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
* 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
* 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
* Add dirent.h, opendir(), readdir(), closedir(), etc.
* 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.
* Separated C5471 serial driver; a shareable part is
in drivers/. ; the C5471 specific part is in arch/C5471.
serial.h defines the interface.
* 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
* Major restructuring of header files to get closer to
POSIX compliance.
* Eliminate compilation warnings that that crept into
recent check-ins
* 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
* 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
* 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.
0.2.5 2007-05-19 Gregory Nutt <spudmonkey@racsa.co.cr>

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

on thread/task exit.
* Add environment variables APIs: environ, getenv, putenv, clearenv, setenv,
unsetenv
* Correct an error in realloc() when the block is extended "down" in memory.
In this case, the old memory contents need to be copied to the new location
and an allocated bit was not being set.
* examples/ostest/: Added an environment variable test.
* examples/nsh/: Break into several files.
* lib/: Added strrchr, basename, dirname

recv() in place but the packet was being ACKed. There are still TCP
recv buffering issues, but this is part of a larger buffering issue.
