I've got two projects, one with ARM side code, and one with DSP side code. I'm trying to write a DSS script to load them both into memory and start debugging on the ARM.

debugSession = debugServer.openSession(".*/ARM9_0");
debugSession.target.connect();
debugSession.memory.loadProgram("dspside.out");
debugSession.memory.loadProgram("armside.out");
debugSession.target.run();

and I get the error

ARM9_0: GEL: File: dspside.out Does not match the target type, not loaded.

If I reverse the order of the two, the armside gets loaded, I immediately break in the debugger at main, and the DSP code never gets loaded.

How do I get around this? How do I get both programs into memory so I can start my debugging?

Hi Adam,

You will need to create a debug session instance for each CPU:

http://software-dl.ti.com/ccs/esd/documents/users_guide/sdto_dss_handbook.html#multiple-debug-sessions-for-multi-core-debug

Example:

debugSessionARM = debugServer.openSession(".*/ARM9_0");
debugSessionDSP = debugServer.openSession(".*/C674X_0");
debugSessionARM.target.connect();
debugSessionDSP.target.connect();
debugSessionARM.memory.loadProgram("dspside.out");
debugSessionDSP.memory.loadProgram("armside.out");

//debugSessionARM.target.run();
//debugSessionDSP.target.run();

// Or you can use the simultaneous run API to run them both at the same time
var dsArray = new Array();
dsArray[0] = debugSessionARM;
dsArray[1] = debugSessionDSP;

debugServer.simultaneous.run(dsArray); // Run CPUs 1 and 2 simultaneously

Thanks

Works, but the scripting console just hangs after i stop debugging. I've tried closing the scripting console and re-opening it, but it just says "Initializing..................................." How do I get control back in the scripting console? The only thing that has worked so far is closing and re-opening CCS.

If the script never terminates, then yes you would see the behavior that you see. It is a known limitation of the scripting console - the inability to force termination of an executing script

Sometimes I'm seeing
No code is associated with "foo.c" line 493 in "armside.out"
when trying to enable a breakpoint
(sometimes even when I was able to previously set the breakpoint in the same debug session!)

I've got armside select as the active project. What's causing this error?

It is hard to say for sure without more details (test case). Usually a common reason for that message is that the debugger is unable to associate the path to that specified source file with the path that is contained in the generated debug symbols that is loaded to the debugger. I assume you are able to able to successfully set that breakpoint when you manually do it via the GUI?

source was out of sync with .out; Are there script commands that will do a build before I loadProgram ?

If running the script from the command-line (outside CCS), we recommend using the below commands:
software-dl.ti.com/.../ccs_projects-command-line.html

If running from the scripting console, you can use the scripting console "buildProject" command (assuming the project has been imported into the workspace). Note that you can call console commands from inside your script as long as the script is run from the scripting console (it will fail otherwise)
