Hi.
I am looking for a command that discards the saved environments,
Does this command help?
=> env default -f -a
I know this command, but it is the manupulation of working RAM in U-Boot.
If I reset my board, it will load the saved environment again.
I want the environment data in a non-volatile device to go away.
I think I'm missing something. As Fabio said env default -f -a will reset it. And then you can saveenv it. If you want to restrict certain parts of the environment check out the stuff around *ENV_FLAGS* and of course if you just want to never have persistent environment, change to ENV_IS_NOWHERE. We don't have a way to tell U-Boot to ignore the valid environment that it did find.
