Hello,

Is there a tool to create u-boot environment from text and save into
SPI NOR flash ?

Thank you,
Ran

You'll get some mileage out of tools/env. It's intended for use on a
target so that you can access the target's own u-boot environment from
a Linux userland. I'm not sure if it suits your use-case or if you
want something you can run on a different host.

I need to prepare the environment from text , then create the binary
and then program into spi nor flash.
As I understand now, it seems that this tool can do this.
