Debug Server API Error

Arthi Bhat

I am unable to run a java program that contains the following lines of code:

ScriptingEnvironment env = ScriptingEnvironment.instance();
DebugServer server = (DebugServer)env.getServer("DebugServer.1");
DebugSession session = server.openSession();

A run time error occurs and the following error message is displayed:

Exception in thread "main" java.lang.ExceptionInInitializerError

        ... 6 more

I suspect that there is a path problem related to Debug Server. I have all the proper class paths in place for all the jar files related to the Debug Server.

I need to do a release and I would appreciate a answer to this problem and how to fix it. A code example would be helpful.

Arthi,

You need to specify the target configuration file to use before calling openSession(). Ex:

server.setConfig("C:/Program Files/Texas Instruments/ccsv4/scripting/examples/C64/tisim_c64xple.ccxml");

Have you seen this wiki topic on using DSS from a Java application? There are more details and some example code snippets:

Thanks

Hello Ki,

Thank you for your quick response. I read the documentation you provided and I noticed there is not a file for the USB100 C5505 (USBstk5505.ccxml). There is in the "boards" directory a configuration file called USBSTK5505.xml. My questions are:

1) Do I need a ccxml file for the USB stick?

2) If I do need a ccxml file how do I get hold of one? Is the ccxml file generated and if so how do I generate it?

3) Can you send me the ccxml file?

4) There does not appear to be any documentation related to the difference between a ccxml file and a xml file.

Thanks,

Arthi
