Bluetooth Mesh and Zephyr - Martin Woolley, Bluetooth SIG
Bluetooth mesh was released in 2017 and allows secure networks of thousands of Bluetooth devices to be created. It uses Bluetooth Low Energy (LE) for radio communications and inherits its optimised, low power and other characteristics.

The Zephyr open source OS supports Bluetooth mesh on devices as affordable as the BBC micro:bit.

This session will explain the fundamental technical concepts of Bluetooth mesh, including models, messages, publish/subscribe, node composition and security keys and will explore what’s involved in implementing firmware that uses Bluetooth mesh on the Zephyr RTOS platform.

Multi-core Application Development with Zephyr RTOS - Alexey Brodkin, Synopsys
Performance in Desktop, Server, HPC and even smartphone applications has been scaling rapidly in recent years via multi-core, continuously increasing the number of cores on a processor chip. The same principle has been extending to embedded systems, where multi-core designs are increasingly more pervasive in applications such as 5G data processor, edge IoT, Machine Learning and many more.

This presentation will examine multi-core application options and considerations using the Zephyr. We'll start from exploration of use-cases where multiple CPU cores might be beneficial for deeply embedded system including both asymmetric & symmetric multiprocessing (AMP & SMP). Then we'll discuss current state of multi-core support in Zephyr: what is already implemented and what's still missing. And in the end we will highlight challenges associated with designing high performance software applications for multi-core hardware using samples on boards currently supported in upstream Zephyr project.

IoT Solutions for Life-safety Applications - Viktor Semenov, TowerIQ
The difference from the previous version: the previous presentation was given on the non-technical event and I had to use very basic language explaining technical details and new features we're working on. This time I'd like to explain what principals were used to achieving the desired level of robustness in a very inert industry of fire alarms and radio communication systems.

Abstract: Victor will explain what principles allow to build a robust and reliable wireless service to provide life-safety grade communication system to fulfill the special requirements of first responders during the possible accident.
This presentation will show how to accomplish high durability using the open-source software and hardware components and right way of composition and reinforcement.

The 'S' in IoT stands for Security - Viktor Petersson, WoTT & Andrew Martin, Control Plane
IoT security isn't rocket surgery, but a race to market has left a proliferation of insecure, unpatchable devices strewn across the internet. Well-established software delivery and security best practices are routinely ignored, and a series of laughable breaches has left users and governments scrabbling for better solutions.

Recent advances in IoT-friendly hardware have expanded the options available to manufacturers, and paved the road to lightweight containerisation of connected devices. This talk will discuss the current state of the art in consumer and industrial IoT device security, examine some recent vulnerabilities, breaches, and attacks, and explore how to use containers to secure devices from current and future threats.

BoF: Multibuild for Zephyr RTOS - Marti Bolivar, Nordic Semiconductor
The Zephyr RTOS build system currently supports generating a single application image. This build is isolated from other related images, such as bootloaders, secure vs. nonsecure Arm TrustZone images, multi-core applications communicating via IPC mechanisms, etc.

This is a problem because these images can be interdependent in ways that require compatible configurations between images (including Kconfig, device tree chosen nodes, linker script memory layout, etc.). Since the build system is agnostic to other images, this is left to the application developer or system designer to manage. That's unnecessarily error prone, since the build system could check for common errors itself if only it knew about all the executables in the system.

Different Zephyr downstream distributions have solved this problem in different ways, but there's so far no consensus on how to solve this problem upstream. This BoF is meant to keep the conversation going among anyone who is interested in this topic.

Zephyr OS Memory Protection - Andrew Boie, Intel Corporation
In this presentation we describe the MPU-based memory protection features we have introduced in the Zephyr RTOS, showing novel techniques for working around the limitations of MPU hardware, implementing security domains in a physical memory map (no virtual memory), and maintaining API compatibility with platforms that do not have an MPU. We will show the permission management system to control access to kernel objects and device driver instances, and how both static and dynamically allocated kernel objects are managed. There will be some discussion on how global objects are routed to application memory domains and how we automatically manage size/alignment constraints of common MPU hardware. We will show how simple it is to define system calls. We have implemented futex-like capabilities to implement IPC mechanisms with no system calls required for uncontended locks. We will conclude with ongoing areas of development.

A Dive into Zephyr Device Driver Model - Tomasz Bursztyka, Intel Corporation
Besides the kernel, the second most important part of an OS is how all peripherals are exposed to the user, finally enabling the OS to access the world outside of the CPU it is running on.

Zephyr solves this by proposing a very simple yet flexible device driver model,
deeply integrated with the device tree (DTS), making porting hardware to it efficient and easy.

Through real use cases and from a developer perspective, this model will be explained as well as the life cycle of a device driver, whether it is native or ported from an existing HAL.

Writing Your Own Gadget with Zephyr OS - Andrei Emeltchenko, Intel
In this talk the author describes possible ways of connecting IOT devices using embedded boards running Zephyr OS, connected to host PC via USB. In particular, the following sample cases are explained: Export custom radios from Zephyr to Linux host (IEEE 802.15.4 and Bluetooth) so that Zephyr board behaves as a radio adapter for Linux. Author outlines the possibility of making IP bridge out the Zephyr-based SOC board. The device in this scenario behaves like USB Ethernet controller using ECM or RNDIS protocols. Part of the presentation is dedicated to OS drivers for the Zephyr-based boards. Author describes custom Linux driver for IEEE802.15.4 over USB; using standard OS drivers for well-defined USB classes like Bluetooth and using OS Descriptors for Windows OS to locate correct drivers (RNDIS). In the end the brief explanation of some new USB features (webusb) and possibility of using them for easy board access with a browser.

Building a Debug Probe with the Zephyr RTOS - Johann Fischer, PHYTEC Messtechnik GmbH, Germany
Many of the Arm Cortex-M based development boards supported by the Zephyr RTOS have an on-board chip that acts as a debug probe. This is typically based on the ARM Mbed DAPLink open source project. This provides the developer with several interfaces: USB MSD for drag-and-drop programming, USB CDC-ACM for console output and a CMSIS-DAP based debug channel over USB HID. The DAPLink project uses the Keil RTX OS and requires the Keil MDK-ARM or ARM Compiler 5, which makes it impossible to build it on Linux based systems.

​The talk is about whether it would be possible (and how) to build a debug probe on top of the Zephyr RTOS. Zephyr already has a reasonably stable USB device stack with CDC-ACM and MSD support. The author will give a overview about the structure of a debug probe, Host Interface Cirtuit, Serial Wire and SWD protocol. Furthermore, the author will introduce the implementation of the CMSIS-DAP in Zephyr RTOS.

Integrate ROS into EdgeX - Startover of Edge Computing System - Tiejun Chen, VMware
ROS - The Robot Operating System is a flexible framework for writing robot software at the very beginning. It is a set of tools, libraries, and conventions of creating complex and robust robot behavior across a wide variety of robotic platforms. Essentially it is a middleware over Linux distribution but more importantly, it is broadly adopted across many industrial automated platforms and even automotive systems. The surging popularity of edge computing and or fog computing, really needs to play into various edge software framework. This year Linux Foundation launched LF edge including a variety of edge sub-projects like EdgeX Foundry. So in our presentation we'd like to review and discuss if we can integrate ROS into EdgeX to build a unified edge system solution like 1: Architecture; 2: Support EdgeX with ROS device nodes; 3. Enable a basic machine learning framework with ROS library like opencv; 4: Over light weight preempt-rt Linux vessel; 5. vision of edge computing cluster.

Running Linux on Constrained IOT Device - Rui Silva, Linaro & Tushar Khandelwal, Arm Ltd.
It is often assumed that tiny IoT systems are too limited to run Linux, and a small operating system like Zephyr is a better choice. However, using a small OS means tradeoffs on functionality, and sometimes Linux would be a better fit. Some devices have enough resources that Linux is feasible if we can get the footprint down. This presentation will talk about the work we have been doing to do memory optimizations in Linux kernel and file systems and uses it to build an IoT device frameworks that run on a small platform with limited ram and XIP flash.
