When I try and update the Ardupilot firmware on my pixhak4 I get the following error message in a pop up window “Parameters are missing from firmware. You may be running a version of firmware which is not fully supported or your firmware has a bug in it. Missing params: 1:r.BATT_FS_LOW_ACT, 1:r.BATT_LOW_VOLT, 1:r.BATT_LOW_MAH”
Additionally, when I try and calibrate the compass it fails to calibrate any time.
I am pretty new to this hardware so any help would be awesome.
