### Flash the board
|
|
|
|
The board is flashed using its on-board [boot loader](https://github.com/adafruit/uf2-samdx1).
|
|
|
|
The process is automated in the usual `make flash` target.
|
|
|
|
If RIOT is already running on the board, it will automatically reset the CPU and enter
|
|
the bootloader.
|
|
If some other firmware is running or RIOT crashed, you need to enter the bootloader
|
|
manually by double tapping the board's reset button.
|
|
|
|
Readiness of the bootloader is indicated by LD1 pulsing in red.
|
|
|
|
### Accessing STDIO
|
|
|
|
The usual way to obtain a console on this board is using an emulated USB serial port.
