    CX3 with OV2775 Raw12 Transmitting but having problems with two vertical bars in the image

    y-paredesacuna_2439691

      I have an OV2775 Sensor with 1928x1088 RAW12 30 fps Configuration. According to the script the Horizontal Blanking is 1622px and Vertical Blanking 38 px, PCLK 75MHz The MIPI CLK Period is 125 Mhz, THS Prepare 48ns and THS Zero 69 ns. I am using this configuration in the CX3:

              CY_U3P_CSI_DF_RAW12,  /* CyU3PMipicsiDataFormat_t dataFormat */

              4,                          /* uint8_t numDataLanes */

              2,                /* uint8_t pllPrd */

              95,            /* uint16_t pllFbd */

              CY_U3P_CSI_PLL_FRS_500_1000M, /* CyU3PMipicsiPllClkFrs_t pllFrs */

              CY_U3P_CSI_PLL_CLK_DIV_8,    /* CyU3PMipicsiPllClkDiv_t csiRxClkDiv */

              CY_U3P_CSI_PLL_CLK_DIV_8,    /* CyU3PMipicsiPllClkDiv_t parClkDiv */

              0,                        /* uint16_t mClkCtl */

              CY_U3P_CSI_PLL_CLK_DIV_2,    /* CyU3PMipicsiPllClkDiv_t mClkRefDiv */

              1928,                /* uint16_t hResolution */

              150                            /* uint16_t fifoDelay */

      I have tried to change the parameters and this is the best result I have got so far. However I still get two big vertical strips in top of my image when I stream it:

       

      Any help will be largely appreciated thank you!
