TDA2SX: The pvrsrvinit process failed to run

Part Number: TDA2SX

We want to run the application under /dlsdk and get the following error prints when the application is launched:

PVR:(Warning): LoadWSModule: Window system module libpvrws_KMS.so did not validate native display [98, /generic_ws.c]
PVR:(Warning): LoadWSModule: Window system module libpvrws_WAYLAND.so did not validate native display [98, /generic_ws.c]
PVR:(Error): Couldn't load WS module libpvrws_OMAPDRI2.so [44, /generic_ws.c]

Then we found out that probably because pvrsrvinit failed to execute,we run it and get the following error prints:

:/opt/glsdk# pvrsrvinit
PVR:(Error): SrvInit: PVRSRVInitSrvConnect failed (129) [37, /srvinit.c]
PVR:(Error): main: SrvInit failed (129) [47, /pvrsrvinit.c

So, how do we solve this problem?
