Hi, is there any preferred mode of profiling port code to validate performances after making changes or it all depends on the targeted architecture? I am currently working with Armv7-A and I could not find anything suitable other than Gprof and cycle counting with PMU.

@Matth9814 , There is also Run Time Statistics - FreeRTOS™ , though this is more for identifying task resource usage - not necessarily profiling a specific FreeRTOS-Kernel port.

Thank you for the suggestions and sorry for using this thread for a different question but it is somewhat related to the previous one. I also need to test the same port code and I was wondering if I can just modify one of the available demos for this purpose or if there are some other tests I should…
