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

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

  • Continues RTPS DDS (ROS Middleware) messages popup while running CPU varient as shown below. This is a known behaviour with RTPS middleware as mentioned here.

  • Unsynchronized messages popup randomly on Streamlined app

    [rectify_resize_fpga_streamlined_node-1] [WARN] [1662749510.825170570] [ResizeNodeFPGAStreamlined]: [image_transport] Topics '/camera/image_raw' and '/camera_info' do not appear to be synchronized. In the last 10s:
    [rectify_resize_fpga_streamlined_node-1]        Image messages received:      29

  • Sometimes the application exits with the following xclExecBuf error

    [rectify_resize_fpga_streamlined_node-1] [XRT] ERROR: unable to issue xclExecBuf

    Reloading the firmware with xmutil fixes this issues as shown below

    ubuntu@kria:~/ sudo xmutil unloadapp
    ubuntu@kria:~/ sudo xmutil loadapp kr260-perception 
    ubuntu@kria:~/ ros2 launch perception_2nodes
