Tuesday, December 6
2-2:40 pm: Implement Safety with a RTOS Running as a Linux Companion Within the Same SoC – Stephane Desneux, CTO, IoT.bzh
Even though significant efforts attempt to prepare Linux for safety certifications, it seems obvious that these initiatives cannot deliver before years, if not decades, due to the magnitude of the work remaining. However, at the same time, the global automotive industry must comply today with many new certifications, including for cybersecurity (UNECE R155) and Over-The-Air software updates (UNECE R156) as well as those existing for safety (ISO-26262). This talk offers a pragmatic approach by leveraging existing hardware platforms and modern OSS software patterns to solve (partially!) certification issues related to safety, real-time and cybersecurity. This approach includes (but is not limited to) a small companion OS running within the same SoC (like Zephyr, FreeRTOS or AutoSAR) to perform certain critical functions. It also tries to use the latest techniques in containers and software isolation to satisfy security, privacy and safe updatability. Add it to your schedule here.
4-4:40 pm: Zephyr RTOS: Applying Open Source Best Practices – Kate Stewart, Vice President of Dependable Embedded Systems, The Linux Foundation
We need to bring the quality and security best practices from open source development of clouds and desktops to resource-constrained devices. Since its inception in 2016, the Zephyr RTOS project has been a leader in applying known open source development best practices.
We’ll go over some of the key strategies adopted in the last 6 years, that have resulted in Zephyr being used widely in products in multiple market segments such as wind turbines, computers, hearing aids and more. These best practices for software quality, transparency, traceability & supporting security are now making it possible to aim for safety-critical applications as well. Add it to your schedule here.
4:50 – 5:30 pm: Asymmetric/Heterogeneous MultiProcessing (AMP/HMP): Mainline Linux and Zephyr in Unison – Marcel Ziswiler, Software Team Lead, Toradex AG
This talk is a deep dive into the AMP/HMP topic showing both the Cortex-A as well as the Cortex-M4/M7 side of things. The first part looks at the various options how to actually launch code at various stages throughout the lifetime of a system, be it directly from a boot container by the boot ROM, later by the boot loader using U-Boot’s bootaux command or once Linux is booted on the Cortex-A core using the remote processor framework (remoteproc). How mainline Linux and Zephyr work in unison is covered in the second part by further discussing concepts like the remote processor messaging (rpmsg) framework using the virtio-based messaging bus which allows kernel drivers to communicate with remote processors available in the system. The third part looks at the communication library landscape where the likes of OpenAMP and RPMsg-Lite are covered. My talk is mostly SoC agnostic but concludes with a real-life demo using NXP i.MX 7/8M Mini and 8M Plus-based systems running the fully open-source software stacks previously introduced. A similar presentation was held at the Embedded Linux Conference in Austin in June.

It is the gathering place for open-source code and community contributors.
Open Source Summit is a conference umbrella, composed of a collection of events covering the most important technologies, topics, and issues affecting open source today.

On Wednesday, May 10 at 12:05 – 12:45 pm: Reproducible Multi Element System Composition with Linux, Xen & Zephyr – Philipp Ahmann, Robert BOSCH GmbH

Looking at system architectures for complex safety-critical systems, similarities can be observed across various industries. Beside a rich OS (such as Linux), typically an RTOS and virtualization or containers are involved. However, when it comes to prototyping such systems, the existing guidelines are limited and reproducing demos is hard and time consuming. Compared to traditional (safety-critical) systems, created by strictly following the v-model, existing open source software can boost the system creation & understanding by fast and iterative prototyping. The ELISA project’s systems working group focuses on creating such an exemplary system architecture using Linux, Xen and Zephyr in a reproducible form. This includes step-by-step documentation for users on different expert levels and various entry points to approach these systems. It also includes picking up new requirements such as a system SBOM and a strong interaction as well as collaboration with other open source projects. Beside the state of the previously mentioned activities, the talk highlights other ELISA working groups focusing on Linux Kernel, processes, tools, and use cases. A basic understanding about challenges and chances of using open-source projects for safety-critical workloads rounds up the talk. Add this to your schedule here.

Webinar: How to run FOTA updates using LwM2M & Zephyr
2023-07-12 11:00 - 12:00 (America/Los_Angeles)
How to run a FOTA update using LwM2M & Zephyr
As more and more resource-constrained IoT devices are being deployed, firmware updates over the air (FOTA) are becoming increasingly important as it provides a way to fix bugs, patch security vulnerabilities or add functionality throughout the lifespan of a connected device.
The Lightweight M2M standard defines the process for remote firmware updates. When following the guidelines provided by the protocol in combination with (open source) SDKs, updating the firmware of resource-constrained devices can be accomplished effortlessly and securely, regardless of the device or platform used.
During this 30-minute webinar, Aleksander Wojtowicz, Embedded Developer at AVSystem, and Laurens Slat, Developer Relations at AVSystem, will explain the process behind remote firmware updates as defined by the LwM2M standard. In addition, a live demo will be conducted using the Nordic Thingy:91 devkit which runs Zephyr RTOS and connects to Coiote IoT Device Management Platform.

Join Zephyr Project member Memfault for a webinar “Employing Coredumps to Debug your Embedded Devices” on Wednesday, July 26 at 9 am PT/12 pm ET/6 pm CET. Eric Johnson, Firmware Solutions Engineer at Memfault, will give a demo and show examples of coredumps with Zephyr RTOS. Register here.
About the Webinar:
Do you have a memory allocator that needs usage monitoring? Add it to your coredump! Or sensor data that causes a unique stack overflow? Add it to your coredump!
We know firsthand how difficult identifying and solving the root causes of firmware faults is, particularly for devices in the field. Local debugging and logging subsystems are commonly used to determine the issue cause, however, these tools are limited and invasive. This is where coredumps become helpful! Coredumps, an underutilized debugging resource, can provide valuable insights as they contain highly structured data that can be easily parsed.
Attendees will learn how to:

Capture detailed insights into faults with coredumps
Use GDB with a coredump
Utilize Memfault to collect coredumps on any embedded MCU, Linux, or Android devices

Monday, October 16:
11:30 am – 12:15 pm: From an Artificial Nose Weekend Hack to a Future-proof IoT Device – Benjamin Cabe, Zephyr Project Developer Advocate
It was a long weekend of May 2020. Like many of my human siblings stuck at home with time on their hands due to an ongoing pandemic, I was busy trying to perfect my bread recipe. Fast forward to a few hours later, I had assembled an Arduino-based “artificial nose” that used a gas sensor and AI (so-called TinyML) to learn and detect scents (hence potentially the smell of a perfectly fermented sourdough starter).
As I open-sourced and started to share the project on social media, it went viral… and I felt like an impostor, as most of the code powering it was, frankly, hackish. Or maybe it wasn’t, as it had the merit of having helped me invent something new, in literally a few hours.
In this talk I will walk you through some of the key features of the artificial nose, and how I eventually refactored my original codebase to leverage Zephyr (an open-source real-time operating system) in order to make it easier for myself and the community to extend the project, and run it on a variety of hardware targets.
You will learn, among other things:

How to move from a complex “super loop” to well architected threads and event-based programming ;
How to run TinyML models (ex. TensorFlow Lite) while not compromising the rest of your embedded system ;
How to build an efficient and easy-to-maintain graphical user interface ;
How to leverage Zephyr hardware-abstraction layer.

All the code and demonstrations shown in the talk will be available on GitHub, and you are very much encouraged to go ahead and build your own artificial nose after the presentation!

The Linux Foundation Member Summit (Monterey, California)
2023-10-24 - 2023-10-26
The Linux Foundation Member Summit, hosted on October 24-26 in Monterey, California, is the annual gathering for Linux Foundation member organizations.
An annual gathering for Linux Foundation members that fosters collaboration, innovation, and partnerships among the leading projects and organizations working to drive digital transformation with open source technologies. It is a must-attend for business and technical leaders looking to advance open source strategy, implementation, and investment in their organizations and learn how to collaboratively manage the largest shared technology investment of our time.
The Zephyr Project will be represented at the conference in a session presented by Kate Stewart, Vice President of Dependable Embedded Systems at the Linux Foundation. On Tuesday, October 24 at 4:15-4:45 pm, Kate will present, “Enabling UN Sustainable Development Goals: Zephyr Project Contributions.”
Given the Zephyr Project’s focus on being able to operate in resource constrained environments, it’s not surprising that we’re seeing products emerge that help conserve and make better use of this planet’s resources, that are built with Zephyr. This talk will walk through some of the capabilities of the Zephyr project. It will show how the products emerging using it are contributing to the UN Sustainable Development Goals. Add it to your schedule here.

Zephyr will be represented in several sessions and a microconference. All times below are in Eastern Standard Time and the room/timing can change depending on the conference.
November 14 at 4:30 – 5:15 pm: Putting Linux into Context – Towards a reproducible example system with Linux, Zephyr & Xen – Philipp Ahmann, Robert Bosch GmbH
Demos on embedded systems using Linux are plentiful, but when it comes to reproducing them, things get complicated. Additionally, on decent embedded systems Linux is only one part of the system and interacts with real-time operating systems and virtualization solutions. This makes reproduction even harder.
Within the Linux Foundation’s ELISA project, we started to create a reproducible example system consisting of Linux, Xen, and Zephyr on real hardware. This is the next step after we achieved a reproducible system with a pure Linux qemu image.
The idea is to have documentation, a continuous integration including testing, which can be picked up by developers to derive and add their own software pieces. In this way they should be able to concentrate on their use case rather than spending effort in creating such a system (unless they explicitly want this). We also show how to build everything from scratch. The assumption is that only in this way it is possible to get a system understanding to replace elements towards their specific use cases.
We had challenges finding good hardware, tools, freely available GPU drivers and more and we are still not at the end. A good system SBOM is also creating additional challenges, although leveraging the Yocto build system has provided some advantages here.
While we are setting up the first hardware with documentation from source to build to deployment and testing on embedded hardware, we aim to have at least two sets of all major system elements like Linux flavor, a choice of virtualization technique, real-time OS and hardware. Only when software elements and hardware can be exchanged, we identify clear interfaces and make a system reproducible and adoptable.
Open Questions are:

What will be a good next hardware to extend this PoC scope?
Where do open source, security, safety, and compliance come best together?
Which alternative real-time operating systems and virtualization should be incorporated?

Wednesday, November 15: Internet of Things MC (2:30 – 6:15 pm)

The IoT Microconference is a forum for developers to discuss all things IoT. Topics include tools, telemetry, device drivers, and protocols in not only the Linux kernel but also Real-Time Operating Systems such as Zephyr. All sessions will be in the James River Salon A at the Omni Richmond Hotel and all times listed below.
2:30 – 3:05 pm: Linux-wpan updates – Stephen Schmidt
Topics we’ll discuss include:

team maintainership
recent and upcoming features: mlme, beacons, scanning, associations, peers
basic parts for a pan coordinator userspace service
wpanusb generic specification challenges (phy layers, channels, multi-band, hw
offload, …)
link-Layer security and status and problems

3:10 – 3:45 pm: TSCH@Zephyr: IEEE 802.15.4 SubG IIoT in the Making – Florian Grandel, the Zephyr Project Community Member
Zephyr’s native IEEE 802.15.4 L2 is a hidden treasure: It supports a much larger variety of SoCs, vendors and PHYs than its more popular OpenThread counterpart. Native L2 not only runs the common 2.4G O-QPSK modulation but also has rich SubG support on all regional bands, from legacy BPSK all the way to SUN O-QPSK, FSK and OFDM and even initial support for HRP UWB. The latter is increasingly hot as mobile manufacturers converge around 802.15.4z/FiRa for precision UWB indoor localization. When I realized this huge potential I immediately wanted to leverage it for industrial use cases. That’s when the TSCH@Zephyr project was born in late 2022.
TSCH is IETF/IEEE’s open contender to the proprietary WirelessHART standard (and to some extent to ISA 100.11a): a reliable and available wireless (RAW), low-power, deterministic real time protocol, relevant to wireless industrial automation, TSN and distributed battery-driven IIoT sensor networks.
This BoF presents the current state of affairs wrt TSCH, SubG and distributed clocks @ Zephyr. We’ll run through solved and unsolved challenges on the way to support a precision TDMA protocol on Zephyr’s TI CC13/26xx driver, look at related driver API changes and at some of the underpinning conceptual work re precision distributed clocks. The latter are a cornerstone of an embedded RTOS that wants to provide re-usable primitives for all kinds of precision timing applications like ranging, PTP, 15.4 superframes/DSME/LE, TSN/DetNet, industrial ethernet/SERCOS/Profibus/… or the upcoming 5G/6G RAW extensions.
3:50 – 4 pm: Zephyr Retro-and-Prospective: Project Growth, Long Term Support, and Linux Interoperability – Christopher Friedt

Zephyr has been a part of the Linux Plumbers IoT Microconference since the first year in 2019. Needless to say, much has happened in that short period of time.
Increasingly more devices are shipping with Zephyr. More companies are becoming members. More devices and are compatible out-of-the-box with Linux (and macOS, and Windows). The Internet of Things is made of devices both big and small – from Edge devices to The Cloud. Zephyr usage has skyrocketed from personal BLE monitors, to Industrial IoT, all the way to the some of the highest-throughput datacenter accelerators that power The Internet.
While we love to see Linux and Zephyr working in concert, industry collaboration and standards have enabled interoperability with all major operating systems and several Real-Time Operating Systems.
This will be a Lightning-Talk style recap outlining the rapid growth that we have seen, major features added, standards supported, and problems solved, in large part due to you!
We’ll touch on what went great (and not-so-great), provide pointers for developers looking to transition from Zephyr LTSv2 to the up-coming LTSv3, and offer a glimpse into what is on the horizon for the Linux and Zephyr IoT Ecosystem.

4:30 – 5:05 pm: Shared FPU Support in Zephyr for ARM64 and RISC-V – Nicolas Pitre, Baylibre
Computers are good at doing computations, obviously. But this is not that simple when floating point numbers are involved. Many processors implement a dedicated floating point unit (FPU) to perform computations on such numbers much faster compared to using the regular arithmetic logic unit (ALU).
FPU usage is not free though, especially when an operating system is involved whose purpose is to arbitrate resource usage amongst competing computing tasks. The FPU context may be quite large and simply preserving and restoring it across task switches, just like with the ALU context, may represent a significant overhead we want to avoid when possible, especially on an RTOS such as Zephyr. But adding smartness to the FPU context switching does come with its share of challenges and surprises.
In this presentation we’ll quickly review the IEEE754 floating point standard in the context of ARM64’s and RISC-V’s FPU. Then we’ll look in greater details at Zephyr’s FPU sharing support for those architectures, design rationales, as well as some interesting snags the implementation had to deal with.
5:05 – 5:40 pm: Challenges in Device Tree Sync – kernel, Zephyr, U-boot, System DT – Nishanth Menon, Texas Instruments, Inc.
he description of hardware through Device Tree, which includes Firmware in some instances, has become an increasingly common practice in many software ecosystems. However, despite various efforts, the device tree description of hardware has yet to be standardized across different software ecosystems, creating challenges for users, automated tools, and ecosystems.
The objective of this session is to:
a) Share experiences of device tree challenges seen with U-Boot, Zephyr, and kernel in the recent attempts for support of Texas Instrument’s AM625, TDA4VM platforms
b) Rationale and challenges created by the diverse approaches
c) Propose a hybrid approach toward the Zephyr device tree support for TI platforms
5:40 – 6:15 pm: Breaking Barriers: Arduino Core API advancements in Zephyr, Linux and IoT Systems – Dhruva Gole, Texas Instruments, Inc.

This presentation will provide an overview of the Arduino Core API and Zephyr RTOS, and explain how their integration can simplify and streamline IoT development. We will cover the advantages of using the Arduino programming model with Zephyr, and how it can benefit developers by providing access to a wide range of pre-built functions and modules. The presentation will also cover the key features of the Arduino Core API for Zephyr RTOS, including digital and analog input/output, serial communication, and peripheral interfaces. We will discuss how these features can be used to create real-time applications with reduced development time and complexity.
There is still scope to achieve an even more seamless experience for beginners, by integrating it with Platform IO or Arduino IDE. However this approach of how we can tie zephyr, the Arduino core module and platform IO needs to be discussed further, as to what the ideal way to do this would be, and if there are other better platforms to target instead.
We will also explore possibilities as to how one can leverage a Linux Host machine as a CI tool to enable development and testing of an Arduino application code with the help of native_posix target. This can help Arduino Code projects to test and validate their codes faster and in a simpler fashion. No clear way to do this exists today and this too is a topic that could garner some attention.
There is also room for improving the Arduino Core API support to include the SPI, CAN and USB implementations. There’s also an opportunity to leverage the excellent BLE stack in zephyr in an Arduino friendly way using something like the ArduinoBLE compatible calls. The talk will cover a few approaches to tackling these challenges and hope to get better suggestions or reviews from the community.

Tuesday, December 5
10:15 – 10:30 am: Keynote: Building Dependable Systems with Open Source – Kate Stewart, Vice President of Dependable Embedded Systems, The Linux Foundation
By looking at the press headlines, we’ve learned that open source is already being used in market segments (like space, automotive, industrial, medical, agricultural) applications that have safety considerations today. Details about the safety analysis performed are behind NDAs and are not available to developers in the open source projects being used in these products. To make the challenge even more interesting, the processes the safety standards are expecting are behind paywalls, and not readily accessible to the wider open source community maintainers and developers. Figuring out pragmatic steps to adopt in open source projects requires the safety assessor communities, the product creators, and open source developers to communicate openly. There are some tasks that can be done today that help, like knowing exactly what source is being included in a system and how it was configured and built. Automatic creation of accurate Software Bill of Materials (SBOMs), is one pragmatic step that has emerged as a best practice for security and safety analysis. This talk will overview some of the methods being applied in some open source projects (like Linux, Xen & Zephyr), as we try to establish other pragmatic steps when open source projects are used in safety critical. Add this to your schedule here.
5:30-6:10 pm: Zephyr Project: Results from Applying Open Source and Security Best Practices – Kate Stewart, Linux Foundation
When the Zephyr project was launched in 2016, it was just one in a crowded set of open source RTOS solutions available. Since then, it’s become one of the most active real time operating system being used for resource constrained devices with a vibrant and growing developer community. A lot of the lessons learned from the Linux kernel development were applied, but the project chose deliberately to do some things different and adopt some of the security best practices . Zephyr is one of the few open source projects that has a PSIRT team and is an actual CVE numbering authority (CNA). Zephyr has also engaged with a safety certification authority, and is working towards 61508 certification in 2024. This session will review the practices that the Zephyr community has adopted, and what has been working and other lessons learned. Add it to your schedule here.
Wednesday, December 6
11:25 am-12:05 pm: Supporting Hobbyist Friendly OpenSource Hardware in Zephyr – Hiroshi Tokita, Fujitsu Ltd.
Arduino UNO R4 is a super-nova in open hardware. This is cheap, readily available, and it can use many existing options from third parties and communities. We want to use it with the Zephyr. The Raspberry Pi Pico is another popular board in the electro hobby community. It also use in many open hardware project. I started porting the UNO R4 board. I will report the status. Now, Raspberry Pi Pico gets mostly features support in Zephyr. Today, I talk about PIO, the most recently developed and exciting feature in the Pico. The optional module called the “Shield” has played an essential role in the open hardware ecosystem. Zephyr can handle the “Shield” as a standardized connector. I will show the benefits of connector systems in Zephyr and some difficulties and solutions (proposal) in application to Raspberry Pi Pico. Additionally, I will introduce ArduinoCore for the Zephyr project. Arduino was initially designed for non-programmer development. It provides a unique experience for rapid prototyping, but some must be fit for best practices in embedded development. This project supports a gradual transition besides the growth of the project ‘just an (Arduino) sketch’ to ’embedded system development.’ And At last, I will show some attractive cheap boards that has a RISC-V chip. It may provide a different perspective from the chip that Zephyr mainly supports. Add it to your schedule here.

Zephyr Tech Talk #008 - IPC in Zephyr: to Zbus, or not to Zbus?
2024-01-10 15:00 - 16:00 (Europe/Paris)
Tune in on Wednesday, Jan. 10, 2024 (9:00 AM EST / 3:00 PM CET) for a new Zephyr Tech Talk live stream!
As we enter the new year, we are having not one, but two guests on the show! There are many ways to implement inter-process communication (IPC) in Zephyr, and choosing the right one for your use case can be tricky. Are low-level kernel primitives to be preferred for their performance and footprint, or should you be using a higher-level abstraction like Zbus?
Rodrigo Peixoto and Bjarki Arge Andreasen will join Benjamin to debate the pros and cons of each approach. Rodrigo is the author of Zbus and will give us insight into the design decisions behind it and some of the use cases to which it best suits. Bjarki will advocate for some of the lower-level IPC mechanisms available in Zephyr and how it can sometimes be beneficial to use them to leverage the compiler and linker’s ability to check for type consistency, even if that might mean being less generic.
As always, it will be a lively discussion with you, the audience, and the hope is that we will answer the question posed in the Tech Talk’s title with more than the traditional: “it depends!”.
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!

2:30 pm – 2:55 pm: Power to the People – Technology for Access to Energy – Vivien Barnier & Martin Jäger
The world has made great progress in providing everyone with access to energy; however, recently, the number of unelectrified people on Earth has increased. Providing access to energy is a critical and complex challenge as most unelectrified people live in extremely remote and hard-to-reach areas, often having limited mobile network connectivity, unknown (future) demand patterns, and extreme weather conditions combined with very low purchasing power of the affected population. The power of Open Source is still completely underrepresented in technological innovations in this sector. We are working towards improving this situation and will showcase one of our flagship examples: An Open Source Battery Management System (BMS) specifically developed for off-grid energy application. Energy storage and its related technologies are key to any off-grid energy application and the Libre Solar BMS has been specially developed for this use case. We will deep dive into the design decisions and features, covering hardware, firmware and an app. The BMS was developed leveraging solely open source tools: The PCB is designed in KiCad, the firmware runs on Zephyr RTOS and the communication interfaces use the ThingSet protocol over various lower layers like Serial, CAN, WebSocket or MQTT. The hardware went through three design iterations and has been lab and field-tested by several organizations. We will conclude and show why this kind of Open Source technology is of such great importance to bring power to the people in both the sense of bringing electricity literally and also creating the grounds for local value creation in the affected geographies. We invite the whole Energy Open Source community to contribute with their efforts to where the contributions can be most impactful on various levels. The Open Source BMS is one great piece, but we need much more of those.
2:30 pm – 2:55 pm: How open source projects approach Functional Safety – Nicole Pappler & Philipp Ahmann
Open Source is a winning solution for many industries already – and now even safety critical applications want to make use of it. While “security” is a capability of open source since many years, a few years ago using open source in safety critical applications seemed to be impossible even to think about. Nowadays it has become a valid option for upcoming applications. This kind of application that should save lives, or at least not harm anyone. However, with advancements in technology and safety integrity standards, open source is becoming a valid option for upcoming safety critical applications. This talk will provide an overview of how open source projects approach their integration to safety critical applications. Depending on the expectations of these applications, there are different solutions to address their needs. The talk will introduce example projects such as ELISA, the Zephyr Project, and the Xen Project, which are currently addressing these expectations with various mechanisms and approaches.
4 – 4:25 pm: Zephyr and RISC-V: I Ain’t Afraid Of No Ghosts – Mohammed Billoo
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.
In this talk, Mohammed Billoo will describe the process of getting to Zephyr to run on the UPduino (https://tinyvision.ai/pages/the-upduino), flashed with the neorv32 RISC-V processor (https://github.com/stnolting/neorv32). He will walk through building and flashing the neorv32 RISC-V core on the FPGA, creating a Zephyr application that can output Hello World to the UART, and loading the application to the FPGA. Mohammed will also walk through the necessary Zephyr drivers to get the application running. This talk will demonstrate how combining RISC-V and Zephyr on an FPGA opens up new opportunities for embedded software applications. Using open-source software and firmware on a low-cost FPGA reduces the bar for entry for enthusiasts and hobbyists. The audience will learn the following in this talk:

Relevance of the RISC-V instruction set architecture for hobbyists
Overview and structure of the neorv32 RISC-V processor
Overview and structure of The Zephyr Project RTOS
RISC-V support in Zephyr
Relevant Zephyr drivers
Demo: From Empty Silicon To Zephyr Boot

5-5:25 pm: From an artificial nose weekend hack to a future-proof IoT device – Benjamin Cabe
It was a long weekend in May 2020. Like many of my human siblings stuck at home with time on their hands due to an ongoing pandemic, I was busy trying to perfect my bread recipe. Fast forward to a few hours later, I had assembled an Arduino-based “artificial nose” that used a gas sensor and AI (so-called TinyML) to learn and detect scents (hence potentially the smell of a perfectly fermented sourdough starter). As I open-sourced and started to share the project on social media, it went viral… and I felt like an impostor, as most of the code powering it was, frankly, hackish. Or maybe it wasn’t, as it had the merit of having helped me invent something new, in literally a few hours.
In this talk I will walk you through some of the key features of the artificial nose, and how I eventually rewrote my original code to leverage Zephyr (an open-source real-time operating system) in order to make it easier for myself and the community to extend the project, and run it on a variety of hardware targets.
You will learn, among other things: * How to move from a complex “super loop” to well architected threads and event-based programming ; * How to run TinyML models (ex. TensorFlow Lite) while not compromising the rest of your embedded system ; * How to build an efficient and easy-to-maintain graphical user interface ; * How to leverage Zephyr hardware-abstraction layer.
All the code and demonstrations shown in the talk is open source and available on GitHub, and you are very much encouraged to go ahead and build your own artificial nose after the presentation!

12:30 – 1 pm: Application of the SPDX Safety Profile in the Safety Scope of the Zephyr Project – Nicole Pappler, Stanislav Pankevich
Creating and maintaining a safety critical project comes with a lot of challenges. One central issue is keeping your documentation, starting from planning and guideline documents, down to requirements, safety analysis, reviews and tests, consistent and up to date. These project artefacts often have their own lifecycle and are natively managed in different tools, with usually great traceability capabilities regarding dependencies between these artefacts as long as you stay within one tool or within a (usually propriety) tool family of one single tool vendor. Currently the resulting traceability gaps between these tools are handled either by the popular engineering tools like MS Excel or methods like “search for identical names”, depending highly on manual maintenance. Using SPDX relationships, the upcoming Safety Profile in SPDX 3.1 will provide a model to represent all these dependencies as a knowledge model that can be used both to analyse possible impacts after a change (be it because of a security update or functional variants of your product), provide evidence of completeness and compliance as a Safety SBOM or simply keep track of your product variants. In this talk we will provide both an introduction to the SPDX Safety Profile as well as a real life example using StrictDoc and the Zephyr Project’s Functional Safety scope.
