@jiri_kral sorry for so many questions, I'm really new to the S32D IDE.
I want to try using the UART port instead since for the printf, because I want to send messages over UART for my project. I have a USB serial on my board, I want to try the [S32K1 AUTOSAR 4.4 RTD 1.0.1 D2202 Example Projects] example name is [Uart_Example_S32K144]. But so far I have some issues with the Port_ci_Port_lp_Cfg files. I can't change the PIN based on my board. I want to use Pin PTC6 as RX and Pin PTC7 as Tx. But I'm having problems as shown below..How can I change the pins? or what am I missing?
Which of the following headers can I use to configure the Pins
