Navio / Edge Hardware

Navio2, did an upgrade/update, asked for rcio upgrade - but doesn’t seem to stick, it keeps asking for and going through an upgrade everytime i start ardupilot.

sudo emlidtool rcio update -f

Hi @kwatkins,

Could you please post here the output of readlink -f /usr/bin/arducopter command?

Is there any running ArduPilot service (arducopter, arduplane or ardurover)?

Hi Tatiana, it seems to work now - I think it had to do with not having enough power as I was directly plugging in the usb port for power.

$ readlink -f /usr/bin/arducopter
/opt/ardupilot/navio/arducopter-3.5/bin/arducopter

Hi @kwatkins,

Glad to hear it works!

If you face the issue again, try to disable all ardupilot services, reboot the RPi and run emlidtool after rebooting.
