The goal is to provide most standard POSIX OS interfaces to support
|
|
a rich, multi-threaded development environment for deeply embedded
|
|
processors.
|
|
</p>
|
|
NON-GOALS: (1) It is not a goal to provide the rich level of OS
|
|
features like those provided with Linux.
|
|
Small footprint is more important than features.
|
|
Standard compliance is more important than small footprint.
|
|
(2) There is no MMU-based support for processes.
|
|
At present, NuttX assumes a flat address space.

weak symbols when available.

NuttX strives to achieve a high degree of standards compliance.
|
|
The primary governing standards are POSIX and ANSI standards.
|
|
Additional standard APIs from Unix and other common RTOS's are
|
|
adopted for functionality not available under these standards
|
|
or for functionaly that is not appropriate for the deeply-embedded
|
|
RTOS (such as <code>fork()</code>).
|
|
</p>
|
|
<p>
|
|
Because of this standards conformance, software developed under other
|
|
standard OSs (such as Linux) should port easily to NuttX.

The 13th release of NuttX (nuttx-0.3.0) is available for download
|
|
from the <a href="http://sourceforge.net/project/showfiles.php?group_id=189573">SourceForge</a>
|
|
website.
|
|
The change log associated with the release is available <a href="#currentrelease">here</a>.
|
|
Unreleased changes after this release are avalable in CVS.
|
|
These unreleased changes are listed <a href="#pendingchanges">here</a>.
|
|
</p>
|
|
<p>
|
|
NuttX 0.3.1 is the second release containing the integration of a network
|
|
subsystem and the uIP TCP/IP, UDP, and ICMP stacks based on
|
|
<a href="http://www.sics.se/~adam/uip/index.php/Main_Page">uIP</a>
|
|
into NuttX.
|
|
</p>
|
|
<p>
|
|
Many network-related problems have been fixed from version 0.3.0
|
|
and the implementation has matured significantly.
|
|
However, the level of network reliability is probably still at the
|
|
pre-alpha or early level.
|
|
It is sufficiently complete that you may begin to perform some network
|
|
integration and is exepcted to achieve beta level of reliability over
|
|
the next few releases.
|
|
</p>
|
|
<p>
|
|
The baseline functionality of NuttX continues to mature and remains at
|
|
post-beta (as long as the network is not used).

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.

|
|
|
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>

|
* 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>

|
|
* 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).
|
|
|
|

|
|
using selectable system timer frequency.
|
|
* Fixed error in mountpoint related conditional compilation introduced
|
|
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.
|
|

storage, cloning on task creation, sharing on pthread creation, destruction
|
|
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.

0.3.1 2007-11-19 Gregory Nutt <spudmonkey@racsa.co.cr>
|
|
|
|
* Separated net/uip/uip.c into several functions in several files.
|
|
* Corrected a TCP problem where packets were dropped because there was no

|
* Basic server functionality verified: listen(), accept()
|
|
* Fix DM90x0 driver problem that caused TX overruns
|
|
