Creating your own custom image for Raspberry Pi

To facilitate a cross-compile environment for Raspberry Pi images, I created an image builder project: build-raspbian-image on GitHub.

This project is based on a blog post and code by Klaus Maria Pfeiffer.

The code functions correctly on Debian (tested with CrunchBangLinux) and Ubuntu.

Instructions:

1. Clone the repository: git clone https://github.com/andrius/build-raspbian-image.git
2. Navigate into the cloned directory. Review the content and install necessary packages, or execute the ./install.sh script.
3. Run ./raspbian/build_raspbian_sd_card.sh. The resulting .img file will be located in the /tmp/rpi folder.

The main challenge currently lies with the cross-compilation environment. Due to time constraints, the process is not fully automated. During cross-compilation, manual intervention is required:

echo "Execute all necessary commands, then type exit"
echo "Asterisk install files are located at /usr/src/asterisk"
bash

Update

The GitHub repository has been updated. The installation script now mounts a delivery folder to the target RPI image and executes an install.sh script located within that mounted folder. This allows for custom build scripts or manual command-line access via bash during RPI image creation.

An example image created with this process, featuring Ruby 2.0 and Asterisk PBX, is available.

Standard Raspberry Pi flashing instructions apply (a good guide can be found at this site describing the flashing procedure):

• Decompress the .gz file.
• Insert the SD card.
• Flash the image using the Linux dd command.
