Raw Blame History

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 sempahores (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.

* 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).

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)

* NSH: $variable can be used for any command value
* Fixed an error in opendir() that could cause an assertion to fail
inappropriately.
* Correct an error in the FAT that caused files opened for writing with
O_APPEND to fail. The file was not being properly positioned to the
end of the file in that case.
* NSH now supports last exit status $?

* 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

any remote UDP port.
* NSH: Add hexadecimal dump command (xd)
* Fixed several critical bugs with regard to fat reading and writing and FAT12
accesses. Basically the FAT FS only worked with my tiny test files and test
cases. A lot of stronger FAT tested is needed!!
* Fixed another FAT bug in implementation of FAT lseek; this prohibit correct
random access to large files.
0.3.15 2008-09-20 Gregory Nutt <gnutt@nuttx.org>

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.

* ARM architectures now support drivers/lowconsole.c
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 intialization 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: Corrrect 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.
* confgs/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.
* configs/ea3131/src/up_ubstrgc.c, configs/ea3131/usbserial,

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

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
desciption). 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: http://tech.groups.yahoo.com/group/nuttx/message/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.
* confgs/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 desciptor 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/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 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.
* confgs/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/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/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.
* arch/mips/src/pic32mx/pic32mx_usbdev.c: Add a USB device-side driver
for the PIC32MX family.
* arch/arm/src/stm32/stm32_gpio.c: Correct an error in some of the GPIO
initialization logic. Fix submitted by Mike Smith.
* configs/olimex-lpc1766stk/src/up_leds.c: Add new interfaces so that is
CONFIG_ARCH_LEDS are not set, the LEDs may be controlled from application
logic.
* configs/olimex-lpc1766stk/src/up_buttons.c: Add support for the buttons
on the Olimex LPC1766-STK board.
* Makefile: Added 'apps_clean' and 'apps_distclean' target to simplify
managing the state of the application directory while in the NuttX directory
* Documentation/NuttXGettingStarted.html: Added a "Getting Started" Guide
for NuttX. At present, this is just a stub and it refers to the NuttX
top-level README.txt file which is the only, real "Getting Started" Guide
that exists at the time being.
* arch/arm/src/lpc17xx/lpc17_gpioint.c: Correct an value used as the lower
end of an IRQ number range test.
* arch/arm/src/lpc17xx/lpc17_gpio.c: Fix a integer flow problem in shift.
This error would prevent pins > 15 from being used as interrupt sources.
* arch/arm/src/stm32/stm32_can.c: The CAN driver has been verified in
loopback mode on the STM3240G-EVAL board.
* configs/stm3240g-eval/src/up_adc.c: Complete coding of ADC support for the
potentiometer on board the STM3240G-EVAL.
* arch/arm/src/lpc17_can.c: Several CAN driver improvements. Adds support for
testing in loopback mode. now uses all three transmit buffers for better
performance.
* confgs/olimex-lpc1766stk/nsh: Now supports the CAN loopback test as an
optional "built-in" application.
* sched/irq_attach.c: Fix an issue with disabling interrupts when they are
detached. For the PIC32, this can't be done because there is a 1-to-many
relationship between vector numbers and interrupt numbers or different.
Added a new configuration option CONFIG_ARCH_VECNOTIRQ to at least flag
the architectures that have this issue and to (at least) avoid doing
something too wrong.
* drivers/can.c: Fix a test for buffer full in the generic, "upper half",
can driver.
* arch/arm/src/lm3s: Add support for the LM3S6432S2E (Contributed by Mike Smith)
* configs/lm3s6432-s2: Add support for the TI RDK-S2E (LM3S6432S2E) board
(Contributed by Mike Smith)
* configs/stm3240g-eval/src: Add APIs support to support user access to the
LEDs

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.
* confgs/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_internal.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.
* confgs/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.
* confgs/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 whent he 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 (2103-3-26).
* 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 (2103-3-27).
* 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 interrrupts 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 whent the PLL output is
400MHz. Don't forget to set the USERCC2 bit in the register or
all is for naught (2013-4-09).
* configs/zkit-arm-1769/src/up_lcd.c, up_ssp.c, and up_spi.c:
Use SSP0 to LCD and SPI to SD-Card on the Zkit-arm-1769 board.
From Manikandan. S (2013-4-10)
* configs/olimex-lpc1766stk/usbserial: Converted to use the
kconfig-config frontends tools (2013-4-12).
* drivers/usbdev/pl2303.c: Fix some compilation errors that
crept in when fixes to the CDC/ACM driver where blindly
incorporated in the PL2303 driver (2013-4-12).
* configs/stm3210e-eval/usbserial: Converted to use the
kconfig-config frontends tools (2013-4-12).
* configs/nucleus2g/usbserial: Converted to use the
kconfig-config frontends tools (2013-4-12).
* arch/arm/src/kl and arch/arm/include/kl: Add support for the
Kinetis L family of Cortex-M0+ MCUs. Contributed by Alan
Carvalho de Assis. NOTE: This is still very much a work in
progress as of this initial commit (2013-04-16).
* configs/freedom-kl25z: Support for the Freedom KL25Z board
contributed by Alan Carvalho de Assis. NOTE: This is still
very much a work inprogress as of this initial commit
(2013-04-16).
* arm/arm/src/armv6-m and arch/arm/include/armv6-m: Ooops. Fix
a major screw-up: The Cortex-M0 has no BASEPRI register but
the current logic was using it to manage interrupts. Switch
to using the PRIMASK. This means that hardfaults will (again)
occur when SVC instructions are executed (2013-4-16).
* configs/stm3240g-eval/ostest: Converted to use the kconfig-frontends
tools (2013-4-17).
* sched/task_exithook.c: Don't flush the streams until the
final thread of the group exits. Flushing may cause the
thread to get suspended at a bad time and other threads in the
group may run while the exiting thread is in an unhealthy state.
This can cause crashes under certain circumstance. This is a
critical bugfix (2013-4-18).
* drivers/mtd/ramtron.c: Extended to support the FM25V01 device.
Contributed by Lorenz Meier (2013-4-18).
* sched/task_deletecurrent.c and task_exit.c, arch/*/up_exit.c:
Renamed task_deletecurrent() and task_exit() since it really
handles the architecture independent part of _exit(). _exit()
is used internally, but if it is called from the user, it should
unregister any atexit() or on_exit() functions (2013-4-18).
* tools/kconfig2html.c: This is the beginning of a tool to
replace the hand-generated documentation of the NuttX configuration
variables with auto-generated documentation. The initial checkin
is an incomplete, poorly structured prototype that I hope to
evolve into a useful tool (2014-4-20).
* libc/string/lib_strchr.c: strchr(str, '\0') should return a
pointer to the end of the string, not NULL. From Petteri
Aimonen (2014-4-22).
* fs/fat/fs_writefat.c: mkfatfs was writing the boot code to the
wrong location. From Petteri Aimonen (2014-4-22).
* Documentation: The NuttX documentation now expects to find an
auto-generated version of the configuration variable documentation
at Documentation/NuttXConfigVariables.html (2014-4-22).
* arch/arm/src/lpc17xx/lpc17_adc.c: Only one ADC pin was configured.
Need to configure all that are in the ADC0 set. From MKannan
(2014-4-23).
* configs/zkit-arm-1769/src: ADC and SPI/USB MSC updates from
MKannan (2014-4-23).
* arm/src/armv7-m/ram_vectors.h and arm/src/armv7-m/up_ramvec_initialize.c:
Fixes to RAM vector logic from Paul Y. Zhang (2014-4-23)
* tools/kconfig2html.c: Improve behavior of Expand/Collapse
Table of Contents; Handle errors in parsing of strings and in
some uninitialized variables. Add an option to use jQuery.
* tools/mkconfigvar.sh: Fix make target (2014-4-23).
* sched/exit.c, pthread_exit.c, task_exit.c, task_delete,c and
task_exithook.c: For pthread_exit(), move some logic to an early
point in the exit sequence where the task may need to block. Add
conditional logic in the lower end of the eixt logic kicked off by
_exit() to prohibit blocking after the task has been torn down and is
no longer cabable of blocking (2014-4-23).
* arch/arm/src/common/up_initialize.c: Add missing registration
of /dev/zero. Registration of /dev/null should depend upon
conditional compilation. From Ken Pettit (2014-4-24).
* arch/*/src/common/up_initialize.c: Same change required to other
architectures (2014-4-24).
* arch/arm/src/kl/kl_clockconfig.c and configs/freedom-kl25z/include/board.h:

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 intialization function (2013-4-30).

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

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).

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).

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).

to include a few differences for the SAM4L (2013-6-19)
* arm/src/sam34/chip/sam4l_pdca.h: Add SAM4L PDCA register definition
file; also renamed sam_dmac.* files to sam3u_dmac.* to identify
them as SAM4U/4S only files (2013-6-19).
* configs/freedom-lk25z/src/kl_spi.c: Add the framework for
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).

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)

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 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 enpoints 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).

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).

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
defintion 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-xx-xx 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).

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 (2018-8-2).
* 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

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).
* confgis/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).

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 tranfer 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 necessasrybecause 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 Holtberg
(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).
