Hello,

I have a 4D Systems LCD Panel (4dcape-43) connected to a beaglebone black running qnx.
I'm using the devg-omaplxx driver contained in the BSP (bsp-nto650-ti-beaglebone-sp1-trunk-201209071340).

A logic analyser connected to the lcd interface shows that every valid frame is followed by an empty one. Therefore the 
display is flickering.

I suppose Photon is only filling one buffer. The Datasheet for my TI am335 processor shows that the lcd controller reads
 from two alternating buffers using DMA.
Please reply if you have any idea concerning this error.

Regards,

Florian

Please don't hesitate to ask if you need further information.
