Hello Team,
I am using AM5728 board for development.
our hardware is connected AM5728-->GS2971-->Rugged camera
we are able to read data from gs2971 driver and properly getting the data from all the registers, HD video format and pixel format every thing properly getting.
actually i am running below method
