NAME

       fw_setenv - Tool for modifying the environment for the bootloader U-Boot

SYNOPSIS

       fw_setenv name [ value ]

DESCRIPTION

       fw_setenv  is  a simple tool for modifying the environment for the bootloader U-Boot.  The
       variable name is updated to hold value if it is already set in the environment, else it is
       created  and  set.   If  only  the  name  argument is given, the corresponding variable is
       deleted.  This version of fw_printenv stems from libubootenv and does not hold a  built-in
       default environment.  Instead, the default environment is read from a file.
