meta-kiss: updates to our simple Yocto layer

Yocto is often seen as fairly complex, and at Bootlin we believe one reason for this perception is the unnecessary complexity of the BSP layers provided by silicon or board vendors, each of which often includes highly custom logic that isn’t needed. That’s why, back in 2023, we released meta-kiss, an example layer demonstrating how simple it can be to support various hardware platforms with Yocto, without relying on any vendor-provided BSP layer.

Since then, we’ve kept this layer up-to-date and added several new features. In this blog post, we’d like to highlight recent significant updates: an upgrade to Yocto Scarthgap, support for the i.MX93 FRDM platform, and the ability to build OP-TEE for the previously supported STM32MP1 platform.

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

Today, 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.

Support for Yocto buildtools added to upstream Kas

Yocto Buildtools in Kas Bootlin has recently contributed to the Kas project by adding support for Yocto Project’s Buildtools. In this blog post, we will give an overview of what Kas is, what Buildtools are, why an integration of Buildtools was deemed useful and relevant, and how to use it.

Bootlin talk at Embedded Recipes: “Yocto Project and OpenEmbedded: Recent Changes and Future Directions”

As we previously announced, Bootlin is proud to be a Chef Sponsor of Embedded Recipes 2025. A large part of our team will be attending the event, which takes place on May 14–15 in Nice, France.

We’re also excited to share that Bootlin engineer Antonin Godard will be giving a talk titled Yocto Project and OpenEmbedded: Recent Changes and Future Directions. As the official maintainer of the Yocto Project documentation, Antonin brings a unique perspective on the latest developments and upcoming changes in Yocto/OpenEmbedded. Here is the full abstract of his talk:

The Yocto Project and OpenEmbedded form the foundation of many embedded Linux systems, providing a powerful and flexible build system for custom distributions. In this talk, Antonin Godard, embedded Linux engineer at Bootlin and Yocto Project documentation maintainer, will explore recent developments in the project, including key changes in the latest releases, improvements in tooling. Attendees will gain insights into the future roadmap of Yocto/OpenEmbedded and how these changes impact developers and system integrators. Whether you’re a long-time Yocto user or just getting started, this session will help you stay up to date with the latest advancements in the ecosystem.

There’s still time to secure your seat at Embedded Recipes—don’t miss this unique single-track conference that fosters deep technical exchange and networking. And of course, take advantage of the beautiful spring weather in Nice while you’re there!

Linux kernel driver and Yocto training courses now on BeaglePlay

Last summer, we announced the availability of our Embedded Linux course on the BeaglePlay platform.

Today, we are happy to announce the publication of our Linux kernel driver development and Yocto Project/OpenEmbedded system development courses also ported on the BeaglePlay platform.

Yocto 5.0 Scarthgap released, Bootlin contributions inside

Yocto Project Summit The latest release of the Yocto Project, version 5.0, code named Scarthgap has been published a few days ago. The release notes provide the best summary of what’s new in this release. Being a Long Term Support (LTS) release, it will be maintained during 4 years with bug fixes and security updates, which makes this release particularly important for a large number of embedded Linux projects and products.

At Bootlin, we are using Yocto for a large fraction of the Linux Board Support Packages that we develop, maintain and upgrade for our customers. But we’re not only users of Yocto: we’re also contributors and maintainers. In this blog post, we’ll highlight our contributions to this release, which take various forms.

Keep your Yocto layer simple! Introducing meta-kiss, a working reference Yocto/OE setup

At Bootlin we help many of our customers using Yocto/OpenEmbedded to build the Linux software stack running on their end products. While doing that we have seen all sorts of problems caused by all sorts of complicated code in their build system setup. So we wondered what we could do to improve the overall situation.

Yocto Project Summit 2023.11: 2 Bootlin talks

The Yocto Project regularly organizes an-online conference called the Yocto Project Summit. The next edition, Yocto Project Summit 2023.11 will take place on November 28-30, from 12:00 to 18:00 UTC, and at just $40, attending is really affordable.

Yocto Project Summit

Bootlin is not only a big user of the Yocto Project, but also a significant contributor to the project, so we’re happy to announce that our two talk proposals for the Yocto Project Summit 2023.11 have been accepted. Bootlin engineers will therefore deliver the following talks:

Keep your layer simple — and here’s how, by Luca Ceresoli, on November 29, at 14:20 UTC.
How to Contribute to OpenEmbedded, Yocto, and Many Other Open Source Projects, by Michael Opdenacker, on November 30 at 12:45 UTC.

If you are a user of the Yocto Project, or intend to become one, we can only recommend you to attend this event. And of course, if you need training on Yocto Project, or engineering/support services, do not hesitate to contact us!

Yocto Project 4.2 released – Bootlin contributions inside
