  • Connect the USB type-A to microUSB cable to the CN30 connector of B79 SMARC carrier board on one side but wait to connect the other side to the Host PC.

  • Power on the B79 SMARC carrier board.

  • Start flashing the image on the SOM-SMARC-MX8M-Plus device via the following command:

$ sudo ./uuu flash.lst
