用移植到stm32的ucos写串口中断为什么一直死机啊，研究快两天了，请大侠指点一二。谢谢
中断处理函数
void USART1_IRQHandler(void)
{
OS_CPU_SR cpu_sr;
UCOS_II_REENTRANT_ISR_PROLOG UCOS_II_REENTRANT_ISR_EPILOG
OS_ENTER_CRITICAL();;
OSIntNesting++;
OS_EXIT_CRITICAL();
if(USART_GetITStatus(USART1, USART_IT_RXNE) == SET)
{
data = (USART_ReceiveData(USART1) & 0x7F);
USART_ClearITPendingBit(USART1, USART_IT_RXNE);
}
OSIntExit();
}
