How to make my STM32M157C-DK2 to work?

[VFlig.1508]

Hello, I try to push the linux Kernel to STM32MP157C-DK2 board. I have made the reboot of my board. After the reboot I don't know why the screen of my board turns on then I can see the logo of ST and then my screen turns off. How can I correct that. Thanks for help

Hi @VFlig.1508​ 

It looks like the known display issue that may appears on some DK2 boards.

This issue is corrected if you use the latest OpenSTLinux Openstlinux-4.19-thud-mp1-19-10-09
