Profiling with TMS320VC5505 on EVM5505 and CCS4

Hello,

I tried to configure Profiling like described here:

http://processors.wiki.ti.com/index.php/Profiler

But I have the problem that the processor runs at ultra low speed after activating the profiling functions

Does somebody have an idea or is it a known problem?

 

I`m irritated about the fact, that the possiblities on the point acticity in the profiler setup look a bit different, too.

I see only the checkbox "Profile all functions for CPU cycles"

So it is impossible to me to set Code Coverage active like described here http://processors.wiki.ti.com/index.php/Code_coverage

    Code Coverage is only available when using certain simulators it is not available when profiling on hardware.  

    As far as profiling speed I am assuming you are profiling on hardware, if this is the case the way the profiler works is that it sets breakpoints throughout your application so yes it is going to run a LOT slower.

    Ok so far, so I measure speed with timers ... :-)

    And when I understand you right I have to just look at the cycles operations take in Profiling mode and keep in mind that a cycle should take 10ns running at 100 Mhz
