Embedded Linux Development Using Yocto Project Cookbook - Second Edition

By: Alex Gonzalez

Overview of this book

The Yocto Project has become the de facto distribution build framework for reliable and robust embedded systems with a reduced time to market.You'll get started by working on a build system where you set up Yocto, create a build directory, and learn how to debug it. Then, you'll explore everything about the BSP layer, from creating a custom layer to debugging device tree issues. In addition to this, you’ll learn how to add a new software layer, packages, data, scripts, and configuration files to your system. You will then cover topics based on application development, such as using the Software Development Kit and how to use the Yocto project in various development environments. Toward the end, you will learn how to debug, trace, and profile a running system. This second edition has been updated to include new content based on the latest Yocto release.

Dedicated applications are what define an embedded product and Yocto offers helpful application development tools, as well as the functionality to integrate with popular Integrated Development Environments (IDE) such as Eclipse and Qt Creator. It also provides a wide range of utility classes to help in the integration of finished applications into the build system and target images. A normal embedded Linux software development team is logically divided into the following roles:

  • BSP developers in charge of the Board Support Package, which is the bootloader and Linux kernel. This team has the greatest exposure to the hardware. As we have seen in Chapter 2, The BSP layer, BSP development uses primarily the Yocto SDK.
  • Application developers will work on the Linux user space applications that define the product, including user interfaces. Developing applications for embedded Linux is not that different from developing applications for a Linux server or desktop, as the kernel abstracts...
