Embedded Recipes 2026: Chef sponsor, 19 engineers from Bootlin, registration open

Embedded Recipes 2026The Embedded Recipes conference is coming back to Nice for the second year, and it will take place on May 27 and 28!

This community-driven event, with a unique format of a single track conference, really stands out compared to other events. To support this great initiative and for the second year in a row, Bootlin has decided to be first Chef Sponsor of the event.

A significant part of the Bootlin team will make the trip to Nice for this conference, as 19 engineers from our team will be attending. The registration is now open, and we recommend that you book your ticket early, as the number of seats is limited.

Even though the schedule for the conference has not been published yet, Bootlin CEO Thomas Petazzoni is part of the program committee for the event, and considering the high-quality submissions that were made through the Call For Papers, there is absolutely no doubt that the line-up of talks will be excellent.

In addition to the Embedded Recipes conference itself, a large number of co-located events are organized around this main event, forming the so-called Embedded Week. Already announced as co-located events:

Essentially, if you’re an embedded Linux person, and you’re not in Nice on the week of May 26-31, you’re missing out on very good content, discussions and meetings! Book your seat and trip now, and join us at Embedded Recipes!

sbom-cve-check updates: new release, meta-sbom-cve-check, possible Yocto integration, FOSDEM talk

sbom-cve-checkBack in December 2025, we announced the release of sbom-cve-check, a lightweight CVE analysis tool for your Software Bill of Materials (SBOM).

Since the release announcement, the project has continued its development, and in this blog post, we wanted to share a number of updates about this project: a new 1.1.0 release, a new meta-sbom-cve-check layer, possible integration into the Yocto Project, and a talk at FOSDEM.

Linux 6.19 released, Bootlin contributions inside

Penguin coding, AI generatedLinux 6.19 was just released yesterday, and as usual we recommend reading LWN.net articles to have a nice high-level overview of the new features brought by this release: part 1, part 2. Kernelnewbies also has a nice article.

On our side, with 160 commits it is a very strong release for our team. According to statistics, this puts Bootlin as the top 15 contributing company for this release. In addition to the patch we authored, several Bootlin engineers reviewed/merged patches from other contributors: most notably, Alexandre Belloni merged/reviewed 52 patches for the RTC and I3C subsystems, Luca Ceresoli reviewed 18 patches, Miquèl Raynal merged/reviewed 34 patches for the MTD subsystem.

Upstreaming of the AAEON UP board IO expansion Linux kernel driver

AAEON UP board familyThe UP Board family of platforms, developed by AAEON, is a series of compact, high-performance single-board computers (SBCs) widely used in the industry and embedded applications. They combine high-performance Intel processors with versatile I/O through a 40-pin Raspberry Pi-like header. At its core, an FPGA manages pin functionality, routing, and direction, enabling flexible use as I2C, UART, or GPIO. Supporting this setup in Linux is uniquely challenging and fascinating, and we were recently involved in bringing support for these I/Os upstream, successfully closing a story that had been open for seven years!

Announcing sbom-cve-check, a lightweight CVE analysis tool for your SBOM

sbom-cve-checkToday, we are happy to announce the first release of a brand new open-source project: sbom-cve-check, a lightweight CVE analysis tool for your Software Bill of Materials (SBOM). Written in Python, with minimal dependencies, and a very simple workflow in mind, sbom-cve-check will parse your SBOM (SPDX v2.2 or SPDX v3.0 currently supported), and using publicly available databases of security vulnerabilities, will generate a report of known security vulnerabilities affecting the software components listed in your SBOM.

This tool will be presented tomorrow, on December 2 at 3:40 PM during the Yocto Project Virtual Summit 2025.12 during a talk titled sbom-cve-check: Lightweight Python tooling for out-of-build CVE analysis of SPDX3 SBOMs, presented by Bootlin engineers Benjamin Robin and Olivier Benjamin.

Linux 6.18 released, Bootlin contributions inside

Penguin coding, AI generatedThe 6.18 version of the Linux kernel has just been released, and as usual we recommend our readers to look at the 6.18 merge window coverage by LWN.net (part 1, part 2) to get the best overview of the major changes in this release.

On our side, we contributed a total of 77 patches to this kernel release, and our engineers who work as maintainers review/merged 111 patches from other contributors.

Bootlin at Capitole du Libre 2025

The 2025 edition of Capitole du Libre took Capitole du Libreplace in Toulouse, France on November, 15th and 16th this year, and as in previous years, Bootlin was actively involved through a variety of contributions.

The Capitole du Libre is a major conference about Free Software in the south of France, even attracting people from other countries. This is an important opportunity for local actors to meet and share their interests and contributions to Open Source Software.

Bootlin engineer Luca Ceresoli speaks at Linux Day 2025 in Bergamo, Italy

Linux DayBootlin is happy to share that our engineer Luca Ceresoli will be speaking at Linux Day 2025 in Bergamo, Italy, on Saturday, October 25, 2025.

Luca’s talk, titled “Software updates on embedded Linux devices” (“Aggiornamenti software su dispositivi embedded Linux”), will take place from 14:00 to 15:00.

About the talk

Many of the electronic products we use every day are powered by Linux, even when we don’t see it. Like PCs, these embedded devices also need software updates to fix bugs and improve functionality. However, unlike PCs, they must perform these updates automatically and reliably, without any user intervention.

In his presentation, Luca will explain one of the most widely used techniques for achieving this: A/B updates. He will describe what they are, how they work, and the most common tools used to implement them in embedded Linux systems.

This talk is a great opportunity for developers and engineers interested in the practical challenges of maintaining and updating Linux-based devices in the field.

About Linux Day

Linux Day is an annual, nationwide event organized across Italy to promote the use and understanding of free and open-source software. Many cities host talks, workshops, and meetups aimed at both newcomers and experienced developers. The Bergamo edition continues this tradition with a full day of technical sessions, community engagement and an install party.

Meet Luca and Bootlin

If you’re attending Linux Day Bergamo 2025, don’t miss Luca’s session! Don’t hesitate to meet Luca to talk about what we do at Bootlin and open job positions!
