"Could not find DRM device!" on VIM3L

I can’t run my application which uses EGLFS… it returns “Could not find DRM device!”

I could run it in EdgeV linux-4.4 with no problems, but it is not working on VIM3L linux-4.9 (the only option in fenix)

I need help with this asap.

Thanks! @numbqq

Edge-V has X11 GPU and DRM support.

But for VIM3/VIM3L, there is X11 GPU support, only has fbdev, and there is no DRM support for current image.

Will it have DRM support in the next release?

Maybe not. If you want to use DRM, you can refer this dts to add DRM support. But I’m not sure whether it works.
