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.

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

2. Open a terminal and start a serial console on the corresponding port. On Linux, this is typically /dev/ttyACM0. For example:

   $ 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

3. Build and flash the Zephyr hello_world sample application:

   west build -b sam_e54_xpro samples/hello_world
   west flash
   

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

   Hello World! same_54_xpro
