Realsense camera d435 fails to stream in Isaac Sight

Autonomous Machines Robotics - Isaac Isaac SDK

Specifications:

  1. Intel realsense camera d435
  2. Ubuntu 18.04 LTS
  3. realsense SDK
  4. realsense camera FW 5.10.3

When I tried to run the realsense camera sample and launch the Isaac Sight, it fails:

$ bazel run //apps/samples/realsense_camera

SO I tried again and this happened:

Hi u3527583,

Because you have slightly different error messages, my tip is not for you.
In my case, D435 which is attached jetson Nano through USB 2.1 by some reason.
Therefore, default configuration for USB 3.x does not meet here.

  1. find out USB speed with your D435,
    lsusb -t
  2. make sure configuration
    realsense_camera.app.json / config / camera / realsense
    I modified both framerate to 15

Thanks,

  1. The response of
lsusb it

:

    |__ Port 3: Dev 3, If 4, Class=Video, Driver=uvcvideo, 5000M
  1. Inside the config file, both framerates are 15

The problem is solved by downgrading linux kernel to 4.18
