Our application uses v4l2src gstreamer plugin to capture video from CSI-2 ports. When opening/closing the application’s video pipeline, there’s a chance that the whole system freezes. Logs from serial port shows “Unable to handle kernel paging request” or “Watchdog detected hard LOCKUP on cpu” etc.
Is there anyone else having the same experience? What to do to debug? Thanks in advance.
PS. my TX2 uses R28.1’s kernel
