I Installed the Development on my host machine and builded a Kernel with this tutorial:

https://github.com/STMicroelectronics/meta-st-stm32mp/blob/dunfell/recipes-kernel/linux/linux-stm32mp/README.HOW_TO.txt

but afther the reboot my scren keeps beeing black.

I updated the kernel because the development tool has a newer kernel and i wanted to make a kernel module so i wanted to update.

I might help if you add debug UART logging output.

Hi @SAman.1​ 

Please precise version of Kernel, tf-a, U-boot you are using.

Pay attention that you might use a consistent OSTL version ( eg V1.2 or V2.0 or V2.1 )

@Community member​ My old Kernel was on version 4.19.9 and i wanted to update to 5.4.56. On my board i only installed the started package so my YOCTO was running. beside that i have no changes on my system.

Hi @SAman.1​ 

You can't update only kernel to 5.4.56. You need to take also TF-A / Uboot version from V2.1.
