Create Personalized Raspberry Pi Operating System Images Using Rpi-image-gen Tool
Getting Started with rpi-image-gen: A Hands-On Guide for Custom Raspberry Pi OS images
The Raspberry Pi community just dropped a new tool, rpi-image-gen, taking custom OS image creation to the next level. Here's a no-nonsense guide to help you get the most out of this versatile tool.
Rpipegen: Essential Tool for Personal Projects & Beyond
To cut through the menial tasks of creating custom Raspberry Pi OS images, rpi-image-gen offers a streamlined approach—perfect for embedded projects, IoT, or any time you need a lightweight solution.
Setting Up rpi-image-gen
Before diving in, make sure you have these prerequisites:
- Install Dependencies
- Have Python 3 and pip installed.
- Clone the official rpi-image-gen repository:
- If a specific tool is mentioned (and not pi-gen), locate its official repository and follow its README for setup.
- Navigate to the Example of Your Choice
- For pi-gen, start with the "slim" or "webkiosk" examples.
- If using the latest tool, look for a suitable example or configuration file in the repo.
Unraveling the "Slim" Configuration
The "slim" configuration produces a minimal OS image with only necessary packages included.
- Configuration Files
- config or stage.rc: Defines build instructions, packages to include or exclude, and the stage name.
- 00-packages: Lists the packages to be installed; slim configurations have a minimal or curated list.
- 00-run.sh: Contains build commands that are executed during the process.
Building Your Slim Image
- Clone the Repository and Navigate
- Review & Customize
- Open the relevant configuration file (e.g., , , or ).
- Check the included packages and scripts. Modify them to fit your exact requirements.
- Build the Image
- Following the tool's documentation, run the build command:
- For , follow the README instructions, which usually involve a build or image generation script.
- Writing the Image to SD Card
- Use a tool like Raspberry Pi Imager or Balena Etcher to flash the generated image to an SD card.
- Insert the SD card into your Raspberry Pi and boot.
Tips for Success
- Customization: Edit the configuration files as needed to add or remove packages.
- Scripts: Learn what each script does in the slim stage so you can fine-tune your image.
- Documentation: Keep the latest README and documentation handy for updates and additional options.
Troubleshooting
- Image Not Booting: Check your configuration matches the target Raspberry Pi model.
- Missing Features: Ensure all essential drivers and kernel modules are included for networking or hardware support.
