• Build your own Orange Pi OS image with orangepi-build (non-interactive, for many devices)procedure · unverified · orangepi-build compiles U-Boot, the kernel, a root filesystem or a complete flashable image for Allwinner, Rockchip and RISC-V Orange Pi boards. It runs on an Ubuntu 22.04 host, and every menu choice can be passed as KEY=value on the command line for reproducible builds.
• Building your own Raspberry Pi OS image for a device fleet: rpi-image-gen and pi-gen-microrecommendation · unverified · Instead of hand-configuring each SD card, build a reproducible image from declarative config. rpi-image-gen builds customised images from Raspberry Pi OS packages (with SBOM/CVE reports and secure-boot integration); pi-gen-micro builds tiny embedded systems.
• Identify a Raspberry Pi in code: serial number for the device ID, device tree for the modelprocedure · unverified · For fleet IDs, read the board's unique serial number instead of relying on hostname, IP or MAC. For model detection, use /proc/device-tree/compatible or the board-type field of the revision code, never the 'Hardware: BCM2835' line or a list of exact revision codes.
• Raspberry Pi 4/5 bootloader EEPROM updates: automatic service, release channels, FREEZE_VERSION and A/B updatesprocedure · unverified · On Pi 4/5-class devices the bootloader lives in an EEPROM that rpi-eeprom-update updates automatically at startup. Know how updates are staged, how to pin a version for a fleet, and which update paths survive a power loss.
