[U-Boot] Copying default environment to NVRAM

[U-Boot] Copying default environment to NVRAM

[rory]

Is there some flag or normal way to get the default environment that is 
in RAM to get written to NVRAM? I'm currently going to put a routine in 
our preboot code to do so, but was wondering if there was an officially 
sanctioned "right" way to do this. I've looked thru code and FAQ's and 
the best I can find is to run "saveenv" from the CLI, but that's not 
really a good solution.

thx

Why not? What's wrong with a simple command? I'm not sure what you are
looking for?

[U-Boot] Copying default environment to NVRAM

It needs to happen automagically, w/o typing anything. I was wondering 
(I couldn't find anything) if there was some flag that I could set to 
make it happen, rather than modify my boot process to automagically do 
it for me.

Well, than run it automatically, without any typing.

U-Boot is extremely flexible and easily supports such operations, too.

That's an oxymoron. Above you request: "It needs to happen  automagi-
cally", and now you claim you do NOT want to modify the boot sequence
"to automagically do it".  What exactly is it what you want?

Best regards,

I can add this operation to my boot command or to my preboot. However, 
if there is a supported, suggested way to do this, via a #define or 
compile flag, I would like to know because I would rather do it that way 
than put in a "hack".

thx

Adding this (probably even as a self-deleting) commnd to preboot is in
no way a hack. It's a perfectly legal use of a well-documented
standard interface.

There's an old proverb that says just about whatever you want it to.

Thanks. That's what I wanted to know.
