-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 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 <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).
-
-0.2.7 2007-06-09 Gregory Nutt <spudmonkey@racsa.co.cr>

- * 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 <spudmonkey@racsa.co.cr>
- * 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

- 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.

- 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.
-

-
- * Separated net/uip/uip.c into several functions in several files.
- * Corrected a TCP problem where packets were dropped because there was no

-- Several APIs do not set errno. Need to review all APIs.
-
-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

+ (3) pjrc-8052 / MCS51 (arch/pjrc-8051/)
+
+
+o Task/Scheduler (sched/)
+ ^^^^^^^^^^^^^^^^^^^^^^^
+
+ Description: When a tasks exits, shouldn't all of its child pthreads also be
+ 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
-- Need to call static constructors
-
-o Network
-- uIP's netutils/smtp, resolv, webclient -- untested
-- Should implement SOCK_RAW, SOCK_PACKET
-- uIP polling issues:
- (1) Current logic will not support multiple ethernet drivers. 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.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
-- Implement USB device support
-- Implement USB bulk device
-
-o Libraries
-- sscanf() and lib_vsprintf() do not support floating point values.
-- 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.
-
-o File system
-- Add chmod(), truncate().
-- FAT32: long file names
-
-o Documentation
-- Document driver/ logic
-- Document C-library APIs
+ ^^^^^^^^^^^
+
+ Description: Need to call static constructors
+ Status: Open
+ Priority: Low, depends on toolchain. Call to gcc's built-in static
+ constructor logic will probably have to be performed by
+ user logic in user_start().
+
+o Network (net/, netutils/)
+ ^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ Description: Several of the netutils/ apps are untested. These include
+ uIP's netutils/smtp, dhcpd, resolv, webclient. Only minimal
+ testing of the others has been performed.
+ Status: Open
+ Priority: Medium, Important but not core NuttX functionality
+
+ Description: Should implement SOCK_RAW, SOCK_PACKET
+ Status: Open
+ Priority: Low
+
+ Description: uIP polling issues / Multiple network interface support:
+ (1) Current logic will not support multiple ethernet drivers.
+ 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
+ Priority: High
+
+o Libraries (lib/)
+ ^^^^^^^^^^^^^^^^
+
+ Description: sscanf() and lib_vsprintf() do not support floating point
+ values.
+ Status: Open
+ Priority: Low
+
+ 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.
+ Status: Open
+ Priority: Mediam
+
+o File system (fs/, drivers/)
+ ^^^^^^^^^^^^^^^^^^^^^^^^^^^

+ Description: Add chmod(), truncate().
+ Status: Open
+ Priority: Low
+
+ Description: FAT32: long file names
+ Status: Open
+ Priority: Medium
+
+o Documentation (Documentation/)

o Build system
-- Some names under arch are still incorrect. These should be processor architecture
- names: pjrc-8051 should be 805x
-- configs/pjrc-8051 should be configs/pjrc-87c52
-- Dependencies do not work correctly under configs/<board>/src (same as arch/<arch>/src/board).
-
-o Applications & Tests
-
-o ARM
-- Add option to use a separate stack for interrupt handling. At present,
- each interrupt executes on top of the user stack allocation making each
- user stack allocation larger than needed.
-
-o ARM/C5471
-
-o ARM/DM320
-- It seems that when a lot of debug statements are added, the system no
- longer boots. This has been diagnosed as a stack problem.. making the stack
- bigger or removing arrays on the stack fixes the problem.
-
-o ARM/LPC214x
-- Finish bringup
-- Add MMC and USB support
-
-o pjrc-8052 / MCS51
-- Current status:
- - Basic OS task management seems OK
- - Fails when interrupts enabled. The stack pointer is around 0x6e
- before the failure occurs. It looks like some issue when the
- stack pointer moves from the directly to indirectly addressable
- region (0x80 boundary).
- - Work on the 8052 is temporarily on hold
-- Use timer 0 as system timer. Timer 2 is needed for second UART.
- Logic is implemented, but there needs to be a system configuration
- to change the ticks-per-second value to match the timer interrupt
- rate
-- During build, there are several integer overflows reported:
- gmtime_r.c aroud lines 184 and 185
- clock_initialize.c at line 107
- pthread_create.c at 330
- sighand.c at 225 and 244

+o ARM (arch/arm/)
+ ^^^^^^^^^^^^^^^

+ Description: Add option to use a separate stack for interrupt handling. At
+ present, each interrupt executes on top of the user stack
+ allocation making each user stack allocation larger than needed.

+ ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+ Description: config/ntos-dm320: It seems that when a lot of debug statements
+ are added, the system no longer boots. This is suspected to be
+ a stack problem: Making the stack bigger or removing arrays on
+ the stack seems to fix the problem (might also be the
+ bootloader overwriting memory)
