[U-Boot] fw_env.config

[Dimitrios Siganos]

Hi guys,

I's like to ask a couple of quick questions to clear a disagreement we
have at the office.

Is the file fw_env.config needed during compilation time to build u-boot?

Or is it in fact only needed at runtime by the tools fw_printenv/saveenv?

Thank you and sorry if this questions has been answered before.

Regards,
Dimitris

No.

MTD setup in /etc/fw_env.config can be used by fw_printenv/saveenv, but
it depends on compile configuration of these tool(s). fw_printenv can be
compiled with integrated mtd setup and will then not parse the
configuration file.
But yes, the default is to have an /etc/fw_env.config which describes
the mtd setup for u-boot environment. At least this is the case for
distributed versions like in Debian.
