Only now it becomes clear that you are not talking about Linux at all.

Your posting is off topic in the linuxppc-embedded mailing list.

Chances for useful  replies  are  much  better  in  the  u-boot-users
mailing list instead.

Chances for useful replies would be even better  if  you  provided  a
little more information. "modify several line of ..." is not really a
precise description of what you did.


Porting U-Boot to new hardware requires more  than  just  tweaking  a
line  here  and there. It will require both an in-depth understanding
of the hardware and U-Boot.

Did you read the README that comes with U-Boot?

Finally: did you order your BDI2000 yet? You will  probably  need  it
soon.


Best regards,
