Diving Into Zephyr's New Hardware Model // Zephyr Tech Talk #014
2024-04-03 15:00 - 16:00 (Europe/Berlin)
Tune in on Wednesday, April 3 (9:00 AM EDT / 3:00 PM CEST) for a new Zephyr Tech Talk live stream where Benjamin and his guests will introduce the new hardware model adopted by The Zephyr Project starting with the 3.7.0 release.
Over the recent years, the world of embedded systems has been evolving at a rapid pace, and the hardware model that Zephyr has been using until recently was no longer able to keep up with the new requirements. SoCs with multiple cores, multi-SoC boards, … are just a few examples of the new features that the old model was not able to handle properly. In this session, where we will be chatting with Carles Cufí, Torsten Rasmussen, and Anas Nashif, you will learn about the new hardware model, the rationale behind it, and, of course, how to migrate any existing board or SoC to the new model (spoiler alert, it’s a mostly seamless process!).
Zephyr Tech Talks are live streams organized by and for the Zephyr community. Join us live to get a chance to ask your questions directly to our guests, or simply catch up the recording anytime afterwards!

Tuesday, April 9:
Join the Hands-On Zephyr Project workshop by Jonas Remmert from Phytec Messtechnik GmbH. This interactive workshop will demonstrate how to set up a development environment and configure an out-of-tree example with Zephyr and cover topics like board abstractions, RTOS features and higher layer software subsystems such as the Sensor API, BLE stack and the networking stack.
Jason Murphy (Co-Authors: David Perez, Wassim Magnin) from Analog Devices will also have a session titled, “Revolutionizing Industrial IoT: Enabling Real-time Secure Connectivity to the Edge with Single-Pair Ethernet and Zephyr OS.”
Single-Pair Ethernet (10BASE-T1L SPE) is transforming low speed, insecure fieldbus installations into flexible, higher data rate links with modern cybersecurity. Running over single twisted pair cabling, SPE enables IP connectivity to field-level devices using existing wiring infrastructure, reducing installation costs while eliminating data islands that commonly exist between operational technology (OT) and IT systems. The shift towards extending IP connectivity to the edge is driving the requirement for
integrating Ethernet connectivity into resource-constrained embedded devices around factories and buildings. This paper explores the use of Zephyr OS as an embedded software ecosystem for Ethernet- connected industrial devices. Zephyr provides a comprehensive networking software stack including support for protocols such as TCP/IP, MQTT and TLS that are crucial software components in industrial IoT (IIoT) applications. We present an overview of SPE technology for IIoT applications, followed by a
discussion on how Zephyr’s software ecosystem can be harnessed to drive rapid development of secure, real-time, Ethernet-connected industrial edge devices. The discussion aims to underscore the potential of Single-Pair Ethernet in combination with modern embedded OS, to drive smaller, smarter, and lower-
cost intelligent nodes deeper into the built environment.
Wednesday, April 10:
Explore the talk ‘Zephyr Project: Result of Applying Open Source Project Best Practices’ by Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation. This talk will delve into the open source best practices that Zephyr has applied over the years, and summarize its current status and outline plans for 2024.
Mohammed Billoo , MAB Labs Embedded Solutions, will also give a talk on the same day on ‘Zephyr Device Drivers: Walkthrough and Examples.” In this workshop, he will offer a deep dive into the Zephyr Project RTOS (or “Zephyr”) device driver model presenting examples of the interesting strategy that Zephyr leverages to incorporate different device drivers, including OS-independent open-source drivers.
Oliver Völckers, BeST Berliner Sensortechnik will give a talk on Enhancing Signal Processing Through Transparent AI in an Embedded Sensor System on the same day. Oliver will give a talk on the innovative approach to enhancing machine learning in distributed IoT systems. The focus of the presentation will be on leveraging transparent rules rooted in human knowledge to address the challenge of acquiring extensive training data, particularly when dealing with sensor data from EDGE IoT systems. The system, operational for nearly two years and actively evaluating wastewater pumps for Deutsche Bahn’s high-speed ICE trains, will be explored in detail. Attendees can anticipate valuable insights into the functionality of the system and its implications for designing distributed IoT sensor nodes for accurate data interpretation.
Thursday, April 11:
Tiago Monte, Developer Marketing Manager at Nordic Semiconductor, will give a presentation about “Building the future of IoT with nRF Connect SDK and Zephyr RTOS.” IoT devices have become more than wirelessly connected gadgets as they continuously incorporate more functionality and sophistication, from security features to multiprotocol, machine learning, and more. This puts increased pressure on embedded software developers to balance development cost, time to market, and maintenance of their products in the field.

In this session, we will discuss Nordic’s nRF Connect SDK, based on Zephyr RTOS, and how it was created from the ground up based on a vision for how to enable developers to build the future of IoT faster, securely, and more scalable.

Zephyr® OS on MCUs: Linux for Micros? | Maidenhead
2024-09-10 08:30 - 15:30 UTC
While Linux has long been predominant in microprocessor (MPUs) based embedded systems, the availability of operating systems for microcontrollers (MCUs) is quite fragmented. Microcontroller manufacturers sometimes have their proprietary offerings, and FreeRTOS has existed for many years. However, not much provides a feature set that is even close to Linux.
Meanwhile, Zephyr® OS has become an option. Semiconductor companies are spending a lot of money and effort to have some of their current microcontroller generations supported by Zephyr. Together with NXP Semiconductors, we would like to invite you to a full-day seminar to discuss Zephyr, what it can do, and how it looks and feels on NXPs’ most recent microcontroller family, MCX through hands-on LABs.
The seminar will cover “traditional MCU development,” which is done by small software teams, usually with the software stack of the MCU supplier. New technologies and the growing complexity of the system context push this model to its limits.

Agenda:

08:30 – Registration / Coffee
09:00 – Welcome and Introduction to NXP MCU Portfolio
09:45 – Zephyr® OS

Introduction
Why Zephyr®?
Coffee break
Zephyr® Ecosystem (Support for ARM Cores, RISC-V, etc.)
LVGL GUI Demo RT1060
Ardunio SIMCom Demo

12:00 – Lunch Break
13:00 – Zephyr® Hands-on LABS using NXP FRDM-MCXN947

Hello World: Import Sample, Build, Debug
Kconfig: Explore and Modify Kconfigs, Guiconfig Tool
Debugging with VS Code: Thread Awareness, Stack Usage, Thread Call Stack
Devicetree: MCUXpresso Device Tree Viewer, Board Overlay Files, Modifying Hardware Configuration

15:00 – Wrap Up / Q&A

New MCU projects must keep up with the increased hardware, software, and protocol complexity. Connecting the system to the Internet introduces another order of magnitude in complexity, as plans for security updates must be considered from the start.
Mustering these challenges in the confines of a software stack originally written by hardware vendors to get users started becomes almost impossible. A larger developer base can share the maintenance load of the “common infrastructure,” freeing developers to concentrate on the features which differentiate their products against the competition. The Free and Open-Source approach is a perfect match for this new landscape.
The cross-architecture, vendor-neutral, and permissively licensed Zephyr® OS is introduced to show how it can help development teams concentrate on product features instead of invisible (yet important!) infrastructure.

Open Source Summit Europe (Vienna, Austria)
2024-09-16 - 2024-09-19
The Open Source Summit Europe, which takes place on September 16-18 in Vienna, Austria, is packed with technical content. It is the premier event for open source developers, technologists, and community leaders to collaborate, share information, solve problems, and gain knowledge, furthering open source innovation and ensuring a sustainable open source ecosystem.
As a conference umbrella, Open Source Summit is composed of a collection of microconferences covering the most important technologies, topics, and issues affecting open source today. Zephyr will be featured as a microconference. Check out the schedule below.
Monday, September 16
15:25 CEST: Bringing Existing Open-Source Code into MISRA Compliance – Roberto Bagnara, University of Parma and BUGSENG – Roberto Bagnara, Professor at University of Parma and BUGSENG
Bringing an existing codebase into MISRA compliance is known to be a difficult, risky and time-consuming task. Yet, when a product needs a functional safety certification and rewriting the software is out of question, this is a necessity. Such an endeavor requires facing multiple tradeoffs and, consequently, lots of experience both on the codebase and on MISRA. The choices between deviating the guideline, and the (often, many) ways in which code may be changed and deviations may be formulated, are tough and with consequences that are not immediately evident. The situation is particularly interesting in the case of open-source software, where additional challenges have to be faced. In this presentation, we illustrate our experience and the several lessons learned while undertaking MISRA compliance work in open-source projects, most notably the Zephyr RTOS and the Xen hypervisor, both used in many embedded systems. Key take-home points include: effective deviation strategies and mechanisms; dealing with the MISRA C essential type model (guidelines related to that account for many of the violations in existing codebases); interaction with open-source communities.
Tuesday, September 17:
9 am CEST: How to Contribute a Zephyr Sensor Driver – Maureen Helm, Distinguished Engineer at Analog Devices
The Zephyr sensor driver API is a popular area for new contributors to submit code upstream; a sensor driver is well-contained, it doesn’t touch more intimidating or complex subsystems, and most importantly, it enables your Zephyr application to interact with the physical world in a new way. Naturally, you want to share it with the open source community, but how do you do it? This talk will share best practices and common pitfalls encountered by new contributors submitting their first sensor driver, and provide insight into why maintainers request certain changes.
09:50 CEST: Zephyr Build System: Sysbuild and New Hardware Model – Torsten Tejlmand Rasmussen, Open Source Software Engineer at Nordic Semiconductor
The Zephyr build system had been reaching its limits in its ability to build multiple images for modern SoCs in its previous hardware model.
The original build system began with the concept of a simple board containing a single core SoC for which you would build a single image. In today’s world however, developers want to build multiple images for boards which may have multiple SoCs and / or SoCs with multiple CPU cores. This evolution towards complexity led us to the development and introduction of sysbuild and a new hardware model in Zephyr.
The purpose of this talk is to dive into the new hardware model, and what it provides seen from a developer’s point of view, and from there continue into sysbuild, where the new hardware model is leveraged in order to build multiple images for a single device. The talk will go over how you as a developer can make the best use of the new hardware model and sysbuild to effectively build a complete project.
11:00 CEST: Secure and Encrypted Boot in Zephyr RTOS – Parthiban N, Software Engineer at Linumiz
MCUboot enables secure booting of Zephyr RTOS using asymmetric cryptographic signature verification with a public key. The hash of the public key is embedded or compiled with the MCUboot binary by default, which is used for checking the integrity of the public key. To tamper-proof, as an alternate secure boot option, the hash of the public key can be stored securely and retrieved when hardware keys are enabled. Security of embedded SoC’s (e.g., i.MX RT) offers more capabilities, such as High Assurance Boot (HAB), Data Co-Processor (DCP), or Trusted Firmware-M (TF-M) implementing the Trustzone for SoC’s (e.g., nRF91) to enable secure storage with hardware crypto acceleration or external security modules (e.g., TPM, EdegeLock) to store keys in hardware vaults.
This talk will detail MCUboot secure booting with hardware keys. NXP i.MX RT as an example using HAB for booting singed and encrypted bootloader MCUboot, enabling hardware root of trust, and booting Zephyr RTOS using keys from OTP for verification. We will also see about using the TF-M backend and OTP for secure booting Trustzone-enabled SoCs.
11:20 CEST: Zephyr Network Subsystem Status and Overview – Jukka Rissanen, Principal Engineer at Nordic Semiconductor
Network connectivity is important part of Zephyr. This talk will give information of current status of the network stack.
11:55 CEST: Lightning Talk: The CFU: Custom Hardware with RISCV and Zephyr – Mohammed Billoo, CEO at MAB Labs Embedded Solutions
RISC-V’s instruction set architecture (ISA) has enabled seasoned embedded software engineers to experiment with FPGAs since numerous open-source RISC-V cores can be flashed onto an FPGA.
The Zephyr Project is rapidly emerging as a leading real-time operating system (RTOS). Zephyr integrates open-source and security best practices to ensure a vendor-neutral, secure, and reliable platform.
One of the exciting features of the RISCV ISA is the Custom Function Unit (CFU), which enables a framework to support custom operations in hardware, which is accessible from software. In this talk, Mohammed will demonstrate how to add a CFU into a RISCV core on an FPGA, and how to make the appropriate calls from Zephyr.
12:05 CEST Lightning Talk: Zephyr Portability with an AI Application on Very Different MCUs – Ales Ryska, Systems Engineer at NXP
Code portability is one of the compelling benefits of adopting Zephyr. In this session we will discuss a single AI-based face detection application that scales from a high performance, Arm Cortex-M7 based MCU to a low power Cortex-M33 based MCU with a neural processing accelerator. In addition to different main processor cores, these two platforms have quite different camera and display interfaces, and one has a limited frame buffer capability, leading to required improvements in the display driver which NXP has contributed back to the project. This session will also explore the specifics of how devicetree and Kconfig were leveraged to switch between platforms.
12:15 CEST: Lightning Talk: Using Zephyr to Power the Sustainable Cloud – Dan Kalowsky, Firmware Engineer at Ampere Computing
Share how Ampere Computing uses Zephyr to re-imagine the cloud in a more sustainable way. Covering some of the challenges encountered aligning product goals with Zephyr, adding new code coverage beyond the upstream support, and getting a test environments up and running.
12:25 CEST: Lightning Talk: Implementing the Precision Time Protocol (PTP) in the Zephyr Project – Adam Wojasiński, Software Engineer at BayLibre
In order for highly distributed communication to function well, there must be a reliable time source and a way to synchronize time between devices. In applications such as automotive and industrial control, the requirements here can be strict and subject to regulatory constraints. Precision Time Protocol (PTP) is a response to these hard time synchronization requirements by achieving clock accuracy in the sub-microsecond range.
As Zephyr becomes more broadly used in these environments, it needs support for precision timekeeping. This talk will cover a brief overview of PTP, discussion of various implementation choices for Zephyr, challenges along the way and upstreaming plans.
14:00 CEST: Developing Wildlife Camera Traps with Zephyr RTOS – Alex Bucknall, Software Engineer at Arribada Initiative
Monitoring wildlife and environmental changes often requires deploying remote camera traps that can capture imagery and activity over long periods of time. These camera systems need to be low-power, portable, and easily adapted to different hardware configurations based on project requirements.
This talk will cover how we utilised Zephyr to develop flexible time lapse camera solutions for conservation applications. We’ll explore our time lapse camera deployment in Bermuda and how we’re using Zephyr to monitor and understand the impact of seagrass decay on the local marine life. Zephyr allowed us to rapidly target different hardware platforms by abstracting away complex hardware interactions. We’ll discuss how Zephyr’s hardware and driver APIs simplify peripheral access to cameras, RTCs, and power management features across multiple vendor SoCs.
Additionally, we’ll explore challenges associated with this kind of cross-platform support, such as lack of core features for certain vendor SoCs. We’ll also share insights into optimising for size, performance, and battery life on constrained embedded devices.
14:20 CEST: Exploring the Potential of Zephyr in Automotive and Software Defined Vehicles – Philipp Ahmann, Sr. OSS Community Manager at Etas GmbH (BOSCH)
In the automotive industry more than 100 embedded control units (ECUs) are present in a typical car. They are equipped with microcontrollers responsible for various peripherals within the vehicle. Although it may be challenging to adapt automotive-specific interfaces to an IoT-driven RTOS like Zephyr, the use of standard peripherals such as GPIOs, I2C, and UART can lead to significant synergies with other products.
However, as starting point, the talk will delve into the automotive specific requirements and technology stacks necessary for integrating Zephyr into automotive development. Additionally, it will highlight areas where Zephyr may not yet be a perfect fit for automotive applications. Key touchpoints for discussion will include the compatibility of Zephyr with established automotive standards like Autosar, COVESA VSS, and CAN stack. Furthermore, the talk will address the challenges related to process compliance and adherence to safety integrity standards in the automotive industry.
This talk aims to initiate a discussion on the potential wider adoption of Zephyr in automotive products and to foster an engaging discussion among industry professionals.
14:55 CEST: Lightning Talk: Open Source Fleet Management in Zephyr – Maciej Sobkowski, Software Engineer at Antmicro
Complex, real-life embedded system deployments often consist of multiple SoCs/MCUs running a mix of OSes, ranging from user-facing high-end nodes based on Linux/Android to MCUs dedicated to controlling specific low-level functions of the device, using an RTOS like Zephyr. Over-the-air updates for such systems poses a challenge, as the firmware needs to be updated in a safe & coordinated way.
Remote Device Fleet Manager is a permissively licensed, fully open source and self-hostable framework for modular, configurable OTA updates, fleet management and ML data management that supports Linux, Android, and, since recently, also Zephyr-based platforms.
This talk will delve into how RDFM was extended to support Zephyr-based systems, the motivations and considerations of the development and some interesting use cases it enables. RDFM allows for fully redundant updates, incl. rollback to the previous version, grouped device updates and mixed OS deployments.
To enable tight interoperability with Zephyr’s ecosystem, the integration is based on the MCUmgr library, communicating with Zephyr devices via the SMP protocol. The MCUboot bootloader is used for managing the firmware on the device.
15:05 CEST: Lightning Talk: Delta Firmware Over The Air (DFOTA) Update: Optimizing Device Updates in Zephyr – Romain Pelletant, Embedded Software Enginner, & Clovis Corde, Embedded Software Engineer at Kickmaker
Firmware Over The Air (FOTA) updates are a well-established method for updating devices, but this approach shows its limitations in the embedded world. Indeed, in embedded systems we have 2 main constraints (among others) when discussing firmware updates : memory and bandwidth. Regarding memory, developing a low-memory-footprint API was our priority when creating this solution. To explain how we built this API, we will discuss compression algorithms and justify our choice of implementing in Zephyr the open-source library “Heatshrink” which is ideally suited for DFOTA’s needs and for embedded systems in general (we can demonstrate the memory footprint differences compared to the already implemented compression algorithm “LZ4”). Next, we will see how deltas (or patches) between two firmware versions are generated (we could present a benchmark to illustrate the data savings achieved by sending patches instead of the full firmware, as it is done during FOTA update). Further, we will explore the implementation of the DFOTA API to explain how it works and how it can be implemented into your project.
15:15 CEST: Lightning Talk: How to Create an Asset Tracker With Zephyr and Thingsboard In No Time – Tobias Marquardt, Embedded Software Engineer at grandcentrix GmbH
In this lightning talk I’ll show you how to create a working PoC of an asset tracker with very little effort by using Zephyr. It’s based on an off-the-shelf cellular SoC that sends GPS data over CoAP to the open source Thingsboard IoT cloud platform.
15:25 CEST: Lightning Talk: From Ideas to 3 Firmwares Powering Railway-Infrastructure Monitoring in 2 Years – Tobias Meyer, Software Firmware Developer at Konux GmbH

Using Zephyr OS, we successfully developed three firmware versions in under two years, establishing a scalable wireless sensor network for enhanced railway infrastructure monitoring.
This talk will detail the rationale behind our technology selections, including Zephyr OS, BLE, LTE-M, and AWS Iot Core.
We will discuss specific features of Zephyr that facilitated rapid development and the aspects that presented a learning curve. Our session will explore critical design decisions, architectural frameworks using Zephyr, and effective strategies for MCU communication and optimizing battery life. It will show how projects are setup, dependency are managed using west, how firmware is tested, and which features of zephyr we use where. We’ll also share common pitfalls and practical lessons learned.
Concluding with recent Zephyr updates and our reflective insights, this presentation will end with what we would have done differently this time.

16:00 CEST: Preparing Zephyr for Safety Element out of Context Certification – Nicole Pappler, Senior Safety Expert at AlektoMetis.com
Zephyr, as also other open source projects, is heading towards functional safety, to achieve a safety certification as a Safety Element out of Context (SEooC) the question of what this really means comes up quite often.
There are usually three stakeholders in a project like project community, the assessor and the user, who actually wants to use the certified software
As all these parties have different expectations of what this certification will require, there are a lot of different rumours and opinions out there regarding functional safety certification. This talk will give an introduction to what qualification evidence is usually prepared and assessed for a SEooC certification, what this means for the project and how it can actually be integrated into a safety relevant software system.
This talk will also give an update of the current status of the safety working group, how to participate and what to expect there.
16:55 CEST: Level Up Your Embedded Testing Game: FRETish, Robot, and Twister: A Dream Team – Christian Schlotter, Software Architect at Carl Zeiss Meditec AG & Tobias Kästner Bridle Maintainer at TiaC Systems
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.
17:45 CEST: Zephyr LPWAN: Connectivity Options and When to Choose Them – Jordan Yates, Co-Founder and Head of Engineering at Embeint
Developers are spoiled for choice when it comes to Low-Power Wide-Area-Network technologies, which can make it difficult to choose where to focus your time when starting a project.
In this session we will run through the advantages and tradeoffs of the various LPWAN solutions that Zephyr supports out of the box, with respect to power consumption, range, reachability and more.
Technologies to discuss include Bluetooth, WiFi, LTE CAT-M1, LTE NB-IoT, LoRa/LoRaWAN and Thread.

NXP I Zephyr OS on MCUs A Linux for Micros? - Leonberg
2024-09-17 10:00 - 16:00 UTC
While Linux is predominant in microprocessor (MPUs) based embedded systems for a long time, the availability of operating systems for microcontrollers (MCUs) is quite fragmented. Microcontroller manufacturers do have their own proprietary offerings sometimes, and FreeRTOS is there since many years. But not much provides a feature-set which comes even close to Linux.
Meanwhile, Zephyr® OS has become a kind of an option. Big semiconductor powerhouses are spending a lot of money and efforts to have some of their current microcontroller generations supported by Zephyr.
Together with NXP Semiconductors we would like to invite you to a half-day seminar, discussing what Zephyr is, what it can do and how it looks and feels on NXPs’ most recent microcontroller family, MCX. We’re looking forward to welcoming you!

16:00 Closing
New MCU projects have to keep up with the increased complexity of hardware, software, and protocols. Connecting the system to the Internet introduces another order of magnitude in complexity, as plans for security updates have to be considered from the start.
Mustering these challenges in the confines of a software stack originally written by hardware vendors to get users started becomes almost impossible. A larger developer base can share the maintenance load of the “common infrastructure,” freeing developers to concentrate on the features discriminating the products against the competition. The Free and Open-Source approach is a perfect match for this new landscape.
The cross-architecture, vendor-neutral, and permissively licensed Zephyr® OS is introduced to show how it can help development teams concentrate on product features instead of invisible (yet important!) infrastructure.
