Yes, indeed! The warning was trying to let you know that your work flow is
wrong. Flash can be eased in sectors. The env should be in a sector(s) on
it's own. There is no need to erase that sector(s) to re-flash U-Boot.
Erase only U-Boot before re-flashing U-Boot. This will keep all you env
data (which is valuable) intact and the warning will not reappear. If it
does reappear you've done /something/ wrong and the warning will catch
that for you again.
It's a good warning, honestly. Hang on to it. Learn to love it.
Nick.
