I am using the cross-compilation method to develop and profile my application on Jetson dev-kit - as explained in the following link: http://devblogs.nvidia.com/parallelforall/nvidia-nsight-eclipse-edition-for-jetson-tk1/
In the simple case, I can run the visual profiler on the host to get the overall GPU usage without any problem. However, when I try to use the “Examine Individual Kernels” option to get more detailed information, I get non-stopping error signals regarding some fifo operations and the process doesn’t terminate unless I stop it manually. Here is one of such signals:
“gk20a gk20a.0: fifo_error_isr: channel reset initated from fifo_error_isr”
Can anyone please explain what is causing this problem and if there is any work around? or if there is a way to run the profiler directly on the board itself? I know that I can use “nvprof” on the board to get general performance metrics, but I don’t know how to do it to collect more detailed information (similar to what “Examine Individual Kernels” does)!
I would appreciate any suggestion.
