[tcf-dev] Requirements for mapToSource Command 
Hi!

It took me rather long to get there but I think I am pretty close to visualize the hit of a breakpoint for the first time pretty soon. The thing is that I'm right now a little stuck. At the end of this message you can find the TCF Trace output I got so far.

The first question I got is how the agant evaluates if my breakpoint is hard- or software? As you can see all breakpoints found are declared as "Hardware" which is actually wrong.

My actual problem is that address_to_line() does not get called so far and I am not quite sure why.

One of the last messages I receive is:

426.982 Inp: E RunControl contextSuspended "P40.1" 49358 "Cannot resume. At col 4: Undefined identifier main. Invalid expression" {}

And yet I could not tell what it exactly means, if it actually hints to the exact problem or whether it comes from.

In line_to_address() I've been setting hard-coded breakpoints like this:

    int err = 0;

    CodeArea area;
    memset(&area, 0, sizeof(area));

    area.file = "c:\\users\\falkstef\\runtime-eclipseapplication\\sdccprog\\main.c";
    area.start_line = 46;
    area.start_address = 0xC0C5;
    area.end_line = 49;
    area.end_address = 0xC0CE;
    callback(&area, user_args);

since I don't have access to this information at runtime yet but those values are correct.

Could anybody help me on this? If you need any source-code let me know and I will send it to you.

Best regards,
Stefan
