Alternative to Torizon OS for embedded Linux development

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.

We talk IoT podcast - Cyber resilience act open source

The Cyber Resilience Act & Open Source: achieving compliance for composed products

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.

Raspberry Pi: secure boot enablement

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.

from azure iot hub to kubernetes architecture for Kamea IoT device management platform

From Azure IoT Hub to Kubernetes architecture for IoT device management

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.

Feedback on dm-verity integration under secure boot with Yocto

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.

Yocto or not? Selecting the right build system for your Linux system

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.
