Flashing
OpenOCD
Programs are loaded onto the SAM E54 Xplained Pro with the onboard Atmel EDBG hardware programmer, using the openocd command line utility program to perform the board flashing. You must install OpenOCD before you will be able to flash the SAM E54 Xplained Pro board with your TinyGo code.
- Plug your SAM E54 Xplained Pro into your computer’s USB port.
- Build and flash your TinyGo program using
tinygo flash -target=atsame54-xpro [PATH TO YOUR PROGRAM]
Notes
You can use the USB port to the SAM E54 Xplained Pro as a serial port. UART0 refers to this connection.
