Raw Blame History

0.1.0 2007-03-09 Gregory Nutt <spudmonkey@racsa.co.cr>
* Initial Release
* Support for Linux user mode simulation and TI
TMS320C5471 (Arm7) provided
0.1.1 2007-03-14 Gregory Nutt <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* Verified c5471 build under Cygwin on WinXP
* Makesystem changes to better support different SoCs.
* Made arch/c5471/include and arch/dm320/include identical in
preparation for merging into arch/arm
* Logic from arch/c5471 and arch/dm320 combined into arch/arm.
arch/c5471 and arch/dm320 are deprecated and will be removed
when the new c5471 and dm320 logic is verified.

0.2.6 2007-05-26 Gregory Nutt <spudmonkey@racsa.co.cr>
* Added unlink(), mkdir(), rmdir(), and rename()
* Fixed several serious FAT errors with oflags handling (&& instead of &)
* Added FAT support for unlink(), mkdir(), rmdir(), and rename
* Added FAT support for opendir(), closedir(), readdir(), seekdir(),
telldir(), rewindir().
* Fixed ARM compilation errors introduced in 0.2.5 (that is what I get
for only testing on the simulation).

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.

* 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 <spudmonkey@racsa.co.cr>
* 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!!

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

0.3.16 2008-10-10 Gregory Nutt <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 (16Kb 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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,

contributed by David Hewson.
* Several important compilation error fixes in lpc313x and (dualspeed) USB
code also contributed by David Hewson.
* arch/arm/src/sam3u/sam3u_dmac.c: DMA support for the AT90SAM3U.
* arch/arm/src/sam3u/sam3u_hsmci.c: SD memory card support for AT90SAM3U
(Neither the DMA nor the HSMCI driver are functional on the initial checkin).
* drivers/usbdev: Several important fixes to the USB mass storage driver
submitted by David Hewson.
* configs/olimex-lpc2378, arch/arm/include/lpc2378, and arch/arm/src/lpc2378 -
Basic port of the NXP 2378 on the Olimex board contributed by
Rommel Marcelo.
* arch/arm/src/sam3u/sam3u_internal.h: Fixed a critical bug in the AT91SAM3U
PIO decoding. No PIOs greater than 15 could be used on any port! Obviously,
no one has been using this port.
5.4 2010-04-23 Gregory Nutt <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* configs/nucleus2g: Add ostest configuration for the Nucleus 2G
LPC1768 board from 2G Engineering (http://www.2g-eng.com/)
* arch/arm/src/lpc17xx: Added basic LPC17xx boot-up logic,
interrupt handling, and GPIO configuration.
* configs/nucleus2g/ostest: Completed bring-up of LPC1768 on
the Nucleus2G board using the examples/ostest
* configs/nucleus2g/nsh: Added and verified a NuttShell (NSH)
configuration for the LPC1768 on the Nucleus2G board.
5.8 2010-07-18 Gregory Nutt <spudmonkey@racsa.co.cr>
* 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/lp17_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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 (16Kb). 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 8Kb at the beginning of Bank0; the 8Kb 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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.
* examplex/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://nuttx.svn.sourceforge.net/viewvc/nuttx/
* 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 <spudmonkey@racsa.co.cr>
* 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/lp17_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/uart_16550.c and include/nuttx/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_ATEXT 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 <spudmonkey@racsa.co.cr>
* 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 <spudmonkey@racsa.co.cr>
* 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 kernal 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-xx-xx Gregory Nutt <spudmonkey@racsa.co.cr>
* 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_uptime() and lib/time/lib_time.c: Add support for 1 second uptime
interface.
