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.

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.
