This port supports the TI &quot;Calypso&quot; MCU used in various cell phones (and, in particular,
by the <a href="http://bb.osmocom.org/trac/">Osmocom-bb project</a>).
Like the c5471, NuttX operates on the ARM7 of this dual core processor.
Board support is available for the Motorola C155 and W220 phones and for the Pirelli DP-L10 phone.

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:
(1) An OS test configuration that verifies the correct port of NuttX to the part and
(2) A barebones NuttShell (<a href="NuttShell.html">NSH</a>) configuration that can be used as the basis for further application development.
(3) A full-loaded NuttShell (<a href="NuttShell.html">NSH</a>) configuration that demonstrates all of the SAMA5D3x features.

</li>
</ul>
<p>
The following support was added in Nuttx 6.30:
</p>
<ul>
<li>
DMA support, and
</li>
<li>
PIO interrupts,
</li>
</ul>
<p>
And drivers for
</p>
<ul>
<li>
SPI (with DMA support),
</li>
<li>
AT25 Serial Flash,
</li>
<li>
Two Wire Interface (TWI), and
</li>
<li>
HSMCI memory cards.
</li>
</ul>
<p>
NuttX-6.30 also introduces full USB support:
</p>
<ul>
<li>
High speed device controller driver,
</li>
<li>
OHCI (low- and full-speed) and
</li>
<li>
EHCI (high-speed) host controller driver support.
</li>
</ul>
<p>
With NuttX-6.31, these additional drivers were added:
</p>
<ul>
<li>
A 10/100Base-T Ethernet (EMAC) driver,
</li>
<li>
A 1000Base-T Ethernet (GMAC) driver,
</li>
<li>
A Real Time Clock (RTC) driver and integrated with the NuttX system time logic
</li>
<li>
<code>/dev/random</code> using the SAMA5D3x True Random Number Generator (TRNG),
</li>
<li>
A Watchdog Timer (WDT) driver,
</li>
<li>
A Timer/Counter (TC) library with interface that make be used by other drivers that need timer support,
</li>
<li>
An ADC driver that can collect multiple samples using the sequencer, can be trigger by a timer/counter, and supports DMA data transfers,
</li>
<li>
A touchscreen driver based on the special features of the SAMA5D3 ADC peripheral,
An LCD controller (LCDC) frame buffer driver, and
</li>
<li>
A CAN driver (however, testing of the CAN has been delayed because of cabling issues).
</li>
</ul>
<p>
Additional board configurations were added to test and demonstrate these new drivers including new graphics and NxWM configurations.
These are expected in NuttX-6.32.
</p>
<p>
The following drivers and features were added in Nuttx 6.30:
DMA and PIO interrupts, drivers for SPI, AT25 Serial Flash, Two Wire Interface (TWI), and HSMCI memory cards included in NuttX-6.30.
NuttX-6.30 also introduces full USB support: High speed device controller driver, and OHCI (low- and full-speed) and EHCI (high-speed) host controller driver support.
Develop continues.
Additional driver developement is underway (include LCD and networking) and there should be available in NuttX-6.31.
Work is underway to provide a Image Sensor Interface (ISI) camera interface, a PWM driver, and NAND FLASH support.
