It does not. On the ICU862 the U-Boot image is at the  lower  end  of
the enfironment, while the environment is at the upper end (IIRC this
board  uses  top  boot sector flash memory). The environment does NOT
get installed when installing the U-Boot image. So there is  no  need
to put any initialized data in it.

It will be initialized as soon as the user types  "saveenv"  for  the
first time. Until then, the default environment is used.

I'm sorry.
