STM32F746 Camera Interfacing using ADV7180

I am working on custom board, based on STM32F746 .

LCD Is working fine. And Configured the ADV7180 sing I2C. I have configured the DCMI with Continues Mode to display video on LCD.

All interrupts are working fine. (Vsync, Frame and Line)

I'm getting data from D0-D7 pins of the DCMI Port ( 8 - Bit Data ).

But DCMI_DR register always zero.

Any help is appreciated.
