Oops? Why do you think this makes debugging more complicated? I don't
care where something is mapped, it's the job of the debugger to
resolve those addresses, isn't it?

Are you really trying to run in little-endian mode? Really???
You are not supposed to do that.

We use the Abatron BD2000; it supports the MMU, interfaces to GDB /
DDD, comes with 3 years of warranty on the hardware, _excellent_
support from the Abatron folks, and is cheaper than other solutions
(2500 Euro).
