Flashing the device
The ExpLoRer has the Arduino bootloader on it. Flashing is supported by the standard RIOT "make flash" procedure.
Refer to https://github.com/RIOT-OS/RIOT/wiki/OpenOCD for building OpenOCD and make sure "cmsis-dap" and "hidapi-libusb" are enabled.
To build software for the ExpLoRer board we strongly recommend the usage of the GNU Tools for ARM Embedded Processors toolchain.
