We are working on ADV7180 evaluation board EVAL-ADV7180-32EBZ .

We are facing some issues regarding registers write through I2C Programming instead of using script.


When am writing register 0x6B address(cp output selection 26 register) with value 0xC0 in my programming is being set to 0x00 and video data does not come on LCD.


But when we write 0x6B register to 0xC0  through script file after reading all registers, Data appears on the LCD.

Is any other register making it to '0'.


One more thing is , Do we need to provide any delay between each register write?


Please provide suggestions on this 


Thanks and Regards
