[U-Boot-Users] e1000 problem @ current u-boot

[Andre Schwarz]

Wolfgang,

as far as I can see on the list you sent the latest patches for the
e1000 driver.

My e1000 (82541ER) stopped working on a MPC5200 based board with latest
u-boot.
I have a similar problem on another board ...

Is your e1000 working properly on the latest u-boot ?
Do I need any additional defines or environment settings to get it
working again ?

Obviously it is - again :-[ - my fault or is related to my build system.

Any help is welcome.

regards,
Andre

My patches just added some device ids,

Yes, on a  MPC8548 board. I have not tested it on the MPC5200.

I think there are some known problems with PCI on boards with a MPC5200 
Rev. A processor, e.g. my EEPRO100 card does not work on it. What 
exactly does not work?

[U-Boot-Users] e1000 problem @ current u-boot

Wolfgang,

of course I meant no offense - of course your patch is harmless.

The System (network camera) is running for nearly 2 years now.
Last working version has been u-boot 1.2.x with a 2.6.19 kernel.

Since we've moved to the latest kernel we need a more recent u-boot.

This is what I did - and e1000 no longer works.

Of course I diff'ed the network stuff - no obvious changes at all.
So I wonder if the problem is elsewhere and if e1000 is still working in
general.

As you say this is obviously true - thanks.

regards,
Andre

No problem.

More information could be useful.

[U-Boot-Users] e1000 problem @ current u-boot

[André Schwarz]

Today I've stressed my diff a quite a bit and tried several config 
options from other boards that I did _not_ have ...

After adding the config option for skipping the pci host bridge it 
worked again.
Unfortunately I have no clue why since this can hardly cause that ... 
maybe I'll dig a little deeper.

cheers,
Andr?
