Hello Sergei
This worked - I manged to run gdb
So what was wrong with my first application? I did not change any settings
in the config tool, just used a default configuration. You will see that I
am still getting 'Ignoring packet error' and it seems to take quite a while
to download.
THnaks for you help so far  - what could be wrong with my original
configuration?
