I am facing one issue, When I install the PX4 firmware to my Pixhawk6C board then it is running fine, the moment I install Ardupilot firmware (Latest Arducopter). It shows the Config Error: Failed to update IO firmware.
I have tried all possible options but not able to solve the issue, I have tried putting the board to DFU mode and then flashing the bootloader but still the problem is same.
Are you using MissionPlanner?
Is the board recognised as a Pixhawk 6C and the correct firmware installed during the process?
Version 4.5.7 “Official” ?
Have you tried updating the bootloader from in MissionPlanner (the easy way) ?
I’m checking because when we say “Latest” it means an unreleased version that is still under development. I suppose you mean 4.5.7
It’s odd because the 6C has been out a long time. I dont have one to test.
Hopefully someone else does have one and confirm what works and what does not.
