    CYUSB3064 add OV9281 no receive data

    yiwei.f_3616931

      1. I add a new sensor  ov9281 that support raw10 mipi data in cyusb3064, but i find CX3 DMA cannot receive mipi data, No access to the CyCx3AppDmaCallback() function.and the mipi end can be measured with data,Why can't receive data?

       

        Below is my mipi configuration.

      /* ov9281_RAW8_720p : 800p */

      CyU3PMipicsiCfg_t ov9281_RAW8_720p = 

      {

          CY_U3P_CSI_DF_RAW8,  /* CyU3PMipicsiDataFormat_t dataFormat */

          2,                          /* uint8_t numDataLanes */

          2, /* uint8_t pllPrd */

          89, /* uint16_t pllFbd */

          CY_U3P_CSI_PLL_FRS_250_500M, /* CyU3PMipicsiPllClkFrs_t pllFrs */ 

          CY_U3P_CSI_PLL_CLK_DIV_4, /* CyU3PMipicsiPllClkDiv_t csiRxClkDiv */

          CY_U3P_CSI_PLL_CLK_DIV_4, /* CyU3PMipicsiPllClkDiv_t parClkDiv */

          0,                 /* uint16_t mClkCtl */

          CY_U3P_CSI_PLL_CLK_DIV_2, /* CyU3PMipicsiPllClkDiv_t mClkRefDiv */

          1280,         /* uint16_t hResolution */

          50                         /* uint16_t fifoDelay */

      };

       

       

       

       

       

      we measured The  G6 and H5  find no signal ,it is looks like  MIPI-CSI2 config  problem?
