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.

Fetching the source code

When we download the Poky source code, we download the metadata collection and the BitBake tool. One of the main features supported by BitBake is additional source code fetching.

The ability of fetching external source code is as modular and flexible as possible. For example, every Linux-based system includes the Linux kernel and several other utilities that form the root filesystem, such as OpenSSH or BusyBox.

The OpenSSH source code is available from its upstream website as a tar.gz file hosted on an HTTP server, while the Linux kernel release is in a Git repository. Therefore, BitBake can easily fetch those two different instances of source code.

BitBake offers support for many different fetcher modules that allow the retrieval of tarball files and several other SCM systems, such as the following:

  • Amazon AWS S3
  • Android repo
  • Azure Storage
  • Bazaar
  • ClearCase
  • CVS
  • FTP
  • Git
  • Git Annex
  • Git submodules
  • HTTP(S...
