tl-messageq-gpmc-edma

1.在tl-messageq-gpmc-edma例程中，改写了main_host.c文件，如下：
/*
*  ======== Main_main ========
*/
Int Main_main(Void)
{
    UInt16      remoteProcId;
    Int         status = 0;
    Int         i;
    Int         FPAG_DATA_SIZE = 0;

    printf("--> Main_main:\n");

    remoteProcId = MultiProc_getId(Main_remoteProcName);

    /* application create phase */
    status = App_create(remoteProcId);

    if(status < 0) goto leave;

    /* application execute phase */
    //status = App_exec();
    for(i = 0; i < 6; i++)
{
    status = App_exec(FPAG_DATA_SIZE);

    if(status < 0) goto leave;

    printf("FPAG_DATA_SIZE = %x, i = %d\n",FPAG_DATA_SIZE, i);

    FPAG_DATA_SIZE = FPAG_DATA_SIZE + 8 * 0x1000;

    printf("FPAG_DATA_SIZE = %x, i = %d\n",FPAG_DATA_SIZE, i);
}

    /* application delete phase */
    status = App_delete();

    if(status < 0) goto leave;
       
leave:
    printf("<-- Main_main:\n");

    status = (status >= 0 ? 0 : status);
    return (status);
}

在这个循环中，App_create执行1次，App_exec执行6次，App_delete执行1次，在执行./app_host DSP1时出现以下问题，就是App_exec只执行了1次，第二次时卡在了App_exec: message received, sending message 16，现象如下：

这是什么原因呢？是因为没有起中断吗？中断这块在哪看呢？怎么确定中断没有起？或者怎么控制起中断呢？

您好，
   您可以查看GPIO_IRQSTATUS_RAW_0寄存器，并读取其值。

您好，
     这个截图是哪个文件里的？
