Hello!
Im working on custom Hardware, related to Beaglebone black. I compiled everything cross from source.
If I enable OpenGL and run an application, the screen turns black and nothing happens.
Here are my steps and environments:
Kernel:
3.12.15-rt25 (A testing 4.6.7 kernel behaves similar. Let me know, if you need kernel config or device tree options)
