He has figured out that it is possible to flash the DVMega firmware using the Rpi itself with the DVMega still in situ by wiring the reset pin of the ATMEGA328 directly to a spare GPIO port and then using (a slightly modified version of) avrdude to flash the hex file straight over /dev/tty AMA0.I've tried this and it worked, but there are no guarantees. The same procedure works just as well on a single band DVMega….
