How can I change the MAC address of the board?
The Micromint Electrum is assigned a MAC address during production from the Micromint block 00:21:a3:xx:yy:zz. This address is stored on the U-Boot configuration as the 'ethaddr' environment variable. To prevent accidental changes to the MAC address, the bootloader console does not allow changing the MAC address once it is set. If you need to substitute the assigned MAC address you can clear the bootloader environment by executing the commands below from the bootloader console. After rebooting, you will be able to change the 'ethaddr' variable. Note that you will need to apply any other changes you made to the bootloader configuration.
