Default Zephyr Peripheral Mapping:

• SERCOM2 USART TX : PB24
• SERCOM2 USART RX : PB25
• GPIO/PWM LED0 : PC18
• GPIO SW0 : PB31
• GMAC RMII REFCK : PA14
• GMAC RMII TXEN : PA17
• GMAC RMII TXD0 : PA18
• GMAC RMII TXD1 : PA19
• GMAC RMII CRSDV : PC20
• GMAC RMII RXD0 : PA13
• GMAC RMII RXD1 : PA12
• GMAC RMII RXER : PA15
• GMAC MDIO MDC : PC11
• GMAC MDIO MDIO : PC12
• SERCOM4 SPI SCK : PB26
• SERCOM4 SPI MOSI : PB27
• SERCOM4 SPI MISO : PB29
• SERCOM7 I2C SDA : PD08
• SERCOM7 I2C SCL : PD09
• USB DP : PA25
• USB DM : PA24

System Clock

The SAME54 MCU is configured to use the 32.768 kHz external oscillator with the on-chip PLL generating the 48 MHz system clock.

Serial Port

The SAME54 MCU has 8 SERCOM based USARTs with one configured as USARTs in this BSP. SERCOM2 is the default Zephyr console.

• SERCOM2 115200 8n1 connected to the onboard Atmel Embedded Debugger (EDBG)

PWM

The SAME54 MCU has 5 TCC based PWM units with up to 6 outputs each and a period of 24 bits or 16 bits. If :code:CONFIG_PWM_SAM0_TCC is enabled then LED0 is driven by TCC0 instead of by GPIO.

SPI Port

The SAME54 MCU has 8 SERCOM based SPIs.

I2C Port

The SAME54 MCU has 8 SERCOM based I2Cs. On the SAM E54 Xplained Pro, SERCOM7 is connected to a AT24MAC402 EEPROM and a ATECC508A Crypto Authentication device.

Programming and Debugging

.. zephyr:board-supported-runners::

The SAM E54 Xplained Pro comes with a Atmel Embedded Debugger (EDBG). This provides a debug interface to the SAME54 chip and is supported by OpenOCD.

Flashing

#. Build the Zephyr kernel and the hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: same54_xpro :goals: build :compact:

#. Connect the SAM E54 Xplained Pro to your host computer using the USB debug port.

#. Run your favorite terminal program to listen for output. Under Linux the terminal should be :code:/dev/ttyACM0. For example:

.. code-block:: console

  $ minicom -D /dev/ttyACM0 -o

The -o option tells minicom not to send the modem initialization string. Connection should be configured as follows:

• Speed: 115200
• Data: 8 bits
• Parity: None
• Stop bits: 1

#. To flash an image:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: same54_xpro :goals: flash :compact:

You should see "Hello World! same54_xpro" in your terminal.
