QMSS调试出现的问题

HI, 最近在调试6678 的QMSS，出现以下的问题：如果直接导入D:\ti\pdk_C6678_1_0_0_17\packages\ti\drv\exampleProjects\qmInfraExampleProject下的工程，运行正常。但是如果我自己新建一个C66x的工程，将所有源文件拷入该工程，结果运行到result = Qmss_insertMemoryRegion (&hostMemInfo)语句时，总是出现如下错误：Error Core 0 : Inserting memory region 0 error code : -131。经过查询相关文件得知：-131的意思是QMSS LLD queue open error。请问为什么会出现这种错误，谢谢！

    Hi wayne,

                从现象上看，是申请硬件队列失败，相关驱动函数为Qmss_internalQueueOpen（）， 建议对照这个函数的源码查一下对应的队列变量设置是否合理：

    static Qmss_QueueHnd Qmss_internalQueueOpen (Qmss_QueueType queType, int queNum, uint8_t *isAllocated)

    {

       uint32_t      index, startQueue, endQueue;

       *isAllocated = 0;

       if (queNum >= 0)

       {

           /* Invalidate queueFree Object */

           Qmss_osalBeginMemAccess ((void *) &queueFree[queNum], 128);

           queueFree[queNum]++;

           /* Writeback queueFree Object */

           Qmss_osalEndMemAccess ((void *) &queueFree[queNum], 128);

           *isAllocated = queueFree[queNum];

           return (Qmss_QueueHnd) queNum;

       }

       /* Get the range to allocate from */

       startQueue = qmssLObj.maxQueueNum[queType].startIndex;

       endQueue = qmssLObj.maxQueueNum[queType].startIndex + qmssLObj.maxQueueNum[queType].maxNum;

       /* Invalidate queueFree Object */

       Qmss_osalBeginMemAccess ((void *) &queueFree[startQueue], qmssLObj.maxQueueNum[queType].maxNum);

       for (index = startQueue; index < endQueue; index++)

       {

           if (queueFree[index] == 0)

           {

               queueFree[index]++;

               /* Writeback queueFree Object */

               Qmss_osalEndMemAccess ((void *) &queueFree[index], 128);

               *isAllocated = queueFree[index];

               return (Qmss_QueueHnd) index;

           }

       }

       return (Qmss_QueueHnd) -1;

    }
