Rover-4.2.0-rc3 released for beta testing

Rover-4.2.0-rc3 has been released for beta testing and can be downloaded/installed using MP or QGC’s beta firmwares links.

The changes vs 4.2.0-rc2 are in the release-notes and also copied below.

  1. Bug fixes
    a) Blended Z axis accel calculation fix when not using first IMU
    b) Custom compass orientation for DroneCAN compasses

We are really very close to the 4.2.0 stable release I think so any and all feedback is greatly appreciated!


on Matek H743 I had to change INS_ENABLE_MASK manually to 15 to enable the 4th IMU.
Otherwise second IMU1 (MPU6000) is not detected.
It is a board with ICM_20602.
Same for Rover and Copter.

MP selection offers only three IMUs:

Thanks for the report. I’ve added it to the 4.2 issues list and we will run over it at tomorrow’s dev call and hopefully update the INS_ENABLE_MASK param description.


The parameter description has been corrected in master (aka “latest”) so this fix will go out with the next beta release. That might actually be 4.2.1 but in any case… it’s on the way.

Txs again for the report.
