Programming and Debugging
The SAM E54 Curiosity Ultra 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. SERCOM1 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:$ 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_worldsample application:west build -b sam_e54_cult samples/hello_world west flash
Observe output on the terminal. If everything is set up correctly, you should see:
Hello World! sam_e54_cult
