Qt BareMetal on Cortex M4

[iRoamSubtrees]

Hello there,
I just started with Qt and embedded systems recently. I am currently working on a school project (undergrad) where I have to look for possibilities to run the Qt Framework Bare metal on a Cortex M4. Honestly I've lost myself in the QPA (QPlatformScreen, QPlatformIntegration, etc.).
I'm trying to understand how exactly the Framework/QPA is interacting with the OS and/or drivers.

Does anyone have an idea where I should look next?
Any Ideas are welcome :)

Thank you

Hi @iRoamSubtrees

Running on an M4 is a pretty tough target, but should be doable.

I think the best place for questions would be the development mailing list:
http://lists.qt-project.org/mailman/listinfo/development

Or on IRC, channels #qt or #qt-labs
http://wiki.qt.io/Online_Communities

Thanks for the suggestions. Saddly didn't got lucky there.
Does anyone has any experiance with running Qt on CMSIS or BareMetal?

AFAIK, it is impossible.

That's what I've heard too. At the moment I'm looking for why that is. Already knees deep in the Source^^
But no luck yet.

Essentially you are looking at porting Qt to new platform.

I'm completely out of my depth here. In general having POSIX makes your life easy, but apparently it isn't a must if you have time and skills.
