Sun, 20 Jul 2025 00:00:00 +0000

A variant of this article also exists as a conference presentation.

Do you already have a job in embedded Linux but wish to be given more challenging goals? Or are you in IT, already using Linux on your own laptop, and dreaming about landing an embedded Linux job, possibly starting as your own boss? Follow my advice in a patient and consistent way, and you will achieve your goals in less than 12 months.

Introducing Yocto Project Overview Seminars

Thu, 27 Feb 2025 00:00:00 +0000

Following discussions with a customer, and as a teaser for our Yocto Project and OpenEmbedded course, we are now offering a 1-day overview seminar on this topic.

The main goal is to give you a clear view of the Yocto Project and the value it can bring to your embedded Linux device projects. You will have a guided view of its main features and quick demos, all done in an engaging and interactive way.

Booting the Raspberry Pi 5 with the Mainline Linux Kernel

Wed, 19 Feb 2025 00:00:00 +0000

If you have other boards, read on, these instructions support multiple other Raspberry Pi boards.

Hardware

In this tutorial, we assume you have the Raspberry Pi Debug Probe to access the board’s serial port. You could use the GPIO UARTs too, but they are neither enabled by default at the bootloader level nor as a kernel console. Enabling them for serial console access would slightly complicate these instructions.

Video replay: Yocto Project devtool hands-on

Wed, 15 Jan 2025 00:00:00 +0000

I’ve just produced a 4K video replay of my Devtool Hands-on Class at Yocto Project Summit 2024.12.

Here are the main reasons for shooting such a video:

Compared to the official recording, this video is shorter without the pauses waiting for participants to complete their instructions.
The video can be recorded at a better quality, both in terms of video and audio.
The issues found during the presentation have been corrected.
It’s possible to show presentation slides and command line terminals on the same screen.

Make it Stick book review

Sat, 05 Oct 2024 00:00:00 +0000

I’ve finished reading a very insightful book about learning and teaching: Make It Stick by Peter C. Brown, Henry L. Roediger III and Marc A. McDaniel at Harvard University Press.

I am very grateful to Michael Estner for recommending this book to me. I feel it is now my turn to promote it.

Writing a new story

Mon, 27 May 2024 00:00:00 +0000

LinkedIn posts quickly fade out from view and may not last forever. Here is a copy of my most successful post in 2024.

Last Friday was my last day at Bootlin, the company which I created 20 years ago.

Bootlin is in good hands now, and has become a great contributor to many Open Source projects. I stayed there for three more years after selling it in 2021 to two of its engineers, Thomas Petazzoni and Alexandre Belloni. This was a very good experience to get back to engineering, especially contributing to the Yocto Project, teaching training sessions and sharing experience through speaking at international conferences. Bootlin has also managed to hire incredibly talented engineers over the years. However, working as an employee didn’t leave enough time to explore as many new techniques and resources as I was interested in.
