SAM E54 Xplained Pro

Overview

The SAM E54 Xplained Pro evaluation kit is ideal for evaluation and prototyping with the SAM E54 Cortex®-M4F processor-based microcontrollers. The kit includes Microchip’s Embedded Debugger (EDBG), which provides a full debug interface without the need for additional hardware.

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
