I think you can only set/change the mode using BDI, but am not a GDB
expert.

Does your BDI session mention at this point that there are no available
breakpoints?  Before setting a breakpoint in GDB, type "del".  This will
clear any existing breakpoints.  The equivalent command in BDI land is
"ci"

You can use either type in RAM, but you'll find soft ones to be much
more convenient.  You obviously have bigger issues to work through
first.  

Have you contacted Abatron (or your Abatron representative) for help?
They're usually extremely helpful.
