People at my place of work are telling me that the
Vision-Ice supports "backtrace" and the BDI2000 does
not. I looked on the Abatron website and it doesn't
say. Can anyone confirm or deny this?
By "backtrace", I mean the ability to set a breakpoint,
hit that breakpoint, and be able to see the last N
instructions executed.
