Hi Bob,

While I'm not familiar with the 5208, isn't dBUG in Flash, not SDRAM?
Once it stops running (by passing control to Linux) then any RAM it was
using should be fair game, provided that all its hooks (interrupt
vectors etc) are removed (which they should be).
My first reaction was "Duh! Why didn't I ever question this.
I believe that amongst other things, the dBUG stack is near the bottom of
SDRAM. So, it becomes a bit of a philosophical question: What do we want to
happen when uClinux is shut down? Return to the dBUG> prompt?
In the early days of uClinux on ColdFire that is exactly what
you could do. But that functionality is long gone now.
The 0x20000 gap leaving the dBUG ram intact is a left over
from that though.
