I have an Xavier AGX attached to a Rogue carrier, but no developer kit, so I was not able to flash anything with the NVIDIA SDK Manager. I installed all the CUDA, VisionWorks, OpenCV, and Tensor packages manually. So this may very possibly be the issue. But anyways, when I tried to run deepstream-app, it says object files are missing then hangs in the terminal. I also cleared the cache. See below:
