Covid-19: Bootlin proposes online sessions for all its courses

Tux working on embedded Linux on a couchLike most of us, due to the Covid-19 epidemic, you may be forced to work from home. To take advantage from this time confined at home, we are now proposing all our training courses as online seminars. You can then benefit from the contents and quality of Bootlin training sessions, without leaving the comfort and safety of your home. During our online seminars, our instructors will alternate between presentations and practical demonstrations, executing the instructions of our practical labs.

At any time, participants will be able to ask questions.

We can propose such remote training both through public online sessions, open to individual registration, as well as dedicated online sessions, for participants from the same company.

Public online sessions

We’re trying to propose time slots that should be manageable from Europe, Middle East, Africa and at least for the East Coast of North America. All such sessions will be taught in English. As usual with all our sessions, all our training materials (lectures and lab instructions) are freely available from the pages describing our courses.

Our Embedded Linux and Linux kernel courses are delivered over 7 half days of 4 hours each, while our Yocto Project, Buildroot and Linux Graphics courses are delivered over 4 half days. For our embedded Linux and Yocto Project courses, we propose an additional date in case some extra time is needed to complete the agenda.

Here are all the available sessions. If the situation lasts longer, we will create new sessions as needed:

Type Dates Time Duration Expected trainer Cost and registration
Linux Graphics (agenda) Sep. 22, 23, 24 and 25, 2020 14:00 – 18:00 (Paris time) 16 h Paul Kocialkowski 519 EUR + VAT* (register)
Yocto Project (agenda) Sep. 28, 29, 30, Oct. 1, 2, 2020 14:00 – 18:00 (Paris time) 16 h Maxime Chevallier 519 EUR + VAT* (register)
Embedded Linux (agenda) Sep. 28, 29, 30, Oct. 1, 2, 5, 6 2020. 17:00 – 21:00 (Paris), 8:00 – 12:00 (San Francisco) 28 h Michael Opdenacker 829 EUR + VAT* (register)
Buildroot (agenda) Oct. 1, 2, 5, 6, and 8, 2020 14:00 – 18:00 (Paris time) 16 h Thomas Petazzoni 519 EUR + VAT* (register)
Embedded Linux (agenda) Nov. 2, 3, 4, 5, 6, 9, 10, 12, 2020. 14:00 – 18:00 (Paris), 8:00 – 12:00 (New York) 28 h Michael Opdenacker 829 EUR + VAT* (register)
Linux kernel (agenda) Nov. 16, 17, 18, 19, 23, 24, 25, 26 14:00 – 18:00 (Paris time) 28 h Alexandre Belloni 829 EUR + VAT* (register)

* VAT: applies to businesses in France and to individuals from all countries. Businesses in the European Union won’t be charged VAT only if they provide valid company information and VAT number to Evenbrite at registration time. For businesses in other countries, we should be able to grant them a VAT refund, provided they send us a proof of company incorporation before the end of the session.

Each public session will be confirmed once there are at least 6 participants. If the minimum number of participants is not reached, Bootlin will propose new dates or a full refund (including Eventbrite fees) if no new date works for the participant.

We guarantee that the maximum number of participants will be 12.

Dedicated online sessions

If you have enough people to train, such dedicated sessions can be a worthy alternative to public ones:

  • Flexible dates and daily durations, corresponding to the availability of your teams.
  • Confidentiality: freedom to ask questions that are related to your company’s projects and plans.
  • If time left, possibility to have knowledge sharing time with the instructor, that could go beyond the scope of the training course.
  • Language: possibility to have a session in French instead of in English.

Online seminar details

Each session will be given through Jitsi Meet, a Free Software solution that we are trying to promote. As a backup solution, we will also be able to Google Hangouts Meet. Each participant should have her or his own connection and computer (with webcam and microphone) and if possible headsets, to avoid echo issues between audio input and output. This is probably the best solution to allow each participant to ask questions and write comments in the chat window. We also support people connecting from the same conference room with suitable equipment.

Each participant is asked to connect 15 minutes before the session starts, to make sure her or his setup works (instructions will be sent before the event).

How to register

For online public sessions, use the EventBrite links in the above list of sessions to register one or several individuals.

To register an entire group (for dedicated sessions), please contact training@bootlin.com and tell us the type of session you are interested in. We will then send you a registration form to collect all the details we need to send you a quote.

You can also ask all your questions by calling +33 484 258 097.

Questions and answers

Q : Should I order hardware in advance, our hardware included in the training cost?
R : No, practical labs are replaced by technical demonstrations, so you will be able to follow the course without any hardware. However, you can still order the hardware by checking the “Shopping list” pages of presentation materials for each session. This way, between each session, you will be able to replay by yourself the labs demonstrated by your trainer, ask all your questions, and get help between sessions through our dedicated Matrix channel to reach your goals.

Q: Why just demos instead of practicing with real hardware?
A: We are not ready to support a sufficient number of participants doing practical labs remotely with real hardware. This is more complicated and time consuming than in real life. Hence, what we we’re proposing is to replace practical labs with practical demonstrations shown by the instructor. The instructor will go through the normal practical labs with the standard hardware that we’re using.

Q: Would it be possible to run practical labs on the QEMU emulator?
R: Yes, it’s coming. In the embedded Linux course, we are already offering instructions to run most practical labs on QEMU between the sessions, before the practical demos performed by the trainer. We should also be able to propose such instructions for our Yocto Project and Buildroot training courses in the next months. Such work is likely to take more time for our Linux kernel course, practical labs being closer to the hardware that we use.

Q: Why proposing half days instead of full days?
A: From our experience, it’s very difficult to stay focused on a new technical topic for an entire day without having periodic moments when you are active (which happens in our public and on-site sessions, in which we interleave lectures and practical labs). Hence, we believe that daily slots of 4 hours (with a small break in the middle) is a good solution, also leaving extra time for following up your normal work.

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. 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.
