I flashed my Pixhawk Cube with the latest Developer’s Build (master), v1.8.2 and many parameters from Calibration (i.e., CAL_MAGX_EN…) were missing. The same parameters were there with Standard Build and Beta Testing build of 1.8.2. It had the identical issue (missing parameters) with the Custom Firmware build though I had not made any changes to the code. I have tested my setup with v1.8.1 and I have all the parameters.
Thanks,
Ben
