Known Issues

This document records known issues or gives behavior that might be unexpected some explanations.

First review the FAQ for commonly encountered issues across the Kria SOM applications.

  • Some monitors will display in non-desktop mode (running docker on serial port or SSH session) but not in Ubuntu® GUI mode.

  • Make sure that AR1335 sensor module is the only video device connected to board. The application might fail if other media devices are connected to board.

  • During the application launch, the following warning is seen. This is a bug from trying to use Gstreamer with OpenCV. You can ignore this warning as it will not affect the functionality.

    [ WARN:0] global /usr/src/debug/opencv/4.4.0-r0/git/modules/videoio/src/cap_gstreamer.cpp (935) open OpenCV | GStreamer warning: Cannot query video position: status=0, value=-1, duration=-1
  • While terminating the application with ctrl + C, you might see the following error messages which can be safely ignored:

    ^C!!! Failed to read frame from mipi media node. Please make sure the design is loaded
