How to run RT-Thread on MCUXpressoIDE

This application note describes how to run RT-Thread with MCXUPressoIDE on FRDM-MCXC444.

RT-Thread officially supports only IAR and Keil IDEs by default. This application note describes how to port RT-Thread to NXP's MCUXpressoIDE. While the process is straightforward, it requires careful attention to build configurations and architecture-specific details.

Please refer to ANxxxxx for complete instructions on how to use this software.

1. Software

The development environment of example code is development on:

• MCUXpresso IDE v24.9 [Build 25] [2024-09-26]
• SDK_2_16_000_FRDM-MCXC444
• RT-Thread: V5.2.0

2. Hardware

• FRDM-MCXC444 Development Board

• USB cable
• Personal Computer

3. Setup

Before getting started, you should:

• Be familiar with basic operations, such as downloading and debugging introductory examples like HelloWorld or led_blinky using the MCUX SDK. For more details, refer to: Getting Started with FRDM-MCXC444
• Understand the basic usage of RT-Thread. For more information, refer to: RT-Thread GitHub Repository

You can import this example code just like any other SDK example. The compilation and hardware download process is identical to the HelloWorld example in the SDK.

4. Results

• After downloading the code to the board, connect the serial port and press the reset button.
• Open serial terminal (115200-8-N-1), The following output will be displayed (115200 baud rate):

This indicates that RT-Thread is successfully running on the FRDM-MCXC444. The Finsh command-line interface is enabled by default. You can type "help" and press Enter to display available commands in the terminal.
