Flashing the device

Connect the device to your Micro-USB cable using the port labeled as DEBUG USB*.

The standard method for flashing RIOT to the board is using OpenOCD. by calling: make BOARD=same51-curiosity-nano -C tests/leds flash

On Linux you will have to add a udev rule for hidraw, like

bash
echo 'KERNEL=="hidraw*", SUBSYSTEM=="hidraw", MODE="0664", GROUP="plugdev"' \
    | sudo tee -a /etc/udev/rules.d/99-usb.rules
sudo service udev restart
