I am attempting to profile some code on the beaglebone with a AM3359 processor. I have installed the SDK provided by TI and recompiled the kernel (3.2). I am trying to profile with ARM Streamline but it provides the following error:
ARM Processor PMU event counters have been detected, however the event counters are reading zeroes. Event counters include those counters listed in the counter configuration options dialog under the core name but exclude the cycle counter (Clock:Cycles) as it is controlled by a dedicated counter. It is possible that the PMU configuration bit DBGEN has not been enabled, and counter values subsequently will always read as zero. To remedy, please update your firmware or Linux kernel to enable DBGEN.
I am able to view the cycle counter but none of the other counters (cache, memory, etc). Is there anyway to enable the DBGEN bit as indicated in the error?
Thanks, Eric
