请教搞xilinx的高手，关于microblaze的io中断

XIntc gInterruptControllerInst;
XGpio gGpioFieldirqInst;

void Field_IRQ_interrupt(void)
{
        XGpio_Initialize(&gGpioFieldirqInst, XPAR_FIELD_INT_DEVICE_ID);
        XGpio_InterruptDisable(&gGpioFieldirqInst,0xf);
        XGpio_InterruptClear(&gGpioFieldirqInst,0xffff);
        XGpio_InterruptEnable(&gGpioFieldirqInst,0xf);

}

int main()
{
    XGpio_Initialize(&gGpioFieldirqInst, XPAR_FIELD_INT_DEVICE_ID);
    XIntc_Connect(&gInterruptControllerInst,XPAR_INTC_0_GPIO_0_VEC_ID,(XInterruptHandler)Field_IRQ_interrupt,&gGpioFieldirqInst);
    XIntc_MasterEnable(XPAR_INTC_0_GPIO_0_VEC_ID);
    XIntc_Start(&gInterruptControllerInst,XIN_REAL_MODE);
    XIntc_Enable(&gInterruptControllerInst,XPAR_INTC_0_GPIO_0_VEC_ID);
    microblaze_enable_interrupts();
    XGpio_InterruptEnable(&gGpioFieldirqInst,0xf);
    XGpio_InterruptGlobalEnable(&gGpioFieldirqInst);

    while(1);
}

这段代码到  XIntc_Connect(&gInterruptControllerInst,XPAR_INTC_0_GPIO_0_VEC_ID,(XInterruptHandler)Field_IRQ_interrupt,&gGpioFieldirqInst);
注册失败，怎么回事，都调了好几天，饭也吃不好，觉也睡不香的，好痛苦
到底能是哪里出问题了或者谁有好使的代码呢

以前项目留下的一部分代码，定时器中断和GPIO中断。
mhs文件部分是IP核的配置，后面是软件部分。
注释不多，主要看个流程，
整理了一下发上来，希望能有帮助。
编辑备注：MB核采用PLB4.6总线

//      *.mhs文件部分

io 方向设置了吗？  另外GPIO有输入中断和输出中断之分

判断FPGA硬件是否正常，可以去生产一个外围设备测试的代码，
