I'm trying to debug my CUDA application to solve an unknown code bug related to copying data from device to host.

I've tried to configure the Nsight debugger, but this is what I get in the Local window in debug mode:

The variable dev_data is the device variable on my GPU.

I searched all over the internet but didn't find any solution that will satisfy me, everyone says that I need to copy my data back to the host, but I need to watch my variables directly on the GPU.
