[yocto] Fwd: iMX6UL - QtQuick - QtQuick2DRenderer

[Andreas Cord-Landwehr]

Hi, one point I noticed directly, you should only use one "-", i.e. 
"-platform linuxfb" . Moreover, best check with "export QT_DEBUG_PLUGINS=1" 
that linuxfb is located and loaded correctly.
Only if all of this works fine, you should start looking into the compile 
options.

Cheers,
Andreas
