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