Thanks for reaching out.
Well, that's a weird issue. Are you following the Quickstart guide? If you are not, please make sure to follow it: https://01.org/developerjourney/recipe/intel-realsense-robotic-development-kit#steps.
Now, I think you have a problem with your UP Board that is not related to your Intel® RealSense™ Camera R200, I recommend you to contact the Up Board Community (https://up-community.org/) to assist you in a better way.
Have a nice day.
