Hi @ferenczyg
Sorry for the misunderstanding.
I am going to use the LpuartFlexio_Uart_Ip_Example_S32K344 code as a reference. When you create this project from example, no changes need to be done to run it in the S32K344-T172EVB and S32K344-Q257EVB, and if you see the project by default use 257package. If you change the package to 172 the following changes are done:


As you can see, the only changes made are some comments, but the pin's configuration does not change. This means that if you create the project for one package should work for the other one.
Just take into consideration the difference in the number of pins.
