stm32 rtc和串口中断之间的冲突问题

wssc0000

我rtc中断有部分代码，导致串口通讯有时候会发生接收不完整的情况
比如我发送123456,10次大概就有1-2次出现只收到1的情况。发现是rtc和串口中断冲突。如果我将rtc中的内容删掉，就不会出现串口接收内容不全的情况、
改中断优先级也没有办法。请大神指点下。

[mw_shl_code=c,true]void NVIC_Configuration(void)
{  
    NVIC_InitTypeDef NVIC_InitStructure;

  /* Configure the NVIC Preemption Priority Bits */  
  NVIC_PriorityGroupConfig(NVIC_PriorityGroup_1);
  
  /* Enable the USARTz Interrupt */
  NVIC_InitStructure.NVIC_IRQChannel = USARTz_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);

  NVIC_InitStructure.NVIC_IRQChannel = USARTx_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);

        NVIC_InitStructure.NVIC_IRQChannel = USARTy_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
       
       
//  /* Enable the RTC Interrupt */
  NVIC_InitStructure.NVIC_IRQChannel = RTC_IRQn;
  NVIC_InitStructure.NVIC_IRQChannelPreemptionPriority = 1;
  NVIC_InitStructure.NVIC_IRQChannelSubPriority = 0;
  NVIC_InitStructure.NVIC_IRQChannelCmd = ENABLE;
  NVIC_Init(&NVIC_InitStructure);
