Go into the top directory of the U-Boot source and enter
Then recompile U-Boot and update U-Boot on the board. You also should clean the U-Boot environment after having installed the new version because one of the changes is in the default environment.
After a restart, the new default environment will show up. It adds ethaddr to the boot arguments, so you might have to call
or
