Hi,
We are using one custom board having am5728 sitara processor. We have connected LCD and HDMI out connector but "kmscube" application is not executing successfully it is showing following error. According to my understanding It seems some problem between primary and secondary display device. We want to use LCD as primary and HDMI as secondary display device.
/* Result of kmscube */

Please Tell me how to resolve this issue, if We are using LCD and HDMI stand alone, In that case it is working fine. We are facing this issue only when we using both of them together.
Thanks & Regards
