This 60<sup>th</sup> release of NuttX, Version 5.13, was made on November 9, 2010 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>.
</p>
<p>
This is primarily a bugfix release and includes some important corrections to the code:
Headlines for this release include:
<ul>
<li>
Fixed an important error in the signal trampoline logic. Essentially,
interrupts are re-enabled while the signal handler executes, but the
logic to re-disable the interrupts before returning from the signal
handler trampoline was missing. Under certain circumstances, this
can cause stack corruption. This was discovered by David Hewson on
an ARM9 platform, but since the code has been leveraged, the bug has
been propogated from ARM to Cortex-M3, AVR32, M16C, SH1, ZNEO, eZ80,
Z8, and Z80 -- almost every architecture. The correction has been
incorporated for all architectures but only verified on a few.
</li>
<p>
AVR32, www.mcuzone.com AVR32DEV1
<ul>
<p>
The port for the www.mcuzone.com AVRDEV1 board based on the Atmel
AT32UC3B0256 MCU was (almost) fully integrated. The port now
successfully passes the NuttX OS test (examples/ostest). A
NuttShell (NSH) configuration is in place (see the
<a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Testing of that NSH configuration, however, has been postponed
(because it got bumped by the Olimex LPC1766-STK port -- see below)
</p>
<p>
Current Status: I think I have a hardware problem with my serial
port setup. There is a good chance that the NSH port is complete
and functional, but I am not yet able to demonstrate that. At
present, I get nothing coming in the serial RXD line (probably
because the pins are configured wrong or I have the MAX232
connected wrong).
</p>
<p>
A complete port will include drivers for additional AVR32 UC3
devices -- like SPI and USB --- and will be available in a later
release, time permitting.
</p>
</ul>
</p>
<p>
Other notable changes in NuttX-5.12 include:
<ul>
<li>
A complete port for the AVR32 (AT32UC3B0256) is incorporated in the
source tree. Testing of this port is underway now. This release
was made before verifying this port in order to get the important
bugfix in place.
</p>
</li>
<li>
Other miscellaneous bugfix and enhancements as noted in the ChangeLog.
<p>
LPC1766, Olimex LPC1766-STK
<ul>
<p>
Support for the Olimex-LPC1766 is newly added to NuttX and is
still undergoing development, test, and integration. Verified
configurations for the NuttX OS test and for the NuttShell (NSH,
see the <a href="ttp://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Additional USB configurations are in the release as well, but
they have not yet been verified. Goals for NuttX-5.14 include:
(1) An Ethernet driver, (2) Verified USB support, and (3) SD
card support.

* arch/avr - Add a place to support AVR family processors.
* arch/avr/include/avr32 and arch/avr/src/avr32 - Add support for AVR32
(all of the AVR32 is a work in progress).
* arch/avr/include/at32uc3 and arch/avr/src/at32uc3 - Add support
for the AVR32 UC3A/B family of AVR32 MCUs.
* confgs/avr32dev1 - Add support for the Atmel AVR32DEV1 board featuring
the AT32UC3B0256 MCU. This board is produced by www.mcuzone.com.
* include/stdlib.h, lib/Makefile, lib/lib_abs.c, lib/lib_labs.c,
lib_labs.c, lib_llabs.c, lib_imaxabs.c - Add abs(), labs(), llabs(), and
imaxabs().
* Add include/inttypes.h
* arch/hc/src/mc9s12ne64 - This hcs12 port grew a few more files. But it
is still a long way from complete.
* arch/*/src/*/*_sigdeliver.c - Fixed a serious error in the signal
trampoline logic. Essentially, interrupts are re-enabled while the
signal handler executes, but the logic to re-disable the interrupts
before returning from the signal handler trampoline was missing. Under

by Michael Hrabanek.
* Fix wild, consistent naming error. For some reason, I called the at32uc3*
parts at91uc* everywhere. Fixed by changing lots of files and directories.
* configs/avr32dev1/ostest - The AVR32 port now successfully passes the
examples/ostest. We have a good AVR32 port!
* configs/avr32dev1/nsh - Added a configuration to support the NuttShell
(NSH). As of this writing, here is a problem receiving serial data (this
is, very likely, my hardware setup).
* lib/lib_open.c - Fix an error in fdopen when a valid file desciptor does
not refer to an open file.
* configs/olimex-lpc1766stk - Add support for the Olimex LPC1766-STK
development board. The OS test and NSH configurations (only) have been
