How to get Cycle Count in FVP Corstone SSE-300 Ethos-U55?

Archith over 1 year ago

HI, It seems that FVP Corstone SSE-300 Ethos-U55 does no longer has the parameter "Cpu0.has_pmu" which is used to get cycle count (I Used --list-params to see all available parameter and this parameter is not there). Is there any other parameter that can be used to get cycle count? or is there another way to get cycle count? Need Help.
