AM5728: DSS profiling function fails

Sung-IL

Part Number: AM5728

Dear Champs,

My customer failed to get function profiling data using DSS in AM5728, and the return value of myProfileActivity is '0' in below.

Could you please check below?

debugSessionDSP.memory.loadProgram(LOCAL_PATH + "Debug/AM5728_DSS_TEST_01.out");

try {
debugSessionARM.profileSetup.printActivityList();
debugSessionDSP.profileSetup.printActivityList();

myProfileActivity = debugSessionDSP.profileSetup.getActivity("Profile all Functions for Total Cycles");
myProfileActivity.setStatus(true);

// Set another breakpoint
// var edmaTest = debugSession.symbol.getAddress("edmaTest")
// var bp1 = debugSession.breakpoint.add("edmaTest.c", 56);
// var bp2 = debugSession.breakpoint.add("edmaTest.c", 222);
} catch (e) {
script.traceWrite("ERROR :");
script.traceWrite("ERROR : " + e.toString());
script.traceWrite("ERROR :");
}

Thanks and Best Regards,

SI.

Hi,

What software is this? Which version?

SW is TI-RTOS 4.02.

DSS means "Debug Server Scripting".

Thanks and Best Regards,

Hello,
CCS function profiling is only supported on a limited number of devices and CPU:
processors.wiki.ti.com/.../FAQ_-_CCSv5

None of the CPUs apply to the AM572x. Sorry

Correction, it may be possible for just the ARM9

Hello,

Thanks for your response.
Then, is it possible to implement function profiling for several important functions using tick count and can be displayed it using DSS?

Thanks and Best Regards,
SI.

They can run function profiling for C66X DSP of AM5728 as below.

But, they could not send this data using DSS.

Could you please check their DSS code again?

Thanks and Best Regards,

SI.

The data in the screenshot shown above is not form the CCS function profiler. It is function profiling data from Trace Analyzer:
dev.ti.com/.../

It is possible to script Trace Analyzer via DVT scripting. It has its own APIs. However, DVT scripting has been deprecated in support. The last version of CCS it worked with is CCSv6.2. If the customer wishes to continue with DVT scripting, they will need to use CCSv6.2:
e2e.ti.com/.../670211

Thanks

Hello,

Thanks for your immediate response.
Then, what is your recommendation to get function profiling data using DSS in latest CCSv7/8?
Is DSS still valid on latest CCSv7/8? Or is there any other method and tool?

Thanks and Best Regards,
SI.

If you do not wish to use CCSv6, then the other option is to use DSS to script access to the profile clock:

<CCS INSTALL DIR>/ccsv8/ccs_base/scripting/docs/DS_API/com/ti/debug/engine/scripting/ProfileClock.html

Note that not all CPUs have a profile clock to access (such as M4).

Thanks
