Hello.
I have a Cube Orange + running ArduCopter 4.6.3. I am getting a message
Config Error: Failed to update IO firmware
I switched BRD_IO_ENABLE to 2 no firmware and I get
PreArm: IOMCU is unhealthy

Cube shows up and connects to mission planner normally and I am able to configure and setup everything otherwise so far. Wish I could provide more helpful information. I’m not sure about this one.

Hold down the safety switch while booting. If that doesn’t work contact CubePilot.
