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.
