Hi Nishant,
Welcome to the TI E2E Forums!
You're jumper setting look correct. I also recommend checking:
- Pin 6 on U11. Make sure it is HIGH to allow the on-board clock connection to the ADS1282. (This is normally controlled by the MMB0).
- Also check that the /RESET signal on the ADS1282 is HIGH. (Controlled by PCA9535).
Best Regards,
Chris
