Hello @PavanKaruchola1 ,
As shown in the below figure, the camera module is connected to the DCMI through the following signal types:
• DCMI clock and data signals
• I2C configuration signals

For that, it is necessary to refer to the Camera module and to the board Schematics and MCU datasheet and check the required pins for this connection.
To find the required pins used to connect B-CAMS-OMV module with an MCU you can refer to UM2779.
This connection made with CN2 connector as shown in the below table.

To find the required pins used to connect STM32H743 with an camera module, I advise you to refer to the datasheet and search the pins of DCMI clock and data signals and I2C configuration signals.
Also you can find the pins connection of Nucleo-H743ZI2 with an camera module by using STM32CubeMX, choose Nucleo-H743ZI2 then enable DCMI.


I hope this help you!
Thank you.
