I never got the hang of UML: overly complicated, hard to understand, too close to code. Hence, I was skeptical about C4 diagrams when I… Read More »Visualising the Architecture of Qt Embedded Systems: Context and Container Diagrams
Kas makes the setup of a Yocto build environment super simple and super fast. We call kas with a project configuration file: kas-container build ./eu-terminal-distro.yml. Kas starts a Docker container, clones the layer repositories, initialises the Yocto configuration files (local.conf and bblayers.conf), and starts building the embedded Linux system. Most Linux BSP providers don’t make a kas configuration file available. I’ll show how to convert a repo manifest file into a kas configuration file in this post.
With Team Topologies, Matthew Skelton and Manuel Pais have written a brilliant book how to create a high-performance software development organisation with the best team structure and interaction. Organisations are complex adaptive systems that change as the result of the interactions between their components (e.g., the teams) and the interactions with other systems (e.g., the rest of the organisation, competitors, suppliers, technology and market trends). The resulting changes are hard to predict and hard to control.

The Qt version of an embedded Linux system is tied to the Yocto version. Yocto 2.7 (Warrior) comes with Qt 5.12, Yocto 3.1 (Dunfell) with Qt 5.14, Yocto 3.2, 3.3 and 3.4 with Qt 5.15 . There is no Yocto version with Qt 6 yet. How can we build Qt 6.2 against the SDK of old Yocto versions?
Read More »Building Qt 6.2 For Old Yocto VersionsI gave a talk at Meeting Embedded 2021 on 4 November 2021. First, I introduced the hexagonal architecture (a.k.a. ports-and-adapters architecture) in general. Then, I showed a walking skeleton of the architecture for a harvester terminal.

Creating an architecture means answering many questions about the ecosystem, in which the Qt embedded system operates. While the questions are very similar for all Qt embedded systems, the answers and their priorities differ. So, you should be able to transfer the questions and answers from my running example, a harvester terminal, to your system.
