没有发问题就发了   用原子哥的例程  移植到STM32L15系列的UCOS系统  开始一切正常 在初始化的时候加入外部中断初始化后进入不了任务了

程序死在了startup_stm32f10x_md.s 文件

EXTI15_10_IRQHandler
RTC_Alarm_IRQHandler
USB_FS_WKUP_IRQHandler
TIM6_IRQHandler
TIM7_IRQHandler

                B       .

                ENDP

                ALIGN


的B这个位子

开启了外部中断，有没有写中断处理函数？

        NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
        EXTI_ClearITPendingBit(ChargingRX1Line);
        NVIC_InitStructure.NVIC_IRQChannel = ChargingRX1LineIR;
        NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
        NVIC_InitStructure.NVIC_IRQChannelSubPriority = 5;
        NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
        NVIC_Init(&NVIC_InitStructure);
  

把这段屏蔽掉就行了

NVIC_PriorityGroupConfig(NVIC_PriorityGroup_0);
        EXTI_ClearITPendingBit(ChargingRX ...

什么原因哦
