LpuartFlexio_Uart_Ip_Example_S32K344 with interrupt not working

[janakiraman-s]

Hi Team,

I am currently using the LpuartFlexio_Uart_Ip_Example_S32K344 example code. I made some changes to enable simple transmission and reception from UART with interrupt mode. While the transmission is working perfectly, I am facing an issue with the reception side. The callback function gets triggered only once. When I send data a second time, the callback function does not get triggered.

"Could you please assist me in resolving this problem?"

Thanks,

Janakiraman

Hi Janakiraman,

Seems that you forget call Lpuart_Uart_Ip_SetRxBuffer() in LPUART_UART_IP_EVENT_RX_FULL  of rx callback. Please refer to the discussion in: UART_Lpuart_Uart_Ip_AsyncReceive_loss_packet

Best Regards,
Robin
