OMAP DM3730: omapdss DISPC error: OCP_ERR

Hi,

I'm facing a critical issue in OMAP display controller.

I'm using Video overlay1 for camera(video) streaming.

When i'm allocating buffer using MMAP for dss, i'm able to see the video output in dvi correctly.

But when using USERPTR, (allocate buffer in camera using MMAP and pass the same buffer to dss as USERPTR) the video output got collapsed.

I'm using linux 2.6.35 kernel. Please help me to solve this issue.

Thanks in advance,

Balaji P
