Technical blog articles written by our embedded software experts on embedded Linux, automated testing, cybersecurity, IoT and more.
This article provides an in depth and technical look at Torizon OS provided by Toradex: its architecture, strengths, and the limitations commonly reported by engineering teams. It then introduces Welma, a Yocto based, hardware agnostic alternative that delivers strong ownership, independence, and quality assurance for device manufacturers seeking a production ready Linux platform.
This article is based on a conference given by our technical team at Embedded World.
We dive deep into a topic that every embedded Linux team eventually grapples with: how to upgrade your Linux kernel in Yocto, what constraints shape your roadmap, and how vendor support (or the lack of it) impacts your long-term strategy.
As the European Union prepares to enforce the Cyber Resilience Act (CRA), one topic dominates technical discussions: how the Cyber Resilience Act impacts open-source software. For manufacturers relying on open-source components such as Linux, Yocto, or community-maintained libraries, the regulation introduces new obligations around security, documentation, and vulnerability management.
This article is based on insights shared by Pierre Gal (The Embedded Kit) and Michael Röder (Avnet Silica) in the latest feature of We Talk IoT.
Establishing a verified boot chain on Raspberry Pi 4 is a fundamental requirement for securing the platform against unauthorized code execution and tampering. In this article, Simon, software engineer at The Embedded Kit, details the full procedure for enabling secure boot on Raspberry Pi systems, including hardware prerequisites, build time configuration steps, cryptographic signing operations, and the verification stages involved in establishing a trusted boot sequence.
Our customer came to us with a challenge that many railway manufacturers face today: keeping a 20 year lifecycle product secure in a world where vulnerabilities appear daily and regulations evolve faster than hardware cycles.
Here’s how we helped them turn a growing maintenance risk into a predictable, scalable process.
A few years ago, we developed an IoT device management platform called Kamea. The goal was simple: to create a solid foundation of reusable components to accelerate connectivity projects and deliver value faster. Today, we’ll share our experience migrating Kamea from a managed PaaS solution on Azure IoT Hub to a self-managed infrastructure based on Kubernetes.
During the Yocto Virtual Summit, we had the opportunity to share our experience on Secure Boot and, more specifically, on the integration of dm-verity within a Yocto-based Linux distribution. This article summarizes what we implemented, the challenges we faced, and the lessons learned.
Let’s jump a few years back: The rise of SaaS in device management SaaS (Software-as-a-Service)…
This article is based on a talk given by Chris Earls, embedded software expert at Witekio, during Embedded World North America. It explores the decision-making process behind choosing a build system for embedded Linux devices, with a particular focus on the Yocto build system.
