After having Sd card issues, I decided to wipe and re install Tinybooter and firmware. Which I may add I have done before on this board.
I got as far as erasing which went fine, was asked to reset the board and now got a white screen!! When I plug my unit into my pc, i get a unknown device instead of the standard GPS Camera detection.
Yes, I have an external power source supplying 12v.
Ok, I have tried your steps and get a an error from winwdows
