Embedded Programming for Raspberry Pi with Quick Download

I am a student and I have problems with my new project:

  • A small screen displaying information about the car, etc. Simple version of a computer.

It has been a month with my raspberry pi, and I can’t find a solution to my main problem: A simple Linux distribution with really fast boot and the ability to develop GUI applications

My main evolutions in my project were:

  • I tried Arch Linux for a while. But 20 seconds of boot is not fast enough. And I can not work normally with the GUI
  • I tried RPi-Buildroot from Gamaral. This is a really good buildroot version designed for raspberries pi. 3 seconds of download is really amazing to see. But I was unable to get anything other than "Hello, World" using its Cross Compiling. ( RPi-BuildRoot Link on Github )

I just need to be guided by what I need to do to make this work. If I get a simple user interface starting in less than 10 seconds, I can review my project.

I think RPi-BuildRoot is a Great tool that I can't find ...

Thanks! And sorry for the bad English;)

I am using a pre-configured IPE R2 root root environment.

Many thanks to this. It uses only the read-only root file system, and it took about 4 seconds to load into my application. The native application uses OpenGL for the GUI.

rpi-buildroot gives you a really basic default configuration. It already gives you the OpenGL library, but you need to configure it to add anything else.

So, after assembling for the first time, do

make xconfig

and go through it to find the graphic libraries you want to use. For example, you can enable qt5 and qt5declarative in the Graphic Libraries and Applications menu, and then get QML. See buildroot documentation and QML documentation
