-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.
-
-0.2.5 2007-05-19 Gregory Nutt <spudmonkey@racsa.co.cr>

- * Corrected some build/configuration issues introduced with the
- last release.
- * Added support for the NXP 214x processor on the mcu123.com lpc214x
- development board (untested)

- * Added mount() and umount()
- * Fix bug in memcmp return value
- * Fix errors in timeslice calculation (several places)

-
-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.

- * examples/nsh/: Break into several files.
- * lib/: Added strrchr, basename, dirname

-
- * Separated net/uip/uip.c into several functions in several files.
