Dear All
I faild to mount NFS, but TFTPis fine in U-boot.

//**************************************************************
eth0: SMC91C94 (rev 9) at 0xc4858300 IRQ 188 [nowait]

How can I use the correct MAC address?

I have read the FAQ, so maybe there are some problems on linux kernel side.

But I still have no idea how to deal with it.
Could someone help me please?

Dear all
I reference to
http://blackfin.uclinux.org/forum/forum.php?thread_id=2299&forum_id=51

u-boot has "eeprom" command ? But I cannot find it!
as I got MAC addresses don't match.
Can u-boot allow me to change HW MAC address?

Best regards.

Hi,

No, you must erase the flash region where the MAC address is stored.

Post by kabbin

Set it. Either in the driver, or in user space.

http://www.denx.de/wiki/view/DULG/EthernetDoesNotWorkInLinux

Indeed.

But I still have no idea how to deal with it.

Maybe you should read the ARM mailing list archive. And follow the
advice you there on your posting on that list.

And stop posting the same questions to several mailing lists. That's a
violation of netiquette.

Best regards,

Wolfgang Denk

u-boot has "eeprom" command ? But I cannot find it!

The set of available commands depends on your board configuration.
Probably the eeprom command is not selected in your board config
file. Eventually there is even no EEPROM on your board at all. We
don't know - it's your hardware.

as I got MAC addresses don't match.

Then set it correctly in the environment.

Post by kabbin

Yes, on some systems.

eth0: Invalid ethernet MAC address. Please set using ifconfig

But this won't help you. You still need to implement a way that the
Linux driver sets a correct MAC address. Solutions have been posted
on the ARM mailing list. See the links and suggestions provided
before.

Your reply does not answer the OP's question and is incomplete or
wrong.

The OP asked about the hardware MAC address, but you are probably
talking about the "ethaddr" environment variable, which is a very
different thing.

Also, if the "ethaddr" is write protected or not depends on your board
configuration.

Dear Daniel

Warning: MAC addresses don't match:
HW MAC address: 00:00:00:00:00:00
"ethaddr" value: 00:50:C2:42:B2:62

How can I find the right flash region where the MAC address is stored ? (and then modify the data)
Do I need rebuild u-boot or linux kerenl?

Best regards.

kabbin,

I already answered you on linux-omap-open-source and you ignored my
reply. Why? Again, more detailed. Your omap2420h4 board uses smc91x
compatible chip. This chip uses 128bit serial eeprom to store
configuration. This configuration includes MAC address. Default
configuration is load after chip reset. In U-Boot, you set MAC address
directly into LAN registers (ethaddr), but eeprom remains unprogrammed.
Linux driver resets chip. Program eeprom with valid MAC address. See for
example board/voiceblue/eeprom.c source.

Best regards,
ladis

Forget his reply. It was plain wrong and does not help you at all.
