Hardware requirements

• Type-C USB cable

• FRDM-MCXL255 board

• Personal Computer

Board settings

Connect a external voltage source to the J2-7.

Prepare the Demo

Note: MCUXpresso IDE project default debug console is semihost

1. Connect a Type-C USB cable between the host PC and the MCU-Link port(J16) on the target board.

2. Open a serial terminal with the following settings (See Appendix A in Getting started guide for description how to determine serial port number):

   • 115200 baud rate

   • 8 data bits

   • No parity

   • One stop bit

   • No flow control

3. Download the program to the target board.

4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

The log below shows the output of the hello world demo in the terminal window:
