Issue running GUI application on stm32mp257 due to Vulkan error

Hi everyone, for learning purposes, I’m trying to build meta-doom ( https://github.com/JPEWdev/meta-doom ) for stm32mp257 DK. I previously tried it for RPi4 and after some minor fixes I was able to do it for nanbield/mickledore poky version. I chose those versions since meta-doom is only compatible with them. What I established it is possible to run it and it still works.

My setup for stm32mp2 version is that I cloned mickledore repo manifest and integrated meta-doom layer. Doom wouldn’t build for wayland, so I had to change my display manager to X11. It’s not directly supported but still possible (source: https://community.st.com/t5/stm32-mpus-embedded-software-and/how-to-setup-x11-in-the-distro-instead-of-wayland-on-stm32mp1/td-p/741125 )

Now gzdoom builds, and I’m able to execute on target. However, after uploading proper WAD I get this error:

> 
> 
> 
> no vulkan device found supports minimum requirements of this application
> 
> 

I installed vulkan-loader and vulkan-tools into the image and vulkaninfo gives me following information:

> 
> 
> 
> root@stm32mp25-disco:~# vulkaninfo WARNING: [Loader Message] Code 0 :
> loader_scanned_icd_add: Driver /vendor/lib/libvulkan_VSI.so.1.3.3 supports
> Vulkan 1.3, but only supports loader interface version 2. Interface

> #LDP_DRIVER_7) WARNING: [Loader Message] Code 0 :
> terminator_CreateInstance: Driver /vendor/lib/libvulkan_VSI.so.1.3.3
> supports interface version 2 but still exposes VkSurfaceKHR create/destroy
> entrypoints
> 
> 

I’m at a loss on what to do at this point. There seems to be some version mismatch but I can’t figure out how to solve it. And since it worked flawlessly for RPI4 I think this is some configuration related issue, but I couldn’t pinpoint it.
