For the starters, check this out! Not really what you want, but maybe good starting point. https://github.com/ZoranStojsavljevic/bbb-yocto https://github.com/ZoranStojsavljevic/bbb-yocto/blob/master/bbb-yocto.sh Zoran _______ On Wed, Jul 24, 2019 at 7:54 PM Andy Pont <andy.p...@sdcsystems.com> wrote: > > I am trying to build a Yocto (warrior) image for the AM335x using meta-ti and > meta-qt5 that will render directly to the GPU.
