UART issue in K388

I am working on S32 Design Studio Version 3.5, using RTD version 5.0.0 for S32K388 board. My objective is to execute an example of UART provided by the mentioned RTD package, I am able to build this example project but when I try to debug the same using Trace32 I am not getting print messages in my Serial Terminal (I am using Tera Term for this purpose). The onboard UART does not work in S32K388, so I am using external connections for TX (PTA 3) and RX (PTA 2) pins which are connected to J695 pin set of the board. Looking for a solution to this issue 
Thanks in advance.

Hi @nxg12018,

I assume you are using "LpuartFlexio_Uart_Ip_Example_S32K388". If not, just confirm the pins are correctly configured and initialized. Also, check if the baud rate is correctly set between the MCU and the uart module as well.

Best regards,
Julián
