• FRDM-MCXA276 board

• Personal Computer

Board settings

No special settings are required.

Prepare the Demo

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

2. Open a serial terminal with the following settings:

   • 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.
