Compatibility between Yocto and Qt 6 Versions
We can build the Qt versions from 6.2 to 6.5 with the meta-qt6 layer for the Yocto versions 3.1 to 4.1. This is a big time saver. Yocto \ Qt6.56.46.36.24.2 (Mickledore)TT--4.
Embedded Linux
Every SoM comes with a makeshift Linux system. Every manufacturer must add OTA updates, security measures, remote access, GUI frameworks and more. That's a lot of duplicated work. This would be much more efficient, if a SoM maker provides a Linux with all the features ready for use by manufacturers. Toradex does this with Torizon. We show how manufacturers can benefit from this groundwork with minimal effort. Torizon even runs on non-Toradex SoMs. SoM = Solutions on Module.

Creating A Custom Yocto Layer
After having built the reference Linux image from a SoM, SoC or terminal maker and having run it on the board, we must inevitably custom-tailor this image to our needs. We must create our own Yocto layer. We must remove
Installing Linux Images on Toradex Verdin Boards
In the post Setting Up Yocto Projects with kas, we built the Linux image for the Toradex Verdin iMX8M Plus. It's time to flash the image on the board using the Toradex Easy Installer (TEZI). It's
Visualising the Architecture of Qt Embedded Systems: Context and Container Diagrams
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 first heard about them. When I saw Simon Brown using them in his talk Modular
Setting Up Yocto Projects with kas
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
My Talk "A Successful Architecture for Qt Embedded Systems" at Qt Day Italy 2021
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
Architecture of Qt Embedded Systems: Operating Conditions
Operator conditions like light, temperature, water, dust and vibration are a rich source for constraints and qualities of a system architecture. They affect the SoC, display and connector selection, the touch gesture recognition, the communication between system components, the cabling,
How to Set Up QtCreator for Cross-Compilation with CMake in 5 Minutes
Setting up QtCreator for cross-compilation with CMake took me 15-20 hours the first two or three times. The next half a dozen times took me 4 hours on average. The last two times took me 5 minutes - using the
Showing Wayland Compositor Fullscreen in Portrait Orientation
Our Qt embedded system is displayed on a monitor mounted in portrait orientation. The system runs the Wayland compositor Weston as a window manager. HMI applications are shown rotated by 90 degrees - in landscape orientation. The system toolbar of
Cross-Compiling Qt Embedded Applications with QtCreator and CMake
We change the code of our Qt application in QtCreator and press the Run button to try the changes on an embedded device. QtCreator cross-compiles the application, deploys it to the device and runs it on the device. QtCreator performs
