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!

Agenda:
10:30 Registration

13:00 Lunck break
14:00 NXP MCX Microcontrollers Overview
15:00 Zephyr on MCX
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.

Tuesday October 29, 2024 14:00 – 14:40 JST: Lessons Learned on Following Security Best Practices in Zephyr – Kate Stewart, The Linux Foundation
When the Zephyr project launched in 2016, the lack of standardized security best practices in the IoT market segment was a known problem. It was one of the goals the project wanted to address, and started working on from before day 1. This talk will go through the journey of the last 8 years of applying known best security practices to an open source project, including becoming a CVE Numbering Authority, and forming a PSIRT team from volunteers from different companies. This team has been managing embargo windows, bulk vulnerability reports as well as the occasional vulnerability reported from the community. It is possible for open source projects to follow Security Best Practices and this talk will let others leverage the key lessons that Zephyr has learned over time. Learn more.
Tuesday October 29, 2024 14:50 – 15:30 JST: Secure and Encrypted Boot in Zephyr RTOS – Parthiban N, Linumiz
MCUboot enables secure booting of Zephyr RTOS using asymmetric cryptographic signature verification with a public key. Typically, the hash of the public key is embedded within the MCUboot binary, ensuring its integrity. For enhanced tamper protection, this hash can also be securely stored and retrieved using hardware keys. Embedded SoCs, such as the i.MX RT, offer advanced security features like High Assurance Boot (HAB), Data Co-Processor (DCP), and Trusted Firmware-M (TF-M) for implementing TrustZone in SoCs like the nRF91. These features enable secure storage with hardware crypto acceleration or external security modules (e.g., TPM, EdgeLock) to store keys in a hardware vault. This presentation will explore MCUboot secure booting with hardware keys, using the NXP i.MX RT as an example. We’ll delve into HAB for booting signed and encrypted MCUboot, establishing a hardware root of trust, and booting Zephyr RTOS using keys from OTP for verification. Additionally, we’ll discuss using the TF-M backend and OTP for securely booting TrustZone-enabled SoCs. Learn more.

Developing with Zephyr: Introduction – powered by Zephyr Project
March 11, 2025; 11:00 am – 11:30 am
What’s in a Name: Is Zephyr Really (Just) an RTOS? Benjamin Cabé, Developer Advocate, Zephyr Project
What more and more people now simply call “Zephyr” is officially branded as “Zephyr RTOS”. But is it really _just_ an RTOS? Zephyr offers more than just an RTOS kernel; much like it would be unfair to compare the Linux kernel to a full-blown distribution such as Ubuntu or RHEL, Zephyr provides a complete embedded development platform that greatly simplifies the development of portable, hardware-agnostic applications. We’ll explore some of the unique features Zephyr offers that are key to enabling productive development, such as its testing framework, its module and dependency management system that greatly simplifies the provisioning of development environments, and more. If you’re already using Zephyr, this session will help you discover some hidden gems you might have missed. And if you’re still considering Zephyr,we’ll help you see the bigger picture especially if you’re maybe focusing on the “real-time” aspect too much without considering the broader ecosystem.

From Code to Current: Reducing Energy Consumption in Zephyr Device Drivers, Fabian Plug, grandcentrix
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 cover how to accurately capture power consumption data, explaining why conventional tools like multimeters may not be suitable for this task. Finally, based on the collected data, I will infer device usage patterns and validate the effectiveness of the power management implementation.
March 11, 2025; 2:45 pm – 3:15 pm
Porting a Bluetooth Application to Zephyr OS – Benefits and Challenges,David Egan, Infineon Technologies
The Zephyr OS is based on a small-footprint kernel designed for use on resource-constrained and embedded systems: from simple embedded environmental sensors and LED wearables to sophisticated embedded controllers, smart watches, and IoT wireless applications. Zephyr provides product developers with a software platform that enables re-use of software while keeping the toolchain the same. Once Zephyr OS supports a particular wireless MCU and Bluetooth controller, everything else is abstracted, so software written for Zephyr is hardware agnostic. This paper examines the challenges and benefits of migrating a Bluetooth application to Zephyr OS and supporting it in the future. It also looks at the reasons why the Zephyr environment and development flow might be selected for a project, considering the pros and cons. The main section of the paper chronicles a developer’s journey, starting with setting up a Zephyr development environment and then moving on to porting an existing Bluetooth LE application. It describes the challenges faced and how any challenges are addressed along the way. The resulting paper is a guideline for developers who wish to adopt Zephyr OS for their Bluetooth application.

Testing Embedded Software With Zephyr, Mohammed Billoo, Embedded Software Consultant – MAB Labs, LLC
Testing should be integral to the software development life cycle, especially embedded software. Embedded software engineers should always consider how they will test their implementation at every stage of the development process. They should establish the necessary testing infrastructure before writing even one line of code. Fortunately, The Zephyr Project RTOS contains an extensive testing ecosystem that embedded software engineers can leverage during development. Zephyr has infrastructure for unit testing and integration testing. In this talk, we will learn why testing is especially important for embedded software development and the tools that Zephyr offers to test during each stage of the development process (such as “Ztest” and “twister”). We will see real-world examples and demos of how to implement testing for a Zephyr application, run the tests, and evaluate the generated reports to understand how well we were able to evaluate our application.
Day 2 – March 12, 2025
Qualifying Safe Embedded Systems
March 12, 2025; 10:30 am – 11:00 am
Level up your Embedded Testing Game – Fretish, Robot and Twister: A Dream Team, Christian Schlotter, Carl Zeiss Meditec
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.
March 12, 2025: 2:00 pm – 5:00 pm

However, this is not a requirement, as a virtualized environment via GitHub Codespaces will be available, providing an accessible alternative for those without a local Zephyr installation. Attendees should bring a notebook to participate fully in the hands-on exercises. This ensures they can follow along with the workshop activities, whether working locally or using the virtualized setup.
Learning Outcomes:
Participants will get a good understanding of the Zephyr Project’s core capabilities, including setting up a development environment and using the
Zephyr Shell for sensor interactions and peripheral bringup. Attendees will gain hands-on experience with I2C and sensor data retrieval, as well as extending applications using ZBus. They will be equipped to develop IoT applications using Zephyr, using both hardware and virtualized environments, thereby enhancing their embedded systems development skills.

Rapid Deployment of IoT Infrastructure on Standards-based SOMs and Open-source Software, Darrio Freddi, SECO
Time- and resource-limited IoT organizations must choose between investing in building their own IoT monitoring and management infrastructure or creating value for their customers and the market. Licensing off-the-shelf IoT platforms can accelerate time to market and give development teams space to produce valuable applications from connected device data. However, these platforms can be limiting in the context of specific application requirements, and also subject entire deployments to vendor lock-in.
Now, commercial IoT monitoring and management platforms derived from open-source software components are helping vertical solution providers overcome make versus buy tradeoffs. By combining open-source software like the Zephyr RTOS in endpoints with Yocto Linux in northbound infrastructure, these platforms give IoT organizations:

Increased deployment velocity
Design freedom and deployment flexibility of open source
Architecture-agnostic hardware compatibility for virtually any edge use case

This session discusses IoT device management and monitoring platform challenges by comparing open-source-derived IoT monitoring and management solutions to off-the-shelf alternatives. It goes on to demonstrate their development and deployment advantages when paired with standards-based COTS edge hardware by highlighting an end-to-end smart vending use case where cloud-based AI makes decisions based on fleet device data over an open, secure, and end-to-end infrastructure.

Navigating the Software Ecosystem for Software-Defined Vehicles: A Multi-OS Architecture Approach, Himanshu Pande, Wind River
As the automotive industry transitions from distributed function-specific systems to centralized computing and software-defined vehicles, a range of operating systems is required to meet diverse and often conflicting needs. Linux and Android, with their flexibility and proven track records in numerous industries, are set to play a key role in future vehicle platforms. However, as vehicle manufacturers deploy applications with increasingly stringent requirements — safety, security, performance, predictability — a more nuanced approach to software architecture is necessary. Real-time operating systems (RTOS), optimized for deterministic latency, will remain essential for safety-critical use cases. In addition, lightweight execution environments like Zephyr offer scalable solutions for constrained devices, while AUTOSAR continues to provide a standardized framework for ensuring interoperability and compliance in embedded automotive software. Together, these components — Linux, RTOS, Zephyr, AUTOSAR, and Android — must complement each other to form a cohesive in-vehicle software architecture that meets the demands of modern automotive innovation. In this presentation, we will adopt the perspective of a software architect, show when and why to use these different solutions, their benefits and limitations, how to combine them (e.g. using modern hardware, virtualization) and how this could apply to other industries.
