Hi Juozapas , I'm really excited to see that you can get the OpenGL ES working on the beagleboneblack. I have a beagleboneblack connected to a LCD touch panel and I have the SGX modules installed(followed instructins from Robert nelson's page). I'm trying to run QT dashboard example project. But the program errors out with the message that the program : Could not initialize egl display. I could not find answers related to this issue.
Did you happen to come across similar issue? I would appreciate if you can share some information.
