Qt5.11 with eglfs Freeze after few hours



  • I'm under evaluting Raspberry Pi Zero + Yocto Thud + Qt5.11 + eglfs. I got problem that the screen has freeze after few hour running Qt Demo Application Qt5_CinematicExperience, but I still can able to remote ssh to the device. I tried to kill Qt5_CinematicExperience with killall Qt5_CinematicExperience and kill <PID>, but the app still there when I check from TOP command.

    I can't see debugging message because i can't close the Qt5_CinematicExperience.

    CPU usage for this application around 80-98%.

    Anyone to know the clue of the root cause of this problem?

    Hi,

    Did you check if there's a kernel panic/warning in your logs ?
