Hi ,
During lunch Nvprov over my Jetson I got follwing error:

[polar_mgbp.cpp@66][2020-Nov-15 14:15:36.017673] <3> : -if inputFile: /home/nvidia/work/xii/daemon/sigdat/xaver-demo-2002b-ball.dat

I tried to solve the issue by using the link https://developer.nvidia.com/ERR_NVGPUCTRPERM but it looks like a solution for desktop and not embedded systems.

The system:
Jepack 4.4
Nvidia Xavier 16Gb

How can I solve the issue in order to be able to perform profiing over this target?

Hi,

CUDA profiling require root privilege.

If you run nvprof on the device, please use $ sudo /usr/local/cuda-10.2/bin/nvprof ...
If you run it remotely, please following below topic to ssh with root account.

Thanks.
