I2c error while initializing Ov3640 camera interface inside U-boot

Other Parts Discussed in Thread: AM3703

Hi Friends,

I am  trying to test camera interface inside U-boot, Iam using Am3703 configured board.

In  my board I2c3 is used to interface with OV3640. Since the camera  needs  2 byte addressing, when i try to read Product ID, it gives me IO error.

Please suggest how to send 2 byte addressing through I2c inside U-boot. Even I have tried some patches, but the issue remains.

Thanks  & Regards
