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

Dear all

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?

Hi,

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

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.

[U-Boot-Users] eth0: Invalid ethernet MAC address

[kabbin]

Dear Daniel
   When I use "NFS" command in u-boot, I got:

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

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.

Then set it correctly in the environment.

> Can u-boot allow me to change HW MAC address?  

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.

Wolfgang Denk

... FAQ ...

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

Indeed.

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.
