In my experience, you should use the latest version of QT creator and expect it to work with whatever version of QT you are developing for.

We have to develop a QT application for our AM57x Development board. which version of QT creator is supported with AM57x ?
Is there any example programs and getting started tutorials for the same.

I am sorry for the confusion.
