RealSense D455 not being Detected on Jetson nano

[harshal-14]

librealsense	2.55.1 RELEASE
OS	Linux

I followed this procedure

The complexity of the MIPI driver installation instructions is aimed at developer teams rather than individuals. I would instead recommend trying to install the librealsense SDK using the simple libuvc backend build script at the link below in order to bypass the kernel and make the librealsense build not dependent on a particular JetPack version.

and even build it from source but realsense-viewer seems unable to detect the board.
Kindly help debug this issue.

Camera is detected by lsusb but not by librealsense2.

So I was able to make it detect after purging

dpkg -l | grep "realsense" | cut -d " " -f 3 | xargs sudo dpkg --purge

However it is still not able to get the IMU(Motion module) checked from realsense-viewer. It stops other streams too if I enable Motion Module stream first. And suddenly it went back to not getting detected again

Alright I solved this by downgrading the firmware to 5.15 followed this article:

https://community.intel.com/t5/Items-with-no-label/Downgrade-RealSense-Firmware/m-p/582488

And then rebuild using

https://github.com/IntelRealSense/librealsense/blob/master/doc/libuvc_installation.md

For line 46 I changed it to have this

cmake ../ -DFORCE_LIBUVC=true -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true -DBUILD_WITH_CUDA=on -DFORCE_RSUSB_BACKEND=TRUE

Works like a charm after this. Thanks to the previous github issues that helped me solve this one.
