Announcement
meta-raspberrypi - Yocto/OE BSP Layer for Raspberry Pi
Official Yocto Project and OpenEmbedded Board Support Package (BSP) layer for various Raspberry Pi boards, enabling developers to build custom embedded Linux distributions.
Project Introduction
Summary
meta-raspberrypi is the official OpenEmbedded layer providing board support for Raspberry Pi devices (including Pi 0/1/2/3/4/5 and CMs). It contains all the necessary recipes and configurations to build bootable Linux images for these platforms.
Problem Solved
Building a custom embedded Linux distribution for Raspberry Pi boards using the Yocto Project or OpenEmbedded requires board-specific metadata, kernel configurations, and drivers. This layer provides all necessary components to simplify and enable this process.
Core Features
Comprehensive Hardware Support
Includes recipes for the Raspberry Pi kernel, firmware, and bootloader (vchigd/start.elf).
Peripheral Integration
Provides configurations and recipes to support specific Raspberry Pi peripherals like camera modules and displays.
Tech Stack
使用场景
The meta-raspberrypi layer is essential for any project requiring a custom-built embedded Linux operating system for Raspberry Pi boards using the OpenEmbedded build system.
Scenario 1: Industrial IoT Gateway
Details
Building a headless, secure minimal Linux image for an industrial control system or IoT gateway device using a Raspberry Pi Compute Module.
User Value
Allows creating a production-ready, minimal OS tailored specifically for the target hardware and application, reducing attack surface and resource usage.
Scenario 2: Custom Kiosk System
Details
Creating a custom kiosk or digital signage solution based on a Raspberry Pi 4, requiring specific display drivers and application integration into the OS image.
User Value
Enables the inclusion of necessary hardware drivers and direct integration of the application into the OS image, simplifying deployment and management.
