Wandboard Quad FEC MAC address

Postby alxpert » Thu Jul 20, 2017 5:52 pm

Can somebody confirm that the MAC address of the onboard FEC is stored in u-boot for Ubuntu images?
I'm asking this because if i create multiple SDcard from Ubuntu images, they all get the same MAC address.

U-boot manages the MAC address that is given to Ubuntu to use.

You can change it with something like this at the u-boot prompt:
setenv ethaddr 00:1f:7b:b4:0e:01

U-boot retrieves MAC addresses from the system ROM and efuses which are in the i.MX6 chip.
The ethaddr variable is stored on the sdcard along with the rest of the u-boot environment, since Wandboards do not have on-board flash memory.

However, not all OSes use the ethaddr variable.
For some, you may have to edit the networks interfaces file:
nano /etc/network/interfaces

This is more information here:
