Kernel panic during startup

uouox · ‎2021-12-30

Hi I built the linux kernel by following the steps on the stm32mpu wiki web. All default configuration except enabled earlyprintk.

However, when I restart the system, it does not work any more.

This is the error in boot log.

...

Any hint? The board is stm32mp157f-dk2

Thanks

Hi @uouox ,

Could you please elaborate further if you used Developer package or Distribution package for rebuild ?

What ecosystem / kernel version ?

Are you using default Device Tree as per delivered by ST ?

Thx

Olivier
