D435 realsense cannot work at Kaya

Dear,

D435 realsense does not show any video at kaya.

  • JP4.2.1 image is running on the developer kit.
  • realsense FW: [b]5.11.11.100/b and 5.10.06 (5.10.03 is not listed at download site)

Issue 1: D435 is connected at USB 2.1
realsense_viewer which is included in librealsense shows both depth and RGB video well.
But it starts with this message:
25/09 12:48:09,378 WARNING [547757199808] (ds5-timestamp.cpp:64) UVC metadata payloads not available. Please refer to the installation chapter for details.

Issue 2: Kaya examples[object detection, follow me etc] that use RealSense do not show anything on the screen

Any idea about it please?

Thanks,

Cleared!

It might be related to USB connection.
By some reason, D435 is connected USB 2.x not 3.x.
Then I modified realsense config to 640x480, 15fps in kaya_hardware.subgraph.json.

Thanks,
