Since you have an A320 board, it's possible you may have been shipped an older one that did not ship with the BIOS needed for the 2200G. You may need to get a first gen Ryzen chip or one of the AM4 excavator APUs to do a BIOS update, or take the board to a computer store and see if they will update the BIOS for you. AMD did have a boot kit program where they send you a loaner A6 APU to let you flash the BIOS, but I'm not sure if that's still in effect.
