When configuring the S32K311 chip's UART, the simple send function requires power cycling through the control board each time it needs to send data correctly. Using the Lpuart_Uart_Ip_AsyncSend function for sending data is preferable.
Hi@ Finnc
Share your project details, and I'll check it for you.
Please tell me the hardware you are using. If it is not an official EVB, please tell me the frequency of your external crystal oscillator.
Hi@ Finnc
I checked the project you provided and tested it; it works fine on my end.
Software version S32DS 3.6.0 RTD 6.0.0, external crystal oscillator 20MHz
