uEnv.txt in UART boot.

In UART boot the default MAC Address is automatically set.

I have created a uEnv.txt file for setting the right one but I get:

Warning: egiga0 MAC addresses don't match:
Address in SROM is         ec:43:f6:40:84:91
Address in environment is  xx:xx:xx:xx:xx:xx

How can I fix this in UART boot ?

Try setting it at u-boot prompt

setenv ethaddr xx:xx:xx:xx:xx:xx

The same behaviour.

OK. I was hoping it would behave differently. Apparently not.

You will have to either set it explicitly in /etc/network/interfaces in Debian. Or flash the new u-boot, and then set it with setenv (in u-boot) or fw_setenv (in Debian).

Thanks bodhi.

How shoul it like interfeces ?

Right now I have:

auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
    hwaddress ether xx:xx:xx:xx:xx:xx

This does not work and reports the same error as before.

auto lo eth0
iface lo inet loopback
iface eth0 inet dhcp
    hwaddress ether xx:xx:xx:xx:xx:xx

When you have the MAC address in this /etc/network/interfaces, Debian will reset the MAC address while the system boot. So after booting with kwboot into Debian

ifconfig -a

So you should see the MAC address actually being used in the output.

It seems that the MAC is correct now:

ifconfig -a

The Router is now reading the right MAC.
Thanks
