when I set the local address map:

0x00000000 - 0x0FFFFFFF for DDR2 256M

0x10000000 - 0x4FFFFFFF for nandflash 1G

the P2020 board won't work correctly.

but, when I set:

0x00000000 - 0x0FFFFFFF for DDR2 256M

0x40000000 - 0x7FFFFFFF for nandflash 1G

there have a 744M memory gap, then the board will work normally.

it seems that the space must be aligned.

Can you explain it for me? thank you!
