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 buildroot config option is name BR2_PACKAGE_RPI_FIRMWARE_INSTALL_DTB_OVERLAYS, do not forget to do a full re-build of the rpi-firmware package after enabling... For inclusion of the overlay files to the target/SD-card boot/first partition check/add the 'rpi-firmware/overlays' entry in the genimage file (see e.g. board/raspberrypi3/genimage-raspberrypi3.cfg for an example)...

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.
