Zephyr Workbench is an open source Visual Studio Code (VSCode) extension. The purpose is to provide a "few-clicks" platform to manage Zephyr components. It is designed to simplify and accelerate the workflow for building Zephyr applications by automating the setup process (especially on Windows), importing Zephyr SDK, and managing West workspaces, thereby dramatically reducing the barrier to entry for developers of all levels. Whether you’re launching your first Zephyr project or working on a sophisticated multi-board application, this extension provides intuitive configuration wizards and seamless integration with built'in debugging tools.
Furthermore, Zephyr Workbench ensures reproducible builds and rapid turnaround times while effectively managing the projects. Its integrated one-click flashing and debugging feature that supports most West runners, including OpenOCD, J-Link, PyOCD, STLink, and Linkserver. The tool also offers a visual interface that executes West commands, streamlining the process of managing Zephyr projects from creation to deployment, while also providing easy access to memory reports and configuration tools, SPDX and more.

This talk, based on my presentation at other Open source summit events would focus solely on the use of Zephyr for experimenting with new displays of different sizes and experience with the Zephyr display system. Talk would also cover some new sensor drivers that needed to be written. Highlight would be lessons learned and mistakes made and the hard learnt best practices.
This would draw on our previous experiences in building open source Health hardware and scaling from small wearable device to full fledged patient monitoring and handheld devices and all of them running Zephyr. Emphasis is on the single basic codebase across three different chip vendors.
We will also touch on a bit about Open Source health devices and their significance to the open source community as well as the community at large.

MQTT-SN (MQTT for Sensor Networks) is a lightweight variant of the popular MQTT protocol, designed specifically for constrained devices and wireless sensor networks. It replaces the TCP transport with UDP (or other lightweight transports) and introduces features like topic aliasing and gateway-based architectures to reduce overhead.
This talk introduces MQTT-SN, explains its motivation, and explores how it fits into the IoT protocol landscape. We will also discuss the current state of MQTT-SN support in Zephyr, including security aspects such as DTLS, and how developers can use it in real-world applications.
The device tree is one of the defining characteristics of the Zephyr project. Using concepts borrowed from Linux, along with its best buddy Kconfig, it allows us to leverage the ecosystem to avoid endlessly rewriting the same drivers. It is also one of the most challenging aspects of Zephyr for developers to get their head around as they venture into the woods beyond the “Getting Started” guide. Device trees can contain repeated, redundant information and parameters which are difficult to trace back to their source. On the other hand, the device tree caters to an incredibly wide range of users who might be setting up a single accelerometer or specifying the peripheral mapping for a multi-core SoC. So, is the device tree too complicated, is it just right, or are there other ways to tackle this problem?

Zephyr Twister tool allows to apply data-driven approach in firmware development - with extended test data collection as input for trends visualization, performance impact and root cause analysis, anomaly detection, ML/LLM applications, etc.
This session provides an overview of the recently added Twister features for extended data collection as well as several use cases including Zephyr benchmarks, memory footprint, and test coverage analysis.
It should be interesting and insightful for a wide range of Zephyr practitioners: for vendors dealing with huge amount of test data from their CI pipelines as well as for individual contributors.
This talk provides an in-depth, tutorial-style exploration of memory optimisation within Zephyr RTOS, using Nordic's nRF5340 SOC and nRF7002 WiFi chip in various case studies. By focusing on practical, real-world challenges, the presentation aims to empower developers with actionable strategies for optimizing memory usage in resource-constrained embedded systems.
We begin by clarifying fundamental memory concepts such as flash and RAM, heap memory versus stack memory and differences between static and dynamic allocation. We also going to look at how Zephyr allocates and manages it's memory memory. This foundational overview sets the stage for understanding which parts of the codebase are placed into which memory and what are possible choices of memory optimization.
The presentation then delves into our hands-on experience with the nRF5340, highlighting the increased memory demands posed by the Wi-Fi stack and discussing how to mitigate these challenges. We share specific configuration tweaks, code-level optimizations, and introduce essential memory analysis tools.

Since the 1980s, the MIDI (Musical Instruments Digital Interface) protocol has been the leading standard for connecting digital instruments and controllers in live performances and digital audio workstations. In the last 5 years, a brand new revision of this protocol has been released, supporting multiple transports that adapt it to the modern world of high-speed bidirectional communications.
In this talk, we will first look at an overview of the MIDI2 protocol, what it improves on the former MIDI (1) version, how to define its topology, and what kind of data it conveys. We will then dive into practical considerations for developing a custom MIDI2 device, using Zephyr as an example development platform considering:
- USB-MIDI2.0
- Network MIDI2 (UDP based)
- Universal MIDI Packet (UMP) Endpoints discovery and dynamic configuration
Titouan is an embedded and backend developer who worked in remote railway vehicle monitoring and automated visual quality control for the manufacturing industry. He's been using FLOSS and contributing occasionally.
In this session, we will explore the audio stack and frameworks available in Zephyr, with a particular focus on Sound Open Firmware (SOF) - an open-source audio digital signal processing (DSP) firmware and SDK that provides essential infrastructure and tools for audio and signal processing development.
With the release of SOF 2.0, the project has integrated Zephyr RTOS, simplifying and improving its codebase. However, SOF remains tightly coupled to a Linux host OS driver, making it primarily suited for MPUs.
This talk will dive into decoupling SOF from Linux to enable standalone operation on MCUs, making it the go-to audio framework for Zephyr.
Key topics will include:
• Replacing Linux-based host communication
• Modifying SOF firmware to run without Linux-driven configuration
• Leveraging Zephyr drivers for hardware control
Join us to discuss the next steps in making SOF a truly Zephyr-native audio framework.

There is currently an urgent need for companies to reduce and eventually eliminate software-based memory safety vulnerabilities from their product lines. This requirement begins with the underlying operating systems and extends to the applications that depend on them.
This talk will advocate that now is the right time for the Zephyr operating system to embrace an emerging new hardware architecture extension called CHERI (Capability Hardware Enhanced RISC Instructions) to protect its software and applications against memory vulnerabilities from being exploited.
The CHERI technology has a development history spanning nearly 15 years and is backed by the recent formation of the CHERI Alliance - a consortium of businesses (including ARM, Google and Microsoft), academic institutions, and government organisations.
The talk will provide a summary of the CHERI technology, the latest developments, and the work being done to provide CHERI-RISC-V architecture support for Zephyr.
