Hello,

I just upgraded my starling 2 max to SDK 1.4 and also did an apt upgrade && apt update.  I ran the voxl-configure-mpa routine and received Missing /data/px4/param/parameters_bar_tc.cal message.  Looking at the calibration procedures in the documentation which procedure calibrates the baro?  Camera's, IMU, or Horizon?  Thanks.

@Kory4Drone Barometer temperature calibration is optional, but in some cases it can improve performance. You can run the barometer temperature calibration directly from the command line on VOXL 2: `baro_temp_cal`. Or you can run it from voxl-portal.
