Board : MR CAN HUBK344 - EVB
Code: LpuartFlexio_Uart_Ip_Example_S32K344 

S32 DS platform 3.5.14
Hi, 
I am trying to communicate using LPUART2, but I haven't been successful. I have changed the configuration of UART and Intctrl_Ip according to LPUART2 with help of schematic. I connected it to the 'Debug Interface' using the X-DCD-LZ adapter. An image of the X-DCD-LZ adapter and the schematic of the 'Debug Interface' connection are also attached. I would like to understand what might be going wrong.

Thanks!

Hi

Are the highlighted configurations in the picture the ones you modified?

Lpuart_Uart LPUART_2.pngIntCtrl_Ip LPUART2_IRQn.png

Are PTA8(LPUART2_RX) and PTA9(LPUART2_TX) configured in Pins Tool?
After calling Lpuart_Uart_Ip_AsyncSend, can the logic analyzer or oscilloscope observe the UART signals at PTA9?

If it still doesn't work, I suggest you upload a simplified test project for me to check.

Best Regards,
Robin
