Hi
Have you tried enabling
MPC8260 Communication options->FCC Ethernet option-->Ethernet on FCC1, Use MDIO
for PHY-->LXT971 PHY support.
Hope this helps.

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.

You do it exactly the same way like you do it with any other compiler toolchain.
If the tools come with Makefiles and Linker scripts for GNU gcc and ld then
you are set. If not, you will have to come up with your own build rules and
linker commands.
You can check how U-Boot code (especially the standalone programs) gets
linked, but be warned, this is not exactly trivial. You have to understand what
you are doing, and how the linker works.

Wolfgang Denk

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.

Wolfgang Denk

Hi,
My MPC8260 customs board has LXT971 Ethernet chip on FCC1. I am able to
get the linux prompt, but I am unable to initialize ethernet. I have tried
different bootarg options (like setenv bootargs ip=dhcp etc) and
different kernel compilation options (like from make menuconfig, Network
Option->enable DHCP support etc), but none enables the ethernet interface.
Any help will be appreciated.
FYI, the ethernet is working from U-Boot.
Thanks,

The definitions in that file are only usable from inside the kernel,
you can not use them in a user space application.
The correct way to solve your problem (which you did not explain, so
I can only guess) would be to write a kernel device driver for
the peripherial you want to drive, at least if it does not exist yet.
For prototyping, you can play with mmap() on /dev/mem in a user
application, but that is often not very reliable.

Hi,
I found that ADS8260 board enables PHY by the following lines of code
#ifndef CONFIG_ADS8260
/* Enable the PHY.
*/
*(volatile uint *)(BCSR_ADDR + 4) &= ~BCSR1_FETHIEN;
*(volatile uint *)(BCSR_ADDR + 4) |= BCSR1_FETH_RST;
#endif
Our board does not have BCSR. My question is how to enable PHY for MPC8260
based customs board without BCSR?
Thanks,

If your board does not have the BCSR you can just leave this code out.
Usually, you only need to configure which MDII
interface your PHY is connected to and which IRQ it uses. But of course I
don't know how your PHY is wired up on your
custom board.
