TMS320C6455 CSL中断

程序本来是用来进行SRIO doorbell中断的，但是接收到doorbell信息后，程序没有进入相应的中断，调试的时候写了一个直接触发映射到的INT4程序，发现该程序确实无法进入相应的中断，请求协助~。不知道是不是CSL_intcPlugEventHandler这一块出了问题，调试的时候，触发中断之后，程序就跑飞了。还有请问CSL_IntcContext intcContext; 这个参数的意义，以及后面数值的设置有没有什么道理。看了一些设置好像都是自己想怎么弄怎么弄的。

void main(void)
{
volatile int i;

int *ptrRcvData;

InitPLL1();
EnablePeripheral(); // 打开SRIO等外设
initInt();

ptrRcvData = (int *)DSP1_SRIO_RCV_ADDR;
for(i=0; i<(DSP1_SRIO_DATA_BYTES/4); i++)
{
*(ptrRcvData + i) = 0; // 清空内存空间
}

//void InitSRIO(unsigned int srio_source_id,unsigned int portCfg)
// portCfg=14: 1p4x
// portCfg=41: 4p1x
//InitSRIO_1(0x006f0001,41); //初始化SRIO
DSP1InitSRIO(0x00000001,41); //初始化SRIO
