Running Zephyr in a Light Bulb - Alexandre Bailon, BayLibre

Monday August 25, 2025 09:55 - 10:35 CEST

D203

For many years, we have seen more and more connected devices entering our homes. In most cases, these devices run closed source software, which relies on cloud servers to work and is not always respectful of our privacy.

Alexandre Bailon, who is not really satisfied with the current offerings, has been looking for an alternative using Zephyr.

He has taken an existing device and developed a Zephyr firmware for it. He will present the technologies already available or in development to build a connected light bulb using Zephyr which should be more robust, secure, and respectful of privacy.

Zephyr Workqueues: How They Work and Queue - Loic Domaigne, Doulos GmbH

Monday August 25, 2025 11:20 - 12:00 CEST

D203

Zephyr provides workqueue, a mechanism used to offload non-urgent processing to a lower priority thread. Workqueues are typically found in ISR (interrupt service routine) and high-priority threads.

In this talk, we shall present:
- what workqueues are, and what they are not,
- their typical use case
- how workqueues, scheduling and meta-IRQ threads relate,
- some best practices to address some common challenges, like sysworkq bottleneck, passing data or handling cancellation
- some lesser known workqueues, like the p4_wq

This is a practical hands-on talk. We’ll therefore run demo code and investigate what’s going on under the hood by looking at the Zephyr internal implementation! This will help us to get a solid understanding of workqueues, their usages and limitations, “directly from the source” (code).

Video4Zephyr: From Basic APIs Towards a Full-fledged Video Subsystem - Phi Bang Nguyen, NXP Semiconductors

Monday August 25, 2025 16:30 - 17:10 CEST

D203

Originally introduced in 2019, the Video4Zephyr (v4z) APIs provided a foundational interface for interacting with video devices in Zephyr. However, with minimal changes over the years, their limitations have become apparent—especially as video hardware grows more complex and camera-based applications become increasingly demanding.

This talk presents the current status of v4z, hightlighting recent improvements as well as sharing ongoing and upcomming works which turns the v4z from a simple driver API into a robust video subsystem. We’ll cover the devicetree video port/endpoint mechanism, a unified video control framework, enhanced buffer management, and support for memory-to-memory (m2m) devices, etc. These efforts aim to shift commont functionality and logic into the subsystem itself, significantly reduce the burden on driver developers - bringing the Zephyr’s video stack closer to a mature multimedia framework.

Mirror and Control Android Phone With Zephyr on I.MX RT1170 - Phi Bang Nguyen & Trung Hieu Le, NXP Semiconductors

Tuesday August 26, 2025 11:00 - 11:40 CEST

D203

Mirroring and controlling a smartphone via a vehicle’s screen enable hands-free access while ensuring comfort and safety. Existing solutions like Android Auto or CarPlay require high-end MPUs and rich OSes. In this talk, we demonstrate a lightweight and low-cost alternative using the i.MX RT1170 MCU running Zephyr RTOS:

https://www.youtube.com/watch?v=EVt0pZxM8Xg

The Android phone captures its screen, compresses it in MJPEG, and streams it to the MCU. On the Zephyr side, we use ffmpeg for video decoding and send touch events to the phone. Despite no hardware decoder, we achieved 11 fps with 100–200 ms latency. MJPEG was chosen over H.264 for its better performance. Upcoming MCUs like the i.MX RT2660/RT2770 with MJPEG/H.264 hardware decoders will boost this further.

We are currently transitioning to Wi-Fi for a fully wireless set-up and offloading camera-based gesture control to the smartphone for hands-free controls. Finally, to inject touch events into Android without root access, the Android application needs to be launched in a shell by ADB from a laptop. We're working on porting ADB to Zephyr to automate this process for a seamless, plug-and-play user experience.

Model-Based Testing for the Zephyr RTOS - Philipp Panzer, UL Solutions

Tuesday August 26, 2025 16:20 - 17:00 CEST

D203

The use of Zephyr in safety-critical domains poses a significant challenge with regard to certification. Since feature development in open-source projects is usually not driven by a centralized requirement specification, V&V become challenging tasks: The lack of a requirement specification makes the subject of validation hard to capture. Verification requires considerable effort for manual test creation. To address these issues, we explore a Model-Based Testing (MBT) approach for Zephyr, which involves the creation of a formal model of the system. Based on this specification, runnable test cases are automatically derived which pass if the actual software implementation aligns with the model. We present our approach of applying MBT to Zephyr's semaphore API, which uses TLA+ and generates runnable ZTest test cases. Given the promising results of our initial exploration, we want to share our ideas with the community to encourage further work in this area. We argue that an integration of MBT into Zephyr’s development cycle results in formal specifications of the system, which, combined with test generation, enable automated conformance testing and facilitate continuous certification.

Zephyr RTOS: Under 1KB of RAM - Parthiban N & Karthikeyan Krishnasamy, Linumiz

Wednesday August 27, 2025 09:50 - 10:30 CEST

D203

On a well-supported hardware platform/SoC, the typical RAM required to run simple applications like hello_world or blinky is around 1.5 KB with the default configurations. SoCs with RAM under 8 KB are common in single-purpose application use cases. With the recent announcement of the world’s smallest microcontroller from TI [1], featuring just 1 KB of SRAM, this coincidentally overlapped with our initial efforts to get the MSPM0 family series into the Zephyr RTOS upstream.

As of today, the smallest RAM where Zephyr can run is 2 KB, supporting UART and GPIO, which utilizes over 90% of the RAM. We often encounter the "FLASH/RAM overflowed by N bytes" error when attempting to get Zephyr working under 1 KB of RAM.

In this talk, we will share the challenges faced while running a useful use case application under 1 KB using Zephyr. Achieving this was made possible thanks to the small footprint of the kernel (i.e., 128 bytes). We will discuss what goes beyond GCC’s -Os and -Oz flags and how we managed to get true multitasking with I2C, SPI, and ADCs running, all while keeping current consumption under 2 µA.

From Code To Current: Reducing Energy Consumption in Zephyr - Fabian Pflug, On behalf of myself

Wednesday August 27, 2025 11:00 - 11:40 CEST

D203

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 compare different MCU's and their influence on Power consumption and how Zepyhr enables a quick and easy way to switch and compare results on different platforms.
