DMA1_Channel1_IRQn请教配置

lixglixg

请教下：
  配置DMA中断时
NVIC_InitStructure.NVIC_IRQChannel = DMA1_Channel1_IRQn;//
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;//
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;//
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);//  
以上编译正确，但连接仿真时死到这里，下面配置的另一通道则正常

  NVIC_InitStructure.NVIC_IRQChannel = DMA1_Channel2_IRQn;//
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 3;//
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;//
NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
NVIC_Init(&NVIC_InitStructure);//
以上部分仿真正常，

2通道需要同时打开

请教大神

正点原子
