It's ok now. Nothing is changed from u-boot-1.1.1. I don't know why.

BTW, does u-boot 1.1.1 for ixdp425 already support ethernet?

You must be doing something wrong. probably  the  init  sequences  as
performed  by  your BDI config file and those used in U-Boot conflict
with each other.

See the BDI2000 user's Manual, and the DULG.

Is your boot device remapped to 0x50000000 on your board? Really?
