I pulled a few wires in the field from my minimOSD yesterday and seem to have fried something in my APM2.0 and minimOSD. Given the camera/Vtx is 12v, I'm guessing something might have touched a pin it shouldn't have... the only cables touched were the minimOSD telemetry input and the video IN side of the OSD.
I can no longer connect the APM 2.0 to the MP via USB or using 3DR radios, or get anything on the OSD except clean video feed (no waiting for MAV link messages etc).
I already had a busted diode so had to power the input and output rails via a separate UBEC.
The APM2.0 and minimOSD both seem to start up with various power and other lights working, but can't talk to anything...
Is it all toast?
