Help need: Porting Linux to PQ2FADS_ZU board

Help need: Porting Linux to PQ2FADS_ZU board

[zengshuai]

I use ELDK3.1.1(2005-06-07).
There is a u-boot 1.1.3 and a linux 2.4.25 in the eldk.
I has compile u-boot successfully.And it works good.
I has compile kernel successfully too.(make ads8260_config)
But it doesn't work.

At here,it stoped.
Later,I debug the kernel using bdi2000.
I bi start_kernel(),and setp by setp.
But printk(".........) didn't work.

My board is PQ2FADS_ZU.Does the ELDK not support it?

ELDK is, as the  name  suggests,  a  Development  Toolkit,  i.  e.  a
toolchain. As such, it is independent from the hardware and doesn not
support  any specific board, or, if you like, it supports all boards,
even those that don't exist yet.

What you are asking for is board support in a specific  kernel  tree.
There  is  no  specific  support  for  the  PQ2FADS_ZU  board  in our
linuxppc_2_4_devel  tree   (which   is   included   with   the   ELDK
distribution). On the other hand this is a standard board which which
is probably working fine, but we never tested or varified it.

I guess that it is not configured for use with U-Boot.

Best regards,

Wolfgang Denk
