Hi, Murali, As I wrote in my instructions, there is only one way to run a Qt Quick 2 application directly on BeagleBone Black. Namely as a single fullscreen application using the EGLFS platform. So make sure the graphical environment is not started (no X or Wayland), and run this in a console: $ export QT_QPA_PLATFORM=eglfs $ export QT_QPA_EVDEV_KEYBOARD_PARAMETERS="grab=1" $ export QT_QPA_EVDEV_MOUSE_PARAMETERS="grab=1" $ /path/to/the/dashboard/example
If this doesn't work, your OpenGL ES drivers are probably not installed correctly and you should try following my instructions to install them.
