However on the buildroot install, I do not find any files that match vc4-kms-v3d*. I've searched for and enabled additional items in the buildroot config that might be related, but nothing has helped yet.

The application runs fine when I use the platform plugin linuxfb. But when I try to use eglfs I'm getting the error that the DRM Device is not found. I see this error message mentioned often when doing a search, but so far have not found any solution that works for me.
