I just add a sentence: XGpioPs_IntrDisablePin(pGpioPs,50)and it works!

Now a screen shot for memory!

    XGpioPs* pGpioPs=(XGpioPs*)CallBackRef;    XGpioPs_IntrDisablePin(pGpioPs,50);    xil_printf("Gpio Handler...\n");    XGpioPs_IntrEnablePin(pGpioPs,50);

But I just commented the sentence and re-build the application, it runs either! I don't know why?

and i have noticed that although i just press BTN8 once ,but it prints "Gpio Handler..." 2 times!

The interrupt remains undetected if:

XScuGic_SetPriorityTriggerType(&ScuGic,52,0xFF,0x01);

But it remains interrupt detected if:

1
XScuGic_SetPriorityTriggerType(&ScuGic,52,0xa0,0x03);

The total application is shown as follows:

static void GpioHandler(void*CallBackRef,intBank, u32 Status) {     xil_printf("Gpio Handler...\n"); } int main() {     u32 data;     XGpioPs Gpio;     XGpioPs_Config *ConfigPtr;     ConfigPtr = XGpioPs_LookupConfig(0);     XGpioPs_CfgInitialize(&Gpio, ConfigPtr, ConfigPtr->BaseAddr);        XGpioPs_SetDirectionPin(&Gpio,50,0x0);     XGpioPs_SetOutputEnablePin(&Gpio,50,0x1);        XGpioPs_SetIntrTypePin(&Gpio,50,XGPIOPS_IRQ_TYPE_EDGE_FALLING);     XGpioPs_SetCallbackHandler(&Gpio, (void*)&Gpio, GpioHandler);     XGpioPs_IntrEnablePin(&Gpio,50);        XScuGic ScuGic;     XScuGic_Config* pScuGicCfg;     pScuGicCfg=XScuGic_LookupConfig(XPAR_SCUGIC_SINGLE_DEVICE_ID);     XScuGic_CfgInitialize(&ScuGic,pScuGicCfg,pScuGicCfg->CpuBaseAddress);     XScuGic_Connect(&ScuGic, 52,                     (Xil_ExceptionHandler)XGpioPs_IntrHandler,                     (void*)&Gpio);     XScuGic_SetPriorityTriggerType(&ScuGic,52,0xA0,0x01);     XScuGic_Enable(&ScuGic,52);        Xil_ExceptionInit();     Xil_ExceptionRegisterHandler(XIL_EXCEPTION_ID_INT,(Xil_ExceptionHandler)XScuGic_InterruptHandler,&ScuGic);     Xil_ExceptionEnable();        xil_printf("Intr test: \n");        while(1)    {     }    }

I notify that the XGpioPs_GetPinNumber remains go wrong at the pin 50; it says pin 50 belongs to bank 0.

I don't know why?
