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 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>
* Verfied 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 effects 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

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 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 fot 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
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 bin 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 suppor 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 verifed 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 ar now cloned when 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 occurrents 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-drivent,
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 a 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 contant 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,
configs/ea3131/usbstorage - USB storage and USB serial example support
contributed by David Hewson.
* Several important compilation error fixes in lpc313x and (dualspeed) USB
code also contributed by David Hewson.
* arch/arm/src/sam3u/sam3u_dmac.c - DMA support for the AT90SAM3U.
* arch/arm/src/sam3u/sam3u_hsmci.c - SD memory card support for AT90SAM3U
(Neither the DMA nor the HSMCI driver are functional on the initial checkin).
* drivers/usbdev - Several important fixes to the USB mass storage driver
submitted by David Hewson.
* configs/olimex-lpc2378, arch/arm/include/lpc2378, and arch/arm/src/lpc2378 -
Basic port of the NXP 2378 on the Olimex board contributed by
Rommel Marcelo.
* arch/arm/src/sam3u/sam3u_internal.h - Fixed a critical bug in the AT91SAM3U
PIO decoding. No PIOs greater than 15 could be used on any port! Obviously,
no one has been using this port.
5.4 2010-04-23 Gregory Nutt <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
