I have two QT applications developed using QT 5.6.3 & QT 5.5.1 which are running on i.MX6 platform.
I want to run the same QT applications on the i.MX8M Plus. i.MX8M Plus yocto build has QT latest version(5.15.2).
I don't want to upgrade my QT applications.
Can I downgrade the QT version in i.MX8 M Plus yocto build? What changes are required to perform this activity?
The recipes-qt5 is under sources/meta-qt5. If you have the recipes of your old version QT5, you may try to replace the recipes-qt5 there. But I think this is very hard to modify and you may need to spend a lot of time to fix the errors of compiling. Do you mean your old QT application cannot run on the new version of QT? I think you may modify your code to make your application can run on the new version of QT is more easier.
