Using UART
This board doesn't open an UART or serial interface threw the USB automatically, and the USB device driver hasn't been implemented to RIOT yet. Therefore, to open an UART interface one hast to connect a usb/ttl converter to the UART3 pins PB11 (RX3) and PB10 (TX3).
Flashing the device
The standard method for flashing RIOT to the nz32-sc151 is using dfu. On linux you must get dfu-util package v.8.0 or newer. You can try:
but most repos install older versions, therefore you should clone from dfu- util and follow building instructions HERE.
Once dfu-util is installed you can just flash as a normal board, although sudo privileges are required.
NOTE: this only works for linux, for windows you can use ST Microelectronics DFU Bootloader although you will need to build the files independently.
