The Yocto build system can be used to generate a cross-compilation toolchain with a matching sysroot for a target system, as well as a sysroot with native applications. This is referred to as a standard Yocto Project SDK. The Yocto Project can also build an extensible SDK that extends the standard SDK by adding tools to facilitate adding new applications and libraries. This recipe will show how to build both types of SDK.

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.
