Dear Tom,
In message 20201106204557.GG5340@bill-the-cat you wrote:

Yes. It's intentional that "NOWHERE" means that if this is our run-time location for the environment, then you cannot save the environment. But since we finally implemented the ability to have more than one option enabled and pick the correct one at run time, we build both "mmc" and "nowhere".
But this breaks logic. If you wanna have a nulldev, than implement a /dev/null.
CONFIG_ENV_IS_NOWHERE should be the means to be used when no environment storage drivers are needed / selected, not even /dev/null.
Best regards,
Wolfgang Denk
