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

+- red, until you release the button

 This ensures, that you still can recover a device with a broken
 environment by first erasing the environment and then entering the rescue
 mode.

 Once the rescue mode is started, use the ncb binary from the tools/

+have an empty environment, the board comes up with the amber LED turned on.
 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
+  setenv -f ethaddr 00:00:00:00:00:00

 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.
