Somebody in the thread at some point said:
| great, good start!
| Unfortunately I still don't know what the base address for 0xFF800000
| is. It is pointing into NAND, but where does NAND start?
I think you are confusing NAND with some normal kind of decent memory :-/
NAND is a "peripheral", there are a bunch of peripheral registers at
0x4E000000 that you use to talk to this "peripheral". It is not memory
mapped itself. You send commands to the NAND "peripheral" from one
register, write the address you want into another register and spam the
data out from another.
So any addresses you see about NAND will be offsets inside the NAND
peripheral and not having physical processor addresses.
BTW Pocky told me it is a holiday today
