I installed via the process mentioned here: https://github.com/IntelRealSense/librealsense/blob/master/doc/distribution_linux.md.

On running realsense-viewer i kept getting messages to update the firmware to >5.10.

I followed the process mentioned here: https://www.intel.com/content/dam/support/us/en/documents/emerging-technologies/intel-realsense-technology/Linux-RealSense-D400-DFU-Guide.pdf

Here is the output of my firmware update process:

Can you please help me regarding this issue. I tried setting the $ export LRS_LOG_LEVEL="" to all possible values but end up getting a 0 byte file.

RealSense support moved to a new forum yesterday (June 10). It is still possible to post here but Intel support staff will not be answering. Please re-post your message on the new forum to receive support from the Intel support team (I do not work for Intel and your question is outside of my knowledge, unfortunately).
