MPC850 and GDB help

I think I may have confused you a little. When I said running
u-boot from ram, I meant booting it from ram as if it had boot
from flash. Normally, at some point, u-boot _will_ run from ram
by copying itslef there and continung to run. But getting it to
run from ram it's reset vector (first linked address + 0x100) is
totally different.
I'm not sure what you mean by "running Linux from ram". Although
the kernel may reside in flash, it is at some point unzipped,
copied to ram and then runs from there. Someone on this list may
be able to help you more here. Maybe you will have beteer luck
then me getting an answer from these guys. They don't seem to
respond to my questions.:-(
