BF706 EPPI image problem

Recently, I was using the EPPI controller to collect image data , image format is 640* 480 , PCLK =24M ,I confirm that the sensor has data to EPPI controller, and the DMA setting is OK. I guess the configuration of EPPI controller is not successful, resulting in no data collection.   here  is my code , thanks ,cEPPI_Image.rarheck it .

    Can you please refer the this Link. There is couple of simple register based EPPI codes to understand how EPPI can be configured. Please take this as reference. Hope this helps.

    Also we suggest you to refer the EPPI Programming Model section(PageNo:1670 / 2223) in the HRM of ADSP-BF70x. This section describe programming techniques, including receiving or transmitting ITU-R 656 frames; configuring transfers in GP0, GP1, GP2, and GP3 modes; and managing EPPI mode configurations. You can find the HRM from below link,
