Hi,

I did not understand the question fully,
But if you want to measure for example a function how long it take to finish
you can steup a timer with a high reslution
and start the timer before the function call and capture the time
and capture the time after the function finish.

Hi,

I think the question was: How to display the clock cycle counter (CYCCNT) register in the gdb debugger? I am facing the same issue

Add the contents of the attached System View Description to the svd for the processor you are using. Enable the CYCCNTENA in the CTRL register. Assuming the cycle count register is implemented in the MCU you are using, you are good to go
