What if we could prevent other recipes from being rebuilt each time? The Yocto community has been wanting a solution for this for years, and now it’s here! Enter bblock. With bblock, you can lock recipes - and even a single task inside a recipe - to prevent them from being rebuilt. Knowing how to use bblock will help you save a lot of development time in all your Yocto based projects! ypdd-oss-elce-2024-52235-bblock-rocks-lock-your-yocto-recipes-and-save-your-time Julien Stephan en This presentation will introduce bblock, cover its key use cases and provide a practical guide on how to use it. false Slides https://pretalx.com/ypdd-oss-elce-2024/talk/WKUY8J/ https://pretalx.com/ypdd-oss-elce-2024/talk/WKUY8J/feedback/ Styhead Talk 2024-09-19T11:00:00+02:00 11:00 00:40 In this presentation, we will explore practical security measures for embedded systems using Trusted Execution Environment (TEE) and its secure storage implementations. We will cover the benefits of TEEs, the idea of a root of trust, and share insights from our experience of integrating it within our Yocto-based Secure Embedded Linux distribution, Zarhus OS. Attendees will gain practical hints and tools to enhance the security of their embedded systems. ypdd-oss-elce-2024-54417-practical-security-for-embedded-systems-implementing-tee-and-secure-storage Tymoteusz BurakDaniil Klimuk en In this session, we will delve into the essential aspects of securing embedded systems. The session begins with an introduction to the importance of security in embedded systems, followed by a brief presentation of key concepts such as the root of trust and, eventually, the architecture of Trusted Execution Environments (TEEs). We will then discuss the practical implementation of TEEs and its secure storage implementations, detailing how they function and the security benefits they provide. Next, we will move to the current support within Yocto, discussing available tools, resources, and ongoing developments that support secure implementations. This discussion will be illustrated with our custom Yocto-based Secure Embedded Linux distribution, Zarhus OS. We will explain its design, the security features it incorporates, and how it enhances the security of embedded systems. This segment will provide practical insights into the development and deployment of a secure embedded Linux distribution. The session will also include a case study of our involvement in the CROSSCON project, an initiative aimed at standardizing the IoT security stack, and the problems it tackles. By the end of this session, participants will be aware of TEEs and its implementations, equipped with the knowledge and tools on how to implement these security measures in their own embedded systems. They will also gain insights from practical examples and ongoing projects to aid in their security implementations with Yocto. false Slides https://pretalx.com/ypdd-oss-elce-2024/talk/9VBPNF/ https://pretalx.com/ypdd-oss-elce-2024/talk/9VBPNF/feedback/ Styhead Talk 2024-09-19T11:45:00+02:00 11:45 00:40 Let's distill the usefulness of our Yocto and Docker session for fellow embedded developers into a succinct description: 1. Efficiency and Consistency: - By adopting Docker for Yocto builds, developers ensure consistent environments across teams. - No more time wasted troubleshooting host-specific issues—Docker provides a stable foundation. 2. Collaboration Made Easy: - Docker images can be shared effortlessly. Colleagues can jump into the same build environment without setup hassles. - Collaborative development becomes smoother and more productive. 3. Reproducible Builds: - Docker containers encapsulate dependencies, ensuring that builds are reproducible. - Say goodbye to "it works on my machine" scenarios. 4. Avoiding Host System Pitfalls: - Docker isolates Yocto builds from host system changes. - Developers can focus on the project, not system quirks. 5. Live Demo: Real-World Application: - Our BeaglePlay demo showcases practical usage of Yocto and Docker. - Attendees will witness the power of this approach firsthand. ypdd-oss-elce-2024-51635-yocto-and-docker-containers-streamlining-build-processes-for-embedded-systems Chirag Shilwant en In this session, we'll cover the following key points: 1. Introduction to Yocto Project and Docker: - We'll start by understanding the fundamentals of the Yocto Project. This open-source collaboration initiative empowers developers to create custom Linux-based systems for embedded devices. - Next, we'll explore Docker, a powerful containerization platform. Docker allows us to package applications and their dependencies into lightweight, portable containers. 2. Drawbacks of Running Yocto Builds on the Host: - Traditionally, Yocto builds were executed directly on the host system. - However, this approach has drawbacks: - Dependency Hell: Managing dependencies and ensuring consistency across different development environments can be challenging. - Host System Variability: The host system's configuration (Linux distribution, libraries, etc.) affects the build process. - Reproducibility Issues: Documenting build steps doesn't guarantee consistent results across different machines. 3. How Docker Addresses These Challenges: - Docker containers provide an isolated environment for Yocto builds: - Consistency: Everyone uses the same container, ensuring reproducibility. - Portability: Developers can share Docker images, making it easier to collaborate. - Avoiding Host System Interference: Docker shields the build process from host system changes. 4. Live Demo: Building BeaglePlay Image via Yocto with ti-docker-images: - We'll demonstrate how to build BeaglePlay (an embedded system) using the ti-docker-images repository available on GitHub. - These Docker images are specifically tailored for Yocto builds, ensuring a consistent and reliable environment. - By following our live demo, you'll see firsthand how Docker simplifies the Yocto build process.
