DCPLBMissWithoutReplacement error for ADSP BF609.


I am working on custom board using BF609, I am able to run POST DDR and SPI test successfully using POST project.
I am using CCES version 2.8.1.
I have integrated POST code of PSI and DDR to my project.But with my custom project I am able to run SPI test but for DDR test I am getting error :

A non-recoverable error or exception has occurred.
Description: A data CPLB miss has occurred without a corresponding CPLB entry.
General Type: RunTimeError
Specific Type: DCPLBMissWithoutReplacement
Error PC: 0xffa070ec

Can anyone help me with this error? Also why POST example is running successfully standalone but with my integrated code it doesn't run.
