How to access uboot environment variables from Linux?

[Bizhan Gholikhamseh (bgholikh)]

I am aware of fw_printenv and fw_setenv. But they are uboot utilities,
and I am trying to access the parameter from Linux, what am I missing?
Thanks,
Bizhan

Have you not discovered internet search engines?
If you paste the original question ("How could I access the uboot
environment variables from Linux?") into Google, you get the answer as
the first result:

I think you will have to write a program to access and decode u-boot
environment setup format in linux.
If you come across some open source app for this, plz. share with me. It
should be a standard method but typically a small optimization if you
want your main code to be independent of the boot loader your are using
or if you have common code base which works across multiple
processors/multiple loaders.

All,
How could I access the uboot environment variables from Linux? For
example I would like to access the "serverip"
and change that to a different ip address during run time.
 
Many thanks in advance,
Bizhan
