Accessing the same target using CSS and CCS GUI

Other Parts Discussed in Thread: CCSTUDIO

Hi,

I am developing JAVA code using CSS to access the TI EVM for C6472. I am using the onboard XDS100 JTAG emulator. It all works fine if I use the stand-alone CSS server (without CCS GUI).

I now need to use the CCS GUI at the same time as my program to debug the DSP. I am using the instructions provided at http://wiki.davincidsp.com/index.php/Debugging_Your_DSS_Script_Using_CCStudio_v4 to update my JAVA code.

However I don't manage to start the CCS GUI.

Here is the code I am using:

        m_dssScriptEnv = com.ti.ccstudio.scripting.environment.ScriptingEnvironment.instance();
        try {
            m_dssScriptEnv.traceSetConsoleLevel(com.ti.ccstudio.scripting.environment.TraceLevel.ALL);

            CCSServer xxx = (CCSServer)m_dssScriptEnv.getServer("CCSServer.1");
            xxx.openSession(".*");

        } catch (ScriptingException e) {
            e.printStackTrace();
        }

And here is the output I get:

getServer: RETURN com.ti.ccstudio.scripting.CCSServer@1f8247d

WARNING: CCSServer.openSession() failed. DSS was unable to launch Code Composer Studio, however script execution will continue. java.lang.ClassNotFoundException: org.eclipse.core.launcher.Main

I am using Eclipse Java EE IDE build id: 20090920-1017 to run my JAVA program.

Thanks,

Hello,

If you're writing custom Java code, you'll need to add <ccsv4\eclipse\startup.jar> to your classpath for this to work. If you take a look at <ccsv4\scripting\bin\dss.bat> you'll see all of the command-line arguments that need to be passed to Java.exe.

Thanks,

Mike

Thanks Mike. I updated the wiki topic to mention the additional JAR file needed.

Thanks, it's now working!

It's very slow. About 3 minutes to start CCS GUI and 1 minute to start the debug session. Is that a feature of the XDS100? I have an XDS510 also, would it be faster with it? (Can't try it yet, as I am waiting for a full licence of CCS).

I have noted a couple of things that could be improved. Not sure where to put it:

- I get disconnected from the target when I use Skype with USB headset.

- I can only open one memory window in CCS GUI. That's a bit restrictive and it would be better to be able to open as many as I want.

Thanks,

JP,

XDS100 is definitely much slower on C647x than an XDS510. There is an XDS100v2 coming out that improves speed, the one on your board is a v1. There are also some improvements in CCSv4.1 that speed up debug launch time. 3min to start the CCS UI is very slow though, I wonder if you are running out of memory, for me it is typically up in 10sec.

I have seen issues where plug-ins can slow down CCS startup as well. I remember having a plug-in from Rational installed a couple years back that was trying to talk to a server on startup and it was killing my startup time. Don't remember which one it was.

Regards,

John

You can open up multiple memory windows. Use the 'New Memory View' icon:

Hi,

Our application actually requires us to start the JVM from a Windows Executable and run the JAVA program from there. When I do that CCS UI starts in 20 seconds. It's only if I start it from Eclipse that it takes 2-3 minutes... So this is not a problem for us anymore.

I am using CCS4.1.

Thanks for the great support!

Thanks for the tip about the Memory view. It will make my life much easier ;¬)
