UAV novice here, just got around to firing up my new 900MHz 3DRs. Coming from an IT background, I thought I'd check the "Upload Firmware" button while on the CTRL+A radio config page. Epic fail. See screenshot. As it stands, the red LED on ground radio is continuously lit and appears to be dead to the world (probably something to do with the 'erase program flash' step ;-) Any ideas on how to fix?…
