 Pressing the same button for at least 10 seconds on power-up will erase the

 This ensures, that you still can recover a device with a broken

 Then you enter the rescue mode, connect to the board with the ncb tool and
 use the following commands to set your MAC address:
 
-  setenv ethaddr 00:00:00:00:00:00
-  run restore_env

 Of course you need to replace the 00:00:00:00:00:00 with your valid MAC
 address, which can be found on a sticker on the bottom of your box.
