Hi,
I tested both examples and it works, I can receive bytes sent from PC.
Just for uart_pal_mpc5748g example, PC terminal must be set to send endline upon enter as mentioned in example doxygen file.
For linflexd_uart_echo_mpc5748g example I just increase timeout value in ReceiveData Blocking function so I was able to write Hello from terminal in time.
BR, Petr
