When the Zephyr project launched in 2016, the lack of standardized security best practices in the IoT market segment was a known problem. It was one of the goals the project wanted to address, and started working on from before day 1. This talk will go through the journey of the last 8 years of applying known best security practices to an open source project, including becoming a CVE Numbering Authority, and forming a PSIRT team from volunteers from different companies. This team has been managing embargo windows, bulk vulnerability reports as well as the occasional vulnerability reported from the community. It is possible for open source projects to follow Security Best Practices and this talk will let others leverage the key lessons that Zephyr has learned over time. Learn more.
Tuesday October 29, 2024 14:50 – 15:30 JST: Secure and Encrypted Boot in Zephyr RTOS – Parthiban N, Linumiz
MCUboot enables secure booting of Zephyr RTOS using asymmetric cryptographic signature verification with a public key. Typically, the hash of the public key is embedded within the MCUboot binary, ensuring its integrity. For enhanced tamper protection, this hash can also be securely stored and retrieved using hardware keys. Embedded SoCs, such as the i.MX RT, offer advanced security features like High Assurance Boot (HAB), Data Co-Processor (DCP), and Trusted Firmware-M (TF-M) for implementing TrustZone in SoCs like the nRF91. These features enable secure storage with hardware crypto acceleration or external security modules (e.g., TPM, EdgeLock) to store keys in a hardware vault. This presentation will explore MCUboot secure booting with hardware keys, using the NXP i.MX RT as an example. We’ll delve into HAB for booting signed and encrypted MCUboot, establishing a hardware root of trust, and booting Zephyr RTOS using keys from OTP for verification. Additionally, we’ll discuss using the TF-M backend and OTP for securely booting TrustZone-enabled SoCs. Learn more.

Developing with Zephyr: Introduction – powered by Zephyr Project
March 11, 2025; 11:00 am – 11:30 am
What’s in a Name: Is Zephyr Really (Just) an RTOS? Benjamin Cabé, Developer Advocate, Zephyr Project
What more and more people now simply call “Zephyr” is officially branded as “Zephyr RTOS”. But is it really _just_ an RTOS? Zephyr offers more than just an RTOS kernel; much like it would be unfair to compare the Linux kernel to a full-blown distribution such as Ubuntu or RHEL, Zephyr provides a complete embedded development platform that greatly simplifies the development of portable, hardware-agnostic applications. We’ll explore some of the unique features Zephyr offers that are key to enabling productive development, such as its testing framework, its module and dependency management system that greatly simplifies the provisioning of development environments, and more. If you’re already using Zephyr, this session will help you discover some hidden gems you might have missed. And if you’re still considering Zephyr,we’ll help you see the bigger picture especially if you’re maybe focusing on the “real-time” aspect too much without considering the broader ecosystem.

From Code to Current: Reducing Energy Consumption in Zephyr Device Drivers, Fabian Plug, grandcentrix
When designing battery-powered sensor devices, optimizing the power consumption of all components is crucial. While many sensors offer low-power modes, the generic sensor interface in Zephyr may not always utilize these modes efficiently. In this talk, I will provide an in-depth look at how Zephyr’s Power Management Subsystem works, how to integrate it into your device drivers, and how it can be used to further reduce power consumption. Using examples such as a battery level sensor and I2C sensors, I will demonstrate various strategies to manage and minimize a sensor’s energy usage. There are multiple approaches to integrating power management within the Zephyr operating system, and I will discuss how sensor characteristics influence which method results in longer battery life. Achieving optimal energy efficiency requires careful consideration of several parameters. Additionally, I will cover how to accurately capture power consumption data, explaining why conventional tools like multimeters may not be suitable for this task. Finally, based on the collected data, I will infer device usage patterns and validate the effectiveness of the power management implementation.

Porting a Bluetooth Application to Zephyr OS – Benefits and Challenges,David Egan, Infineon Technologies
The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained and embedded systems: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications. Zephyr provides product developers with a software platform that enables re-use of software while keeping the toolchain the same. Once Zephyr OS supports a particular wireless MCU and Bluetooth controller, everything else is abstracted, so software written for Zephyr is hardware agnostic. This paper examines the challenges and benefits of migrating a Bluetooth application to Zephyr OS and supporting it in the future. It also looks at the reasons why the Zephyr environment and development flow might be selected for a project, considering the pros and cons. The main section of the paper chronicles a developer’s journey, starting with setting up a Zephyr development environment and then moving on to porting an existing Bluetooth LE application. It describes the challenges faced and how any challenges are addressed along the way. The resulting paper is a guideline for developers who wish to adopt Zephyr OS for their Bluetooth application.

Level up your Embedded Testing Game – Fretish, Robot and Twister: A Dream Team, Christian Schlotter, Carl Zeiss Meditec
Developing embedded software for regulated environments like medical devices presents unique challenges. Crucially, we need to document how the software design fulfills stated product requirements. While functional testing remains dominant for verifying functional suitability, deriving and maintaining effective test suites can quickly become cumbersome. This talk explores a novel approach to this longstanding problem. We leverage NASA’s FRETish method for formally capturing requirements. We will talk about how the formal nature of FRETish requirements allows for automatic test case generation leveraging the Robot Framework. The latter was specifically chosen as it is partially supported by Zephyr’s test harness today and allows to utilize twister for automated test execution of these test suites on real hardware. This method has the potential to streamline testing, offering benefits such as reduced time and maintenance efforts as well as accurate coverage metrics from very early on in the project’s lifecycle. We’ll discuss our progress in implementing this approach, the challenges we encountered, and potential solutions for deeper integration with the Zephyr project.

Rapid Deployment of IoT Infrastructure on Standards-based SOMs and Open-source Software, Darrio Freddi, SECO
Time- and resource-limited IoT organizations must choose between investing in building their own IoT monitoring and management infrastructure or creating value for their customers and the market. Licensing off-the-shelf IoT platforms can accelerate time to market and give development teams space to produce valuable applications from connected device data. However, these platforms can be limiting in the context of specific application requirements, and also subject entire deployments to vendor lock-in.
Now, commercial IoT monitoring and management platforms derived from open-source software components are helping vertical solution providers overcome make versus buy tradeoffs. By combining open-source software like the Zephyr RTOS in endpoints with Yocto Linux in northbound infrastructure, these platforms give IoT organizations:

Increased deployment velocity
Design freedom and deployment flexibility of open source
Architecture-agnostic hardware compatibility for virtually any edge use case

This session discusses IoT device management and monitoring platform challenges by comparing open-source-derived IoT monitoring and management solutions to off-the-shelf alternatives. It goes on to demonstrate their development and deployment advantages when paired with standards-based COTS edge hardware by highlighting an end-to-end smart vending use case where cloud-based AI makes decisions based on fleet device data over an open, secure, and end-to-end infrastructure.

Navigating the Software Ecosystem for Software-Defined Vehicles: A Multi-OS Architecture Approach, Himanshu Pande, Wind River
As the automotive industry transitions from distributed function-specific systems to centralized computing and software-defined vehicles, a range of operating systems is required to meet diverse and often conflicting needs. Linux and Android, with their flexibility and proven track records in numerous industries, are set to play a key role in future vehicle platforms. However, as vehicle manufacturers deploy applications with increasingly stringent requirements — safety, security, performance, predictability — a more nuanced approach to software architecture is necessary. Real-time operating systems (RTOS), optimized for deterministic latency, will remain essential for safety-critical use cases. In addition, lightweight execution environments like Zephyr offer scalable solutions for constrained devices, while AUTOSAR continues to provide a standardized framework for ensuring interoperability and compliance in embedded automotive software. Together, these components — Linux, RTOS, Zephyr, AUTOSAR, and Android — must complement each other to form a cohesive in-vehicle software architecture that meets the demands of modern automotive innovation. In this presentation, we will adopt the perspective of a software architect, show when and why to use these different solutions, their benefits and limitations, how to combine them (e.g. using modern hardware, virtualization) and how this could apply to other industries.

Cyber ​​Resilience Act Summit
2025-10-13 - 2025-10-14
With the Cyber ​​Resilience Act (CRA), the European Union has established a minimum level of cybersecurity for all connected products. The CRA covers all products sold in the EU that contain “digital elements.” This includes the entire spectrum of embedded systems —from consumer electronics and household appliances to complex high-end industrial systems—if they can be connected to a network or even to another device.
The CRA has been in force since the end of 2024, and implementation must be completed in several steps by the end of 2027 at the latest. Embedded systems developers, as well as project managers and product managers, are therefore asking themselves: How do I proceed to ensure that my products meet the CRA requirements?
At the Markt&Technik CRA Summit, top-class speakers will demonstrate which strategies can be used to make embedded systems of varying complexity “CRA-safe.”
At the event, Zephyr Project’s functional safety expert Nicole Pappler will be giving a talk on “Preparing open source projects for the CRA”.
About the talk: With the entry into force of the EU Cyber ​​Resilience Act (CRA), manufacturers of connected products face new regulatory requirements for cybersecurity across the entire product lifecycle. The Zephyr project, an open-source real-time operating system (RTOS), addresses these requirements through targeted technical and organizational measures.
The key elements include:
Automated creation of software bills of materials (SBOMs) for transparent component tracking
Long-term security support (LTS) with regular vulnerability fixes
Integration into CVE award processes for structured security communication
Vendor-neutral governance and community-driven development that promotes industrial adoption
Zephyr thus provides a robust open source foundation for the development of secure, auditable, and CRA-compliant embedded systems.

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

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.

LF Energy Summit Europe 2026
2026-09-15 - 2026-09-16
Grid operators have to deliver affordable, reliable, safe, clean energy, and they need digital infrastructure to do it. Across the sector, utilities and vendors are increasingly turning to open source as the proven way to co-develop the shared, non-competitive building blocks required to modernize the grid faster, at lower cost, and without dependence on single-vendor roadmaps.
LF Energy Summit Europe convenes utilities, grid operators, technology vendors, energy companies, policymakers, researchers, and practitioners to showcase how open source is being used today to build production-grade digital infrastructure for energy systems. The event highlights recent project developments, emerging innovations, and practical lessons from organizations shipping real code, not just ideas.
Attendees will gain insight from leading experts and practitioners into best practices, tools, and technologies; learn how to participate in and scale open source communities; and connect directly with the peers and leaders who are developing the digital grid together.
If you are working with Zephyr RTOS in energy-related use cases, this is a great opportunity to join the conversation—submit a talk proposal and share your insights with the community.
Submit your talk proposals soon. CFP Closes on Monday 25 May at 11:59 PM CEST (UTC+2) / 2:59 PM PDT (UTC-7)
