Overview of this book

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.

Diving into BitBake Metadata

Utilizing a development shell


When editing packages or debugging build failures, a development shell can be a useful tool. When we use devshell, source files are extracted into the working directory, patches are applied, a new terminal is opened, and files are placed in the working directory.

In the new terminal, all the environment variables needed for the build are still defined, so we can use commands such as configure and make. The commands execute just as if the build system was executing them.

The following command is an example that uses devshell on a target named linux-yocto:

$ bitbake linux-yocto -c devshell

This allows us to rework the Linux kernel source code and build it in place, to avoid building it from scratch on our development machine, and change its code as needed.

Note

It is important to bear in mind that no changes made inside devshell are persistent between builds; thus, we must be careful to record any change that is important, prior to leaving it.

As we have the source at...
