Finally got round to playing with the OpenROV control board. It looks like it will save lots of time.
Just had to set the fuse bits, upload the atmega 2560 bootloader, plug in the beagle bone black, apply power and connect a power switch and away she went 🙂
Command line string for setting fuse bits and installing the bootloader:
avrdude -c usbasp -p m2560 -P usb -b 115200 -e -u -U lock:w:0x3F:m -U efuse:w:0xFD:m -U lfuse:w:0xFF:m -U hfuse:w:0xDE:m
avrdude -c usbasp -p m2560 -P usb -b 115200 -V -U flash:w:mega2560boot.hex //(I changed the file name)
avrdude -c usbasp -p m2560 -P usb -b 115200 -U lock:w:0x0F:m

I am re inspired and hope to get the rov together in some form and through it in the water soon.
