SEVERE: Cannot perform operation, target is not connected.

Other Parts Discussed in Thread: MSP430F2618, CODECOMPOSER

I am new to TI CodeComposer, having only done some builds of other people's stuff for a project I am working on. I need to write a bunch of test scripts for this software. We are running on a TI MSP430F2618 with Code COmposer v5.1 and the USB emulator pod. When I run the example script, I get an error when I try to execute the following line:

debugSession.memory.loadProgram("/Users/rbrown/workspace_v5_1/xPG/Debug/xPG.out");

loadProgram: ENTRY sFileName: /Users/rbrown/workspace_v5_1/xPG/Debug/xPG.out
SEVERE: Cannot perform operation, target is not connected.
SEVERE: Error loading "/Users/rbrown/workspace_v5_1/xPG/Debug/xPG.out": Cannot perform operation, target is not connected.

I can get connected to the target inside Code COmposer, but the script is having troubles. For what its's worth, here is what I get when I try to open the session:

debugSession = debugServer.openSession(".*");
openSession: ENTRY sPattern: .*

I did have to change a few things in the dsp.bat script, as it was apparently trying to use non-existent versions of files. Since I am a Linux/emacs nut, I converted dss.bat into dss.sh so I could run it under cygwin from my beloved xemacs. Just in case I botched something, here is the dss.sh script I use to invoke Rhino:

#!/usr/bin/bash

# dss.sh -- cygwin port of dss.bat, script to run js scripts on TI DSS.

Can anybody help me with this problem? I am stumped at this point.

Thanks! :-)

There should be a line in the script like target.connect(). This is the call to connect to the target. So you see it in your script?

No, not in my script, nor in the example from TI either.

Where does this "target" object come from? I have "script", "debugServer", and "debugSession" objects cloned from the example script, but no "target" object anywhere.

Here is what I get when I try to execute the call you provided:

js> target.connect();
js: "<stdin>", line 19: uncaught JavaScript runtime exception: ReferenceError: "target" is not defined.
js>

Likewise, when I try to invoke the "connect" method from my "debugSession" object, it doesn't know that method:

js> debugSession.connect();
js: "<stdin>", line 20: uncaught JavaScript runtime exception: TypeError: Cannot find function connect.
js>

So where do I get this "target" object from???

An instance of the target class gets created when a debug session is launched. So you would use it with your 'debugSession' object:

debugSession.target.connect();

GOT IT !!!

"target" is a member of "debugSession", so the following works:

js> debugSession.target.connect();
connect: ENTRY
connect: Requesting target connect
waitUntil: ENTRY timeout: infinite
log: Target is now connected
waitUntil: RETURN
connect: RETURN
js>

THANKS !!! :-)
