Linorobot2: realsense D435i

[Naseef A K]

Sir,
we're testing linorobot2 for our research robot with intel realsense D435i and jetson nano 4GB B01. while launching bringup we didn't get realsense data correctly; we've got these error:-
 [realsense2_camera_node-6]  02/10 13:29:20,255 WARNING [547448928672] (messenger-libusb.cpp:42) control_transfer returned error, index: 768, error: Resource temporarily unavailable, number: 11
with help of some threads we've found that realsense SDK is not installed in our jetson nano, and intel hasn't officially released realsense SDK for ubuntu 20.04.
How can we install that? or is there any other way to get realsense data correctly?
We're powering our realsense, rplidar A1 and teensy 4.0 from jetson nano USB ports is this related to powering issues?

we are able to get camera/* topics form ros2 topic list but inside rviz2 the topic is seen but unable to visualize.

Hey,

Yep, could be power related issue. Try running the sensors on a externally powered USB hub.

could you solve the problem we have the same

The error is not the issue. Jetson is to slow to handle the data, lower your resolution to 424x240x6 and it works, see under issues.

Jetson has been replaced with RPI4, same issue, next CPU board is a gen5 i3 Intel nuc.
