System_linkCreate problems with ipnc rdk 3.5

aa aa1

i am using ipnc rdk 3.5 with mcfw. i am going to write a app that will take input from local file and do some analysis on dsp with link api. so i write a standlone app. when i run this app,

"System_linkCreate(ipcBitsOutHostId, &ipcBitsOutHostPrm, sizeof(ipcBitsOutHostPrm));" is successful

but

" System_linkCreate(ipcBitsInDspId, &ipcBitsInDspPrm, sizeof(ipcBitsInDspPrm));" is failed with on response

any one can give me some help? thanks a lot!

the main part of code is as below:

        IpcBitsOutLinkHLOS_CreateParams   ipcBitsOutHostPrm;
        UInt32 ipcBitsOutHostId = SYSTEM_HOST_LINK_ID_IPC_BITS_OUT_0;
        UInt32 ipcBitsInDspId = SYSTEM_DSP_LINK_ID_IPC_IN_0;

        ipcBitsOutHostPrm.baseCreateParams.outQueParams[0].nextLink = ipcBitsInDspId;
        ipcBitsOutHostPrm.baseCreateParams.notifyNextLink = FALSE;
        ipcBitsOutHostPrm.baseCreateParams.notifyPrevLink = FALSE;
        ipcBitsOutHostPrm.baseCreateParams.noNotifyMode = TRUE;
        ipcBitsOutHostPrm.baseCreateParams.numOutQue = 1;
        ipcBitsOutHostPrm.inQueInfo.numCh = 1;

        OSA_printf("in dsp test 2\n");
        IpcBitsInLinkRTOS_CreateParams   ipcBitsInDspPrm;
        UInt32 helloWorldDspId          = SYSTEM_LINK_ID_HELLOWORLD_0;
        ipcBitsInDspPrm.baseCreateParams.inQueParams.prevLinkId    = ipcBitsOutHostId;
        ipcBitsInDspPrm.baseCreateParams.inQueParams.prevLinkQueId = 0;
        ipcBitsInDspPrm.baseCreateParams.outQueParams[0].nextLink = helloWorldDspId;
        ipcBitsInDspPrm.baseCreateParams.noNotifyMode              = TRUE;
        ipcBitsInDspPrm.baseCreateParams.notifyNextLink            = TRUE;
        ipcBitsInDspPrm.baseCreateParams.notifyPrevLink            = FALSE;
        ipcBitsInDspPrm.baseCreateParams.numOutQue                 = 1;

        HelloWorldLink_CreateParams helloPrm;
        helloPrm.inQueParams.prevLinkId = ipcBitsOutHostId;
        helloPrm.inQueParams.prevLinkQueId = 0;
        helloPrm.outQueParams.nextLink = SYSTEM_LINK_ID_INVALID;

        OSA_printf("in dsp test 3 ipcBitsOutHostId %x\n", ipcBitsOutHostId);
        System_linkCreate(ipcBitsOutHostId, &ipcBitsOutHostPrm, sizeof(ipcBitsOutHostPrm));
        OSA_printf("in dsp test 4\n");
        System_linkCreate(ipcBitsInDspId, &ipcBitsInDspPrm, sizeof(ipcBitsInDspPrm));
        OSA_printf("in dsp test 5\n");
        System_linkCreate(helloWorldDspId, &helloPrm, sizeof(helloPrm));
