Unable to count event in Cortex R4 using PMC

Hi,

I am trying to set the event counter register to count particular event using ARM Cortex R4's performance monitor register.

I followed the steps as in this link..
http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.faqs/ka4237.html

But it is not counting the events which I set. Only the cycle count is working. I am using RVDS 4.1 prof.

Does RVDS support event counting or is there any configuration error that needs to be corrected?

    Hi,

    I am using the ISSM. Yes it just models the cycle count but not the PMU.

    Is there any other tools/simulators available that model PMU for any cortex R or any cortex A series processors?

    Thank You.


    What target are you connecting to? 

    If you are using the models what ship with RVDS, these do not model the PMU counters (except the CCNT - I think).
