That development board uses the STM32L4R9AI part.

The port of NuttX to Adafruit Metro M4 development board was released with NuttX-7/26.
|
||||
This board is essentially a advanced version of the Adafruit Metro board based on the SAMD21, but upgraded to the SAMD51, specifically the SAMD51J19.
|
||||
See the <a href="https://www.adafruit.com/product/3382">Adafruit</a> web page for additional information about the board.
|
||||
</p>
|
||||
<p>
|
||||
A fully-function, basic NuttShell (NSH) configuration was was available in this initial NuttX-7.26 release.
|
||||
That initial port verifies clock configuration boot-up logic, SysTick timer, and SERCOM USART for the serial console.
|
||||
The NSH configuration also includes use of the Cortex-M Cache Controller (CMCC) which give the SAMD51's Cortex-M4 a performance boost.
|
||||
</p>
|
||||
<p>
|
||||
Because of the similarity in peripherals, several drivers were brought in from the SAML21 port.
|
||||
Most have not been verified as of the NuttX-7.26 release.
|
||||
These unverfied drivers include: SPI, I2C, DMA, USB.
|
||||
Also refer to the NuttX board <a href="https://bitbucket.org/nuttx/nuttx/src/master/configs/metro-m4/README.txt" target="_blank">README</a> file for further information about the current state of the port.
