    2020== Restoring defaults
     21The Newport boot firmware has a copy of the original U-Boot env that was created during build time.
     22
    2123To restore default bootloader environment variables:
    2224
     
    2527- Execute the following command:
    2628{{{
    27 env default -f -a
    28 }}}
    29 - Because the bootloader queries the EEPROM for the contents of the variable "prompt" and defaults have been restored there will be no "GW6xxx-xx>" prompt until the EEPROM is queried again on reboot, this results in a blank line with no prompt.  On the blank line type:
    30 {{{
    31 saveenv
    32 }}} 
    33 - Reboot the board
    34 {{{
    35 reset
     29run restore_env && reset
    3630}}}
