Hi Muruga, If you would share your schematic with me it would be very helpful. You can either send me a private message on E2E with an attachment or email it to pa_deltasigma_apps@ti.com. My initial impression is that you might need to wait a bit longer before communicating with the ADS1256 . If you are able, I would recommend waiting for a /DRDY interrupt as an indication that the device is powered and actively converting. Also, which o-scope channel is which? These are the 3.3V (DVDD) and 5V (AVDD) supplies, correct?
