I am using mcsdk_video_2_2_0_23 and dspc8682 (8 c6678)
Sometimes the mcsdk video demo example stops working showing the following error
"cmem_drv: ERROR: DMA MEM Buffer allocation failed"
Following is the log which comes when the mcsdk video fails:

I can't find the reason for this ! How to solve this problem?
