Hi,
Now I am working on ESP32 and want to do know which function used much CPU time.
When use -pg to compile project, the xtensa toolchain said: undefined reference to `_mcount'.
How can I know which function used much CPU time?
Thanks.
Is it possible to do profiling (gprof) on ESP32?

Hi yanbin,
Gprof support is in review at the moment, and should appear in master next week or so.

Resurrecting this old thread… it seems it's available these days via https://components.espressif.com/compon ... ssif/gprof -- any experiences with doing it that way? Were the results expected / accurate?
