<b>STATUS:</b>
As of this writing (2015-03-09), this is a work in progress.
The basic port is code complete and just entering into the test phase.
The basic port includes a configuration for the NuttShell (NSH) and a serial console.
Additional drivers are expected.
The basic port is complete and there are several different, verified configurations available.
All configurations use the the NuttShell (NSH) and a serial console.
The first release of the SAMV71-XULT port is expected in NuttX-7.9.
</p>
<p>
Additional drivers, with status as of 2015-03-29, include:
</p>
<ul>
<li>PIO configuration, including PIO interrupts,</li>
<li>On-board LEDs and buttons,</li>
<li>DMA,</li>
<li>SDRAM (not yet functional),</li>
<li>UART/USART-based serial drivers, including the NuttShell serial console,</li>
<li>High Speed Memory Card Interface (HSMCI) with support for the on board SD card slot,</li>
<li>SPI (not fully tested),</li>
<li>TWIHS/I2C, with the support for the on-board serial EEPROM,</li>
<li>SSC/I2S (not fully tested),</li>
<li>Ethernet MAC (works only with caches disabled),</li>
<li>USB device controller driver (not yet functional).</li>
</ul>
</p>
Refer to the NuttX board <a href="http://sourceforge.net/p/nuttx/git/ci/master/tree/nuttx/configs/samv71-xult/README.txt">README</a> file for further information.

A port is in available for the PIC32MZ Embedded Connectivity (EC) Starter Kit.
There are two configurations of the Microchip PIC32MZ EC Starter Kit:
</p>
<ol>
<li> The PIC32MZ Embedded Connectivity Starter Kit based on the PIC32MZ2048ECH144-I/PH chip (DM320006), and</li>
<li> The PIC32MZ Embedded Connectivity Starter Kit based on the PIC32MZ2048ECM144-I/PH w/Crypto Engine (DM320006-C).</li>
</ol>
<p>
See the <a href="http://www.microchip.com">Microchip</a> website for further information.
</p>
<ul>
<p>
<b>STATUS:</b>
This is a collaborative effort between Kristopher Tate, David Sidrane and myself.
The basic port is functional and a NuttShell (NSH) configurqation is available.
The first official is expected in NuttX-7.9.
Current efforts are focused on driver development.
Many drivers port simply from the PIC32MX; others require more extensive efforts.
Driver status as of (2015-03-29) is provided below:
<p>
<ul>
<li>I/O ports include I/O port interrupts</li>
<li>UART serial driver that provides the NSH console,</li>
<li>Timer,</li>
<li>I2C (untested),</li>
<li>SPI (untested),</li>
<li>On-board buttons and LEDs,</li>
<li>Ethernet (code complete, but not yet functional),</li>
</ul>
