I don't have a Jeeni target, so Grant is the person who can help you with that.

I would try "set rdiromatzero true" as it is a quick test.

Another thing you can do is to turn on Grant's RDI trace facility:

Something like

maintenance rdilogfile /dev/tty
maintenance rdilogenable on

Would print the message exchange between GDB and the target.

Do this after the load or you will have too many messages!


BTW, your program may have been linked with the wrong load address.
What is the value of the PC  (P/x $pc) after the load?

Okay, I don't think there was complete agreement on the syntax and the
semantics, but here's a stab at what I think was agreeable to most...

Proposed Interface:

    pathmap add <from> <to>

	append a mapping from directory <from> to directory <to>
	to the current list of mappings.

    pathmap delete <optional-list>

	delete the mappings indexed by <optional-list> from the
	list of known mappings.  All subsequent mappings move up
	the list.  (For example, if you delete mapping 2, then mapping
	3 becomes mapping 2, mapping 4 becomes mapping 3, and so on.)

    pathmap list <optional-list>

	list the specified mappings.  If no list is given, all
	mappings are listed.

and potentially:

    pathmap insert <index> <from> <to>

	As for 'pathmap add', but insert the mapping immediately after
	mapping <index>.  All subsequent mappings move down the list.
	If <index> is zero, then the mapping is inserted before the
	first mapping.

Where:

    <from> and <to> are directory path prefixes 

    <optional-list> is a list in the same format as for the
		breakpoint commands

    <index> is a non negative integer

And the mappings are not regular expressions -- that is left as a
potential enhancement for the future.  Also, I'm unconvinced of the
need for the "pathmap insert" functionality.

Comments?

Well, I like it this way.  It does not hurt the CLI language at all
so if you are looking for an "approval in principle" or something like that
consider it given.  I will not pest you with requests to change the command
interface anymore :-)

I can only answer for the CLI aspects though.  But I understood that people 
liked the idea of having this around, so if I did not misunderstood I believe
everybody is sort of waiting for the patch already.

The "insert" operation is interesting.  I think J.T. gave a good example of
a situation where it can be useful.  But I guess it is a simple thing to add
at any time, so we may test the concept by initially not providing it and
seeing if someone asks for it (out of a personal need) or even send a patch.

IMO you should go ahead with this and submit a patch.

Thanks, but I stand by my comment --- You didn't see what went into
that draft.  I spent a lot of time writing (and re-writing) it until
it reflected what I wanted to say.

Eh?  Those chapters are in the internals document, this is intended to
be user documentation.

Hi
i am still not able to execute the program on the target boeard .
As soon as i give 'cont' , everything goes for a toss .
i am also not able to single step it ..when i give info target command , it
says "Target does not support single stepping " .
But , when i tried by using "stepi" instruction it at once moved into some
"warm-reset" assembly code ..& from there to "start" code and startted an
endless loop there .
i think that it is not able to initialise even ..
any guesses where the problem may be .
i enabled the rdilogfile , but i could'nt figure out anything from it ..
i am attaching the log file , hoping some of u may help me in this regard .

thanks
danish.
