Embedded Linux and Yocto training courses now available in Italian

Flag of ItalyBuongiorno!

For many years, we have been offering our training courses in both English and French. We are happy to announce that we are now expanding our offering towards our Italian customers: we are now able to deliver our very popular Embedded Linux system development and Yocto Project and OpenEmbedded development training courses in Italian. Those courses are delivered by a native Italian speaker, Bootlin engineer Luca Ceresoli. Luca has 20 years of experience working with embedded systems, including 15 years on embedded Linux.

Thanks to this offering, our Italian customers can enjoy a training course delivered in their native language, which obviously facilitates communication, understanding and interaction. We can offer our Embedded Linux course and Yocto course in Italian through either private on-site sessions or private on-line sessions. Contact us at training@bootlin.com for details and pricing!

New training course: Linux debugging, profiling, tracing and performance analysis

Since its inception, Bootlin has offered training courses on technical topics related to the use of Linux in embedded systems, with freely accessible training materials, and trainers with in-depth and real-life experience in their field. Based on these ideas, we have progressively extended our training portfolio over the years.

Today, we are extremely happy to announce a brand new course: Linux debugging, profiling, tracing and performance analysis. Many of our customers working on embedded Linux systems have expressed interest in diving into these complex topics, so we’ve created this course to:

  1. Give enough background information about how Linux works to be able to have a solid reasoning when investigating performance issues or simply bugs. Our course therefore details how user-space vs. kernel-space works, scheduling, and memory management, as a prerequisite to understanding better how Linux works.
  2. Give a strong introduction to the most important debugging, profiling and tracing tools in Linux, which are often not easy to get started with. We cover a very large spectrum of tools: strace, gdb, perf, ftrace, LTTng, kgdb, kmemleak, and many more. All these tools are illustrated through practical examples.

See the complete agenda for this course: debugging-online-agenda.pdf. The complete training materials will be freely available after the first session has been delivered, end of November 2022.

This course is currently being prepared by Bootlin engineer Clément Léger, who will also be teaching this course. Clément has a deep knowledge of how CPUs work and how Linux runs on a given CPU architecture, by having ported the Linux kernel to a brand new CPU architecture.

While the first session of this course will be delivered to a private customer, we have already scheduled a first public session which will take place on January 30, 31, Feb 1, 2, 2023, plus an extra session on Feb 3, 2023 if needed to cover all topics/questions. This session will take place each day from 14:00 to 18:00 UTC+1 (Paris time). Registration takes place directly online: the pricing is 569 EUR per seat at the discounted rate, or at 669 EUR per seat at the normal rate.

We can also organize a private session of this course for your team/company, either on-line or on-site: contact us to request a quote if you’re interested.

Embedded Linux Boot time optimization: training and webinar

Bootlin has been helping its customers optimize the boot time of embedded Linux systems for many years, ensuring that these systems meet their startup time requirements. Thanks to this, Bootlin has accumulated a significant experience in this field.

Next week, Bootlin is organizing or participating to two events related to Embedded Linux boot time optimization:

In addition, if you need help and support to optimize the boot time of your Embedded Linux systems, do not hesitate to as we offer engineering services, thanks to which we can take your existing Embedded Linux system, and significantly reduce its startup time to meet your requirements.

Bootlin “Buildroot system development” course updated to Buildroot 2021.02

Bootlin has been offering for several years a Buildroot system development course, which allows engineers interested in learning and understanding the Buildroot embedded Linux build system to get up to speed very quickly.

In preparation for our public Buildroot system development course next week, we updated our training materials, both slides and labs to Buildroot 2021.02, which is the latest stable Buildroot release as of today, and is also a Long Term Support release.

Buildroot slide

In addition to updating to a newer Buildroot version, we also use newer U-Boot and Linux versions for the practical labs on BeagleBone Black Wireless. The slides were also updated to document some new features that appeared between 2020.02 and 2021.02. If you’re interested, check out the materials on the training page.

We have one seat left for this training course next week, which will be taught by long-time Buildroot contributor and developer Thomas Petazzoni. Register now and take the last seat!

New training course: embedded Linux boot time optimization

For many embedded products, the issue of how much time it takes from power-on to the application being fully usable by the end-user is an important challenge. Bootlin has been providing its expertise and experience in this area to its customers for many years through numerous boot time optimization projects, and we have shared this knowledge through a number of talks at several conferences over the past years.

We are now happy to announce that we have a new training course Embedded Linux boot time optimization, open for public registration. This training course was already given to selected Bootlin customers and is now available for everyone.

Embedded Linux boot time optimization

The training course will be lead by Michael Opdenacker, Bootlin’s founder, and author of several publications on the topic of boot time optimization. The course is organized over 4 sessions of 4 hours, with a significant fraction of time spent on practical demonstrations showing on a real-life example the techniques to measure and reduce the boot time of an embedded Linux system.

As usual with Bootlin, the training materials are fully available: Agenda, Slides and Practical lab instructions.

Boot time optimization slide

Our first course open for public registration will take place from April 6th to April 9th, 2021, from 14:00 to 18:00 UTC+2 (Paris time) on each day. The session cost is 519 EUR if you take advantage of the early bird price available until March 9th. Otherwise, the regular rate is 619 EUR. You can register now for this course on Eventbrite.

Also, if you’re interested in organizing a dedicated session for your company, do not hesitate to contact us.

Bootlin training courses for beginning of 2021

It’s the beginning of 2021, and Bootlin’s offering of online training courses continues. We have dates available for our 5 training courses, at an affordable cost, and with the same quality characteristics of all Bootlin courses: trainers with proven in-field experience, fully open-source training materials and worldwide recognized training contents.

Here are the dates of our upcoming sessions:

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:

* 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.

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 training course available on STM32MP1 platform

Back in May 2019, we announced the availability of our Embedded Linux system development course on the STMicroelectronics STM32MP1 platform, in addition to the already supported Microchip SAMA5D3 Xplained board.

In the context of our partnership with STMicroelectronics, we are now happy to announce the availability of our Yocto Project and OpenEmbedded development training also on the STM32MP1 platform for the practical labs. We now support either the BeagleBoneBlack Wireless or the STMicroelectronics STM32MP1 platforms for this training course.

The complete training materials are available: detailed agenda, slides and practical labs. The complete source code of the training materials is also available in our Github repository.

Publication of Linux graphics training materials

Back in June 2019, we announced the availability of a new training course, Displaying and rendering graphics with Linux. At the time of this announcement, the training materials were not available though.

Since then, Bootlin engineer Paul Kocialkowski has been very busy preparing those training materials, and has successfully delivered the first edition of this course to one of our customers in Spain early September. After taking the time to polish those training materials following this first course, we are now very happy to publish and share this 200+ slides deck, covering a wide range of graphics related topics:

  • Image and color representation
  • Basic drawing
  • Basic and advanced operations
  • Hardware aspects overview
  • Hardware for display
  • Hardware for rendering
  • Memory aspects
  • Performance aspects
  • Software aspects overview
  • Kernel components in Linux
  • Userspace components with Linux

See also the detailed agenda of this training course. The LaTeX source code for all our training materials, including this graphics training, is available in a Git repository. It is worth mentioning that this training only consists of slides and demos, and does not include practical labs done by the participants, in order to keep the training logistics manageable and the duration reasonably short (2 days).

Here are a few slides showing various aspects of this training course:

By publishing this training materials right after our first course, and under the Creative Commons CC-BY-SA license, Bootlin sticks to its commitment of publishing all its training materials under a free documentation license, to better spread the knowledge in the entire embedded Linux community.

We are available to deliver this Displaying and rendering graphics with Linux course anywhere in the world, at your location. Contact us for more details.

Free seats in embedded Linux and kernel training sessions (Mar 2019)

Student penguinsAt Bootlin, we owe a lot to the Free Software community, and we’re doing our best to give back as much as we can.

One way of doing that is welcoming community contributors in our public training sessions organized in France. We’ve done that multiple times several years back, and this allowed us to meet very interesting people (who even had very valuable experience and points of view to share with the other course participants), while of course giving them extra knowledge that they can use for further contributions.

Here are the next sessions in which we can offer a free seat:

See our Free training seats page for practical details about how to apply.

Don’t hesitate to apply to this free seat. In past editions, we didn’t have so many people applying, and therefore you have a real chance to get selected!
