Hello Gene,
hmmm, I should know that because I adapted the
ppc403 support to my helas403 board, but actually...
I have no idea.
I guess, I used the first 64kByte for a debug
monitor and therefore relocated the vectors a bit up
in the memory map. The PPC4xx family has the ability
to relocate the vectors on any 64k boundary.
I don't see any reason to leave it there, so feel
free to remove the ".fill" section. Just make sure
you move the ".vectors" section by 64k.
wkr,
Thomas.
