I'm happy to have a talk proposal accepted at the Embedded Linux Conference Europe in Prague, between Oct. 7 and 9.
Both secure boot and A/B updates techniques are well documented, but most often without considering their mutual requirements. In this presentation, I will share solutions I found and used in a recent project. I will also share implementation details with U-Boot and @yoctoproject@fosstodon.org .
The schedule of the Embedded Linux Conference Europe and Open Source Summit Europe in early October in Prague has just been published:
https://events.linuxfoundation.org/embedded-linux-conference-europe/program/schedule/
I hope this can convince you (and your management if needed) to join us in Prague (week of Oct. 5-9... there's also a Yocto Developer Day on Oct. 6!) for several days of intense knowledge sharing and networking. All this will make your daily work easier and smarter on the following weeks and months.
The Call for Papers has opened for Yocto Project Workshop on Oct. 6 in Prague, on the day before the Embedded Linux Conference Europe, and sadly during Linux Plumbers 🫢
This is a great opportunity to share your experience with your favorite build system as well as your contributions and ideas. So, don't hesitate to submit a topic at https://pretalx.com/ypdd-2026/cfp, especially if you have never done it before, as we are always keen to welcoming new speakers.
I hope to see you there!

Just found this on The Linux Foundation events page. Open Source Summit Europe should be in Glasgow, Scotland in September 2027. After Prague in 2026, it's also likely to be the next location of the Embedded Linux Conference Europe!
https://events.linuxfoundation.org/
As far as I recall, it's the first time we have the next location before event is over.
Just found that the 2026 edition of the Linux Plumbers Conference will be in Prague 🇨🇿 , Oct. 5-7, on the same week as Open Source Summit Europe and Embedded Linux Conference Europe.
Save the dates and see you there! That's too early to book my train tickets though 🤔
It's been 2 years since I announced my new journey as an independent embedded Linux engineer and trainer.
I launched Root Commit, contributed to Yocto/Linux kernel, shared my learning through 18 talks (I was surprised when counting!), created hands-on training, published 6 YouTube videos, and became a Yocto Ambassador. I traveled sustainably (1 flight in 2 years), reconnected with old friends and made new ones. I'm grateful for everyone’s support! ❤️

Perfect day starting with a cup on Indian tea with milk, before working on embedded Linux with @yoctoproject@fosstodon.org .
Thanks to my friend Beleswar Prasad Padhi for bringing this incredibly tasty tea from India and to the @embeddedrecipes@fosstodon.org conference for allowing us to meet again.
First thing I did in 2026? Replace Ubuntu by Debian 13.
Here are my reasons:
- Have a distribution really backed by a community.
- Enjoy access to all updates, instead of being told to subscribe to a service.
- Get rid of snaps, opaque and disk space hungry containers storing your data in obscure locations.
- Gaining productivity by switching to a pure GNOME desktop,
- Stop supporting an organization that denigrates other open source projects, such as Yocto.
Are you interested in learning the internals of your Linux OS? A great way to start is with Embedded Linux and with the RISC-V architecture which is less complicated than recent ARM systems.
Check-out the latest version of my "Embedded Linux From Scratch in 50 minutes (on RISC-V)" tutorial, given last Sunday at the JDLL conference in Lyon, France: https://rootcommit.com/pub/conferences/2026/jdll/embedded-linux-from-scratch/embedded-linux-from-scratch-riscv.pdf
Build and understand your own Embedded Linux system on a virtual RISC-V platform, using these step by step instructions.
The slides of my presentation about the meta-riscv Yocto layer are available at
You'll see what our small contributor community has achieved so far and what it could achieve if you get involved too.
For me, the events in Nice were also the opportunity to meet for the first time Yixun Lan, the SpacemiT SoC kernel maintainer, and meet Drew Fustini again, the T-Head and Tenstorrent SoC maintainer. I also had Khem Raj in the room, our layer maintainer.
It's official, there will be a @yoctoproject@fosstodon.org workshop at @embeddedrecipes@fosstodon.org 2026 too. Looking back at the fond memories from the 2025 edition, I'm excited to get back to Nice, hoping to meet you there!

- To give visibility to your work and attract contributors
- To show what's possible with our favorite build system
- To pinpoint issues you faced and propose improvements
- To get your employer to fund your trip to Nice and Embedded Recipes!
Just realized that Coverity Scan has stopped scanning the Linux kernel sources for vulnerabilities. The last analysis was on Dec. 1, 2025.
https://scan.coverity.com/projects/linux
Does anyone have details to share about what happened? No need to remind me this shouldn't be a surprise with proprietary software...
Here are the events I'm planning to attend in the next months: (2/2)

You may wonder about the yellowish background color of the presentation screen. I realized, but too late, that my desktop's "Night Light" mode was on. This wasn't obvious in the room, but video recording amplified it. You can see I'm caring for your eyesight too 😅
The 5.3 version of @yoctoproject@fosstodon.org has been released today.
It comes a bit later than expected because of the introduction of the "bitbake-setup" tool and the termination of the "poky" repository as a combo layer.
I like Yocto's ability to introduce disruptive changes in newer versions. This is a good sign that the project is well alive and can still improve its core.
See the official manual for the full release and migration notes: https://docs.yoctoproject.org/dev/migration-guides/release-5.3.html
Greg KH: "Debian, Yocto, they run the world"
Greg Kroah-Hartman shares with Shuah Khan many aspects of his experience as a Linux Kernel developer and maintainer. You'll learn interesting details about kernel development, managing changes and finding bugs. Greg also shares insightful tips about managing your time to serve multiple important roles in the same week.
Last but not least, Greg shares his views about the most successful Linux based projects 😉
Linux 6.18 was released last night, and it's already running on my tiny PocketBeagle2 board.
See all the details about this new release on the "Linux Changes" wiki page: https://kernelnewbies.org/LinuxChanges
Check out my "Testing mainline Linux kernel and bootloader" presentation at the "OpenEmbedded Workshop" in Brussels last February: https://rootcommit.com/pub/conferences/2025/oe-workshop/yocto-mainline-linux-uboot/yocto-mainline-linux-uboot.pdf for details about how to do this by yourself with the help of @yoctoproject@fosstodon.org .
You can also attend my next Yocto course: https://rootcommit.com/training/yocto/ 😁
Happy to announce that we secured a BoF slot for @openembedded@fosstodon.org / @yoctoproject@fosstodon.org at the @fosdem@fosstodon.org conference in Brussels on Saturday, January 31 (11:00 am).
Quick announcements may be made and you will be able to ask questions, share experience, and learn from others. That will also be an opportunity to connect with other contributors and users, and have a fun time together. Beware, some edible items may fly over our heads 😇
I hope to meet you there!
Happy to share that I will speak at the OpenEmbedded Workshop on Feb. 2 in Brussels. I will share my experience adding support for new boards.
Of course, this should help you build your own BSP layers, but the main goal is to incite people to contribute more MACHINEs to community BSP layers, which are where collaboration really happens.

First time I find this Wikipedia page about Linux kernel history:
https://en.wikipedia.org/wiki/Linux_kernel_version_history
For each kernel release, it's great:
- To know when it was first released
- To know when it will reach its End Of Life (EOL)
- To know the main changes it brings
I will mention it in Root Commit's Linux kernel course:
https://rootcommit.com/training/linux-kernel/
RE: @yoctoproject@fosstodon.org
Registration for the Yocto Project Workshop on May 29 in Nice, France, is now open.
I'm also honored to be part of the schedule (just released too), presenting the meta-riscv BSP layer, its achievements, and all the opportunities it offers to people interested in contributing to RISC-V and to the Yocto ecosystem: https://pretalx.com/yocto-embedded-recipes-2026/talk/FABH7C/
Loving electronics, embedded software and also books? If you're going to Embedded World next week, come to The Yocto Project booth (Hall 4-648), share some coffee, experience, good company and take a Yocto bookmark home!
In addition to the "favorite commands" one, I'm happy to release a new "most useful global variables" one.
I'm printing a bunch today for visitors to our booth, but here's also a PDF version you can use to print your own:
Pour toutes celles et ceux qui habitent en France, j'ai reçu une notification du service Bloctel, qui permettait de s'opposer au démarchage téléphonique :
