But this is exactly the point of defining MONITOR_LENGTH: _if_ the
environment shall be embedded in the U-Boot image (ENV_IS_EMBEDDED
will be set), then MONITOR_LENGTH must be big enough to include the
environment; and if the environment shall be in a separate flash
sector, then MONITOR_LENGTH must be small enough NOT to include the
I don't know who designed it that way (because I don't care about the
FADS board), but according to "board/fads/u-boot.lds" the environment
on this board is aligned on a 256kB boundary _after_ the U-Boot
image. So MONITOR_LENGTH must not include the environment, and
ENV_IS_EMBEDDED shall not be set.
