The driver changes UartState->ReceiveStatus to LPUART_UART_IP_STATUS_RX_OVERRUN if the flag OR = 1 in the STAT register.Refer to Lpuart_Uart_Ip_ErrIrqHandler() in Lpuart_Uart_Ip.cThis flag is set when STAT[RDRF] = 1, and the driver fails to read the data bef...
I tried to use S23K312 for Ip Lin debugging with Baby Lin II. Whether I use slave mode or master mode, I get LPUART_LIN_IP_RX_OVERRUN_ERROR, and even LPUART_LIN_IP_FRAME_ERROR and LPUART_LIN_IP_PID_ERROR. I also tried to change the bit rate, such as 19200 ...

通过在STM32F103上测试,默认是开启了过载检测,由软件序列将其清零(先读USART_SR,然后读USART_CR)。 如果有OverrunDisable开关,在不使用HAL库的中断回调来实现串口接收时最好禁止Overrun,不然出现串口接收溢出,移位寄存器中的数据会被覆盖,RDR寄存器中的值将不会改变,也就读不到新数据了。
