How Bosch contributes to Open Source
After the welcome, Lavanya Ravi, an Associate Software Engineer at Bosch, took the floor. As a software engineer representing the Security Building Blocks team at Bosch, Lavanya expressed her excitement about the meeting and emphasized the invaluable opportunity for networking and collaboration within the dynamic open source community. She highlighted Bosch’s 25-year history as a software leader, highlighting their extensive range of software products and services. She proudly shared her team’s contributions to numerous open source projects, setting the stage for Yashwanth, a teammate and Firmware Security Engineer, to delve deeper into their open source efforts. He shared insights into their team’s focus on innovation with 75% of their projects being open source. He discussed significant contributions to the Rust programming language and shared their journey from a small team with a vision to implement Rust in the Bosch ecosystem to now having over 500 people aligned with that vision. Singh highlighted two major projects, Rust Boot and Shakti, underscoring their commitment to secure bootloader development and support for open source processor design, respectively. Yashwanth also introduced the Shakti Rust SDK, which enables secure booting for Shakti processors, and discussed plans for integrating Rust into Zephyr.

Embarking on Embedded Adventures: A Beginner’s Guide to Zephyr and Open Source
During the meetup, Akarshan Kapoor, a third-year undergraduate student in the Department of Data Science at IIT Mandi, shared his journey into open source and Zephyr. He discussed his introduction to open source through events like Hacktoberfest and participation in programs like Google Summer of Code. Akarshan’s talk focused on his Google Summer of Code project, which involved developing a driverless scanning system and metadata extraction tool. During an open source conference, he discussed his discovery of Zephyr and its role as a small-footprint kernel for embedded systems. He offered insights into getting started with Zephyr, emphasizing the importance of understanding system design basics and exploring the documentation.
Greybus for IoT using Zephyr RTOS and Linux
Following Akarshan’s engaging presentation, Vaishnav M A, a software engineer at Texas Instruments, discussed the use of Greybus for IoT applications using Zephyr RTOS and Linux. Greybus is an application layer protocol that was originally developed for Google’s Project Ara modular smartphone project. Greybus has simplified the integration of remote sensors and actuators by utilizing BeagleConnect technology from BeagleBoard.org. This enables plug-and-play functionality with minimal low-level firmware development. The presentation showcased the potential of Greybus for IoT applications, leveraging Zephyr RTOS and Linux for seamless connectivity and customization in embedded systems.
Bringing SEU Resilience to Zephyr: A Journey of Integration
During his presentation titled ‘Bringing SEU Resilience to Zephyr: A Journey of Integration,’ Navinkumar, a Senior Engineer at Intel Corporation, shared insights on integrating Single Event Upset (SEU) drivers into the Zephyr Community. He explained that SEUs occur due to cosmic rays or external events, causing temporary hardware errors without permanent damage. Navinkumar demonstrated the effects of Single Event Upsets (SEUs) using examples such as election discrepancies and energy meter inaccuracies. He emphasized the significance of SEU drivers in Zephyr, especially for Field-Programmable Gate Arrays (FPGAs), where continuous monitoring is crucial due to the placement of hardware logics in configuration RAM. Navinkumar introduced the implementation of SEU drivers in Zephyr, showcasing APIs for error detection, injection, and simulation. He outlined the Zephyr development process for integrating new APIs. He emphasized the importance of RFC creation, review, and eventual code merging.
After a short break sponsored by Google, the event continued with presentations from industry experts. These included Manojkumar Subramanian from Electrolance Solutions, Nagamahesh Gamidi from Timesys Corporation, Dhruva Gole from Texas Instruments, and Subrata Banik from Google. Each presentation offered a unique perspective on Zephyr’s architecture, ecosystem, and security landscape, providing attendees with a comprehensive understanding of the RTOS and its applications.
Exploring Zephyr: A Modern Embedded RTOS framework.
During his talk, Manojkumar, an embedded systems enthusiast from Malaysia, shared his experience with Zephyr RTOS and its impact on his personal and professional life. He initially had doubts about Zephyr, but eventually adopted it due to its user-friendly interface and comprehensive features. Manojkumar emphasized Zephyr’s flexible architecture, extensive documentation, developer-friendly tools, and robust ecosystem. Manojkumar emphasized the importance of Zephyr’s shell utility, logging capabilities, tracing functionality, device tree support, and integration testing framework. He demonstrated how Zephyr has revolutionized embedded software development, making it more accessible, efficient, and scalable through real-world examples.
Navigating the Open Source Security Landscape: Effective Strategies for Zephyr Devices using SBOMs, CVEs, Vigiles
In this session, Nagamahesh Gamidi, Business Development Manager and Solution Architect at Timesys Corporation, presented “Navigating the Open Source Security Landscape: The talk focused on effective strategies for Zephyr devices using SBOMs, CVEs, and Vigiles. The presentation addressed the persistent challenge of staying ahead of security threats in the rapidly evolving world of IoT and embedded systems. The presentation discussed managing security in embedded systems. It emphasized the importance of understanding CVEs, identifying blind spots, and prioritizing risks. Vigiles, a SaaS tool, aims to streamline securing Zephyr-based devices. The talk provided participants with the knowledge and tools to adopt a more comprehensive approach to security by offering insights on how to effectively read and prioritize CVEs and identify real threats.
