ARM - RDI ethernet support

ARM - RDI ethernet support

[Dave Vogel]

Does any one know if Insight supports the ARM RDI protocol over
ethernet?  I know that GDB supports it.  I am successfully able to
connect to my target (using a "JEENI ICE") by opening a console window
and issuing the GDB target command "target rdi e=xxyyzz".  However,
things such as "Ctrl-C"/Stop to force my target to halt doesn't seem to
work.  Thanks in advance for any help...

Dave,

The code that gdb uses to do ARM/RDI over UDP is all code that ARM
contributed.  It does not use the main GDB TCP/IP code.  The ARM code
was originally incorporated to provide serial support for the ANGEL
monitor, and it has been tested to some extent for that purpose.  The
UDP code just came along for the ride.  It has not been extensively
tested by anyone here at cygnus.  I don't know of anyone else who has
used it much either.

At present, I don't think we have a way to test this, but if you can
fix any of the bugs you are seeing, we will be happy to help get the
patches into the main line of gdb...

Hi Dave,

Thank you for your patches.

I will incorporate the Tcl part of it soon, so we will be able to select
RDI over UDP on Insight.
As soon as I find some time, I will try to figure why pressing the STOP
button does not work.  Note that it will be somewhat difficult for me as
I don't have an interruptible target on hands, but I will at least check
if interrupt_target() gets called.

With regards to the interrupt patch to ardi.c, we have already
incorporated a patch from Grant Edwards that does the same thing.  Due
to my vacations and the difficulties I have to test (lack of ICE
target), I had no time to incorporate it in the snapshots, which I was
planning to do this week.

I am attaching the current patch and I would appreciate if you give it a
spin.  If you have any problems please let us know.  We can try to merge
the two patches (I don't think it will be necessary though).

Regards,
Fernando
