2016.05 U-Boot Kirkwood - Can't set ethaddr
December 07, 2016 10:27AM
Hi,
I can't change my ethernet address using

root@debian:/share# fw_setenv ethaddr "XX:XX:XX:XX:XX:XX"
Can't overwrite "ethaddr"

I tried even after reboot

When did you try to set this? was it during installation of u-boot and u-boot envs image? or did you wait until after rebooting back into Debian?

During installation of u-boot, I have tried. It gave the same error. Then I searched this forum and someone has same issue and you have replied that the MAC address is random and it can be changed after reboot. So, I have rebooted and tried and still same error.

By the way, leaving the new MAC will make any problems?

vaidyasr,

It will not. It is a local MAC address, so it can only be reached within your network. But if you have multiple Pogo running, this might interfer with certain low level network stuff you might use (normally, the IP address is all you ever have to worry about).

I'll take a look later to see if that was set to be prohibited inside the code. I might have missed setting an option to allow that in Pogo V4. Usually u-boot does not allow users to change it, unless the developer changed this option in the code.

Another way: download a different version of fw_setenv and it might work. At least it worked for me. :P
