Hi Nimish I suspect your problem is related to the KATADC I2C contoller for ROACH2. I had to modified it to work with the EPB 32bit bus and related byte enables access a while ago. Just check the your KAT_ADC_IIC_CONTROLLER pcore against the in the SKA-SA repo. This might explain why your ADC is not getting properly set up.
