BlueOS - Parameters not loading correctly, don't calibrate

Blue Robotics Software
1

QGroundControl gives me errors including that my Compass and 3D Accl are not calibrated.

I’ve been re-setting the Boat after some difficulties. It has worked fine in the field in the past.

When I use either the Quick and the normal compass calibration option

I get the following errors:
‘Calibration failed: Error: timed out waiting for answer for
MAV_CMD_DO_START_MAG_CAL’
and
‘… MAV_CMD_FIXED_MAG_CAL_YAW’

But that is when the Ardupilot parameters load correctly, which usually they do not. Often I start the Blueboat. BlueOS shows the CPU running at >90%, and will stay that high indefinitely. Parameters fail to load.

I need to experiment more to understand these two problems and when they each arise. My general problem is one of Parameters, and my general one is that QGC needs these to operate.

I’ve fixed the problem.

The issue seemed to be me loading a saved autopilot parameters file. I would try this after flashing the pi SD card. Loading the parameters would fail. I’d then see a variety of parameter-related errors, including not being able to reset the parameters. Re-flashing and skipping the step of loading the saved file has resulted in no errors and normal calibration.
