Improvements to quality, usability, and scalability
If you are installing on a Linux system, by default the tool will change ownership of all the files in the installation directory. You can use the nochown switch to avoid this behavior.
The Nsight Systems 2018.3.1 package is for profiling on x86 targets. To profile on Tegra targets you will need the Tegra version. You can download that package as part of JetPack - JetPack SDK | NVIDIA Developer
Hello,
Since you are trying to connect to the Tx2 board, you need to use Tegra version of the tool (as Holly suggested). When using the Tegra version, could you enable the verbose logging and share the log file?
To enable the logging, please rename nvlog.config.template file (in Host-x86_64 directory) and restart the tool. After you get the error message, close the tool. The nsight-sys.log file should appear in current directory (Host-x86_64). Please share this log file.
