Beskrivning

Build Complete Embedded Linux Systems Quickly and Reliably

Developers are increasingly integrating Linux into their embedded systems: It supports virtually all hardware architectures and many peripherals, scales well, offers full source code, and requires no royalties. The Yocto Project makes it much easier to customize Linux for embedded systems. If you’re a developer with working knowledge of Linux, Embedded Linux Systems with the Yocto ProjectTM will help you make the most of it.

An indispensable companion to the official documentation, this guide starts by offering a solid grounding in the embedded Linux landscape and the challenges of creating custom distributions for embedded systems. You’ll master the Yocto Project’s toolbox hands-on, by working through the entire development lifecycle with a variety of real-life examples that you can incorporate into your own projects.

Author Rudolf Streif offers deep insight into Yocto Project’s build system and engine, and addresses advanced topics ranging from board support to compliance management.

You’ll learn how to

Overcome key challenges of creating custom embedded distributions
Jumpstart and iterate OS stack builds with the OpenEmbedded Build System
Master build workflow, architecture, and the BitBake Build Engine
Quickly troubleshoot build problems
Customize new distros with built-in blueprints or from scratch
Use BitBake recipes to create new software packages
Build kernels, set configurations, and apply patches
Support diverse CPU architectures and systems
Create Board Support Packages (BSP) for hardware-specific adaptations
Provide Application Development Toolkits (ADT) for round-trip development
Remotely run and debug applications on actual hardware targets
Ensure open-source license compliance
Scale team-based projects with Toaster, Build History, Source Mirrors, and Autobuilder
