<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.
+ 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>
- 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.
+ 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.

- * 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.
