Pre flight check

I have created a .px4 firmware file by cloning px4 Git-hub repository, which worked fine (WSL-Linux), but after I uploaded it to pix-hawk using Q-ground control, IT fails prechecks even after Calibration (Accel. 0 inconsistent, attitude fails(yaw, roll), pitch ) at the same time if I upload stable version from QGC it works fine, please Guide.

Sounds like there is something wrong with the firmware you created. Hard to say without seeing your changes.

Really appreciate it…Thank You,…There were no changes made by me, I followed exact guidelines except one thing that I uploaded fmu-v3 using QGC, selections were PX4 pro—>custom firmware ---->px4_fmu-v3_default (Generated using cloned Git-hub repo).

With what changes? And what sort of hardware are you using?
