Hello all,

          I taking the video source from VCR and want to display continuously frame on the monitor.I am able to display one frame on screen and after this the video is instantly disappeared. I found that after one frame there is no interrupt by DMA.So second time there is not able to read in ppi0 driver.One problem is also that after enable the DMA  ,dma config register is not able to enable.As we print the register value. Where should be problem, please help.

                                     -Regards

Sounds like this is a blackfin DMA/interrupt/PPI question, not a Linux one.
