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 same54-xpro is using EDBG.
On Linux you will have to add a udev rule for hidraw, like
Supported Toolchains
For using the same54-xpro board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
