This is the port of NuttX to the Atmel SAMA5D3x-EK development boards (where x=1,3,4, or 5).
These boards feature the Atmel SAMA5D3 microprocessors.
Four different SAMA5D3x-EK kits are available
</p>
<ul>
<li>SAMA5D31-EK with the <a href="http://www.atmel.com/devices/sama5d31.aspx">ATSAMA5D1</a></li>
<li>SAMA5D33-EK with the <a href="http://www.atmel.com/devices/sama5d33.aspx">ATSAMA5D3</a></li>
<li>SAMA5D34-EK with the <a href="http://www.atmel.com/devices/sama5d34.aspx">ATSAMA5D4</a></li>
<li>SAMA5D35-EK with the <a href="http://www.atmel.com/devices/sama5d35.aspx">ATSAMA5D5</a></li>
</ul>
<p>
The each kit consist of an identical base board with different plug-in modules for each CPU.
An option 7 inch LCD is also available.
All four boards are supported by NuttX with a simple reconfiguration of the processor type.
</p>
<p>
There is also the SAMA5D3FAE-EK bundle includes everything: The base board, all four CPU modules, and the LCD.
</p>
<ul>
<p>
<b>STATUS</b>.
Initial support for the NUC120 was released in NuttX-6.29.
This initial support is very minimal:
There are simple test configurations that run out of internal SRAM and two configurations that run out of the on-boar NOR FLASH:
(1) An OS test configuration that verifies the correct port of NuttX to the part and
(2) a NuttShell (<a href="NuttShell.html">NSH</a>) configuration that might be the basis for further application development.
As of this writing, more device drivers are needed to make this a more complete port.
Refer to the NuttX board <a href="http://sourceforge.net/p/nuttx/git/ci/master/tree/nuttx/configs/sama5d3x-ek/README.txt">README</a> file for further information.
</p>
<b>Development Environments:</b>
1) Linux with native Linux GNU toolchain, 2) Cygwin/MSYS with Cygwin GNU toolchain, 3) Cygwin/MSYS with Windows native toolchain, or 4) Native Windows.
All testing has been perfomed with the CodeSourcery toolchain (GCC version 4.7.3) in the Cygwin environment under Windows.
