CCS/TMS570LS0432: How to jump to the line of the source code using DSS API?

Hello,

Of course the address of the line could be seen within object code and then set PC register to it, using something like

debugSession.expression.evaluate("PC = 0x0001DF64")

A better option would be:

debugSession.memory.writeRegister("PC", 0x0001DF64)

But this approach is not suitable for my goals. I do not know how to receive the address of the line within the Java Script.

So is it possible to do only knowing the line number in the source code file?

Not directly. There are a few more roundabout ways that comes to mind.

The first is to have a label at the desired source line. Then you can look up the address of that label

var addr = debugSession.symbol.getAddress("label");

debugSession.memory.writeRegister("PC", addr);

Another option is to set a source line breakpoint at that address. The you can get the address for that breakpoint by reading the breakpoint properties (see the "BreakpointProperties" class in the DSS API doc).

Ki, thanks for support,

The source code must not be modified, so adding label is not possible.

As I understand the breakpoint properties are created with "breakpoint.createProperties" and all properties set there. However I could only set address directly

props = debugSession.breakpoint.createProperties()

props.setString("Hardware Configuration.Location",0x1df64)

But it does not accept the file & line, like

props.setString("Hardware Configuration.Location","../v_src/Application/StartUp/SystemInit/SystemInit.c, line 63")

If I set breakpoint directly

debugSession.breakpoint.add("../v_src/Application/StartUp/SystemInit/SystemInit.c", 63)

I don't know how to get properties of created breakpoint. Is it possible?

Upd:

I've just found the method to set source and line: setSourceLocation.

But I still do not understand how to read properties from breakpoint.

The following instruction

addr = props.getString("Hardware Configuration.Type.Location.Address")

Causes an error - Could not find property Address

So how to get the address in this case?

Ki,

Yes, it works this way.

Thank you very much!
