Do we think that the best orientation is facing forward?
I think facing forward is the most stable and most tested configuration. There are some recent changes in the librealsense
library to improve some existing issues with downward-facing configuration, so maybe the user can update to the latest version and see if it helps.
I hope we don’t need to flash the system since we want to keep some existing work.
As long as you can install all the required packages it should be ok
realsense-viewer
to see all messages from librealsense
and inspect the problem. If it's something specific, it would be better to create an issue on their repo https://github.com/IntelRealSense/librealsense
