STM32 EXTI求各位指导啊

DMA2_Channel4_5_IRQHandler
                B       .//指针老指在这个位置
                ENDP
                ALIGN

有这段内容的时候出现上述情况，而且中断一直进不去，求高手指引个方向
GPIO_EXTILineConfig(GPIO_PortSourceGPIOA, GPIO_PinSource11);        
EXTI_InitStructure.EXTI_Line = EXTI_Line11;
EXTI_InitStructure.EXTI_Mode = EXTI_Mode_Interrupt;               
EXTI_InitStructure.EXTI_Trigger = EXTI_Trigger_Falling;   
EXTI_InitStructure.EXTI_LineCmd = ENABLE;
EXTI_Init(&EXTI_InitStructure);

PA11脚不接入信号时都是可以运行的，接入后程序死了，停留在上述位置，请各位给个指导性建议，谢谢！

没有中断服务函数。

回复【2楼】正点原子:
---------------------------------
中断服务函数是指这个的么？
void EXTI15_10_IRQHander(void)
{
if(EXTI_GetITStatus(EXTI_Line11) != RESET)
{
EXTI_ClearITPendingBit(EXTI_Line11);
             }
}
程序运行时没进中断。。。

你的中断函数入口 要跟 启动文件的对应上。 

否则进不了中断的

void EXTI15_10_IRQHander(void) 

EXTI15_10_IRQHandler

你看出名字有个区别了吧 。

呵呵 多细心点就好了

哈哈   我也是这个问题，我把TIM2_IRQHandler的2写成3了。。。。
