| <p>There are ports to two Microchip SAMA5D3 boards:</p> |
| <ul> |
| <li><p><strong>Microchip SAMA5D3x-EK development boards</strong>. This is the port of NuttX |
| to the Microchip SAMA5D3<em>x</em>-EK development boards (where <em>x</em>=1,3,4, |
| or 5). These boards feature the Microchip SAMA5D3<em>x</em> microprocessors. |
| Four different SAMA5D3<em>x</em>-EK kits are available</p> |
| <ul class="simple"> |
| <li><p>SAMA5D31-EK with the |
| <a class="reference external" href="http://www.atmel.com/devices/sama5d31.aspx">ATSAMA5D31</a></p></li> |
| <li><p>SAMA5D33-EK with the |
| <a class="reference external" href="http://www.atmel.com/devices/sama5d33.aspx">ATSAMA5D33</a></p></li> |
| <li><p>SAMA5D34-EK with the |
| <a class="reference external" href="http://www.atmel.com/devices/sama5d34.aspx">ATSAMA5D34</a></p></li> |
| <li><p>SAMA5D35-EK with the |
| <a class="reference external" href="http://www.atmel.com/devices/sama5d35.aspx">ATSAMA5D35</a></p></li> |
| </ul> |
| <p>The each kit consist of an identical base board with different |
| plug-in modules for each CPU. All four boards are supported by NuttX |
| with a simple reconfiguration of the processor type.</p> |
| <p><strong>STATUS</strong>. Initial support for the SAMA5D3x-EK was released in |
| NuttX-6.29. That initial support was minimal: There are simple test |
| configurations that run out of internal SRAM and extended |
| configurations that run out of the on-board NOR FLASH:</p> |
| <ul class="simple"> |
| <li><p>A barebones NuttShell (<a class="reference internal" href="../../../applications/nsh/nsh.html#nsh"><span class="std std-ref">NSH</span></a>) configuration |
| that can be used as the basis for further application development.</p></li> |
| <li><p>A full-loaded NuttShell (<a class="reference internal" href="../../../applications/nsh/nsh.html#nsh"><span class="std std-ref">NSH</span></a>) configuration |
| that demonstrates all of the SAMA5D3x features.</p></li> |
| </ul> |
| <p>The following support was added in NuttX 6.30:</p> |
| <ul class="simple"> |
| <li><p>DMA support, and</p></li> |
| <li><p>PIO interrupts,</p></li> |
| </ul> |
| <p>And drivers for</p> |
| <ul class="simple"> |
| <li><p>SPI (with DMA support),</p></li> |
| <li><p>AT25 Serial Flash,</p></li> |
| <li><p>Two Wire Interface (TWI), and</p></li> |
| <li><p>HSMCI memory cards.</p></li> |
| </ul> |
| <p>NuttX-6.30 also introduces full USB support:</p> |
| <ul class="simple"> |
| <li><p>High speed device controller driver,</p></li> |
| <li><p>OHCI (low- and full-speed) and</p></li> |
| <li><p>EHCI (high-speed) host controller driver support.</p></li> |
| </ul> |
| <p>With NuttX-6.31, these additional drivers were added:</p> |
| <ul class="simple"> |
| <li><p>A 10/100Base-T Ethernet (EMAC) driver,</p></li> |
| <li><p>A 1000Base-T Ethernet (GMAC) driver,</p></li> |
| <li><p>A Real Time Clock (RTC) driver and integrated with the NuttX |
| system time logic</p></li> |
| <li><p><code class="docutils literal notranslate"><span class="pre">/dev/random</span></code> using the SAMA5D3x True Random Number Generator |
| (TRNG),</p></li> |
| <li><p>A Watchdog Timer (WDT) driver,</p></li> |
| <li><p>A Timer/Counter (TC) library with interface that make be used by |
| other drivers that need timer support,</p></li> |
| <li><p>An ADC driver that can collect multiple samples using the |
| sequencer, can be trigger by a timer/counter, and supports DMA |
| data transfers,</p></li> |
| <li><p>A touchscreen driver based on the special features of the SAMA5D3 |
| ADC peripheral, An LCD controller (LCDC) frame buffer driver, and</p></li> |
| <li><p>A CAN driver (Testing of the CAN has been delayed because of |
| cabling issues).</p></li> |
| </ul> |
| <p>Additional board configurations were added to test and demonstrate |
| these new drivers including new graphics and NxWM configurations.</p> |
| <p>These drivers were added in NuttX-6.32:</p> |
| <ul class="simple"> |
| <li><p>A PWM driver with DMA support</p></li> |
| <li><p>An SSC-based I2S driver</p></li> |

| <p><strong>Microchip SAMA5D3 Xplained development board</strong> This is the port of NuttX |
| to the Microchip SAMA5D3 Xplained development board. The board features the |
| Microchip SAMA5D36 microprocessor. See the <a class="reference external" href="http://www.atmel.com/devices/sama5d36.aspx">Microchip |
| Website</a> for additional |
| information about this board.</p> |
| <p><strong>STATUS</strong>. This port is complete as of this writing and ready for |
| general use. The basic port is expected to be simple because of the |
| similarity to the SAMAD3<em>x</em>-EK boards and is available in the NuttX |
| 7.2 release.</p> |
| <p>Most of the drivers and capabilities of the SAMA5D3x-EK boards can be |
| used with the SAMA5D3 Xplained board. The primary difference between the |
| ports is that the SAMA5D3x-EK supports NOR FLASH and NuttX can be |
| configured to boot directly from NOR FLASH. The SAMA5D3 Xplained board |
| does not have NOR FLASH and, as a consequence NuttX must boot into SDRAM |
| with the help of U-Boot.</p> |

| <p>There is a port in progress on one Microchip SAMA5D4 board:</p> |
| <ul> |
| <li><p><strong>Microchip SAMA5D4-EK/MB development boards</strong> This is the port of NuttX |
| to the Microchip SAMA5D4-MB Rev C. development board (which should be |
| compatible with the SAMA5D4-EK). These boards feature the Microchip |
| SAMA5D44 microprocessors with compatibility with most of the SAMA5D3 |
| peripherals.</p> |
| <p><strong>STATUS</strong>. At the time of the release of NuttX-7.3, the basic port |
| for the SAMA5D4-MB was complete. The board had basic functionality. |
| But full functionality was not available until NuttX-7.4. In |
| NuttX-7.4 support was added for the L2 cache, many security features, |
| XDMAC, HSMCI and Ethernet integrated with XDMAC, the LCDC, TWI, SSC, |
| and most of the existing SAMA5 drivers. Timers were added to support |
| <em>Tickless</em> operation. The TM7000 LCDC with the maXTouch multi-touch |
| controller are also fully support in a special NxWM configuration for |
| that larger display. Support for a graphics media player is included |
| (although there were issues with the WM8904 audio CODEC on my board). |
| An SRAM bootloader was also included. Refer to the NuttX board |

| </ul> |
| <p><strong>Development Environments:</strong> 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 performed |
| with the CodeSourcery toolchain (GCC version 4.7.3) in the Cygwin |
| environment under Windows.</p> |
