Connect the device to your Micro-USB cable using the port labeled as DEBUG USB.
The standard method for flashing RIOT to the same54-xpro is using edbg.
by calling: make BOARD=same54-xpro -C tests/leds flash
Note that on Linux, you will need libudev-dev package to be installed.
Users can also use openOCD to flash and/or debug the board using:
PROGRAMMER=openocd make BOARD=same54-xpro -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
