Yocto project and OpenEmbedded training updated to Krogoth

yocto

Continuing our efforts to keep our training materials up-to-date we just refreshed our Yocto project and OpenEmbedded training course to the latest Yocto project release, Krogoth (2.1.1). In addition to adapting our training labs to the Krogoth release, we improved our training materials to cover more aspects and new features.

The most important changes are:

  • New chapter about devtool, the new utility from the Yocto project to improve the developers’ workflow to integrate a package into the build system or to make patches to existing packages.
  • Improve the distro layers slides to add configuration samples and give advice on how to use these layers.
  • Add a part about quilt to easily patch already supported packages.
  • Explain in depth how file inclusions are handled by BitBake.
  • Improve the description about tasks by adding slides on how to write them in Python.

The updated training materials are available on our training page: agenda (PDF), slides (PDF) and labs (PDF).

Join our Yocto specialist Alexandre Belloni for the first public session of this improved training in Lyon (France) on October 19-21, 2016. We are also available to deliver this training worldwide at your site, contact us!

Embedded Linux Projects Using Yocto Project Cookbook

Embedded Linux Projects Using Yocto Project Cookbook Cover

We were kindly provided a copy of Embedded Linux Projects Using Yocto Project Cookbook, written by Alex González. It is available at Packt Publishing, either in an electronic format (DRM free) or printed.

It is written as a cookbook so it is a set of recipes that you can refer to and solve your immediate problems instead of reading it from cover to cover. While, as indicated by the title, the main topic is embedded development using Yocto Project, the book also includes generic embedded Linux tips, like debugging the kernel with ftrace or debugging a device tree from U-Boot.

The chapters cover the following topics:

  • The Build System: an introduction to Yocto Project.
  • The BSP Layer: how to build and customize the bootloader and the Linux kernel, plenty of tips on how to debug kernel related issues.
  • The Software layer: covers adding a package and its configuration, selecting the initialization manager and making a release while complying with the various licenses.
  • Application development: using the SDK, various IDEs (Eclipse, Qt creator), build systems (make, CMake, SCons).
  • Debugging, Tracing and Profiling: great examples and tips for the usage of gdb, strace, perf, systemtap, OProfile, LTTng and blktrace.

The structure of the book makes it is easy to find the answers you are looking for and also explains the underlying concepts of the solution. It is definitively of good value once you start using Yocto Project.

Bootlin is also offering a Yocto Project and OpenEmbedded training course (detailed agenda) to help you start with your projects. If you’re interested, join one of the upcoming public training sessions, or order a session at your location!

Bootlin at FOSDEM 2015

FOSDEM BannerFor many open-source developers based in Europe, the FOSDEM is probably the most useful, interesting and exciting conference. Once again this year, several Bootlin engineers will attend the conference:

  • Maxime Ripard, mainly involved in Allwinner related kernel development, as well as more recently OpenWRT support for Marvell platforms
  • Antoine Ténart, involved in Marvell Berlin related kernel development, and one of the developers of our Yocto Project and OpenEmbedded training course
  • Alexandre Belloni, involved in Atmel processors related kernel development, and also one of our Yocto expert.
  • Thomas Petazzoni, involved in Marvell EBU processors related kernel development, and doing a lot of Buildroot contributions.

If you are attending, and want to know more about Bootlin, or discuss career or project opportunities, do not hesitate to contact us prior to the conference. Many of us will probably attend a significant number of talks from the Embedded track, so it should be easy to find us.

Last but not least, Alexandre Belloni will be giving a talk about Starting with the Yocto Project, which will take place on Sunday, at 3 PM in room Lameere.

Finally, Thomas Petazzoni has organized and will participate to the Buildroot Developers Meeting organized right after FOSDEM, and sponsored by Google and Mind.

Yocto Project and OpenEmbedded training materials published

Yocto Project and OpenEmbedded trainingAs we announced in out latest newsletter, we recently launched a new Yocto Project and OpenEmbedded development training course.

The first public session will take place in Toulouse, France on November 18-20 and we still have a few seats available. We can also deliver on-site sessions at the location of your choice, see our Training cost and registration page for more details.

However, what brings us here today is that we are happy to announce the release of all the training materials of this new course: like all Bootlin training materials, they are available under the Creative Commons Attribution Share-Alike license.

Fully committed to its knowledge sharing principles, Bootlin has chosen to publish those materials even before the first session has taken place.

The materials available are:

We of course welcome reviews, feedback and comments about these materials, in order to improve them where needed. Send us your comments!

Bootlin registered as Yocto Project Participant.

Yocto_Project_Badge_Participant_Web_RGB
Earlier this month, Bootlin applied and was elected Yocto Project Participant by the Yocto Project Advisory Board. This badge is awarded to people and companies actively participating to the Yocto Project and promoting it.

We have mainly contributed to the meta-fsl-arm and meta-fsl-arm-extra layers but we also have some contributions in OpenEmbedded Core and in the meta-ti layer.

Bootlin offers a Yocto Project and OpenEmbedded training course that we can deliver at your location, or that you can attend by joining one of our public sessions. Our engineers are also available to provide consulting and development services around the Yocto Project, to help you use this tool for your embedded Linux projects. Do not hesitate to contact us!
