Debasish,
Everything is working on my DM8148 EVM, when I follow the steps described in the EZSDK software guide.
This is what I have:
root@dm814x-evm:/usr/share/ti/syslink-examples/TI814X/helloworld# ./run.sh
+ ./slaveloader startup DSP server_dsp.xe674
Attached to slave procId 0.
Loading procId 0.
Loaded file server_dsp.xe674 on slave procId 0.
Started slave procId 0.
+ ./app_host DSP
--> App_exec:
App_exec: event received from procId=0
<-- App_exec: 0
+ ./slaveloader shutdown DSP
Stopped slave procId 0.
Unloaded slave procId 0.
Detached from slave procId 0.

Did you change your boot arguments from the default mem=364M@0x80000000 mem=320M@0x9FC00000 to the recommended one mem=169M@0x80000000 ?
Did you perform the below steps before starting the DSP server?
target # /etc/init.d/pvr-init stop
target # /etc/init.d/matrix-gui-e stop
target # /etc/init.d/load-hd-firmware.sh stop
target # modprobe syslink
Best Regards,
Pavel
