Hi,

I tried uart_pal_echo example from SDK 3.0.3 on DEVKIT revE and it seems to be working fine, as per example description in doxygen file.

Hmmmmm

while trying the example uart echo in matlab i had to change from serial 1 to serial 0 in config box to get it working

should i change it also when i use the example in SDK in s32 ?

Hi,

on DEVKIT-MPC5744P revE LINFlexD_0 using pins PB2/PB3 is connected to K20 MCU which serves as serial-to-USB module on the board. So LINFlexD_0 need to be selected in uart_pal component and PB2/PB3 pins configured in pin_mux component. But it is done in demo code.
