[U-Boot-Users] the question about u-boot for 1GB DDR-1?

[郭劲]

Hi,Denk,


I resolved the 1GB DDR problem, the reason is that I did not define the
CONFIG_VERY_BIG_RAM. The u-boot-1.2.0 will visit the address above
0x10000000(256MB) if this CONFIG_VERY_BIG_RAM is not defined,then the u-boot-1.2.0
is dead.

Thank you very much.
