Connections and IOs

The SAM E54 Xplained Pro User Guide_ has detailed information about board connections.

Programming and Debugging

The SAM E54 Xplained Pro features an on-board Microchip Embedded Debugger (EDBG), which provides both a standard debug interface and a virtual serial port used as the Zephyr console. SERCOM2 of the ATSAME54P20A MCU is configured as a USART for console output.

#. Connect the board to your host machine using the debug USB port.

#. Open a terminal and start a serial console on the corresponding port. On Linux, this is typically /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

#. Build and flash the Zephyr hello_world sample application:

.. zephyr-app-commands:: :zephyr-app: samples/hello_world :board: sam_e54_xpro :goals: flash :compact:

#. Observe output on the terminal. If everything is set up correctly, you should see:

.. code-block:: console

  Hello World! same_54_xpro
