> So all that remains is SGX / OGL support too . . . Is this likely ? Robert¹s build script does do this for you now. Perhaps he will find a way to simplify the process when he has time. TI still have to add xorg support. Not sure when that is going to happen. I think that adding QT5 + Wayland to the BBB repository would be helpful. Several people are working on this so hopefully something will happen soon.
