My new APM 2.5 with ArduCopter V2.9.1b connects to Mission Planner and downloads MAV data. HUD/Status does not update. Most test in terminal run, except setup|accel and test|ins fail, they halt/hang after Init Gyro. I assume this is a hardware problems? I have had it 3 month and just installing/testing it. I am good with electronic and software. Is there other troubleshooting I can do confirm it is an issues with the Gyro chip?
