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...

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...
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...
Yocto Builds with CROPS Containers
In a recent post Using Docker Containers for Yocto Builds, I suffered an episode of NIHS (not-invented-here syndrome). I wrote a Dockerfile for Yocto builds. Stefan Agner pointed out in his comment that the CROPS project provides ready-made containers for Linux distributions like Ubuntu, Fedora and others. The crops/poky-container enables us to start our...
Using Docker Containers for Yocto Builds
We want to build a custom Linux image with Yocto for the Raspberry Pi 3 model B (BCM2837). The Linux image contains a very simple Internet radio application using Qt 5.11 and the eglfs graphics backend. Our colleagues shall be able to repeat the build easily – now, in three years and even in...
