Zephyr at 10: Scaling an Open Source RTOS for the Next Decade - Anas Nashif, Intel

Wednesday October 7, 2026 09:05 - 09:45 CEST

South Hall 2 B (Floor 2)

Over the last decade, Zephyr has grown from a focused open source RTOS into one of the most widely adopted platforms for connected, secure, and portable embedded systems. That success brings new challenges: more architectures, more boards, more vendors, more contributors, more downstream users, and higher expectations around quality, security, safety, documentation, testing, and long-term maintenance.

This talk looks at Zephyr’s evolution through the lens of project sustainability. It will highlight where the current model is working, where scaling pressure is becoming visible, and what the community needs to address to keep Zephyr healthy for the next 10 years. Topics include maintainer bandwidth, review latency, infrastructure load, test and sample growth, vendor enablement, downstream compatibility, long-term support, security updates, dependency management, and the tension between a unified upstream and the need for product- and platform-specific innovation.

Ten Years of Zephyr: Replace Linux, or Work With It? - Iuliana Prodan, NXP Semiconductors

Wednesday October 7, 2026 11:20 - 12:00 CEST

South Hall 2 B (Floor 2)

A decade after its launch, Zephyr has grown from a small RTOS into a capable, MMU-aware, userspace-supporting system running on application-class cores. So people keep asking: can it replace Linux? A better question is how the two can work together - and Zephyr already has what it needs to do that.

This talk shows how Linux and Zephyr run side by side on the same SoC, using parts Zephyr ships today: the IPC service layer, OpenAMP and RPMsg for messaging between the two cores, mailbox and shared-memory backends, and the mechanisms that let Linux start and stop Zephyr firmware. Based on real work on NXP i.MX and i.MX RT platforms, I'll show how these pieces fit, and where the hard parts are - memory layout, buffer sizes, address translation, and shutdown order.

The takeaway: after ten years, the interesting frontier isn't replacement. It's connecting the two so each kernel does what it's best at on the same chip.

From Reset To Main(): Porting Infineon TriCore AURIX To Zephyr - Parthiban N, Linumiz & Christoph Seitz, Infineon Technologies AG

Wednesday October 7, 2026 13:30 - 14:10 CEST

South Hall 2 B (Floor 2)

Infineon's AURIX family of automotive microcontrollers is based on the TriCore architecture and is widely used across automotive systems, from powertrain and chassis control to safety-critical ECUs. This talk presents the upstream effort to add TriCore architecture support and enable Infineon AURIX TC3x and TC4x devices in Zephyr (https://github.com/zephyrproject-rtos/zephyr/pull/107516).

Starting from CPU reset, we will walk through the key architecture bring-up steps required to reach the first Zephyr thread, including trap and interrupt handling, Context Save Area (CSA)-based context switching, and system timer integration. We will also cover the work required beyond the architecture layer, including SoC support, board enablement, and QEMU-based development and testing.

Finally, we will discuss the challenges of upstreaming a new architecture into Zephyr, from toolchain and CI integration to HAL dependencies and ecosystem support, along with the remaining work needed for automotive and safety-critical systems.

Practical End-to-End Traceability for Zephyr’s Path To Safety Certification - Tobias Kästner & Andreas Kurz, inovex GmbH

Wednesday October 7, 2026 14:25 - 15:05 CEST

South Hall 2 B (Floor 2)

As part of the ongoing effort to achieve IEC 61508 certification, Zephyr's requirements capture process is underway. Yet there is still no clear picture of how these requirements trace to the tests that verify them or the code that implements them. Safety evidence is largely documented evidence, so the primary concern is generating auditable documents: requirement and test specifications, test reports, and traceability matrices.
The challenge is collecting this evidence in a community-compatible way — low-friction processes and tooling that developers and maintainers will accept.

This talk proposes a pipeline built on Zephyr's existing documentation tools (Doxygen/Sphinx) to extract the needed information from annotated source and tests, then trace it back against requirements into an end-to-end chain.
Two demos are shown: a minimal working example against Zephyr itself, and a self-contained pipeline for a Zephyr module the authors maintain. Required process adaptations and guidelines are explained. The work is an open proposal for discussion; once agreed, it gives the community a scalable foundation to advance safety efforts, with concrete tasks contributors can pick up.

AI in Zephyr PSIRT: Lessons From the Front Line - Flavio Vinicius Alvares Ceolin, Hubble Network & David Brown, Linaro

Wednesday October 7, 2026 15:35 - 16:15 CEST

South Hall 2 B (Floor 2)

Zephyr’s security response is run by a small, mostly volunteer team handling a large and growing workload. Every vulnerability report must be triaged against a million-line codebase, confirmed in source, scored, mapped to a CWE, written up as a CVE record, documented for disclosure, and tracked across multiple release branches — often under embargo deadlines that don’t move. It’s repetitive, high-stakes work, and it’s exactly the kind of burden that burns maintainers out.

This talk is a candid look at how we started using AI to help: grounding analysis in the source tree with file:line citations, drafting CVE records against a strict schema to prevent fabricated fields, and reducing release vulnerability accounting from hours to minutes. It covers what worked, what failed, and the guardrails we built to keep a human in the loop. You’ll leave with a practical blueprint and checklist for using AI in security response — and an honest view of where it helps and where it’s still a liability.

CRA Readiness With SPDX 3 SBOMs in Zephyr - Benjamin Cabé, The Linux Foundation

Wednesday October 7, 2026 16:30 - 17:10 CEST

South Hall 2 B (Floor 2)

SBOMs for embedded firmware are harder than simple dependency lists. A Zephyr-based product typically combines upstream Zephyr code, vendor HALs, out-of-tree modules, binary blobs, generated files, Kconfig and devicetree configuration, and of course user/application code. Some of these pieces end up in the final firmware image, some do not, and yet it is important to have a clear picture of what was used, what was changed, and what actually shipped. This is what helps teams avoid chasing false positives, while still knowing when a new CVE might really affect them.

In this talk, we will look at Zephyr’s SPDX-based SBOM generation, including its recently added support for SPDX 3.0. We will show why it is useful to describe not only _which_ components are present, but also _why_ they were pulled into the build and how they relate to each other.

We will also discuss how build-aware SBOMs can directly support vulnerability management and help prepare for regulations such as the Cyber Resilience Act.

Where Zephyr Fits in Space Computer Architecture - Yasushi Shoji, Space Cubics Inc.

Wednesday October 7, 2026 17:25 - 18:05 CEST

South Hall 2 B (Floor 2)

Using Zephyr in space is not only a question of choosing an RTOS. A space computer is a system architecture: boot firmware, supervisor logic, watchdogs, safe mode, recovery paths, update policy, hardware monitoring, FPGA or SoC configuration, and the boundary between platform software and mission-specific applications all matter.

This talk looks at Zephyr from that system-architecture point of view. Based on Space Cubics’ OBC development experience and recent Space Grade Linux discussions, it explores where Zephyr can fit in future space systems: mission RTOS, payload-controller OS, supervisor/control-plane OS, or companion to Linux. Space already has credible RTOS options, but Zephyr can bring value if the ecosystem develops a clear architectural story around boot, recovery, observability, hardware control, and responsibility boundaries.

Attendees will leave with a practical checklist for evaluating Zephyr’s role in a space computer: what Zephyr should control, what should remain outside it, what must be recoverable after launch, and how to structure boot, update, monitoring, isolation, and fault-handling responsibilities.

From TTEthernet To TSN on Zephyr: What Space Systems Teach Us About Deterministic Networking - Yasushi Shoji, Space Cubics Inc.

Thursday October 8, 2026 09:50 - 10:30 CEST

South Hall 2 B (Floor 2)

Many spacecraft avionics and payload systems are already distributed embedded systems: onboard computers, payload controllers, sensors, and links must coordinate under strict reliability constraints. Aerospace has long used controlled onboard networks, from MIL-STD-1553 to Ethernet-based approaches such as TTEthernet. The next question is how open standards such as IEEE Time-Sensitive Networking (TSN) can work in open RTOS ecosystems such as Zephyr.

Based on my experience with TTEthernet, Zephyr, micro-ROS, and space OBC development, this talk asks what TSN on Zephyr should become. TSN is not one feature: traffic shaping, scheduled transmission, redundancy, policing, configuration, time synchronization, and hardware support all matter. Linux already has a mature TSN operations model around user-space tools such as tc and linuxptp. Zephyr has no Linux-style userland, so TSN needs Zephyr-native APIs, shell commands, samples, diagnostics, and management interfaces.

Attendees will learn why TSN matters for Zephyr, why Zephyr cannot simply copy Linux tooling, and what design questions remain for TSN-capable endpoints.

USB Development and Testing on Native Simulator - Johann Fischer, Nordic Semiconductor

Thursday October 8, 2026 13:50 - 14:30 CEST

South Hall 2 B (Floor 2)

Zephyr's new USB support has been in development for some time. It consists of USB device and USB host support. The new device support has been the default for the last two releases. Work on the device part also introduced initial support for the host stack at that time. This was primarily necessary to enable USB/IP support on the native_sim board.

Johann will start with a brief overview of the current status of USB support.

Johann will then present information on virtual device/host controllers and the virtual bus. These are not actually platform-dependent, but they are most often used with native_sim. Furthermore, he will explain how virtual device/host controllers make it possible to build USB applications for native_sim and then export them to a Linux client using USB/IP server support.

Johan will demonstrate that the main benefit of virtual device/host support and native_sim is the ability to test hardware-independent USB code in CI, even on a pull request basis. For example, we can test the behavior of the host/device stack in response to invalid or undefined requests.

Johann will either provide a few examples or point to the samples and specific tests in the repository.

Enabling Matter on Zephyr - Aksel Mellbye, Silicon Labs

Thursday October 8, 2026 15:50 - 16:30 CEST

South Hall 2 B (Floor 2)

Matter is an open-source application-layer connectivity standard for connected home devices built on top of Wi-Fi and Thread, technologies that are both supported in Zephyr. Until recently, Matter support on Zephyr was primarily delivered through vendor-specific downstream SDKs, but there has been a growing effort to collaborate upstream in both the Matter and Zephyr communities to improve integration between the two projects.

This session will explore the current state of Matter support in the Zephyr ecosystem, including how Matter is integrated today as an external middleware module. We will review ongoing development efforts across both projects to create a shared Zephyr platform abstraction layer for Matter, improve build system integration, maintenance and developer experience, and highlight opportunities for community contribution.

Attendees will gain an understanding of the architecture of Matter on Zephyr, recent upstream developments, the roadmap for future integration work, and how they can contribute to the effort.

A Generic RF PHY Driver API for Proprietary Protocols in Zephyr - Sean Lyons, Texas Instruments

Thursday October 8, 2026 16:40 - 17:20 CEST

South Hall 2 B (Floor 2)

Zephyr has mature driver APIs for IEEE 802.15.4, Bluetooth, Wi-Fi, and LoRa but none for radios running proprietary or custom link-layer protocols. The gap is most acute in Sub-1GHz but applies equally to proprietary 2.4GHz radios used in audio, gaming peripherals, and industrial control.
Current workarounds include using a protocol-specific API like ieee802154_radio_api or shipping standalone drivers and importing MAC assumptions that don't belong at the PHY. The result is duplicate code across out-of-tree drivers that lock applications to a single chip and block upstream contribution. The problem spans standalone transceivers and integrated SoCs across TI, Silicon Labs, Microchip, and ST.
This talk revives Zephyr RFC #43201 (closed 2022) with a focused proposal: a new prop_rf driver API covering only physical-layer operations, leaving link-layer concerns to the application or protocol implementer. Three principles drive the design: applications port across vendors without API lock-in; vendor HALs remain free to expose custom features via device-specific extensions; and the API works for both external transceivers and integrated SoCs.

From Zero Hardware To Production: High-Performance Sensors With Zephyr - Jan Germer, Fluke Deutschland GmbH

Friday October 9, 2026 09:05 - 09:45 CEST

South Hall 2 B (Floor 2)

This talk shares practical lessons learned from building multi-platform sensor firmware on Zephyr RTOS for industrial alignment tools. Zephyr enabled our team to deliver a high-quality solution despite an extremely tight project schedule. Early prototyping along with Zephyr’s native simulator (native_sim) enables firmware development and testing long before first PCBs are available. A modular architecture based on message queues and the Kconfig system allows for independent, testable components.
Finally, we dive into the hardware-facing challenges we encountered and solved: deterministic event handling under tight timing constraints and zero-CPU data acquisition using DMA-driven ADC pipelines.
Attendees will gain insights into structuring scalable Zephyr firmware, accelerating development without hardware, and building high-performance embedded systems with confidence.

Some SoCs have an embedded DAC peripheral, which allow to play low or medium resolution audio with minimal electronics, no advanced I2S external codec required.

In this talk, I present a list of ingredients required to make an acceptable audio output:
- The DAC: what it is, how it is different from PWM audio output or I2S peripherals
- DMA, your DAC’s best friend, to run continuously and without drops
- Debug something fast and real-time thanks to tracing

Then I will discuss implementation, with the codec subsystem. Example platform will be ST STM32F7 and Atmel ATSAM3X8E.

Demystifying Pinctrl: Pin Multiplexing in Zephyr - Roy Jamil, Ac6

Friday October 9, 2026 11:05 - 11:45 CEST

South Hall 2 B (Floor 2)

Pin multiplexing is always needed in embedded development. But when we start changing pins in a devicetree overlay, or when creating a custom board, things can quickly become confusing: build errors, wrong pin states, peripherals not starting, or hardware that simply does not behave as expected.

In Zephyr, the pinctrl subsystem is what connects the physical pins of the SoC with the peripherals we want to use. It defines the pin function, the electrical configuration, and the pin states used by the drivers.

In this talk, we will demystify pin multiplexing in Zephyr and explain how to use pinctrl in devicetree in simple words. We will go step by step through pin groups, pin states, common configurations, overlays, board files, and SoC-specific syntax.

We will also use practical examples for common peripherals and vendor families, and show how to debug the most frequent issues when customizing pins.

Measuring What Matters: Introducing Hardware Performance Counters in Zephyr RTOS - Kedareswara Rao Appana, AMD

Friday October 9, 2026 11:55 - 12:35 CEST

South Hall 2 B (Floor 2)

Embedded developers optimizing Zephyr applications often rely on software timers and GPIO toggles—intrusive techniques that alter the behavior they try to measure. Modern SoCs instead provide rich hardware performance counters across the system: CPU PMUs, interconnect/NoC monitors, and memory subsystem telemetry that capture cycles, cache behavior, bandwidth, and contention with near-zero overhead. Until now, Zephyr lacked a unified way to access these metrics.

This talk introduces Zephyr’s new portable **pmu.h** API, a cross-architecture abstraction for hardware performance monitoring. We present the first backend: an ARMv8-A PMUv3 driver that probes counters at runtime, self-calibrates CPU frequency, and maintains per-CPU state using IRQ-locked sequences for SMP safety.

Using real hardware benchmarks, we show how to measure context-switch cost, IRQ latency, cache behavior, branch prediction, and memory bandwidth. Attendees will learn how to add low-overhead profiling to their applications today and how the API will extend to RISC-V HPM, Cortex-M DWT, and SoC-level monitors without changing application code.

Multiple Cores, One Zephyr: The Path To Cortex-M SMP in Zephyr - Sanjay Vallimanalan, Linumiz

Friday October 9, 2026 14:00 - 14:40 CEST

South Hall 2 B (Floor 2)

Multi-core ARM Cortex-M SoCs are becoming increasingly common in today's market. Yet Zephyr RTOS only supports Asymmetric Multiprocessing (AMP) for these devices. The problem with AMP is that it limits true resource sharing, and leaves hardware parallelism underutilized. Symmetric Multiprocessing (SMP) addresses these issues by running a single Zephyr RTOS image with a unified scheduler across all cores. Zephyr RTOS currently lacks support for Symmetric Multiprocessing on ARM Cortex-M based SoCs and hence limits multi-core Cortex-M devices to AMP configurations. This talk presents a Proof-of-Concept implementation of SMP on Dual Core Cortex-M7 cores using the Infineon Traveo T2G (CYT4DN) SoC which runs a single Zephyr image with true parallel execution across cores.

The key framework challenges are: lack of a secondary boot up path for the secondary cores and the complications of unified timekeeping with per-core SysTick timers.

The talk details what has been achieved, the limitations that remain in timeout-driven context switching and scheduling, and outlines a path toward upstream-ready Cortex-M SMP support in Zephyr.

Linux-based Xen Driver Domains are powerful, but they increase the trusted computing base and add complexity to systems that need tight isolation, fast startup, and auditable software components.

This talk updates the Zephyr-based VIRTIO backend for Xen, an effort to run selected VIRTIO backend functions in small, purpose-built Zephyr driver domains. The goal is to preserve Xen’s proven architecture while enabling a finer-grained model: separate lightweight domains for network, storage, or platform-specific services.

Over the past half year, the project has moved toward platform integration. Upstreaming work has progressed, real-hardware demos are being developed on Renesas R-Car V4H, and integration with SoDeV, an SDV platform by Automotive Grade Linux, is underway.

The session will cover the architecture, current upstream status, and obstacles to using it across platforms. Attendees will leave with a realistic view of where Zephyr-based driver domains can reduce the trusted computing base, what challenges remain, and how to contribute to lightweight open-source driver domains for edge and automotive systems.

Zephyr on the Big Core: Real-Time on the I.MX93 Cortex-A55 With Zephyr - Ryan Erickson, Ezurio

Friday October 9, 2026 15:40 - 16:20 CEST

South Hall 2 B (Floor 2)

The NXP i.MX93 almost always gets the same software answer: Linux on the Cortex-A55, an RTOS on the Cortex-M33. But what if you don't need Linux?

Zephyr formally supports the i.MX93 A55 cores upstream (imx93_evk/mimx9352/a55 and /a55/smp), including GICv3 interrupts, PSCI power management, SMP, and the full peripheral set — Ethernet, CAN-FD, USB, MIPI-DSI, and more. Boot time drops, interrupt latency decreases, and memory footprint shrinks. And unlike other RTOS solutions, there are no per-unit royalties.

This session covers two things: first, a technical deep-dive into how Zephyr runs on an arm64 application core and looking at various peripherals and proving they work. Second, a live walkthrough of authoring a Zephyr BSP for the Ezurio Nitrogen93 SMARC — an i.MX93 SOM in the SMARC 2.2 form factor — covering DTS porting, pinctrl, driver enablement, and hardware validation.

Attendees leave with a clear framework for when Zephyr on Cortex-A beats Linux or a proprietary RTOS, and a practical template for porting any i.MX9x board to Zephyr.

From Specification To Merge: Implementing a Standards-Compliant DALI Driver for Zephyr - Sven Hädrich, sevenlab engineering GmbH

Friday October 9, 2026 16:30 - 17:10 CEST

South Hall 2 B (Floor 2)

DALI (Digital Addressable Lighting Interface) is the dominant standard for professional lighting control, yet firmware support for it has been absent from the Zephyr ecosystem — until now. This talk walks through the full journey of designing and upstreaming a DALI low-level driver into Zephyr mainline: from understanding the protocol's precise timing and bus requirements, to crafting an API that fits naturally within Zephyr's driver model, to surviving the community review process through multiple rounds of discussion and refactoring.

Along the way we also experimented with AI-assisted code review as part of our workflow, and we'll share what that was actually like in the context of a real upstream contribution.

We'll be honest about what was hard, what the community pushed back on, and what we'd do differently.
