openembedded-devel@lists.openembedded.org is better place (see README
file)

I've no experience with wandaboard, but few people asked about it with
relation to qt5, so maybe someone will respond on ML.

This works on my SabreLite which I built without X11 support.  I did not
use any of your QT_xxx exports, only this command line.

   # Qt5_CinematicExperience -platform eglfs -plugin tslib:/dev/input/touchscreen0

Not sure what omap3 board specifically that is, but meta-qt5 was successfully 
tested on another TI platform with OpenGLES on SGX - AM335x. No X11 though.
