Fast boot OS for QT Application

onurkse

Hi guys, I just want to run QT application on Raspberry Pi screen. In my current design, I am running my QT application on Raspberry Pi OS. But it takes too long to wait for the OS to boot. How can I make the raspberry pi boot in a very short time like 2-3 seconds and have my QT application appear on the screen? Is there a Raspberry Pi OS modified to run QT only?

Hi and welcome to devnet,

You should then look into something like Boot2Qt (commercial product of the Qt Company) or the yocto project.

Unfortunately, I cannot buy a commercial product. I am looking for a solution that I can handle for free. I will try yocto project.

Even not using yocto but buildroot the concepts of what is required to make rpi boot faster are there. Also using Qt application.
