Is it possible that I may be having this same problem with a Navio@. I can’t anything to work I have tried reinstalling the firmware 3 times and I can’t get APM to launch. I keep getting the following error messge.

$ sudo ArduCopter-quad -C /dev/ttyAMA0

I think the problem discussed in this thread is unrelated.

For the past couple of months the only two reason for the issue you’re observing are either not a properly screwed down to Raspberry Pi Navio 2 or a hardware fault (extremely unlikely). I suggest looking into the former.

Moved to another thread.

Please provide a close-up photo of your hardware setup.
Were you able to run APM previously? When did this problem appear?

I have never been able to connect to APM, i even went as far as buying a new navio2 board and I’ still stuck at the same point as before. i have tried everything possible and nothing. Can it be becuse of the RFD 900+ telemetry radios? i have them set at 115200 which should work with them but even with different radios set at 57600 i get the exact same error.

  3. For finding out the issue, click Scan Now.
