Hi ,

      The problem is that we have fabricated and assembled 4 PCB, of which 3 are working fine in the 4th one I'm facing this issue, kindly guide me in debugging or what critical points that should be checked.

Hi SUHAS_KRISHNA ,

 

Please help to verify the DDR component with EMIF example design on the failure board.

Gather the calibration report and share it here for more details.

      Hi SUHAS_KRISHNA ,

       

      Have you tested the EMIF example design on the board to verify the calibration status of the DDR ?

       

      Regards,
