View CPU cycle count while debugging ?

[geoff_s]

Is there a way to see the cpu cycle counter while debugging with Kinetis Design Studio ?  I wanting to quickly check the number of cycles required for some instructions in my code, without resorting to techniques like systick or toggling external pins.  This was something I vaguely recall I could do in CodeWarrier.

Hi Geoff,

this is because CodeWarrior comes with a built-in trace viewer and support for hardware trace, while something like this is not present in KDS.

I may suggest you refer these two thread for workaround:

KDS trace capabilities?

Kinetis design studio Trace and Profile

can this help you?

Have a great day,
Jennie Zhang
