Profiling on e200z7 (MPC5777C)?

Hello guys,

Do you have any example profiling on MPC5777C using the e200z7 PMU? 

From what I understand the flow should be something like this:

  • enter supervisor mode
  • freeze counters
  • clear counters
  • set up events (in my case Ref:1 - processor cycles)

  • enable counters
  • [code to be profiled]
  • get values of counters
  • get difference in cycles

I'd be great if you could direct me to an example of PMU.

Thanks in advance!

Razvan.
