Embedded Linux Development using Yocto Projects

Key Features

• Optimize your Yocto Project tools to develop efficient Linux-based projects
• Practical approach to learning Linux development using Yocto Project
• Demonstrates concepts in a practical and easy-to-understand way

Book Description

Yocto Project is turning out to be the best integration framework for creating reliable embedded Linux projects. It has the edge over other frameworks because of its features such as less development time and improved reliability and robustness.

Embedded Linux Development using Yocto Project starts with an in-depth explanation of all Yocto Project tools, to help you perform different Linux-based tasks. The book then moves on to in-depth explanations of Poky and BitBake. It also includes some practical use cases for building a Linux subsystem project using Yocto Project tools available for embedded Linux. The book also covers topics such as SDK, recipetool, and others.

By the end of the book, you will have learned how to generate and run an image for real hardware boards and will have gained hands-on experience at building efficient Linux systems using Yocto Project.

What you will learn

• Understand the basic concepts involved in Poky workflows along with configuring and preparing the Poky build environment.
• Configure a build server and customize images using Toaster.
• Generate images and fit packages into created images using BitBake.
• Support the development process by setting up and using Package feeds.
• Debug Yocto Project by configuring Poky.
• Build an image for the BeagleBone Black, RaspberryPi 3, and Wandboard, and boot it from an SD card.

About the Author

Otavio Salvador loves technology and started his free software activities in 1999. In 2002, he founded O.S. Systems, a company focused on embedded system development services and consultancy worldwide, creating and maintaining customized BSPs, and helping companies with their product developments challenges. This resulted in his joining the OpenEmbedded community in 2008, when he became an active contributor to the OpenEmbedded project.

Daiane Angolini has been working with embedded Linux since 2008. She has been working as an application engineer at NXP, acting on internal development, porting custom applications from Android, and on-site customer support for i.MX architectures in areas such as the Linux kernel, u-boot, Android, Yocto Project, and user-space applications. However, it was on the Yocto Project that she found her place.
