Pa_addMAC fails when integrating with SRIO

Hi,
i am using PA_emacExample project to receive the RAW ethernet packets form the FPGA. I removed Add_IP, Add_port commands. configured Add_mac routing information to pa_dest_HOST  to receive the RAW ethernet packets. it is running successfully all the times with out any problem.
But in the actual scenario i want ethernet and srio to co exist in the same core. when i started integrating SRIO driver (provided by TI) with the above project, i face this Pa_addmac Timeout issue.
“[C66xx_0] Timeout waiting for reply from PA to Pa_addMac command
[C66xx_0] PASS setup failed”

i debugged it and found that problem arises only when i add the SRIO_START() driver API. it is used to configure the RX,TX,Accumulator configuration for SRIO. Since SRIO and ethernet is having different CPPI Instances it should not cause any problem right? But can you suggest why i am getting this issue.

Thanks,
Nachiappan RM.
