Known Issues

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.

  [component_container-1] 2022-10-13 16:30:56.972 [RTPS_MSG_IN Error] (ID:281473539668192) Problem reserving CacheChange in reader: 01.0f.da.c1.9f.f4.74.8f.01.00.00.00|0.0.2f.4 -> Function processDataMsg
  

• 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
  [rectify_resize_fpga_streamlined_node-1]        CameraInfo messages received: 24
  [rectify_resize_fpga_streamlined_node-1]        Synchronized pairs:           9
  

• Sometimes the application exits with the following xclExecBuf error

  [rectify_resize_fpga_streamlined_node-1] [XRT] ERROR: unable to issue xclExecBuf
  [rectify_resize_fpga_streamlined_node-1] [XRT] ERROR: failed to load xclbin: Operation not permitted

  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 trace_rectify_resize_fpga_streamlined.launch.py
