Create your own Embedded Linux in Yocto and launch Qt based GUI
This video is a technology demonstration of using embedded browser (qtwebengine) running on Raspberry Pi 4. The idea was to develop a scalable user interface which will allow the user to play media from web, chat and access social and business features. You can download linux image for your Pi 4 it from the link in my blog. Please make sure to watch my previous videos if you want to build such embedded linux image yourself.
In simple words, this video shows a custom embedded linux OS created in Yocto which starts a Qt based GUI application.
