What's your DISTRO, your MACHINE, TUNES and any other special configs? > I have had a search on the web but not found anything for recent Yocto > versions, only very old stuff. It's been working fine for years, hence no recent discussions. You may want to look into TI Processor SDK for AM335x - it's Yocto Project based Arago distro that is configured for Qt5-Wayland/Weston-SGX, but has been also tested with EGLFS QPA. -- Denys -- _______________________________________________ yocto mailing list yocto@yoctoproject.org https://lists.yoctoproject.org/listinfo/yocto
