Update of the u-boot default environment

Is the default u-boot environment (which is compiled into u-boot) updated when I perform a full image update (not in recovery mode) with run setupethdate and run update? Or is a explicit, manual saveenv after the update required?

You probably meant run setupdate resp. run setethupdate.

and run update?

Sure, why not? It does flash the U-Boot binary after all which has that compiled in. Note however that currently the user space fw-utils’ default is built into that binary which needs separate updating.

Or is a explicit, manual saveenv after the update required?

As described in the flashing instructions we do not by default alert any of the customer’s potential valuable active U-Boot environment but you may manually do whatever you desire.

Right, run setethupdate and run update. My custom u-boot default environment is updated like expected.
