Stm32mp157-dk2 chromium with debian 11

Hi, I’ve followed: Debian: Getting Started with the STM32MP157 to build debian image. Then I’ve installed chromium and xserver etc but seems I cannot start xserver as it reports:

(EE) 
Fatal server error:
(EE) Cannot run in framebuffer mode. Please specify busIDs        for all framebuffer devices
(EE) 
(EE) 

I’ve tried to install also weston and can run weston but I cannot run chromium it returns:

debian@arm:~$ sudo chromium --ozone-platform=wayland --no-sandbox google.com
error: XDG_RUNTIME_DIR is invalid or not set in the environment.
[4944:4944:0323/075659.664603:ERROR:wayland_connection.cc(186)] Failed to connect to Wayland display: No such file or directory (2)

[4944:4944:0323/075659.665434:ERROR:env.cc(255)] The platform failed to initialize.  Exiting.

Does anybody have an idea how to make it working please? Thanks.

Hi @marek.belisko i’m not aware of anyone working on the drm/libdrm/mesa interaction for this device on mainline, thus we to make this work, you need to use ST’s speical drivers from here still: meta-st-stm32mp/recipes-graphics at kirkstone · STMicroelectronics/meta-st-stm32mp · GitHub
