Why don't you just overwrite the settings in the running system using
the setenv command?

Don't use dirty source. Always use clean sources only :-)

If I understand correctly, the Ocotea board stores the envrionment in
NVRAM. Once saved there, it does not matter  if  you  install  a  new
U-Boot   image  with  a  different  default  environment:  the  saved
environment in NVRAM is valid, and will get used.
