Unsolved Rpi4 Qt5 Qml drmModeGetResources failed error

[hbabuc]

Hello everyone,

I have been created a build with Buildroot. Also did it everthing on this comment -> https://www.raspberrypi.org/forums/viewtopic.php?t=263418#p1614833
My config is:
Rpi4-64
QT5-Qml
Mesa v3d-vc4 opengl es 2.0

When I try to run my qt qml application on this build, I'm getting this error:
QStandardPaths: wrong permission on runtime directory /usr/bin/, 7755 instead of 7700
drmModeGetResources failed (Operation not supported)
no screens available, assuming 24 -bit color
Cannot create window: no screens available.

Summary : I need to run my qt5 qml application on Rpi 4 with hw accelerated.
