No such warning. Rather than keep you guessing, here's the output on
boot:

Running "env default -f -a" resets the environment and clears out
ethaddr (as well as board_name and board_rev, which can be tricky for
findfdt), though I believe it is already using the default environment
because of the message:

  *** Warning - bad CRC, using default environment

But it doesn't really help with the ethernet changes.

I'm guessing you mean "saveenv" and not "save".

"setenv ethaddr; saveenv ; reset" still fails to work.


I generally try to avoid using saveenv as it makes it harder to test the
default environment when testing a new version of u-boot.
