Zephyr Project Meetup (March 18, 2026) - Jena, Germany
2026-03-18 17:30 - 21:00
Meet Zephyr – Moderne MCU-Applikationen am Beispiel des CAN Bus
Von Zephyr zu CANnectivity – eine Safari durch moderne Werkzeugketten.
Im Rahmen unseres nächsten Meetups in Jena – einem weiteren Hands-on-Workshop – nehmen wir dich mit auf eine Reise durch Beispiele, Tests und fertige Applikationen aus dem Makrokosmos rund um das „Zephyr RTOS Project“. Aus den unzähligen Zephyr Treiber APIs und Subsystemen werden wir uns an diesem Abend intensiver mit der bestehenden CAN-Bus Implementierung beschäftigen. Fokus wird dabei auf der konsequenten Nutzung der vorhandenen Hardware-gnostischen Software und deren Architektur liegen – nicht nur von Zephyr, sondern auch der noch jungen, aber durchaus schon sehr prominenten Zephyr Downstream Applikation „CANnectivity”.
Auch dieses Mal arbeiten wir nur minimal im Editor. Stattdessen analysieren wir „guten” und „schlechten” Zephyr-Applikationscode, diskutieren bewährte Architektur- und Vorgehensmodelle und grenzen diese von weniger geeigneten Ansätzen ab. Darüber hinaus zeigen wir, wie Zephyr als Technologie zur Kostenoptimierung im Entwicklungsalltag beiträgt und wie mithilfe moderner Entwicklungswerkzeuge MCU-Software vollständig ohne konkrete Zielhardware entwickelt werden kann.
Tobias Kästner von der inovex GmbH aus Karlsruhe wird uns mit seinem Impulsvortrag das Konzept von „Zephyr Downstream” vorstellen und daran reflektiert einige freie Zephyr Applikationsprojekte (Produkte) bewerten – unter anderem auch „CANnectivity”.
Stephan Linz von der Navimatix GmbH aus Jena führt euch dann durch den praktischen Workshop. Ihr integriert dabei „CANnectivity” auf ein FRDM-MCXN947 Entwicklungsboard von NXP, baut dieses mit zusätzlichen Aufsteck-Boards um weitere CAN-Schnittstellen aus und lernt die einzelnen Integrationsschritte mit den bestehenden und immer gleichen Zephyr Werkzeugen, Beispielen und Tests abzusichern.
Der Abend wird mit einer kleinen Live-Demonstration enden. Dabei wird gezeigt, wie die am Abend genutzte Applikationssoftware in geeignete Simulations- und Emulationsumgebungen integriert und, zusammen mit realer Elektronik, diese auch zu Hybridaufbauten überführt werden kann.

Testing and quality assurance in Zephyr RTOS - Meetup
2026-05-07 16:15 - 19:30
Zephyr RTOS is an open source operating system in the embedded world and is increasingly used in both industrial products and IoT devices. In this event, we will take a closer look at how to work systematically with testing and quality in Zephyr-based projects.
The lecture will, among other things, introduce Zephyr’s test frameworks, including ztest for unit tests and Twister for automated test execution.
Develco will demonstrate how to use hardware-in-the-loop testing, where Twister builds firmware, flashes it to a physical target and executes tests directly on the hardware. For this purpose, some hardware will be used, specifically for testing. Practical examples will be based on concrete Zephyr code and show how to structure test cases and automate validation of embedded functionality. Mjølner will share a real-life example of rapid product development with Zephyr, where Test-Driven Development is the driving force under unclear and constantly changing requirements.
There will be two 30-45 minute technical presentations – one hosted by Develco and one by Mjølner Informatics. There will be time for questions and networking with pizza afterwards. Henrik Brix Andersen, who sits on the Zephyr Technical Steering Committee and Architecture Working Group, will be present during the event and will be happy to take questions.
Target group
Embedded developers, firmware engineers and technically interested people who work with or want to work with Zephyr RTOS and modern testing methods in embedded systems.
Prerequisites
A certain technical level is a good prerequisite for this event, but everyone with an interest in embedded software and modern development tools is welcome. If you have specific issues or test scenarios you would like to have covered, please contact the organizer before the lecture.
Outcome
Participants will receive a practical introduction to Zephyr’s testing tools and an understanding of how to establish automated tests, both in software and directly on hardware, as a direct part of the development process.

Embedded Development With Rust on Zephyr - Rust Week 2026
2026-05-18 09:30 - 12:00
Joining RustWeek 2026? 🦀
David Brown, Senior Engineer at Linaro and Security Chair for the The Zephyr Project, will lead a workshop on Embedded Development With Rust on Zephyr.
The Zephyr RTOS is a mature operating system ecosystem, with support for over 900 boards, and numerous features. Recently, it has become possible to develop applications in Rust running on Zephyr. There are a lot of pieces involved in doing this, both in setting up a development environment for Zephyr, configuring and building Zephyr, as well as integrating this with a Rust application.
This workshop will begin with setting up a Zephyr development environment, as well as a general overview of how Zephyr works, from directory layout, configuration, building and such. The goal will be to run a basic C hello world program on Zephyr. We will then move on to running a Rust application, covering the additional configuration, along with how Zephyr’s build system and cargo interact. This will end with a similar basic Rust hello world program running on the same target.
We will then move to more advanced areas of the parts of the Zephyr API that are currently exposed to Rust. The result of this will be a small multi-threaded program with interacting threads.
As the Zephyr API surface is large, and the Rust work is still in its early stages, we will cover how to safely use parts of the C API directly from Rust. This will include some of the common gotchas of this approach. Lastly, we will cover what is needed to make Rust-friendly interfaces to new parts of the Zephyr API, with the goal of hoping to bring more contributions to the project.
There will be an overview of the various tradeoffs between different modes of developing Rust programs on embedded devices, including bare metal, a “thin” platform, such as Embassy, or RTIC, and a richer RTOS interface, such as Rust on Zephyr.
Prerequisites:

A laptop setup for Rust development. The course will focus on Mac or Linux machines. WSL2 might work, but there are challenges to accessing the hardware that will have to be done manually.
The https://docs.zephyrproject.org/latest/develop/getting_started/index.html guide should be followed to setup the laptop to build and run Zephyr projects. Although we will cover this process, and assist where there are issues, following these directions before the workshop will allow more time to be spent on the Rust on Zephyr specifics. The participant should be able to run the hello world example on the qemu_x86 target.
A Nordic ABCxyz board (provided)
An available USB port
A basic working knowledge of Rust programming in a desktop environment. You should be familiar with Cargo.toml and have written some Rust code.
Knowledge of embedded or microcontroller programming

Pouch: Portable Data for Zephyr Devices // Zephyr Tech Talk #034
2026-07-09 15:00 - 16:00
Pouch is an open source, transport-agnostic protocol that can help embedded developers move data reliably across devices, gateways, transports, and cloud services.
In this Zephyr Tech Talk, Benjamin Cabé will be joined by Daniel Mangum to discuss how this lightweight application-layer protocol fits naturally with Zephyr-based systems, especially when building connected products that involve Bluetooth devices, gateways, intermittent connectivity, or multiple network hops (i.e. virtually any connected product, right?).
We’ll look at how Pouch lets applications stay independent from the underlying transport, making it easier to reuse the same data model across BLE, HTTP, gateways, and cloud backends. We’ll also show how to try the Pouch SDK with Zephyr today on Bluetooth development boards such as the nRF52840 DK or FRDM-MCXW71.

2026-07-16 19:00 - 20:00
Zephyr is winning embedded – 1,000+ supported boards, used by kapa.ai customers like Nordic Semiconductor, Silicon Labs and Espressif Systems. But the learning curve is real: RTOS kernel, Devicetree, the build system. You end up digging through docs, GitHub issues and Discord for the one answer you need.
The instinct is to ask a generic AI tool. The problem is that generic models guess. They blend everything they’ve ever seen into a fluent, plausible answer – right or not for your SDK, board, or version.
Grounded AI solves this: an assistant trained only on real sources, citing them, and saying “I don’t know” instead of hallucinating.
Benjamin Cabé from Zephyr and Emil Sorensen from kapa.ai will show what “grounded” means in practice, run real Zephyr questions live on their Ask AI deployment, and might even open the editor to play with the hosted MCP server.
Register for this joint Zephyr Project and Kapa webinar on how grounded AI is changing the embedded developer support experience, from the docs to the IDE. Live demo included. Register for the webinar today!

Evaluating the Real-Time Behavior of Zephyr Systems / Zephyr Tech Talk #035
2026-07-22 15:00 - 16:00
How can we evaluate the real-time behavior of Zephyr systems, and build confidence that they behave predictably over long periods of time?
In this Zephyr Tech Talk, Jan Altenberg from Open Source Automation Development Lab (OSADL) eG will join Benjamin Cabé to discuss how Zephyr can be tested with zyclictest, drawing on 20 years of experience from the OSADL QA Farm and its long-running real-time testing infrastructure.
We’ll look at what it takes to collect meaningful latency data over time, what long-term testing reveals about both software and hardware behavior, and how feedback from the Zephyr community can help shape this work.

Open Source Summit: Korea 2026
2026-08-11 - 2026-08-12
Open Source Summit is the premier event for open source developers, technologists, and community leaders to collaborate, share information, solve problems, and gain knowledge, furthering open source innovation and ensuring a sustainable open source ecosystem. It is the gathering place for open-source code and community contributors.
Open Source Summit is not a single-focus, niche event—it’s the big tent that unites the full spectrum of open source technologies and communities. Whether you work in cloud infrastructure, Linux kernel development, AI/ML, embedded systems, DevOps, security, or safety-critical systems, Open Source Summit offers a shared space to exchange ideas, make connections, and learn across domains. It’s where technologists who don’t typically land in the same room get a chance to collaborate.
At the same time, Open Source Summit brings in the leaders and practitioners who support the ecosystem from non-technical angles: open source program office (OSPO) staff, legal experts, policy advocates, standards organizations, equity champions, community managers, and foundation leaders. Together, they help shape the frameworks, culture, and strategy that make open source work.
This event serves as a strategic checkpoint for the open source movement. It’s where conversations happen about not only what’s being built—but how and why. From sustainability and funding models to licensing, AI alignment, security, and governance, Open Source Summit brings clarity and direction to a fast-changing open source landscape.
Whether you’re deep in code or focused on enabling the communities and structures that support it, this is where your work gains momentum and impact.

Zephyr Track
The Zephyr track is for developers using or considering Zephyr in embedded products. Sessions will explore project advancements, security, tooling, and real-world applications across industries.
Featured session
Wednesday August 12, 2026 14:55 – 15:25 KST – Zephyr RTOS: 10 Years After Applying OSS Best Practices – Kate Stewart, The Linux Foundation
Zephyr initially set out to solve a problem that many embedded teams quietly struggled with: how to build dependable real-time systems without being locked into a single vendor, toolchain, or proprietary stack. The project introduced a new model built around portability, adoption of open source and security best practices, modern tooling, and a shared ecosystem of drivers and middleware.
From the start, there was the commitment from the start apply known best practices to its development. While Zephyr is a different code base, a lot of the lessons learned from developing the Linux Kernel were applied. The project has also focused on incorporating security best practices from the start which now enables it to make compliance easier for manufacturers looking to conform to the emerging Cybersecurity Resilence Act (CRA).
Best practices have also enabled the project to work towards achieving formal safety certification for 61508 and 26262. The project has achieved 61508 concept approval at this point, as is working towards formal certification, using a combination of traditional V-Model analysis, and innovative techniques to keep up with the speed of open source development.
