DMA is re-enabled in the driver. This might affect the SAMA5D3 platforms where the TX DMA problem was found. The SAMA4D3 and 4 use the same HSMCI driver. Much has change since then and it is not surprising that DMA is now functional. However, the has not be re- verified on the SAMA5D3 which has a different DMA controller (2014-7-30). * arch/arm/src/sama5/sam_dmac.c, sam_pio.c, and sam_pioirq.c: Changes needed for a clean SAMA5D3 build after all of the recent SAMA5D4 changes (2014-7-31). * configs/sama5d3x-ek/nsh/defconfig: Refresh configuration (2014-7-31). * configs/sama5d3x-ek/Kconfig, README.txt, src/sam_wm8904.c, Makefile, sam_nsh.c, and sama5d3x-ek.h: Add support for the WM8904 audio CODEC (2014-7-31). * configs/sama5d3x-ek/nxplayer: Add a configuration to support the command line NxPlayer (2014-7-31). * audio/audio.c: More debug output (2014-7-31). * configs/sama5d3x-ek/README.txt: REAME update (2014-7-31). * drivers/audio/wm8904.c: Was not saving I2S interface instance (2014-7-31). * sched/sem_wait.c: Use set_errno() and get_errno(). Direct access inside the OS may not be supported in the future (2014-7-31). * drivers/audio/audio_null.c, vs1053.c, wm8904.c, include/nuttx/audio/audio.h, libc/audio/lib_buffer.c: Change how the end of the audio stream is detected by the leaf audio component. This used to be done by looking for the first partial buffer. That does not work with the in-place sub-sampling performed by the PCM decoder: That always reduces the size of the buffer so that all buffers only partially filled by the time they get to the leaf. Now, a flag is set in the audio buffer flags set to indicate the final buffer in the stream (2014-7-31). * arch/arm/src/sama5/sam_ssc.c: Needs to account for data offset in audio buffer (2014-7-31). * drivers/audio/wm8904.c: Can't reset the WM8904 unless we also reinitialize all registers. Try to get a saner timeout based on sample rate, bits-per-sample, and buffer size (2014-7-31). * arch/arm/src/sama5/Kconfig and sam_ssc.c: SCC Frame Synch Delay and Start Delay are now configurable (2014-8-1). * drivers/audio/wm8904_debug.c: Add logic to dump WM8904 registers (2014-8-1). * drivers/audio/wm8904.c: Fix an error in write logic. I am not sure why this fixes the problem (2014-8-1). * include/nuttx/audio/wm8904.h (and implementers of the interface): the WM8904 driver needs to know the frequency of the MCLK in order to set up the FLL to generate the correct bitrate (2014-8-1). * WM8904: Add an option to control WM8904 register dumping (2014-8-2). * WM8904: Add logic to program the FLL to achieve the bitrate (2014-8-1). * arch/arm/src/sama5/sam_ssc.c: Verify that the requested bit width is supported. Correct some alignment tests that depend upon the data bit width (2014-8-2). * audio/pcm_decode.c: Correct the end of audio stream handling. It was not being detected before so that logic was not examining the WAV header in the first buffer of the next audio file (2014-8-2). * configs/sama5d3x-ek/nxplayer/defconfig: Update with last WM8904 settings (2014-8-2). * drivers/audio/wm8904.c: Disable the FFL at the end of playing (2014-8-2). * include/nuttx/audio/wm8904.h: Fix wm8904_dump_registers macro: Wrong number of parameters (2014-8-2). * arch/arm/src/sama5/sam_pck.* and all SAMA5D board header files: Add Main clock as an option for the PCK clock source (2014-8-3). * configs/sama5d*-ek/Kconfig and src/sam_wm8904.c: Add option to use MAINCK as source fort he WM8904 MCLK (2015-8-3). * include/nuttx/audio/wm8904.h, configs/sama5d3x-ek/src/sam_wm8904.cm, and sama5d4-ek/src/sam_wm8904.c: WM8904 interface enable method now returns the previous interrupt state (2014-8-4). * configs/sama5d3x-ek/src/sama5d3x-ek.h and sama5d4-ek/src/sama5d4-ek.h: Correct the WM8904 interrupt configuration, active high level. Fix that and don't pull-up (2014-8-4). * configs/sama5d3x-ek/src/sam_wm8904.cm, and sama5d4-ek/src/sam_wm8904.c: Correct ordering of some WM8904initialization: Need to provide MCLK before initializing the WM8904, not after (2014-8-4). * drivers/audio/wm8904.c and .h: Correct calculation of bitrate (I am not sure why this is correct). LR clock divisor is now a constant 32- bits per frame. Conditioned out interrupt logic; it is not being used. Also added some FLL lock interrupt/poll logic (which was subsequently disabled) (2014-8-4). * SAMA5D3x-EK and SAMA4D4-EK: Add/update usage documents for media players (2014-8-4). * drivers/audio/wm8904.c and .h: Add reset logic to put the part back in its initial state after playing each WAV file. Base samples per second on frame length, not bits-per-sample. Use a different frame length for 8-bit and 16-bit data (2014-8-4). * arch/arm/src/sama5/sam_hsmci.c: TX DMA is again disabled for the SAMA5D3 family. Although it works with the SAMA5D4 (which has a different DMA subsystem), it does not work with the SAMA5D3 (2014-8-5, see also 2014-7-30). * audio/pcm_decode.c: Handle errors in the PCM WAV file in a way that the Nxplayer can recover gracefully: Send and Audio Complete message (2014-8-5). * arch/*/src/*/*_timerisr.c, up_initialize.c, and up_internal.h: Re-name up_timerinit() to up_timer_intialaize() for compatibility with new tickless OS interface name (2014-8-6). * arch/*/src/*/Make.def: Don't build existing timer initialization logic if CONFIG_SCHED_TICKLESS is defined (2014-8-6). * include/nuttx/arch.h: First cut at platform-specific interfaces needed to support tickless OS option (2014-8-6). * sched/Kconfig: Add a new option CONFIG_SCHED_TICKLESS to enable the tickless OS. This is a work in progress but should be relatively safe since the new features are only enabled by this option (Safer but not 100% safe since it does not protect from typos and other dumb errors) (2014-8-6). * arch/sim/src/Makefile, up_idle.c, up_internal.h, and up_tickless.c: Add support for a simulated interval timer support verification of the tickless OS (2014-8-6). * include/nuttx/arch.h: Added another tickless OS interface to get the timer remaining on the interval timer (2014-8-6). * include/nuttx/clock.h, sched/clock_initialize.c and clock_internal.h: If CONFIG_SCHED_TICKLESS is defined, then the global variable g_system_timer does not exist (2014-8-6). * sched/Makefile: Don't build in sched_processtimer.c if CONFIG_SCHED_TICKLESS is selected (2014-8-6). * sched/clock_gettime.c and clock_settime.c: Use the clock_systimer() macro, do access the g_system_timer() global directly (2014-8-6). * sched/clock_systimer.c: Uses interval timer interfaces to get the time if CONFIG_SCHED_TICKLESS is selected (2014-8-6). * sched/sched_timerexpiration.c, Makefile, os_internal.h, sched_addreadytorun.c, sched_processtimer.c, sched_unlock.c, wd_cancel.c, wd_internal.h, and wd_start.c: Implements the tickless OS (2014-8-7). * Many files: Remove CONFIG_DISABLE_CLOCK. Why? This option is not really very useful and was only selected in a few unusable, mostly unusable configurations anyway (m9s12/ostest, kl25z/minnsh, z180/ostest, 8051, sh1, z80, and z8). The only real loss is probably to the kl25z/minsh configuration . And with the addition of the tickless OS, I just wanted to make the pain go away (2014-8-7). * Many files: Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new integer overflow problems 2014-8-7). * Many files: Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion (2014-8-7). * arch/sim/src/up_tickless.c and sched/sched_timerexpiration.c: The tickless OS now appears fully functional and passes the OS test on the simulator with no errors (2014-8-7). * sched/mqueue: Move POSIX message queue files from sched/ to sched/mqueue (2014-8-8). * sched/signal: Move signal-related files from sched/ to sched/signal (2014-8-8). * sched/pthread: Move all pthread files from sched/ to sched/pthread (2014-8-8). * sched/semaphore: Move POSIX counting semaphore files from sched/ to sched/semaphore (2014-8-8). * sched/environ: Move environment files from sched/ to sched/environ (2014-8-8). * sched/group: Move group logic from sched/ to sched/group (2014-8-8). * sched/wdog: Move watchdog functions from sched/ to sched/wdog (2014-8-8). * sched/irq: Move interrupt dispatch logic from sched/ to sched/irq (2014-8-8). * sched/clock: Move clock functions from sched/ to sched/clock (2014-8-8). * sched/timer: Move POSIX timer files from sched/ to sched/timer (2014-8-8). * sched/paging: Move page fill sources from sched/ to sched/paging (2014-8-8). * sched/init: Move initialization functions from sched/ to sched/init (2014-8-8). * sched/errno: Move errno related files from sched/ to sched/errno (2014-8-8). * sched/task: Move task control files from sched/ to sched/task (2014-8-8). * sched/: Move a few files in sched/ that did not seem to have a home to sched/signal and sched/task (2014-8-8). * sched/sched: Move scheduler files from sched/ to sched/sched (2014-8-8). * (Many files): Replace os_internal.h with sched/sched.h in files that actually reference something in sched.h (2014-8-8). * sched/task/exit.c: Move sched/exit.c to sched/task/exit.c (2014-8-8). * (Many files): Remove os_internal.h it has been replace by several new header files under sched/. There have been some sneak inclusion paths via os_internal.h, so expect a few compilation errors for some architectures (2014-8-8). * Documentation/NuttxPortingGuide.html, arch/sim/src/up_tickless.c, and include/nuttx/arch.h: Fix errors in documentation and comments related to the Tickless OS. From Vijay Kumar (2014-9-9). * arch/arm/src/sama5/sam_tc.c and .h: Can now handle non-constant BOARD_MCK_FREQUENCY. Also now supports methods to attach user interrupt handlers (2014-8-9). * drivers/audio/audio_null.c: Fix an error in a variable name (2014-8-9). * arch/arm/src/sama5/sam_oneshot.c, .h, Kconfig, Make.defs, sam_tc.c, .h, and sam_adc.c: Add support for a one-shot timer wrapper around the low-level timer/counter logic. This also involved several changes that rippled into the ADC driver (untested) (2014-8-9). * arch/arm/src/sama5/sam_freerun.c, .h, Kconfig, and Make.defs: Add support for a free-running timer wrapper around the low-level timer/counter logic (2014-8-9). * arch/arm/Kconfig, src/sama5/sam_tickless.c, Kconfig, Make.defs: Use the one-shot and free-running timers to implement tickless OS support for SAMA5 (2014-8-9). * arch/arm/src/sama5/sam_oneshot.c and sam_tc.c: Fix several bugs in timer/counter interrupt logic and one-shot timer logic. Comments and debug output updated in additional files (2014-8-10). * sched/wdog/wd_start.c: Correct a bug in Tickless OS support: logic to detect changes in head of timer list was wrong (2014-5-10). * sched/sched/sched_timerexperation.c, sched.h, and wdog/wd_start.c: In tickless mode, need to stop the interval timer before inserted a new delay into the timer list. Otherwise, the time is incorrect on the first entry of the list (2014-8-11). * arch/arm/src/sama5/sam_freerun.c and sam_oneshot.c: Correct bad time conversion, 1000000 not 1000 to convert seconds to microseconds (2014-8-11). * sched/sched/sched_timerexpiration.c: Fix inaccurate time conversion. Remove MSEC_PER_TICK from calculation and convert uint32_t to uin64_t (2014-8-11). * libc/time/lib_localtime.c, private.h, tzfile.h and several header and make-related files: Adds support for localtime. From Max Neklyudov (2014-8-12) 7.5 2014-09-28 Gregory Nutt * clock/clock_systimespec.c and sched/clock/clock_gettime.c: When reading the system timer, don't read a struct timespec, convert it to a fake tick count, then back to a timespec (2014-8-15). * sched/clock/Make.defs, clock_gettime.c, clock_settime.c, include/time.h, nuttx/clock.h, configs/vsn/src/sif.c: Remove CLOCK_ACTIVETIME. It is non- standard, unused, and gets in the way of maintaining clocks (2014-8-15). * libc/time/lib_localtime.c: Modified to that the coding style is much closer to NuttX coding style. The local header files private.h and tzfile.h were removed and incorporated into lib_localtime.c. All conditional compilation within lib_localtime.c that unconditionally evaluated to FALSE was removed (2014-8-15). * drivers/net/Kconfig and include/nuttx/arch.h: Standardize a PHY interrupt attachment interface (2014-8-16). * configs/Kconfig, sama5d3-xplained, sama5d3x-ek, and sama5d4-ek: Convert existing board specific PHY interrupt interfaces to use newly defined standard interface (2014-8-16). * include/net/slip.h: Move SLIP prototypes from net.h to slip.h (2014-8-16). * include/net/net.h and net/: Fix some missing function headers (2014-8-16). * drivers/net/phy_notify.c, include/nuttxarch.h, net/phy.h, and ioctl.h: Add support for an ioctl that can be used to notify an application when there is a change in the network status signalled by a PHY interrupt (2014-8-16). * drivers/net/phy_notify.c, include/net/if.h, ioctl.h, netdev.h, phy.h, and net/netdev/netdev_ioctl.c: Finishes the ioctl definition to subscribe to PHY events. Revamp network ioctl signature to support arguments other than struct mii_ioctl_data (2014-8-16). * arch/arm/src/stm32/stm32_eth.c: Modified to support the change to the network ioctl signature changes. Also add support for new ioctl to setup PHY event notifications (2014-8-16). * arch/arm/src/sama5/sam_emaca.c, sam_emacb.c, and sam_gmac.c: Implement all network ioctls, including the new ioctl to setup PHY event notifications (2014-8-16). * include/net/if.h: Add some helper macros to make the code that uses the ioctls a little more compact (2014-8-17). * libc/stdio/lib_sscanf.c: NuttX libc tried to guess how many characters to parse, extracted them into a buffer, then ran strtol() on that buffer. That guess is often wrong. A better approach would be to call strtol() directly on the input data, using the endptr return value to determine how many characters to skip after parsing. From Kosma Moczek (2014-8-18). * net/arp/arp_dump.c: Add missing configuration option to select dumping of ARP packet headers. Move ARP dumping logic from arp_inout.c to its own file (2014-8-18). * net/arp/arp_out.c: Move arp_out() from arp_inout.c to its own file (2014-8-18). * net/arp/arp_arpin.c: Move arp_arpin() from arp_inout.c to its own file (2014-8-18). * net/arp/arp_ipin.c: Rename arp_inout.c to arpipin.c because that is all that is left in the file (2014-8-18). * net/arp/arp_format.c: Move the logic that formats an ARP packet into a separate file where it can be re-used. (2014-8-18). * net/arp/arp_out.c and net/pkt/pkt_send.c: Change how the IFF_NOARP flag is handled. This should be set only when data is moved into the buffer and cleared after tested by the ARP logic. Setting it globally can cause packets to be sent with no valid MAC addresses (2014-8-18). * net/arp/arp_send.c: Partial implementation of logic to send ARP requests to assure that an IP address mapping is present in the ARP table (2014-8-18). * net/arp/arp_poll.c: Finished the implementation of logic to send ARP requests. Complete, fully hooked into the networking logic, and ready for test (but still untested) (2014-8-18). * net/icmp/icmp_ping.c, net/socket/net_sendfile.c, sendto.c, net/tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c: If CONFIG_NET_ARP_SEND is enabled, then all ICMP, TCP, and UDP send operations will call arp_send() before attempting the real send operation. arp_send() will check if the IP address mapping is in the ARP table and, if not send ARP requests periodically until it is. This eliminates losing the first outgoing message because there is not mapping in the ARP table (2014-8-18). * net/arp/arp_notify.c, arp_send.c, arp_arpin.c, and arp.h: Add signalling logic so that we do not have to wait so long with the network responses to ARP requests quickly (2014-8-19). * include/nuttx/lcd/ili9341.h: Add a register definition header file for the ILI9341 LCD (2014-8-19). * net/arp/Kconfig: ARP request logic is no longer EXPERIMENTAL (2014-8-20). * net/arp/arp_send.c: ARP request logic needs to do the right thing if (1) the address is a broadcast or multicast address, and (2) if the IP address lies outside of the network. Problem noted by Manuel Stuehn (2014-8-20). * configs/sam4e-ek/src/Kconfig and src/sam_ili9341.c: Add ILI9341-based LCD driver. Fully functional (2014-8-20). * configs/sam4e-ek/nxwm: Add an NxWM configuration for the SAM4E-EK (2014-8-21). * configs/viewtool-stm32f107: Refresh some configurations (2014-8-20). * nuttx/sched/wdog: If we run out of pre-allocated watchdog times, the logic will allocate additional timers from the heap. A reserve of pre-allocated watchdog timers is maintained so that there will always be timers available for interrupt handlers (2014-8-21). * include/nuttx/wdog.h (and many affected files): wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx (2014-8-21). * Documentation/NuttxPortingGuide.h: For the same reason as above, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide (2014-8-21). * arch/arm/src/stm32/stm32_uart.h: STM32 F401: Correct support for USART6 on this chip. From Freddie Chopin (2014-8-22). * nuttx/sched/wdog and include/nuttx/wdog.h: Add support for statically allocated watchdog timer (also eliminate some unconventional typing) (2014-8-22). * configs/p112/ostest and tools/mkdeps.c: Changes to try to get P112 to compile with latest SDCC (it still does not) (2014-8-22). * sched/group/group_leave.c: Need to release the address environment when the task group is released (2014-8-22). * mm/mm_granreserve.c and and mm_granmark.c: gran_reserve(): Add a new function to reserve unallocatable regions in the granule heap (2014-8-23). * include/nuttx/pgalloc.h and mm/mm_pgalloc.c: Add a simple page allocator based on the existing NuttX granule allocator. I am not certain if the granule allocator is sufficiently deterministic for long range use, but it gets get a page allocator in place for testing very quickly (2014-8-23). * ARMv7-A: Add skeleton implementation and build support for process address environments (2014-8-23). * Many files: Change CONFIG_ADDRENV to CONFIG_ARCH_ADDRENV; change how it is selected -- the architecture must first declare support (2014-8-24). * include/nuttx/addrenv.h, arch/arm/include/arch.h, armv7-a/irq.h, and other files: Add addrenv.h; First cut at Cortex-A address environment structures; Add configuration options to setup address environment (2014-8-24). * addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext() and up_addrenv_vdata(). Affects several files (2014-8-24). * arch/arm/src/armv7-a/arch_coherent_cache.c: New file. These cache operations are called from the ELF loader in order to flush D-cache and invalidate I-cache after an ELF module has been loaded into memory. With this change, ELF modules work correctly on the SAMA5/Cortex-A platform (2014-8-24). * configs/sim: Add build support for ELF modules. Useless at the moment because there is no x86 relocation logic support (2014-8-25). * configs/sim: Update some sim/ defconfig files. This now automatically switches them to x86_64 builds (2014-8-25). * arch/arm/include/arch.h, armv7-a/irq.h, src/armv7-a/arm_addrenv.c, armv7-a/arm_mmu.c/.h, sama5/Kconfig, Make.defs, sam_pgalloc.c, include/nuttx/addrenv.h, arch.h, pgalloc.h, mm/Kconfig, mm_pgalloc.c, sched/init/os_start.c: Cortex-A/SAMA5 address environment support is code complete (untested) (2014-8-25). * arch/arm/include/tiva and src/tive: Add support for the TI CC3200. From Jim Ewing (2014-8-26). * configs/cc3200-launchpad: Add support for the TI CC3200 Launchpad. From Jim Ewing (2014-8-26). * arch/*/*_blocktask.c, arch/*/*_unblocktask.c, and arch/*/*_exit.c: Add address environment support to all implementation of up_block_task(), up_unblock_task(), and _exit() (2014-8-31). * arch/arm/src/stm32/stm32_flash.c and chip/stm32_flash.h, include/nuttx/progmem.h, and configs/vsn/src/sif.c: STM32 FLASH fixes: use size_t instead of uint16_t, make interface more generic. From Freddie Chopin (2014-8-28). * Kconfig, Makefile.unix, Makefile.win, syscall/Kconfig, arch/arm/src/armv6-m/svcall.h, up_svcall.c, armv7-m/svcall.h, and up_svcall.c: The system call library can now be built with CONFIG_NUTTX_KERNEL. New selection: CONFIG_LIB_SYSCALL (2014-8-28). * arch/arm/src/armv7-a/syscall.h: "Add an ARMv7-A system call definition header file (2014-8-28). * arch/arm/include/armv7-a/irq.h, arm_syscall.c, syscall/Kconfig, syscall_funclookup.c, syscall_nparms.c, and syscall_stublookup.c: ARMv7-A: Add SYSCALL handling logic (2014-8-28). * nuttx/fs/, drivers/, and sched/: Remove explicit references to errno. That is a problem from within the kernel for certain configurations (there are still more references to be fixed) (2014-8-28). * sched/clock/clock.h: In some configurations, g_system_tmer must be extern'ed as a private variable in the OS (2014-8-28). * include/errno.h and nuttx/clock.h: errno and g_system_timer must be handled in a special way if there are external modules (2014-8-28). * include/sys/syscall.h: System definitions should depend on CONFIG_LIB_SYSCALL not CONFIG_NUTTX_KERNEL (2014-8-28). * arch/arm/src/armv7-a: Rename syscall.h to svcall.h to work around some include path name collisions; fix some compilation errors in SYSCALL logic when debug is enabled (2014-8-29). * arch/arm/include/arm/syscall.h and armv7-a/syscall.h: Fix ARM7/9 and Cortex-A SYSCALLs: For threads in SVC mode, the SVC instructions clobbers R14. This must be taken account in the inline assembly (2014-8029). * arch/arm/src/armv7-a/arm_syscall.c: Fix hard coded values in dispatch_syscall() inline assembly. Back out/correct part of last change; that was going the wrong direction. With this change, the apps/examples/elf test works with address environments and call gates! (2014-8029). * Many, many files: Renamed CONFIG_NUTTX_KERNEL to CONFIG_BUILD_PROTECTED. Added configuration CONFIG_BUILD_KERNEL that will be used to generate a kernel (only) with full process support and will execute programs only from a file system. This new configuration is defined but only partially integrated (2014-8-29). * tools/refresh.sh: Add a tool to make refreshing configurations easier when you want to do a lot of them (2014-8-29). * tools/mksyscall.c: Build syscalls that do not need header files (there are none, however) (2014-8-30). * include/nuttx/errno.h syscall/syscall.csv and syscall_funclookup.c: Yet more issues with errno access via syscalls fixed (2014-8-30). * Makefile.unix, Makefile.win, Directories.mk, FlatLibs.mk, ProtectedLibs.mk, and KernelLibs.mk: Separate the common directory selection logic into Directories.mk; add support for kernel build. Move library selection logic in common *.mk files, one each for flat-, protected-, and kernel- mode builds (2014-8-30). * include/nuttx/syscall.h syscall/syscall.csv: clock_systimer needs the same fix as for get/set_errno when used with system calls (2014-8-30). * sched/Kconfig sched/init/os_bringup.c tools/cfgdefine.c: Add configuration options to start the system from a program on a file system (2014-8-30). * mm/ and include/nuttx/mm.h: Remove CONFIG_MM_MULTIHEAP. Non-multiheap operation is no longer supported (2014-8-31). * configs/sama5d4-ek/kernel: Add a configuration for testing the kernel build configuration (still a work in progress) (2014-8-31). * include/nuttx/arch.h, kmalloc.h, mm.h, sched/init/os_start.c, sched/sched_free.c, and arch/arm/src/sama5/sam_allocateheap.c: Clean up some kernel build heap allocation issues. The Cortex-A kernel build now compiles without errors (but cannot link until brk() and sbrk() are implemented) (2014-8-31). * mm/*mm_brkaddr.c, *mm_extend.c, Makefile, and include/nuttx/mm.h: Add low-level memory management hooks that will be needed to support brk() and sbrk() (2014-8-31). * Rename krealloc() to kmm_realloc() and kmemalign to kmm_memalign() for consistency with the rest of the naming (2014-8-31). * Rename kurealloc() to kumm_realloc(), kumemalign to kumm_memalign(), and kufree to kumm_free for consistency with the rest of the naming (2014-8-31). * Rename kumalloc() to kumm_malloc() and kuzalloc to kumm_zalloc() for consistency with the rest of the naming (2014-8-31). * Rename kmalloc() to kmm_malloc(), kzalloc() to kmm_zalloc(), and kfree() to kmm_free() and kuzalloc to kumm_zalloc() for consistency with the rest of the naming (2014-8-31). * mm/mm_sbrk.c, kmm_sbrk.c, umm_sbrk.c, and include/unistd.h: Initial implementation of sbrk() (2014-9-1). * arch/arm/src/armv7-a/arm_pgalloc.c, mm/umm_malloc.c, and mm_zalloc.c: Completes the implementation of sbrk() (untested) (2014-9-1). * configs/cc3200-launchpad: Updates to the CC3200-Launchpad configuration for better compatibility. From Jim Ewing (2014-9-1). * Removed all support from the 8051 from the NuttX source tree. The obsoleted code along with the removal patch can now be found at misc/Obsoleted/ (2014-9-1). * sched/sched/sched_releasetcb.c and task_setup.c, include/nuttx/arch.h and sched.h, and arch/*/*/*/Make.defs: There used to be two ways to pass parameters to new tasks, depending upon the configuration: Either (1) argv[] as created as an array with each string strdup'ed. Or (1) argv[] array and strings were created on the stack before the new task was started. Now, there is only one way, way (1). Way (2) might be slightly more compact, but this is not worth carry the complexity of two different ways of doing the same thing (2014-9-1). * sched/init/os_start.c: Fix error in initialize of IDLE TCB due to last change. The argument list is no long in the TCB, but in the stack. But not for the IDLE task. It needs its own mini-argv[] list so that it looks more like other threads (2014-9-1). * arch/arm/src/armv7-a/arm_addrenv.c, include/nuttx/addrenv.h, and mm/umm_*.c: Space at the beginning of the process data space is now reserved for user heap management structures. In the kernel build mode, these heap structures are shared between the kernel and use code in order to allocate user-specific data (2014-9-2). * include/unistd.h, nuttx/mm.h, and kmalloc.h, sched/init/os_start.c and sched/sched/sched_free.c, mm/kmm_sbrk.c and mm_sbrk.c, and arch/arm/src/sama5/sam_allocateheap.c: Restructuring of build to allow use of use-space allocators by kernel logic in the kernel build (2014-9-2). * arch/arm/include/armv7-a/irq.h, arm_syscall.c, crt0.c, include/nuttx/addrenv.h, and mm/umm_*.c: Add support for delivery of use-mode signals in the kernel build (2014-9-2). * mm/mm_graninit.c: Granule allocator initialization uses wrong allocator to setting aside kernel memory (2014-9-3). * sched/init/os_start.c: IDLE TCB setup needs to indicate that the IDLE thread is a privileged, kernel thread (2014-9-3). * include/nuttx/sched.h: Add a flag to group structure: If the group is created by a kernel thread, then all resources in the group must be privileged (2014-9-3). * sched/group/group_malloc.c, group_zalloc.c, group_free.c, group_create.c, group.h: Group creation logic must use new group flag when allocating resources so that the privileges on the resource are set correctly (2014-9-3). * sched/Kconfig and sched/init/os_bringup.c: Add capability to perform initial board initialization on a separate worker thread (2014-9-3). * tools/mkexport.sh: Fix 'make export'. Adding subdirectories to the sched/ directory broke the header file collection logic (2014-9-4). * Makefile.unix, Makefile.win, FlatLibs.mk, KernelLibs.mk, and ProtectedLibs.mk: In the kernel or protected builds, only the user libraries should be exported (2014-9-4). * Makefile.unix, Makefile.win, and tools/mkexport.sh: In 'make export', do not copy internal header files or build scripts if this is a kernel or protected build (014-9-4). * tools/mkexport.sh, arch/*/src/Makefile, arm/src/a1x/Make.defs, sama5/Make.defs, armv7-a/crt0.c: The 'make export' target needs to bundle up the user C startup file (crt0), not the kernel head object for the kernel and protected builds (2014-9-4). * tools/mkexport.sh: Add .config file to export package (2014-9-5). * configs/16z: Support for this board has been removed from the NuttX source tree (but still can be found in the misc/Obsoleted directory). This port is not ready for usage but may return to the NuttX tree at some point in the future (2014-9-5). * tools/Makefile.export and mkexport.sh: The apps/ import build requires that we extract more information from the platform Make.defs file (2014-9-5). * tools/Makefile.export and mkexport.sh: Need to export the setting of WINTOOL as well (2014-9-5). * SAMA5D4-EK kernel configuration now builds NSH instead of examples/elf (2014-9-6). * libc/pthread/pthread_attrinit.c, sched/pthread/pthread_create.c, and include/nuttx/pthread.h: Fix some conditional compilation in kernel build mode. And, while we are touching this logic, make g_default_pthread_attr const (2014-9-7). * arch/arm/src/armv7-a/arm_addrenv.c: Correct size comparison (pages vs. sections) (2014-9-7). * configs/sama5d4-ek/src/sam_bringup.c and sama5d4-ek.h: Need to call elf_initialize() on bring-up before attempting to load ELF modules (2014-9-7). * arch/arm/src/armv7-a/arm_addrenv.c: Fix loop counter... was overrunning a table on larger ELF files (2104-9-7). * arch/arm/src/sama5/sam_memories.c, sam_pgalloc.c, and sam_pgalloc.h: In kernel build with address environment, need logic to map user virtual addresses to physical addresses, and vice versa (2104-9-7). * SAM3X/Arduino Due: Fix typo in sam3x_periphclks.h; add SCLK definitions to board.h header file. From Fabien Comte (2014-9-8). * Several pthread interfaces: Add const storage class to to phthread parameters. From Freddie Chopin (2014-9-8). * libc/math: Corrected atan2 implementations from Denis Arnst (2014-9-8). * sama5d4-ek/knsh: Rename the kernel configuration to knsh to better match the naming used with other platforms (2014-9-8). * configs/cc3200-launchpad/README.txt: Add README file for the CC3200 Launchpad (2014-9-9). * configs/sama5d4-ek/README.txt, Kconfig, knsh/defconfig.ROMFS, src/sam_bringup.c, and sama5d4-ek.h: SAMA5D4-EK kernel config can now boot from a ROMFS file system (2014-9-9). * LibTargets.mk, Makefile.unix, and Makefile.win: Move common library targets out of Makefile.unix and Makefile.win into a new LibTargets.mk (2014-9-9). * LibTargets.mk and configs/sama5d4-ek/knsh/Make.defs: Add logic that will permit us to build user libraries with different CFLAGS than kernel code. This is needed because we need the -fno-common option when building ELF code to prevent SHN_COMMON relocations (2014-9-8). * binfmt/libelf/libelf_symbols.c, libelf_bind.c, and all implementations of up_relocate(): ELF relocations. Some relocation types do not have a named symbol associated with them. The design did not account for that case (2014-9-9). * binfmt/binfmt_execmodule.c: When allocating a stack for a new process using the user-space allocator, need to select the address environment first (2014-9-9). * arch/Kconfig, arm/src/armv7-a/pginline.h, arm_addrenv.c, and arm_pgalloc.c and include/nuttx/addrenv.h: Add configuration to use the fixed DRAM mapping for the page pool (if available) instead of remapping dynamically to access L2 page tables and page data. Also, add logic in address environment creation to initialize the shared data at the beginning of the .bss/.data process memory region (2014-9-10). * configs/sama5d4-ek/elf and knsh: These configurations now use the fixed DRAM mapping for manipulating the page memory pool (2014-9-10). * arch/arm/include/arch.h and src/armv7-a/arm_addrenv.c, nuttx/binfmt/binfmt_execmodule.c, libelf/libelf_addrenv.c, libelf_load.c, libnxflat/libnxflat_addrenv.c, include/nuttx/arch.h, and mm/umm_initialize.c: Add logic to initialize the per-process user heap when each user process is started (2014-9-10). * sched/clock/clock.h, clock_initialize.c, and clock_settime.c: Remove vestiges of g_tickbias; apply bias instead to g_basetime (2014-9-10). * include/nuttx/lib.h, sched/init/os_start.c, and configs/ea3131/locked/mklocked.sh: Replace the empty lib_initialize() function with a pre-processor macro (2014-9-11). * libc/misc/lib_stream.c: When a privileged thread exits, we have to use the kernel allocator to free memory; when an unprivileged thread exits, we don't have to do anything... heap memory will be cleaned up when the address environment is torn down (2014-9-11). * arch/arm/src/stm32/stm32_serial.c and chip/stm32f20xxx_rcc.h: Fix for UART7 and UART8 on STM32 clock enable from Aton (2014-9-11). * arch/arm/src/armv7-a/arm_vectors.S: ARMv7-A: Exception register save/restore needs to work a little differently if we support user mode processes (2014-9-11). * configs/cc3200-launchpad/src/cc3200_leds.c and other board files: Add LED support for the CC3200 Launchpad. From Jim Ewing (2014-9-11). * arch/arm/src/armv7-a/arm_initialstate.c: All tasks, even user mode tasks, must start in supervisor mode until they get past the start-up trampoline (2014-9-11). * arch/arm/src/armv7-a/arm_vectors.S: Fix logic for returning from exceptions to user-mode contexts. NuttX processes are now functional on the Cortex-A (2014-9-11). * arch/arm/src/armv7-a/arm_fullcontextrestore.S, arm_syscall.c, crt0.c, and svcall.h: Modify up_fullcontextrestore() for CONFIG_BUILD_KERNEL. It changed CPSR while in kernel. That will crash if the new CPSR is user mode while executing in kernel space. Fixed by adding a SYS_context_restore system call. There is an alternative, simpler modification to up_fullcontextrestore() that could have been done: It might have been possible to use the SPSR instead of the CPRSR and then do an exception return from up_fullcontextrestore(). That would be more efficient, but I never tried it (2014-9-12). * binfmt/libelf/libelf_load.c: ELF: Critical bugfix.. BSS was not being cleared (2014-9-12). * configs/sama5d4-ek/knsh/defconfig and defconfig.ROMFS: Enable NSH file applications in these configurations (2014-9-12). * libc/Kconfig, unistd/lib_execsymtab.c, configs/sim/nsh/defconfig, and stm32f4discovery/posix_spawn/defconfig: Having a symbol table is an option. There are no symbol tables with CONFIG_BUILD_KERNEL, for example (2014-9-12). * syscall/syscall.csv and include/sys/syscall.h: exevc, execvl, posix_spawn, and posix_spawnp were not properly integrated as system calls (2014-9-12). * syscall/syscall_lookup.h: Fix typos in the stub lookup table (2014-9-12). * configs/stm32f4discovery/netnsh, Kconfig, README.txt, and include/board.h: Add the network enabled NSH configuration for the STM32F4Discovery board with the STM32F4DIS-BB base board installed (2014-9-13). * nuttx/mm/umm_sbrk.c: Fix a typo in use of a configuration setting (2014-9-13). * configs/stm32f4discovery/README.txt: Add STM32F4DIS-BB GPIO pin usage (2014-9-13). * arch/Kconfig, arch/arm/include/arch.h, src/armv7-a/arm_addrenv.c, sama5/sam_pgalloc.c, and include/nuttx/addrenv.h: Add a configuration option for dynamic stack management (stack management not yet implemented) (2014-9-13). * arch/Kconfig arm/src/armv7-a/addrenv.h, arm_addrenv.c, and arm_addrenv_utils.c, a1x/Make.defs, and sama5/Make.defs, include/nuttx/addrenv.h and arch.h: Move static helper routines from arm_addrenv.c and may them global so that they can be shared by forthcoming stack address environment logic (2014-9-13). * arch/arm/src/armv7-a/arm_addrenv_stack.c, arm_addrenv.c, a1x/Make.defs, sama5/Make.defs, and include/nuttx/arch.h: Add logic needed to manage a virtualized stack. Not yet incorporated into base OS logic (2014-9-13). * sched/task/task_posixspawn.c: Kernel proxy thread should be a kernel thread, not a user task (2014-9-14). * include/sched.h and spawn.h, libc/Kconfig, spawn/Make.defs, lib_psa_getstacksize.c, lib_psa_init.c, and lib_psa_setstacksize.c, sched/task/Make.defs, task_create.c, and task_spawn.c: Don't build task_create() or task_spawn() interfaces if there is an address environment (2014-9-14). * arch/arm/src/armv7-a/arm_addrenv_ustack.c, include/nuttx/addrenv.h, arch.h, and other files: Rename everything associated with the dynamic process stack to ustack to make room in the name space for a kstack (2014-9-14). * arch/arm/src/armv7-a/arm_addrenv_kstack.c, include/nuttx/addrenv.h, arch.h, and other files: Add the initial implementation of the process kernel stack logic. Not yet integrated into the main OS logic nor tested (2014-9-14). * binfmt/binfmt_execsymtab.c and Makefile, sched/task/task_execv.c, task_posixspawn.c, and Make.defs, include/unistd.h, include/nuttx/binfmt/symtab.h, and libc/unistd/Make.defs: execv() is a basic system interface. It should not be in libc/ but rather in sched/task. Its symbol table helper logic also belongs in the kernel but belongs in binfmt/ with the other symbol table logic (2014-9-15). * include/sys/syscall.h, syscall/syscall.csv, syscall_lookup.h, and syscall_stublookup.c: execl() is not a system interface. It belongs in libc and should not have a system call associated with it (2014-9-15). * arch/arm/include/armv7-a/irq.h and src/armv7-a/arm_syscall.c: If we are configured to use a kernel stack while in SYSCALL handling, then we need to switch back to the user stack to deliver a signal (2014-9-15). * arch/arm/src/armv6-m/up_svcall.c, armv7-a/arm_syscall.c, and armv7-m/up_svcall.c: Fix a typo in system call when fetching parameter from the stack: regs[REG_PC]+4 is the address, not regs[REG_PC+4] (2014-9-15). * sched/sched/sched_releasetcb.c: Don't release user stack in kernel build. Already destroyed with all of the address environment (2014-9-15). * arch/arm/src/armv6-m/up_signal_dispatch.c, src/armv7-a/arm_signal_dispatch.c, and arch/arm/src/armv7-m/up_signal_dispatch.c: Move common/up_signal_dispatch.c to armv6-m, armv7-m, and armv7-a. The armv7-a version needs to be different to handle the case where we are dispatch kernel mode signals when running under a user mode group (2014-9-16). * arch/arm/src/armv7-a/arm_syscall.c: Correct stack handling if signal deliver to user processes (2014-9-16). * arch/arm/src/armv7-a/arm_physpgaddr.c, pgalloc.h, sama5/sam_pgalloc.c, and sam_pgalloc.h: Move some share-able logic from sama5/sam_pgalloc.c to armv7-a/arm_physpgaddr.c (2014-9-16). * arch/arm/src/sam34/sam_rtt.c: Only SAM4 family has RTTDIS bit in the MR register. SourceForge bug #33 from Fabien Comte (2014-9-17). * arch/arm/src/stm32/stm32_can.c: At the end of the interrupt handler, the interrupts were being disabled, if all packets have been transferred when the interrupt handler was invoked. This is problematic, because the interrupt handler calls can_txdone of the upper half which can enqueue new packets to send. Removed the block altogether, because can_txdone calls can_xmit which disables interrupts if there are no new packets to send. From Daniel Lazlo Sitzer (2014-9-17). * drivers/can.c: In can_txdone, waiters on the semaphore should be informed regardless of the return value of can_xmit. First it returns -EIO if there are no new packets, and second the information of the waiters is about the last transferred packet. From Daniel Lazlo Sitzer (2014-9-17). * SAMA5D4-EK: Add documentation/support for Rev E. board. Refresh NSH configuration. Fix some build errors/warnings introduced with recent work with the knsh configuration (2014-9-17). * arch/sim/Kconfig, src/up_spiflash.c, Makefile, up_initialize.c, and up_internal.h: Emulated SPI FLASH driver for the sim target from Ken Pettit (2014-9-19). * configs/stm32f4discovery/include/board.h, netnsh/defconfig, src/Makefile, stm32_sdio.c, stm32_boot.c, stm32_nsh.c, stm32_bringup.c, and stm32f4discovery.h: STM32F4Discovery: Add support for the microSD card slot on the STM32F4DIS-BB base board (2014-9-20). * Change all occurrences of NxConsole to NxTerm (2014-9-20). * include/sys/ipc.h, shm.h, mman.h, and types.h: Add shared memory definitions, types, prototypes (2014-9-22). * fs/smartfs/smartfs_smart.c: SMART FS update from Ken Pettit (2014-9-22). * mm/mm_gran/: Move granule allocator and page allocator from mm/. to mm/mm_gran/. (2014-9-22). * mm/kmm_heap/: Move kernel heap allocator from mm/. to mm/kmm_heap/. (2014-9-22). * mm/umm_heap/: Move user heap allocator from mm/. to mm/umm_heap/. (2014-9-22). * mm/mm_heap/: Move common heap logic from mm/. to mm/mm_heap/. (2014-9-22). * mm/shm/: Create a home for forthcoming shared memory logic (2014-9-22). * fs/procfs/fs_procfs.c: Fix some procfs breakage introduced by reorganizing some un-reorganizable data structures. From Ken Pettit (2014-9-22). * drivers/mtd/smart.c, fs/smartfs/smartfs.h, smartfs_procfs.c, and smartfs_utils.c, include/nuttx/fs/ioctl.h, and mtd/smart.h: Updated SMART FS procfs support. From Ken Pettit * configs/mikroe-stm32f4: Fix a few compile bugs and minor corrections to the mikroe-stm32f4 configuration source. From Ken Pettit (2014-9-22). * mm/Kconfig, shm/Make.defs, shmat.c, shmctl.c, shmdt.c, shmget.c, and Documentation/NuttxUserGuide.html: Add the documentation, build framework, and skeleton files for the shared memory feature (no logic yet provided) (2014-9-22). * include/sys/syscall.h, syscall/syscall.csv, syscall_lookup.h, and syscall_stublookup.c: Add system calls for shared memory interfaces (2014-9-22). * include/nuttx/shm.h, mm/shm/shm.h, and shm_initialize.c: Add shared memory initialization logic (2014-9-23). * include/nuttx/arch.h, Documentation/NuttxPortingGuide.html, and NuttxUserGuide.html: Add platform-specific interface definitions needed to support the shared memory feature (2014-9-23). * arch/arm/include/arch.h, src/armv7-a/addrenv.h, arm_addrenv.c, arm_addrenv_ustack.c, and arm_addrenv_utils.c: Add logic necessary to handle remapping of shared memory on context switches (2014-9-23). * include/nuttx/gran.h, mm/mm_gran/mm_granrelease.c, and Make.defs: Add interfaces to support un-initializing a granule allocator (2014-9-23). * arch/arm/src/armv7-a/arm_pgalloc.cm sched/group/group_addrenv.c, and other files: Fix some inconsistent field name in struct task_group_s: addrenv should be tg_addrenv (2014-9-23). * arch/arm/src/armv7-a/pgalloc.h: Extend virtual/physical address conversions to include addresses in shared memory (2014-9-23). * include/nuttx/shm.h, sched.h, mm/shm/shm_initialize.c, binfmt/binfmt_execmodule.c, sched/group/group_leave.c: Add support for a per-process virtual page allocator. This is a new member of the task_group_s structure. The allocator must be initialized when a new user process is started and uninitialize when the process group is finally destroyed. It is used by shmat() and shmdt() to pick the virtual address onto which to map the shared physical memory (2014-9-23). * mm/shm/shmat.c and shmdt.c: Completes the implementation of the core shared memory logic: shmget(), shmctl(), shmat(), and shmdt(). This is still some unfinished platform-specific code that needs to be done before we can begin testing (2014-9-23). * include/nuttx/mm: Move mm.h, gran.h, and shm.h from include/nuttx to include/nuttx/mm (2014-9-24). * arch/arm/src/stm32/stm32_can.c: STM32 CAN correction suggested by Max Holtzberg (2014-9-24). * arch/arm/src/armv7-a/addrenv.h, arm_addrenv_shm.c, arm_addrenv_utils.c, and pgalloc.h: This completes the implementation of shared memory support for the Cortex-A platforms (2014-9-24). * fs/fs_poll.c: Fix unnecessary delays and timing jitter in the implementation of poll(): No delay if timeout is zero; If timeout is greater than zero, first check if events are already pending events before starting the delay. From Johannes Hampel (2014-9-25). * drivers/mtd/at45db.c: In at45db_bwrite , the buffer is not increased when writing more than 1 page. Sourceforge bug #34 (2014-9-25). * crypto/cryptodev.c: Path segments reversed in include file path. Noted by Brennan Ashton (2014-9-25). * drivers/mtd/mtd_rwbuffer.c: The MTD Read-ahead/Write buffer layer appears to be functional (2014-9-25). * libc/stdio/lib_libdtoa.c: Change to lib_dtoa() to fix precision error from trailing zeroes. From Bob Doiron (2014-9-26) * fs/fs_poll.c: Re-implemented poll() delay using sem_timedwait() (2014-9-26). 7.6 2014-11-26 Gregory Nutt * fs/fs.h and other files: Rename fs/fs_internal.h to fs/fs.h (2014-9-28). * include/nuttx/semaphore.h and fs/fs.h: Add data structures that will allow us to move name semaphore support out of the OS and into the VFS (not complete) (2014-9-28). * fs/inode: Move inode and VFS utils from fs/. to fs/inode/. (2014-9-28). * fs/driver: Move driver logic from fs/. to fs/driver/. (2014-9-28). * fs/dirent: Move directory operations from fs/. to fs/dirent/. (2014-9-23). * fs/mount: Move mount-related files from fs/. to fs/mount/. (2014-9-23). * fs/vfs: Move renaming files in fs/. to fs/vfs/. (Don't all belong there) (2014-9-23). * fs/semaphore: Create a build structure that will (eventually) support using the VFS to manage named semaphores (2014-9-23). * configs/stm32f4discovery/include/board.h: STM32F4-Discovery: Fix some backward conditional compilation (2104-9-29). * nuttx/sched/init/os_start.c, semaphore/Make.defs, sem_initialize.c, and semaphore.h: Semaphore initialization is now only required if priority inheritance is enabled (2014-9-29). * fs/Makefile and mqueue/: Add build support for messages queues as part of the VFS (only build logic, no C files yet) (2014-9-29). * fs/inode/inode.h and fs/driver/driver.h: Move fs/fs.h to fs/inode/inode.h and some to fs/driver/driver.h (2014-9-29). * sched/task/task_vfork.c: Fix vfork(). Now that arguments are kept on the stack, the way that arguments are passed from parent to child in vfork() must change. This bug has always been present, but was not visible with the old strdup() way of passing arguments (2014-9-29). * arch/arm/src/common/up_vfork.c: Another vfork() problem: If we get to vfork() via system call, then we need to clone some system call information so that the return form the cloned system call works correctly (2014-9-29). * fs/mqueue: Move mq_open(), mq_close(), and mq_unlink() logic from sched/mqueue to fs/mqueue. Convert the logic so that it uses the VFS to managed the message queue namespace (instead of custom logic). By default, now message queues can be seen in /var/mqueue (2014-9-29). * arch/sim/src/up_simuart.c, up_uartwait.c: Removed old, strange up_stdio.c and implemented a simulated UART driver to provide the console input. Starts a separate, Linux domain pthread to read the console input in raw mode and provides the incoming data to NuttX via standard NuttX domain IPCs (2014-9-30). * arch/sim/src/up_setjmp32.S, up_setjmp64.S, Kconfig, Makefile, up_initialstate.c, up_internal.h, up_stackframe.c, and include/irq.h: Add support for 64-bit longjmp/setjmp in simulator platform. This will permit operation of the simulation natively on a 64-bit platform (2014-10-2). * include/fcntl.h: Implement create() as a macro (2014-10-4). * fs/vfs/Make.defs, fs_pread.c fs_pwrite.c, and include/unistd.h: Add pread() and pwrite() (2014-10-4). * include/sys/syscall.h syscall/syscall.csv, syscall_lookup.h, and syscall_stublookup.c: Add pread() and pwrite() system calls (2014-10-4). * include/aio.h: Add aio.h header file (2014-10-4). * libc/aio/lio_listio.c and Make.defs: Add empty skeleton file where lio_listio() will eventually be implemented (2014-10-4). * libc/Kconfig, aio/aio_read.c, aio_write.c, aio_return.c, aio_error.c aio.h, and Make.defs: Initial implementation of aio_read(), aio_write(), aio_return(), and aio_error() (2014-10-4). * include/signal.h and sched/Kconfig: Add definitions for SIGPOLL (2014-9-5). * libc/aio/aio_signal.c, Make.defs, and aio.h: Move AIO signal logic to a common location in aio_signal.c. Also fix several typos (2014-9-5). * libc/aio/aio_suspend.c, aio_cancel.c, aio_fsync.c, lio_listio.c and Make.defs: Initial implementation of aio_suspend(), aio_cancel(), lio_listio.c, and aio_fsync.c. This completes this implementation of the asynchronous I/O interfaces but there are still untested (2014-9-5). * fs/aio/Make.defs, aio.h, aio_cancel.c, aio_fsync.c, aio_read.c, aio_signal.c, and aio_write.c: Move all file operations from libc/aio to fs/aio. These will need to be kernel routines in order to handler issues with using file descriptors on worker thread (2014-10-5). * fs/aio/aio.h, Kconfig, aio_initialize.c, aioc_contain.c, Make.defs, and include/aio.h: Add a AIO control container to increase the payload with OS internal stuff (2014-10-6). * fs/aio/aio_cancel.c, aio_fsync.c, aio_read.c, aio_signal.c, and aio_write.c: Modify logic to use AIO control block container (2014-10-6). * fs/fs_initialize.c, Makefile, fs/inode/fs_inode.c, and inode.h: Modify FS initialization logic to handle AIO container initialization (2014-10-6). * Too many files to list: Major structuring of file system functions to better support asynchronous I/O. Repository should not be trusted until I have a chance to verify everything (2014-10-6). * include/nuttx/mm/mm.h: Fix a place in the memory manager where it explicitly assumed that the size of a pointer is 4 bytes. That is OK if the actual size is smaller but makes the heap unstable when used with the x86_64 host simulation (2014-10-6). * sched/wqueue, include/nuttx/wqueue.h, and libc/Kconfig sched/Makefile: Add support for priority inheritance on the low priority worker queue (2014-10-7). * sched/Makefile and sched/*/Make.defs: Simplify how C source files are selected in the build (2014-10-7). * fs/aio/aio_queue.c, Make.defs, aio.h, aio_fsync.c, aio_read.c, and aio_write.c: The asynch I/O implementation now satisfies POSIX priority requirements; it uses the new low priority worker thread interfaces to adjust the priority of the worker thread according to the priority of the client thread (2014-10-7). * arch/arm/src/stm32/chip/stm32_otghs.hstm32_otghs.c/h and chip/stm32_otghs.h: Add files that implement true high speed support for the STM32 OTGHS peripheral. From Brennan Ashton (2014-10-7). * arch/arm/src/stm32/ (several files): Integrates OTGHS support into the STM32; Eliminates the older OTGHS in FS mode logic. From Brennan Ashton (2014-10-7). * arch/arm/src/stm32/Kconfig, stm32_otgfsdev.c, chip/stm32f40xxx_pinmap.h, configs/stm32f429i-disco/ (several files): Remove non-functional vestiges of OTGHS in FS mode (including OTGFS2); try to convert the stm32f429i-disco configuration to use OTGHS instead of OTFHS in F mode (OTGFS2). But I don't have the boards and can't test (2014-10-7). * include/syslog.h, debug.h, libc/libc.csv, misc/lib_dbg.c, lib_dumpbuffer.c, stdio/lib_lowsyslog.c, lib_printf.c, lib_syslog.c, and fs/driver/fs_syslog.c: Make standard syslog and vsyslog POSIX compliant (also modify non-standard syslog functions for compatibility). This will break a lot of things until ALL usage of syslog is updated to use the modified interfaces (2014-10-8). * drivers/: Correct everything under nuttx/drivers, nuttx/arch, nuttx/net, nuttx/binfmt, and nuttx/configs to use the corrected syslog interfaces (2014-10-8). * libc/syslog and fs/syslog: Move syslog logic from libc/misc and libc/stdio to libc/syslog and fs/syslog. Also move some syslog logic from fs/driver to fs/syslog (2014-10-8). * fs/syslog/fs_syslogmask.c: Implement syslogmask() (2014-10-8). * include/sys/syscall.h, syscall/syscall.csv, syscall_lookup.h, and syscall_stublookup.c: Add syslog system calls (2014-10-8). * fs/Kconfig, syslog/fs_syslogenable, and include/syslog.h: Remove non-standard, conditional syslog_enable(), instead only the required, standard setlogmask() (2014-10-9). * arch/arm/src/stm32/chip/stm32_exti.h: Correct STM32 RTC EXTI bit definition. From Lazlo (2014-10-9). * include/syscall.h, syscall/, and libc/: Remove syslog interfaces from the set of system calls (2014-10-9). * libc/syslog: Move syslog back out of the kernel into the C libary (2014-10-9). * arch/mips/src/pic32mx/pic32mx-devcfg.h: For PIC32MX7, DEVCFG0 bit 2 must be set. Writing bit 2 as zero can brick the CPU on some versions. From Cris Kvist (2014-10-9). * sched/wqueue/, libc/wqueue, and include/nuttx/wqeueue.h: Separate kernel- and user-mode work queue logic. Decouple work queue data structures. This is part of the preparation to support multiple low-priority worker threads (2014-10-10). * include/nuttx/wqueue.h, libc/wqueue/Make.defs, work_usrthread.c, work_usrstart.c sched/init/os_bringup.c wqueue/kwork_hpthread.c, kwork_lpthread.c, and wqueue.h: Modularize starting of worker threads to better isolate individual initialization characteristics (2014-10-10). * arch/arm/src/ stm32_iwdg.c, stm32_wwdg.c, and chip/stm32_dbgmcu.h: Fix watchdog stop bit usage. From Lazlo (2014-10-10). * sched/wqueue/, libc/wqueue, and include/nuttx/wqueue.h: Add support for multiple low-priority worker threads. This is a necessary piece of the support for asynchronous I/O (2014-10-10). * sched/wqueue/work_inherit.c: Add logic for priority inheritance with multiple worker threads. How should this work? Tentatively, the all get reprioritized together. It would be best to just reprioritize the single thread doing the high priority work, but we don't know which that will be in advance (2014-10-10). * fs/aio/ and include/aio.h: Add support for socket-based transfers (2014-10-11). * arch/arm/include/stm32/chip.h, /src/stm32/Kconfig, and stm32_allocateheap.c: Support for the STM32 F411RE from Serg Podtynnyi (2014-10-14). * configs/Kconfig, README.txt, and nucleo-f401re: Extend this board configuration to also support the Nucleo-F411RE. From Serg Podtynnyi (2014-10-14). * tools/Config.mk: Add a PRELINK macro to Config.mk. From Kriegleder (2014-10-17). * arch/arm/src/efm32 and arch/arm/include/efm32: Add a basic port for the SiLabs EFM32 family.

From Marco Krahl (2014-10-20). * configs/stm32f429i-disco/Kconfig, src/ and lcd/: Add support for the STM32F429i Discovery's LCD. From Marco Krahl (2014-10-20). * arch/arm/src/lpc43xx/lpc43_gpioint.c, .h, lpc43_irq.c, and chip/lpc43_gpio.h: Fixes to allow compile of lpc43_gpioint.c. It likely doesn't work. From Brandon Warhurst (2014-10-21). * arch/arm/src/stm32/chip/stm32f103r_pinmap.h: Add ADC pinmap definitions for the STM32 F103R from Martin Lederhilger (2014-10-21). * arch/arm/src/armv7-m/up_itm.c and itm.h: Add CMSIS ITM header file and library.

From Brandon Warhurst (2014-10-23). * nuttx/arch/arm/src/lpc43xx/lpc43_rit.c, lpc43_rit.h, and related files: Add support for tickless operation using the NXP LPC43xx. From Brandon Warhurst (2014-10-23). * arch/arm/src/efm32/efm32_gpio.c and efm32_gpioirq.c: EFM32 port and pin decoding backward in every case. From Pierre-Noel Bouteville (2014-10-23). * arch/arm/src/armv7-m/up_itm_syslog.c: Correct file naming and fix compilation errors in up_itm_syslog.c. From Pierre-Noel Bouteville (2014-10-23). * configs/sam4e-ek/src/sam_ethernet.c (and other files):SAM4E-EK: Add support for PHY interrupt (2014-10-24). * include/wchar.h: Add a mostly bogus wchar.h header file. This file is mostly bogus because none of the wide character operations are currently supported in the Nuttx C library (2014-10-27). * include/termios.h, libc/termios/lib_isatty.c, and Make.defs: Add isatty() function. From Alan Carvalho de Assis (2014-10-27). * arch/arm/include/efm32, src/efm32, and configs/efm32-gxxx-stk: The EFM32 Gecko Starter Kit port is now functional. At least NSH is running over LEUART0 on the board (2014-10-29). * arch/arm/src/sam34/sam_serial.c and Kconfig: Add support for SAM3/4 basic TERMIOS and flow control. There are issues with IFLOW control: PDC or DMAC support is required (2014-10-29). * configs/sam4e-ek/src/sam4e-ek.h: Fix an error in a USART1 pin number (2014-10-29). * configs/efm32gg-stk3700: Board support for the SiLabs EFM32GG Giant Gecko Starter kit. Current with basic NSH configuration only. Testing is on hold until I receive hardware (2014-11-03). * libc/Kconfig: Move CONFIG_NSH_TMPDIR to CONFIG_LIBC_TMPDIR (2014-11-05). * libc/stdlib/lib_mkstemp.c, lib_mktemp.c, Make.defs and include/stdlib.h: Add mktemp() and mkstemp() (2014-11-05). * libc/stdio/lib_tempnam.c, lib_tmpnam.c, Kconfig, Make.defs and include/stdio.h: Add tmpnam() and tempnam() (2014-11-05). * drivers/rwbuffer.c: Fix typo that can cause compiler error (2014-11-05). * drivers/mtd/m25px.c: Extend MTD support to M25P16. From Sébastien Lorquet (2014-11-07). * arch/arm/src/stm32/Kconfig, chip.h, and include/stm32/chip.h: Support for the STM32F103RG. From Murilo Ponte (2014-11-10). * configs/stm32f100rc_generic: Removed this generic board configuration. I have decided to stop support of generic board configurations. Generic board configurations do not provide support for any specific hardware but can be useful only if there are not other examples for the setup for a particular architecture. Not the case here (2014-11-10). * include/nuttx/vt100.h: Add foreground and background color commands (2014-11-10). * sched/wdog/wd_create.c: Fix an important bug in the watchdog creation logic (2014-11-10). * include/unistd.h, libc/unistd/lib_access.c and Make.defs: From Lorenz Meier: The implementation of access() as vararg macro has the issue that any function call with the same name (even in a C++ class) will match with it and result in a compile error. I have replaced it with a small function, and tried to have decent documentation as well. This resolves the compile issue, and shouldn’t have negative side effects for users of the function (2014-11-11). * mm/mm_gran/mm_granrelease.c: If the INTR granule allocator mode is enabled, there is no semaphore to destroy. From Lorenz Meier (2014-11-12). * fs/nxffs/nxffs_dump.c: Fix problems with redefinitions of fdb macro. With the fix to the syslog prototype, a LOG priority must now be the first parameter. Fixed by replacing all occurrences of fdbg with syslog(LOG_DEBUG, and eliminating the macro redefinitions. Noted by Sebastien Lorquet (2014-11-12). * arch/arm/src/common/up_internal.h: Add protection from C++ name mangling in the ARM up_internal.h. From Lorenz Meier (2014-11-12). * include/nuttx/compiler.h: Defines inline functions as not instrumented - this is relevant for anyone using instrumentation. From Lorenz Meier (2014-11-12). * libc/string/lib_strncpy.c: The definition of strncpy() is that empty space should be zero-filled, the patch adds the zero filling (I didn’t know this, see e.g. the POSIX spec here: http://pubs.opengroup.org/onlinepubs/7908799/xsh/strncpy.html). From Lorenz Meier (2014-11-12). * arch/arm/include/limits.h: Remove the definition of INT_FAST32_MIN which is already defined in stdint.h (the correct location). From Lorenz Meier (2014-11-12). * arch/arm/src/efm32/efm32_clockconfig.c, configs/efm32gg-stk3700/README.txt and include/board.h: Fixes to get the EFM32GG-STK3700 basic NSH configuration running. It works! (2014-11-12). * drivers/bch/bchdev_driver.c: Add support for seeking in BCH. From Sébastien Lorquet. (2014-11-13). * sched/Kconfigs and configs/*/*/defconfig: Remove CONFIG_MAX_TASK_ARGS (2014-11-13). * binfmt/: Remove use of CONFIG_MAX_TASK_ARGS in exec() and unload_module() (2014-11-13). * libc/unistd: Remove use of CONFIG_MAX_TASK_ARGS in execl() (2014-11-13). * sched/: Remove some misc. usage of CONFIG_MAX_TASK_ARGS in task_start(), task_setup(), and vfork() (2014-11-13). * arch/arm/src/stm32/chip/stm32_otgfs.h: Correct a typo in the STM32 OTGFS register bit definitions (2014-11-13). * drivers/lcd/st7565.c/.h and include/nuttx/lcd/st7565.h: Add driver for ST7565 that works with NHD‐C12864KGZ display. From Pierre-noel Bouteville (2014-11-13). * net/route/net_router.c: I don't think that the net_route function has ever worked correctly. The source ip was updated in the match struct instead of the route ip. From Brennan Ashton (2014-11-14). * net/Kconfig arp/Make.defs, arp_send.c, and drivers/net/slip.c: ARP: Add support for the case where there are multiple networks: One being Ethernet and the other not. Suggested by Brennan Ashton (2014-11-14). * net/Kconfig, netdev/netdev_register.c, arp/arp_send.c, include/nuttx/net/net.h, netdev.h and several network drivers in arch/ and drivers/: Add a parameter to netdev_register() to indicate the link protocol supported by the driver. Use this value to replace some logic committed yesterday (2014-11-15). * configs/stm32f4discovery/netnsh/defconfig: Needs to set MAC address (2014-11-15). * arch/ and drivers/: Remove use of NET_LL_HDRLEN from Ethernet drivers. Use ETH_HDRLEN instead (2014-11-15). * net/arp/: Remove use of NET_LL_HDRLEN from net/arp logic. Use ETH_HDRLEN instead (2014-11-15). * net/ and include/nuttx/net: All network logic will now handle variable length link layer protocol headers within incoming packets. This permits use of multiple network interfaces with differing data links. For example, ETHERNET + SLIP (2014-11-15). * arch/arm/src/sam34/sam4s_periphclks.h: Add missing SPI0 clock configuration macro for the SAM4S. From spasbyspas (2014-11-16). * arch/arm/src/efm32/efm32_lowputc.c: EFM32 USART setup: Computation of BAUD includes shift; Eliminate additional shift. From Pierre-noel Bouteville (2014-11-16). * net/, include/, drivers/, arch/, various files: Rename CONFIG_NET_BUFSIZE to CONFIG_NET_ETH_MTU; Add CONFIG_NET_SLIP_MTU. Add data structures and logic to handle different MTUs when both Ethernet and SLIP are enabled (2014-11-16). * net/, include/, various files: Rename CONFIG_NET_RECEIVE_WINDOW to CONFIG_NET_ETH_TCP_RECVWNDO and CONFIG_NET_SLIP_TCP_RECVWNDO. Add data structures and logic to handler different TCP receive windows when both Ethernet and SLIP are enabled (2014-11-16). * configs/sama5d4-ek/bridge: Add a simple test for the dual EMACs on the SAMA5D4 (2014-11-17). * arch/arm/src/sama5/sam_emacb.c: Fix several typos that will prevent EMAC1 from initializing properly (2014-11-17). * include/nuttx/net/ip.h and tcp.h, net/icmp/icmp_send.c and igmp/igmp_send.c: Move IP header flags from tcp.h to ip.h and rename IP_FLAGS vs TCPFLAGS. The problem fixed here is that there IP flags were not available when TCP was disabled. The IP flags are used in ICMP and IGMP (2014-11-17). * sched/clock/clock_abstime2ticks.c: Calling mq_timedreceived() with immediate timeout was getting stuck and not timing out. Immediate timeout is achieved by setting absolute timeout value to past time, for example abstime={ .tv_sec=0, .tv_nsec=0 }. However absolute time was converted to relative time using unsigned integer arithmetic and resulted large ticks count by clock_abstime2ticks, instead of expected negative ticks value. Change corrects clock_abstime2ticks() to return negative ticks, if absolute time is in the past. From Jussi Kivilinna (2014-11-19). * fs/vfs/fs_poll.c: poll() was not waking up from signals (for example mq_notify() events). From Jussi Kivilinna (2014-11-19). * arch/arm/src/stm32/stm32_otghs.c, Make.defs, configs/stm32f429i-disco/src/stm32_usb.c and Makefile: STM32 F4 OTGHS device controller driver from Brennan Ashton (2014-11-20). * configs/sama5d3-xplained/bridge: Add a simple test for the EMAC and GMAC on the SAMA5D3 working together (2014-11-20). * libnx/nxtk/nxtk_drawframe.c: Remove warnings when CONFIG_NXTK_BORDERWIDTH is set to zero. From Pierre-Noel Bouteville (2014-11-20). * fs/vfs/fs_poll.c: Add proper handling for sem_timedwait errnos. From Jussi Kivilinna (2014-11-21). * net/udp/udp_conn.c and udp.h: Extensions to UDP "connection" structure for the case of multiple networks. In this case, assigned port numbers only have to be unique with respect to the IP address. So, for example, you could have multiple port 80's, one on each network (2014-11-21). * net/tcp/tcp_conn.c and tcp.h: Make tcp_listener static scope; it is not used outside of tcp_conn.c (2014-11-22). * net/udp/tcp_conn.c and tcp.h: Extensions to TCP connection structure for the case of multiple networks. See the description of the similar change for UDP above (2014-11-22). * net/route/net_router.c: Refuse to perform routing table lookups for the Broadcast IP address. From Brennan Ashton. * net/netdev/netdev_findbyaddr.c and netdev: Add logic to netdev_findbyaddr() to return the correct network device for the case where a broadcast address is used. This change caused trivial ripples through other files because additional parameters are required for netdev_findbyaddr() when CONFIG_NET_MULTINIC. Those other file include net/netdev/netdev_rxnotify.c, netdev_txnotify.c which, in turn, for changes to arp/arp_send.c, icmp/icmp_ping.c, socket/net_sendfile.c, recvfrom.c, sendto.c, tcp/tcp_send_buffered.c, and tcp_send_unbuffered.c (2014-11-23). * arch/arm/src/kl/chip/kl_i2c.h: I2C header file for the Freescale KL family. From Alan Carvalho de Assis (2014-11-23). * include/nuttx/fs/fs.h: Fix typo in conditional compilation. From Alan Carvalho de Assis (2014-11-23). 7.7 2015-01-26 Gregory Nutt * nuttx/drivers/eeprom and include/nuttx/eeprom/: Add support for generic EEPROM access via a character driver. Add also the EEPROM driver itself. From Sébastien Lorquet (2014-11-26). * libnx/nxfonts/nxfonts_pixel-lcd-machine.h and nxfonts_pixel-unicode.h, include/nuttx/nx/nxfonts.h, graphpics/Kconfig, and build-related files in libnx/nxfonts: Two new fonts from Pierre-noel Bouteville (2014-11-26). * configs/lpc4357-evb, arch/arm/src/pc43xx/chip/, configs/Kconfig, and and other related files: A port of NuttX to the LPC4357-EVB from Toby Duckworth. This port is a leverage of the LPC3330-Xplorer port and still have a some misinformation from that port that needs to be updated for the LPC4357-EVB (2014-11-26). * arch/arm/include/stm32/chip.h, src/stm32/Kconfig, chip.h, and chip/stm32f102_pinmap.h: Enable support for the STM32 F102. From https://github.com/PX4/NuttX/pull/28.diff (2014-11-27). * drivers/loop.c: Loop device should return -EINTR is interrupt by a signal (2014-11-27). * drivers/input/djoystick.c and include/nuttx/input/djoystick.h. Also drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add an interface definition and upper half driver for a discrete joystick device (2014-11-27). * arch/arm/src/efm32/Kconfig and efm32_serial.c: Add support for serial termios TCGET and TCSET. For the moment, only set/get speed is implemented. From Pierre-noel Bouteville (2014-11-27). * drivers/wireless/ and include/nuttx/wireless/cc3000.h: A set of 11 patches correcting issues with the CC3000 networking. All from Jussi Kivilinna (2014-11-28). Among these: 03/11: CC3000 driver was getting stuck at recv() when remote host closed connection and application tried to read data from remotely shutdown socket. This patch adds proper handling for remotely closed socket event. 07/11: Socket state initialization was done in 'register', while it should be initialized in 'open' and deinitialized in 'close'. Old way caused problems when device is closed, power-cycled and then reopened as old socket state was left enabled. 08/11: Select thread was getting stuck after 'close, power-cycle, reopen', since selectsem was not properly setup and cleaned up. 09/11: 'maxFD' was not properly reset in select worker and not checked for before calling cc3000_select(). 10/11: After wlan_stop()/cc3000_close(), irqsem was left with count '-1'. Therefore on next wlan_start()/cc3000_open(), initial value for irqsem was wrong. Additional repeated wlan_start()/wlan_stop() decreased irqsem value further. Obviously this causes driver not to function correctly and freeze. Patch moves initialization and destruction of waitsem, irqsem and readysem to cc3000_open/cc3000_close. * include/cxx/cctype: Undefine macros defined ctype.h so that builtin C++ implementations will be used intead. From Lorenz Meier (2014-11-28). * configs/stm3210e-eval/src/stm32_djoystick.c: Add a discrete Joystick supportfor the STM3210E-EVAL (2014-11-28). * drivers/input/djoystick.c include/nuttx/input/djoystick.h: Add a new ioctl to get the supported joystick discrete signals (2014-11-28). * drivers/input/ajoystick.c and include/nuttx/input/ajoystick.h. Also drivers/input/Kconfig and Make.defs, and include/nuttx/fs/ioctl.h: Add an interface definition and upper half driver for an analog joystick device. Initial check-in is only a little more of a clone of the discrete joystick driver and is as-of-yet untested (2014-11-27). * libc/Kconfig, misc/Make.defs, misc/lib_ioctl.c, fs/vfs/fs_ioctl.c, include/nuttx/fs/fs.h, include/sys/ioctl.h, syscall.h, and several files in syscall/: Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled (2014-11-29). * arch/arm/src/stm32/stm32_i2c.c: Port Tridge's I2C noise resilience logic from the PX4 repository (2014-11-29). * arch/arm/src/stm32/chip/stm32l15xxx_pinmap.h: Fix a typo in the MCO pin definition. From Jussi Kivilinna (2014-12-02). * arch/arm/src/stm32/stm32_rcc.h: Add missing MCO configuration for the STM32L1xxx. From Jussi Kivilinna (2014-12-02). * configs/sama5d3-xplained/src/sam_ajoystick.c: Add analog Joystick shield support for the SAMA5D3 Xplained board (2014-12-3). * configs/ucleo-f4x1re/src/sam_ajoystick.c and sam_adc.c: Add analog Joystick shield support for the Nucleo F4x1RE boards. There are still some ADC issues to be worke through as of the initial commit (2014-12-3). * /drivers/eeprom/spi_xx25xx.c and /include/nuttx/eeprom/spi_xx25xx.h: Add support for ST Micro EEPROM device geometries. From Sebastien Lorquet (2014-12-5). * sched/mqueue: msg type should be char * not void * in mq_send, mq_timedsend, mq_receive, and mq_timedreceive. Noted by Pierre-Noel Bouteville (2014-12-05). * fs/mqueue/mq_open.c and sched/mqueue/mq_msgqalloc.c: In message queue creation return ENOSPC error if size exceeds the configured size of pre-allocated messages; Use ENOSPC vs ENOMEM per OpenGroup.org. From Pierre-Noel Bouteville (2014-12-6). * Add sys/custom_file.h. Used when CUSTOM_FILE_IO is define and avoids re-definition errors about the FILE define. From Thomas Gruber via the PX4 repository (2014-12-06). * tools/bfd-converter.c and mkdeps.c: Eliminate a warnging about redefined strtok_r on some platforms (2014-12-8). * arch/sim/Kconfig: Allow building the simulated framebuffer driver even if NX is not enabled (12014-12-8). * configs/sim/traveler and README.txt: Add a configuration build and test the Traveler first person game using the simulator (2014-12-8). * arch/arm/src/stm32/chip/stm32f20xxx_pinmap.h and stm32f40xxx_pinmap.h: Set the GPIO_SPEED_50MHz on all F2 and F4 SPI pin configurations. This is based on an F411 SPI1 errata but the fixed is generalized to all SPI and all F2 and F4 (let me know if this introduces any other issues). Discovered and fixed by Sebastien Lorquet after much consternation (2014-12-8). * libc/stdio/lib_avsprintf.c: avsprintf(): Fix a bug in usage of va_list on x86. On x86, va_list is a pointer to a single copy on the stack. avsprintf() calls lib_vsprintf() twice and so traverses the va_list twice using va_start. va_start modifies that single copy on the stack so that the second call to lib_vsprintf() fails. This appears to be an issue with x86 only so far (2014-12-8). * stdint.h: Don't use hex values to specify minimum values of fixed width, signed values. Hex values are inherently unsigned and not usable for this purpose in all contexts (2014-12-8). * arch/arm/src/tiva/tiva_i2c.c, tiva_i2c.h, Kconfig, and Make.defs: Add build framework and skeleton files for Tiva I2C driver. Initial commit is just the STM32 I2C driver with name changes and STM32- specific logic removed (2014-12-9). * fs/procfs/fs_procfs.c: Add procfs write support. From Ken Pettit (2014-12-9). * include/crc8.h, libc/misc/lib_crc8.c, and Make.defs: Add CRC8 support. From Ken Pettit (2014-12-9). * drivers/mtd/smart.c, Kconfig, fs/smartfs/smartfs_smart.c, smartfs_procfs.c, smartfs_utils.c, smartfs.h, Kconfig, include/nuttx/fs/ioctl.h, smart.h, and mtd/smart.h: Implements wear- leveling in the SmartFS. From Ken Pettit (2014-12-9). * arch/arm/src/tiva/tiva_i2c.c: Driver is code complete but still untested (2014-12-10). * configs/tm4c123g-launchpad/src/tm4c_at24.c, tm4c_bringup.c, and other files: Add initialization logic for an external AT24 EEPROM. This is intended only to support testing of the Tiva I2C driver (2014-12-10). * libnx/Makefile, libnx/nxfonts/nxfonts_x11-misc-fixed-*.h, Make.defs, Makefile.sources, nxfonts_bitmaps.c, graphics/Kconfig, and include/nuttx/nx/nxfonts.h: Lots of fonts that derive from X11-misc-fixed-* fonts. Converted for use by NuttX by Pierre-Noel Bouteville (2014-12-10). * nuttx/drivers/mtd/m25px.c; M25P serial flash driver: Add subsector size of the M24P16 part. From Lazlo (2014-12-10). * libc/string/lib_strncpy.c: Commit d0c76ccacf0dc8988f9617ad82bf4349f456bb08 will trash a lot of memory if n == 0. From Yasuhiro Osaki (2014-12-11). * arch/arm/src/stm32/stm32_otghsdev.c. Fix for OTGHS device driver working in FS mode. From Ken Pettit (2014-12-12). * libc/stdio/lib_sscanf.c: Accept %X as well as %x as a format specifier. From Sébastien Lorquet (2014-12-12). * libc/stdio/lib_sscanf.c: Also accept %F as well as %f (2014-12-12). * arch/arm/src/stm32/stm32_otghsdev.c: For STM32 OTG HS DEV (in FS mode): Disable ULPI clock enable in RCC AHB1 Register. If Both ULPI and the FS clock enable bits are set in FS mode, then the ARM never awakens from WFI due to a chip issue. This is only an issue if you are using the internal PHY. From Ken Pettit (2014-12-13). * drivers/serial/serial.c: In case a thread is doing a blocking operation (e.g. read()) on a serial device, while it is being terminated by pthread_cancel(), then uart_close() gets called, but the semaphore (dev->recv.sem in the above example) is still blocked. This means that once the serial device is opened next time, data will arrive on the serial port (and driver interrupts handled as normal), but the received characters never arrive in the reader thread. The problem was fixed by re-initializing the semaphores on the last uart_close() on the device. From Harald Welte (2014-12-13). * sched/semaphore/sem_recover.c, Make.defs, seamphore.c, sched/wdog/wd_recover.c, Make.defs, wdog.h, sched/task/task_recover.c: Add logic to clean up after task_delete() or pthread_cancel() if the task happens to be waiting on a semaphore when it is cancelled (2014-12-13). * arch/arm/src/kl/kl_gpioirq.c, Kconfig, Make.defs, and kl_irq.c: Add GPIO interrupt capability for the KL architecture. The patch is almost the same as kinetis_pinirq.c, just minor modifications and rename kl_pinirq to kl_gpioirq to make it more generic to developers. From Alan Carvalho de Assis (2014-12-13). * arch/sim/src/up_ajoystick.c, Kconfig, Makefile, up_idle.c, up_internal.h, up_x11eventloop.c, up_x11framebuffer.c, configs/sim/src/Makefile, sim_boot.c, and traveler/defconfig: Add an X11 mouse-based simulation of an analog joystick device (2014-12-14). * drivers/sensors/adxl345*, include/nuttx/sensors/adxl345.h and other files: Add driver support for the ADXL345 accelerometer. From Alan Carvalho de Assis (2014-12-16). * configs/freedom-kl25z: Add board support for the ADXL345 accelerometer. From Alan Carvalho de Assis (2014-12-16). * Kconfig, include/debug.h, drivers/sensors/*, and Qencoder logic in arch/arm/src/stm32 and various QEncoder board support files under config/: Unify sensor debug. ADX driver was using input debug; LM75 and QENCODE that their own custom debug. Now all use CONFIG_DEBUG_SENSOR, sndbg() (2014-12-16). * configs/dk-tm4c129x: Initial board support for the Tiva DK-TM4C129x Connected Development Kit. The initial commit is just the Tiva TM4C123G-Launchpad board support with naming changes (2014-12-16). * include/nuttx/sched.h, sched/Kconfig, sched/init/os_start.c, sched/pthread/pthread_create.c, sched/task/task_prctl.c, sched/task/task_setup.c: strncpy() will not copy the terminating \0 into the destination if the source is larger than the size of the destination. Ensure that the last byte is always zero and let strncpy only copy CONFIG_TASK_NAME_SIZE bytes. The issue of unterminated names can be observed in ps when creating a pthread while CONFIG_TASK_NAME_SIZE is set to 8. From Daniel Willmann (2014-12-17). * configs/*/*/defconfig: The previous change increased the task name size allocation by one to hold a NUL terminator. This changes reduces the configured name size by one so that no additional memory is used (2014-12-17). * drivers/wireless/cc3000/cc3000.c: CC3000 Fix: Data can be unaligned. When dereferenced as an input ntosh(), a bad value is returned. Reported by Alan Carvalho de Assis (2014-12-18). * configs/freedom-kl25z: Update the Freedom KL25Z board CC3000 support to use the current CC300 interfaces. From Alan Carvalho de Assis (2014-12-18). * arch/arm/src/tiva, include/tiva, and many configurations: Change negative Tiva logic CONFIG_TIVA_DISABLE_GPIOx_IRQS to positive logic CONFIG_TIVA_GPIOx_IRQ (2014-12-18). * arch/arm/src/tiva/Kconfig: Fix configuration logic for IRQ interrupts. The various parts support varying numbers of GPIO blocks and with varying capabilities to support interrupts on the pins of different GPIO blocks (2014-12-18). * arch/arm/src/stm32/chip/stm32f40xxx_rcc.h: PLLSAI register name to this one in the reference manual. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/chip/stm32_ltdc.h: Rename CFBLR register name to the name used in the reference manual. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/chip/stm32_ltdc.h: Add missing clut register definition. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/stm32f40xxx_rcc.c: Configure PLLSAI clock to enable ltdc register access. From Marco Krahl (2014-12-19). * configs/stm32f429i-disco/include/board.h: Update board definition for the ili9341 LCD display. This configures all LCD settings for the RGB interface. Also adds a customer LCD display template. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/stm32_ltdc.h: Define a common layer description for the ltdc and dma2d controller. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/stm32_dma2d.c/.h and related files: Add infrastructure for dma2d support. From Marco Krahl (2014-12-19). * arch/arm/include/stm32/ltdc.h: Add interface to perform hardware accelerated layer operation. The following methods must be supported by the implementation: gevideoinfo, getplaneinfo, getlid, setclut, getclut, setcolor, getcolor, setcolorkey, getcolorkey, setalpha, getalpha, setblendmode, getblendmode, setarea, getarea, and update. And if DMA2D is supported: blit and blend. The method up_ltdcgetlayer provides access to a reference of a specific ltdc layer. From Marco Krahl (2014-12-19). * arch/arm/src/stm32/stm32_ltdc.c: Implements ltdc frambuffer support for the generic nuttx framebuffer interface, (see nuttx/video/fb.h). This also implements the interface to perform hardware accelerated layer operation by the ltdc controller and dma2d controller later (see nuttx/video/ltdc.h). The following methods are supported by the ltdc interface: getvideoinfo, getplaneinfo, getlid, setclut, getclut, setcolor, getcolor, setcolorkey, getcolorkey, setalpha, getalpha, setblendmode, getblendmode, setarea, getarea, and update. From Marco Krahl (2014-12-19). * include/nuttx/lcd/ili9341.h: Update interface control definitions. From Marco Krahl (2014-12-19). * configs/stm32f429i-disco/src/stm32_lcd.c: Add support for initializing ltdc framebuffer and the configured lcd display. This adds support for initializing of the ltdc controller and the lcd device connected on the stm32f429i-disco. The following methods are provided for the generic fb interface: up_fbinitialize, up_fbgetvplane, and up_fbuninitialize. The following methods are provided for the ltdc interface: up_ltdcgetlayer. From Marco Krahl (2014-12-19). * zrch/arm/src/stm32/Kconfig: Add configuration option for ltdc. This adds the following ltdc configuration options: dither support, cmap support, is this the right place for CONFIG_FB_CMAP?, support for extended ltdc interface. From Marco Krahl (2014-12-19). * nuttx/configs/stm32f429i-disco: Enable configuration of framebuffer support for the ltdc controller. From Marco Krahl (2014-12-19). * configs/stm32f429i-disco/src/stm32_boot.c: Initialize ltdc during bootup.

Add support for SSI2 and SSI3 (2014-12-21). * arch/arm/src/efm32/efm32_pwm.c/.h, efm32_timer.c/.h, and related build files: Add support for timer/PWM on the EFM32GG. From Pierre-noel Bouteville (2014-12-26). * drivers/serial/Kconfig, serial.c, serialirq.c, and include/nuttx/serial/serial.h: Add watermark levels to the serial RX flow control logic. Modify the rxflowcontrol method to accept the number of bytes in the buffer and a boolean indication of which watermark was crossed (2014-12-27). * sched/semaphore/sem_waitirq.c must be built when signals are disabled. That is because not handles not only the case of semaphore wait being awakened by a signal, but also the case with sem_timedwait.c when the semaphore wait is awakened by a timeout (2014-12-28). * arch/arm/src/stm32/stm32_ltdc.c: stm32: Fix faulty access to non- existing layer. This disables operation that requires double layer support, when configured for single layer only. From Marco Krahl (2014-12-29). * arch/arm/src/stm32/stm32_ltdc.c: stm32: Fix wait upon vertical blank. This should never have occurred before. From Marco Krahl (2014-12-29). * configs/stm32f429i-disco/ltdc/defconfig and src/stm32_boot.c: stm32f429i-disco: change ltdc initializing during boot up. This moves initializing of the ili9341 lcd and ltdc driver to the board specific initializing routine. From Marco Krahl (2014-12-29). * arch/arm/src/stm32/stm32_ltdc.c: Clean up documentation, some formatting improvements. From Marco Krahl (2014-12-29). * arch/arm/src/tiva/chip/tiva_ethernet.h, lm3s_ethernet.c, and tm4c_ethernet.h: Add logic to discriminate between LM3S class Ethernet register definitions and TM4C129X class Ethernet register definitions. Add TM4C129X Ethernet register definitions (2014-12-30). * arch/arm/src/tiva/tm4c_ethernet.c, lm3s_ethernet.c, Kconfig, and Make.defs: First cut at TM4C129X Ethernet driver. Initial commit is basically just the STM32 Ethernet driver with modifications for a clean compilation in the Tiva environment (2014-12-31). * arch/arm/src/stm32/stm32_rtc.c, stm32_rcc.c, Kconfig: Add support for the internal low speed clock (LSI) as a source of the RTC clock. Some boards do not have the external 32khz oscillator installed, for those boards we must fallback to the crummy internal RC clock. Turn on by defining CONFIG_RTC_LSICLOCK. From Kevin Hester (2015-01-02). * net/tcp/tcp_conn.c: Fix a logic error when CONFIG_NETDEV_MULTINIC is selected: net_unlock(flags) will be called will an uninitialized variable (2015-01-03). * arch/arm/src/tiva/tiva_irq.c: Fix Tiva IRQ control logic; was limited to only 64 IRQs. That is a problem for higher numbered IRQs on many platforms (2015-01-06). * arch/arm/src/stm32/stm32_sdio.c, drivers/mmcsd/mmcsd_sdio.c and Kconfig, and include/nuttx/sdio.h: MMCSD SDIO: Add support for a new SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop to poll the card R1 status to determine when the card was ready for the next transfer. That busy-wait can be quite long -- up to hundreds of milliseconds. An alternative is to look the SD D0 pin which will change state when the card is no longer busy. This change avoids the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, then waiting for the card to become ready without taking up CPU cycles. This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE and is currently only implemented for the STM32 SDIO driver. From David Sidrane (2015-01-08). * arch/arm/src/tiva/tiva_timerlib.c and .h: Add a timer library for generic support of Tiva timers (2015-01-08). * arch/arm/src/tiva/tiva_timerlow32.c: Add a driver lower half for drivers/timer.c. Only 32-bit periodic timers are supported. This provides userspace access to timers. * configs/px4-v2_upstream, Kconfig, README.txt: Remove the px4-v2_upstream configuration. Moved to misc/Obsoleted/configs. This was not the official configuration for the PX4 board and has led to confusion by NuttX users. The board configuration also requires some ongoing maintenance and customization to support ongoing PX4 testing and evaluation. It is best retained the PX4 repositories where it can be properly maintained and not in the upstream NuttX repository (2015-01-14). * net/netdev/netdev_ioctl.c and include/nuttx/net/ioctl.h: Add support for IPv6 ioctls to manipulate IP addresses (2015-01-14). * net/icmpv6: Create a future home for ICMPv6 (2015-01-14). * net/icmp: Remove all logic conditioned on CONFIG_NET_IPv6 (2015-01-14). * net/, include/nuttx/net, and a few other files: (1) Copied all ICMP sources files to net/icmpv6 with proper renaming and removal of IPv4 logic, (2) remove IPv6 logic from files in net/icmp, (3) copied include/nuttx/icmp.h to icmpv6.h and removed IPv4 specific logic, (4) removed all IPv6 logic from icmp.h, (5) IP_HDRLEN became IPv4_HDRLEN and IPv6_HDRLEN, (6) ip_chksum() became ipv4_chksum() and ipv6_chksum(), and (7) added partial support for ICMPv6 statistics (2015-01-14). * arch/, drivers/net/, include/nuttx/net, and net/devif: (1) Rename devif_input() ipv4_input(), (2) copy net/devif/devif_input.c to ipv6_input.c, remove all IPv4-specific logic, (3) rename net/devif/devif_input.c to ipv4_input.c, remove all IPv6-specific logic, and (4) xplit IPv4 header structure out as net_ipv4hdr_s from net_iphdr_s (2015-01-15). * arch/ and drivers/net: All Ethernet drivers: Call ipv6_input() if IPv6 is enabled and an IPv6 packet is received (2015-01-15). * net/devif, net/tcp, net/ucp, include/nuttx/net: Separate tcp_input() and udp_input() into separate functions tcp_ipv4_input(), tcp_ipv6_input(), udp_ipv4_input(), and upd_ipv6_input() than can deal will the data offsets caused by the differing sizes of the IP header (2015-01-15). * net/utils/net_ipv6_maskcmp.c: Add missing implementation of net_ipv6_maskcmp() (2015-01-15). * Networking: Drivers can have both IPv4 and IPv6 addresses, but a socket can only only one or the other; The socket connection structures need to include a union of IPv4 and IPv6 addresses for the local address binding and for the remote address connections (2015-01-16). * Networking: Replace all references to net_ipaddr_t with either in_addr_t on net_ipv6addr_t. The goal is to support both IPv4 and IPv6 simultaneously. This requires that the two types be distinct and not conditionally typedef'ed to net_ipaddr_t (2015-01-16). * Networking: Replace all references to the macros net_ipaddr_copy, net_ipaddr_hdrcopy, net_ipaddr_cmp, net_ipaddr_hdrcmp, and net_ipaddr_maskcmp with the appropriate IPv4 or IPv6 version of the macro (such as net_ipv4addr_copy). The goal is to support both IPv4 and IPv6 simultaneously. This requires that the macros be distinct and not conditionally defined to one on or the other (2015-01-16). * Networking: UDP and TCP MSS depends on the IP header size (as well as the link layer header size) and cannot be represented with a single value (2015-01-16). * net/neighbor: Move net/ipv6 to net/neighbor (2015-01-16). * include/net/if.h: Add a bit to the device flags to indicate if the device packet buffer holds an IPv4 or an IPv6 domain packet. Set/clear the flag along with the correct offset to the application payload data as each packet is received (2015-01-17). * net/socket, net/tcp, net/udp: Add logic to select the domain of the outgoing packet before sending any UDP or TCP packet. This sets the bit to indicate the IPv4 or IPv6 domain and the correct offset to the output going payload data (2015-01-17). * net/socket and net/tcp: When we are ready to receive data or when we have outgoing data ready to be sent, we need to the notify the appropriate device driver of this condition. The notifying socket will be configured as either PF_INET or PF_INET6 and must look up the correct driver using the correct IP domain (2015-01-17). * net/socket/accept.c: Fix accept() so that it returns the correct IP address for the selected socket IP domain (2015-01-17). * Networking: Final detangling off IPv4 and IPv6 TCP/UDP send logic. The networking subsystem now compiles with IPv6 enabled (2015-01-18). * arch/arm/src/tiva/tm4c_ethernet.c: When calling into the stack from the worker thread, it is necessary to have the stack locked (2015-01-18). * nuttx/arch/arm/src/stm32/stm32_serial.c: Fix declaration and definition of up_receive() and up_dma_receive() to match fields of uart_ops_s from nuttx/include/nuttx/serial/serial.h. From Freddie Chopin (2015-01-19). * drivers/pipes/pipe.c, drivers/usbdev/cdcacm.c, and mm/mm_gran/mm_granalloc.c: Fixes some issues found by the PX4 team using Coverity. From Pavel Krienko (2015-01-19). * net/icmpv6/icmpv6_solicit.c, net/neighbor/neighbor_out.c, and other files: Add logic to search the Neighbor Table and update the destination address in the output Ethernet header OR to send an ICMPv6 Neighbor Solicitation if there is no entry in the Neighbor table for the IPv6 address (2015-01-20). * arch/ and drivers/net: Add missing raw/packet socket support to all Ethernet driverss (2015-01-20). * arch/ and drivers/net: Networking: Modify all Ethernet drivers: Do neighbor look-up on all outgoing IPv6 packs in order to properly set the destination link layer address (2015-01-20). * Networking: When sending ICMPv6 advertisements and solicitations, set the NOARP bit so that we don't overwrite the destination MAC address (2015-01-20). * Many files: Correct name of fields in struct sockaddr_in6: sin6_port and sin6_family, not sin_port and sin_family (2015-01-20). * net/socket/accept.c: Correct the value returned by accept() in the case where net_lockingwait() is called. It was returning -1 and losing the errno value. Noted by Rony Xln (2015-01-22). * net/: After some significant effort, ICMPv6 and TCP are both functional when IPv6 is selected. UDP still requires testing (2015-01-22). * configs/dk-tm4c129x/ipv6: Add an IPv6-enabled NSH configuration (2015-01-23) * include/nuttx/net/icmpv6.h and net/icmpv6/icmpv6_ping.c: First cut at ICMPv6 ping logic. It works in both directions! (2015-01-23). * arch/arm/src/efm32/efm32_rmu.c and .h: Add support for the EFM32 reset management unit (RMU). From Pierre-noel Bouteville (2015-01-23). * include/nuttx/math.h: Adds support for the expm1 functions: http://pubs.opengroup.org/onlinepubs/009695399/functions/expm1.html. From Brennan Ashton (2015-01-23). * Many file: Add CONFIG_STACK_COLORATION that does the same thing as CONFIG_DEBUG_STACK but without enabling debug. From David Sidrane (2015-01-24). * Remove CONFIG_DEBUG_STACK. Adding CONFIG_STACK_COLORATION makes this configuration option pointless (2015-01-24). * net/: Clean up network status collection for IPv6 (2015-01-24). * arch/ and configs/: Changes to get USART 2 & 3 working on lpc4357-evb. These changes are required to get USART 2 and 3 working on the Embest development board. From Toby Duckworth. 7.8 2015-02-11 Gregory Nutt * include/nuttx/math.h and libc/math: Add support for inverse hyperbolic functions. From Brennan Ashton (2015-01-26). * include/nuttx/math.h: Add math library definition for isfinite(). From Brennan Ashton (2015-01-26). * include/nuttx/math.h and libc/math/lib_erf*.c: Add error function to math library. From Brennan Ashton (2015-01-26). * include/nuttx/math.h and libc/math: Add math library defines for nan(), copysign(), and trunc() functions. From Brennan Ashton (2015-01-26). * sched/wqueue/kwork_process and libc/wqueue/lib_usrthread.c: Fix a backward calculation when determining the time to the next event. This is a bug in the back-up, "fail safe", work queue timing so it not as bad as it seems. From Liio Chen via the PX4 repository (2015-01-27). * arch/arm/src/stm32/stm32_exti_gpio.c: Disabling any of EXTI 5-9 interrupts was disabling interrupts for all EXTI 5-9. Same issue with EXTI 10-15. From Jussi Kivilinna (2015-01-27). * arch/arm/src/stm32/stm32_rtcc.c and Kconfig: Recent changes to stm32_rtcc.c do not compile with STM32L15XX configurations. From Jussi Kivilinna (2015-01-27). * net/local: Add initial support for local, Unix domain sockets. Initial support is limited to SOCK_STREAM and is untested on initial commit (2014-01-27). * net/iob, net/tcp/tcp_callback.c, and include/nuttx/net/iob.h: There were issues with the TCP write-ahead buffering if CONFIG_NET_NOINTS was enabled: There is a possibility of deadlocks in certain timing conditions. I have not seen this with the Tiva driver that I have been users but other people claim to see the issue on other platforms. Certainly it is a logic error: The network should never wait for TCP read-ahead buffering space to be available. It should drop the packets immediately. This was fixed by duplicating most of the IOB interfaces: The versions that waited are still present (like iob_alloc()), but now there are non-waiting versions of the same interfaces (like iob_tryalloc()). The TCP read-ahead logic now uses only these non- waiting interfaces (2015-01-27). * net/tcp/tcp_send_buffered.c and tcp_wrbuffer.c: Fix another deadlock condition. tcp_write_buffer_alloc() calls sem_wait() with network locked. That worked if CONFIG_NET_NOINTS was not defined because interrupts are automatically restored when the wait happens. But with CONFIG_NET_NOINTS=y, the wait blocks with the network locked -- bad style and also can lead to a deadlock condition (2015-01-28). * arch/arm/src/armv7-a/arm_memcpy.S and arch/arm/src/armv7-m/up_memcpy.S: ARM assembly language memcpy.S's were not returning a value in R0 they are required to do. From David Sidrane (2015-01-29). * net/local: Extend Unix domain socket support to include support for datagram Unix domain sockets (2015-01-29). * net/socket/accept.c: Fix a major TCP bug introduced with commit e71c09ce9777ff732cb60bd07fb43d85522f79d6. Some connection logic was reordered; setting the socket as 'connected' got moved to BEFORE the point where the check was made if the socket was already connected. The resulting behavior was odd: Telnet would connect, but then when you exit and reconnect, it would fail to connect. But then if try again, it would connect okay. So the symptom was connect-fail-connect-fail-... (2015-01-29). * net/socket/net_poll.c, recvfrom.c, and udp/udp_callback.c: Add UDP read-ahead support. This enables support for for poll/select on UDP sockets and also non-blocking UDP sockets. From Macs N (2015-01-30). * net/local/local_netpoll.c, socket/net_poll.c, and udp/udp_netpoll.c: Separate out UDP poll logic from net_poll.c into a new udp_netpoll.c; Create a skeleton local_netpoll (2015-01-30). * net/socket/net_poll.c and tcp/tcp_netpoll.c: Separate TCP poll logic out of net_poll.c and move it into the new tcp_netpoll.c (2015-01-30). * arch/arm/src/efm32/efm32_clockconfig.c: Logic to unconditionally enable LE clocking. Even you don't use core clock LE as source for LFA or LFB, to read are write any register not clocked by HFPERCLK or HFCORECLK, HFCORECLKLE should be enabled. From Pierre-noel Bouteville (2015-01-30). * drivers/net/slip.c: SLIP interface improvements. From Macs N (2015-01-30). * clock_systimespec(): Fixes for compilation errors in certain configurations. From Macs N. * drivers/pipes/fifo.c, include/nuttx/fs/ioctl.h, and net/local/local_fifo.c: Fix a race condition between FIFO buffer operations and the opening and closing of FIFOs which necessary when the FIFOs are used to support Unix domain, datagram sockets. The default policy is the deallocate FIFO buffering when the last client closes the pipe. When when used for datagram communications, packets left in the FIFO will be lost. Some like UDP read-ahead is needed: The buffered data in the FIFO needs to be retained until the reader gets a chance to re-open the FIFO. Added an ioctl (PIPEIOC_POLICY) to control the buffer policy. Default (0) is the legacy behavior; Unix domain datagram logic sets the alternative policy so that the packet data persists after the FIFO is closed (2015-01-30). * net/local: Add configuration options so that Unix domain stream and datagram support can be separately enabled (2015-01-31). * fs/vfs/fs_unlink.c and include/nuttx/fs/fs.h: Add an unlink method to both the character and block driver interface. This is important because if the driver inode is unlinked and there are no open references to the driver, then the driver resources will be stranded. On the unlink call, the driver has the opportunity (1) check if there an any open references, and if not, (2) free the driver resources (2015-01-31). * drivers/pipes: Implement the unlink method. If the pipe/FIFO is unlinked, it will marked the pipe/FIFO as unlinked. If/when all open references to the driver are closed, all of the driver resources will be freed (2015-01-31). * arch/avr: Added architecture support for the Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum (2015-01-31). * configs/moteino-mega: Added support for the LowPowerLab MoteinoMEGA that is based on the Atmel AVR ATMega1284P MCU. From Jedi Tek'Unum (2015-01-31). * EFM32 RTC: RTC driver using BURTC. From Pierre-Noel Bouteville (2015-02-01). * drivers/ramdisk.c, include/nuttx/fs/ramdisk.h, and other files: Add logic to dispose of the driver and RAM buffer when the RAM disk has been unlinked and all open references to the RAM disk have been closed. Add new parameters to romdisk() to specify what should be done with the RAM/ROM buffer -- Should it be freed or not? Changed all calls to ramdisk() to use these new parameters (2015-02-01). * net/icmpv6/icmpv6_neighbor.c, icmpv6_notify.c (and other files): Adds basic logic to support verification that we have the IPv6 address in the Neighbor Table. This feature is important because otherwise the first packet sent to a remote peer will fail (it will be replaced with a Neighbor Solicitation) (2015-01-02). * net/arp/arp.h, arp_notify.c, and arp_send.c: Fixes another CONFIG_NET_NOINTS issues. When called sem_timedwait() with the network locked, the network stays locked while we wait which is not what we want (without CONFIG_NET_NOINTS, interrupts are re-enabled while we wait and all is well) (2015-02-02). * net/icmpv6/icmpv6.h, icmpv6_neighbor.c, icmpv6_notify.c: Apply the same fix as for ARP to the Neighbor Solicitation logic (2015-02-02). * sched/sched/sched_timerexpiration.c, Kconfig, and include/nuttx/arch.h: On my platform I have just 16-bit timer clocked at 32kHz. As result oneshot timer max delay is 2s. The patch adds limit of maximum ticks in sched_timer_start(). From Macs N (2015-02-03). * arch/arm/src/sam34: Add support for Tickless mode of operation for the SAM4CM platform. From Macs N (2015-02-03). * include/nuttx/net/icmpv6.h and net/icmpv6/Kconfig: Add support for sending ICMPv6 Router Solicitation and receiving Router advertisement. This is a part of the ICMPv6 auto-configuration logic is still not complete (2015-02-03). * libnx/nxfonts/nxfonts_getfont.c and nxfonts_sans39x48.h: Fixes a problem with one of the font files. From Pierre-noel Bouteville (2015-02-03). * arch/arm/src/efm32/efm32_rtc_burtc.c: Remove a misbehaving assertion. From Pierre-noel Bouteville (2015-02-03). * net/icmpv6: Implemented the ICMPv6 Autonomous Auto-Configuration logic. This is an IPv6 alternative to DHCP. It obtains the IPv6 addresses and masks using ICMPv6 Router Solicitation and Advertisement messages (2015-02-03). * arch/arm/src/stm32/stm32_aes.c, stm32_aes.h, and chip/stm32l15xxx_aes.h: Add driver for STM32L162XX AES peripheral. From Juha Niskanen (2015-02-04). * net/icmpv6/icmpv6_radvertise.c, Kconfig, and other files: Add option to send Router Advertisement Messages (2015-02-05). * net/icmpv6/icmpv6_input.c, arch/arm/src/tiva/tm4c_ethernet.c, and stm32/stm32_eth.c: Add logic to behave like a router (if so configured): NuttX will not send the router advertisement message in response to any router solicitation messages (2015-02-05). * configs/stm32f4discovery/ipv6 and arch/arm/src/stm32/stm32_eth.c: Add an IPv6 configuration for the STM32F4-Discovery board (with the STM32-DISCO_BB base board). Verify that the STM32 Ethernet driver works with IPv6 (2015-02-05). * net/icmpv6/icmpv6_input.c and icmpv6_rnotify.c: With these two changes both ICMPv6 autonomous autoconfiguration and router functionality appear to be working with no problems (2015-02-05). * arch/arm/src/tiva and configs/tm4c123g-launchpad: Adds support for TM4C123G timers; integrates with the TM4C123G Launchpad. From Calvin Maguranis (2015-02-05). * arc/arc/src/tiva/tiva_adc.c and .h: Adds a Tiva ADC driver. From Calvin Maguranis (2015-02-05). * tmv4c123g-launchpad: Add Tiva ADC support to the TM4C123G-Launchpad. From Calvin Maguranis (2015-02-05). * arch/arm/src/stm32/stm32_spi.c: The source clock for SPI 4,5, and 6 should be PCLK2, not PCLK1 (for F411, F427, and F429). Per David Sidrane (2015-02-07). * drivers/syslog/syslog_console.c, include/nuttx/syslog/syslog_console.h, and the console device initialization logic for all architectures: Add an option to use the syslog'ing device as the system console. This option enables a low-level, write-only console device at /dev/console (similar to the low-level UART console device). From Pierre-noel Bouteville (2015-02-08). * net/utils: Clean up and consolidate some clunky stuff in ARP and ICMPv6 time waiting logic by adding new net_timedwait() function (2015-4-09). * arch/arm/src/stm32/stm32_eth.c: Add logic so that STM32 Ethernet driver can avoid interrupt level processing and, instead, execute on the work thread (2015-4-09). * configs/stm32f4discovery/netnsh and ipv6: Convert all STM32F4- Discovery configurations (with base board) to configure the Ethernet driver to use the work queue (vs. interrupt level processing) (2015-4-09). * libc/unisted/lib_execl.c: Fix bad logic in counting the number of arguments. This could never have worked. Noted by Pierre-noel Bouteville (2015-4-09). * arch/arm/src/sama5/sam_emacb.c: Add support for Multicast address matching and IPv6 in the SAMA5D4 Ethernet driver (2015-02-09). * configs/sama5d4-ek/ipv6: Add a configuration for testing IPv6 with the SAMA5D4-EK (2015-02-09). * arch/arm/src/armv7-a/arm_doirq.c: ARMv7-A interrupt handler should not automatically re-enable interrupts on interrupt return. That interferes with the driver's ability to manage interrupts (2015-02-09). * arch/arm/src/sama5/sam_emacb.c: Add support for CONFIG_NET_NOINTS in the SAMA5D4 Ethernet driver so that the driver can operate from the work queue thread instead of doing everything from the interrupt level (2015-02-09). * SAMA5D4-EK: CONFIG_NET_NOINTS is now enabled in the nsh and ipv6 configurations (2015-02-09). * arch/arm/src/a1x, arm, c5471, common, dm320, imx, lpc2378, lpc31xx, sama5, str71x, hc/src.common, sh/src/common, x86/src/common, z16/src/common, z16f, z80/src/z8: Big, very risky change: Remove all occurrences of up_maskack_irq() that disable and enable interrupts with up_ack_irq() that only acknowledges the interrupts. This is only used in interrupt decoding logic. Also remove the logic that unconditionally re-enables interrupts with the interrupt exits. This interferes with the drivers ability to control the interrupt state. This is a necessary, sweeping, global change and unfortunately to test (2015-02-09). * mtd/ramtron.c: Table of parts is not terminated properly if CONFIG_RAMTRON_FRAM_NON_JEDEC is not defined. Noted by David Sidrane (2015-02-09). * arch/arm/src/sam34/sam_emac.c, sama5/sam_emaca.c, and sama5/sam_gmac.c: Clone the SAMA5D4 IPv6 support to the SAM4E EMAC and SAMAd3 EMAC and GMAC drivers (2015-02-09). * net/: Lots of build problems introduced into multiple NIC support. Many places where conditional logic based on CONFIG_NETDEV_MULTINIC is confused with CONFIG_NET_MULTILINK. Lots of code changed with IPv6 that was never compiled with MULTINIC enabled. Still some problem with parameter passing in the MULTINIC configuration(2015-02-09). * net/iob/Kconfig: In IOB Configuration, the default number of IOB chains must be more than zero is UDP read-ahead is enabled (2015-02-10). * net/tcp/tcp_conn.c and udp/udp_conn.c: Fix several build errors/warning with IPv4 + IPv6 + multiple networks are enabled (2015-02-10). * arch/arm/src/sam34/sam_emac.c: SAM4 Ethernet driver bow supports operation using the high priority work queue so that packet processing can occur outside of interrupt level processing (2015-02-10). * SAM4E-EK: The nsh configuration now configures the Ethernet driver for execution on the HP work thread (2015-02-10). * arch/arm/src/lpc17xx/lpc17_ethernet.c: Add IPv6 support to the LPC17 Ethernet driver. Untested... I no longer have a proper environment for LPC17 debug (2015-02-10). * include/netinet/in.h and libc/net/lib_addrconfig.c: Some extensions to netinet/in.h adding some Linux compatible definitions. From Macs N (2015-02-11). * arch/arm/src/kl: Add architectural support for the K26Z128VLH4 chip. From Derek B. Noonburg (2015-02-11). * configs/freedom-kl26z: Add board support for the Freedom KL26Z board. From Derek B. Noonburg (2015-02-11). 7.9 2015-04-14 Gregory Nutt * arch/arm/src/tiva: Add support for the TM4C1294. Contributed by Frank Sautter (2015-02-11). * configs/tm4c1294-launchpad: Add support for the TM4C1294 Launchpad. Contributed by Frank Sautter (2015-02-11). * gettimeofday(): Move gettimeofdady() from sched/clock to libc/time. Remove gettimeofday() from NuttX system calls. It is only a wrapper around clock_settime() and does not need a trap. gettimeofday() is no longer treated as a core OS interface (2015-02-12). * settimeofday(): gettimeofday has been decrecated in POSIX 2008. settimeofday() was never part of POSIX, but I decided to add it to libc as well just for symmetry (2015-02-12). * drivers/sensors/mpl115a.c and include/nuttx/sensors/mpl115a.h: Add driver for the Feescale MPL115A baramoter. From Alan Carvalho de Assis (2015-02-12). * configs/viewtool-stm32f107: Add support for an optional, add-on Freescale MPL115A baramoter. From Alan Carvalho de Assis (2015-02-12). * sched/clock/clock_systimer.c: Fix a problem in clock_systimer64 that occurs when (1) the 64-bit system time is enabled, and (2) the value of CONFIG_USEC_PER_TICK is less than 1 milliseconds (such as when using the tickless mode of operation). In that case, the conversion of time to 64-bit millisecond value in clock_systmer64() causes some bad times to be returned. Time was converted to milliseconds, then to configured ticks. Precision was lost in the millisecond conversion. The fix is to first convert time to a 64-bit microsecond value, then to the configured tick value. Noted by David Sidrane (2015-02-13). * include/nuttx/rtc.h, arch.h, and arch/*/src/*_rtc.h: Removed all of the old, malformed RTC interface definitions from include/nuttx/rtc.h. The necessary prototypes have been removed, renamed, scattered to the wind, hidden under rocks, -- whatever it takes to make it clear that there is no RTC interface callable from application code (2015-02-13). * include/nuttx/rtc.h and fs/ioctl.h: Begin the definition of a proper, driver based RTC interfaces that is better suited to the architectural goals of nuttx (2015-02-13). * drivers/timers/timer.c and watchdog.c: Move timer-related drivers from drivers/ to drivers/timers (2015-02-13). * drivers/timers/rtc.c: Add an RTC upper half driver. This is the driver that is documented in include/nutt/rtc.h (2015-02-13). * arch/arm/src/stm32/stm32_rtcc.c and stm32_rtc.h: Break out a new internal interface, stm32_rtc_setdatetime(). This eliminates some un-necessary time conversions. From Freddie Chopin (2015-02-13). * arch/arm/src/stm32/stm32_rtc_lowerhalf.c, Make.defs, and stm32_rtc.h: Add a skeleton implementation of the RTC lower half interface at arch/arm/src/stm32/stm32_rtc_lowerhalf.c. This is just the framework for the RTC lower half. None of the interface methods have yet been implemented (2015-02-13). * net/icmpv6/icmpv6_advertise.c and icmpv6_solicit.c: Add inclusion of nuttx/net.h to two files. Without these there can be compilation errors in certain configurations. From Max Neklyudov (2015-02-13). * net/net_initialize.c, sched/init/os_start.c, and a few other files: Divide net_intiialize() into net_setup() and net_initialize() to solve a chicken-and-egg problem. net_setup() must be called before up_initialize() is called so that networking data structures are ready to register new network devices. net_initialize() now does only timer related operations and is called AFTER up_initialize() where the timers are configured. Problem note by Max Neklyudov (2015-02-14). * include/time.h and sys/time.h: Move struct timeval from include/time.h to include/sys/time.h where it belongs (2015-02-15). * arch/arm/src/stm32/stm32_rtcc.c, stm32_rtc.h, and Kconfig: Extend the RTC interface to support reading subseconds. From Jussi Kivilinna (2015-02-16). * arch/arm/src/efm32/efm32_usbdev.c: EFM32 USB Device is now basically functional with this change. From Pierre-noel Bouteville (2015-02-16). * include/nuttx/net/ip.h: Move macros and common logic for IPv4-mapped IPv6 addresses from files in net/ to include/nuttx/ip.h. These are currently only used for UDP, but will need to be be used in many places in the future (2015-02-17). * includes/nuttx/compiler.h: Add support for the restrict keyword (2015-02-17). * include/netdb.h: Add a mostly-commented-out version of the standard netdb.h header file (2015-02-17). * arch/arm/src/tiva/: Updated files to allow for ADC triggering by the timer. I’ve cleaned up some parts of the ADC code, too, and fleshed out the PWM triggering ioctl. From Calvin Maguranis (2015-02-17). * configs/tm4c123g-launchpad: Add ADC support. From Calvin Maguranis (2015-02-17). * fs/fat/fs_mkfatfs.c: Use DMA memory for mkfatfs when needed. This makes mkfatfs use fat_dma_alloc() when CONFIG_FAT_DMAMEMORY is set. This is needed to ensure mkfatfs operates with boards that use DMA for microSD. From Andrew Tridgell via the PX4/NuttX repository (2015-02-17). * include/nuttx/rtc.h, fs/fs.h, drivers/ramdisk.c, pipes/, and timers/rtc.c: The inode unlink method should not be support if operations on the root pseudo-filesystem are disabled (2015-02-18). * include/nuttx/sched timing functions: Fix some nanosecond comparisons. Comparisons should be greate than OR EQUAL TO 1000000000 for maximum value of nanoseconds in struct tm. From Juha Niskanen (2015-02-20). * tm4c123g-launchpad: Add board button interrupt logic. From Calvin Maguranis (2015-02-20). * "Tiva: Move GPIO prototypes out of arch/arm/include/tiva/irq.h to arch/arm/tiva/tiva_gpio.h where they belong (2015-02-20). * arch/arm/src/tiva: Tiva GPIO clean-up by Calvin Maguranis (2015-02-20). * arch/arm/src/stm32/stm32_pwr.c, stm32_pwr.h, and stm32_rtcc.c: Changes to support fully write protecting the backup domain. N.B. stm32_pwr_enablebkp did not account for the delay from enable to the domain being writable. The KISS solution is a up_udelay. A more complex solution would be a negated write test with restore. From David Sidrane (2015-02-21). * arch/arm/src/stm32/stm32_bbsram.c, stm32_bbsram.h, Kconfig, and Make.defs: Adds the ability to use the STM32F2 and STM32F4 Battery Backedup SRAM in the file system. With an option to Save Panic context to one of the files. From David Sidrane (2015-02-21). * configs/pic32mx-starterkit: Rename from pic32-starterkit to make room on the namespace for a pic3mz-starterkit. Update src/ directory file naming to match current standard. Refresh configurations. Move linker scripts to a new scripts/directory. Make sure that it builds using the Pinquino toolchain (2015-02-21). * arch/mips/src/mips32/Toolchain.mk: Current Pinguino toolchain uses the prefix p32- instead of mips- (2015-02-21). * configs/pic32mz-starterkit: Add basic board support for the PIC32MZ (can't build yet of course because there is not yet any PIC32MZ support) (2015-02-22). * arch/mips/src/pic32mz and include/pic32mz: Add some PIC32MZ header file definitions and just enough logic in the source directory so that we can run 'make menuconfig'. Still a very long way from being complete (2015-02-22). * libc/time/lib/lib_sfrtime.c: Missing implementation of %C in sfrtime() C (was being treated as %y). From Freddie Chopin (2015-02-23). * drivers/can.c: In the can_open function: this line 'dev->cd_ocount = tmp;' needs to be moved a few lines down otherwise the open count will only be incremented from 0 to 1. This causes problems when trying to open the can bus from two different tasks. SourceForge Patch #46 from Anonymous (2015-02-23). * Tiva TM4c1294: Updates from Frank Sautter (2015-02-24). * fs/aio: correct some backward tests in aio_read() and aio_write(): Socket descriptors have higher numbers than file descriptors. In aio_contain(), Copy u.ptr (void *) when initializing aioc and not the case specific u.aioc_filep. From Michal Ulianko (2015-02-24). * include/pthread.h: Fix PTHREAD_COND_INITIALIZER (2015-02-24). * sched/clock/clock_systimespec.c: When an RTC is used clock_systimespec() must subtract the basetime from the returned time. It needs to return the time since power up, no the current time. Issue noted by Max Neklyudov (2015-02-25). * fs/vfs/fs_select.c and sched/semaphore/sem_timedwait.c: Fix places where the errno value was being overwritten by subsequent actions so that the returned errno value was incorrect. From Max Neklyudov (2015-02-25). * include/sys/select.h: Extend the fd_set type definition so that it can handle more than 32 descriptors (if so configured). From Max Neklyudov (2015-02-25). * net/netdev/netdev_unregister.c: Fix a list handling error in netdev_unregister(). From Max Neklyudov (2015-02-27). * net/netdev/netdev_register.c: Improve the network device registration logic. When multiple link types are used, modify how each interface number is assigned to the device name by incrementing the device number individually for each interface link type. From Max Neklyudov (2015-02-27). * include/nuttx/board.h: Remove common board function prototypes from other files and consolidate them in this new header file (2015-02-27). * arch/mips/src/pic32mz/: Implement support IO port interrupts (2015-03-01). * configs/pic32mz-starterkit/src: Add support for on-board buttons (2015-03-01). * include/nuttx/spi/spi.h: Add an SPIDEV_USER so that there can be board-specific definitions of SPI devices (2015-03-01). * arch/arm/src/stm32 and arch/arm/src/stm32: Adds architecture support for the STM32F372 and F373 (no board support yet). Only tested on STM32F373CC, but should work on the rest. Contributed by Marten Svanfeldt (2015-03-01). * arch/mips/src/pic32mz/pic32mz-spi.c and chip/pic32mz-spi.h: Add support for a basic SPI driver for the PIC32MZ (2015-03-03). * include/nuttx/i2c.h: Add a user provided void * argument to the I2C callback method for the I2C slave interface. Suggested by Nate Weibley (2015-03-03). * crypto/, include/nuttx/crypto, and arm/src/common/up_initialize.c: Fix issues when AES support was added for the STM32L1. From Juha Niskanen (2015-03-04). * arch/arm/src/stm32/stm32_spi.c and .h: Add missing SPI callback functions to the STM32 SPI driver. From Freddie Chopin (2015-03-04). * arch/*/src/*/*_assert.c, configs/Kconfig, and include/nuttx/board.h: Add support for dumping board-specific information on assertion. From David Sidrane (2015-03-04). * drivers/spi/Kconfig: Add missing CONFIG_SPI_CALLBACK selection. Noted by Freddie Chopin (2015-03-04). * arch/arm/src/samv7 and include/samv7: Add basic build directories and configuration logic for the Atmel SAMV7 family (2015-03-05). * arch/arm/src/Makefile, armv7-m/Toolchain.defs: Make ARM build system Cortex-M7 ready (2015-03-05). * arch/arm/src/sam34/sam_start.c: Leverage start-up logic from STM32 to (1) Enable the FPU and (2) perform IDLE stack coloration (2015-03-05). * arch/arm/src/armv7-m/up_lazyexception.S, Kconfig and severl other files: Add support for lazy FPU state saving. Not yet verified. (2015-03-06). * arch/arm/Kconfig, Make.defs, sam_start.c, configs/Kconfig, samv71-xult: Add a bare bones framework that will do nothing more than support configuration for the Atmel SAMV71 Xplained Ultra board. Very much a work in progress (2015-03-06). * sched/mqueue/mq_timedsend.c: Should not check for valid time if there is space in the message queue. Noted by Freddie Chopin (2015-03-10). * arch/arm/src/tiva/tiva_timerlib.c: Fix a typo in peripheral wait logic: gptm, not gpio. From Bradley Noyes (2015-03-10). * drivers/net/tun.c, Make.defs, include/nuttx/net/net.h, tun.h, and net/Kconfig: Add TUN device. From Max Neklyudov (2015-03-11). * fs/fat/fs_fat32.c: fat_unbind() was accessing 'fs->fs_sem' after freeing the 'fs' struct. From Juha Niskanen (2015-03-11). * fs/procfs/fs_procfsproc.c: fs_procfsproc: Fix potential NULL pointer dereference of 'node'. From Juha Niskanen (2015-03-12). * sched/sched/sched_waitpid.c: Do not use uninitialized boolean in waitpid(). From Juha Niskanen (2015-03-12). * libc/stdio/lib_ungetc.c:Fix NULL pointer dereference in ungetc(). If 'stream' was NULL, 'stream->fs_oflags' was evaluated. From Juha Niskanen (2015-03-12). * arch/arm/src/stm32/stm32_i2c.c: Add missing NULL check. From Juha Niskanen (2015-03-12). * drivers/usbdev/usbmsc_scsi.c: Add NULL pointer check. From Juha Niskanen (2015-03-12). * drivers/bch/bchdev_driver.c: Avoid NULL pointer dereference when bch->refs == 255. From Juha Niskanen (2015-03-12). * arch/arm/src/armv7-m/mpu.h: Bad syntax in ARMv7-M MPU logic would cause failure to write the correct value to the MPU_RASR register. From Juha Niskanen (2015-03-12). * net/socket/net_dupsd.c: Do not call sockfd_socket() twice. From Juha Niskanen (2015-03-12). * arch/arm/src/stm32/stm32_usbdev.c: Fix stale initialization invalidating later NULL check. From Juha Niskanen (2015-03-12). * arch/arm/src/stm32/stm32_serial.c and chip/stm32f10xxx_dma.h: Fix RX DMA setup for UART5. From Jussi Kivilinna (2015-03-13). * arch/arm/src/stm32/stm32_serial.c: Make input hardware flow-control work with RX DMA. From Jussi Kivilinna (2015-03-13). * drivers/pipes/pipe_common.c: Fix zero-lenth writes to pipes/FIFOs. From Jussi Kivilinna (2015-03-13). * drivers/serial/serial.c: Report correct number of bytes free in serial buffer with FIONWRITE. From Sami Pelkonen via Jussi Kivilinna (2015-03-13). * drivers/mmcsd/mmcsd_spi.c: Debugging and manuals (this one https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf and this one https://www.sdcard.org/downloads/pls/simplified_specs/part1_410.pdf) shows that ACMD23 must be preceded with CMD55 command as any other ACMD commands. Also, after the block reading wait loop must be inserted before writing the next block of data to the sd card. From Dmitry Nikolaev via Jussi Kivilinna (2015-03-13). * arch/arm/src/efm32/efm32_i2c.c: Add I2C driver. From Pierre-noel Bouteville (2015-03-14). * fs/mount/, include.sys/mount, syscall/: Add umount2(). umount() is now a macro that just calls umount2() with flags = 0 (2015-03-14). * fs/mount/fs_umount2.c, all file systems, include/nuttx/fs/fs.h: Pass the umount2() flags to every unbind() implementation. That is where the decision to umount or not will be made (2015-03-14). * fs/fat/fs_fat32.c: Fix a bug in the FAT unbind() logic. There were problems with the way certain internal list handling was implemented. The end result is that newly opened or cloned file structures were never being added to the list of open files. So when the unmount() happens, it always looked like there were not open files and a crash could ensue (2015-03-14). * fs/fat/fs_fat32.c and fs_fat32.h: Add support for umount2(target, MNT_FORCE) in the FAT file system (2015-03-15). * drivers/mmcsd/mmcsd_sdio.c: Fix some bad logic when file system debug is turned on: Arguments to syslog were missing so that garbage was being printed (2015-03-15). * arch/arm/src/sama5/sam_hsmci.c: Fix a bug in SAMA5 HSMCI. The bitfield mask and shift values were reversed resulting in a trashed value for the number of blocks in the BLOCKR register. This was sufficient to prevent DMA writes from working (2015-03-15). * drivers/mtd/at24xx.c, Kconfig, and include/nuttx/fs/ioctl.h: Add support for (1) the byte-oriented read() method, (2) devices that have extended memory regions, and (3) devices that use 8-bit addressing (2015-03-17). * arch/mips/src/mips32/Kconfig, Toolchain.defs, and configs/pic32mz-starterkit/nsh/Make.defs: Changes that will permit building of the PIC32MZ Start Kit configuration using MPLAB and the XC32 toolchain. From David Sidrane (2015-03-17). * arch/arm/src/stm32/stm32_rtc_lowerhalf.c: Fix some errors in the STM32 RTC lower-half driver that cause compilation failures. From shilo.xyz (2015-03-19). * arch/arm/src/sama5/chip/sam_tc.h: Fix typos in timer/counter header file. From Bob Doiron (2015-03-20). * configs/olimexino-stm32: Board support for the Olimexino STM32 board from David Sidrane (2015-03-20). * PIC32MZ: Incorporated a set of patches that makes the basic NSH configuration on the PIC32MZ Starter Kit. From Kristopher Tate (2015-03-22). * arch/arm/src/tiva: (1) ADC driver has been re-organized; configuration is now handled in code instead of Kconfig to help reduce bloat and confusion. (2) Timer changed to remove ADC coupling in Kconfig to code and moved configuration up from arch/arm/src/tiva to configs/tm4c123g-launchpad/src. (3) GPIO driver needed small fixes in the configuration routines and discovered false-positive bugs in interrupt testing: interrupts are now verified to actually be working reliably. (4) Attempt to apply some consistency in the tiva arch/ level's interface to the config/board/ level driver configuration. From Calvin Maguranis (2015-03-23). * arch/mips/src/pic32mz: Various fixes for Ethernet support. Still not fully functional. From Kristopher Tate (2015-030-29). * arch/arm/src/armv7-m: Add configuration option and logic to support the D-Cache in write-through mode (2015-03-29). * arch/arm/src/stm32/Kconfig, stm32_lse.c, stm32_lsi.c, stm32_rtc.c/.h, stm32_rtcc.c, stm32_rtcounter.c, and stm32f*_rcc.c: The STM32F4Discovery board doesn't come with a Low speed external oscillator so the default LSE source for the RTC doesn't work. In stm32_rtcc.c the up_rtc_initialize() logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call that rightfully enables the lsi clock; but the next times, when the rtc is already setup, the rtc_resume() call does NOT start the lsi clock! The right place to put LSE/LSI initialisation is inside stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked the possible uses of the LSI and the LSE sources: the LSI can be used for RTC and/or the IWDG, while the LSE only for the RTC (and to output the MCO1 pin). This change is not verifed for any other platforms. From Leo Aloe3132 * Rename arch_nshinitialize() to board_app_initialize() (2015-03-30). * ./*.mk, configs/.gitignore, Makefile, boardctl.c, include/nuttx/fs/ioctl, include/sys/boardctl.h, syscall.h, and syscall/: Add a new non- standard OS interface called boardctl(). This is similar to a driver IOCTL call. But this is an IOCTL call directly on the board logic. This function will eventually replace all of the ad hoc OS interfaces that are current used to perform application specific initialization and application driver test configuration. It essentially formalizes and institutionalizes these rogue interface in to at least a single crazy call (2015-03-31). * configs/: Modify all configurations: Make sure that CONFIG_LIB_BOARDCTL=y appears wherever CONFIG_NSH_ARCHINIT=y appears. Remove support for CONFIG_NSH_ARCHMAC. It is not used and there are better ways to do that operation (2015-03-31). * configs/Kconfig, boardctl.c, all touchscreen driver setup functions, include/board.h, include/sys/boardctl.h, and include/nuttx/input/touchscreen.h: arch_tcinitialize() and arch_tcunitinitialize() renamed to board_tsc_setup() and board_tsc_teardown(). These are not long called directly by applications but only indirectly throught the crappy boardctl() OS interface (2015-03-31). * configs/Kconfig, boardctl.c, include/nuttx/board.h, include/sys/boardctl.h, and several ADC files in configs//src/: Rename adc_devinit() to board_adc_setup(). Add support to the boardctl() interface so that it can call board_adc_setup() on behalf of an application. Make sure that the proper features are enabled in the defconfig files that have CONFIG_EXAMPLES_ADC=y (2015-03-31). * configs/*/defconfig: Make sure that all defconfig files that require external graphics intiialization also enable the correct boarctl() settings (2015-03-31). * include/nuttx/board.h, include/sys/boardctl.h, nuttx/configs/Kconfig and boardctl.c, and board configurations and PWM implementations: Rename pwm_devinit() to board_pwm_setup(). Add CONFIG_BOARDCTL_PWMTEST that will enable calling board_pwm_setup() from boardctl(). In all configurations that enable the apps/examples/pwm test, make sure that boardctl() support is properly enabled (2015-03-31). * Move include/nuttx/timer.h, rtc.h and watchdog.h to include/nuttx/timers/. (2015-04-01). * drivers/timer/cs2100-cp.c and include/nuttx/timers/cs2100-cp.h: Add a very basic driver for the CS2100-CP Fractional-N Multipler chip (2015-04-02). * configs/, graphics/, include/nuttx: More renaming: up_lcdinitialize->board_lcd_initialize, up_lcdgetdev->board_lcd_getdev, up_lcduninitialize->board_lcd_uninitialize (2015-04-04). * include/nuttx/nx, libnx/nx, libnx/nxtk: Add a new 'capped' parameter to nx_drawline(), nxtk_drawlinetoolbar(), and nxtk_drawlinewindow() (2015-04-05). * libnx/nx/nx_drawline.c, libnx/nxtk/nxtk_drawlinetoolbar.c and nxtk_drawlinewindow.c: Implement line caps by drawing a file circle at the each endpoint of a line with a radius equal to half of the width of the line (2015-04-05). * include/time.h, nuttx/time.h, libc/time/lib_dayofweek.c and lib_gmtimer.c: Implements CONFIG_TIME_EXTENDED as we discussed relative to providing the last 3 members of the tm struct and support for filling them in and even using the wday in the STM32 RTC. From David Sidrane. * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: A side-effect of changing serial settings via TERMIOS (such as tcsetattr) is that serial interrupts were being left disabled. This is not a problem if the serial configuration is changed when there are no open references to the serial device. In that case, serial interrupts are disabled and will not be enabled enabled until the serial device is first opened. But it is fatal if the serial device is already opened and if there is a task waiting to receive data. In that case, the side-effect of disabling interrupts is fatal: That task is then left hanging with interrupts disabled (2015-04-08) * arch/arm/src/sama5/sam_serial.c: Backport support for flowcontrol and termios from SAM3/4 -- UNVERIFIED. (2015-04-08). * arch/arm/src/sam34/sam_serial.c and samv7/sam_serial.c: The IMR register is read-only. This means that sam_restoreints() did not actually re-enable UART interrupts (2015-04-08). * sigaddset() and sigdelset(): Need to set errno if a bad signal number is received (2015-04-09). * sighold(), sigrelse(), sigignore(), sigset() and sigpause(): New signal handling functions (2015-04-09). * Fixes to asinh(), atanh(), and sinh(): The 'basic' expansions all exhibited bad cancellation errors near zero (<= 1E-10). This can be easily seen e.g. with x = 1E-30, the results are all zero though they should be extremely close to x. The cutoff values (1E-5, 1E-9) are chosen so that the next term in the Taylor series is negligible (for double). Functions could maybe be optimized to use only first term (x) and a smaller cutoff, just bigger than where the cancellation occurs (2015-04-09). * syscall/syscall.csv: Last changes to message queue prototypes did not make it into call gate logic (2015-04-09). * syscall/syscall_stublookup.c: Fix some errors that crept in recently (2015-04-09). * libc/time/lib_localtime.c: Inconsistent configuration name: CONFIG_LIBC_TZDIR vs CONFIG_LIBC_TZ_TZDIR. Former wins (2015-04-11). * libc/time/lib_calendar2utc.c and lib_mktime.c: Fix an error in time initialization when there is not RTC and the time is initialized from a fixed configured value. The call to clock_calendar2utc() was returning the time in units of seconds. The initialization logic, however, was expecting to get time in units of days. This problem has been there forever but obviously has not significant impact to behavior in systems where time is not visible (2015-04-12). * fs/fat/fs_fat32utils.c: Fix misthink when CONFIG_ENDIAN_BIG=y. From Lwazi Dube (2015-04-12). * include/nuttx/net/netdev.h, net/devif/ipv6_input.c, icmpv6/icmpv6_rsolicit.c and net/icmpv6/icmpv6_solicit.c: Use common macro(s) for calculating link layer header length. From Brennan Ashton (2015-04-13). * apps/netutils/pppd/Kconfig, pppd.c, and ntpv3.h (removed): Remove ntpclient header file in and NTP client references from the pppd dir. From Brennan Ashton (2015-04-13). * configs/galileo: Remove all references to the Galileo board. That port is not going to happen (I don't even have the hardware anymore) (2015-04-13). * drivers/input/max11802.c: Fix possible unmatched IRQ restore. Noted by Juha Niskanen (2015-04-14). * atexit(): Fix reference to undefined variable in certain configurations. From Juha Niskanen (2015-04-14). 7.10 2015-06-09 Gregory Nutt * configs/sim/src/sim.h, sim_zoneinfo.c, Makefile, and sim_boot.c: Add logic to test localtime and TZ database. See apps/system/README.txt for info (2015-04-15). * libc/Kconfig: Fix defaults for timezone limits. They need to be much larger (2015-04-15). * Watchdog files: Fix repeated typo wachog.h in several watchdog drivers (2015-04-15). * configs/boardctl.c and Kconfig: Add missing causing that caused failures of PWM test (2015-04-15). * arch/arm/src/stm32: Defines a second interface for the dma2d controller. Controlling both LTDC and DMA2D was unpractical from the programmers view because both controllers are to different. LTDC only controls the display visibility but the DMA2D controller changes the content of the frame buffer (buffer of the layer). The main features are: 1. DMA2D interface Supports the nuttx pixel formats: - FB_FMT_RGB8 - FB_FMT_RGB24 - FB_FMT_RGB16_565 Dynamic layer allocation during runtime for the supported formats - The number of allocatable layer can be configured. Supported dma2d operation: - blit (Copy content from source to destination layer) also works with selectable area. - blend (Blend two layer and copy the result to a destination layer which canbe a third layer or one of the source layer) also works awith selectablerea. - fillarea (Fill a defined area of the whole layer with a specific color) As a result of that the dma2d controller can't transfer data from the core coupled memory, CCM is disabled but usable by the ccm allocator. Currently the ccm allocator is used for allocating the layer structure only. For the dma memory (layers frame buffer) memory is allocated from heap 2 and 3. 2. LTDC interface I have changed the api for the currently non implemented operations: - blit (Copy content from a dma2d layer to an ltdc layer) also works with selectable area. - blend (Blend two dma2d layer and copy the result to a destination ltdc layer) also works with selectable area. Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer is a layer referenced by the dma2d interface. One of the most important questions for me was, How can i flexible use an ltdc layer with the dma2d interface, e.g. as source layer for dma2d operations? Get the layer id of the related dma2d layer by a special flag when using getlid() function of the ltdc interface and use the layer id to reference the specific dma2d layer by the dma2d interface. The ltdc coupled dma2d layers are predefined and can't be dynamically allocated of freed. They use the same frame buffer memory and the same color lookup table. Changes: - layer internal format of the clut table - interrupt handling for register reload (vertical vblank) instead using waiting loop - small fixes and refactoring From Marco Krahl (2015-04-16). * Add support for the new DMA2D features to the STM32F429i-Disco LTDC configuration. From Marco Krahl (2015-04-16). * stdlib.h: MAX_RAND should be RAND_MAX (2015-04-16). * STM32F429i Disco: (1) Fix a bad return value if the LCD driver is already initialized. (2) The LCD driver initialization is now performed during the early boot sequence. (3) Increased the size of the message queue from 32 to 64 in the lcd configuration. From Marco, ocram.lhark@yahoo.com (2015-04-17). * STM23 RTC: Fix an error introduced into stm32_pwr_enablebkp(). That function must preserve the previous state of backup domain access on return (2015-04-19). * include/nuttx/usb/hub.h: Add USB hub header file from Kaushal Parikh (2015-04-18). * drivers/usbhost/usbhost_hub.c: Bring in USB hub-related files from https://github.com/kaushalparikh/nuttx. This is the work of Kaushal Parikh. This initial commit is incomplete. This is quite a bit more hub logic that needs to come in before the port is complete (2015-04-18). * arch/arm/src/stm32/stm32_rtcounter.c: Now need to enable backup domain write access when setting the time. From Darcy Gong (2015-04-19). * include/nuttx/usb/usbhost.h: Bring in more logic from https://github.com/kaushalparikh/nuttx (2015-04-19). * drivers/usbhost/usbhost_enumerate.c: Last of USB hub logic from https://github.com/kaushalparikh/nuttx (2015-04-19). * include/time.h: Add prototypes for localtime() and localtimer_r() (2015-04-21). * include/assert.h: Wrap definitions of assertion macros in do while. Suggested by orbitalfox (2015-04-22). * sched/semaphore/sem_wait.c: Missing comma on debug statement caused compile error with DEBUG on. Why hasn't that been noted before? (2015-04-23). * drivers/lcd and include/nuttx/drivers: RA8875 LCD driver contributed by Marten Svanfeldt (2015-04-24). * arch/arm/src/stm32/chip/stm32_pwr.c and .h: Adds support for STM32's Programmable Voltage Detector (PVD) feature. Register access is behind CONFIG_STM32_ENERGYLITE as the feature has not been verified for F1/F2/F4 etc. manuals. Tested on STM32L1. PVD interrupt looks generic, at least #defines it needs are in headers for every chip variant. By Dmitry Nikolaev, submitted by Juha Niskanen (2015-04-28). * arch/arm/src/stm32/chip/stm32_exti.h, stm32f30xxx_memorymap.h, and stm32f37xxx_memorymap.h: Added missing EXTI definitions for the STM32 F3; Correct an error the port D base address in the STM32 F30x and F37x memory maps. From Greg Meiste (2015-05-01). * arch/arm/src/lpc17xx/lpc176x_gpio.c: Reorder steps when an output GPIO is configured in order to avoid transient bad values from being output. From Hal Glenn (2015-05-02). * arch/arm/src/stm32/stm32_otgfsdev.c and stm32_otghsdev.c: Add protection in the event that out-of-bound endpoint numbers are received. From David Sidrane (2015-05-02). * USB host: Merged in the USB hub support that has been happening on a separate branch up until this point. The interfaces are complete and most platforms have been verified (still a little to be done however). (2015-05-02) * arch/arm/src/lpc31xx/lpc31_ehci.c, chip.h, sama5/sam_ehci.c, and chip.h: Fix cache related problem in LPC31 and SAMA5Dx EHCI drivers. All buffers are now aligned with the cache line size in both starting address and in length. This cause major problems in unlucky builds where the USB host buffers where unaligned and abutting other data. The cache flush and invalidate operations could be subverted by accesses to adjacent data or could have unexpected side effects. This bug has been in the ECHI drivers forever, but was only revealed due to unlucky memory allocations during the integration of the hub feature (2015-05-03). * arch/arm/src/lpc17xx/lpc17_usbhost.c: Correct some initialization of data structures. When hub support is enabled, it would overwrite the end of an array and clobber some OS data structures (2015-05-03). * configs/olimex-lpc1766stk: Make stacks usage configurable for USB host waiter. It needs to be a lot deeper when hub support is enabled (2015-05-03). * fs/vfs/fs_poll.c: Fix resource leak and memory corruption on poll failure. From Jussi Kivilinna (2015-05-04). * All USB host drivers in arch/ and all USB class drivers in drivers/usbhost: Modify the transfer() and asynch() methods so that the actual size of the transfer is returned. Unverified on initial commit (2015-05-05). * drivers/usbhost/usbhost_cdcacm.c: Add initial implementation of a host- side CDC/ACM driver. Completely untested on initial commit (2015-05-06). * configs/, drivers/usbhost/usbhost_storage.c, and included/nuttx/usb/usbhost.h: Rename usbhost_storageinit() to usbhost_msc_initialize(). Add calls to usbhost_cdcacm_initialize() if CONFIG_USBHOST_CDCACM is selected (2015-05-06). * arch/arm/include/kl and src/kl: Add support for the KL25Z64. The KL25Z64 is a lower memory variant of the KL25Z128 and is used on the Teensy LC. From Michael as SourceForge patch 50 (2015-05-07) * configs/teensy-lc and related board support files: Add board support for the Teensy LC board. Support is based off the Freedom KL25Z board. LED, PWM, and UART0 have been tested. The SPI pins are mapped correctly but have not yet been tested. From Michael Hope as SourceForge patch 51 (2015-05-07). * arch/arm/src/kl/kl_pwm.c: Fix PWM debugging. TPM1 and TPM2 have two channels instead of six and will hard fault if you try to read the missing channels. From Michael Hope (2015-05-07). * arch/arm/src/kl/kl_lowputc.c: enable the clocks to UART1 and UART2. The previous version would cause a hard fault on startup due to the modules not being clocked. Also drop the GPIO configuration as it's done during kl_start(). From Michael Hope (2015-05-07). * teensy-lc: remap UART0 to the standard pins. From Michael Hope (2015-05-07). * arch/arm/src/stm32 and include/stm32: Added support for STM32F302K8 and STM32F302K6. From Ben Dyer via PX4/David Sidrane (2015-05-08). * configs/compal_e86: Calypso Compal-E86: Updates for execution out of FLASH on the C139 phone. From Craig Comstock (2015-05-08). * STM32 F3: Add DBGMCU register definitions for the F3 family. From Greg Meiste (2015-05-09). * arch/arm/src/stm32/chip/stm32_exti.h: Add EXTI line definitions for the STM32L family (2015-05-09). * net/tcp/tcp.h: Correct failures in long Telnet sessions by increasing the size of the number of bytes sent from uint16_t to uint32_t. This avoids an integer overflow that causes a Telnet sessions to be closed unexpectedly. From Rony XLN (2015-05-12). * include/stdio.h, sys/statfs.h, cxx/cstdio, and syscall/syscall.csv: Remove duplicate prototype of statfs from stdio.h. Belongs in sys/statfs.h only. Note by Michael Hope (2015-05-12). * arch/arm/include/kl/chip.h: Fix typo in header file. From Michael Hope (2015-05-12). * arch/arm/src/kl/chip/kl_tpm.h: Fix offset to the TPM status register. From Michael Hope (2015-05-12). * net/local/local_connect.c: Correct some network lock logic: Two error conditions where the network was not being unlocked and one where it was getting unlocked twice. From Jussi Kivilinna (2015-05-12). * net/local/, fs/vfs/fs_poll.c, drivers/pipes/pipe_common.c/.h, include/nuttx/fs/fs.h: Add poll support for Unix stream sockets. From Jussi Kivilinna (2015-05-12). * net/local/: Local stream sockets had problem of double releasing pipes (both server and client attempt release), which causes wrong pipe pair being closed in multi-client case. Solve by adding per connection instance ID to pipe names. From Jussi Kivilinna (2015-05-12). * drivers/usbdev/ all class drivers: There needs to be a check to make sure that the size of a returned string does not exceed the size of the allocated request buffer. Strings such as vendor names or product names will be truncated to fit in the request buffer (2015-05-12). * arch/arm/src/samv7/sam_twihs.c: Fix SAMV TWIHS logic that performs multi-message transfers with and without repeated starts (2015-05-12). * maXTouch Xplained Pro: The above TWIHS fix was the last barrier to getting the touchscreen working in the maXTouch Xplained Pro LCD (2015-05-12). * net/route/ and net/netdev/netdev_ioctl.c: Complete implementation of the IPv6 routing logic. From Max Neklyudov (2015-05-13). * net/udp/: Add inclusion of assert.h in networking files where needed to avoid compilation errors. From Max Neklyudov (2015-05-13). * /net/route/netdev_router.c: Fix bug in IPv6 router from Max Neklyudov (2015-05-13). * sched/pthread/pthread_kill.c: Re-implemented pthread_kill(). It was just a simple wrapper around kill() but since the correct dispatching of signals for multi-threaded task groups has been implemented, calling kill() does not do what pthread_kill() is supposed to do. The corrected implementation of pthread_kill() will direct the signal specifically to the specific pthread and no other (2015-05-13). * arch/arm/include/samdl, arch/arm/src/samdl, configs/samd20-xplained: Rename the samd/ directories and configuration varialbes to samdl to all the same directory structure to support the SAML21 (2015-05-14). * arch/arm/include/samdl and arch/arm/src/samdl: And chip definitions, configuration framework, and placeholder memory map and pin configuration files for SAML21 support. Still incomplete on initial commit (2015-05-14). * include/nuttx/wdog.h, sched/mqueue/mq_timed*.c, semaphore/sem_timed*.c, signal/sig_timed*.c, timer/timer_settime.c, and wdog/wd_start.c: Update the type passed to watchdog timer handlers. Using uint32_t is a problem for 64-bit machines (2015-05-18). * configs/saml21-xplained: Add a board build configuration for the SAML21 Xplained Pro. Initial commit is just the SAMD20 Xplained Pro board support with naming changed. Does not yet build (2015-05-18). * libc/net/lib_inetntoa.c: Correct errors in printing IP address when type char is signed. From Max Neklyudov (2015-05-19). * arch/arm/src/efm32/efm32_rtc_burtc.c: Updated EFM32 RTC driver from Pierre-noel Bouteville (2015-05-19). * arch/arm/src/tiva/chip/tm4c_memorymap.h, tm4c_pinmap.h, and vectors.h. configs/tm4c1294-launchpad/include/board.h and src/tm4c_autoleds.c: Fixes for Tiva TM4C1294NCPDT. From Frank Sautter. (2015-05-20). * configs/tm4c1294-launchpad/include/board.h: Added TM4C1294NCPDT EN0_LED2 (10/100-Base-Tx); removed all booster pack pin definitions. From Frank Sautter (2015-05-20). * nuttx/arch/arm/src/sam34/sam_serial.c: In NONBLOCKING mode serial does not receive bytes from UART. This happens because RX interrupt was disabled in the setup routine. To fix this I save interrupt configuration before UART shutdown and restore it after. From Max Neklyudov (2015-05-21). * arch/arm/include/lpc11xx and src/lpc11xx: Support for the LPC11xx family (the LPC1115 MCU in particular). Contributed by Alan Carvalho de Assis (2015-05-22). * configs/lpcxpresso-lpc1115: Support for the LPCXpression LPC1115 board. Contributed by Alan Carvalho de Assis (2015-05-22). * arch/arm/src/sam34/Kconfig, sam_serial.c, and chip/sam_uart.h: Add support for optical mode for the SAM4CM UART1. From Max Neklyudov (2015-05-23). * arch/arm/src/lpc11xx/: Add support for up_getc() which is needed for NSH if there is no file system. From Alan Carvalho de Assis (2015-05-23). * LPCXpresso-LPC1115: Add a minimal NSH configuration that has the file system disabled. Update README with OpenOCD instructions. From Alan Carvalho de Assis (2015-05-23). * Fix numerous typos in configuration variable names. Tracked down by Alan Carvalho de Assis (2015-05-23). * configs/teensy-2.0: Rename configs/teensy so that it is clearly distinguished from teensy-lc and teensy-3.1 (2015-05-15). * include/nuttx/mtd/mtd.h: Increase the size of the fields in the geometry structure (again) to support larger FLASH sizes. Needed by Sbastien Lorquet (2015-05-26). * SAM4CM and SAMA5D Free-running timer: Logic that samples the free running counter reads the pending interrupt status register and can cause interrupts to be lost. So, if when the status register is read, the logic must also handle the timer overflow event. Found and fixed by Max Neklyudov (2015-05-26). * arch/arm/include/kinetis and arch/arm/src/kinetis: Basic support for the Kinetis K20 architecture. Taken from PX4. This is the work of Jakob Odersky (2015-05-26). * net/: Move some ICMP event lists to the device structure. That allows for both device-specific event processing and also devices to generate events like network down. From Max Neklyudov (2015-05-27). * net/: Extend Macs logic to ARP and ICMPv6. Also found and fix several IPv6-related compilation errors that have crept in. IPv6 has been broken for awhile (2015-05-27). * net/tcp: Fix an important TCP networking bug: 16-bit flags was being converted to 8-bits in a few locations, causing loss of status indications (2015-05-27). * net/socket and net/tcp: net_startmonitor.c always returned OK. In the case where a socket has already been closed, it correctly handled the disconnection event but still returned OK. Returning OK caused the callers of net_startmonitor to assume that the connection was okay, undoing the good things that net_startmonitor did and causing the socket to be marked as connected. This behavior was noted by Pelle Windestam (2015-05-28). * include/nuttx/net, net/arp, net/devif, net/icmp, net/icmpv6, net/netdev, net/pkt, net/tcp, net/udp: Modify event list handling: Now there are two event lists each device structure: (1) One is for ARP and ICMP data related events, the other is for device related events. Callback allocation/free routines no accept a device parameter as well as a list: If the device parameter is added, then the callback goes into both the connection-related list AND the device event list. Thus each socket type can received both custom data-related events as well as common device related events (2015-05-28). * net/socket and net/utils: setsockopt() fails when setting timeouts to values less that an 100 msec. That is because the timeout is limited to stops of 1 decisecond and because the conversion of structure timeval was truncating the microsecond remainder. The utility net_timeval2dsec now accepts and option to determine how it handles the remainder: truncate, discarding the remainder, use the remainder to round to the closed decisecond value, or use any non-zero remainder to the next larger whole decisecond value. Bug discovered by Librae (2015-05-29). * configs/stm32f4discovery/src: Move up_cxxinitialize from nuttx/configs/stm32f4discovery/src to apps/platform/stm32f4discovery where it belongs (2015-05-29). * net/sockets, net/tcp, net/udp: UDP Networking: Add support for device event notification for UDP transfers (2015-05-29). * net/sockets and net/tcp: TCP Networking: Add support for device event notification for UDP transfers (2015-05-30). * libc/Kconfig and stdio/lib_libvsprintf.c: Add an option to disable support for long long formats in lib_vsprintf. From Alan Carvalho de Assis (2015-05-30). * net/net_initialize.c, net/detdev, and net/socket: The network device list was protected by a re-entrant semaphore. With the recent change to support network device callback, the network stack needs to access the network device list too. Some drivers, however, run the network stack from the interrupt level -- this is bad but a fact in the current state. Of course, those drivers are unable to take the semaphore and would assert. The solution here is to eliminate the device devices semaphore altogether. This eliminates netdev_semtake() and netdev_semgive() and replace them with net_lock() and net_unlock() which have the larger scope that is needed and will integrate properly with the dinosaur interrupt driven stack (2015-05-31). * net/socket/connect.c: In the TCP connection operation, it was trying to setup the network monitor BEFORE the socket was successfully connected. This, of course, has ALWAYS failed because the socket is not yet connected and the TCP state is not yet correct for a connected socket. However, because of other changes net_startmonitor() now returns a failure condition that causes worse problems when trying to connect. The fix is to move the logic that starts the network monitor to AFTER the socket has been successfully connected (2015-05-31). * tools/configure.c: Fix test for the existence of the apps/ directory. Fix backward interpretation of options, -l was selecting Windows and -w was selecting Linux. This was SourceForege Ticket #39 (2015-05-31). * arch/include/stm32/chip.h and arch/src/stm32/Kconfig: Add basic support for the STM32F205RG. From SourceForge Ticket 40 (anonymous, 2015-05-31). * arch/arm/src/lpc17xx: Review, update, and modify the Ethernet driver so that it works better with CONFIG_NET_NOINTS=y (2015-06-01). * configs/: Update all LPC17xx networking configurations so that they have CONFIG_NET_NOTINTS=y selected (2015-06-01). * /arch/arm/src/armv7-m, binfmt/libelf, configs/stm32f4discovery/scripts, /include/nuttx/binfmt, and libxx: Add support uClibc++ exceptions. This involves additional handling for relative relation types, additional support for unwinding, as well as additional changes. The culmination of a big effort from Leo Aloe3132 (2015-06-01). * configs/olimex-lpc1766stk: Rename the thttpd configuration to thttpd-nxflat. Add a new configuration, thttpd-binfs, that provides an example of how to build apps/netutils/thttpd using binfs instead NXFLAT+ROMFS (2015-06-02). * tools/cfgdefine.c: Extend the mkconfig tool so that it can dequote a quoted list of quoted strings. THTTPD uses such a configuration setting to provide the list of index files (2015-06-02). * mq_timedreceive(): move the location where the errno value is set; the ETIMEDOUT errno setting was being overwritten by subsequent actions before returning. Noted by Freddie Chopin (2015-06-03). * Networking: Modify how callback structures are stored to avoid another potential use of a stale pointer (2015-06-03). * POSIX message queues: Move mq_setattr() and mq_getattr() from nuttx/libc/mqueue to nuttx/sched/mqueue. Also add syscall support for mq_setattr() and mq_getattr(). This is necessary in protected and kernel builds because in those cases the message queue structure is protected and cannot be accessed directly from user mode code (2015-06-03). * drivers/net/tun.c: TUN driver bug fix. From Max Neklyudov (2015-06-03. * drivers/net/Kconfig, include/nuttx/net/mii.h, and arch/arm/src/lpc17xx/lpc17_ethernet.c: Add support for the Micrel KSZ8041 PHY to the LPC17xx Ethernet driver (2015-06-03). * configs/lincoln60/netnsh: Add a network enabled configuration for the Lincoln60 board (2015-06-03). * drivers/net/tun.c: Misc. improvements to the TUN driver, mostly related to poll(). From Max Neklyudov (2015-06-04). * fs/, fs/unionfs, include/nuttx, include/sys, Documentation: Add support for a union file system that can be used to overlay and merge the content of two mounted file systems (2015-06-05). * arch/arm/src/efm32/efm32_spi.c: Add SPI GPIO pin initialization. From Pierre-noel Bouteville (2015-06-05). * configs/sim/unionfs: Add a configuration for testing the Union File System (2015-06-05). * configs/lincoln60/thttpd-binfs: Add a thttpd-binfs configuration for the Lincoln60. That configuration still does not work on initial commit (2015-06-06). * arch/arm/src/sama5/sam_can.c: Fix SAMA5 CAN frame construction. From Max Holtzberg (2015-06-07). 7.11 2015-08-13 Gregory Nutt * arch/arm/src/efm32/efm32_spi.c: Correct write to incorrect register in EFM32 SPI driver. From Pierre-noel Bouteville (2015-06-09). * configs/teensy-3.x: Add board support for the PJRC Teensy-3.1 board (2015-06-09). * arch/arm/src/samdl, configs/samd20-xplained, and configs/saml21-xplained: In the SAML21, SERCOM5 uses a different SLOW clock channel (and, hence, also a different SLOW GCLK generator). This means that the channel selection cannot be a global definition but must be a per SERCOM configuration setting (2015-06-10). * arch/arm/src/kinetis and include/kinetis: Add support for MK20DN--VLH5 and MK20DX---VLH5. Needed for backward compatible support for Teensy-3.0 (2015-06-10). * configs/Kconfig and configs/teensy-3.x: Add support for Teensy-3.0 (2015-06-10). * arch/arm/src/stm32/stm32l15xxx_rcc.c: STM322 F15x stm32_stdclockconfig() was calling stm32_pw_setvos() which accessed PWR_CR via an inactive APB From Juha Niskaneni (2015-06-11). * fs/mount: Add the ability to mount a file system on top of en existing node in the psuedo-file system (2015-06-11). * arch/arm/src/sam34/sam_clockconfig.c: Add default loop optimization if EEFC_FMR is available in the configuration (i.e., for SAM4S and 4E). From Marco Aurélio da Cruz (2015-06-11). * include/time.h and libc/time: Add asctime(), asctime_r(), ctime(), and ctime_r() (2015-06-12). * include/ and arch/: Clean up and review of header files for conformance to standards (2015-06-12). * arch/arm/src/samdl: Add build framework for SAML21 DMA support. Nothing there yet except for skeletal logic taken from SAM3/4 (2015-06-12). * include/pthread.h and nuttx/sched/pthread: Use -1 instead of 0 as PID for unclaimed mutexes. From Juha Niskanen (2015-06-16). * sched/pthread: Implement pthread_mutex_trylock() for recursive mutexes. From Juha Niskanen (2015-06-16). * libc/unistd/lib_getopt.c: Uninitialized variable can cause hardfault from getopt if required argument is missing. From George McWilliams (2015-06-18) * arch/arm/include/samdl and arch/arm/src/samdl: Add architecture support for the SAMD21 family (2015-06-19). * configs/samd21-xplained: Board configuration for the SAMD21 Xplained board (2015-06-21). * arch/arm/src/sam34/sam_lowputc.c: Back out an error introduced with commit 02c33f66c5a8be774034cd40e4125e9323c7b4d8. Causes an infinite loop in up_lowputc(). From Max Neklyudov (2015-06-22). * arch/arm/src/samv7/sam_lowput.c: Also back the bad change to sam_lowputc.c for SAMV7 platform (2015-06-22). * include/nuttx/fs/ioctl.h and power/relay.h: Add relay IOCTL definitions. From Max Neklyudov (2015-06-22). * sched/clock/clock_gettime.c: Use up_timer_gettime for CLOCK_MONOTONIC in tickless mode. From Max Neklyudov (2015-06-22). * crypto/ and SAM4CM: Add CFB and MAC AES modes. From Max Neklyudov (2015-06-22). * SAM4CM: Fix SUPC register definitions. From Max Neklyudov. Also removed conditional logic form non-SAM4CM parts (Gregory Nutt) (2015-06-22). * SAM3/4: Add a TWI driver for the SAM4CM. From Max Neklyudov (2015-06-22). * SAMV7 Xplained: In clock configuration, divider was set to 25 to get 25*12MHz=300MHz CPU clock. The correct multiplier is 24 because the calculation if (24+1)*12MHz. So the board was running at 312MHz. From Efim Monjak (2015-06-26). * NFS client: Fix prototype of unbind method. The function prototype was not updated for NFS after a recent change to the file system interface. From Manuel Sthn (2015-06-25). * Broke the NuttX GIT repository into several, smaller repositories. Eliminated the misc/ directory and the content under misc/Obsoleted and misc/sims (2015-06-27). * Removed the Documentation/ directory. Replaced with a GIT submodule that will bring in the new standalone Documentation directory (2015-06-29). * Removed the configs/ directory. Replaced with a GIT submodule that will bring in the new standalone boards directory (2015-06-29). * arch/arm/src/armv6-m/up_exception.S: Fix Cortex-M0 assembly error when the interrupt stack is enabled. From Alan Carvalho de Assis (2015-06-30). * arch/arm/src/armv6-m/up_assert.c: Port some per-process stack dumping logic from ARMv7-M to ARMv6-M. From Alan Carvalho de Assis (2015-06-30). * tools/testbuild.sh: Add a script that can be used to perform building testing for several board configurations (2015-06-30). * sched/pthread/pthread_create.c: Group binding needs to be cleared before sched_releasetcb(), as otherwise group_leave() will be called and group->tg_nmembers decremented or group being released. group_leave() should be called only after group_join() is called, not after group_bind(). From Jussi Kivilinna (2015-07-01). * arch/arm/src/sama5/sam_ehci.c: Fix some bad conditional compilation that left a function undefined if CONFIG_USBHOST_ASYNCH is not selected (2015-07-01). * arch/arm/src/common/up_vfork.c: Fix a Cortex-A compilation error when system calls are enabled in modes other than CONFIG_BUILD_KERNEL (2015-07-01) * include/nuttx/net/netconfig.h: Fix some backward compilation that was emitting #error in the wrong condition when SLIP was enabled (2015-07-01). * drivers/net/slip.c: Fix a missed name change when many of network interface names changed sometime back but were apparently never updated for SLIP (2015-07-01). * drivers/input/stmpe811_base.c: In stmpe811_instanciate() when CONFIG_STMPE811_MULTIPLE is enabled, and the call to stmpe811_checkid() fails, then the linked device list is not restored to its previous state. From Sebastien Lorquet (2015-07-02). * sched/sched/sched_waitpid.c: Implement WNOHANG for waitpid() only and for the case of CONFIG_SCHED_HAVE_PARENT not selected. From Max Neklyudov (2015-07-02). * arch/sim/src/up_head.S: Implement board_power_off() for the simulation platform (2015-07-04). * libc/unistd/lib_gethostname.c: Add support for sethostname() (2015-07-05). * libc/net: Add support for gethostbyname() and gethostbyaddr(). Also support included for the non-standard gethostbyname_r() and gethostbyaddr_r() (2015-07-08). * drivers/ioexpander and include/nuttx/ioexpander: This commit adds: - headers in nuttx/ioexpander to define the "generic" ioexpander framework - files in drivers/ioexpander for the implementation of the NXP PCA9555 framework - bindings in drivers/Kconfig and drivers/Makefile From Sebastien Lorquet * arch/arm/src/lpc43xx/chip/lpc4310203050_pinconfig.h: Correct some LPC4350 GPIO pin configurations. From Alessandro Temil (2015-07-09). * mm/umm_heap, include/nuttx/kmalloc.h, userspace.h, mm/mm.h, and all configurations that support protected mode: Redesigned how the user space heap is accessed from the kernel code in protected mode. It used to call memory management functions in user space via function pointers in the userspace interface. That is inefficient because the first thing that those memory management functions do is to trap back into the kernel to get the current PID. Worse, that operation can be fatal is certain fragile situations such as when a task is exiting. The solution is to remove all of the memory management function calls from the interface. Instead, the interface exports the users pace heap structure and then kernel size implementations of those memory management functions will operate on the userspace heap structure. This avoids the unnecessary system calls and, more importantly, failures do to freeing memory when a test exits (2015-07-10). * libc/netdb: Move netdb functions from lib/net to lib/netdb. Move the DNS client logic from apps/netutils/dnscient to libc/netdb. Add support to gethostbyname() so that it will attempt a DNS host lookup before consulting the host table (if so enabled) (2015-07-10). * arch/arm/src/samdl/chip/saml_usb.h: Several fixes to register definitions and types. From Janne Rosberg (2015-07-10). * include/nuttx/net/ and libc/netdb: Repartitioning of DNS client logic in preparation for IPv6 support (2015-07-12): - Rename include/nuttx/net/dnsclient.h to dns.h - Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h - Global standard DNS definitions from libc/netdb/dns_soccket.c to dns.h - Eliminate dns_gethostip(). This is now an internal part of gethostbyname() - Eliminate interface dns_whois(). Not needed in this new context. * include/nuttx/net/ and libc/netdb: Modifications to DNS client logic and to dns_get/setserver() interfaces to support DNS clients at IPv6 addresses (still no support for resolution to IPv6 addresses) (2015-07-12). * include/nuttx/net/ and libc/netdb: Implement the low-level network DNS packet protocol to request and receive IPv6 address mappings (2015-07-12). * libc/netdb: Add a default value for DNS server IP address. Make sure that the IP address has been initialized before permitting DNS queries (2015-07-13). * libc/netdb: Add support for a DNS host name resolution cache. This can save a lot of DNS name server lookups (but might also have the negative consequence of using stale IP address mappings (2015-07-13). * graphics/, libnx/, and include/nuttx/nx: Implement anti-aliasing in order to clean the drawing of all edges (2015-07-14). * drivers/lcd/ and include/nuttx/lcd: Modify the SSD1306 LCD driver to support either the SPI or I2C interface.

This is a work in progress and will be a while before it is fully functional (2015-07-16). * arch/../up_etherstub.c, arch/../up_initialize, and other files: Add CONFIG_NETDEV_LATEINIT that can be used to suppress calls to up_netinitialize() from early in initialization (2015-07-17). * arch/arm/src/stm32: Extend STM32 Ethernet operating frequency to 180MHz. From Sebastien Lorquet (2015-07-17). * STM32 F7 Discovery: Basic NSH configuration is functional with a serial console. I-/D-Caches and DTCM have been enabled. The delay loop has been calibrated -- very fast (2015-07-19). * drivers/sensor and include/nuttx/sensors: Add support to Bosch BMP180 barometer. From Alan Carvalho de Assis (2015-07-20). * configs/stm32f4discovery/: Add support to BMP180 driver on the STM32F4Discovery.

From Max Neklyudov (2015-07-21). * arch/arm/src/stm32 and include/stm32: Add support for the STMicro STM32 F446. From David Sidrane (2015-07-22). * include/nuttx/sched.h, sched/, and fs/procfs: Increase the size of the scheduling policy field from 1 to 2 bits to allow additional, planned scheduling policies (2015-07-23). * pthread_create: Fix an (unlikely) error in fallback value in the event of a failure (which should never occur) (2015-07-23). * include/, sched/, and libc/: Add support for sporadic scheduling parameters in struct sched_param, posix_spawnattr_t, and pthread_attr_t. Update all user interfaces to pass sporadic scheduling parameters. (2015-07-23). * sched/: Separate the round-robin logic into a separate file so that it is symmetric with the sporadic stuff. Integrate the sporadic scheduler into the time tick interrupt handling and into the tickless operation (2015-07-24). * arch/arm/src/moxart/: Add support for MoxaRT SoC found in the most Moxa serial converters such as NP51x0, NP66xx, UC72xx. From Anton D. Kachalov (2015-07-29). * configs/moxa: Moxa NP51x0 series of 2-port advanced RS-232/422/485 serial device servers. From Anton D. Kachalov (2015-07-29). * drivers/net/ and include/nuttx/net: Add support for a Faraday * FTMAC100 Ethernet MAC Driver. From Anton D. Kachalov (2015-07-29). * 16550 UART Driver: Add a configuration option to indicate the THR empty bit is inverted. This is the case for the moxART SoC. Based comments from Anton D. Kachalov (2015-07-29). * STM32 F4: Add DMA support to the ADC driver for STM32 F4. From Max Kriegler (2015-07-30). * sem_tickwait(): Added this function for internal use within the OS. It is a non-standard but more efficient version of sem_timedwait() for use in higher performance device drivers (2015-08-01). * drivers/net/slip.c: Fix another compilation error (2015-08-02). * drivers/can.c include/nuttx/can.h, and fs/fs.h: Add CAN IOCTL command definitions to manage CAN message filtering (2015-08-05) * drivers/Kconfig and can.c: Add configuration to support DLC to byte conversions needed for CAN FD mode (2015-08-05). * arch/arm/src/samv7: Add an MCAN driver for the SAMV7 platform (2015-08-06). * drivers/sensors/lm92.c and include/nuttx/sensors/lm92.h: Add a driver for the LM92 temperature sensor. Contributed by Paul Alexander Patience (2015-08-06). * drivers/sensors/as5048b.c and include/nuttx/sensors/as5048b.h: Add support for an AS5048B rotary magnetic sensor. From Paul Alexander Patience (2015-08-07). * include/nuttx/spi/slave.h: Add a definition of an SPI slave interface (2015-08-08). * arch/arm/src/samv7: Add the framework for an SPI slave driver. This driver has a lot of missing logic on initial commit (2015-08-09). * arch/arm/src/samv7: Basic, no-DMA SPI slave driver is in place (2015-08-10). * fs/vfs/epoll.c and include/sys/epoll.h: Add a very simple epoll layer just around poll calls. To satisfy build app requirements. From Anton D. Kachalov (2015-08-10). * drivers/mtd/ramtron.c: Update to include supportf for newer RAMTRON parts.

From Paul Alexander Patience (2015-08-11). * net/udp: Add support for send() for connected UDP sockets (2015-08-11). * drivers/sensors/ms5805.c and include/nuttx/sensors/ms5805.h: Add support for an MS5805 altimeter. From Paul Alexander Patience (2015-08-12). 7.12 2015-10-01 Gregory Nutt * fs/vfs/fs_poll.c: Use sem_tickwait() instead of sem_timedwait() From Macs Neklyudov (2015-08-13). * fs/vfs/fs_poll.c: If we fail to setup the poll for any file descriptor, for any reason, set the POLLERR bit (2015-08-13). * libc/stdlib: Add support for div() to the C library. From OrbitalFox (2015-08-14). * libc/stdlib: Might as well add ldiv() and lldiv() to since these are equivalent to div() with long and long long types, respectively, instead of int (2015-08-14). * include/signal.h and files that include it: Add si_errno to siginfo_t (2015-08-14). * drivers/sensors/mx58xx.c and include/nuttx/sensors/ms58xx.h: Generalize the MS5805 altimeter driver to support other family members and rename to ms58xx.

From Paul Alexander Patience (2015-08-17). * include/nuttx/can.h and all CAN drivers: Add an error indication bit to the CAN message report. This indication must then be cleared in all existing drivers. More to come (2015-08-18). * arch/arm/src/lpc17/lpc17_irq.c: Set NVIC vector address so that code can execute with a bootloader or can execute from RAM. From Pavel Pisa (2015-08-20). * All ARMV7-M IRQ setup: Always set the NVIC vector table address unconditionally. This is needed in cases where the code is running with a bootload and when the code is running from RAM. It is also needed by the logic of up_ramvec_initialize() which gets the vector base address from the NVIC. Suggested by Pavel Pisa (2015-08-21). * SAMV7 USBHS DCD: The device controller driver is (finally) functional (2015-08-21). * recvfrom(): Correct wait for new data when NET_UDP_READAHEAD is enabled. Fix size accounting when recvfrom_udpreadahead() sets state.rf_recvlen == -1. I have not checked if data are accumulated to the right position in the buffer however. From Pavel Pisa (2015-08-21). * sched/wdog/wd_create.c: Correct a counting error in the number of available watchdog timers. When the number of free timers is low, the counter could be incremented below zero (2015-08-21). * arch/arm/src/stm32: Add OTG support for STM32F44x. From David Sidrane (2015-08-21). * arch/arm/src/lpc17: Actually implement options to use external SDRAM and or SRAM for the heap. From Pavel Pisa (2015-08-21). * gethostbyname(): correct returned address format when DNS is used. The hostent.h_addr_list should point to raw in_addr or in6_addr as defined in the standard. Original implementation used that for numeric addresses but for DNS lookup returned pointer to whole sockaddr_in or sockaddr_in6. From Pavel Pisa (2015-08-21). * tools/mksymtab: declare g_symtab array as const to occupy RO section (Flash). From Pavel Pisa (2015-08-23). * libc/libc.csv and syscalls/syscalls.csv: Define some symbol export conditions, correct errno and add sleep and usleep. From Pavel Pisa (2015-08-23). * net/ and include/nuttx/net: Remove references to PPP as a link layer protocol (2015-08-24). * net/, drivers/net, and include/net: Add definitions to support a local loopback device and link layer (2015-08-24). * libc/netdb, net/loopback, include/nuttx/net: Add NetDB support for the local loopback device (2015-08-24). * drivers/net/loopback.c: Add basic prototype of a local loopback device (2015-08-24). * networking: Correct return value from psock_tcp_accept(). From SaeHie Park (2015-08-25). * drivers/mtd/s25fl1.c: Add a driver for ST25L1*K QuadSPI parts (2015-08-25). * include/nuttx/spi/qspi.h: Develop a new interface for QSPI, at least the way that QSPI is implemented on the SAMV71. Originally planned to use the SPI interface, but it is just now compatible with the SAMV71 QSPI hardware (2015-08-25). * drivers/rwbuffer.c: Fix some logic errors. From Dmitry Nikolaev via Juha Niskanen (2015-08-26). * net/socket and net/tcp: Fix a problem in when there are multiple network devices. Polls were being sent to all TCP sockets before. This is not good because it means that packets may sometimes be sent out on the wrong device. That is inefficient because it will cause retransmissions and bad performance. But, worse, when one of the devices is not Ethernet, it will have a different MSS and, as a result, incorrect data transfers can cause crashes. The fix is to lock into a single device once the MSS is locked locked down (2015-08-27). * drivers/lcd and include/nuttx/lcd: Add SSD1351 OLED controller support. Contributed by Paul Alexander Patience (2015-08-28). * include/nuttx/mtd/mtd.h: Move MTD ioctl command definitions from include/nuttx/fs/fs.h to include/nuttx/mtd.h. Add ioctl commands to protect and unprotect memory (2015-08-29). * binfmt/builtin.c: Fix a memory leak: File was not being closed. From Bruno Herrera (2015-08-30). * fs/romfs: One allocation was not being freed if there was a subsequent failure to allocation I/O buffers resulting in a memory leak on certain error conditions. From Bruno Herrera (2015-08-30). * arch/arm/src/up_internal.h and several ARM Make.defs files: In the original implementation, !defined(CONFIG_ARMV7M_CMNVECTOR) was a sufficient test to determine if lazy floating point register saving was being used. But recents changes added common lazy register as well so now that test must be (!defined(CONFIG_ARMV7M_CMNVECTOR) || defined(CONFIG_ARMV7M_LAZYFPU)) (2015-08-31). * arch/arm/include/sama5 and src/sama5: Add basic chip description, configuration support and interrupt definitions for the SAMA5D2 (2015-08-31). * LPC43xx: Fix NVIC_SYSH_PRIORITY_STEP define. From Ilya Averyanov (2015-09-01). * LPC43xx: Fix missing #define in eeprom. From Ilya Averyanov (2015-09-01). * libc/math/lib_asin.c: The function did not convert for some input values. Asin did not convert for values which do not belong to the domain of the function. But aside of that the function also did not converge for some allowed values. I achieved a conversion of the function by reducing the DBL_EPSION and by checking if the input value is in the domain of the function. This is a fix for the problem but the function should always terminate after a given number of iterations. From Stefan Kolb (2015-09-01). * arch/arm/src/lpc43xx/lpc43_spi.c: Fix SPI driver. From Ilya Averyanov (2015-09-02). * arch/arm/src/lpc43xx/lpc43_ethernet.c: Add Ethernet support. From Ilya Averyanov (2015-09-02). * net/tcp: The logic that binds a specific network device to a connection was faulty for the case of multiple network devices. On bind(), the local address should be used to associate a device with the connection (if the local address is not INADDR_ANY); On connect(), the remote address should be used (in case the local address is INADDR_ANY). On accept(), it does not matter but the remote address is the one guaranteed to be available (2015-09-02). * configs/Board.mk and configs/*/src/Makefile: Simplify configs/ Makefiles by combining common logic into a new Board.mk Makefile fragment. From Paul Alexander Patience (2015-09-04). * configs/sama5d2-xult: Add a very basic configuration for the SAMAD2 Xplained Ultra board. This configuration is incomplete and only intended to support the initial board bring-up (2015-09-05). * up_initialize() all architectures: Automatically initialize all the TUN device if it is in the configuration (2015-09-06). * Change all references from avsprintf to vasprintf. From Sebastien Lorquet (2015-09-07). * net/tcp: Fix unbuffered send compilation error when Ethernet is not enabled. From Alan Cavalho de Assis (2015-09-07). * LPC31 and SAMA5D EHCI: Fix qh_ioccheck to move bp to next QH. From Ilya Averyanov (2015-09-07). * LPC31 and SAMA5D EHCI: Performance improvement: Do not disable the asynchronous queue when adding a new QH structure. From Ilya Averyanov (2015-09-07). * arch/arm/src/sama5: Separate memory mapping tables for SAMA5D2, 3, and 4 (2015-09-08). * libc/net/lib_shutdown.c: Add an empty implementation of the standard shutdown function. This provides only the framework for the shutdown function; the internal logic is not included (2015-09-09). * configs/nucleo-f303re: Support for the STMicro Nucleo F303RE board from Paul Alexander Patience (2015-09-10). * arch/arm/src/lpc43xx/lpc43_ehci.c and .h: LPC43xx EHCI driver from Ilya Averyanov (2015-09-10). * ARMv7-M, all "lazy" interrupt stack logic. Assembly instruction that fetches the saved value is incorrect; replace with more traditional push and pop. This is an important fix. Noted by Stefan Kolb (2015-09-14). * All ARMV7-M: Force 8-byte stack alignment when calling from assembly to C to interrupt handling (2015-09-15). * drivers/power/battery_gauge.c and include/nuttx/power/battery_gauge.h: battery.c/h renamed to batter_gauge.c/.h since it really only implements a battery fuel gauge. From Alan Carvalho de Assis (2015-09-19). * drivers/power/battery_charger.c and include/nuttx/power/batter_charger.h: Add a new framework to support a batter charger interface. From Alan Carvalho de Assis (2015-09-19). * drivers/power/bq2425x.c and .h: Battery Charger: Add BQ24250 driver. From Alan Carvalho de Assis (2015-09-20). * fs/mqueue/mq_open.c: When message queue is opened, inode_reserve() leaves the reference count at zero. mq_open() logic must assure that the reference count of the newly created inode is one (2015-09-23). * arch/sim/src/Kconfig, Makefile, up_setjmp64.S: Modern Cygwin X86_64 machines follow the Microsoft ABI for parameter passing. The older, Linux System 5 ABI will not work on X86_64-based Cygwin machines. Also, the newer Cygwin tool chains do nor pre-pend symbol names with the underscore character. With these changes the simulator agains works with the newer Cygwin64 platform (2015-09-24). * arch/arm/src/lpc43xx: Extensive I2C and clocking updates from Lok Tep (2015-09-29). * configs/lpc4370-link2: Support for the NXP LPC4370-Link2 development board from Lok Tep (2015-09-29). * configs/nucleo-f303re: Add SSD1351 SPI 4-wire interface. From Paul Alexander Patience (2015-09-29). * arch/arm/src/armv7-m/up_schedulesigaction.c: Fix logic that determines if there is a pending signal action before scheduling the next signal action. Both the test and the scheduling action need to be atomic (2015-09-30). * sched/wqueue/kwork_queue.c and libc/wqueue/work_queue.c: Logic that sets the queued indication and the logic that does the actual queuing must be atomic (2015-09-20). 7.13 2015-12-05 Gregory Nutt * libc/stdlib/lib_bsearch.c and include/stdlib.h: Add the bsearch() function from NetBSD (2015-10-02). * libc/stdlib/lib_qsort.c and include/stdlib.h: Make coding style more conformant, take description from OpenGroup.org, rename formal parameters to match names used on OpenGroup.org (2015-10-02). * drivers/lcd/st7565.c: Extend to include support for the ERC12864-3. From Pierre-noel Bouteville (2015-10-07). * fs/tmpfs: Created a directory that will eventually hold a trivial temporary RAM file file system (2015-10-0i8). * tools/: Add crappy style checking tool nxstyle.c.

From Max Kriegleder (2015-10-9). * fs/tmpfs: TMPFS file system is code complete and bascially functional although it has not been heavily tested (2015-10-9). * drivers/input/button_upper.c and include/nuttx/input/buttons.h: Add a driver to support application access to board buttons (2015-10-12). * drivers/input/button_lower.c: Add a generic lower half button driver. This lower half driver is only usable in a limited number of situations, but can still serve as a module for the lower half button driver. (2015-10-13). * drivers/sensors/zerocross.c and include/nuttx/sensors/zerocross.h: Add Zero Cross device driver support. From Alan Carvalho de Assis (2015-10-13). * configs/stm32f4discovery/src/stm32_zerocross.c: Add low level support for the Zero Cross driver for the STM32F4-Discovery.

From Alan Carvalho de Assis (2015-10-18). * configs/stm32f4discovery/src: Add board config to support MAX6675. From Alan Carvalho de Assis (2015-10-18). * arch/arm/src/samv7/sam_lowputc.c: Reconfigure System I/O when using USART1. From Frank Benkert (2015-10-20). * fs/semaphore: Named semaphores: Bad cast in sem_close(). Fixed by reordering fields of struct nsem_inode_s so that the cast will work (2015-10-22). * Many files: Rename board_led_* functions to board_autoled_* functions. This makes room in the namespace to handler user LED functions (2015-11-01). * Many files: Standardize naming of the user LED interface functions. The new user LED interface functions are now prototyped in only in include/nuttx/board.h and have name like board_userled_* (2015-11-01). * drivers/leds/usersled_upper.c and include/leds/usersled.h: Add a generic character driver that may be used by applications to write to board LEDs (2015-11-01). * drivers/leds/usersled_lower.c: Add a generic lower-half user LED driver that may be used by any board that supports the standard board user LED interfaces (2015-11-01). * sched/clock: Fix error in clock_timespec_subtract(). Found by Lok (2015-11-03). * drivers/can.c and include/nuttx/can.h: Fix a problem in the CAN upper-half driver that occurs only for CAN hardware that support a H/W FIFO of outgoing CAN messages. In this case, there can be a hang condition if both the H/W and S/W FIFOs are both full. In that case, there may be no event to awaken the upper half driver. Add a new (conditional) CAN upper half interface called can_txready() that can be used by the lower half driver to avoid this hang condition (2015-11-03). * arch/arm/src/samv7: Add a call to can_txready() to the MCAN driver (2015-11-03). * arch/arm/src/samv7: Add MPU and protected build support (2015-11-06). * arch/arm/src/samv7: The QSPI FLASH driver is now functional. This driver operates in the memory-mapped, Serial Memory Mode (SMM) (2015-11-07). * drivers/bch: Block-to-character (BCH) driver should forward ioctl() calls to the contained block driver (2015-11-09). * arch/arm/samv7/sam_qspi.c: The QuadSPI driver is now functional (2015-11-10). * drivers/mtd/s25fl1.c: The S25FL1xx QuadSPI FLASH driver is now functional (2015-10-11). * arch/arm/samv7: Add an on-chip FLASH driver (2015-11-12). * drivers/mtd/mtd_progmem.c: Add an upper half MTD device that can use the interfaces defined in included/nuttx/progmem.h to provide a standard MTD interface (2015-11-12). * drivers/serial/serial.c, serialirq.c and include/nuttx/serial/serial.h: Implement high level DMA infrastructure for serial devices. From Max Neklyudov (2015-11-12). * arch/arm/src/samv7 and arch/arm/include/samv7: Add support for the SAME70 family of chips (2015-11-14). * configs/stm32f429i-disco: configs/stm32f429i-disco/src/stm32_nsh.c file calculated partition boundries based on page block sizes but mtd_partition() is expecting calculations based on erase block size. From Alan Carvalho de Assis (2015-11-16). * Move rivers/wireless/cc3000/security.c to crypto/aes.c; move include/nuttx/wireless/cc3000/security.h to include/nuttx/crypto/aes.h (2015-11-16). * drivers/mtd/at24xx.c: Add support for multiple AT24xx EEPROM parts, each with unique I2C addresses, but otherwise identical (2015-11-17). * drivers/timers/ds3231.c: Add support for the DS3231 I2C RTC. Untested on the initial commit (2015-11-17). * arch/arm/src/stm32/stm32_tim_lowerhalf.c: Add a compatible lower-half timer driver for use with drivers/timers/timer.c.

Logical sectors 1 and 2 were simply not being allocated and then the read_sector and write_sector routines were failing. From Ken Pettit (2015-11-18). * drivers/timers/ds3231.c: Untested support for DS1302 and DS3232. Also definitions for the DS3234, but that is an unsupported SPI RTC (2015-11-19). * drivers/mtd/w25.c: Add support for byte write mode. From Ken Pettit (2015-11-20). * drivers/timers/pcf85263.c and include/nuttx/times/pcf85263.h: Add a driver for the NXP PCF85263 I2C RTC. Untested on initial commit (2015-11-20). * fs/driver/fs_blockproxy.c: Add logic to create a temporary char driver using drivers/bch to mediate character oriented accessed to a block driver (2015-11-21). * fs/vfs/open.c: If the use attempts to open a block driver, use block_proxy() to insert a character driver conversion layer in front of the block driver (2015-11-21). * libc/stdio/lib_freopen.c and include/stdio.h: Add support for freopen() (2015-11-22). * include/sys/types.h and include/nuttx/mm.h: When building on a 64-bit machine, the size of size_t should be 64-bits. In general, I believe that sizeof(size_t) should be the same as sizeof(uinptr_t). mmsize_t should always be 32-bits in any event. The last change to stddef has been backed out. With these changes, the simulator builds without * fs/hostfs and arch/sim/src: Add a special file system for use with simulator that supports access to the host file system from the simulation. From Ken Pettit (2015-11-25). * libc/time/lib_strftime.c: Add day-of-week support. (2015-11-25). * drivers/lcd/ili9432.c: Fixed errors in orientation. Portrait, RPortrait, and RLandscript should work correly now. They were displayed mirrored. From Marco Krahl (2015-11-25). * drivers/mtd/mtd/mtd_procfs/c and include/nuttx/mtd/mtd.h: Add an interface to un-register an MTD procfs entry. From Ken Pettit (2015-11-25). * drivers/mtd/filemtd.c: A new MTD conversion layer that will convert a regular file (or driver file) to an MTD device. This is useful for testing on the simulation using the hostfs. From Ken Pettit (2015-11-25). * drivers/loop: Add a loop character device. losetup() and loteardown() should not be called directory from applications. Rather, these functions are now available as IOCTL commands to the loop driver (2015-11-25). * include/nuttx/net/netdev.h and several Ethernet drivers in arch/: Most network drivers do not support statistics. Those that do only support them when DEBUG is enabled. Each driver collects an architecture specific set of statistics and there is no mechanism in place to view those statistics. Thus, the driver feature was mostly useless. This change standardizes the driver statistics and puts the definition in the common network device structure defined in netdev.h where they can be accessed by network applications. All Ethernet drivers that collect statistics have been adapted to use these common statistics (2015-11-26). * net/net_procfs.c: Add basic support for networking entries in the procfs (2015-11-27). * mtd/filemtd.c and smart.c: Add support for a /dev/smart loop device. From Ken Pettit (2015-11-28). * sched/pthread/: CRITICAL BUGFIX: Logic was wiping out the indication that of the type of a pthread. Hence, it could be confused as a task. Found because this was causing a crash when /proc/nnn/cmdline was printed (2015-11-29). * configs/same70-xplained/nsh: The NSH configuration now seems fully functional: serial console, LEDs, buttons, SDRAM, and HSMCI SD card (2015-11-30). * configs/same70-xplained/netnsh: Added and verified a network-enabled NSH configuration for the SAME70-Xplained board (2015-11-20). * net/: Remove CONFIG_NET_PINGADDRCONF. This was a uIP way of assigning IP addresses, but is not standard and not a appropriate feature in general (2015-12-01). * fs/procfs: The procfs file system can now be configured so that it supports a runtime registration of procfs entries with CONFIG_FS_PROCFS_REGISTER=y (2015-12-01). * arch/arm/src/stm32/stm32_ccm_procfs.c: Is no longer a part of the 'base' procfs entries and can now only be supported via run time registration with CONFIG_FS_PROCFS_REGISTER=y (2015-12-01). * arch/arm/src/samv7/sam_tc.c: Port the SAMA5 timer/counter driver to the SAMV7 (2015-12-02). * arm/arm/src/samv7/sam_tickless.c: Port the SAMA5/SAM4CM tickless logic to the SAMV7 (2015-12-02). * fs/semaphore: Named semaphores: Back out "fix" of 2015-10-22. It was correct before. The change of 2015-10-22 probably broke named semaphores (2015-12-02). * arch/arm/src/samv7: Bring programmable clock logic from SAMA5 into SAMV7 (2015-12-03). * arch/arm/src/samv7: Add PCK6 as an optional source for the timer/ counter clock (2015-12-04). * configs/samv7-xult/: If Tickless mode is selected then enable PCK6 as a timer/counter clock source (2015-12-04). 7.14 2016-01-28 Gregory Nutt * arch/arm/src/samv7: Port the TRNG driver from the SAMA5D3/4 to the SAMV7 (2015-12-06). * arch/arm/src/samv7: Port the WDT driver from the SAMA5D3/4 to the SAMV7 (2015-12-06). * arch/arm/src/samv7: Add an RSWDT driver (2015-12-06). * drivers/net/telnet.c: Move the Telnet driver from apps/netutils/telnetd to drivers/net. It is a driver a belongs in the OS. There are still some interface related issues, however (2015-12-07). * configs/: Update all configurations that use the Telnet daemon; those configurations now need to separately enable the Telnet drvier (2015-12-07). * drivers/net/telnet.c: Now works like the loop device. A new interface called telnet_initialize() registers a telnet session "factory" device at /dev/telnet. Via ioctl, the factory device can create instances of the telnet character devices at /dev/telnetN to support Telnet sessions (2015-12-07). * arch/arm/src/samv7: In USBHS device driver, fix check if zero length packet is needed (2015-12-08). * sched/pthread/: CRITICAL BUGFIX: Logic was wiping out the indication that of the type of a pthread. Hence, it could be confused as a task. Same problem as fixed on 2015-11-29, but in different location (2015-12-09). * sched/module: Add support for kernel modules. Initial commit is just the ELF module support with name changes (2015-12-10). * configs/samv71-xult/module: Add configuration for testing OS modules (2015-12-12). * sched/module: Add an implementation of rmmod() (2015-12-12). * sched/module and fs/procfs: Add some basic module procfs support (2015-12-12), * arch/arm/src/armv7-r: Add basic architecture support for the ARMv7-R processor family (2015-12-13). * drivers/led: Adds a driver for the PCA9635PW I2C LED driver IC which can be used to control the intensity of up to 16 LEDs. From Alexander Entinger (2015-12-15). * configs/launchxl-tms57004: Add basic board support for TI LaunchXL- TMS57004. Not much to see there yet (2015-12-15). * waitpid: CRITICAL BUGFIX. Add a reference count to prevent waitpid from using stale memory released by the waited-for task group (2015-12-22). * sys/time.h: Add timeradd(), timersub(), timerclear(), timerisset(), and timercmp() as macros. These are non-POSIX interfaces, but included in most BSD deriviatives, including Linux. From Manuel Sthn (2015-12-23). * arch/arm/src/stm32: Add timer input capture driver. From Pierre-Noel Bouteville (2015-12-24). * arch/avr: Add support for the Atmega2560. From Dimitry Kloper (2015-12-19). * configs/arduino-mega2560: Add support for the Arduino-Mega2560. From Dimitry Koper (2015-12-29). * sched/signal, sched/mqueue, sched/timer, include/signal.h, include/nuttx/signal, fs/aio, libc/aio, and probably other directories: Add support for the SIGEV_THREAD notification method in struct sigevent. This initial implementation will only work in the FLAT build. See the top-level TODO file for additional details (2015-12-30). * include/nuttx/compiler.h, include/nuttx/streams.h include/stdio.h include/syslog.h libc/stdio/, and libc/syslog: introduce support for Atmel toolchain in-flash strings. Atmel toolchain AVR compiler provides a transparent in-flash object support using __flash and __memx symbols. The former indicates to compiler that this is a flash- based object. The later used with pointer indicates that the referenced object may reside either in flash or in RAM. The compiler automatically makes 32-bit pointer with flag indicating whether referenced object is in flash or RAM and generates code to access either in run-time. Thus, any function that accepts __memx object can transparently work with RAM and flash objects. For platforms with a Harvard architecture and a very small RAM like AVR this allows to move all constant strings used in trace messages to flash in the instruction address space, releasing resources for other things. This change introduces IOBJ and IPTR type qualifiers. The 'I' indicates that the object may lie in instruction space on a Harvard architecture machine. For platforms that do not have __flash and __memx or similar symbols IOBJ and IPTR are empty, making the types equivalent to, for example, 'const char' and 'const char*'. For Atmel compiler these will become 'const __flash char' and 'const __memx char*'. All printf() functions and syslog() functions are changed so that the qualifier is used with the format parameter. From Dimitry Kloper (2016-01-05). * drivers/net/tun.c: Fix a compile time error in the TUN driver. From Vladimir Komendantskiy (2016-01-05). * Kconfig and include/debug.h: Add configuration to support an architecture-specific debug.h header file. From Dimitri Kloper (2016-01-09). * arch/avr/include/debug.h: Add an AVR-specific header file used when the AVR MEMX pointer is used.

The mkdeps executable generated from mkdeps.c is now that the only supported way to make dependencies (2016-01-09). * tools/mkdeps.c: Extended/fixed support for --winpath option. Dependencies now work under Cygwin with a native Windows toolchain (2016-01-10). * libc/netdb: Add support for the use of a DNS resolver file like /etc/resolv.conf (2016-01-14). * drivers/sensors/mcp9844.c and include/nuttx/sensors/mcp9844.h: Driver for the MCP9844 I2C digital temperature sensor with a selectable resolution. From Alexander Entinger (2016-01-15). * arch/arm/src/lpc43xx: Numerous LPC43 improvements to SPIFI and ADC from Lok Tep (2016-01-15). * configs/lpc4337-ws: Support for the WaveShare LPC4337-WS board. From Lok Tep (2016-01-15). * drivers/wireless/pn532.c: Add driver for the NXP pn532 NFC-chip. From Janne Rosberg and others at Offcode Ltd (2016-01-17). * drivers/sensors/lsm9ds1.c: Add driver for the STMicro LSM9DS1 chip. The LSM9DS1 is a system-in-package featuring a 3D digital linear acceleration sensor, a 3D digital angular rate sensor, and a 3D digital magnetic sensor. From Paul Alexander Patience (2016-01-17). * configs/olimex-stm32-h407: Added a port to the Olimex STM32 H407 board. This board features the STMicro STM32F407ZGT6 (144 pins). Contributed by Neil Hancock. (2016-01-18) * arch/arm/src/stm32/stm32_otgfs/hs/host.c: Fix some backward arguments to stm32_putreg(). Note by Hang Xu (2016-01-18). * include/nuttx/can.h and several CAN drivers: Add more extensive error reporting capaibility to the CAN interface. From Frank Benkert (2016-01-18). * libc/misc/lib_tea.h and include/nuttx/crypto/tea.h: Add an implementation of the Tiny Encryption Algorithm (2016-01-19). * sim/include: Now supports a customizable startup script with a read-only passwd file (2016-01-20). * sim/nsh: Uses the custom start up script, includes hooks for an MOTD message. (2016-01-20). * include/clock.h and lots of other files: If the 64-bit timer is selected, then use it whenever clock_systimer() is called rather then chopping the 64-bit timer down to 32-bits. Add a new type, systime_t to represent the 32- or 64-bit system timer (2016-01-21). * sched/clock/clock_systimespec.c: Fix an error in a time conversion (2016-01-21). * include/nuttx/clock.h: Get rid of clock_systimer32() and clock_systime64(). There is now only clock_systimer() (2016-01-21). * arch/arm/src/kinetis: Numerous updates to the Kinetis ENET driver. From Andrew Webster (2016-01-21). * arch/arm/src/kinetis: Add support for the MK60N512VLL100 Kinetis part. From Andrew Webster (2016-01-21). * net/tcp and net/iob: Numerous fixes, mostly relate to TCP and IOB buffering and race conditions. These were necessary for for the NuttX networking later to be stable in some stress testing. From Andrew Webster (2016-01-22). * include/spi/spi.h: Add an optional hwfeatures() method to the SPI interface (2016-01-23). * drivers/spi/Kconfig and many other files: Remove CONFIG_SPI_OWNBUS: Now its not just a good idea, its the law (2015-01-23). * include/nuttx/math32.h and libc/misc: Add some utilities to support 64-bit arithmetic operations for platforms that do not support long long types. Not yet used anywhere (2015-01-25). * arch/arm/src/samv7/chip: Add an AFEC header file (2016-01-25). * net/iob: iob_alloc_qentry() has the same issues as did iob_alloc() fixed on 2016-01-23. (2016-01-26). * drivers/usbhost/hid_parser.c: Wrong size used in memcpy(). From Hang Xu (2016-01-25). * drivers/ioexpander/pca9555.c: Fixed a bug in the function pca9555_setbit which occurs if someone tries to set one of the pins 8-15. The problem is that after the check if the pin is greater than 7 the variable addr is incremented and used in the Call I2C_WRITEREAD. But later in the call to the I2C_WRITE buf[0] is used as address but this address is not incremented as it should be. Note address does mean the address to the register in the ioexpander and not the I2C address. From Stefan Kolb (2016-01-26). * drivers/ioexpander/pca9555: Convert to use I2C_TRANSFER vs. I2C_WRITEREAD, the former is thread safe while the latter is deprecated (2016-01-26). * drivers/i2c/i2c_writeread.c: Create a wrapper that uses I2C_TRANSFER to implement I2C_WRITEREAD functionality (2016-01-26). * I2C: Eliminate the I2C_WRITEREAD method (2016-01-26). * drivers/i2c/i2c_read.c and i2c_write.c: Convert to use I2C_TRANSFER vs. I2C_READ and I2C_WRITE which are not thread safe (2016-01-26). * SPI: Rename the STM32 up_spiinitialize() to stm32_spibus_initialize() (2016-01-26). * SPI: Rename the SAM up_spiinitialize() to sam_spibus_initialize() (2016-01-26). * SPI: Rename the Tiva up_spiinitialize() to tiva_spibus_intialize() (2016-01-26). * SPI: Rename the PIC32MX/MZ up_spiinitialize() to pic32mx/mz_spibus_intialize() (2016-01-26). * SPI: Rename EFM32's efm32_spi_initialize to efm32_spibus_initialize() for compatibility with these other changes (2016-01-26). * SPI: Rename the KL up_spiinitialize() to kl_spibus_intialize() (2016-01-26). * SPI: Rename the Kinetis up_spiinitialize() to kinetis_spibus_intialize() (2016-01-26). * SPI: Rename the LPC31xx up_spiinitialize() to lpc31_spibus_intialize(), Rename the LPC17xx lpc17_spiinitialize() to lpc31_spibus_intialize(), Rename the LPC43xx up_spiinitialize() to lpc43_spibus_intialize() (2016-01-26). * SPI: Rename the AVR up_spiinitialize() to avr_spibus_intialize(), Rename the LPC2148 up_spiinitialize() to lpc214x_spibus_intialize(), Rename the Calypso up_spiinitialize() to calypso_spibus_intialize(), Rename the ez80 up_spiinitialize() to ez80_spibus_intialize(), Rename the STR71xx up_spiinitialize() to str71_spibus_intialize(), Rename the i.MX1 up_spiinitialize() to imx_spibus_intialize(), Rename the LPC2378 up_spiinitialize() to lpc23_spibus_intialize(), Rename the M9S12 up_spiinitialize() to hcs12_spibus_intialize(), Rename the x86 up_spiinitialize() to i486_spibus_intialize(), Rename the z16f up_spiinitialize() to z16_spibus_intialize(). up_spiinitialize() has been completely eliminated. (2016-01-27). * fs/vfs/fs_poll.c: Fix handling of sem_tickwait() return value sem_tickwait() does not return an -1+errno, it returns a negated errno value. Noted by Freddie Chopin. 7.15 2016-03-27 Gregory Nutt * drivers/analog/ads1242.c and include/nuttx/analog/ads1242.h: Driver for the 24-Bit Differential Input ADC ADS1242 that communicates via SPI with a MCU. Reading the ADC conversion result as well as configuring the ADC, setting the input channel, etc. is implemented via ioctl calls. However, it does not yet implement the standard ADC interface. From Alexander Entinger (2016-01-29) * configs/board/src/xyz_cxxinitialize.c: Move C++ initialization logic out of the RTOS and into the application space, specifically to apps/platform/board, where it belongs (2016-01-29). * drivers/modem/u-blox.c and include/nuttx/drivers/u-blox.h: Add an upper half driver for the U-Blox Modem. From Vladimir Komendantskiy (2016-01-30). * arch/arm/src/lpc17xx: Backport lpc43xx I2C driver, replacing the lpc17xx I2C driver. This gives us the I2C_TRANSFER method (2016-01-30). * arch/arm/src/lpc11xx: Backport the lpc17xx I2C driver, replacing the lpc11xx I2C driver. This gives us the I2C_TRANSFER method (2016-01-30). * arch/arm/src/lpc2378: Backo the Lpc17xx I2C driver, replacing the lpc2378 I2C driver. This gives us the I2C_TRANSFER method (2016-01-30). * configs/u-blox-c027: Support for the u-blox GSM and GPS module evaluation board with NXP LPCExpresso LPC1768. The GSM module is one of LISA-C200, LISA-U200 or SARA-G350. The GPS module is one of MAX-M7 or MAX-M8. From Vladimir Komendantskiy (2016-01-31). * drivers/, arch/, include/, numerous files: Restructuring of the I2C interface necessary to eliminate some thread-safety issues inherent in the legacy I2C interface design. This effects the interface definition, all I2C clients, and all low-level I2C drivers. I have used caution, but I still expect a change of this magnitude to introduce some errors. Any bug reports of bug fixes will be much appreciated (2016-02-01). * drivers/i2c/i2c_driver.c: Add an I2C character drivers to support raw I2C data transfers for test applications (2016-02-02). * I2C_RESET: Eliminate up_i2creset(). It should not be a global function; Now it is an I2C interface method (2016-02-02). * I2C: Rename up_i2cinitialize and up_i2cuninitilize to follow the correct naming convention. These are not common interfaces used by the OS; these are MCU-specific interfaces used only be MCU-specific code. The the correct naming is xyz_i2cbus_initialize and xzy_i2cbus_uninitialize where xzy is the MCU mnemonic (2016-02-02). * Networking drivers that support CONFIG_NET_NOINTS: Fix a race condition that can cause the TX poll timer to stop running. From Manuel Stuhn (2016-02-03). * All Network drivers: Remove the hsec parameter from devif_timer(). We can get better timing accuracy without it (2016-02-03). * drivers/ioexpander/pca555.c: Add logic to make the PCA555 driver thread safe (2016-02-03). * sched/init/os_start.c and include/nuttx/init.h: Add a state variable that provides the current level of OS initialization. This is needed by some logic that may attempt to run early in the start-up sequence but cannot run if a sufficient level of initialization has not yet occurred (2016-02-05). * libc/syslog/lib_syslog.c: If syslog timestamping is enabled, don't try to get the time if the timer hardware has not yet been initialized (2016-02-05). * fs/procfs/fs_procfskmm.c: Add /proc/kmm entry that shows that state of the kernel heap. Only useful in PROTECTED and KERNEL build modes where there is a kernel heap (2016-02-06). * sched/ and arch/: Replace explicit access to the OS internal data structure g_readytorun() with the wrapper this_task() which hides the implementation and will permit such things as more scalable representations of task queues and SMP (2016-02-06). * include/nuttx/net/arp.h, include/nuttx/net/ioctl.h, net/netdev/netdev_ioctl.c, and ARP-related files: Add support for IOCTL commands to manage the ARP table (2016-02-08). * ARMv7-A, ARMv7-R, and ARMv7-A: Add test-and-set logic and definitions needed to supports spinlocks (2016-02-09). * include/nuttx/spinlock.h: Add basic definitions for spinlocks.

Currently crashes when CONFIG_SMP is enabled as expected (2016-02-10). * sched/sched.h and other files: Replace the bool 'prioritized' in the task list table with a uint8_t bit set so that additional attributes of a task list can be provided without adding more booleans (2016-10-11). * Everywhere: Replace irqsave() with enter_critical_section(); replace irqrestore() with leave_critical_section(). This is part of the onging development of SMP support (2016-02-13). * Conform to naming convention: Rename irqsave() to up_irq_save(); rename irqrestore() to up_irq_restore(). These should no longer be used. If your code still uses them, please switch to enter_critical_section() and leave_critical_section() (2016-02-14). * Also rename irqdisable() and irqenable() to up_irq_disable() and up_irq_enable() (2016-02-14). * sched/signal and include/nuttx/sched.h: Move the list of signal actions from the TCB to the group structure. Signal handlers are not per thread but, rather, per task group. I know, I preferred it the other way too, but this is more compliant with POSIX (2016-02-18). * fs/ procfs/fs_procfsproc.c: Add support for showing CPU if SMP is enabled (2016-02-19). * include/pthread.h, sched.h, sys/types.h and other files: Rename cpuset_t to cpu_set_t which is the type used in some non-standard Linux/GNU interfaces. Move definitions of cpu_set_t to include/sys/types.h. Add prototypes for sched_setaffinity(), sched_getaffinity(), pthread_attr_setaffinity_np(), pthread_attr_getaffinity_np(), pthread_setaffinity_np(), and pthread_getaffinity_np(). No implementation is yet in place (2016-02-19). * sched/sched_cpuselect.c, include/nuttx/sched.h, and other files. Add a CPU affinity set to the TCB if SMP is enabled and use this CPU set as a mask for determining which CPUs the thread may run on (2016-02-19). * libc/pthread, sched/pthread/pthread_start.c, and include/pthread.h: Add an affinity field to the attrributes to permit controlling which CPUs a pthread may run on.

This is sometimes needed by drivers in order to recover from error conditions (2016-03-05) * AT24xx driver: Correct missing address calculation logic. From Frank Benkert (2016-03-08). * arch/ renaming: current_regs renamed to g_current_regs in all architectures. For ARM which is slowly developing SMP capability, g_current_regs is now an array of dimension 1 in most case but of higher dimension of the architecuture supports multiple CPUs (2016-03-09). * MTD: Increase block size in mtd_geometry_s to 32-bits (2016-03-09). * include/nuttx/clock.h: Missing parenteses in MSEC2TICK macro can cause wrong calculations. From Stefan Kolb (2016-03-09). * Build system: Added a 'make olddefconfig' target that will refresh a .config file without interaction. tools/refesh.sh now has a --silent option so that it can be used in batch modes without human input (2016-03-09). * tools/testbuild.sh: .config files were not being updated because (a) kconfig-conf was being called in the wrong directory and (b) apps/Kconfig had not yet been created. Now uses 'make olddefconfig' (2016-03-09). * arch/arm/src/stm32l4 and include/stm32l4: Add support for the STM32L4 family. From Sebastien Lorquet (2016-03-10). * configs/nucleo-l476: Add support for the Nucleo-L476 board. From Sebastien Lorquet (2016-03-10). * sched/tls and include/nuttx/tls.h: Basic definitions needed to support thread local storage (TLS). Not used anywhere yet (and may not be used in the near future either) (2016-03-10). * sched/sched_note.c and include/nuttx/sched_note.c: Add a configuration option to buffer RTOS instrumentation data in an in-memory buffer (2016-03-17). * drivers/syslog/note_driver.c: Add a character driver that will allow an application to read buffered scheduler instrumentation data (2016-03-17). * arch/arm/src/samv7/sam_usbdevhs.c: The USB driver has had some issue that would occasionally cause loss of packets. Back last December, a fix was put in for this but the fix apparently worsens the problem; now causing hangs. The basic problem is that the number of busy banks (NBUSYBKS) status is not real time but is delayed. This was fixed; now when the DMA completes and NBUSYBKS > 0, the NBUSYBK is interrupt is enabled and the operations are deferred until NBUSYBKS is truly zero (2016-03-17). * net/tcp/tcp_timer.c: Fix some logic when there are multiple network interfaces. In this case, TCP timeout events can really only being processed when the poll from the correct device is received (2016-03-20). * sched/wqueue/kwork_signal.c: Fix logic to find an IDLE worker thread; the test for busy was backward. From Linfei Chen (2016-03-22). * include/sys/boardctl.h, configs/boardctl.c, and many configurations: Add boardctl() support that will permit applications to control USB devices (2016-03-25). * configs/stm32l476vg-disco: Add support for the STM32L476VG Discovery board. From Dave (2016-03-25). 7.16 2016-06-01 Gregory Nutt * PM: Add activity domain to all PM interfaces and driver callbacks. If CONFIG_PM_NDOMAINS == 1, then the legacy behavior is preserved. If CONFIG_PM_NDOMAINS > 1, then multiple PM domains are supported. This will allow separate control for certain power management groups. For example, a network can be shut down without affect an ongoing UI (and vice versa) (2016-03-27). * apps/configs/vsn: Removed the VSN configuration from the main NuttX repository. The VSN can still be found in the Obsoleted repository (along with a full explanation in the README file there) (2016-03-29). * arch/arm/src/armv7-m and stm32: Add support for the IAR toolchain for the limited case of the ARMv7-M architecture and the STM32 chip. From Aleksandr Vyhovanec (2016-04-02). * arch/arm/src/stm32/stm32f40xxx_rtc.c: Add a custom RTC driver. From Neil Hancock (2016-04-02). * include/nuttx/timer/rtc.h and drivers/timers/rtc.c: Simplify the RTC interface. The old interface was way to complex and was not fully implemented anywhere (2016-04-02). * Moved NuttX repository to https://bitbucket.org/nuttx/nuttx (2016-04-06). * arch/arm/src/armv7-m/iar: Convert more assembly language files for use with the IAR toolchain. From Kha Vo (2016-04-08) * Fix miscellaneous build issues for the IAR compiler. From Kha Vo (2016-04-08). * tools/ide_exporter.py: IDE exported Python script for use with the IAR toolchain. From Kha Vo (2016-04-08). * STM3220G-EVAL: Add support for both the IAR and uVision GCC IDEs From Kha Vo (2016-04-08). * STM32F429I Discovery: Add support for the uVision GCC IDE. From Kha Vo (2016-04-08). * libc/signal and include/signal.h: Rename sigset() to signal(). sigset() is the System V function; signal() is the obsoleted POSIX name. These seem to be equivalent. Neither are relevant in modern POSIX programming but the name signal() probably has the better credentials. sigset() is now relegated to a #define in signal.h that makes it equivalent to signal() (2016-04-10). * configs/nucleus2g: Removed the Nucleus2G configuration. There has not been any activity with the commercial board in a few years and it no longer appears to be available from the 2g-eng.com website. Since the board is commercial and no longer publicly available, it no longer qualifies for inclusion in the open source repositories. The code as of this data is still available in the Obsoleted repository at configs/nucleus2g (2016-04-12). * arch/arm/src/stm32l4: Fix the STM32L4 SPI driver. That SPI driver is quite different. They now handle frames of arbitrary size between 4 and 16 bits. It was broken before a new bit has to be set (RX fifo threshold) to handle <= 8-bit transactions. If not set, the default is 16-bit packed >=8-bit frames and the RXNE bit is never set (it is set when 16-bits are received). weird things as always. This also add 8-bit access routines to the data register, because a 16-bit access to the data register when the frame size is below 9 bits is interpreted as a packed dual frame exchange. Sebastien Lorquet (2016-04-13). * net/sockets/listen.c and accept.c and include/nuttx/net: Separate out psock_listen() and psock_accept() for internal OS usage (2016-04-14). * fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads. They must use SYSLOG for output and the low-level psock interfaces for network I/O. This saves a little memory which might be important for small footprint configurations (2015-04-14). * Framebuffer driver: Add a display number to each interface in order to support multiple display devices (2015-04-14). * drivers/wireless/nrf24l01.c: Fix backward calculation of relative frequency. Noted by Henry Zhang (2015-04-15). * drivers/sensors/h1750fvi.c: Add a character driver for Rohm Ambient Light Sensor BH1750FVI. From Alan Carvalho de Assis (2016-04-15). * configs/stm32f4discovery: Integrate BH1750FVI driver in the STM32F4Discovery board. From Alan Carvalho de Assis (2016-04-15). * drivers/mtd: Add MTD support for Micron N25Qxxx family of QSPI flash. From Dave dev@ziggurat29.com (2016-04-17). * arch/arm/src/stm32l: Add a QSPI driver. From Dave dev@ziggurat29.com (2016-04-18). * configs/stm32l476vb-disco: Add support for QSPI based N25Qxxx flash. From Dave dev@ziggurat29.com (2016-04-18). * graphics/vnc: Add support for a VNC server. This logic is code complete, but untested and so not ready for prime time (2016-04-18). * configs/samv71-xult/vnc: Add a configuration that will be used to verify VNC (also untested) (2016-04-18). * drivers/ioexpander: Fix an error in the PCA9555 driver: Under certain error conditions, interrupts were not being re-enabled. Sebastien Lorquet (2016-04-20). * arch/arm/src/stm32 and configs/stm32f429i-disco: Correct some bad commits that broke the LTDC display example. From Marco Krahl (2016-04-22). * configs/samv71-xult/vncwwm: Add a more complex NxWM configuration to support further VNC testing (particularly of VNC keyboard and mouse inputs). Initial configuration is not functional (2016-04-23). * arch/arm/src/stm32l4: Add support for QSPI DMA. From Dave dev@ziggurat29.com (2016-04-24). * configs/stm32l476vg-disco: Update stm32l4 disco board to reflect QSPI DMA support. From Dave dev@ziggurat29.com (2016-04-24). * arch/arm/src/stm32l4: Add configuration options to allow SRAM2 to be used for heap, or not at all, and to zero-initialize it on OS start, or not at all. From Dave dev@ziggurat29.com (2016-04-24). * drivers/mtd/smart.c: Return code of smart_scan not checked, can cause success result in failure case, leading to 'dev' pointer being invalid. From Dave dev@ziggurat29.com (2016-04-27). * arch/arm/src/stm32l4: Add support for QSPI memory mapped mode. From Dave dev@ziggurat29.com (2016-04-27). * configs/stm32l476vg-disco: Add board ioctls for allowing user application to cause QSPI memory mapped mode to be engaged and disengaged. Also partitioned QSPI flash for file system and other (eventually xip). From Dave dev@ziggurat29.com (2016-04-27). * fs/mount: Fix a backward debug assertion. Noted by David Sidrane (2016-04-29). * arch/arm/src/stm32l4: Add support for HSE and MSI clocks, and auto trim of MSI to LSE (needed for USB). From Dave dev@ziggurat29.com (2016-04-29). * arch/arm/src/stm32l4: Add support for unique id function to arch; modified board to support unique id boardctl. From Dave dev@ziggurat29.com (2016-05-03). * Makefile.unix and tools/mkexport.sh: Pass top-level make to the script to allow -j greater than 1. From David Sidrane (2016-05-04). * arch/arm/src/stm32, stm32f7, stm32l4: Fix typo in variable name in serial BREAK logic. Review other serial implementations for similar naming problems. (2016-05-05). * arch/arm/src/samv7: Fix typo in MATRIX register definitions. From Stefan Kolb (2016-05-06). * arch/arm/src/stm32l4: Problem with resetting backup domain clears clocking options set up before in *rcc.c use INITS flag to avoid magic reg value to detect power up reset state of RTC correct a problem clearing interrupt flags (they weren't) which prevented an alarm from ever being used more than once per reset cycle. From Dave dev@ziggurat29.com (2016-05-07). * arch/arm/src/tiva: Fix a bug of GPIO falling-edge interrupt for tiva. From Young (2016-05-07). * drivrs/mtd: Add a driver for SST26F spi/qspi flash devices (SPI mode only). From Sebastien Lorquet (2016-05-10). * Several Makefiles: Add .PHONY definitions to prevent 'clean up to date' message weirdness when 'make clean' is done with no .config or Make.defs file (2016-05-10). * include/nuttx/can.h and drivers/can.c: Improve CAN error reporting. From Frank Benkert (2016-05-11). * fs/Kconfig: Allow CONFIG_FS_WRITABLE to be manually selectable (2016-05-11). * Various file: Search for places where a stray semicolon following an if condition cause the if body to be executed unconditionally. Fixes in all SAM DMA logic, unionfs, OS signalling logic, * configs/nucleo-144: Basic port for the Nucleo-144 board with the STM32F746ZG MCU. From Kconstantin Berezenko (2015-05-12). * arch/arm-src/armv7-a: Complete re-design of logic to initialize each CPUn, n > 0, when CONFIG_SMP=y (2016-05-13). * arch/arm/src/imx6 and configs/sabre-6quad: The basic i.MX6 port is complete. This is a very minimal port at present and probably still has some as-of-yet-undiscovered issues (2016-05-17). * arch/*/Makefile: Add definitions that can be overrided to use GCC instead of LD in the final link. From Paul Alexander Patience (2016-05-18) . * arch/arm/src/stm32, stm32l4, and stm32f7 serial: Add support for compliant BSD-style breaks. From David Sidrane (2016-05-18). * enter/leave_critical_section() may attempt to access task lists before they have been initialized in the SMP configuration (2016-05-18). * configs/stm32f103-minimum: Add support for this minimual STM32F103CBT6 "blue" board. From Alan Carvalho de Assis (2016-05-18). * arch/arm/src/sam* Watchdogs: Rename up_wdginitialize() to something more appropriate for an internal, MCU-specific function (2016-05-18). * configs/*/src/*_watchdog.c: Remove all implementations of up_wdginitialize() which was only used by apps/examples/watchdog. That internal OS function is no longer called from application code. If you want to use the watchdog example, you will need to configure the watchdog driver by calling the appropriate, MCU-specific driver configuration function from your board initialization logic (2016-05-18). * arch/srm/src/stm32l4: Add CAN support for STM32L4. From Sebastien Lorquet (2016-05-19). * arch/arm/src/samv7: Adds a JTAG config and ERASE config to Kconfig to set the CCFG_SYSIO SYSIO Pins. From David Sidrane (2016-05-19). * arch/sim/src: Enhance networking support for the simulation under Linux. Includes updated support for Linux TUN/TAP, and the addition of support for Linux bridge devices. From Steve (2016-05-20). * configs/stm32f411e-disco: Add basic configuration for stm32f411e-disco board with STM32F411VE chip. From Konstantin Berezenko (2016-05-20). * i.MX6 Sabre-6Quad: Basic SMP NSH configuration is now working. But this is probably only because the SMP NSH case does not stress the logic. There are know outstanding SMP issues as noted in the Sabre-6Quad README.txt file (2016-05-22). * configs/sabre-6quad: Add an SMP configuration; Enable procfs in all configurations (2016-05-22). * include/nuttx/crypto/aes.h: Modifications to the crypto API needed for LPC43xx. From Alexander Vasiljev (2016-05-23). * arch/arm/src/lpc43xx: Add AES support. From Alexander Vasiljev (2016-05-24). * configs/*/src/tiva_timer.c: Tiva boards: Fix a naming collision, rename board-specific function from tiva_timer_initialize() to tiva_timer_configure() to remove conflict (2016-05-23). * arch/arm/src/sam*: Ensure that the TWIHS (i2c) hw get's its clock set when the sequence of sam_i2cbus_initialize(), sam_i2cbus_uninitialize(), then sam_i2cbus_initialize() or twi_reset() is called. I found this a while back in the stm32 family, so there may be more arch-es with this sort of bug. I suppose any driver that has the notion of "do not set the freq if it is already set" could be suspect. From David Sidrane (2016-05-23). * arch/arm/src/samv7: Add the up_systemreset interface to the samv7 arch. The approach is slightly different in that: 1) It enables ARCH_HAVE_RESET and allows the user to set if, and for how long, to drive External nRST signal. It also does not contain a default board_reset, as that really should be done in the config's src if CONFIG_BOARDCTL_RESET is defined. From David Sidrane (2016-05-23). * arch/arm/include/lpc43xx and src/lpc43xx: Adds definitions for the LPC4337jet100 chip. From Alexander Vasiljev (2016-05-24). * Many files: board_app_initialize() now accepts an argument that may be used to support initialization in different configurations (2016-05-24). * arch/arm/src/samv7: Remove disabling of whole USB on suspend of USBHS. This fix removes the disabling of the whole USB peripheral on suspend interrupt. Its enough to freeze the clock instead. When disabling the whole peripheral, the next wakeup-interrupt comes up with an disabled clocking. The unfreeze clock has no effect, because the master clock is disabled. This makes all registers, including the IDR unwriteable and the IRQ falls in an endless loop blocking the whole system. Furthermore the disabling of the peripheral clock prevents hotplugging or reconnecting the USB. From Frank Benkert (2015-05-25). * drivers/lcd: Add support for PCF8574 LCD Backpack driver. This driver supports an interface board that is based on the PCF8574 io expander and supports the HD44780-based (or compatible) LCD modules. There are a myriad of different vendors of such, but they are principally the same, save wiring and minor features like jumpers for I2C addresses. This driver supports known and unknown variants. From Dave (ziggurat29, 2013-6-26). * arch/arm/stm32: Add support for a custom 1-wire driver. The serial driver already supports a 1-wire interface, but this driver uses the same serial logic to implement a lower half driver much like the I2C lower half driver. From Aleksandr Vyhovanec (2015-05-25). * fs/: Add logic to detach a file structure from a file descriptor. This is for use only within the OS. It permits an open file or driver to be used across multiple threads (2016-05-26). * arch/arm/src/stm32l4: Get I2C working for STM32L4. From Dave (ziggurat29) (2016-05-25). * fs/ and include/nuttx/fs: Add logic to detach a file structure from a file descriptor. This is for use only within the OS. It permits an open file or driver to be used across multiple threads. (2016-05-26). * drivers/analog/adc.c, include/nuttx/analog/adc.h, and all ADC lower half drivers: No longer uses global adc_receive() call. Added a new bind() method to the ADC interface. Now the ADC upper half driver will register its receipt-of-data callback. This change allows the ADC lower half driver to be used with a differ ADC upper half (2016-05-26). * drivers/analog/ads1255.c: Must not do SPI access from interrupt handler. Use the worker thread instead. Must also lock the SPI bus before using it. (2015-05-26). * drivers/: Several SPI-based drivers modified. All drivers that use SPI must call SPI_LOCK and SPI_UNLOCK. This is not optional (2016-05-26). * drivers/sensors: Fix a bug in crc computation for ms583730. Implement POSIX read (2016-05-27). * arch/arm/src/samv7: This is a fix to a problem in the handling of the oneshot timer. Due to a wrong assumption concerning the behavior directly after the start of the timer/counter the function sam_oneshot_cancel(…) calculates the wrong remaining time. The code assumes that the counter register is zero directly after the start of the timer, but this is not true. To start the time/counter a software trigger is invoked, this trigger starts the timer/count and sets the counter register to zero, but the reset of the counter register is not performed instantly. According to the datasheet: "The counter can be reset by a trigger. In this case, the counter value passes to zero on the next valid edge of the selected clock." Thus the counter is set to zero between 0 and USEC_PER_TICK microseconds after the clock was started. In my fix I use the freerun count value to determine if at least one tick passed since the start of the timer and thus if the value of the oneshot counter is correct. I also tried to use the function up_timer_gettime(…) to achieve this but, at least if compiled with no optimization the problem vanishes without using the value of the function, the function call takes too long. Another problem treated in the fix is that if the oneshot timer/counter is canceled, we only know the remaining time with a precision of USEC_PER_TICK microseconds. This means the calculated remaining time is between 0 and USEC_PER_TICK microseconds too long. To fix this I subtract one tick if the calculated remaining time is greater than one tick and otherwise set the remaining time to zero. By doing so the measured times are much more precise as without it. From Stefan Kolb (2016-05-27). * arch/arm/src/sama5: Stefan Kolb's change to the SAMV7 Oneshot Timer should also be applied to the SAMA5 oneshot time since the drivers are identical (2016-05-27). * arch/arm/src/stm32l4: Add support for SPI 4 and 5 on stm32f411 chips. From Konstantin Berezenko (2016-05-27). * arch/arm/src/sam34: Stefan Kolb's change to the SAMV7 Oneshot Timer should also be applied to the SAM3/4 oneshot time since the drivers are identical (2016-05-29). * arch/arm/src/stm32: Allow to not use all channel in a lower part of PWM. From Pierre-noel Bouteville (2016-05-30). * libc/math: Add a NAN test on 'x' in asin function of lib_asin.c. Suggested by Pierre-noel Bouteville (2016-05-31). * arch/arm/src/stm32: Fix logic in F4 RTCC driver that prevent ALARM interrupt. From Neil Hancock (2016-05-31). * arch/arm/src/stm32: Fix STM32 ValueLine ADC IRQ number selection. From David Sidrane (2016-05-31). * arch/arm/src/samv7: Fix missing unlock of device in MCAN mcan_txempty(). From Frank Benkert (2016-06-01). 7.17 2016-07-25 Gregory Nutt * drivers/mtd/flash_eraseall.c: Removed. This is no longer used in the OS and is simply a wrapper around the MDIOC_BULKERASE IOCTL command. It used to be called (only) from apps/system/flash_eraseall, but that has been removed because it violated the OS/application interface -- by calling flash_eraseall(). The old code can be found in the Obsoleted' repository (and a revised version can be found at apps/fsutils/flash_eraseall) (2016-06-03). * arch/arm/src/stm32: STM32 Timer Driver: Change calculation of per- timer pre-scaler value. Add support for all timers (2016-6-03) * drivers/lcd: Correct conditional compilation in ST7565 driver. From Pierre-noel Bouteville (2016-6-03) * arch/arm/src/stm32: Correct conditional compilation in STM32 timer capture logic.

From v01d (phreakuencies) (2016-06-04) * arch/arm/src/kl and lpc11xx: rename xyz_lowputc to up_putc. Remove all references to up_lowputc, everywhere (2016-06-04). * configs/stm32f103-minimum: Add minnsh configuration. From Alan Carvalho de Assis (2016-06-04). * arch/arm/src/stm32: Add the up_getc() function to STM32 in order to support the minnsh configuration. From Alan Carvalho de Assis (2016-06-04). * include/sys/boardctl.h: Needs to be usable with C++ files (2016-06-05). * tools/tesbuild.sh will now build NxWM configurations (2016-06-05). * arch/arm/src/stm32: In PWM driver, just update duty if frequency is not changed and PSM started. This removeis glitch or blinking when only duty is frequently changed. From Pierre-noel Bouteville (2016-06-05). * arch/arm/src/kinetis: Add a USB device controller driver. Derived from the pic32mx usb driver, which uses the same usb controller. From kfazz (2016-06). * configs/teensy-3.x: Add USB support and a usbnsh configuration. From kfazz (2016-06). * arch/arm/src/stm32: Add support for the STM32F105R. From Konstantin Berezenko (2016-06-06). * include/signal.h: Change type of SIG_ERR, SIG_IGN, ... to _sa_handler_t. The type void does not work with the IAR toolchain. From Aleksandr Vyhovanec (2016-06-07). * configs/nucleo-144: Refactored configs/nucleo-144 sub-directories to support additional nucleo-144 board. Add support for the Nucleo-F767ZI board. From David Sidrane (2016-06-07). * arch/arm/src/stm32f7 and include/stm32f7: Added STM32F76xxx and STM32F77xx families.

From Marten Svanfeldt (2016-06-08). * drivers/mtd: Add a driver of IS25xP SPI flash devices. From Marten Svanfeldt (2016-06-09). * arch/arm/src/Kconfig and configs/teensy-3.x: Teensy clock fixes. The High Gain bit in MCG_C1 was preventing teensy from booting except after a programming session. The second change doesn't appear to change any functionality, but complies with restrictions in the k20 family reference manual on FEI -> FBE clock transiions. From kfazz (2016-06-09). * configs/*/include/board.h: Fix timer input clock definitions. From David Sidrane (2016-06-09). * Networking: In both IPv6 and IPv4 incoming logic: (1) Should check if the packet size is large enough before trying to access the packet length in the IP header. (2) In the comparison between the IP length and the full packet length, need to subtract the size of the link layer header before making the comparison or we will get false positives (i.e., the packet is really too small) (2016-06-09) * configs/: All configurations that have both CONFIG_NSH_LIBRARY=y and CONFIG_NET=y must now also have CONFIG_NSH_NETINIT=y (2016-06-09). * arch/arm/src/kinetis: Kinetis pwm support, based on kl_pwm driver. From kfazz (2016-06-09). * arch/srm/src/stm32: Fix compilation errors in debug mode of stm32_pwm.c. From Konstantin Berezenko (2016-06-09). * arch/arm/src/kinetis: Support up to 8 channels per timer. From kfazz (2016-06-09). * lib/: crc16: Fix error. From Paul Alexander Patience (2016-06-10). * lib/: Add crc64 support. From Paul Alexander Patience (2016-06-10). * arch/arm/src/kinetis: Added kl_dumpgpio functionality as kinetis_pindump. From kfazz (2016-06-10). * arch/arm/src/sam34: Fix some errors in AFEC header file. From OrbitalFox (2016-06-10). * arch/arm/include/stm32: Correct the can2 rx irq number for stm32f10xx chips. From Konstantin Berezenko (2016-06-10). * drivers/include/input: Button upper half driver: Add definitions needed for compilation with the poll() interface is not disabled (2016-06-11). * Kconfig/, include/debug.h, and many other files: (1) Debug features are now enabled separately from debug output. CONFIG_DEBUG is gone. It is replaced with CONFIG_DEBUG_FEATURES. (2) The macros dbg() and vdbg() have renamed as err() and info(), respectively. This also applies to all of the variants as well, lldbg(), llvdbg(), XXdbg(), XXvdbg(), XXlldbg(), and XXllvdbg(). (3) Add a new debug level, warn() (and all variants vwarn(), llwarn(), etc.). (4) Debug assertions can now be enabled separately from debug output. (5) You can now enable subsystem/device driver debug output at different output levels. For example, CONFIG_DEBUG_FS no longer enables file system debug output. It enables general file system debug logic and enables selection of CONFIG_DEBUG_FS_ERROR, CONFIG_DEBUG_FS_WARN, and CONFIG_DEBUG_FS_INFO (2016-06-12). * strtoul() and strtoull(): Fix errno settings required by function definition. Resolved Bitbucket Issue #1. From Sebastien Lorquet (2016-06-13) * arch/arm/src/stm32f7: Add SPI driver. DMA not yet supported. From David Sidrane (2016-06-14). * configs/nucleo-144: Add test for STM32 F7 SPI. From David Sidrane (2016-06-14). * alert(): New debug macro: alert(). This is high priority, unconditional output and is used to simplify and stanardize crash error reporting(2016-06-14). * arch/arm/src/tiva: Bug Fix in tiva_serial.c - UART5, UART6 and UART7 were not being configured as TTYS0 for printing over serial console. From Shirshak Sengupta (2016-06-14). * SAMV7: SPI: SPI-Freq. 40MHz; VARSELECT; hw-features This change adds the following improvements: - Increase the allowed SPI-Frequency from 20 to 40 MHz. - Correct and rename the "VARSELECT" option This option was included in the code as "CONFIG_SPI_VARSELECT" but nowhere defined in a Kconfig file. The change renames it to "CONFIG_SAMV7_SPI_VARSELECT" and corrects the implementation according the datasheet of Atmel. In short, this option switches the processor from "fixed peripheral selection" (single device) to "variable peripheral selection" (multiple devices on the bus). - Add a new Function to the interface to control the timing and delays of the chip according the ChipSelect lines. This function can control the delay between the assertion of the ChipSelect and the first bit, between the last bit and the de-assertion of the ChipSelect and between two ChipSelects. This is needed to tune the transfer according the specification of the connected devices. - Add three "hw-features" for the SAMV7, which controls the behavior of the ChipSelect: - force CS inactive after transfer: this forces a (short) de-assertion of the CS after a transfer, even if more data is available in time - force CS active after transfer: this forces the CS to stay active after a transfer, even if the chip runs out of data. Btw.: this is a prerequisit to make the LASTXFER bit working at all. - escape LASTXFER: this suppresses the LASTXFER bit at the end of the next transfer. The "escape"-Flag is reset automatically. From Frank Benkert (2016-06-14) * Many CONFIG_DEBUG_* options did not have matching macros defined in include/debug.h. Rather, there were various definitions scattered throughout the sourse tree. These were collected together and centralized with single macro definitions in include/debug.h (2016-06-15) * STM32F7: Add SPI, I2C, and ADC drivers. From Lok Tep (2016-06-15). * err(), warn(), info(), and alert() renamed to include leading '_'. This was done to avoid some naming collisions (2-06-16 * STM32: Move backup domain reset to to earlier in the initialization sequence (stm32_rcc.c() in order to avoid disabling LSE during RTC initialiation. From Alan Carvalho de Assis (2016-06-16). * SYSLOG: syslog() will now automatically redirect output to lowsyslog() if called from an interrupt handler (2016-06-16). * STM32: When configuring a GPIO via stm32_configgpio() the function will first set the mode to output and then set the initial state of the gpio later on. If you have an application with an externaly pulled-up pin, this would lead to a glitch on the line that may be dangerous in some applications (e.G. Reset Line for other chips, etc). This changes sets the output state before configuring the pin as an output. From Pascal Speck (2016-06-17). * STM32 F7: Apply Pascal Speck's GPIO STM32 change to STM32 L4 (2016-06-17). * STM32 L4: Apply Pascal Speck's GPIO STM32 change to STM32 L4. From Sebastien Lorquet (2016-06-17). * Review all uses of *err(). These macro family should indicate only error conditions. Convert *err() to either *info() or add ERROR:, depending on if an error is reported (2016-06-17). * STM32F7: Review, correct, and update I2C, SPI, and ADC drivers. From David Sidrane (2016-06-17). * LPC17 Ethernet: Needs to correctly ignore PHYID2 revision number when comparing PHY IDs (2016-06-18). * SYSLOG: Consolidate all SYSLOG logic in drivers/syslog. Add an abstraction layer that supports: (1) redirection of SYSLOG outpout. This is usually so that you can boot with one SYSLOG output but transition to another SYSLOG output when the OS has initialialized, (2) adds common serialization of interrupt output as a configuration option. Without this configuration setting, interrupt level output will be asynchronous. And (3) vsyslog is now a system call and is usable with other-than-FLAT builds (2016-06-19). * TCP Networking: While working with version 7.10 I discovered a problem in TCP stack that could be observed on high network load. Generally speaking, the problem is that RST flag is set in unnecessary case, in which between loss of some TCP packet and its proper retransmission, another packets had been successfully sent. The scenario is as follows: NuttX did not receive ACK for some sent packet, so it has been probably lost somewhere. But before its retransmission starts, NuttX is correctly issuing next TCP packets, with sequence numbers increasing properly. When the retransmission of previously lost packet finally succeeds, tcp_input receives the accumulated ACK value, which acknowledges also the packets sent in the meantime (i.e. between unsuccessful sending of lost packet and its proper retransmission). However, variable unackseq is still set to conn->isn + conn->sent, which is truth only if no further packets transmission occurred in the meantime. Because of incorrect (in such specific case) unackseq value, few lines further condition if (ackseq <= unackseq)is not met, and, as a result, we are going to reset label. From Jakub Łągwa (2016-06-20). * SYSLOG: Remove lowsyslog(), vlowsyslog(), and associated macros *llinfo(), *llwarn(), and llerr(). In the redesigned syslog() logic, these serve no purpose (2016-06-20). * Make system: Need to build the drivers/ directory even it file descriptors are not supported. There are things in the drivers/ directory that are still needed (like SYSLOG logic) (2016-06-20). * assert.h: Define static assert for C++ usage. From Paul Alexander Patience (2016-06-21). * arch/arm/src/stm32l4: Add ioctls to set/get bit timing in stm32l4. Add ioctl hooks to allow future management of can id filters. From Sebastien Lorquet (2016-06-21). * drivers/can.c: Add support for poll. From Paul Alexander Patience (2016-06-21). * drivers/syslog: Extend SYSLOG logic so that we can send SYSLOG output to a file. Not verified on initial commit (2016-06-21). * arch/arm/src/stm32l4: Add some CAN mode IOCTL calls. These will be useful for device autotest when the application boots. They are redundant with the CONFIG_CAN_LOOPBACK option, which can now just be interpreted as a default setting. From Sebastien Lorquet (2016-06-22). * drivers/syslog: syslog_dev_flush() needs to check if the inode is a mountpoint before calling the flush() method. Noted by David Sidrane (2016-06-22). * arch/arm/src/stm32f7: Adds SDMMC1 for stm32F7 74-75. From Lok Tep (2016-06-22). * drivers/syslog: SYSLOG character device channel will now expand LF to CR-LF. Controllable with a configuration option (2016-06-22). * arch/arm/src/stm32l4: Implementation of loopback IOCTLs. From Sebastien Lorquet (2016-06-22). * Documentation: Add SYSLOG documentation to the porting guide (2016-06-22). * configs/stm32f746g-disco: Removed knsh configuration it failed to refresh (via tools/refresh.sh). I assume that it is a hand-edited configuration and, hence, must be removed from the repository (2016-06-23). * arch/arm/arc/sam34: DAC bugfix: DACC_WPMR_WPKEY_MASK -> DACC_WPMR_WPKEY. Timer bugfix: Fix ops check in TCIOC_STOP. From Wolfgang Reissnegge (2016-06-23). * configs/nucleo-144: Added SDMMC support to Nucleo-144. From David Sidrane (2016-06-23). * arch/arm/src/stm32: Port STM32L4 CAN IOCTLs to STM32. From Sebastien Lorquet (2016-06-24). * drivers/ioexpander: Add support for a very simple GPIO driver. It supports only pre-conrigured input and output pins and only basic input and output operations (2016-06-24). * arch/arm/src/lpc43xx: Correct auto-negotiation mode in the LPC43xx Ethernet. From Alexander Vasiljev (2016-06-24) * arch/arm/src/samv7: TWIHS Driver improved and GPIO-Driver fixed for Open-Drain Pins - sam_gpioread: Now the actual line level from the pin is read back. This is extremely important for Open-Drain Pins, which can be used bidirectionally - Re-Implemented twi_reset-function and enhanced it so it can be called from inside the driver (see next point) - Glitch-Filter: Added a configuration option to enable the twi-built- in glitch filter - Added a "Single Master Mode": In EMC Testing the TWI-Bus got stuck because the TWI-Master detected a Multi-Master access (but there is no second master). With the option "Single Master" we detect these events and automatically trigger a twi_reset. We also do an automatic recovery if a slave got stuck (SDA stays low). With the above changes I²C-Bus reliability in harsh environments (eg. EMC) is greatly improved. The small change in the GPIO-Driver was necessary because otherwise you cannot read back the correct line status of Open-Drain Outputs and this is needed by the twi_reset function. From Michael Spahlinger (2016-06-24) * arch/arm/src/stm32f7: BUGFIX:PLLs IS2 and SAI P Calculation. From David Sidrane (2016-06-24). * arch/arm/src/stm32f7: USB support. From Lok Tep (2016-06-27). * configs/olimex-stm32-e407: Add support for Olimex STM32 E407 board. From Mateusz Szafoni (2016-06-27). * drivers/ioexpander: Shadow-Mode: The output- and configuration registers of the IO-Expander are held in the microcontrollers memory and only written to the IO-Expander. This reduces bus traffic and is more error-proof than the normal read-modify-write operation. Retry Mode: If enabled and an error occurs while writing to the IO-Expander the current transmission is automatically repeated once. From Michael Spahlinger (2016-06-27). * libc/hex2bin: Move the portable library portion of apps/system/hex2bin to nuttx/libc/hex2bin where it can be shared with the OS internals (2016-06-27). * configs/nucleo-144: Added USB OTG device to Nucleo-144. From David Sidrane (2016-06-27). * arch/arm/src/stm32l4: STM32 CAN fixes need to be backported to STM32L4 as well (2016-06-27). * ARM stack check: Fix double fault on IDLE task with stack size = 0. From David Sidrane (2016-06-27). * configs/nucleo-144: Added bbsram test to Nucleo-144. From David Sidrane (2016-06-27). * arch/arm/src/stm32f7: Added PWR, RTC, and BBSRAM support for stm32f7. From David Sidrane (2016-06-27). * Build system: Fixed build of SAMV71-XULT/nsh. With the changes from 26f7b8c the build process of the default configuration did not succeed anymore. From Michael Spahlinger (2016-06-28). * sched/semaphore: Need to set errno to EINVAL on errors in sem_post() and sem_wait(). From Paul Alexander Patience (2016-06-28). * Build system: This change fixes a build problem that only occurs when reconfiguring from Linux to Windows or vice-versa. It is a problem that was present but not usually experienced until two things happened: (1) The pre_config target was added to run before the menconfig operation and (2) the context target was added before the pre_config target in order to set up the correct symbolic links (in the apps/platform directory) needed by the pre_config target. But then now if you start with a Linux system and run 'make menuconfig' to switch to Linux, the context target will execute first and set up POSIX style symbolic links before doing the menuconfig. Then after the menuconfig, the make will fail on Windows if you are using a Windows native toolchain because that native toolchain cannot follow the Cygwin- style symbolic links. The fix here is to also execute the clean_context AFTER executing menuconfig. A lot more happens now: It used to be that doing 'make menuconfig' only did the menuconfig operation. Now it does context, pre_config, menuconfig, clean_context. Not nearly as snappy as it used to be (2016-06-28). * arch/arm/src/efm32, lcp43, stm32, stm32l4: disable interrupts with NVIC_IRQ_CLEAR. From Paul Alexander Patience (2016-06-28). * arch/arm/src/stm32f7: STMF7xxx RTC: (1) Remove proxy #defines, (2) Ensure the LSE(ON) etal are set and remembered in a) A cold start (RTC_MAGIC invalid) of the RTC, and b) A warm start (RTC_MAGIC valid) of the RTC but a clock change. The change was needed because in bench testing a merge of the latest's STM32 53ec3ca (and friends) it became apparent that the sequence of operation is wrong in the reset of the Backup Domain in the RCC code. PWR is required before the Backup Domain can be futzed with. !!!This Code should be tested on STM32 and if needed rippled to the STM32 families. From David Sidrane (2016-06-28). * arch/arm/src/stm32f7: Added STMF7xxx RTC. From David Sidrane (2016-06-28). * arch/arm/src/stm32: STM32 BBSRAM fixed (and formatted) flags. From David Sidrane (2016-06-28). * arch/arm/src/stm32f7: STM32F7 BBSRAM fixed (and formatted) flags. From David Sidrane (2016-06-28). * arch/arm/src/stm32f7: Added STM32F7 DBGMCU. From David Sidrane (2016-06-28). * arch/arm/src/samv7: SAMV7: CAN Message Filtering fixed: (1) stdfilters didn't work because the filter was never enabled (wrong number of bits to shift), and (2) Filters were never used because the configuration register cannot be written without using the initialization mode. Both bugs are fixed by this change. Filtering has been tested with both standard and extended identifiers and is now working properly. From Michael Spahlinger (2016-06-29). * configs/Kconfig and dummy/: Add logic to support custom board directories that include a Kconfig file. During the context phase of the build, any Kconfig file in the custom board directory is copied into configs/dummy, replacing the existing Kconfig file with the target Kconfig file (2016-06-29). * arch/arm/src/stm32l4: Port support for both RX FIFOs from STM32 CAN. From Paul Alexander Patience (2016-06-29). * Remove all inclusion of header files from the apps/include directory. This caused a lot of reshuffling of logic: binfmt pcode support, usbmonitor is now a kernel thread, TZ/Olson database moved to libc/zoneinfo (2016-06-29). * drivers/mtd: Several MTD FLASH drivers nullify the freed 'priv' structure and failed to return NULL as stated in the comments. Result, will operate on a NULL pointer later. Noted by David Sidrane (2016-06-30). * arch/arm/src/kinetis: Add basic support for the K64 family. I leveraged the changes from https://github.com/jmacintyre/nuttx-k64f and merged into the existing kinetis code with a lot of changes and additions (like pin multiplexing definitions). (2016-07-01). * configs/freedom-k64f: Add support for the NXP Freedom-K64F board. This is primarily the work of Jordan Macintyre. I leveraged this code from https://github.com/jmacintyre/nuttx-k64f but with significant corrections (LEDs, buttons, README, etc) and extensions and updates to match more recent BSPs (2016-07-01). * libc/signal: Add raise() (2016-07-04). * drivers/syslog: Add a SYSLOG character device that can be used to re- direct output to the SYSLOG (2016-07-05). * net/netdev: Break out internal interface psock_ioctl() (2016-07-06). * configs/stm32f4disovery: Add can driver for stm32f4discovery. From Matthias Renner (2016-07-06). * configs/freedom-k64f: Increase MCU clock to 120MHz (2016-07-06). * arch/arm/src/stm32: Add support for Tickless mode (two timer implementation). From Max Neklyudov (2016-07-06). * drivers/usbdev: cdcacm_unbind leaks write request objects. This arises due to freeing the bulk IN endpoint before the loop that frees the requests via cdcasm_freereq. That function checks the parameters and skips the freeing if either is NULL. Freeing the bulk IN enpoint will cause the first param to be NULL, thereby bypassing the free operation. To fix, I moved the release of the bulk IN endpoint until after to loop (much as was the case for the OUT and read requests, which did not exhibit the problem). From ziggurat29 (2016-07-07). * arch/arm/src/stm32l4: Update usb dev/host controller drivers to reflect new(ish) logging standards; augment device enpoint and fifo allocation #defines to do more sanity checking, and be automatically adaptive to size changes. Update README.txt to reflect current status of the implementation. From ziggurat29 (2016-07-07). * arch/arm/src/stm32f7: Fixed STM32F7 DMA stm32_dmacapable. DMA working on SDMMC. From David Sidrane (2016-07-07). * configs/stm32f4discovery: add configuration files for canard. From Matthias Renner (2016-07-08). * drivers/pipe: Add missing configuration for pipe ring buffer size. From Frank Benkert (2016-07-08). * STM32L4: Fix incorrect clock setup for LPTIM1. From ziggurat29 (2016-07-08). * nucleo-l476rg and stm32lf76vg-disco: Define timer clock frequencies on STM32L4-based boards. From ziggurat29 (2016-07-08). * STM32L4: Add support for tickless OS, and incidentally timers, pwm, oneshot, free-running.... From ziggurat29 (2016-07-08). * SAM3/4 I2C: Fix reversed logic in twi_startmessage(). From Wolfgang Reissnegger (2016-07-09). * VFS ioctl(). Per comments from David Sidrane, file_ioctl() should not return succeed if the ioctl method is not supported. It probably should return ENOTTY in that case (2016-07-09). * libm: This change should significantly improve the performance of single precision floating point math library functions. The vast majority of changes have to do with preventing the compiler from needlessly promoting floats to doubles, performing the calculation with doubles, only to demote the result to float. These changes only affect the math lib functions that return float. From David Alessio (2016-07-11). * STM32F4 Discovery: Add FPU support for ostest for the STM32F4Discovery platform. From David Alessio (2016-07-11). * Build system: Remove the includes/apps link to apps/include. It is no longer used. From Sebastien Lorquet (2016-07-11). * printf(): If there are no streams, let printf() fall back to use syslog() for output (2016-07-11). * Qemu-i486: Fix qemu-i486/ostest/Make.defs test for M32. From Heath Petersen (2016-07-12). * UART 16550: Handle when CONFIG_SERIAL_UART_ARCH_IOCTL is not enabled. From Heath Petersen (2016-07-12). * Kinetis Ethernet: Add support for the KSZ8081 PHY (2016-07-12). * SST26 Driver: Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver. BUT re- reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done. I have no idea how the driver currently works except by chance. The writes should never happen at all, the flash is half-enabled! From Sebastien Lorquet (2016-07-12). * Freedom K64F: Add a networking NSH configuration. (2016-07-12). * N25Qxx Driver: Alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well). Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults. Trivial spelling changes in comments, etc. From ziggurat29 (2016-07-12). * STM32L476 Discovery: Update stm32l476 disco to include init code for smartfs and nxffs for cases where those fs are included in build. From ziggurat29 (2016-07-12). * Kinetis Ethernet and Freedom-K64F: Freedcom-K64F PHY address was wrong. Modified Ethernet driver to try all PHY addresses and then only fail if the driver cannot find a usable PHY address. MDIO pin must have an internal pull-up on the Freedom-K64F (2016-07-12). * Kinetis Ethernet: Add support for CONFIG_NET_NOINTS (2016-07-12). * SmartFS: Fix a 32-byte memory leak. From Ken Pettit (2016-07-12). * Freedom-K64F: SDHC is now enabled in the nsh configuration (but does not work)Add hooks for automounter; Change NSH configuration to use Windows (2016-07-13). * SAMV7 USBHS Device: This change solves a problem which causes data loss while sending data via USB. This problem is caused by an incorrect handling of the endpoint state in the USB driver sam_usbdevhs. This leads under some circumstances to situations in which an DMA transfer is setup while a previous DMA transfer is currently active. Amongst other things I introduced the new endpoint state USBHS_EPSTATE_SENDING_DMA for the fix. To reproduce the problem, I used a program which send as many data as possible via a CDC/ACM device and verified the received data on the PC. From Stefan Kolb (2016-07-13). * STM32: Fix bug in oneshot timer. From Max Neklyudov (2016-07-13). * STM32L4: Port foward bugfix from stm32 of oneshot timer. From ziggurat29 (2016-07-13). * STM32 and EFM32: I'm using syslog through ITM. In this case syslog_channel function is call before RAM initialisation in stm32_clockconfig. But syslog channel uses a global variable that is reset to default by the RAM initialization. From Pierre-noel Bouteville (2016-07-14). * LPC43xx SPIFI: If CONFIG_SPIFI_SECTOR512 undefined, lpc43_bwrite doesn't do actual write (probably copy/paste errors). Still not sure about current state of lpc43_spifi implementation, but for me NXFFS works with this patch. From Vytautas Lukenskas (2016-07-14). * SMART MTD layer: Fixes freesector logic error when sectorsPerBlk=256, adds DEBUGASSERT for invalid geometry and additional memory debug logic. Also fixes the dangling pointer on error bug. From Ken Pettit (2016-07-14). * arch/arm/src/lpc43xx: Extend LPC43xx EMC code to support SDRAM on a dynamic memory interface. From Vytautas Lukenskas (2016-07-19). * arch/sim/src: Add the simulated QSPI (N25Q) flash to the simulation and modify sim up_spiflash.c to enable it to run with different MTD drivers based on config options (currently m25p, sst26 and w25). From Ken Pettit (2016-07-19). * drivers/pipe: Add support to allocating different sizes for pipe and fifo buffers. Adds mkfifo2() and pipe2() which are just like mkfifo() and pipe(), but allow control of the size of the underlying, in-memory circular buffer . Move pipe() and mkpipe() to nuttx/libc, they are no longer core OS interfaces. Capability currenty used only by PTY logic to support, configurable, smaller buffers for PTYs (2016-07-19). * include/nuttx/drivers: Move driver-related files from include/nuttx to include/nuttx/drivers. Move driver related prototypes out of include/nuttx/fs/fs.h and into new include/drivers/drivers.h (2016-07-20). * include /nuttx/lib: Move library-related files from include/nuttx to include/nuttx/lib (2016-07-21). * drivers/serial/serial.c: Fix a race condition noted by Stefan Kolb. Between the test if the TX buffer is full and entering a critical section, bytes may be removed from the TX buffer making the wait unnecessary. The unnecessary wait is an inefficiency, but not really a problem. But with USB CDC/ACM it can be a problem because the entire TX buffer may be emptied when we lose the race. If that happens that uart_putxmitchar() can hang waiting for data to be removed from an empty TX buffer (2016-07-22). * arch/arm/src/stm32 and stm32l4: STM32 F4/L4 RTC ALARM: were enabling interrupts too early in the power-up sequence, BEFORE the interrupt system was being initialized (2016-07-23). * drivers/ioexpander: GPIO driver: Add support for receiving signals from interrupt pins (2016-07-23). * drivers/usbdev: USBMSC: Add locks when removing request from queue. From Wolfgang Reissnegger (2016-07-23). * drivers/usbdev: USBMSC: Fix reversed logic on waiting for SCSI thread start. The scsi thread was waiting for the wrong condition. However, this was masked by the fact that the code creating the scsi thread was also holding usbmsc_scsi_lock(priv) while initializing data, hence this lock synchronized the scsi thread start with init completion. From Wolfgang Reissnegger (2016-07-23). * arch/arm/src/sam34: SAM3/4 UDP: Fix handling of endpoint RX FIFO banks. This fixes a race condition where the HW fills a FIFO bank while the SW is busy, resulting in out of sequence USB packets (2016-07-23). * Freedom-K64F: Add PWM support. From Jordan MacIntyre (2016-07-25). 7.18 2016-10-08 Gregory Nutt * drivers/serial/pty.c, serial.c, usbdev/cdcacm.c, include/nuttx/fs/ioctl.h: Fix FIONWRITE and add FIONSPACE. All implementations of FIONWRITE were wrong. FIONWRITE should return the number of bytes waiting in the outgoing send queue, not the free space. Rather, FIONSPACE should return the free space in the send queue (2016-07-25). * lib_dumpbuffer: Now prints a large on-stack buffer first to avoid problems when the syslog output is prefixed with time. From Pierre- noel Bouteville (2016-07-27). * sched/clock and sched/sched: Add standard adjtime() interface and basic timekeeping support. Normally used with an NTP client to keep system time in synchronizationi. From Max Neklyudov (Merged on 20160-07-28). * arch/arm/src/stm32: Add timekeeping support for the STM32 tickless mode. From Max Neklyudov (Merged on 20160-07-28). * Top-Level Makefiles. Fix a chicken-and-egg problem. In the menuconfig target, the context dependency was executed before kconfig-mconf. That was necessary because the link at apps/platform/board needed to be set up before creating the apps/Kconfig file. Otherwise, the platform Kconfig files would not be included. But this introduces the chicken-and-egg problem in some configurations. In particular: (1) An NX graphics configuration is used that requires auto-generation of source files using cpp, (2) the configuration is set for Linux, but (3) we are running under Cygwin with (4) a Windows native toolchain. In this case, POSIX-style symbolic links are set up but the Windows native toolchain cannot follow them. The reason we are running 'make menuconfig' is to change from Linux to Cygwin, but the target fails. During the context phase, NX runs CPP to generate source files but that fails because the Windows native toolchain cannot follow the links. Checkmate. This was fixed by changing all of the make menuconfig (and related) targets. They no longer depend on context being run. Instead, they depend only on the dirlinks target. The dirlinks target only sets up the directory links but does not try to run all of the context setup; the compiler is never invoked; no code is autogeneraed; and things work (2016-07-28). * tools/refresh.sh: Recent complexities added to apps/ means that configuration needs correct Make.defs file in place in order to configure properly (2016-07-28). * tools/kconfig2html.c: Update to handle absolute paths when sourcing Kconfig files (2016-07-29). * libc/math: This fixes the following libc/math issues: (1) asin[f l]() use Newton’s method to converge on a solution. But Newton’s method converges very slowly (> 500,000 iterations) for values of x close to 1.0; and, in the case of asinl(), sometimes fails to converge (loops forever). The attached patch uses an trig identity for values of x > sqrt(2). The resultant functions converge in no more than 5 iterations, 6 for asinl(). (2) The NuttX erf[f l]() functions are based on Chebyshev fitting to a good guess. The problem there’s a bug in the implementation that causes the functions to blow up with x near -3.0. This patch fixes that problem. It should be noted that this method returns the error function erf(x) with fractional error less than 1.2E-07 and that’s fine for the float version erff(), but the same method is used for double and long double version which will yield only slightly better precision. This patch doesn't address the issue of lower precision for erf() and erfl(). (3) a faster version of copysignf() for floats is included. From David S. Alessio (2016-07-30). * I/O Expander: Remove hard-coded PCA9555 fields from ioexpander.h definitons. Add support for an attach() method that may be used when any subset of pin interrupts occur (2016-07-31). * PCA9555 Driver: Replace the signalling logic with a simple callback using the new definitons of ioexpander.h. This repartitioning of functionality is necessary because (1) the I/O expander driver is the lower-lower part of any driver that uses GPIOs (include the GPIO driver itself) and should not be interacting directly with the much higher level application layer. And (2) in order to be compatible with the GPIO driver (and any arbitrary upper half driver), the PCA9555 should not directly signal, but should call back into the upper half. The upper half driver that interacts directly with the application is the appropriate place to be generating signal (2016-07-31). * drivers/ioexpander/skeleton.c: Add a skeleton I/O Expander driver (based on the PCA9555 driver) (2016-07-31). * I/O Expander Interface: Encode and extend I/O expander options to include interrupt configuration (2016-07-31). * drivers/ioexpander: Add an (untested) TCA64XX I/O Expander driver leveraged from Project Ara (2016-07-31). * I/O Expander Interface: Add argument to interrupt callback. Add a method to detach the interrupt (2016-08-01). * drivers/ioexpander: Add a GPIO lower-half driver that can be used to register a GPIO character driver for accessing pins on an I/O expander (2016-08-01). * drivers/ioexpander: Add PCF8574 I/O Expander driver. Some cleanup also of other expander drivers (2016-08-01). * drivers/ioexpander: GPIO driver: Add IOCTLs to get the pin type and to unregister a signal handler (2016-08-01). * configs/sim: Add simulator-based test support for apps/examples/gpio 2016-08-01). * drivers/sensors: Add KXTJ9 Accelerometer driver from the Motorola Moto Z MDK (2016-08-02). * arch/arm/sim: Add a simulated I/O Expander driver (2016-08-03). * configs/sim: Add logic to set the simulated I/O expander for testing with apps/examples/gpio (2016-08-03). * fs/fat: FAT performance improvement. In large files, seeking to a position from the beginning of the file can be very time consuming. ftell does lssek(fd, 0, SET_CURR). In that case, that is wasted time since we are going to seek to the same position. This fix short- circutes fat_seek() in all cases where we attempt to seek to current position. Suggested by Nate Weibley (2016-08-03). * tools/sethost.sh: Add sethost.sh. This is a script that you can use to quickly change the host platform from Linux to Windows/Cygwin. Might save you a lot of headaches (2016-08-03). * arch/arm/src/tiva: Add tiva PWM lower-half driver implementation. From Young (2016-08-05). * drivers/spi/spi_transfer.c: Add a helper function that encapsulates and manages a sequence of SPI transfers (2016-08-05). * drivers/spi: Add an SPI character driver that will permit access to the SPI bus for testing purposes. This driver is a simple wrapper around spi_transfer() (2016-08-05). * drivers/wireless: Add MFRC522 RFID ISO14443 and Mifare transceiver driver. From Alan Carvalho de Assis (2016-08-06). * configs/stm32f103-minimum: Add board support to MFRC522 driver. From Alan Carvalho de Assis (2016-08-06). * arch/renesas: Rename arch/sh to arch/renesas (2016-08-06). * arch/arm/src/efm32, stm32, stm32l4: STM32 and EFM32 SPI drivers adopted an incompatible conventions somewhere along the line. The set the number of bits to negative when calling SPI_SETBITS which had the magical side-effect of setting LSB first order of bit transmission. This is not only a hokey way to pass control information but is supported by no other SPI drivers. This change three things: (1) It adds HWFEAT_LSBFIRST as a new H/W feature. (2) It changes the implementations of SPI_SETBITS in the STM32 and EFM32 derivers so that negated bit numbers are simply errors and it adds the SPI_HWFEATURES method that can set the LSB bit order, and (3) It changes all calls with negative number of bits from all drivers: The number of bits is now always positive and SPI_HWFEATURES is called with HWFEAT_LSBFIRST to set the bit order (2016-08-08). * arch/arm/src/stm32: Add missing SPI2 and SPI3 support for STM32F3F3. Add STM32F37XX DMA channel configuration. For STM32F37XX, SYSCFG_EXTICR_PORTE defined twice. From Alan Carvalho de Assis (2016-08-08). * arch/arm/src/stm32: Make stm32_pwr_enablebkp thread safe. From Max Neklyudov (2016-08-09). * arch/arm/src/stm32: SAM3/4 GPIO: Enable peripheral clock for GPIO port when GPIO is configured as input. The value of a GPIO input is only sampled when the peripheral clock for the port controller the GPIO resides in is enabled. Therefore we need to enable the clock even when polling a GPIO. From Wolfgang Reissnegger (2016-08-09). * arch/arm/src/tiva: Fix two bugs of tiva pwm lower-half driver implementation. From Young (2016-08-10). * sched/group: Explicitly initialize the group tg_exitsem with sem_init(). The existing logic worked because the correct initialization value is all zero, but it is better to initialize the semaphore explicitly (2016-08-10). * arch/arm/stm32: Fix bad pllmul values for STM32F1XX connectivity line. STM32F1XX connectivity line supports only x4, x5, x6, x7, x8, x9 and x6.5 values. From Michał Łyszczek (2016-08-11). * include/nuttx/timers: Add oneshot timer lower half interface (2016-08-11). * arch/arm/src/stm32: Add a experimental oneshot, lower-half driver for STM32 (2016-08-11). * arch/arm/src/samv7: Add option to support oneshot timer without free- running timer.

That and data packing work differently on the STM32F3 than for other STM32 parts (2016-08-12). * arch/arm/stm32 and stm32l4: Enabling SPI DMA loses other bits in CR2 (2016-08-13). * arch/arm/src/stm32: STM32F3 SPI: Cannot write always 16-bit value to DR register because of how the F3 implements data packing (2016-08-13). * Kinetis: Add support for I2C and RTC. From v01d (phreakuencies) (2016-08-13). * teensy 3.x i2c. From v01d (phreakuencies) (2016-08-13). * SH1106 0.96 OLED module support (SSD1306 compatible) + I2C fixes.

From Alan Carvalho de Assis (2016-08-16). * STM32F411 and STM32F446 map i2c2_sda_4 to different alternate function numbers. From Konstantin Berezenko (2016-08-17). * STM32 DMA Fix: Change stm32 adc dma callback to send channel number instead of index. From Konstantin Berezenko (2016-08-17). * SAMA5: Add missing oneshot max_delay method (2016-08-18). * configs/stm32bufferfly2: Add support for the Kamami stm32butterfly2 development board with optional ETH phy. From Michał Łyszczek (2016-08-19). * libc/misc: Separate XorShift128 PRNG from /dev/urandom and make it generally available (2016-08-20). * sched/sched_cpuload_oneshot: Use the oneshot timer with optional entropy to measure cPU load if so configured (2016-08-20). * drivers/usbhost/usbhost_composite.c: An an EXPERIMENTAL prototype of how USB host support for composite devices might be implemented. This feature is EXPERIMENTAL because (1) it is untested and (2) has some know design issues that must be addressed before it can be of use (2016-08-28). * CXXFLAGS: Add -fcheck-new whenever -fno-exceptions is used. From Beat Küng (2016-08-23). * tools/mkfsdata.pl was still generating the old-style apps/include inclusion paths (2016-08-23). * drivers/sensors: Add drvier for the LIS3MDL 3 axis magnetometer.

From Sebastien Lorquet (2016-08-25). * STM32 OTGFS device: Fix for lost first word from FIFO 1) Do not overwrite Reserved Bits in GINTSTS (per ref manual)* 2) Acknowledge all pending int on entry to ISR that are Only rc_w1* 3) Do not disable RXFVL* 4) Loop until RXFVL is cleared* 5) Only clear the NAK on the endpoint on the OTGFS_GRXSTSD_PKTSTS_SETUPDONE to not loose the first WORD of FIFO all the data (Bug Fix) Changed marked *are just driver clean up and ensure ints are not lost. The bug fix is #5 Test case open putty and observer the Set/Get LineCoding. Without this fix #5 the Get will not match the Set, and in fact the data might be skewed by 4 bytes, that are lost from the FIFO if the OTGFS_DOEPCTL0_CNAK bit is set in the OTGFS_GRXSTSD_PKTSTS_SETUPRECVD as opposed to the OTGFS_GRXSTSD_PKTSTS_SETUPDONE Set Line Coding DATA1: 4B | 00 c2 01 00 00 00 08 | c8 1B Get Line Coding DATA1: 4B | .. .. .. .. 00 00 08 c8 .. 00 00 07 | 7a 72 From David Sidrane (2016-08-25). * Add system() to stdlib.h.

For STM32L4 parts, the higher number USART ports supported varies. Add the HAVE_USARTx definitions to the configuration to allow enabling the higher numbered USART ports. From Jim Wylder (2016-09-15). * configs/stm32l476-mdk: Support basic booting and nsh on Motorola MDK. The Motorola MDK is based off of an earlier version of NuttX.

From Vladimir Komendantskiy (2016-09-20). * SAM3/4: Fix GPIO pull-up/down code. Enabling the pull-down resistor while the pull-up resistor is still enabled is not possible. In this case, the write of PIO_PPDER for the relevant I/O line is discarded. Likewise, enabling the pull-up resistor while the pull-down resistor is still enabled is not possible. In this case, the write of PIO_PUER for the relevant I/O line is discarded. From Wolfgang Reißnegger (2016-09-20). * SAM GPIO: Apply Wolfgang's change for SAM3/4 to SAMA5 and SAMV7 (2016-09-20). * Tiva QEI: Add QEI lower-half driver impl. for Tiva series chip.

From Mateusz Szafoni (2016-09-22). * sched/: vector table should have dimension NR_IRQS, not NR_IRQS+1. From Sagitta Li (2016-09-22). * fs/mount: Corrects a bad assertion noted by Pierre-noel Bouteville. Also fixes a reference counting problem in an error condition: When the mountpoint inode is found but is not an appropriate mountpoint, the reference count on the inode was not being decremented (2016-09-22). * libnx/nxglib: Fix handling of near-horizontal lines of width 1 in nxgl_splitline(). Missing handling for degenerate condition caused width 1 lines such as (0, 0) - (100, 10) to have gaps in the drawing. From Petteri Aimonen (2016-09-22). * drivers/net/slip.c: Fix calculations using MSEC_PER_TICK. If USEC_PER_TICK is less than 1000, then MSEC_PER_TICK will be zero. It will be inaccurate in any case (2016-09-25). * Tiva QEI: Add a new ioctl command (set MAXPOS) for tiva QEI. From Young (2016-09-26). * LPC43xx Serial: There are some small problems in LPC43xx RS485 mode configuration. In particular: (1) UART0,2,3 do not have DTR pins (different from UART1), so, Kconfig needs to be adjusted. (2) lpc43_uart.c in RS485 mode only configures DIR pin, but doesn't enable pin output for UART0,2,3. (3) should be option to reverse DIR control pin output polarity. (4) lpc43xx/chip/lpc43_uart.h doesn't have USART3 definitions. NOTE: I didn't modified and didn't tested USART1, as it has different hardware. From Vytautas Lukenskas. From Vytautas Lukenskas (2016-09-30). * STM32 Ethernet: Correct typo in conditional logic. From Neil Hancock (2016-10-01). * sched/pthread and task: When a pthread is started, there is a small bit of logic that will run on the thread of execution of the new pthread. In the case where the new pthread has a lower priority than the parent thread, then this could cause both the parent thread and the new pthread to be blocked at the priority of the lower priority pthread (assuming that CONFIG_PRIORITY_INHERITANCE is not selected). This change temporarily boosts the priority of the new pthread to at least the priority of the new pthread to at least the priority of the parent thread. When that bit of logic has executed on the thread of execution of the new pthread, it will then drop to the correct priority (if necessary) before calling into the new pthread's entry point (2016-10-01). * configs/stm32f103-minimum: Add stm32_bringup support and userled example to STM32F103 Minimum board.

I will be making the FPGA code for this available soon (within a week I would say). The board support on this is pretty thin, but it seems like maybe a good idea to get the base RISC-V stuff in since there are people interested in it. From Ken Pettit (2016-10-16). * C library: Add a dummy setlocale() function to avoid drawing the function from newlib (2016-10-17). * libc/wchar: Add wcslen, wmemchr, wmemcmp, wmemcpy and wmemset to NuttX.

From Maciej Wójcik (2016-10-19). * libc/locale: Allows c++ code to compile with or without CONFIG_LIBC_LOCALE and will generate a link error if CONFIG_LIBC_LOCALE is not defined and setlocale is referenced. With CONFIG_LIBC_LOCALE defined setlocale will act as if MB string is not supported and return "C" for POSIX. C and "".

From Frank Benkert (2016-10-21). * configs/*/defconfig: The buttons example was changed to archbuttons. As a result all of the button configurations are broken and need some renaming in the defconfig files. Noted by Frank Berkert (2016-10-21). * configs/stm32f103-minimum: Add support to PWM on STM32F103-Minimum board. From Alan Carvalho de Assis (2016-10-21). * include/ctype.h and cxx/cctype: Implement ctype.h functions as inline if possible. cctype can then properly select namespace (2016-10-22). * libc/unisted: Add strtold() (2016-10-22). * sscanf: Use strtof() instead of strtod() if a short floating point value was requested.

From Alan Carvalho de Assis (2016-10-25). * arch/arm/src/stm32: Initial implemention of the STM32 F37xx SDADC module. There are also changes to ADC, DAC modules. SDADC has only been tested in DMA mode and does not support external TIMER triggers. This is a work in progress. From Marc Rechté (2016-10-25). * Add logic to attach peripheral interrupt sources to CPU interrupts (2016-10-25). * CHxN channels are always outputs. From Sebastien Lorquet (2016-10-26). * sched/semaphore: Within the OS, when a thread obtains a semaphore count it must call sem_addholder() if CONFIG_PRIORITY_INHERITANCE is enabled. If a count is available, then sem_wait() calls sem_addholder(), otherwise it waited for the semaphore and called sem_addholder() when it eventually received the count. This caused a problem when the thread calling sem_wait() was very low priority. When it received the count, there may be higher priority threads "hogging" the CPU that prevent the lower priority task from running and, as a result, the sem_addholder() may be elayed indefinitely. The fix was to have sem_post() call sem_addholder() just before restarting the thread waiting for the semaphore count. This problem was noted by Benix Vincent who also suggested the solution (2016-10-26). * configs/stm32f103-minimum: Add RGB LED support on STM32F103 Minimum board. From Alan Carvalho de Assis (2016-10-26). * arch/arm/src/stm32f7: stm32_i2c.c Dejavu. Fixes a bug previously found in the F4.

Patience (2016-11-02). * drivers/ and drivers/spi: Fix Kconfig warning. This commit moves the ARCH_HAVE_SPI options outside the check for SPI. Those options don't depend on SPI, and Kconfig files in arch/ enable them even if SPI isn't enabled. Source the driver's Kconfig in drivers/Kconfig only if support for the driver is enabled prevents us from defining these ARCH_HAVE options in the driver's Kconfig. We should probably remove the other checks in drivers/Kconfig and check if the drivers are enabled only in their Kconfig. From Paul A. Patience (2016-11-02). * Move protoypes for the non-standard include/semaphore.h file to the non-standard include/nuttx/semaphore.h with the other non-standard semaphore interfaces (2016-11-02). * include/semaphores.h: Provide macros for sem_setprotocol() and sem_getprotocol() if priority inheritance is not enabled.

This commit fixes compilation errors on MPU support for ARMv7-R. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Fix invalid drbar handling. In ARMv7-R, [31:5] bits of DRBAR is physical base address and other bits are reserved and SBZ. Thus, there is no point in passing other than the base address. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Remove the redundant update on SCTLR. mpu_control() is invoking cp15_wrsctlr() around SCTLR update redundantly. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Add new Kconfig entries for d/i-cache. Unlike in ARMv7-A/M, Kconfig entries for data and instruction caches are currently missing in ARMv7-R. This commit adds those missing Kconfig entries. Actual implmenetation for those functions will be added in the subsequent patches. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Add cache handling functions. This commit adds functions for enabling and disabling d/i-caches which were missing for ARMv7-R. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Fix typo in mpu support. s/ARMV7M/ARMV7R/g. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Fix CPSR corruption after exception handling. A sporadic hang with consequent crash was observed when booting. It seemed to be caused by the corrupted or wrong CPSR restored on return from exception. NuttX restores the context using code like this: msr spsr, r1 GCC translates this to: msr spsr_fc, r1 As a result, not all SPSR fields are updated on exception return. This should be: msr spsr_fsxc, r1 On some evaluation boards, spsr_svc may have totally invalid value at power-on-reset. As it is not initialized at boot, the code above may result in the corruption of cpsr and thus unexpected behavior. From Heesub Shin (2016-11-06). * arch/arm/src/armv7-r: Fix to restore the Thumb flag in CPSR. Thumb flag in CPSR is not restored back when the context switch occurs while executing thumb instruction. From Heesub Shin (2016-11-06). * sched/wqueue: When queuing new LP work, don't signal any threads if they are all busy. From Heesub Shin (2016-11-06). * sched/wqueue: Signal sent from work_signal() may interrupt the low priority worker thread that is already running. For example, the worker thread that is waiting for a semaphore could be woken up by the signal and break any synchronization assumption as a result. It also does not make any sense to send signal if it is already running and busy. This commit fixes it. From Heesub Shin (2016-11-06). * arch/arm/src/stm32f7: STM32F7 SD/MMC driver depends on CONFIG_SDIO_DMA which is only defined in stm32/Kconfig. Changed to CONFIG_STM32F7_SDMMC_DMA and defined in stm32f7/Kconfig (2016-11-07). * arch/arm/src/stm32: Add PWM driver support for STMF37xx. The changes have been tested successfuly for TIM4 and TIM17 (different IPs). From Marc Rechté (2016-11-07). * sched/semaphore: sem_trywait() no longer modifies the errno value UNLESS an error occurs. This allows these functions to be used internally without clobbering the errno value. From Freddie Chopin (2016-11-09). * arch/arm/src/stm32l4: Change the way to configure quadrature encoder prescalers. From Sebastien Lorquet (2016-11-09). * libc/unisted: Patch brings strtol() and related functions more conformant with POSIX. Corner cases like strtol(-2147483648, NULL, 10) now pass clang -fsanitize=integer without warnings. From Juha Niskanen (2016-11-10). * drivers/sensors and configs/stm32f103-minimum: Add Vishay VEML6070 driver and support for STM32F103-Minimum board. From From Alan Carvalho de Assis(2016-11-13). * Misoc LM32: Corrects a bug that never occured in qemu on simulation or real fpga. The error was that the r1 register was being modified out of context switching and not restoring it. From Ramtin Amin (2016-11-14) * arch/arm/src/samv71: A problem occurred with the SAMV7 USBDEVHS driver if the USB cable is unplugged while a large amount of data is send over an IN endpoint using DMA. If the USB cable is plugged in again after a few seconds it is not possible to send data over this IN endpoint again, all other endpoints work as expected. The problem occurs because if the USB cable is unplugged while an DMA transfer is in flight the transfer is canceled but the register SAM_USBHS_DEVDMACTRL is left in an undefined state. The problem was fixed the problem by resetting the register SAM_USBHS_DEVDMACTRL to a known state. Additionally all pending interrupts are cleared. From Stefan Kolb (2016-11-14). * configs/esp32-core: ESP32 Core v2: Add configuration to supporting linking NuttX for execution out of IRAM (2016-11-14). * libc/unistd: sleep() was returning remaining nanoseconds (kind of), instead the remaining seconds. From Eunbong Song (2016-11-15). * sched/irq: Fixes for the SMP case: (1) Change order for SMP case in enter_critical_section: (1) Disable local interrupts BEFORE taking spinlock and (2) If SMP is enabled, if any interrupt handler calls enter_critical_section(), it should take the spinlock. (2016-11-15). * arch/xtensa: Add EXPERIMENTAL hooks to support lazy Xtensa co- processor state restore in the future (2016-11-16). * Add some experimental changes to enter/leave_critical_section to deal with the case where interrupts are disabled only on the local CPU (2016-11-16). * sched/irq: Add logic to handled nested calls to enter_critical_section() from interrupts handlers (with SMP) (2016-11-16). * drivers/timer: Remove the timer driver TIOC_SETHANDLER IOCTL call. This calls directly from the timer driver into application code. That is non-standard, non-portable, and cannot be supported (2016-11-17). *drivers/timer: Add timer driver hooks to support signal notification of timer expiration. Commented out because invasive interface changes would also be required to complete the implementation (2016-11-17). * arch/arm/src/armv7-m: Fix double allocation of MPU region in mmu.h (2016-11-17). * timer driver: Use signal to notify of timer expiration. Add generic argument so that there can be additional usage. From Sebastien Lorquet (2016-11-17). * All timer lower half drivers. Port Sebastien's changes to all all other implementations of the timer lower half. Many changes and untested. Expect some problems. (2016-11-17). * sched/irq: irq_csection() has a bad assumption in the SMP case. It assumed that the state of certain variables. That was true on entry into the interrupt handler, but might change to the execution of logic within the interrupt handler (2016-11-18). * config/ nucleo-l476rg: Add support for timers to nucleo l476. From Sebastien Lorquet (2016-11-18). * drivers/net: Add option to use low-priority work queue to all drivers in drivers/net. Not yet added to all architecture-specific network drivers (2016-11-18). * sched/wdog: Most interrupt handling logic interacts with tasks via standard mechanism such as sem_post, sigqueue, mq_send, etc. These all call enter_critical_section and are assumed to be safe in the SMP case. But certain logic interacts with tasks in different ways. The only one that comes to mind are wdogs. There is a tasking interface that to manipulate wdogs, and a different interface in the timer interrupt handling logic to manage wdog expirations. In the normal case, this is fine. Since the tasking level code calls enter_critical_section, interrupts are disabled an no conflicts can occur. But that may not be the case in the SMP case. Most architectures do not permit disabling interrupts on other CPUs so enter_critical_section must work differently: Locks are required to protect code. So this change adds locking (via enter_critical section) to wdog expiration logic for the case if the SMP configuration (2016-11-18). * SAM3/4: Add delay between setting and clearing the endpoint RESET bit in sam_ep_resume(). We need to add a delay between setting and clearing the endpoint reset bit in SAM_UDP_RSTEP. Without the delay the USB controller will (may?) not reset the endpoint. If the endpoint is not being reset, the Data Toggle (DTGLE) bit will not to be cleared which will cause the next transaction to fail if DTGLE is 1. If that happens the host will time-out and reset the bus. Adding this delay may also fix the USBMSC_STALL_RACEWAR in usbmsc_scsi.c, however this has not been verified yet. From Wolfgang Reißnegger (2016-11-18). * SAM3/4: Remove unused 'halted' flag in UDP driver. From Wolfgang Reißnegger (2016-11-18). * SAM3/4: Remove 'stalled' flag in UDP driver. The flag is not necessary. The state of the endpoint can be determined using 'epstate' instead. From Wolfgang Reißnegger (2016-11-18). * USBMSC: Fix length of mode6 sense reply packet. From Wolfgang Reißnegger (2016-11-18). * configs/dk-tm4c129x: Typo fix. From Wolfgang Reißnegger (2016-11-18). * Typo fix in sam_udp.c. From Wolfgang Reißnegger (2016-11-18). * STM32: STM32F303xB and STM32F303xC chips have 4 ADCs. From Paul A. Patience (2016-11-19). * vfork(): Fix a race condition in the SMP case. Existing logic depended on the fact that the child would not run until waitpid was called because the child had the same priority as the parent. BUT in the SMP case that is not true... the child may run immediately on a different CPU (2016-11-19). * arch/: Add option to use low-priority work queue to all Ethernet drivers in arch that support CONFIG_NET_NOINTS (2016-11-19). * sched/clock: Correct calculation for the case of Tickless mode with a 32-bit timer. In that case, the calculation was returning millisecond accuracy. That is not good when the timer accuracy is < 1 msec. From Rajan Gill (2016-11-19). * sched/task: task_restart() test not supported on SMP systems. This is not fully implemented (2016-11-19). * This commit adds a new internal interfaces and fixes a problem with three APIs in the SMP configuration. The new internal interface is sched_cpu_pause(tcb). This function will pause a CPU if the task associated with 'tcb' is running on that CPU. This allows a different CPU to modify that OS data stuctures associated with the CPU. When the other CPU is resumed, those modifications can safely take place. The three fixes are to handle cases in the SMP configuration where one CPU does need to make modifications to TCB and data structures on a task that could be running running on another CPU. Those three cases are task_delete(), task_restart(), and execution of signal handles. In all three cases the solutions is basically the same: (1) Call sched_cpu_pause(tcb) to pause the CPU on which the task is running, (2) perform the necessary operations, then (3) call up_cpu_resume() to restart the paused CPU (2016-11-20). * task_restart: Make sure new task starts with pre-emption disabled and not in a critical section (2016-11-21). * Fix a typo in a spinlock macro (2016-11-21). * Spinlocks: Added capability to provide architecture-specific memory barriers. This was for i.MX6 but does not help with the SMP problems. It is still a good feature (2016-11-21). * Remove a assertion condition that appears to rarely cause false-alarm assertions. Teported by Petteri Aimonen (2016-11-21). * The examples/qencoder app was trying to init the encoder by a direct call into the board, cheating in a local header to declare the normally unavailable function prototype. From Sebastien Lorquet (2016-11-22). * configs: All QE encoder files. Last change made timer hard-coded to 3. Make configurable (2016-11-22). * configs: Remove all traces of the no-longer existent ARCHBUTTONS example. Remove all button configurations that depended on the obsoleted ARCHBUTTON example (2016-11-22). * nucleo-l476rg: Add better selection of timer (2016-11-22). * implementation of dumpgpio for stm32l4, was required for pwm debug. From Sebastien Lorquet (2016-11-22). * SMP: Add logic to avoid a deadlock condition when CPU1 is hung waiting for g_cpu_irqlock and CPU0 is waitin for g_cpu_paused (2016-11-22). * Misoc: Add timer driver. From Ramtin Amin (2016-11-22). * Misoc: Add commits and warnings about missing caculation of the timer reload value (2016-11-22). * SAM3/4: Name of method is now setcallback, not sethandler (2016-11-22). * sam4s-xplained-pro/nsh: Configuration uses old, improper timer interface. CONFIG_TIMER disabled in configuration. (2016-11-22). * sam4s-xplained-pro: Remove obsolete timer initialization logic (2016-11-22). * Misoc LM32: Make system timer configurable via CONFIG_USEC_PER_TICK. From Ramtin Amin (2016-11-23). * LPC43xx: Add timer driver; configs/bambino-200e: Add support for timer driver. From Alan Carvalho de Assis (2016-11-23). * SMP: Fix backward condition in test (2016-11-23). * ARMv7-A SMP: Add a little logic to signal handling (2016-11-24). * Misoc LM32: Add signal handling logic. From Ramtin Amin (2016-11-24). * SMP: Add spin_trylock(). Use this in conditions where other CPUs need to stopped but we cannot call enter_critical_section (2016-11-24). * Fix for F1 RTC Clock, tested on F103. From Maciej Wójcik (2016-11-25). * SMP: Fix yet another potential deadlock (2016-11-25). * Enable CONFIG_RTC in the hymini-stm32v/nsh2 (kitchensink) config. From Maciej Wójcik (2016-11-26). * This adds support for keeping i.MX6 inter-processor communication data in a non-cached address region (2016-11-26). * i.MX6: Disable non-cached region support. Add SCU register definitions (2016-11-26). * i.MX6: Add some controls to enable SMP cache coherency in SMP mode (2016-11-26). * ARMv7-A: Fix some SCU SMP logic (2016-11-26). * ARMv7-A/i.MX6: Modify handling of the SMP cache coherency configuration so that it is identical to the steps from the TRM. Makes no differenct, however (2016-11-27). * The Smoothie project needs to compile C++ inside config/boardname/src/ to use with High Priority Interruption, then I modified the board configs Makefile to support it. It works fine for the first time compilation, but if we execute "touch config/boardname/src/Pin.cxx" and execute "make" it will not detect that Pin.cxx was modified. I think there is some other place I should modify, but I didn't find it. From Alan Carvalho de Assis (2016-11-27). * ARMv7-A/i.MX6 SMP: Move SMP coherent cache setup to earlier in initialization of CPUn, n>0 (2016-11-27). * ARMv7 GIC: SGIs are non-maskable but go through the same path as other, maskable interrupts. Added logic to serialize SGI processing when necessary (2016-11-27). * sched_note: Extend OS instrumentation to include some SMP events (2016-11-27). * sched_note: Add spinlock instrumentation; In SMP configurations, select to log only notes from certain CPUs (2016-11-28). * Misoc LM3: Add Misoc Ethernet driver. Integrate network support into configs/misoc/hello. Remove configs/misoc/include/generated directory. I suppose the intent now is that this is a symbolic link? DANGER! This means that you cannot compile this code with first generating these files a providing a symbolic link to this location! From Ramtin Amin (2016-11-28). * Add tools/showsize.sh (2016-11-28). * configs/misoc: Add a sample directory containing generated sources. This is really only useful for performing test builds. You really must generate the Misoc architecture for a real-life build. From Ramtin Amin (2016-11-28). * sched_note: Permit spinlock and critical section notes in in-memory buffer iff sched_not_get() interfaces is disabled (2016-11-28). * STM32 DAC: Fix shift value whenever there are is a DAC2 and, hence, up to three interfaces. From Marc Rechté (2016-11-29). * Back out a debug change that was included in commit (2016-11-29). * i.MX6: Don't output the alphabet if CONFIG_DEBUG_FEATURES is not set (2016-11-29). * Misoc LM32: Add logic to flush/invalidate caches. From Ramtin Amin (2016-11-29). * drivers/net/: Adapt all Ethernet drivers to work as though CONFIG_NET_MULTIBUFFER were set. Remove all references to CONFIG_NET_MULTIBUFFER (2016-11-29). * stm32_otghshost: if STM32F446 increase number of channels to 16. From Janne Rosberg (2016-11-30). * usbhost_composite: Fix end offset in usbhost_copyinterface(). From Janne Rosberg (2016-11-30). * usbhost_cdcacm: Add CDC_SUBCLASS_ACM and CDC_PROTO_ATM to supported class and proto.

From Sebastien Lorquet (2016-12-01). * boardctl: Add new boardctl() command ,BOARDIOC_NX_START, to start the NX server as a kernel thread (2016-12-01). * GPDMA driver for the LPC43xx. The GPDMA block is basically the same as the LPC17xx. Only the clock configuration is different and LPC43xx has four different DMA request sources, where LPC17xx has only two. From Alan Carvalho de Assis (2016-12-01). * Remove RGMP and RGMP drivers (2016-12-02). * i.MX6: Add an untested SPI driver taken directly from the i.MX1 port (2016-12-02). * Eliminate CONFIG_NO_NOINTS. There is no longer any support for interrupt level processing of the network stack. Lots of files changed -> lots of testing needed (2016-12-03). * Fix DEBUGASSERT() in group_signal.c. From Masayuki Ishikawa (2016-12-04). * Add support for the SAM5CMP-DB board. From Masayuki Ishikawa (2016-12-04). * SAM3/4: Add SMP support for the dual-core SAM4CM. From Masayuki Ishikawa (2016-12-04). * C Library: Allow option to enable IP address conversions even when the IP address family is not supported (2016-12-04). * SSD1306: Fix errors in SPI mode configuration. From Gong Darcy (2016-12-04). * SAMA5 does not build when executing from SDRAM before board frequencies are not constant. Rather, the bootloader configures the clocking and we must derive the clocking from the MCK left by the bootloader. This means lots more computations. This is untested on initial commit because I don't have a good PWM test setup right now (2016-12-04). * Olimex-LPC1766-STK: Enable procfs in NSH configuration. Automount /proc on startup (2016-12-05). * SAM4CMP-DB: Add hooks to auto-mount the procfs file system on startup in board bring-up logic (2016-12-05). * Remove all references to BOARDIOC_PWMSETUP and board_pwm_setup() (2016-12-05). * Remove all references to BOARDIOC_ADCSETUP and board_adc_setup() (2016-12-05). * Added Timers 2-5 and control of SAI and I2S PLLs.

Added missing bits definitions, Used stm32F469 and stm32f446 bit definitions, Removed unsed header file. From David Sidrane (2016-12-05). * Remove BOARDIOC_CAN_INITIALIZE. CAN initialization is now done in the board initialization logic just like every other device driver (2016-12-06). * STM32F7: Allow the config to override the clock edge setting. From David Sidrane (2016-12-06). * For Cortex-A9, should also set ACTLR.FW in SMP mode to enble TLB and cache broadcasts. Does not fix SMP cache problem (2016-12-07). * sched notes: Add additional note to see if/when CPU is started in SMP mode (2016-12-07). * EFM32: Fix a compilation error. From Pierre-noel Bouteville (2016-12-07). * pthreads: Add pthread_cleanup_push() and pthread_cleanup_pop() (2016-12-08). * BUGFIX:STM32F427 was rebooting. Over reached family. From David Sidrane (2016-12-08). * Add pthread_setcanceltype() and pthread_testcancel() (2016-12-09). * Added STM32F469 RAM size and deliberated STM32F446 size.

From David Sidrane (2016-12-09). * LPC43xx SD card: Correct pin configuration options needed for SD card pins. From Alan Carvalho de Assis (2016-12-09). * pthread_mutex_destroy(): Fix an error in destroying a mutex which can occur after a pthread has been canceled while holding the mutex (2016-12-09). * Add support for cancellation points (2016-12-09). * Forgot to add some files in the last commit (2016-12-10). * Correct some default font IDs. From Pierre-Noel Bouteville (2016-12-10). * task_delete() now obeys all cancellation point semantics (2016-12-10). * Add task_setcancelstate(), task_setcanceltype(), and task_testcancel(). These are non-standard interfaces analogous to the correponding pthread_ interfaces that provide cancellation controls for tasks (2016-12-10). * i.MX6 interrupt handling: Additional logic needed to handle nested interrupts when an interrupt stack is used (2016-12-13). * SAMV7 MCAN: Prevent Interrupt-Flooding of ACKE when not connected to CAN-BUS. An Acknowledge-Error will occur every time no other CAN Node acknowledges the message sent. This will also occur if the device is not connected to the can-bus. The CAN-Standard declares, that the Chip has to retry a given message as long as it is not sent successfully (or it is not cancelled by the application). Every time the chip tries to resend the message an Acknowledge-Error-Interrupt is generated. At high baud rates this can lead in extremely high CPU load just for handling the interrupts (and possibly the error handling in the application). To prevent this Interrupt-Flooding we disable the ACKE once it is seen as long we didn't transfer at least one message successfully. From Frank Benkert (2016-12-13). * i.MX6: Remove non-cached, inter-cpu memory region. Not a useful concept (2016-12-13). * minnsh Configurations: Remove minnsh configurations and support logic: up_getc() and lowinstream. This was an interesting exercise to see just how small you could get NuttX, but otherwise it was not useful: (1) the NSH code violated the OS interface layer by callup up_getc and up_putc directly, and (2) while waiting for character input, NSH would call up_getc() which would hog all of the CPU. Not a reasonable solution other than as a proof of concept (2016-12-13). * Calypso Boards: Remove all Calypso board configurations (2016-12-13). * Calypso: Remove Calypso architecture support and support for Calypso SERCOMM driver (2016-12-13). * ESP32 core v2: Two changes (1) flushes the UART TX buffer in the esp32 serial shutdown routine. The ROM bootloader does not flush the FIFO before handing over to user code, so some of this output is not currently seen when the UART is reconfigured in early stages of startup. And changes the openocd config file's default flash voltage from 1.8V to 3.3V. This is not necessary right now, but may save some hard-to-debug moments down the track (3.3V-only flash running at 1.8V often half-works and does weird things...). From Angus Gratton (2016-12-14). * Xtensa ESP32: Add missing ENTRY() and RET() macros in C callable assembly language. At one time I though the that the ESP32 support the CALL0 ABI. I was mistaken so there may be a few more like this (2016-12-14). * Xtensa ESP32: Fix a couple of bugs associated with handling of CPU interrupts (2016-12-14). * Xtensa ESP32: Fix several build-related issues associated with vector section (2016-12-15). * Xtensa ESP32: Fix missing CALL0 ABI condition (2016-12-15). * Xtensa EPS32: Make sure that all C callable assembly functions includes ENTRY prologue and RET epilogue (2016-12-15). * Xtensa ESP32: Fix windowspill register handling + Use r6, not r2 when passing paramters with call4 (2016-12-16). * Xtensa ESP32: Use r6, not r2 when passing paramters with call4 (2016-12-16). * Xtensa ESP32: Correct a logic problem the prevented dumping the IDLE thread's stack on an assertion (2016-12-16). * Xtensa ESP32: Fix some missing SMP logic (2016-12-16). * Xtensa ESP32: Basically a redesign of the interrupt dispatch logic (2016-12-16). * Xtensa ESP32: Level 1 interrupts should return via RFE (2016-12-17). * Xtensa ESP32: One register getting clobber on context save (2016-12-17). * STM32 F7: Fix some STM32F7 copy paste errors. From David Sidrane (2016-12-17). * CDC/ACM Device Class: uart_ops_s portion of cdcacm will not be initalized with correct functions if CONFIG_SERIAL_DMA is lit (2016-12-17). * Xtensa ESP32: Using wrong register to disable interrupts (2016-12-17). * Xtensa ESP32: Fix clobbered a9 in co-processor context save/restore (2016-12-17). * Xtensa ESP32: Need to clone some logic for synchronous context switch. Window spill logic in the conmon restores logic is inappropriate in this context (2016-12-17). * sscanf(): Add scansets to the scanf function. Enabled CONFIG_LIBC_SCANSET option. From Aleksandr Vyhovanec (2016-12-17). * Xtensa ESP32: Fix context save logic when called in window ABI configuration. Add an IDLE stack. Don't depend on the mystery stack received from the bootloader (2016-12-18). * Xtensa ESP32: Need to spill registers to memory as the last dying action before switching to a new thread (2016-12-18). * ESP32 Serial: Add logic to prevent infinite loops in interrupt handler (2016-12-18). * Xtensa ESP32: Automatically mount /proc at start-up (2016-12-19). * Xtensa ESP32: Corrects timer initialization and timer input frequency (2016-12-19). * Tiva PWM: Support PWM_PULSECOUNT feature for TI tiva. From Young.Mu (2016-12-20). * Xtensa ESP32: Missing prologue/epilogue macros on C callable function (2016-12-20). * Xtensa ESP32: Update APP CPU startup logic to match current Expressif example code. Fix errors APP CPU startup (2016-12-20). * fs/procfs: Fix procfs status for SMP case (2016-12-20). * Xtensa ESP32: Clock frequency is different if running from IRAM or is booting from FLASH. This is a booltloader issue (2016-12-20). * Xtensa ESP32: Basic port is function in both single CPU and dual CPU SMP configurations. There is an NSH configuration for each CPU configuration (2016-12-21). * STM32 F4: Merge in support for the Olimex STM32 P407 board (2016-12-21). * Xtensa ESP32: Add an OS test to verify the port (2016-12-22). * Xtensa ESP32: Corrects a problem with dispatching to signal handlers: Cannot vector directly to the signal handling function as in other ABIs under the Xtensa Window ABI. In that case, we need to go through a tiny hook when performs the correct window call (call4) otherwise registers will be scrambled in the signal handler (2016-12-22). * SAMV7 CAN: Make delete_filter functions more robust. From Frank Benkert (2016-12-23). * Xtensa ESP32: Add stack checking logic (2016-12-23). * sched note: record ID enumeration now results on constant values; ID values do not change with configuration. This makes writing post-processing software much easier (2016-12-24). * STM32 F3: Forgot to update chip.h for STM32F303x[BC]'s 4 ADCs (2016-12-24). * STM32 F4: Allow dma in 1 bit mode in STM32F4xxx. From David Sidrane (2016-12-24). * termios.h: Fix CRTSCTS define to include input and output flow. From Lorenz Meier (2016-12-26). * SMP: Enforce this rule: Tasks which are normally restored when sched_unlock() is called must remain pending (1) if we are in a critical section, i.e., g_cpu_irqlock is locked , or (2) other CPUs still have pre-emption disabled, i.e., g_cpu_schedlock is locked. In those cases, the release of the pending tasks must be deferred until those conditions are met (2016-12-26). 7.20 2017-03-08 Gregory Nutt * i.MX6 SMP/NSH configuration: Enable examples/smp test (2016-12-27). * SMP: There were certain conditions that we must avoid by preventing the release of the pending tasks while withn a critical section. But this logic was incomplete; there was no logic to prevent other CPUs from adding new, running tasks while on CPU is in a critical section. This commit corrects this. This is matching logic in sched_addreadytorun to avoid starting new tasks within the critical section (unless the CPU is the holder of the lock). The holder of the IRQ lock must be permitted to do whatever it needs to do (2016-12-27). * i.MX6: Fix clearing GPT status register. From Masayuki Ishikawa (2016-12-28). * SMP: Make checks for CPU lock set more robust. There are certains conditions early in initialization on during interrupt handling where things need to be done a little differently (2016-12-28). * sched_cpulocked: Avoid use of spinlock. That has been reported to cause a deadlock (2016-12-28). * SMP: Fix a gap where we may try to make modifications to the task lists without being in a critical sections. That permits concurrent access to the tasks lists and many subtle problems. This fix just remains in the critical section throughout the operation (and possible until the task is restore in the event of a context switch). Makes a big difference in stability (2016-12-28). * SMP: Move sharable function to common file as irq_cpu_locked(). Use irq_cpu_locked() in sched_unlock(). Use irq_cpu_locked() in sched_removereadytorun() and sched_setpriority(). Use irq_cpu_locked() in sched_mergepending() (2016-12-29). * Add configuration support for builds with Ubuntu under Windows 10 (2017-01-01). * Add support for Tom Thumb small mono-space font. From Alan Carvalho de Assis (2017-01-03). * Alternative way to encode font spacing for Tom Thumb font (2017-01-04). * Graphics: Initial separation of font cache from graphics/nxterm. Now in libnx/nxfronts where it can be shared with other grapics applications (2017-01-05). * Font cache: Fix a reference counting issue: count not be initialized when font cache created. Fix initialization of a semaphore. Enforce mutually exclusive access to the font cache Replace fixed-size array with variable size link list. Font cache in libnx needs to use context-specific memory allocators (2017-01-06). * Add debug assertion in libdtoa to catch attempts to use floating point output formats from within an interrupt handler. That will cause assertions or crashes downstream because __dtoa will attempt to allocate memory. From Pierre-noel Bouteville (2017-01-06). * procfs: Correct to snprintf-related errors in fs_procfsproc.c. Resolves issue #24 (2017-01-07). * STM32F429i Discovery: Add support for NxWM on STM32F429i-Disco board. From Alan Carvalho de Assis (2017-01-07). * STM32F429i-DISCO: Enable keyboard input in nxwm configuration (2017-01-07). * STM32F429i-DISCO: Change NxWM cursor character from 137 (graphics block) to 95 (underscore). NxWM is configured to use a 7-bit character set so 137 is not a valid character code (2017-01-07). * NX server: Correct message queue names. Should not be at /dev, but rather relative to /var/mqueue (2017-01-08). * NxWM configurations. If using a 7-bit character set, then the cursor character cannot be 137 (graphic block). Use 95 (underscore) instead (2017-01-08). * packed_struct replaced by begin_packed_struct and end_packed_struct. From Aleksandr Vyhovanec (2017-01-09). * sched_note: Fix spinlock instrumentation. From Masayuki Ishikawa (2017-01-12). * SMP: Fix an error in critical section logic when performing a context switch from an interrupt handler. The g_cpu_irqset bit was not being set for the CPU so other CPUs did not know about the critical section (2017-01-13). * Kinetis: Added support for CHIP_MK60FN1M0VLQ12 chip. From Maciej Skrzypek (2017-01-13). * Kinetis: Fixed wrong MCG VDIV calculation on new NXP K60. From Maciej Skrzypek (2017-01-13). * Kinetis Serial: Fixed compile error when UART5 is selected. From Maciej Skrzypek (2017-01-13). * Kinetis: Need to set HAVE_UART_DEVICE when UART4 is selected. From Maciej Skrzypek (2017-01-13). * Kinetis MCG: Wrong FRDIV set in MCG_C1. From Maciej Skrzypek (2017-01-13). * Kinetis: New K60 has no Flex memory. From Maciej Skrzypek (2017-01-13). * In all implementations of _exit(), use enter_critical_section() vs. disabling local interrupts (2017-01-13). * i.MX6: Corrects behavior of last SMP patch with i.MX6 (2017-01-13). * SMP Signals: Fix some SMP signal delivery logic. Was not handling some critical sections correctly and was missing logic to signal tasks running on other CPUs (2017-01-14). * STM32F103 Minimum: Add support for nRF24 on STM32F103-Minimum board. From Alan Carvalho de Assis (2017-01-15). * Kinetis: Add support for K64/K66 RTC lower half driver. From Neil Hancock (2017-01-17). * Networking: Fixed some issues that prevented ipv6 to work with ipv4 enabled. From Pascal Speck (2017-01-18). * STM32 Oneshot: Fix logic so that it can support multiple oneshot timers (2017-01-18). * STM32L4: Port fix for multiple oneshot timers from STM32. Also fixes a few issues with original STM32 implementation (2017-01-18). * SAM3/4: Add support for ATSAM4S4C. From Wolfgang Reißnegger (2017-01-18). * Math library: Leverage optimized ARM functions from BSD license ARM file (2017-01-19). * Math library optimatizations for FPU only apply to ARMv8 which is not yet supported (2017-01-20). * Move optimized ARM memcpy functions from arch/arm/src/ to libc/machine/. This is necessary for the PROTECTED and KERNEL build modes. Otherwise, memcpy() will be built in to kernel space and not accessible to applications (2017-01-20). * libc: Fix ARMv7-A/R memcpy assembly (2017-01-20). * ARM memcpy(): Use DWord vs. HWord offset. ARM 32-bit instructions must be aligned to DWord boundaries and this gives us more range in the jump tables (2017-01-20). * Fix a compile error: in sched_cpuload.c:Line136, the variables ts and secs are not defined if CONFIG_CPULOAD_ONESHOT_ENTROPY = 0. However, these variables are used regardless of CONFIG_CPULOAD_ONESHOT_ENTROPY at lines~180:onwards. From rg (2017-01-22). * CPU load: Correct computation of the nominal period to use when the source is a oneshot timer (2017-01-22). * Kernel Modules: Module initializer may now return a symbol table (2017-01-22). * Modules: Extend the module interface so that we can access symbols exported by the module (2017-01-22). * Shared Libraries: In the FLAT build mode, kernel modules may be used to provide minimal shared library functionality (2017-01-22). * Shared libraries: Add a non-standard dllfnc.h function to set the symbol table (2017-01-23). * Olimex-stm32-p407: Add a NSH protected build configuration; Enable procfs/ in all configurations (2017-01-23). * SMP: Fix timer related issues: Round robin and sporadic scheduling were only being performed for tasks running on the CPU that processes the system timer interrupt. Similary, CPU load measurements were only be processed for running on the CPU that receives the sampling interrupt (2017-01-23). * STM32 F7: Added missing ARCH_HAVE_RESET for F7. From David Sidrane (2017-01-23). * STM32: Add missing STM32_BKP_BASE. From David Sidrane (2017-01-23). * Configurations that enable OSTEST must not disable signals (2017-01-24). * Add missing sched_note_*() calls to sam4cm SMP functions (2017-01-24). * Fix return value if x is NaN. From Aleksandr Vyhovanec (2017-01-25). * MMCSD_SDIO: Only wait for card ejected if card detection is supported. From Alan Carvalho de Assis (2017-01-26). * LPC43 pinset definitions: Add more 1 bit to pinset to reach SFSCLK0-SFSCLK3. Remove PINCONFIG_DIGITAL. From Alan Carvalho de Assis (2017-01-26). * sched/modules: Add support for dependencies between modules (2017-01-27). * Back out use on inline functions to access 16-bit registers. The inline functions were a work-around for misbehaving compiler years and years ago. The mon standard macro-ized version should work just fine (2017-01-27). * Olimex STM32 P407: Add support for on-board microSD slot. Does not work... Currently all commands to the SD card timeout (2017-01-28). * libc/modlib: Add build a configuration logic for a shared module library (2017-01-29). * Module names are not needed in libc/modlib when the module library is used only for shared library support (2017-01-29). * Shared Libs: Implement module based shared libraries for the PROTECTED mode build (2017-01-29). * Typos withim mtd/ with Macronix MX25L. In NuttX/drivers/mtd/Make.defs letters X between M and 25 are missing. Noted by Oleg Evseev (2017-01-x30x). * SAME70-Xplained: Clone some recent SAMV71-XULT changes (2017-01-30). * Add capabilities() method to SDIO interface. Remove CONFIG_SDIO_WIDTH_D1_ONLY. That should not be a global propertie, but rather a capability/limitation of single slot when there may be multiple slots (2017-01-31). * Removed dmasupported() method from the SDIO interface. That is now a bit in the capability set (2017-01-31). * STM32F7 SDMMC: Add support for single bit operation on SDMMC2 (2017-01-31). * STM32F103-Minimum: Fix a compile error. CONFIG_STM32_TICKLESS_ONESHOT_TIMER is only defined in TICKLESS mode. Somebody has been hand editing .config files (2017-01-31). * Timer logic: Add private function prototypes to eliminate a warning; Functions should not be inline because the may recurse (2017-01-31). * STM32F7 SDMMC: Make sure that all SDMMC configuration variables begin with STM32F7_; Eliminate CONFIG_SDMMC1/2_DMA altogether. Does not appear to be used (2017-01-31). * STM32F429-DISCO: Move some board initialization logic that is not usable because it lacks the configuration options to make it so (2017-01-31). * Cancellation points: Fix some backward logic in conditional compilation (2017-02-02). * Soft links: Add an implementation of readlink() (2017-02-03). * inode_find: Now takes struct inode_desc_s type as input. That structure includes some data storage. It was used within inode_find(), but that means that the life of the data was the life of inode_find(). That data must persist longer. It is now provided by the caller so that the life of the data persists for the entire life of the caller (2017-02-05). * tools/noteinfo.c: A hack tool that I use to analyze some sched_note output. Needs a home and may be useful to others (2017-02-05). * Pseudo File System: Add support for soft links in the top-level psuedo file system (2017-02-05). * Updates to Kinetis SDHC driver. From Marc Rechté (2017-02-06). * SDIO interface: Handle all possible DMA combinations in all SDIO drivers (2017-02-07). * up_timer_initialize() is named incorrectly. The prefix should be the architecture name, not up_ since it is private to the architecture. up_timerisr() is similarly misnamed and should also be private since it is used only with the xyz_timerisr.c files (2017-02-07). * MCG defines are based on the MCG feature configuration. We define the bits as a common set of names. This means that an index may be added to a name i.e. LOCK is LOCK0 as that is the superset name. From David Sidrane (2017-02-07). * Fixes illdefined BOARD_FR_DIV with BOARD_FRDIV from MCG. Original BOARD_FR_DIV was never used - that is a good thing because the value ws defined shifted and the code also shifted it. From David Sidrane (2017-02-07). * Added MCG settings that are defiend on the K64 SoC. Added BOARD_MCG_C2_FCFTRIM and BOARD_MCG_C2_LOCRE0 to configure the MCG_C2 register cleanup of some comments. From David Sidrane (2017-02-07). * Better granualarity and errno checking of the board's MCG settings. Allow for complete MCG_C2 definition from the boart.h file. Moved #ifdef out of code by setting default values. Allow for individule bit setting in MCG_C2 for BOARD_EXTCLOCK_MCG_C2, BOARD_MCG_C2_FCFTRIM, BOARD_MCG_C2_LOCRE0. Added range and sanity checking. From David Sidrane (2017-02-07). * Cosmetic changes from review of last PR (2017-02-07). * C library: Remove comments blocks before empty sections (2017-02-08). * C Library: Add a very limited, first step implementation of setvbuf(). This is a collaborative effort. Alan Carvalho de Assis did the initial prototype (2017-02-08). * setvbuf: Add support for configuration of line buffering (2017-02-08). * Bamboo-200E: Add netnsh configuration. From Alan Carvalho de Assis (2017-02-08). * USBMSC: Always set LUN readonly flag. From Wolfgang Reißnegger (2017-02-08). * drivers/lcd: ssd1306_configspi() must have global scope (2017-02-09). * SIM: Add readlink and setvbuf to nuttx-names.dat (2017-02-09). * setvbuf: Add support for disabling I/O bufferin (2017-02-09). * setvbuf: Fix some compile errors in first build of logic to enable/disable buffering (2017-02-09). * C Library: Clean-up buffer selections in Kconfig (2017-02-09). * sem_open(): Fix a compiler error introduced with the setvbuf() changes (2017-02-09). * MMC/SD SDIO: Some drivers need to start DMA before sending CMD24 and some AFTER. From Alan Carvalho de Assis (2017-02-09). * Kinetis SDHC driver fixes. From Marc Rechté (2017-02-09). * Bambino-200E: Use .elf extension on all executables. From Alan Carvalho de Assis (2017-02-09). * Kinetis: Add support for K66 family. From David Sidrane (2017-02-09). * Created a kinetis MCG versioning scheme pulled in by Kinetis chip.h The motivations is to version the IP blocks of the Kinetis K series family of parts. This added versioning and configuration features for the Kinetis MCG IP block. It is envisioned that in the long term as a chip is added. The author of the new chip definitions will either find the exact configuration in an existing chip define and add the new chip to it Or add the MCG feature configuration #defines to the chip ifdef list in arch/arm/include/kinetis/kinetis_mcg.h In either case the author should mark it as "Verified to Document Number:" taken from the reference manual. The version KINETIS_MCG_VERSION_UKN has been applied to most all the SoCs in the kinetis arch prior to this commit. The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12, All K64 and K66 which not have Verified MCG configurations. From David Sidrane (2017-02-09). * Kinetis chip Adding K66 and including MCG versioning. This includes arch/arm/include/kinetis/kinetis_mcg.h to bring in the MCG versioning and defines the KINETIS_K66 family for the added SoCs: --------------- ------- --- ------- ------- ------ ------ ------ ----- PART NUMBER CPU PIN PACKAGE TOTAL PROGRAM EEPROM SRAM GPIO FREQ CNT FLASH FLASH --------------- ------- --- ------- ------- ------ ------ ------ ----- MK66FN2M0VMD18 180 MHz 144 MAPBGA 2 MB — — KB 260 KB 100 MK66FX1M0VMD18 180 MHz 144 MAPBGA 1.25 MB 1 MB 4 KB 256 KB 100 MK66FN2M0VLQ18 180 MHz 144 LQFP 2 MB — — KB 260 KB 100 MK66FX1M0VLQ18 180 MHz 144 LQFP 1.25 MB 1 MB 4 KB 256 KB 100 From David Sidrane (2017-02-09). * STM32: Fixes the bkp reference counter issue. From David Sidrane (2017-02-09). * STM32F7: Fixes the bkp reference counter issue. From David Sidrane (2017-02-09). * C Library: Add setbuf() which is a trivial wrapper around setvbuf() (2017-02-09). * tools/mkconfig.c: Add logic to keep all of the buffering options in sync (2017-02-10). * VFS rename: Fix issues with rename to subdirectories and some softlink issues (2017-02-11). * Add logic to VFS rename: If target of rename exists and is a directory, then the source file should be moved 'under' the target directory. POSIX also requires that if the target is a file, then that old file must be deleted (2017-02-11). * rename: An inode with no operations should be treated like a directory for the purposes of rename (2017-02-12). * rename(): Correct more issues. (1) Move to the root directory in the pseudo file system, (2) Fix path naming calculation when the path is the root directory of a mounted file system, and (3) dont't do the rename if the source and destination of the rename are the same (2017-02-12). * Add basic fstat() support (2017-02-12). * Add fstat support to binfs (2017-02-12). * fstat: Add fstat() support to romfs (2017-02-12). * fstat: Add fstat() support to unionfs (2017-02-12). * I found an issue inside the cp15_coherent_dcache function in file, arch/arm/src/armv7-r/cp15_coherent_dcache.S. The "mcr CP15_BPIALLIS(r0)" instruction is used for invalidating entire branch predictor. But the problem is, since this is the generic code and can be called on any armv7-r architecture based CPU's. It is a problem, if this instruction is called in uni processor configuration. Because, BPIALLIS (c7, 0, c1, 6) instruction is only added as part of the "Multiprocessing Extensions" (As per ARM® Architecture Reference Manual /ARMv7-A and ARMv7-R edition) So in my opinion, this instruction should be under SMP configuration. In non-SMP configuration this instruction could become undefined. From Manohara HK (2017-02-13). * fstat: Add fstat() support to tmpfs (2017-02-13). * fstat: Add fstat() support to nxffs (2017-02-13). * fstat: Add fstat() support to nfs (2017-02-13). * NFS: Use clock_gettime() instead of deprecated gettimeofday() (2017-02-13). * fstat: Add fstat() support to FAT. From Alan Carvalho de Assis (2017-02-13). * ROMFS: stat() and fstat() should always indicate that directories are executable (2017-02-13). * Kinetis SDHC - Enable clock after selected. From David Sidrane (2017-02-14). * Kinetis SPI and I2C are 0 based. The K whole family line has max 4 or each. But the supported parts have the maximums listed below: K46 and K66 3 SPI SPI0-SPI2 K46 and K66 4 I2C I2C0-I2C3 From David Sidrane (2017-02-10). * Add support for NXP Freedom-k66f development board. From David Sidrane (2017-02-14). * Kinetis: Define Alternate addresses for IP blocks in both AIPS0 & AIPS1. Added ALT version of RNGA, FTM2, DAC0 as a facility to later define secondary access via AIPS1 to these peripherals. From David Sidrane (2017-02-14). * Kinetis: Add support for K66.

From Alan Carvalho de Assis (2017-02-14). * procfs: Most stat() implementations were not initializating the st_atime, st_ctime, and st_mtime fields (2017-02-15). * Kinetis Support RMII clock source select. This defined the RMII clock source select bits and allows the selection to be made via Kconfig. From David Sidrane (2017-02-15). * Kinetis PWM: Add FTM3 to PWM. From David Sidrane (2017-02-15). * Kinetis:Freedom-K66F uses ENET_1588_CLKIN as RMII clock. From David Sidrane (2017-02-15). * Fix for SAMv7 SPI: DLYBS value was calculated, but never written to any registers. This led to incorrect timings on the bus. From Michael Spahlinger (2017-02-16). * C library: Add swab() (2017-02-16). * C library: Add strtoimax and strtoumax (2017-02-16). * C library: Add ffs(), rindex(), an index(). Add strings.h. Move strcasecmp, strncasecmp, bzero, bcmp, and bcopy to where they belong in strings.h.h, not string.h. bzero, bcmp, and bcopy are legacy functions; the contemporary counterparts should be used instead (2017-02-16). * Allow board to configure HSE clock in bypass-mode. This is needed to enable HSE with Nucleo-F746ZG board. From Jussi Kivilinna (2017-02-17). * C library: Add fstatfs(); fix a reference counting error in fstat() (2017-02-17). * Update cwchar. Add cwctype (2017-02-17). * Add setbuf and setvbuf to cstdio (2017-02-17). * Port STM32L4 SAI driver from MDK (2017-02-17). * STM32L4: Bring power management logic from Motrola MDK into NuttX (2017-02-18). * STM32L4: Bring LPTIM driver in from the Motorola MDK (2017-02-18). * drivers/sensors: Add driver for the ST L3GD20 3 axis gyro. From raiden00 (2017-02-19). * config/stm32f429i-disco: Add support for the L3GD20 driver. From raiden00 (2017-02-19). * STM32L4 COMP: Port from Motorola MDK (2017-02-19). * Add twr-k64f120m config and fix some ENET related problems. From Marc Rechté (2017-02-19). * STM32 F7: stm32_allocateheap: allow use DTCM memory for heap. STM32F7 has up to 128KiB of DTCM memory that is currently left unused. This change adds DTCM to main heap if CONFIG_STM32F7_DTCMEXCLUDE is not enabled. From Jussi Kivilinna (2017-02-20). * This should resolve issue #30: Audio Tone Generator and PWM Multiple Output Channel options. I don't actually have a setup to verify it, however (2017-02-20). * drivers/tone.c: 50% duty needs to be expressed a a fixed precision number (2017-02-21). * Kinetis: Created a kinetis SIM versioning scheme pulled in by Kinetis chip.h. The motvations is to version the IP blocks of the Kinetis K series family of parts. This added versioning and configuration features for the Kinetis SIM IP block. It is envisioned that in the long term as a chip is added. The author of the new chip definitions will either find the exact configuration in an existing chip define and add the new chip to it Or add the SIM feature configuration #defines to the chip ifdef list in arch/arm/include/kinetis/kinetis_sim.h In either case the author should mark it as "Verified to Document Number:" taken from the reference manual. The version KINETIS_SIM_VERSION_UKN has been applied to most all the SoCs in the kinetis arch prior to this commit. The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12, All K64 and K66 which not have Verified SIM configurations. From David Sidrane (2017-02-21). * Created a kinetis PMC versioning scheme pulled in by Kinetis chip.h. The motivation is to version the IP blocks of the Kinetis K series family of parts. This added versioning and configuration features for the Kinetis PMC IP block. It is envisioned that in the long term as a chip is added. The author of the new chip definitions will either find the exact configuration in an existing chip define and add the new chip to it Or add the PMC fature configuration #defines to the chip ifdef list in arch/arm/include/kinetis/kinetis_pmc.h In either case the author should mark it as "Verified to Document Number:" taken from the reference manual. The version KINETIS_PMC_VERSION_UKN has been applied to most all the SoCs in the kinetis arch prior to this commit. The exceptions are the CONFIG_ARCH_CHIP_MK60FN1M0VLQ12, CONFIG_ARCH_CHIP_MK20DXxxxVLH7 All K64 and K66 have been verified PMC configurations. From David Sidrane (2017-02-22). * Kinetis: kinetis_clockconfig uses the correct ACKISO. ACKISO is located in the PMC_REGSC on the majority of the Kinetis SoCs. With the exception of the MK40DXxxxZVLQ10 where ACKISO is located in LLWU_CS (2017-02-22). * Kinetis: Refactor you use SIM_SOPT2_PLLFLLSEL, added warning. The warning has been added because: SIM_SOPT2_PLLFLLSEL is a clock selection that may feed many clock subsystem: USB, TPM, SDHCSRC, LPUARTSRC. Therefore, there needs to be a global board level setting to select the source for SIM_SOPT2_PLLFLLSEL and then derive all the sub selections and proper fractions/divisors for each modules clock. From David Sidrane (2017-02-22). * Add support to QEncoder on STM32F103Minimum board. From Alan Carvalho de Assis (2017-02-23). * Olimex STM32 p407: Add external SRAM support. Unfortunately not usable or testable unless you also disable the serial console (2017-02-23). * drivers/spi/Kconfig: There is too much SPI in the configuration menu; SPI Driver Support menu is empty. From Maciej Wójcik (2017-02-23). * Kinetis: SIM add paramiterized SIM_CLKDIVx_xxFRAC|DIV macros. The makes for cleaner board definitions. From David Sidrane (2017-02-23). * kinetis_enet.c add #define for number of loops for auto negotiation to complete. From Marc Rechté (2017-02-23). * STM32F4 Discovery: Fix issues with QEncoder support. From Alan Carvalho de Assis (2017-02-23). * sigtimedwait: When timer expires, up_unblock_task() is called. This is okay in the single CPU case because interrupts are disable in the timer interrupt handler. But it is insufficient in the SMP case. enter_ and leave_critical_section() must be called in order to manage spinlocks correctly (2017-02-23). * Fix QEncoder driver, based on STM32L4 driver. From Alan Carvalho de Assis (2017-02-23). * STM32 QEncoder. Enable clocking to the timer on QE setup; disable clock on QE teardown (2017-02-23). * Kinetis: Extend clockconfig to support SOPT2_PLLFLLSEL and SIM_CLKDIV3. A board.h file can now specify the: 1) BOARD_SOPT2_PLLFLLSEL to select the output of the SIM_SOPT2 MUX from: MCGFLLCLK, MCGPLLCLK, USB1PFD, and IRC48MHZ. 2) If it defines BOARD_SIM_CLKDIV3_FREQ then it must define BOARD_SIM_CLKDIV3_PLLFLLFRAC and BOARD_SIM_CLKDIV3_PLLFLLDIV which wil be used to cpnfigure SIM_CLKDIV3 [PLLFLLFRAC, PLLFLLDIV]. From David Sidrane (2017-02-23). * Kinetis serial: Added configurable 1|2 stop bits. HAVE_SERIAL_CONSOLE -> HAVE_UART_CONSOLE to be consistent with HAVE_LPUART_CONSOLE naming. From David Sidrane (2017-02-23). * Kinetis: Add LPUART serial driver and Clock configuartaion to freedom-k66f board. Pin out LPUART0 for testing. Define BOARD_SOPT2_PLLFLLSEL ti select MCGPLLCLK. Define BOARD_SIM_CLKDIV3_FREQ etal to provide BOARD_LPUART0_FREQ. From David Sidrane (2017-02-25). * QEncoder: Add mechanism to assure that architecture-specific IOCTL commands do not overlap (2017-02-25). * include/nuttx/analog: Add an ioctl.h header file to coordinate analogic driver IOCTL commands (2017-02-25). * CAN: Add infrastructure to assure that all CAN IOCTL commands are uniquely numbered (2017-02-25). * Wireless and TSC: Add infrastructure to assure that all IOCTL commands are uniquely numbered (2017-02-25). * Add basic support for the STM32F334 and Nucleo F334R8 board. From Mateusz Szafoni (2017-02-16). * SAM3/4: GPIO bit numbering typo fixes. From Wolfgang Reißnegger (2017-02-26). * Add SDCard support over SPI on STM32F103-Minimum board. From Alan Carvalho de Assis (2017-02-26). * option to enable Memory Card debug output was hidden with SD cards connected through SPI. From Maciej Wójcik (2017-02-27). * Kinetis serial: Fixed up_rxint - did not disable the RX interuppts. There was an OR where and AND NOT was needed. From David Sidrane (2017-02-27). * Kinetis:Add the configuring SIM_CLKDIV2[USBFRAC, USBDIV] in kinetis_clockconfig. If a board.h provides BOARD_SIM_CLKDIV2_FREQ it will configure the SIM_CLKDIV2 based on the additional provided BOARD_SIM_CLKDIV2_USBFRAC and BOARD_SIM_CLKDIV2_USBDIV. The reason for doing this globaly is that the output the SIM_CLKDIV2 divisor may be also used for other IP blocks in future configurations (as is done for SIM_CLKDIV3). From David Sidrane (2017-02-27). * Kinetis: Refactor clocking in kinetis_usbdev. (1) Removed SIM_CLKDIV2[USBFRAC, USBDIV] setting as it is now, done in kinetis_clockconfig, (2) Use BOARD_USB_CLKSRC to select the clock source to the USB block, (3) Removed CONFIG_TEENSY_3X_OVERCLOCK from the driver as the board.h will now provide BOARD_SIM_CLKDIV2_USBDIV and BOARD_SIM_CLKDIV2_USBFRAC to the kinetis_clockconfig. From David Sidrane (2017-02-27). * Kinetis: Use BOARD_xxxx to drive system clocking: (1) Shifted the clock speed of MK20DX128VLH5 to 48 Mhz to be able to uses USB. (2) Set BOARD_OUTDIV3 to 0 - there is no BOARD_OUTDIV3 on a MK20DX128VLH5 or K20DX256VLH7, (3) Added BOARD_SOPT2_PLLFLLSEL and BOARD_SOPT2_FREQ along with settings for BOARD_SIM_CLKDIV2_USBFRAC and BOARD_SIM_CLKDIV2_USBDIV base on the BOARD_SOPT2_FREQ. From David Sidrane (2017-02-27). * Kinetis: Define uart and lpuart versions of [early]serialinit. Add serial init to centralize UART/LPUART management. Use kinetis_ not up_ where arch specific. Defined kinetis_[lp]uart_[early]serialinit to facilitate bring up both UARTs and LPUARTs as devices and a console. Support ordering and merging of serial devices names. From David Sidrane (2017-02-27). * Adapt more drivers to utilize the IRQ argument feature (2107-02-28). * irq_attach() and type xcpt_t. irq_attach now accepts a argument that will be provided to the interrupt handler when the interrupt ocurrs. This affects many files by replace ad hoc parameter passing logic with a standardized approach. From Mark Schulte (2017-03-01). * Fix open() a block device with CONFIG_DISABLE_PSEUDOFS_OPERATIONS=y. From Masayuki Ishikawa (2017-03-01). * net/: Fixed a nullptr-dereference on iob_clone. From Pascal Speck (2017-03-01). * configs/: All functions that used to return an xcpt_t old handler value, not return NULL. The oldhandler value is no longer useful with the recent changes to the interrupt argument passing (2017-03-02). * arch_phy_irq: Now returns int instead of xcpt_t oldhandler. The oldhandler is useless after the changes to the interrupt argument. Also access an argument for the PHY interrupt. phy_notify.c driver changed to exploit new interrupt argument passing (2017-03-02). * STM32/F7/L4: EXTI PVD function no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * STM3 L4: EXTI COMP function no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * STM32/F7/L4: EXTI ALARM function no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * Add support to USB Device on STM32F103-Minimum board. From Alan Carvalho de Assis (2017-03-02). * Kinetis GPIO: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * STM32 Ethernet: Need two work structures so that pending poll work is not lost when an interrupt occurs (2017-03-02). * Kinetis-L GPIO: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * PIC32MX: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * PIC32MZ: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * STM32 L4: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * Tiva: Pin IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * board_button_irq: Button IRQ logic no longer returns the xcpt_t oldhandler. There value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * stm32_gpiosetevent: GPIO IRQ logic no longer returns the xcpt_t oldhandler. This value is useless and dangerous after the recent changes to interrupt argument passing (2017-03-02). * Implements support for smaller interrupt tables as described at http://www.nuttx.org/doku.php?id=wiki:howtos:smallvectors . This is largely the work of Mark Schulte. However, I have made several changes to match with the Wiki document. If you like the change, thanks go to Marc. For any errors you can blame me (2017-03-03). * Experimental change to STM32 Ethernet driver a success. Porting change to all other Ethernet drivers (2017-03-03). * FS: Don't build block driver proxy if PSEUDOFS_OPERATIONS are disabled (2017-03-04). * drivers/net: Add framework for serialization in the case where multiple low-priority work queues are used (2017-03-04). * net/drivers/skeleton.c: Back out serialization changes of the last commit. They are not necessary in the skeleton.c example because the calls to net_lock() at the beginning of each worker function will enforce serialization (2017-03-04). * STM32F33XX DAC, OPAMP, COMP and ADC headers. From Mateusz Szafoni (2017-03-04). * STM32 F7 SDMMC: Use new interrupt argument facility (2017-03-05). * stm32f33xxx: Add HRTIM header file. From Mateusz Szafoni (2017-03-05). * sendfile(): Fix error introduced with commit ff73be870e38959b0aaee5961dc47b4b58dc2d86. Noted by Maciej Wójcik (2017-03-05). * Kinetis: Eliminate warning when USE_EARLYSERIALINIT is not defined (2017-03-05). * STM3210E-EVAL: Eliminte a warning.

Correct type of return value (2017-03-05). * STM32F103 Minimum: Eliminate warning stm32_usbdev.o givne twice in same rule (2017-03-05). * STM32 OTGHS host: stm32_in_transfer() fails and returns NAK if a short transfer is received. This causes problems from class drivers like CDC/ACM where short packets are expected. In those protocols, any transfer may be terminated by sending short or NUL packet. From Janne Rosberg. Adapt Janne Rosberg's patch to STM32 OTGHS host to OTGFS host, and to similar USB host implementations for STM32 L4 and F7 (2017-03-07). * usbhost_cdcacm: Fix tx outbuffer overflow and remove now invalid assert. From Janne Rosberg (2017-03-07). 7.21 2017-06-05 Gregory Nutt * tools/kconfig2html: Need to increase the maximum number of default values (2017-03-08). * C library: Add strerror_r() (2017-03-08). * C Library: Add wcstoull(), swprintf(), wcstod(), wcstof(), wcstol(), wcstold(), wcstoul(), wcstoll() functions. Add mbsnrtowcs() and wcsnrtombs() (just returning success). Add mbtowc() and wctomb() to C++ std namespace. From Alan Carvalho de Assis (2017-03-08). * Kinetis: Fixed GPIO _PIN_OUTPUT_LOWDRIVE swapped with _PIN_OUTPUT_OPENDRAIN. From David Sidrane (2017-03-08). * Ensure interrupts are back on BEFORE running code dependant on clock_systimer. From David Sidrane (2017-03-08). * Enable compilation of libc++ same way as uClibc++.

From Andreas Bihlmaier (2017-03-09). * Add missing PINCONF_INBUFFER in several places of lpc4310203050_pinconfig.h. From Andreas Bihlmaier (2017-03-09). * Rename LPC43_GPDMA_GLOBAL_CONFIG (already slipped previous commit C file); fix GPDMA_CONTROL_SBSIZE_*, improve usability of GPDMA_CONTROL_{S,D} macros. From Andreas Bihlmaier (2017-03-09). * Fix errors in LPC43 SCT and SGPIO headers. From Andreas Bihlmaier (2017-03-09). * Fix logic error in lpc43_adc.

From Andreas Bihlmaier (2017-03-09). * Use correct macro for irqid (fortunately both point to LPC43_IRQ_EXTINT+18). From Andreas Bihlmaier (2017-03-09). * Actually write modified value to register. From Andreas Bihlmaier (2017-03-09). * Increase number of supported PWM channels from 4 to 6. From Andreas Bihlmaier (2017-03-09). * Fix as5048b by adding missing frequency parameter. From Andreas Bihlmaier (2017-03-09). * Kinetis: Allow Board to add Pullups on SDHC lines. From David Sidrane (2017-03-09). * EZ80F910200KITG: Missing support logic in configs/Kconfig (2017-03-09). * Olimex-STM32-P407: Update USB host support (2017-03-09). * Olimex STM32 P407: USB host support for USB FLASH sticks is now supported in the base nsh configuration (2017-03-09). * STM32, STM32 F7, and STM32 L4: Back out part of 3331e9c49aaaa6dcc3aefa6a9e2c80422ffedcd3. Returning immediately in the case of a NAK makes the Mass Storage Class driver unreliable. The retry/timeout logic is necessary. This implementation tries to implement a compromise: If a NAK is received after some data is received, then the partial data received is returned as with 3331e9c49aaaa6dcc3aefa6a9e2c80422ffedcd3. If if a NAK is received with no data, then no longer returns the NAK error immediately but retries until data is received or a timeout occurs. Initial testing indicates that this fixes the issues the MSC. However, I have concerns that if multiple sectors are read in one transfer, there could be NAKs between sectors as well and, in that case, then change will still cause failures (2017-03-09). * STM32F2: Add USB OTG HS support for stm32f20xxx cores. From Simon Piriou (2017-03-09). * Remove all references to arch_usbhost_initialize(). That was incorrectly called from apps/examples/hidkbd. That is violation of the OS interfacing rules and will no longer be supported. USB host should be initialized as part of the board bring-up logic was with any other devices and should not involve illegal calls from applications into the OS (2017-03-09). * STM32, STM32 F7, STM32 L4: OTG host drivers: Do not do data toggle if interrupt transfer is NAKed. Sugested by webbbn@gmail.com (2017-03-09). * apps/examples/usbterm is gone because it can be configured to perform an illegal call into the OS. Remove all traces of CONFIG_EXAMPLES_USBTERM* and all of the illegal device support (2017-03-09). * Save elapsed time before handling I2C in stm32_i2c_sem_waitstop(). This patch follows the same logic as in previous fix to stm32_i2c_sem_waitdone(). It is possible that a context switch occurs after I2C registers are read but before elapsed time is saved in stm32_i2c_sem_waitstop(). It is then possible that the registers were read only once with "elapsed time" equal 0. When scheduler resumes this thread it is quite possible that now "elapsed time" will be well above timeout threshold. In that case the function returns and reports a timeout, even though the registers were not read "recently". Fix this by inverting the order of operations in the loop - save elapsed time before reading registers. This way a context switch anywhere in the loop will not cause an erroneous "timeout" error. From Freddie Chopin (2017-03-10). * pthreads: Fix pthread_mutexattr_init(). It was not initializing the protocol field when priority inheritance is enabled (2017-03-10). * Priority inheritance: When CONFIG_SEM_PREALLOCHOLDERS==0, there is only a single, hard-allocated holder structure. This is problem because in sem_wait() the holder is released, but needs to remain in the holder container until sem_restorebaseprio() is called. The call to sem_restorebaseprio() must be one of the last things the sem_wait() does because it can cause the task to be suspended. If in sem_wait(), a new task gets the semaphore count then it will fail to allocate the holder and will not participate in priority inheritance. This fix is to add two hard-allocated holders in the sem_t structure: One of the old holder and one for the new holder (2017-03-10). * STM32, STM32 F7, and STM32 L4: Clone Freddie Chopin's I2C change to similar STM32 I2C drivers. From David Sidrane (2017-03-10). * Priority Inversion fixes: Initalization. From David Sidrane (2017-03-10). * configs: Add Particle Photon board support. From Simon Piriou (2017-03-10). * tools/testbuild.sh: Add debug option (-d) (2017-03-10). * multiple fixes in nrf24l01 driver: (1) signal POLLIN if there is already data in the FIFO, (2) send ETIMEDOUT to userspace after 2 seconds if TX IRQ was not received, (3) handle FIFO overflow, (4) handle invalid pipes/empty FIFO, and (5) multiple cosmetics (missing static, duplicate define, missing \n). From Leif Jakob (2017-03-10). * STM32 F33 ADC: Correct bad definitions of base addresses; Fix naming collision by changing colliding STM32_ADC12_BASE to STM32_ADC12_CMN_BASE (2017-03-10). * photon: Add iwdg timer support. From Simon Piriou (2017-03-11). * photon: Add usb otg hs support and usbnsh app. From Simon Piriou (2017-03-11). * photon: Add LEDs and BUTTONS support. From Simon Piriou (2017-03-11). * As discovered by dcabecinhas. This fix assume the 8 byte alignment options for size stack size or this will overwrite the first word after TOS.

From Simon Piriou (2017-03-11). * STM32: Propagate STM32 F2 changes of last PR to STM32 F4 and F7 OTGHS (2017-03-11). * STM32 OTG HS: A little research reveals that only the F2 RCC initialization set the OTGHSULPIEN bit and Photon is the only F2 board configuration that uses OTG. Therefore, we can simplify the conditional logic of the last PR. Negative logic was used (#ifndef BOARD_DISABLE_USBOTG_HSULPI) to prevent bad settings in other configurations. But giveh these facts, the preferred positive logic now makes more sense (#ifdef BOARD_ENABLE_USBOTG_HSULPI) (2017-03-11). * STM32: OTG host implementations of stm32_in_transfer() must obey the polling interval for the case of isochronous and interrupt endpoints (2017-03-12). * Photon: Add basic support for wlan chip. From Simon Piriou (2017-03-12). * Networking: Add registration support for integrated ieee80211 wireless drivers. Rename CONFIG_IEEE802154 to CONFIG_WIRELESS_IEEE8021514 following the convention of including the location of the configuration variable as a part of its name (2017-03-12). * If whence is SEEK_END, the file offset shall be set to the size of the file plus offset. Noted by eunb.song@samsung.com (2017-03-13). * Move IEEE 802.11 wireless IOCTLs from include/nuttx/net/ioctl to include/nuttx/wireless/wireless.h.

From Anthony Merlino (2017-03-15). * Integrate use of new wireless debug macros. Replace ad hoc debug macros. Convert obsolete dbg() macros to current info(), warn(), err() macros (2017-03-15). * sem_holder: Fixes improper restoration of base_priority in the case of CONFIG_SEM_PREALLOCHOLDERS=0. The call to sem_restorebaseprio_task context switches in the sem_foreachholder(sem, sem_restoreholderprioB, stcb); call prior to releasing the holder. So the running task is left as a holder as is the started task. Leaving both slots filled thus failing to perform the boost/or restoration on the correct tcb. This PR fixes this by releasing the running task slot prior to reprioritization that can lead to the context switch. To faclitate this, the interface to sem_restorebaseprio needed to take the tcb from the holder prior to the holder being freed. In the failure case where sched_verifytcb fails it added the overhead of looking up the holder. There is also the additional thunking on the foreach to get from holer to holder->tcb. An alternate approach could be to leve the interface the same and allocate a holder on the stack of sem_restoreholderprioB copy the sem's holder to it, free it as is done in this pr and and then pass that address sem_restoreholderprio as the holder. It could then get the holder's tcb but we would keep the same sem_findholder in sched_verifytcb. From David Sidrane (2017-03-15). * ARM: Remove redundant interrupt stack coloring.

Erase a sector from the second bank cause the bit 4 of SNB being set but never unsed, so trying to erase a sector from the first bank was acually eraseing a sector from the second bank. From José Roberto de Souza (2017-03-22). * STM32: Make up_progmem thread safe. Writing to a flash sector while starting the erase of other sector have a undefined behavior so lets add a semaphore and syncronize access to Flash registers. But for the semaphore to work it needs to be initialized so each board needs call stm32_flash_initialize() on initialization, so to avoid runtime problems it is only using semaphore and making it thread safe if initialized, after all boards starts to call stm32_flash_initialize() we can remove the boolean and the check. From José Roberto de Souza (2017-03-22). * STM32: Add workaround for flash data cache corruption on read-while-write.

From Aleksandr Vyhovanec (2017-03-24). * I needed to use DS3231, I remember that in past it worked ok, but now for stm32f4xx is used another driver (chip specific, stm32f40xxx_i2c.c) and DS3231 driver doesn't work. After investigating a problem I found that I2C driver (isr routine) has a few places there it sends stop bit even if not all messages are managed. So, e.g., removing stm32_i2c_sendstop (#1744) and adding stm32_i2c_sendstart after data reading helps to make DS3231 working.

This is copied from stm32l4. Tested on STM32F746ZG board. From Juha Niskanen (2017-03-29). * STM32 RNG: Fix semaphore initial value and disable priority inheritance. From Juha Niskanen (2017-03-29). * Fix an assertion noted by Jussi Kivilinna. This was a consequence of the recent robust mutex changes. If robust mutexes are selected, then each mutex that a thread takes is retained in a list in threads TCB. If the thread exits and that list is not empty, then we know that the thread exitted while holding mutexes. And, in that case, each will be marked as inconsistent and the any waiter for the thread is awakened. For the case of pthread_mutex_trywait(), the mutex was not being added to the list! while not usually a fatal error, this was caught by an assertion when pthread_mutex_unlock() was called: It tried to remove the mutex from the TCB list and it was not there when, of course, it shoule be. The fix was to add pthread_mutex_trytake() which does sem_trywait() and if successful, does correctly add the mutext to the TCB list. This should eliminated the assertion (2017-03-29). * 6loWPAN: IEEE802.15.4 MAC driver will need a special form of the network device structure to manage fragmentation of the large packet into frames (2017-03-29). * wireless/ieee802154: Adds MAC character driver structure.

Fix by making inlined caller to have internal linkage as well. From Juha Niskanen (2017-03-30). * Add entropy pool and strong random number generator. Entropy pool gathers environmental noise from device drivers, user-space, etc., and returns good random numbers, suitable for cryptographic use. Based on entropy pool design from *BSDs and uses BLAKE2Xs algorithm for CSPRNG output. Patch also adds /dev/urandom support for using entropy pool RNG and new 'getrandom' system call for getting randomness without file-descriptor usage (thus avoiding file-descriptor exhaustion attacks). The 'getrandom' interface is similar as 'getentropy' and 'getrandom' available on OpenBSD and Linux respectively. From Jussi Kivilinna (2017-03-30). * Change STM32 tickless to use only one timer. From Konstantin Berezenko (2017-03-30). * drivers/sensors: Add driver for ST HTS221 humidity sensor. From Juha Niskanen (2017-03-30). * HTS221 driver: Modify to use new interrupt parameter passing hooks (2017-03-31). * drivers/sensors: Add driver for ST LPS25H pressure sensor.

Tested with earlier version of NuttX; with current version checked that it compiles. Via Juha Niskane (2017-03-31). * Add user-space networking stack API (usrsock). User-space networking stack API allows user-space daemon to provide TCP/IP stack implementation for NuttX network. Main use for this is to allow use and seamless integration of HW-provided TCP/IP stacks to NuttX. For example, user-space daemon can translate /dev/usrsock API requests to HW TCP/IP API requests while rest of the user-space can access standard socket API, with socket descriptors that can be used with NuttX system calls.

From Jussi Kivilinna (2017-04-06). * STM32F7: Default CONFIG_STM32F7_DMACAPABLE to 'n'. STM32F7 does not have CCM RAM but DTCM, so this option does not need to enabled. DTCM RAM is DMA-able through CPU AHBS bus. From Jussi Kivilinna (2017-04-06). * STM32F7: Fix UART7 and UART8 IFLOWCONTROL options. From Jussi Kivilinna (2017-04-06). * STM32F7: Add warning for RXDMA + IFLOWCONTROL combination. Combination of RXDMA + IFLOWCONTROL does not work as one might expect. Since RXDMA uses circular DMA-buffer, DMA will always keep reading new data from USART peripheral even if DMA buffer underruns. Thus this combination only does following: RTS is asserted on USART setup and deasserted on shutdown and does not perform actual RTS flow-control. Data loss can be demonstrated by doing long up_mdelay inside irq critical section and feeding data to RXDMA+IFLOWCONTROL UART. From Jussi Kivilinna (2017-04-06). * sim/sixlowpan: Now supports apps/examples/udpblaster too (2017-04-06). * SAMV7: Watchdog: Fix Forbidden Window Value. According the Datasheet the WDD Value is the lower bound of a so called Forbidden Window and to disable this we have to set the WDD Value greater than or equal to the WDV Value. This seems to be a bug in the datasheet. It looks like we have to set it to a greater value than the WDV to really disable this Thing. When triggering the Watchdog faster than the (very slow) clock source of the Watchdog fires, this Forbidden Window Feature resets the System if WDD equals to WDV. This Changeset disables the Forbidden Window by setting the WDD Value to the Maximum (0xfff) Value possible. From Frank Benkert (2017-04-06). * RTC: Add interface for check if RTC time has been set. New interface allows checking if RTC time has been set. This allows to application to detect if RTC has valid time (after reset) or should application attempt to get real time by other means (for example, by launching ntpclient or GPS). From Jussi Kivilinna (2017-04-06). * 6loWPAN: Add network IOCTL support to set the node address (2017-04-06). * EFM32 I2C: Fix timeout calculation.

This is very incomplete on the initial commit (2017-04-08). * Buttons: Change return value of board_buttons() and the type of btn_buttonset_t to uint32_t so that more than 8 buttons can be supported (2017-04-09). * Add support for NuttX controlled LEDS and for board_initialize. Separate initialization logic to stm32_bringup.c so that in initialization can occur either through board_initialize() or through board_app_initialize(). Same as with most other newer board configurations (2017-04-09). * net procfs: Some long lines were being generated that cause buffer-related problems and corrupted output (2017-04-09). * stm32 COMP: Logic in stm32_comp.h must be configured on CONFIG_STM32_COMP or otherwise it causes an error via #error on every platform without COMP support (2017-04-09). * Photon: Add logic to automatically mount the procfs file system on startup. Fix some LED-related configuration conflicts (2017-04-09). * Buttons: Correct some comments left after last button-related change: 32- vs 8-bit bit set (2017-04-09). * pthread: Use cancel cleanup handlers in rwlock. From Juha Niskanen (2017-04-10). * STM32F7: serial: disallow broken configuration combination of CONFIG_STM32F7_FLOWCONTROL_BROKEN=y and CONFIG_SERIAL_IFLOWCONTROL_WATERMARKS not set. From Jussi Kivilinna (2017-04-11). * STM32F7: serial: do not stop processing input in SW flow-control mode. From Jussi Kivilinna (2017-04-11). * STM32XX: Fix Pending Register definition. From Alan Carvalho de Assis (2017-04-11). * Add logic to disable cancellation points within the OS. This is useful when an internal OS function that is NOT a cancellation point calls an OS function which is a cancellation point. In that case, irrecoverable states may occur if the cancellation is within the OS. From Juha Niskanen (2017-04-11). * Fix LLVM libc++ undefined reference to __cxa_guard_*. From Alan Carvalho de Assis (2017-04-11). * libc/netdb: in dns_query_callback, ret != -EADDRNOTAVAIL condition consumes error returns including EAGAIN in this case, dns query retransmission doesn't work.

From Anthony Merlino (2017-05-09). * drivers/serial: I discovered a problem in the file drivers/serial/serial.c concerning the function uart_close(…). In the case that a serial device is opened with the flag O_NONBLOCK the function uart_close(…) blocks until all data in the buffer is transmitted. The function close(…) called on an handle opened with O_NONBLOCK should not block. The problem occurred with a CDC/ACM device. From Stefan Kolb (2017-05-10). * mtd/config: erase block between block read and write. From Juha Niskanen (2017-05-10). * Moved LIS3DSH from the I2C-dependent block to the SPI-block to make Make.defs consistent with the driver (SPI only) and drivers/sensors/Kconfig. From Floxx (2017-05-10). * syslog: Add option to buffer SYSLOG output to avoid interleaving (2017-05-10). * syslog buffering: Use IOBs to buffer data, not an on-stack buffer (2017-05-10). * STM32L4: Add internal flash write support. From Juha Niskanen (2017-05-11). * When syslog message has addition characters after last new-line. With buffering those now get lost as vsyslog does not flush output after lib_sprintf. Additional trailing characters could be ANSI escape sequence to reset state that message setups. For example, macro here uses colors and resets state after actual message (including '\n'): With flushing added to vsyslog, then there is problem that next syslog line might come from other task before reset sequence, causing wrong line getting color. This could be avoided by not flushing on '\n' but only if IOB is full and/or at end of vsyslog. Would this make sense?. From Jussi Kivilinna (2017-05-11). * Syslog: Need inclusion of errno.h for fix building with CONFIG_SYSLOG_TIMESTMAP=y (2017-05-11). * mtd: Build RAMTRON and AT45DB drivers only if selected. From Juha Niskanen (2017-05-11). * mtd/config: Fix byte read interface test. From Juha Niskanen (2017-05-11). * mtd: Fix some unallocated and NULL pointer issues. rwb->wrflush and rwb->wrmaxblocks in rwbuffer could get unallocated values from ftl_initialize() in some configurations. Also fixes related assert: up_assert: Assertion failed at file:rwbuffer.c line: 643 that can happen with the following configuration: CONFIG_FTL_WRITEBUFFER=y CONFIG_DRVR_WRITEBUFFER=y # CONFIG_FS_WRITABLE is not set These problems are caused by CONFIG variable differences between the buffer layers. TODO: This is not a perfect solution. readahead support has similar issues. From Juha Niskanen (2017-05-11). * STM32L4: port stm32l4_serial_get_uart function from STM32F7. From Juha Niskanen (2017-05-12). * syslog: Avoid flushing syslog_stream buffer, if possible, until lib_vsprintf() completely parses the format. This assures that the flush will flush the entire output, even data that may potentially follow the linefeed. And, in that case, it cannot be interleaved with other devug output. Suggested by Jussi Kivilinna (2017-05-12). * syslog: There is yet another place where the output can get split. That is in syslog_dev_write(): It will break up the stream to insert a CR before the LF. This can that can be avoid be generating the CR-LF sequence in the buffer and then detecting and ignoring valid CR-LF sequences, rather than expecting syslog_dev_write() to insert the CR in this case. I don't like the idea that syslog_dev_write() still scans the entire output buffer to expand CR-LF sequence. This seems really wasteful, especially in this case where we can be sure that the is no CR or LF without a matching LF or CR. Bu, I think, the existing behavior in syslog_dev_write() must be retained because it is needed in other contexts (2017-05-12). * Bitbucket Issue 47: Some of last syslog changes needed to be condition on #ifdef CONFIG_SYSLOG_BUFFER in order to be built without syslog buffering enabled (2017-05-12). * Move CAN subsystem to its own directory and put device drivers there. From Alan Carvalho de Assis (2017-05-12). * locale.h: Add a bogus definition of locale_t. From (2017-05-12). * kinetis K66: Fixed TMP2_CH1 definition.

From David Sidrane (2017-05-13). * STM32F410: Add support for STM32F410. STM32F410 is a version of STM32F4 with 32 KB of RAM and 62 or 128 KB of flash. From Gwenhael Goavec-Merou (2017-05-13). * Kconfig/deconfigs: Add CONFIG_ARCH_TOOLCHAIN_GNU to indicate that the toolchain is based on GNU gcc/as/ld. This is in addition to the CPU-specific versions of the same definition (2017-05-13). * Remove CONFIG_ARM_TOOLCHAIN_GNU; replace with CONFIG_ARCH_TOOLCHAIN_GNU (2017-05-13). * Tiva I2C: Correct an error in conditional compilation (2017-05-13). * Kconfig: Rename CONFIG_ARM_TOOLCHAIN_IAR to CONFIG_ARCH_TOOLCHAIN_IAR (2017-05-13). * Move prototype for up_cxxinitialize() from nuttx/include/nuttx/arch.h to apps/include/platform/cxxinitialize.h (2017-05-13). * libc/wchar: Versions mbrlen and mbsrtowcs taken and adapted from FreeBSD code (at https://github.com/freebsd/freebsd/).

From Simon Piriou (2017-05-14). * TCP: Send RST if applicaiton 'unlistens()' before we complete the connection sequence (2017-05-14). * drivers: fix some bad NULL checks. From Juha Niskanen (2017-05-15). * drivers: rename newly introduced up_i2creset to I2C_RESET. From Juha Niskanen (2017-05-15). * TCP: An RST received during the 3-way handshake requires a little more clean-up (2017-05-15). * STM32 CAN: I had the problem that the transmit FIFO size (= actual elements in FIFO) was slowly increasing over time, and was full after a few hours. The reason was that the code hit the line "canerr("ERROR: No available mailbox\n");" in stm32_cansend, so can_xmit thinks it has sent the packet to the hardware, but actually has not. Therefore the transmit interrupt never happens which would call can_txdone, and so the size of the FIFO size does not decrease. The reason why the code actually hit the mentioned line above, is because stm32can_txready uses a different (incomplete) condition than stm32can_send to determine if the mailbox can be used for sending, and thus can_xmit forwards the packet to stm32can_send. stm32can_txready considered mailboxes OK for sending if the mailbox was empty, but did not consider that mailboxes may not yet be used if the request completed bit is set - stm32can_txinterrupt has to process these mailboxes first. Note that I have also modified stm32can_txinterrupt - I removed the if condition, because the CAN controller retries to send the packet until it succeeds. Also if the condition would not evaluate to true, can_txdone would not be called and the FIFO size would not decrease also. From Lederhilger Martin (2017-05-16). * drivers/bch: BCH character driver bch_ioctl() always returns -ENOTTY for DIOC_GETPRIV command. It should returns OK if DIOC_GETPRIV command succeeds. From EunBong Song (2017-05-16). * There can be a failure in IOB allocation to some asynchronous behavior caused by the use of sem_post(). Consider this scenario: (1) Task A holds an IOB.  There are no further IOBs.  The value of semcount is zero. Task B calls iob_alloc().  Since there are not IOBs, it calls sem_wait().  The value of semcount is now -1. (2) Task A frees the IOB.  iob_free() adds the IOB to the free list and calls sem_post() this makes Task B ready to run and sets semcount to zero NOT 1.  There is one IOB in the free list and semcount is zero. When Task B wakes up it would increment the sem_count back to the correct value. (3) But an interrupt or another task runs occurs before Task B executes.  The interrupt or other tak takes the IOB off of the free list and decrements the semcount.  But since semcount is then < 0, this causes the assertion because that is an invalid state in the interrupt handler. So I think that the root cause is that there the asynchrony between incrementing the semcount. This change separates the list of IOBs: Currently there is only a free list of IOBs. The problem, I believe, is because of asynchronies due sem_post() post cause the semcount and the list content to become out of sync. This change adds a new 'committed' list: When there is a task waiting for an IOB, it will go into the committed list rather than the free list before the semaphore is posted. On the waiting side, when awakened from the semaphore wait, it will expect to find its IOB in the committed list, rather than free list. In this way, the content of the free list and the value of the semaphore count always remain in sync (2017-05-16). * stm32_serial: Fix freezing serial port. Serial interrupt enable/disable functions do not disable interrupts and can freeze device when serial interrupt is received while execution is at those functions. Trivially triggered with two or more threads write to regular syslog stream and to emergency stream. In this case, freeze happens because of mismatch of priv->ie (TXEIE == 0) and actually enabled interrupts in USART registers (TXEIE == 1), which leads to unhandled TXE interrupt and causes interrupt storm for USART.

SIOCSIFADDR, SIOSLIFADDR, SIODIFADDR .. should not change the link state. From Sebastien Lorquet (2017-05-19). * drivers/wireless/ieee80211: Add support for AP scanning. From Simon Piriou (2017-05-21). * drivers/audio: Add cs43l22 audio driver STM32F4: Add I2S driver. From Taras Drozdovsky (2017-05-21). * This is based on a patch by Taras Drozdovsky. Basically, the delay that was added during the integration of the CDC/ACM host driver was interfering with streaming audio. That delay was put there to prevent build endpoints from hogging the system bandwidth. So what do we do? Do we hog the bandwidth or do we insert arbitrarity delays. I think both ideas such (2017-05-21). * Replace sprintf() with snprintf() in pipe.c. From Nobutaka Toyoshima (2017-05-22). * drivers/bch: Fix 'Missing Unlock' in bchdev_driver.c.
