Overview of this book

The Yocto Project is the industry standard for developing dependable embedded Linux projects. It stands out from other frameworks by offering time-efficient development with enhanced reliability and robustness. With Embedded Linux Development Using Yocto Project, you’ll acquire an understanding of Yocto Project tools, helping you perform different Linux-based tasks. You’ll gain a deep understanding of Poky and BitBake, explore practical use cases for building a Linux subsystem project, employ Yocto Project tools available for embedded Linux, and uncover the secrets of SDK, recipe tool, and others. This new edition is aligned with the latest long-term support release of the aforementioned technologies and introduces two new chapters, covering optimal emulation in QEMU for faster product development and best practices. By the end of this book, you’ll be well-equipped to generate and run an image for real hardware boards. You’ll gain hands-on experience in building efficient Linux systems using the Yocto Project.

Using the GNU Debugger for debugging

While developing any project, from time to time, we end up struggling to understand subtle bugs. The GDB is available as a package in Poky. It is installed in SDK images by default, as was detailed in Chapter 9, Developing with the Yocto Project.

Note

To install debugging packages containing the debug symbols and tools in an image, add IMAGE_FEATURES += "dbg-pkgs tools-debug" in build/conf/local.conf.

Using the SDK or an image with the debugging packages and tools installed allows us to debug applications directly in the target, replicating the same development workflow we usually do on our machine.

The GDB may not be usable on some targets because of memory or disk space constraints. The main reason for this limitation is that the GDB needs to load the debugging information and the binaries of the debugging process before starting the debugging process.

To overcome these constraints, we can use gdbserver, included by default...
