java ClassNotFoundException CodeCoverageActivityProvider during script.getServer("DVTServer.1")

Hi Florian,

What is the target you are using?

Thanks

ki

Hi,

the target is a K2 connected to a Spectrum Digital XDS Pro via LAN. The Java code is running under Linux. 

Best Regards,

Florian.

Note that the CCS Code Coverage tool is only supported on a select few simulators (mostly C6x). It is not supported on any HW target.

Hi,

I don't want to analyze the code coverage at all. I just want to run a functional profile of a already generated tdf.

Best Regards,

Florian.

Can you get the Function Profiler example in .\ccsv5\ccs_base\scripting\examples\DVTExamples\HardwareTraceAnalyzer\tdfExamples to work?

Hi,

yes - it seems to run. Interesting is that is executes the code coverage in case of function profiling. Maybe this is exact the problem since code coverage is not supported for all targets. Can you please check?

Best Regards,

Florian.

The print message may say Code Coverage but the script itself is configured for function profiling. Also when using a tdf file as the source, the actual target does not matter.

Can you zip and attach your script?

Thanks

Hi Ki,

I've attached the java source of the class we use to analyse the trace pod results. But maybe it would be a good idea to find out why the class CodeCoverageActivityProvider  is needed an where it is located...

BR/Florian.

Thank you for the example. I was able to reproduce the issue. Strange, that after the exception the application continues to run and data is exported successfully. I will continue to investigate and keep you posted

Hi Ki,

thank for the response. Anyhow the hardware trace analyzing still does not work for me, the CSV will not be generated.

How could we proceed to debug the problem. 

With the CCS 5.3 this was running quite well, we did it using

TraceAnalyzerSession traceAnalyzerSession = dvtServer.openTraceAnalyzerSession(tdfName, symbolFile);
traceAnalyzerSession.runFunctionLevelProfile(outputDir + fileSeparator + "functionLevelProfiles");

But the API has been changed with CCS 5.5 and we currently are not able to generate these files. 

Could you please tell me how to do this in CCS 5.5?

Best regards,

Florian.

Hi,

I've some more information...

it seems that the trace analyzing scripting is working fine with CCS6 but we'have currently other problems with CCS6 which means that we still search for an solution in CCS5.5...

Any support welcome...

BR/Florian.

I pretty much used the TraceAnalysis.class example you attached (with some slight modifications to match my environment). I did comment out the part where a debug session is started because you don't need one. As you can see in my output, I get the error but the script continues and I get a csv file generated:

I'll see if I can get someone from the DVT team to comment further on the changes made to the API
