This 44<sup>th</sup> release of NuttX was made on October 17, 2009 and 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 available in CVS.
|
||||
These unreleased changes are listed <a href="#pendingchanges">here</a>.
|
||||
This release of NuttX incorporates the verified port of Jeff Poskanzer's <a href="http://acme.com/software/thttpd">THTTPD</a> HTTP server.
|
||||
Many of the key features of THTTPD have been tested on the Micromint Eagle-100 development board (Cortex-M3).
|
||||
These tests verify:
|
||||
</p>
|
||||
<ul>
|
||||
<li>Serving of files from any file system, and </li>
|
||||
<li>Execution of CGI executable.
|
||||
This release supports execution of <a href="http://www.nuttx.org/NuttXNxFlat.html">NXFLAT executables</a> residing on a ROMFS file system.
|
||||
</ul>
|
||||
<p>
|
||||
A standard CGI interface is used: Information is pasted to the CGI program via POST commands and via environment variables.
|
||||
CGI socket I/O is redirected to <code>stdin</code> and <code>stdout</code> so that the CGI program only need to <code>printf()</code> to send its content back to the HTTP client.
|
||||
</p>
|
||||
<p>
|
||||
Another value to this THTTPD integration effort has been that THTTPD has provided a very good test bed for finding NuttX networking bugs.
|
||||
Several very critical networking bugs have been fixed with this 0.4.11 release (see the <a href="#currentrelease">ChangeLog</a> for details).
|
||||
Networking throughput has also been greatly improved.
|
||||
Anyone using NuttX networking should consider upgrading to this release.
|
||||
This release adds basic support for the STMicro STM32, Cortex-M3 MCU.
|
||||
The specific port is to the STMicro STM3210E-EVAL development board based around the STM32F103ZET6 MCU.
|
||||
Some highlights of this port:
|
||||
<ul>
|
||||
<li>This basic port includes boot-up logic, interrupt driven serial console, and system timer interrupts.<li>
|
||||
<li>The port includes a basic STMicro RIDE7 project that can be used to perform basic STM32 board bring-up
|
||||
(due to RIDE7 size limitations, it cannot be used for the full NuttX testing, unfortunately).<li>
|
||||
<li>Working, Tested Configurations: the NuttX OS test and the NuttShell (NSH) example.<li>
|
||||
</ul>
|
||||
</p>
|
||||
<p>
|
||||
It is planned to extend this basic STM32 port for the 0.4.12 NuttX release.
|
||||
Additional functionality needed for complete STM32 support includes:
|
||||
USB device driver, LCD driver and NX bringup on the development board's display and MicroSD support.
|
||||
An SPI driver and a DMA support was included in this 0.4.11 release, but is not yet tested.

Verified configurations are available for NuttX OS test and the NuttShell (NSH) example.

0.4.12 2009-10-17 Gregory Nutt <spudmonkey@racsa.co.cr>
|
||||
|
||||
* fs/fs_read.c and fs/fs_write.c. read() and write() to socket is the
|
||||
same as recv() and send() with flags = 0. Fixed!
|
||||
* net/recvfrom.c: Fix errors in return value from non-blocking socket read.
|
||||
* lib/lib_strcasecmp.c and lib/lib_strncasecmp.c. Use of post-incremented
|
||||
argument to macro caused strcasecmp() and strncasecmp() to fail.
|
||||
* lib/lib_strstr.c: Length of substring off by one causes false alarm
|
||||
sub-string matches.
|
||||
* arch/arm/src/lm3s/lm3s_ethernet.c: Fix errors in LMS6918 FIFO length
|
||||
handling. (1) The incorrect size of the ethernet header was being
|
||||
subtracted on outgoing messages (4 vs 14), which caused outgoing messages to
|
||||
be a little too long. (2) The size of incoming FIFO messages is 6 bytes
|
||||
larger than it expected (2 for the length and 4 for the FCS). The unhandled
|
||||
extra two bytes of length cause the driver to sometimes read one too many
|
||||
words from the received FIFO (corrupting the next queued receive packet,
|
||||
if any).
|
||||
* net/net_poll.c and net/uip/uip_tcpbacklog.c. Fixed an important race condition
|
||||
bug in polling for connections. The logic worked if the poll was inplace
|
||||
before the connection was received; but the poll failed to awaken if the
|
||||
connection was already pending in the backlog when poll() was called.
|
||||
* net/net_close.c. Fixed another important TCP/IP race condition bug: If
|
||||
the host closes the TCP connection just before the target calls close(), then
|
||||
the close operation may hang indefinitely!
|
||||
* net/net_tcppoll.c. Removed an unnecessary check for outstanding, un-ACKed
|
||||
data. The NuttX socket layer keeps track of ACKs and doesn't need this check;
|
||||
removing the check should improve write throughput
|
||||
* Add DEBUG configuration option to enable debug console output without disabling
|
||||
optimization (and vice versa)
|
||||
* Changed lots of occurrents of debug macro dbg() to lldbg(). dbg() uses
|
||||
stdout to output debug data. That works fine unless (1) the dbg() macro
|
||||
is interrupt logic and the interrupted task has redirected stdout! Most
|
||||
* net/uip/uip_tcpinput.c. Connection reference count was not being set correctly
|
||||
when a socket is created by accepting a new connection. Since the reference
|
||||
count is bad, such sockets are not successfully duplicated when being passed
|
||||
to new tasks.
|
||||
* net/net_clone.c. Similarly, after a socket is cloned, its reference count
|
||||
was not being initialized.
|
||||
* lib/lib_strstr.c. Improperly incremented pointer could cause comparison
|
||||
failures.
|
||||
* net/. Connection reference count must always be set to zero before calling
|
||||
uip_tcpfree() or it could trigger a DEBUGASSERT that verifies that the
|
||||
reference count is zero before freeing a connection structure.
|
||||
* net/uip/uip_listen.c. uip_accept() consulted the wrong list to find the
|
||||
listener on a socket. The previous logic worked most of the time, but
|
||||
occasionally picked the wrong listener.
|
||||
* net/net_close.c and net/net_sockets.c. Sockets were not being closed
|
||||
when a task exits. If many server tasks are created and exit without closing
|
||||
sockets (such as with CGI tasks), then eventually, you will run out of sockets.
|
||||
* netutils/thttpd. Basic functionality of THTTPD is complete. This includes
|
||||
serving up files from a file system and executing NXFLAT-based CGI programs
|
||||
and pipe the stdout back to the HTTP client.
|
||||
* arch/arm/src/stm32 and configs/stm3210e-eval. Added basic support for the
|
||||
STMicro STM32, Cortex-M3 MCU. The specific port is to the STMicro STM3210E-EVAL
|
||||
development board based around the STM32F103ZET6 MCU.
|
||||
* configs/stm3210e-eval/RIDE. Added a basic STMicro RIDE7 project that can be
|
||||
used to perform basic STM32 board bring-up (due to RIDE7 size limitations, it
|
||||
cannot be used for the full NuttX bring-up).
|
||||
* configs/stm3210e-eval/ostest. The STM32 now passes the basic NuttX OS test
|
||||
at examples/ostest. The rest should be a piece of cake.
|
||||
* configs/stm3210e-eval/nsh. Added NuttShell (NSH) example.
|
||||
* configs/stm3210e-eval/src/stm32102e-internal.h. Fix on-board LED GPIO definitions.
|
||||
* arch/arm/src/stm32/src/stm32/stm32_dma.c. Added DMA channel support for the STM32
