I guess you already know that DDB or none of the other tools can take
the place of h/w assisted low level debug, such as an in circuit
emulator support.

What exactly do you want to debug about the faults ? Does your
hardware have some sort of console ? If so, you could start by
enabling basic console support and enabling good old printf. Its
basically a chicken and egg problem, which you need to sort out by
banging your head on the wall. :-)

anyways, I highly doubt that you could do fault debugging with
anything beyond DDB.

HTH,
