Success!! Thanks for the replies. Here's a brief summary of what was

OK. I couldn't find any firmware on the Abatron web-site but fortunately
I've been sent v1.12 from a friend. This seems to make all the difference.

I was able to make some minor progress with the addition of "PTBASE 0xF0" to
my config file (as suggested by Dan) however the key seems to have been the
upgraded firmware in the BDI2000.

I'm not entirely sure the soft breakpoints are working correctly yet (I
suspect they probably are) but anyway I can make sufficient progress using
hard breakpoints for now.

Thanks for the assistance.
