    Hi Alex,

    From where you get this Qt5 Example "qt5-cinematic-experience"? Do you use DM816x EZSDK? Can you try the default Qt examples that comes with EZSDK?

    Regards,
    Pavel

    set "export QT_DEBUG_PLUGINS=1";
    then the print is :

    QFactoryLoader::QFactoryLoader() checking directory path "/opt/autorun/platforms" ...
    Cannot load library /usr/local/qt5/plugins/platforms/libqeglfs.so: (libXext.so.6: cannot open shared object file: No such file or directory)
