I'm gonna bug you a little bit more...
Which piece of code was that? (The one you hadn't control over it...) I
understood the reasons why you couldn't remmap all SDRAM to the low
memory, but I'm trying to figure out how you found out about this piece of
code? Is it documented somewhere?
Thanks,
Cristiano.
