Ardurover V4.2.0 Config Error: INS: unable to initialise driver

Hi everyone,

I have successfully flashed Ardurover V4.2.0 onto my Omnibus F4 through Betaflight, but I am running into an error when connecting it to Mission Planner. The error code in messages is - Config Error: INS: unable to initialise driver. I’ve tried flashing other modes such as Arduplane V4.2.1, but again the same error message shows up. I have not soldered or touched anything on the board yet, it is brand new out of the box. Wondering if anyone have a solution to this? Thanks!
