No, since we have no idea what the bug is.

You could certainly hack it to; I don't know if it would be
generally
useful.

Use a third-party program which converts RDI to the GDB
remote
protocol.  There's at least two; one formerly distributed
by Cygnus
that you can probably still find (I'm afraid I don't
remember the name)
and one in CodeSourcery's ARM releases, which are publicly
available.
There might be others, too.

Fernando,

Do you know anything about this Cygnus GDB/RDI translation
utility?

I looked into the CodeSourcery utility, rdi-stub. It
requires a
dl-solib (SORDI) that consumes the RDI data. The only one I
know of is
ARM's Armulator. I need one that communicates with a TCP
port, but I'm
not sure one exists.

Cheers,
Shaun

You're supposed to have one of these from wherever you got
the RDI
device.  The DLL interface is the only one ARM supports or
documents,
as far as I remember.  What it actually speaks looks like
ADP, the
underlying proprietary protocol.

It's possible that I am mistaken and the ADP DLL is
supposed to come
from the ARM tools rather than the device.  I'm not sure
what to
suggest, then.  You may need to ask EPI about this; their
FAQ hasn't
been updated in years, but does reference "target
rdi".
