This is primarily a bugfix release and includes some important corrections to the code:
<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.

Support for <a href="NuttXDemandPaging.html">on-demand paging</a> has been developed for the EA3131.
That support would all execute of a program in SPI FLASH by paging code sections out of SPI flash as needed.
However, as of this writing, I have not had the opportunity to verify this new feature.

<b>STATUS:</b>
This port is nearing he completion of development.
All code is complete for the basic NuttX port including header files for all AT32UC3* peripherals.
The untested AVR32 code was present in the 5.12 release of NuttX.
Since then, the basic RTOS port has solidified;
the port 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>)
and is under test now.
The basic, verified port will be released in NuttX-5.13.

A NuttShell (NSH) configuration is in place see the <a href="http://www.nuttx.org/NuttShell.html">NSH User Guide</a>).
Testing of that configuration has been postponed (because it got bumped by the Olimex LPC1766-STK port).
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 functionality, but I am not yet able to demonstrate that.
At present, I get nothing coming in the serial RXD line (probably because it is configured wrong or I have the MAX232 connected wrong).
</li>
</ul>
The basic, port (including the verified examples/ostest configuration) will be released in NuttX-5.13.
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.
