Beaglebone Black EGL Screen rotation

I cannot get over with display going in portrait mode when rendering EGL full screen.

I want to make the change permanent portrait mode.

echo 1 > /sys/class/graphics/fbcon/rotate_all

does rotate the fb as text and linux fb mode, but when using the QT on eglfs or EGL app;s like gles1test1 is allways landscape.

Though the


does nothing.

Any help would be appreciated.

Just said in the post, if you read it all, it just rotates the fb not the EGL context.
