I’m trying to profile my Qt5 (prebuilt 5.12.8 from apt) application running on my Jetson Orin Nano.
My host platform is an Ubuntu 20.04 machine with kernel 5.15.0-84 and Nsight Graphics (for embedded) version 2023.2.0.0
The target platform is a Jetson Orin Nano running Ubuntu 20.04.6 (kernel 5.10.120) installed this morning via SDK manager.
After starting the application and then pressing “Capture for live analysis” will always end up Qt5 application crash with following message “Connection error detected communicating with target application. Shutting down connection.”.
This topic is extremely similar to my case but does not solve my issue: https://forums.developer.nvidia.com/t/cannot-profile-qt5-application/70607
You can find attached a simple code that reproduces the issue on my system.

When attaching gdb to running Qt5 application before starting live capture and then starting it, the gdb backtrace shows that the crash happens inside Nvidia driver libraries:
