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.
Manufacturers keep their proprietary software in private git repositories. During the build, Yocto recipes fetch the private sources from inside a container. This requires a special SSH setup.
Consequences of Choosing the Wrong HMI Terminal
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.
Electronica 2022 Round-Up
The Board-Support Package Is Not Enough!
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
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
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
Kas makes Yocto builds simple. Based on a YAML configuration file, kas starts a container, clones the layer repositories, initialises the conf files and starts building. Each Yocto version builds only on specific host Linux versions. The kas container frees Yocto builds from this restriction.
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
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,
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
