CCS/MSP430G2553: Issue working with DSS Script

Rakesh Modi
Expert 1680 points
Part Number: MSP430G2553

Tool/software: Code Composer Studio

Hello,

I am trying to prepare a DSS script to verify various functions of firmware. Till now everything was working good, but suddenly I am facing a problem to set the variable value. The expression

var temp = 31;

debugSession.expression.evaluate("i="+temp)

does not set the value i to 31. Even if it sets, but when I give "debugSession.target.run();" instruction, the script behavior is not as expected and does not show the result as per variable set in previous instructions.

Please help me to resolve this issue.

Thanks,

Rakesh Modi

    Hi Rakesh,

    Based on your small code snippet, I don't see anything wrong. Everything works in my environment. Make sure that the target is halted and the variable is in scope when you try to evaluate the expression. If you are still having issues, please provide a small test case. This would include the dss script and the project it is for.

    Thanks

    Hello Ki,

    Thanks for your reply. I am not able to send the entire firmware, but here I have attached c file, which contains functions on which I want to run attached DSS script.

    The issue is "debugSession.target.run();"  statement does not give expected output, but "debugSession.target.sourceStep.over();" statement gives proper result. In both the case breakpoint is at the same location. So I don' understand the reason behind this behavior. Please see attached C code and DSS script.

    Rakesh Modi said:
    The issue is "debugSession.target.run();"  statement

    Are you talking about the call in line 69 of the script? If your replace it with a step, it works?

    Also please enable full verbose logging and provide the generated log after your try to evaluate the expression.

    Thanks

    Hello Ki,

    Yes, I am talking about the line #69 in the script. Yes, if I replace it with step it works. I have attached a log here for failure case. Let me know if you require more information.

    Hi Rakesh,

    I took a look at the logs. I do see that the test failed. But it looks like the expression was evaluated correctly. The root cause of the failure is likely not because of the expression evaluation.

    To debug further, I would need a test case. It doesn't have to be your actual application, source files, and script. Something stripped down and simplified is fine.

    Thanks
