[meta-freescale] directFB and QT4 (OpenGL) on iMX6

[Milan Malich]

Hello,
I try to use directFB with QT4 (OpenGL) on Wandaboard (iMX6 DualLite) (Yocto
Dora branch). Is there anyone who use opengl acceleration on framebuffer 
without X11 or Wayland? Some Qt examples was working via QWS plugin but when
I try use OpenGL (for example switch render in app svgviewer to OpenGL) it 
was crash (only I can see is freeze cursor on terminal text). hellogl_es2 
crash on startup (freeze cursor on terminal text). df_dok was running 
correctly. There are some tutorials or documentation how to run directFB and
OpenGL?
Thank you
