Re: [U-Boot] u-boot environment variable storage

[twebb]

 Does u-boot have support for storage of environment variables in
 file form?  For example, in a file on a FAT32 file system
 residing on a MMC card?

 The only reason I can think you'd want to do that is to be able
 to set environment variables in linux user land.  But then I
 have a small brain.  If you do, take a look at fw_printenv under
 \tools\something_or_other


Acutally, I have a system that only contains eMMC flash that is
formatted to hold filesystems of one sort or another, so there is no
spare non-filesystem flash available for the environment.  There is
also no other form of NVRAM on the device.  These are the reasons I
asked about whether the environment could be maintained in file form;
I have no need to set/get environment variables from userland.

Thanks,

Dear twebb,

We don't have any writable file systems, so this would render the
envrionment read-only, which makes little sense.

Short answer: no.

Best regards,

Wolfgang Denk
