This is my last attempt to get this thing working. Python script clearly shows RCInput, Mission Planner sees nothing. Got the latest image for the Raspberry Pi and the latest Mission Planner.
Please help before I chuck this thing in the bin.

Looks like theres some permission issues, although running it with sudo doesn’t show this error.
I would start by having things updated

I guess it’s time to give up. I guess the Navio2 is near end of life now anyway.
Rob
End of life ? Not sure why.
The Navio2 is still very well supported both by Emlid and by ArduPilot. If behaves as well as any ArduPilot compatible flight controller, and IMHO it has a huge advantage of being able to run apps on the RPI, so dispensing the need of having an external Companion Computer alongside a PixHawk.
I have a PR open on ArduPilot that will make the Navio2 a much more versatile controller than any PixHawk, by allowing thousands of waypoints on a mission, instead of the 700ish a STM32 allows.
And there are a few apps, being developed to run on Companion computers that will run straight on the Navio2, such like APSync or Maverick, greatly extending the functionality and versatility of the Navio2.
From your screen I see that you are not using an updated version, which I strongly recommend.
edit: I’m not associated with Emlid. I really like what they done with the Navio2. Only criticism would be to have a updated version with the new JST-GH connectors, instead of those horrible DF-13’s

I’ve done all the updates I can. Is it possible I have an old firmware version (if that exists on these boards)?
I agree, I like the idea of the Navio2, i’ve just only got the thing working once, and it crashed and burnt out an ESC. I don’t blame the Navio2 for that, but would have thought getting the RCInput to work would be easy. Especially as I can see all 6 channels using the python script:
UPDATE: Using stretch has sorted the problem!

Thanks for the encouragement to not give up.
Happy New Year!
