Custom Images, Device CI/CD and Other Boards

10 Lektionen in dieser Stufe

1. Building a Custom Raspberry Pi OS Image with pi-gen
   Generate your own Bookworm-based image from source stages. · Lab: Build a lite image with pi-gen and boot it.
2. Baking Your Application into the Image with a Custom Stage
   Add packages, users, units and configuration at build time. · Lab: Add a stage that installs your service, enables the read-only layout and removes default credentials.
3. Yocto Project Concepts: Layers, Recipes and Board Support
   Understand when a from-source distribution is worth the cost. · Lab: Read a minimal layer and recipe and map each part to its pi-gen equivalent.
4. A CI Pipeline That Lints, Tests and Builds Images
   Automate quality checks and image builds on every change. · Lab: Configure a pipeline with a self-hosted arm64 runner that produces an image artifact.
5. Hardware-in-the-Loop Test Rigs
   Flash, boot and test real boards automatically. · Lab: Build a rig that switches a card, power-cycles a board and checks boot over serial.
6. Versioning, Signing and Publishing Release Artifacts
   Trace every image in the field back to its source. · Lab: Embed version and commit in the image, sign the artifacts and publish checksums.
7. The SBC Landscape: Rockchip, Allwinner and Their Boot Chains
   Compare other board families in boot, kernel support and vendor quality. · Lab: Compare boot stages and kernel sources for a Pi, an Orange Pi and a Radxa ROCK.
8. Running Your Stack on an Orange Pi or Radxa ROCK
   Install a community Debian image and find the equivalent pins and buses. · Lab: Flash a board, enable I2C through its overlay mechanism and read your sensor.
9. A Hardware Abstraction Layer for Board-Agnostic Code
   Isolate board differences behind one small interface. · Lab: Wrap GPIO, I2C and board facts behind a module with per-board back ends using libgpiod.
10. Supply Risk, Second Sources and Board Selection
    Choose and qualify hardware for a multi-year product. · Lab: Score three boards on availability, lifetime guarantee, software support and cost.

Abschlussprojekt

A pipeline that turns a Git tag into a signed, tested image for the Pi, plus the same application running through a hardware abstraction layer on an Orange Pi or Radxa ROCK board.
