Open Source Summit Japan (Tokyo)

December 5, 2023 - December 6, 2023

Open Source Summit Japan, happening on December 5-6 in Tokyo, 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. 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. At Open Source Summit Japan, those events include: Critical Software Summit, Embedded IoT Summit, LinuxCon, Open Source Leadership Summit and more.

Register here for in-person attendance.  Virtual registration is not required to access the event live stream. All conference sessions will be live-streamed to the Linux Foundation YouTube channel with freely available access during the event. Live stream links for each session can be accessed from each session listing in the schedule (coming soon). Want more information on virtual attendance? Click here for more information.

Zephyr will be featured at the OSSummit in several sessions including (all session times listed below are in Japan Standard Time):

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.

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.
