RDK4 Hello World

Rutronik Development Kit 4 Programmable System-on-Chip CY8C4149AZE-S598 "Hello World" Code Example.

This example is an introduction to the basic components of the board: LEDs, User Button 1 and KitProg3 UART for debugging.

Requirements

• ModusToolbox™ software 2025.4.0
• The latest hardware release RDK4 Rev2.

Supported toolchains (make variable 'TOOLCHAIN')

• GNU Arm® Embedded Compiler v11.3.1 (GCC_ARM) - Default value of TOOLCHAIN

Using the code example

Create the project and open it using one of the following:

In Eclipse IDE for ModusToolbox™ software

1. Click the New Application link in the Quick Panel (or, use File > New > ModusToolbox™ Application). This launches the Project Creator tool.

2. Pick a kit supported by the code example from the list shown in the Project Creator - Choose Board Support Package (BSP) dialogue.

   When you select a supported kit, the example is reconfigured automatically to work with the kit. To work with a different supported kit later, use the Library Manager to choose the BSP for the supported kit. You can use the Library Manager to select or update the BSP and firmware libraries used in this application. To access the Library Manager, click the link from the Quick Panel.

   You can also just start the application creation process again and select a different kit.

   If you want to use the application for a kit not listed here, you may need to update the source files. If the kit does not have the required resources, the application may not work.

3. In the Project Creator - Select Application dialogue, choose the example by enabling the checkbox.

4. (Optional) Change the suggested New Application Name.

5. The Application(s) Root Path defaults to the Eclipse workspace which is usually the desired location for the application. If you want to store the application in a different location, you can change the Application(s) Root Path value. Applications that share libraries should be in the same root path.

6. Click Create to complete the application creation process.

For more details, see the Eclipse IDE for ModusToolbox™ software user guide (locally available at {ModusToolbox™ software install directory}/docs_{version}/mt_ide_user_guide.pdf).

Operation

The firmware example uses KitProg3 Debug UART for debug output. A Blue LED or Red LED is selected to blink once per second as a button USER_BTN1 is pressed once. Also LEDs are changed if any key code is sent to the terminal. Use your preferred terminal software to track the debug output or simply load a ModusToolbox™ native "Terminal" tool.

Debugging

If you successfully have imported the example, the debug configurations are already prepared to use with the KitProg3 or MiniProg4. Open the ModusToolbox™ perspective and find the Quick Panel. Click on the desired debug launch configuration and wait for the programming to complete and the debugging process to start.

SBC Development Mode

A special mode, called SBC Development Mode, is available during software development or debugging of the system. The watchdog counter is stopped and does not need to be triggered. This mode can be accessed by setting the TEST [FO3] pin to GND during SBC Init Mode.

Legal Disclaimer

The evaluation board including the software is for testing purposes only and, because it has limited functions and limited resilience, is not suitable for permanent use under real conditions. If the evaluation board is nevertheless used under real conditions, this is done at one’s responsibility; any liability of Rutronik is insofar excluded.
