iSpindel: User exception (panic/abort/assert)

[LeMaYa]

I'm assembling two iSpindels at the moment but one is throwing "User exception (panic/abort/assert)" in the boot process.

I followed the FAQ for " What should I do if my iSpindel isn't working properly after flashing it with the firmware? "
but it's still throwing the exception. The other one is booting without any issues and I'm able to connect to the AP.

HTerm output of a reset of the unmounted M1 mini.
