Hi,
Yes I just opened new thread here since other thread was old. in this case on AGX Xavier user have not installed any SDK stuffs.
What I tried just to confirm is flashing Stock BSP on my emmc Module, and I got the same result. I will try on devkit and ask user as well to try.
But one difference I have seen is compared to Xavier NX (Issue installing CUDA -SDK manager cannot connect to the Jetson NX and host USB not working - #15 by WayneWWW) is I see Active: failed when I check service status even with stock BSP
