Screen rotation - Beaglebone QT5/Eglfs

[m.esmaeelpour]

Hi folks!

I did so much search (Google/Qt forums/beaglebone related IRC/Forums/groups) to find any solution to run my QT/QML apps in portrait mode in my :
beaglebone black(debian stretch)
QT 5.7.1 (install by apt-get)
eglfs

but i couldn't achieve that.
i used QT_QPA_EGLFS_ROTATION=90, but not worked for me.

*** I want a solution apply to QML/QT/Opengl based Apps, I mean all Qt related apps, no any specific types of apps

Any idea/solution/help/point/... ?

Thank you guys
