Hi,
By default, the SDK examples uses UART to send information to a terminal.
Please, open a terminal with a 115200 baud rate.
You can use any terminal you want, but if you want to open a Terminal in MCUXpresso please go to Window -> Show View -> Other and select Terminal.
Then, click on Open a Terminal.

Configure the terminal.

And you should now be able to see the message.

I hope this helps, Daniel.
