Realsense viewer can't find realsenseD455 camera

L4T/JetPack version: L4T 32.3.1

RealSense camera(s): D455

I run the ./installLibrealsense.sh and then ./buildLibrealsense.sh. when it finished ,I turn on the Realsense Viewer and used the D455 camera , but realsense viewer can't found the D455. But when I tried D435 , the realsense viewer work fine. Is D455 not currently supported?

Hey Mingchi-Yeh,

If you look at ./buildLibrelsense.sh, it is trying to install librealsense version 2.32.0. I'm pretty sure the D455 is newer then a year.

I edited the line for the version number to be 2.40.0. I also ran it with CUDA, but only the stereo camera worked for the D455. I'm trying it without CUDA now to see if there are kernel issues.

BTW: I'm running Ubuntu 18.04 on the Nvidia NX dev board.

By the way , I found that D455 need at least librealsense version 2.38.1. maybe

Thanks for your answer ,I tryed 2.39.0 but still can't found the D455 camera. But you can try the 2.40.0. "https://github.com/IntelRealSense/librealsense/issues/7875" That help me solved the quation.

Just to reference a solution I found for the D455, since I had serious issues with the NVIDIA NX Dev Kit: NVIDIA Xavier NX Patch Update Request

This is how I solved the issue of inconsistent messaging. I also edited the build script in this repo to be 2.41.0 (which was released yesterday) and updated my D455 to the latest firmware. Let me know if you try my method and we can compare results.
