Yes, sorry, my mistake.

I did reset it, but only on the debugging system, not on the target system.

I tried that too. There are a few additional flags that can be set. Of
particular interest are DCONS_FORCE_CONSOLE and DCONS_FORCE_GDB. I
presume I should set FORCE_CONSOLE to 1 if I want a console over

I'll take a look and see if there are any bugfixes for firewire.
Thanks for the reply!
