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?

I compiled u-boot 1.1.1 under cygwin for Coyote board with "make ixdp425_config && make all". I use BDI2000 or Insight to load "u-boot" to the board. It runs well after I commented out below lines in

"cpu/ixp/start.

If I don't comment out this, it will die on "mov r1, #4" or "mov r1, #1".

Can anyone tell me why?

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.

My second question is how to program the u-boot to flash under BDI2000.

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

I've tried to program "u-boot" and "u-boot.bin" to 0x50000000 under

BDI2000.

I can run it under BDI2000 by "go 0x50000000". But after I unplug the BDI2000 from the Coyote board, it can't run (There's nothing on console).

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