Hi,
Our board stores the U-Boot environment in an MTD partition. I would like to ensure that there is always an U-Boot environment stored in MTD so that the userspace tool fw_setenv does not need to fall back on its built in default environment or a default environment stored in a file (see https://github.com/sbabic/libubootenv).
When U-Boot starts up it checks whether the specified MTD partition contains a valid environment and loads it. In case there is no valid environment it will use the compiled in default. Is there already a feature in U-Boot which would then also write that default to the MTD partition?
Alternatively a Hush script could help. Is there an easy way to detect that U-Boot is using the compiled in environment? In that case I could simply do a saveenv (?) which would then initialize the MTD environment partition.
Greetings, Mark
