The Zephyr Project

Zephyr RTOS 4.2 is out! The latest release brings: ✅ USB Video Class support (UVC) – turn Zephyr devices into webcams or smart cameras ✅ Initial support for Renesas RX MCUs ✅ New Twister power harness to validate power budgets ✅ MQTT 5.0 support ✅ 96 new boards (RISC-V, WCH, Bouffalo Lab & more!) ✅ Zbus reaches stable API ✅ Devicetree tooling improvements ✅ Board catalog now includes shields ✅ Reminder to upgrade to SDK 0.17.2 Check out the full blog by our developer advocate Benjamin Cabé: https://hubs.la/Q03y9V110 #opensource #ZephyrRTOS

From day one Linaro has helped shape The Zephyr Project - the opensource #RTOS for resource-constrained devices. Check out this talk from #LinaroConnect 2025 to learn why Zephyr is a good choice when using #Rust for #embedded development 👉 https://lnkd.in/e9ChjbiK #LIS25 #TBT

At #OSSummit + #ZDS2025 Europe, Andreas Kurz (inovex GmbH) and Stefan Kraus present: CoffeeCaller - a Fully Open Source Product Development Example CoffeeCaller is an embedded device designed to coordinate coffee breaks across a building. What started as a fun idea became an exploration of product development within hobby time and budget. They share the journey from proof of concept to parallel hardware/software development using KiCad and #ZephyrRTOS, modular device tree design, and transitioning from BLE Mesh to openthread.

At #OSSummit + #ZDS2025 Europe, Jaco Liebenberg from Plentify presents a lightning talk: A Reusable Zbus Based Architecture, Abstracting Core Application Components Porting products to Zephyr and a common microprocessor enabled a move toward more reusable code. This talk presents an architectural approach using zbus to create standardized inter-thread communication and a reusable link layer for communication, UI, and system control. The architecture is analogous to micro-services composed of ~5 independent services/modules per application, each interfacing through zbus to maintain modularity and separation of concerns.

We have several Mind delegates attending and speaking at Linux Foundation - #OSSEU2025 in Amsterdam. Titouan Christophe will be speaking at the event about MIDI2 in the real world with #Zephyr (The Zephyr Project). Thomas Perale will be attending as part of our #buildroot efforts due to Mind's maintainership role for the #LTS branch. Charles-Antoine Couret will be attending as well as one of our senior experts. Feel free to send us a DM to get introduced if you have questions about Buildroot, Zephyr, #yocto or other FOSS projects which we deal with on a daily basis. https://lnkd.in/eJmS26T4

The Zephyr Project's Kate Stewart joined Golioth's Chris Gammel to discuss all things related to the Cyber Resilience Act (CRA)... Key dates that should be on your calendar: 📆 June 2026: Government procedures in place 📆 September 2026: Reporting obligations kick in 📆 December 2027: Full regulation in effect Things that will impact your day job: ✔️ 24-hour vulnerability reporting (yes, really) ✔️ Software Bill of Materials (SBOM) required ✔️ 5+ year support periods for security updates "✔️ Secure by design" isn't a nice-to-have anymore Watch the conversation and learn how #ZephyrRTOS can make your life easier → https://hubs.la/Q03BT5gw0 #CyberResilienceAct #CRA #EmbeddedSystems #IoT #Security #Compliance #EUSecurity

📰 Check out my latest blog post on #EmbeddedRelated! I show how to debug The Zephyr Project TSL2591 (light sensor) driver using GDB. 🙌 This blog post describes the work behind my first #pr for #zephyr.
