No target exist now that Iam aware of.
The thing that prevent one from beeing written is that the help on the commands
that the
riscwatch probe can do is to poor.
for ex. the help for dump is
---
help dump
dump - upload processor memory in absolute file format
dump -h <addr>..<addr> - upload hp format (requires transfer protocol)
dump -b <addr>..<addr> - send data in binary (valid with -h option)
dump -n <addr>..<addr> - send data in fast binary format

This dose not actually work if you trace a dump from the rwppc program you see
that
a @<memory_type> is also needed.
On the other hand nobody has tried to make the interface difficult so its
probably
quite easy to reverse engineer it.
What you need for gdb is a way to start/stop the cpu and to read/write
registers and memory.
Its only the command for writing that is not obvious from the ascii trace that
I did.
