The board does not have a micor-USB port. The USB C port should be used to flash the board.
I could talk to Auvidea’s support and this is the procedure to flash the board:
- Connect pin 7 (Force Recovery) and 8 (GND) of the J32 on the board to put the board in Force Recovery mode
- Connect the USB C to a Linux computer (wait a little bit and run
lsusb. You should seeNVIDIA Corp.) - Follow the setup procedure from the Software Installation Guide (https://auvidea.eu/download/Software)
This worked for my board (JN30D-Nano)
