0.1.0 2007-03-09 Gregory Nutt <gnutt@nuttx.org>
* Initial Release
* Support for Linux user mode simulation and TI
TMS320C5471 (Arm7) provided
0.1.1 2007-03-14 Gregory Nutt <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>

* Added mount() and umount()
* Fix bug in memcmp return value
* Fix errors in timeslice calculation (several places)
* Added missing irqrestore() in timer_deleteall().

* Added strspn() and strcspn()
0.2.6 2007-05-26 Gregory Nutt <gnutt@nuttx.org>
* 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).

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)

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

* 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.

* 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 <gnutt@nuttx.org>
* FAT FS now uses position variable in struct file. This simplifies operations

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.

0.3.16 2008-10-10 Gregory Nutt <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* arch/arm/src/lpc313x/lpc313x_usbdev.c: USB driver for the LPC313x
contributed by David Hewson.

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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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,

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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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/<board>/<config>/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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 Kinetics TWR-K60N512 board is
now functional.
* configs/twr-k60n512: Add Kinetics 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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.

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)

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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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/lpc32_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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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/<many>/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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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, lpc32, 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.

* 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:

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 <gnutt@nuttx.org>
* arch/arm/src/lpc17xx/lpc17_i2c.c: Interrupts were not being
re-enabled in the I2C initializeation function (2013-4-30).

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,

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)

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

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).

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).

peripheral Kconfig (2013-6-11).
* arch/arm/src/sam34/chip/sam4s_pinmap.h: Add SAM4S pin configuration
definitions (2013-6-11).
* arch/arm/src/sam34/sam4s_periphclks.h: Add macros to manage SAM4S
peripheral clocks (2013-6-11).
* configs/sam4s-xplained: Configuration builds error-free (2013-6-11).
* configs/sam4s-xplained/nsh: Added an NSH configuration for the
SAM4S Xplained board. Both the OS test and the NSH configurations
no execute error-free. Delay loops calibrated for both the SAM4L
and SAM4S boards (2013-6-12).
* Standardize on CONFIG_NSH_BUILTIN_APPS. 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 <gnutt@nuttx.org>
* 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).

(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,

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. This might have broken some things? (2013-6-17).
* drivers/mmcsd/mmcsd-spi.c: Driver need to make sure that the SPI mode
and data width are correct (2013-6-17).
* arch/arm/src/kinetis/kinetis_tsi.h: Corrections to the Kinetis
(2013-6-18)
* arch/arm/src/sam34/sam_spi.c: Fix SPI mode setting. In the SAM3/4
family, the clock phase control (CPHA) is inverted (NPHA) (2013-6-18).
* arch/arm/src/kl/chip/kl_tsi.h: Freescale KL25Z TSI register
definitions from Alan Carvalho de Assis (2013-6-18).
* configs/freedom-kl25z/src/kl_tsi.c: Example TSI driver for the
Freedom KL25Z board from Alan Carvalho de Assis (2013-6-18).
* arch/arm/src/sam34/sam_spi.c: Correct an incorrect pointer test.
Was checking if the wrong pointer was NULL (2013-6-18).

controlling SPI-related discrete inputs and outputs. 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. From Dave (ziggurat29, 2013-6-22).
* configs/sam4l-xplained/src/sam_slcd.c: LED1 segment LCD module is now
functional (2013-6-23).
* drivers/lcd/ssd1306.c and include/nuttx/lcd/ssd1306.h. Renamed
ug-2864hsweg01.c and .h to ssd1306.c and .h. Extended to support the
UG-2832HSWEG04 which is very similar and also based on the SSD1306
controller (2013-6-23).

support for reverse portrait mode from lessons learned with the
UG-2832HSWEG04. Untested changes! (2013-6-24).
* arch/arm/src/stm32/stm32_ccm.c and .h: Add support for a seperate CCM
heap. This may be useful for segregating allocations for CCM (which
cannot be used for DMA) from other allocations (that may be used used
for DMA) (2013-6-25).
* arch/arm/src/sam32/sam3u_gpio.h: Correct configuration of PIO pins
for SAM4S B and C peripherals (2013-6-26)
* configs/sam4s-xplained/src/sam_sram.c: Added support for on-board

multi-plexing definitions (2013-6-26).
* arch/arm/src/sam34/sam3x_gpio.h: Add SAM3X/3A gpio encoding
macros. These differ from the SAM3U only in because of the
6 PIOs: PIOA-PIOF (2013-6-26).
* configs/arduino-due: This is an empty directory now with only
a README file in it but this directory will eventually hold a port
for the Arduino Due (2013-6-26).
* arch/arm/src/sam34/Kconfig: Add SAM3X/3A peripherals to the SAM3/4
configuration logic (2013-6-26).
* arch/arm/src and include/ and configs/sam*/: Large rename of all
references to SPI with SPI0. This is because all other SAMs have
only SPI but the 3X/3A have SPI0 and SPI1 (2013-6-26).
* configs/arduino-due: Complete the basic board configuration and
integrate this into the configuration and build system. The Arduino
Due is now ready to begin test (2013-6-17).
* configs/arduino-due/nsh: Add an NSH configuration for the Arduino
Due. Both the OS test and NSH configuration are now functional
(2013-6-28).
* configs/arduino-due/src: Add support for the "L" LED (2013-6-28).
* arch/arm/src/sam34/sam_allocateheap.c: Clocking must be applied
to the SMC module for the 3X and 3A family in order for the NFC
SRAM to be functional (2013-6-28).
* arch/arm/src/sam34/sam3u_gpio.c: Need to disable write
protection before configuring PIO pins.
* configs/sam3u-ek/nsh: The touchscreen is now functional. The above
fix to the sam3u_gpio.c write protection also fixed the touchscreen
problem (2013-6-28).
* confgis/sam3u_ek/nxwm: Created a configuration for the NxWM
window manager for the SAM3U-EK board (2013-6-29).
* drivers/spi and include/nuttx/spi: New sub-directories to hold
SPI-related files. includes/nuttx/spi.h moved to include/nuttx/spi/.;
SPI-related Kconfig info moved from drivers/Kconfig to drivers/spi/kconfig
(2013-7-1).
* drivers/spi/spi_bitbang.c and include/nuttx/spi/spi_bitbang.h: Add
support for a generic bit-bang SPI driver. This checkout is the
common upper-half logic. Still missing the lower half (2013-7-1).
* include/nuttx/spi/spi_bitbang.c: This is the common lower-half bit-
bang SPI logic (2013-7-1).
* configs/arduino-due/src/sam_nsh.c and sam_mmcsd.c: Add NSH customize
initialization. If so configured, initialize the SPI bit bang
interface to the MMC/SD slot on the ITEAD shield (2013-7-1).
* fs/fs_mount.c: Fix compilation error if no file systems are enabled:
Change error to ERROR (2013-7-3).

(2013-7-7).
* arch/arm/src/stm32/stm32_otgfsdev.c: SourceForge bug #16: Fix
to the endpoint allocation logic. 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).

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).

(2013-7-22).
* arch/arm/src/sama5/sam_clockconfig.c: Add SAMA5 PLL configuration
logic (plus associated header files). Initiali checkin is for the
SAM3U which is very similar but needs to be verified (2013-7-22).
* arch/arm/src/sama5/sam_periphclks.h: Add macros to enable and
disable SAMA5 peripheral clocks (2013-7-22).
* arch/arm/src/sama5/sam_lowputc.c and sam_serial.c: Add support
for SAMA5 UARTs. Does not even compile as of initial checkin.
(2013-7-22).
* arch/arm/src/sama5/sam_gpio.c: Add GPIO configuration support
for the SAMA5. Still compilation issues. (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);

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 <gnutt@nuttx.org>
* 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).

* 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).

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).

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

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/<stm32-boards>:
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).

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 <gnutt@nuttx.org>
* 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).

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).

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). Use start-up configuration settings from

uip/uip_udpconn.c, uip/uip_udpinput.c: Changed the meaning of the
uip_*input functions. They now return success when a packet is
dropped; This is needed for the ENCX24J600 driver that must make
a decision to return the packet or not: It should not retry
dropped packets. 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).

being mapped. The mapping was getting overrwritten and the
framebuffer memory was ending up cacheable (2013-10-13).
* arch/arm/src/sama5/Kconfig, sam_lcdc.c, defconfig, and related files:
Remove options for obtaining framebuffer memory in other ways. That

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).

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).

2) sscanf() returns incorrect number of parsed numbers if some arguments
can't be parsed: sscanf("=2", "%u,%u,%u,%u",...)==1 instead of 0, and
3) using of char* instead of const char* in vsscanf function leads to
warnings from GCC (2013-10-21).

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

value was not being set, making the failure look like success. 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).

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. From
David Sidrane (2013-11-2).

* 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 <gnutt@nuttx.org>

(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

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

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).

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).

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).

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).

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).

("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 St<53>hn 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 <gnutt@nuttx.org>
* 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
<pid>/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).

cases where there wass some good argument to retain the ostest
configuration) (2014-2-28).

* configs/rgmp/x86/nsh: Configuration converted to use the
kconfig-frontends tools (2014-3-6)
* configs/rgmp/x86/helloxx: Configuration converted to use the
kconfig-frontends tools (2014-3-6)
* configs/rgmp/x86/cxxtest: Configuration converted to use the
kconfig-frontends tools. This completes the conversion of all
configurations to the newer format (2014-3-6)
* Removed the CONFIG_NUTTX_NEWCONFIG setting from every defconfig
file (2014-3-6).
* The legacy, manual configuration is no longer supported by the
NuttX build system. 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

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).

TM4C123G-Launchpad (2014-3-10).
* configs/sam4e-ek: Add basic board support for the SAM4E-EK board.
More work is needed. 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).

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

Jason Jiang (2014-3-15).
7.2 2014-04-29 Gregory Nutt <gnutt@nuttx.org>
* 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 St<53>hn (2014-3-24).
* net/netdev_ioctl.c and uip/uip_input.c: IGMP-related bug fixes
from Manuel St<53>hn (2014-3-24).

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).

from Bob Doiron needed to support PDC-based HSMCI DMA transfers
(2014-4-21).
* configs/sam4s-xplained-pro: Support for the SAM4S Xplained Pro
board from Bob Doiron (2014-4-21).
* configs/sam4s-xplained-pro: Added card detect (kind of broken
still); added proc/vfat mounting during init to save some typing.
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 <gnutt@nuttx.org>
* 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).

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).

* 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 Sami Pelkonen (2014-5-30).
* net/arp: Move arp related files from net/uip to net/arp. Files renamed
with arp_ prefix (2014-5-30).
* include/nuttx/net/arp.h and net/arp/arp_timer.c: Moved

for the lpcxpresso's rtc handler, adc, dac, timers, pwm and mcpwm
drivers. 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.

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. This
is an important bug fix for the SAMA5D3 and 4 when running out of
DRAM (2014-6-30).
* arch/arm/src/sama5/sam_pio.c: Another *critical* SAMA5D3 and 4 bug
fix: PIO clocking must be enabled for all input pins or else the
value that is read never changes. (2014-6-30).
* net/: Many more functions renamed to follow new modularization of
the networking code. This is part of an ongoing repartitioning
effort and there is still more to be done. There will be no additional
notations in this ChangeLog until the renaming is complete (2014-6-30).

parts of uip.h to net.h. Renamed the rest of uip.h to ip.h. Removed
all includes of uip.h; added includes of ip.h wherever needed.
Tried to fix problems of the now missing sneak inclusions because
uip.h was removed. There are probably a few of these that were
missed! (2014-7-4).

could this have worked before? (2014-7-7).
* SAMA5D3/4 PIO Interrupts: Correct a typo in
arch/arm/src/sama5/sam_pio.h that could disable PIO interrupt support
if only PIOE interrupts were enabled (2014-7-7).
* SAMA5D4 PIO Interrupts: Macro SAM_PION_VBASE is not defined for the
SAMA5D4 and must be replaced with a table lookup (2014-7-7).
* configs/sam*: Fix some cloned errors in SAM GPIO interrupt setup
(1014-7-7).
* arch/arm/src/sama5/Kconfig and sam_allocateheap.c: Add a
configuration option to reserve DRAM for a framebuffer when executing
out of DRAM. This optional was available before when executing out of
NOR, but needs to work a little differently in this case (2014-7-7).
* arch/arm/src/sama5/sam_lcd.c and chip/sam_lcdc.h: Adapt the SAMA5D3
LCDC driver to work with the SAMA5D4 which has no hardware cursor
(2014-7-8).
* configs/sama5d4-ek: Add options to support an LCD (2014-7-7).
* arch/arm/src/sama5/sam_twi.c: Now support the up_i2creset() method
(2014-7-9)
* drivers/input/mxt.c: Use i2c_reset() if it thinks that the bus
might by hung (2014-7-9).
* arch/arm/src/sama5/sam_pio.c/.h: Add a new interface
sam_pio_forceclk() that can be used to force PIO clocking on. I am
afraid I was too conservative with PIO clocking in the initial design;
this is the price (2014-7-9).
* arch/arm/src/sama5/sam_twi.c: Use sam_pio_forceclk() so that we can
read the current state of an open-drain output in the TWI reset logic
(2014-7-9).
* arch/arm/src/sama5/sam_pio.c/.h: Fix a typo in Schmitt trigger
configuration; Configure pin as a a vanilla input first so that final
pin configuration is more read-able (i.e., easier to debug)
(2014-7-9).
* drivers/input/mxt: The maXTouch driver works! (2014-7-10).
* configs/sama5d4-ek: The TM7000 LCD works! (2014-7-10).
* configs/sama5d4-ek/NxWM: Add an NxWM configuration (2014-7-10).
* drivers/mtc_rwbuffer.c (and others): Add an MTD layer that will add
read-ahead or write buffering to any MTD driver (incomplete) (2014-7-11).
* arch/arm/src/lpc17xx/lpc17_ethernet.c: Comment out an assertion that
is reported to fire inappropriately. From Max (2014-7-11).
* drivers/mtd (mostly): Addition rwbuffer interfaces should not be
enabled unless they are needed; if rwbuffer support is enabled, it
should not be unconditionally enabled in SMART and FTL (2014-7-11).
* libnx/nxglib/nxglib_colorcmp.c and include/nuttx/nx/nxglib.h: New
utility to compare two colors (2014-7-11).
* graphics/Kconfig and nxbe/nxbe_configure.c: The initial background
color is now configurable (2014-7-11).
* graphics/nxmu/nxmu_server.c and nxsu/nx_setbgcolor.c: Don't change
the background if the color did not really change (2014-7-11).
* arch/arm/src/sama5/sam_ldc.c and sama5d4-ek/include/board.h: Back
out the delay kludge. The actual fix to the LDC instability was to
drive the LCD at 2xMCK instead of 1xMCK (2013-7-12).
* drivers/input/mxt.c: Fix an error in the state machine (2014-7-12).
* drivers/input/mxt.c: Add thresholding so that "move" reports are not
generated unless there is a significant change in the reported
position (2014-7-12).
* SAMA5D4-EK MXT: The maXTouch should be able to handler an I2C
frequency of 400KHz. Valid interrupts should occur only on the
falling edge of the ~CHG signal (2014-7-12).
* SAMA5D3x-EK: Use larger icons in NxWM configuration instead of
scaling (2014-7-14).
* Graphics: Rename CONFIG_NX_MOUSE to CONFIG_NX_INPUT, then add
CONFIG_NX_XYINPUT_MOUSE and CONFIG_XYINPUT_TOUCHSCREEN (2014-7-16).
* drivers/input/mxt.c: Fix error in threshoold test... backward
logic (2014-7-16).
* graphics/nxconsole/nxcon_scroll.c: Fix scrolling in the NxConsole
for the case of the framebuffer device. In this case, the logic
for clearing the vacated region at the bottom was missing so garbage
up from the last, uncleared line (2014-7-17).
* drivers/audio/wm8904.c/.h and include/nuttx/audio.wm8904.h: Framework
for a WM8904 audio driver. The initial driver check-in is simply Ken
Pettit's VS1053 driver forced to compile with only WM8904 definitions
(2014-7-18).
* configs/sama5d4-ek/src/sam_wm8904.c: Add logic to configure and
initialize the WM8904 audio CODEC (2014-7-17).
* arch/arm/src/sama5/sam_sckc.c/.h and chip/sam_sckc.h: Add SAMA5
slow clock support.
* arch/arm/src/sama5/sam_pck.c and .h: Add support to use the slow
clock as the PCK clock source (2014-7-19).
* drivers/audio/wm8904.c/: The WM8904 audio driver is mostly code
complete and ready to begin initial testing (2014-7-19).
* arch/arm/src/sama5/sam_pio.c: Logic for Schmitt trigger selection
backward (2014-7-20).
* drivers/net/slip.c: Fix an error in SLIP escaping. From Max
Neklyudov (2014-7-22).
* drivers/input/Kconfg: Add missing configuration option to select the
MAX11802 touchscreen controller. From Petteri Aimonen (2014-7-22).
* arm/src/stm32/chip/stm32_dac.h: Fix typos, from Peterri Aimonen
(2014-7-22).
* arch/arm/src/stm32/stm32_otgfsdev.c: STM32 OTGFS device: Various
changes to try to reduce that amount of time in interrupts handles and
with interrupts disbled. Needs verification on other platforms. From
Petteri Aimonen (2014-7-22).
* arch/arm/src/sama5/sam_pck.c: Fix a recently introduced typo that was
being masked by some bad conditional compilation (2015=4-7-22).
* drivers/audio/wm8904.c and include/nuttx/audio/wm8904.h: Remove WM8904
driver unused parameters, clean-up comments, remove some kruft in
capability reporting (2014-7-22).
* audio/Makefile and pcm_decode.c, include/nuttx/audio/pcm_decode.c,
configs/sama5d4-ek/src/sam_wm8904.c and others: Add new framework for
the PCM decoder. It is now a 'front end' for lower-level drivers like
the WM8904 that performs the PCM decoding from end (2014-7-22).
* audio/pcm_decode.c, configs/sama5d4-ek/src/sam_wm8904.c,
drivers/audio/wm8904.c, and include/nuttx/audio/pcm.h: Rename
pcm_decode.h to pcm.h since it will hold more than just decoding
definitions. Fix some porting errors like idbg should auddbg, etc.
Add wav file header and a few low-level wav utilities (2014-7-22).
* audio/pcm_decode.c and include/nuttx/audio/pcm.h: Flesh out a few
more PCM methods, still incomplete. 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 <gnutt@nuttx.org>
* 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).

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).

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).

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 <gnutt@nuttx.org>
* 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

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).

Add logic to initialize and use ITM for syslog. Includes logic from
Pierre-noel Bouteville (2014-10-22).
* sched/sched/sched_timerexpiration.c and include/nuttx/arch.h: Fixes
to tickless operation code, especially in alarm mode. 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 shouldnt 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 didnt
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 NHDC12864KGZ 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 <gnutt@nuttx.org>
* 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).

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,

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).

CONFIG_TIVA_SSIx. 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 <gnutt@nuttx.org>
* 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 <gnutt@nuttx.org>
* 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. Ive 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).

Add support for dumping board-specific information on assertion.
From David Sidrane (2015-03-04).

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).

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).

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/<board>/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 <gnutt@nuttx.org>
* 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 S<>bastien 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. Noted
by Jouko Holopainen (2015-06-03).
* drivers/net/tun.c: TUN driver bug fix. From Max Neklyudov (2015-06-03.

(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

(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).

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).

- 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).

- Move internal DNS prototypes from dns.h to libc/netdb/lib_dns.h
- Global standard DNS definitions from libc/netdb/dns_soccket.c to

- 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).

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).

STM32F303C8, STM32F303RD, and STM32F303RE devices. 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/lpc32_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 <gnutt@nuttx.org>
* 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. See thee tools/
README file for more info (2015-10-08).
* stm32 F4: Fix some TIM12 pin mappings. 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 (2015-10-13).
* drivers/sensors/max6675.c and include/nuttx/sensors/max6675.h: Add
support to Thermocouple-to-Digital converter MAX6675. 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. From Wail Khemir
(2015-11-17).
* drivers/sensors/ms58xx.c: Fix some issues with initialization and with
CRC calculation. From Karim Keddam (2015-11-17).
* drivers/mtd/w25.c: Fix W25 FLASH driver page read/write logic. From
Ken Pettit (2015-11-18).
* drivers/mtd/smart.c: Fix a Smart wear-leveling bug. From Ken Pettit
(2015-11-18).
* arch/sim/src/up_spiflash.c: Add support for W25 FLASH simulation.
From Ken Pettit (2015-11-18).
* configs/boardctl.h, Kconfig, include/sys/boardctl.h, and nuttx/board.h:
Add a command to the boardctl() interface to obtain a board unique ID
(2015-11-18).
* drivers/timers/ds3231.c: Driver extended to include support for the
DS1307 RTC (2015-11-18).
* configs/same70-xplained: Add basic NSH configuration for the SAME70
Xplained board. Initial commit is just the SAMV71-XULT files with
names changed appropriately (2015-11-18).
* drivers/mtd/smart.c: Fixed SmartFS wear level error that occurs when
the logical sector size is too small to save all wear level status
bytes in a single sector. 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 <gnutt@nuttx.org>
* 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 St<53>hn
(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

dependencies generated by a Windows compiler so that they can be
used with the Cygwin make (2016-01-09).
* tools/mkwindeps.sh: A script that coordinates use of cnvwindeps.exe
(2016-01-09).
* tools/mkdeps.c: Deleted mkdeps.sh and mkdeps.bat. 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).

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).

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).

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).

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).

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).

* 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).

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 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 <gnutt@nuttx.org>
* 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. Not yet
used by NuttX (2016-02-09).
* include/nuttx/arch.h, sched/sched/sched.h: Add some basic definitions
that may be needed for SMP support (2016-02-10).
* sched/init/os_start.c, sched/init/os_smpstart.c, and include/nuttx/arch.h:
Add some tentative SMP start-up logic (2016-02-10).
* arch/arm/sim/up_head.c and up_simsmp.c: Add multi-CPU support to the
simulation to support SMP investigation.. 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. Implements pthread_att_setaffinity_np()
and pthread_attr_getaffinity_np() (2016-02-19).
* sched/pthread: Add pthread_setaffinity() and pthread_getaffinity()
(2016-02-19).
* sched/sched: Add sched_setaffinity() and sched_getaffinity() (2016-02-19).
* drivers/leds/rgbled.c: Add a driver to manage a RGB LED via PWM. From
Alan Carvalho de Assis (2016-02-22).
* arch/arm/src/stm32f4discovery: Add PWM support for the onboard RGB LED
From Alan Carvalho de Assis (2016-02-22).
* arch/arm/src/samv7: HSMCI driver can now be configured to handle unaligned
data buffers (2016-02-22).
* fs/fat: Add an option to force all transfers to be performed indirectly
using the FAT file system's internal sector buffers (2016-02-22).
* drivers/wireless/ieee802154: New directory. Nothing there yet (2016-02-25).
* wireless/: New top level directory. Nothing there yet (2015-02-26).
* wireless/ieee802154: Add an new directory to the build. Nothing there
yet (2016-02-26).
* include/nuttx/wireless/ieee802154: Add directory (and dummy header file)
(2016-02-16).
* arch/arm/include and src: Rename the imx directories to imx1 to make room
in the namespace for other members of the i.MX family (2016-02-27).
* arch/arm/include/imx6 and src/imx6: Evolving support for the NXP/Freescale
i.MX6Q (2016-02-28).
* configs/sabre-6quad: Placeholder that will eventually become board support
for the NXP/Freescale Sabre 6Quad board (2016-02-28).
* arch/arm/src/stm32: Support for STM32F46xx from Paul Alexander Patience
* sched/semaphore/sem_reset.c and include/nuttx/semaphore.h: Add an internal,
non-standard interface to reset a semaphore count. 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 <gnutt@nuttx.org>
* 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).

CPUn, n > 0, when CONFIG_SMP=y (2016-05-13).
* arch/arm/src/imx6 and configs/sabre-6quad: The basic i.MX6 port is

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).

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).

* 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).

7.17 2016-xx-xx Gregory Nutt <gnutt@nuttx.org>
* 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).

(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

(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).

* 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.

* 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).
* arch/arm/src/stm32: Port STM32L4 CAN IOCTLs to STM32. From Sebastien
Lorquet (2016-06-24).
* configs/Konfig:Add configuration logic to include a Kconfig file in
each custom configuration. Includes adding a dummy custom board
configuration directory. A consequence of this that each custom board
directory will now need to contain a Kconfig file. NOTE also that
the new board directory does not take effect in the configuration
menus until the NEXT time you run 'make menuconfig' (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)
