December 2020 saw the launch of Qt 6 – the first new major version since 2012. I wanted to find out how fit Qt 6.0 is for Qt embedded systems. I took the driver terminal of the ROPA sugar beet harvesters and migrated it from Qt 5.12 to Qt 6.0 as a side project. The...

Architecture of Qt Embedded Systems: Getting Started
Which system-on-chip is best suited for your Qt embedded system? Should you build a custom Linux system with Yocto, use a container OS or a desktop Linux? Should you use Qt Commercial or Qt LGPLv3? How will the system be updated? What are the operating conditions of the system? How does the system communicate with...

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 these steps in a breeze, because we spent quite some time to define a QtCreator...

Webinar: Building Embedded Applications from QtCreator with Docker
In a webinar organised by The Qt Company on 8 July 2020, I showed how QtCreator builds an embedded application against a Qt SDK encapsulated in a Docker container. QtCreator doesn’t know which Yocto version was used for building the Qt SDK and which environment variables must be set for the SDK. QtCreator forwards the...
Qt Embedded Systems – Part 2: Building a Qt SDK with Yocto
We want to develop the Internet radio application for the Raspberry Pi in the same way as for a PC. We change the source code in QtCreator and run the application. QtCreator cross-builds the application on the PC for the Raspberry Pi, deploys it with SSH to the Pi and runs it on the Pi....
Qt Embedded Systems – Part 1: Building a Linux Image with Yocto
In Part 1 of the series on Qt Embedded Systems, we build a custom Linux image with Yocto for the Raspberry Pi 3B. When we power on the embedded device, it starts an Internet radio application – called Cuteradio. This QML application is very simple: it can only play a single, hard-wired station. Despite its...
