As far as I know the gdb v850 simulator target is just a v850 core instruction
simulator and can't be used with programs that interact with hardware.

As for the RedBoot I posted some patches to make it run on CEB v850SA1/SB1
on ecos-patches march 2003 list, but I think that if you started from that
target than there is some more work to do to make RedBoot and eCos run on
v850E/MA1 based boards.
