66AK2H14: TMS320TCI6638 DDR3 configuration issue

Part Number: 66AK2H14

Hi,

In one of our system board we are observing DDR3 memory configuration issue.

The bootup is stopping at 

"DRAM Configuration: 0"

Where as In the working board we can observe the below output as in the image.

We tried replacing the DDR3 memory IC's also. 

Looks like the SoC is struck while doing the DDR3 memory configuration. but cause of the error is not known.

Kindly advice how do we proceed in debugging the issue.

Best Regards,

Sumathi
