0.1.0 2007-03-09 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* Initial Release
* Support for Linux user mode simulation and TI
TMS320C5471 (Arm7) provided
0.1.1 2007-03-14 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 &lt;spudmonkey@racsa.co.cr&gt;
* 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 support for block devices.
* Simulated target now exports a VFAT filesystem
* Begin support for VFAT filesystem (missing functionalit)
* Added mount() and umount()
* Fix bug in memcmp return value
* Fix errors in timeslice calculation (several places)
* Added missing irqrestore() in timer_deletall().
* close() was not closing the underlying device.
* Added fsync()
* Added strspn() and strcspn()
0.2.6 2007-05-26 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* 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).
0.2.7 2007-06-09 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* Added stat() to fs layer and to FAT
* Fixed reference counting errors associated with mounted filesystems
* Added fat_getattrib() and fat_setattrib()
* Added statfs() to fs layer and to FAT
* Correct file name extension in tools/zipme.sh
* Fix error in dependencies in 8051/2 Makefile
* sched/Makefile: Don't build sleep() or usleep() if signals are disabled
* sched/sched_setparam.c: Remove redundant disabling of interrupts
* sched/usleep.c: Fixed nsec calculation
* lib/lib_strcspn.c: Function incorrectly named strspn().
* examples/ostest/main.c: Errors in SDCC version of a memcpy() call
* examples/ostest/sighand.c: Don't call fflush() if streams are disabled
* include/limits.h, include/time.h, sched/clock_internal.h: A support for
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.
* include/assert.h & arch/pjrc-8051/src/up_assert.c: SDCC does support
__FILE__and __LINE__ (not tested)
* examples/ostest/barrier.c: Don't call usleep() when signals are
disabled.
0.2.8 2007-07-02 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* tools/Makefile.mkconfig: Under Cygwin, executable has a different name
* tools/mkdeps.sh & arch/arm/src/Makefile: Corrected a problem makeing dependencies
* tools/zipme.sh: Force directory name to be nuttx-xx.yy.zz
* fs/fs_opendir.c: Correct errors in semaphore usage that can cause deadlock.
* lib/lib_getopt.c: Added getopt() support

-l -s, and -R
* Added basic OS support to manage environment variables: environment
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.
* lib/: Added strrchr, basename, dirname
* examples/nsh/: Add cp, rm, rmdir, set, unset commands. echo will now print
environment variables.
0.3.0 2007-11-06 Gregory Nutt &lt;spudmonkey@racsa.co.cr&gt;
* Imported uIP into the tree (see

* Separated net/uip/uip.c into several functions in several files.
* Corrected a TCP problem where packets were dropped because there was no
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.
* Basic server functionality verified: listen(), accept()
* Fix DM90x0 driver problem that caused TX overruns
* Add strncmp()
* Added TCP/IP read-ahead buffer to minimize failed ACKs and packet loss.

NuttX TODO List NuttX TODO List (Last updated December 13, 2007)
^^^^^^^^^^^^^^^ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
o Task/Scheduler (6) Task/Scheduler (sched/)
- When a tasks exits, shouldn't all of its child pthreads also be terminated? (2) Memory Managment (mm/)
- Should task_delete() cause atexit() function to be called? (1) Signals (sched/, arch/)
- Implement sys/mman.h and functions (1) pthreads (sched/)
- Implement sys/wait.h and functions (1) C++ Support
- Implement priority inheritance (10) Network (net/, netutils/)
- Consider implementing wait, waitpid, waitid. At present, a parent has (2) USB (drivers/usbdev)
no information about child tasks. (2) Libraries (lib/)
- Several APIs do not set errno. Need to review all APIs. (2) File system (fs/, drivers/)
(2) Documentation (Documentation/)
(3) Build system
(0) Applications & Tests (examples/)
(1) ARM (arch/arm/)
(0) ARM/C5471 (arch/arm/src/c5471/)
(1) ARM/DM320 (arch/arm/src/dm320/)
(2) ARM/LPC214x (arch/arm/src/lpc214x/)
(3) pjrc-8052 / MCS51 (arch/pjrc-8051/)
o Memory Managment
- Add an option to free all memory allocated by a task when the task exits.
This is probably not be worth the overhead for a deeply embedded system.
- Current logic adapts size_t for 16-bit address machines vs. 32-bit address
machines. But a small memory option should also be provided so that
the small offset option can be used with 32-bit machines that have small
RAM memories (like the lpc2148)
o Signals o Task/Scheduler (sched/)
- 'Standard' signals and signal actions are not supported. ^^^^^^^^^^^^^^^^^^^^^^^
o pthreads Description: When a tasks exits, shouldn't all of its child pthreads also be
- pthread_cancel(): Should implement cancellation points and pthread_testcancel() terminated?
Status: Open
Priority: Medium, required for good emulation of process/pthread model.
Description: atexit() supports registration of one function called on exit().
Should task_delete() also cause atexit() function to be called?
Status: Open
Priority: Low, task_delete() is non-standard and its behavior is
unspecified.
Description: Implement sys/mman.h and functions
Status: Open
Priority: Low
Description: Implement sys/wait.h and functions. Consider implementing wait,
waitpid, waitid. At present, a parent has no information about
child tasks.
Status: Open
Priority: Low
Description: Implement priority inheritance
Status: Open
Priority: Medium, this is a good feature for realtime systems.
Description: Several APIs do not set errno. Need to review all APIs.
Status: Open
Priority: Medium, required for standard compliance (but makes the
code bigger)
o Memory Managment (mm/)
^^^^^^^^^^^^^^^^^^^^^^
Description: Add an option to free all memory allocated by a task when the
task exits. This is probably not be worth the overhead for a
deeply embedded system.
Status: Open
Priority: Medium/Low, a good feature to prevent memory leaks but would
have negative impact on memory usage and code size.
Description: Current logic adapts size_t for 16-bit address machines vs.
32-bit address machines. But a small memory option should also
be provided so that the small offset option can be used with
32-bit machines that have small RAM memories (like the lpc2148)
Status: Open
Priority: High, a good feature enhancement.
o Signals (sched/, arch/)
^^^^^^^^^^^^^^^^^^^^^^^
Description: 'Standard' signals and signal actions are not supported.
(e.g., SIGINT, SIGCHLD, SIGSEGV, etc).
Status: Open
Priority: Low, required by standards but not so critical for an
embedded system.
o pthreads (sched/)
^^^^^^^^^^^^^^^^^
Description: pthread_cancel(): Should implement cancellation points and
pthread_testcancel()
Status: Open
Priority: Low, probably not that useful
o C++ Support o C++ Support
- Need to call static constructors ^^^^^^^^^^^
o Network Description: Need to call static constructors
- uIP's netutils/smtp, resolv, webclient -- untested Status: Open
- Should implement SOCK_RAW, SOCK_PACKET Priority: Low, depends on toolchain. Call to gcc's built-in static
- uIP polling issues: constructor logic will probably have to be performed by
(1) Current logic will not support multiple ethernet drivers. Each driver should user logic in user_start().
poll on TCP connections connect on the network supported by the driver; UDP
polling should respond with TX data only if the UDP packet is intended for the
the network supported by the driver.
(2) If there were multiple drivers, polling would occur at double the rate.i
Fix by using bound IP address in TCP connection (lipaddr) and verifying that it
is in the subnet served by the driver.
- uIP/Socket callback logic is not thread safe. This means that a socket cannot be
used concurrently by two threads. Minimal fix: Add mutex to support exclusion.
- IPv6 support is incomplete
- Incoming UDP broadcast should only be accepted if listening on INADDR_ANY(?)
- Should add some driver call to support throttling... when there is no listener
for new data, the driver should be throttled. Perhaps the driver should disable
RX interrupts when throttled and re-anable on each poll time. recvfrom would,
of course, have to un-throttle.
- Need to standardize collection of statistics from network drivers. examples/nsh
ifconfig command should present statistics.
o USB o Network (net/, netutils/)
- Implement USB device support ^^^^^^^^^^^^^^^^^^^^^^^^^
- Implement USB bulk device
o Libraries Description: Several of the netutils/ apps are untested. These include
- sscanf() and lib_vsprintf() do not support floating point values. uIP's netutils/smtp, dhcpd, resolv, webclient. Only minimal
- The definition of environ in stdlib.h is bogus and will not work as it should. This testing of the others has been performed.
is because the underlying representation of the environment is not an arry of pointers. Status: Open
Priority: Medium, Important but not core NuttX functionality
o File system Description: Should implement SOCK_RAW, SOCK_PACKET
- Add chmod(), truncate(). Status: Open
- FAT32: long file names Priority: Low
o Documentation Description: uIP polling issues / Multiple network interface support:
- Document driver/ logic (1) Current logic will not support multiple ethernet drivers.
- Document C-library APIs Each driver should poll on TCP connections connect on the
network supported by the driver; UDP polling should respond
with TX data only if the UDP packet is intended for the
the network supported by the driver.
(2) If there were multiple drivers, polling would occur at
double the rate. Fix by using bound IP address in TCP
connection (lipaddr) and verifying that it is in the subnet
served by the driver.
Status: Open
Priority: Medium, The feature is not important, but it is important
for NuttX to resolve the architectural issues.
Description: Sendoto() and multiple network interface support:
When polled, would have to assure that the destination IP
is on the subnet served by the polling driver.
Status: Open
Priority: Medium, The feature is not important, but it is important
for NuttX to resolve the architectural issues.
Description: uIP/Socket callback logic is not thread safe. This means that
a socket cannot be used concurrently by two threads. Minimal
fix: Add mutex to support exclusion for protection.
Status: Open
Priority: Low. The currently socket design cannot be use concurrently
by threads with out a major redesign. The feature is not
of great value since the use model for multi-thread sockets
is not common. Adding mutex support would only mask the
underlying issue.
Description: IPv6 support is incomplete
Status: Open
Priority: Medium
Description: Incoming UDP broadcast should only be accepted if listening on
INADDR_ANY(?)
Status: Open
Priority: Low
Description: Read-ahead buffers capture incoming TCP data when no user
thread is recv-ing the data. Should add some driver call to
support throttling; when there is no listener for new data, the
driver should be throttled. Perhaps the driver should disable
RX interrupts when throttled and re-anable on each poll time.
recvfrom would, of course, have to un-throttle.
Status: Open
Priority: Medium
Description: Need to standardize collection of statistics from network
drivers. examples/nsh ifconfig command should present
statistics.
Status: Open
Priority: Low
Description: Outgoing packets are dropped and overwritten by ARP packets
if the destination IP has not been mapped to a MAC. Could
improve send() performance by explicitly performing ARP before
sending the packet.
Status: Open
Priority: Medium
o USB (drivers/usbdev)
^^^^^^^^^^^^^^^^^^^^
Description: Implement USB device support
Status: Open
Priority: High
Description: Implement USB bulk / serial device support
Status: Open

o Libraries (lib/)
^^^^^^^^^^^^^^^^
Description: sscanf() and lib_vsprintf() do not support floating point
values.
Status: Open

Description: The definition of environ in stdlib.h is bogus and will not
work as it should. This is because the underlying
representation of the environment is not an arry of pointers.
