[U-Boot-Users] BDI2000 vs Vision-ICE

[Mike Wellington <wellington@lucent.com>]

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.
