Parameter automatically reset to factory defaults after a preflight reboot

On 7/20 before a flight test, a preflight reboot changed all the parameters I had set to default values. I have never seen this issue before. This is a custom version of v3.6-rc6. the tlog file can be found at:

Any help would be highly appreciated.

Yes, my pixhawk sometimes happened, with different firmware and different hardware, seems something not stable of FRAM ic, dont know if the reason is the strike arc when connecting the battery.

@FireFly not sure. Happened to me last week too :confused:

Which hardware are you using?

I’m using the Pixhawk Cube
