Subject: barebox env userspace
Date: Mon, 3 Feb 2014 17:19:47 +0000	[thread overview]
Message-ID: <4C598A31AEBE214FB619D7F2DC3BD8AB0127A14A86@MSI0E01.MSI.Local> (raw)

Hi,

I try to modify the barebox environment from linux userspace with:

1.	Load environment from SPI NOR flash:
               ./bareboxenv-target -l /mnt /dev/mtd1

2.	Erase environment from SPI nor flash
flash_erase /dev/mtd1 0 0

# do some modifications in "/mnt"

3.	Save environment to NOR flash
./bareboxenv-target -s /mnt /dev/mtd1

----
After reset I can see my modifications in the files within barebox but the changes are not taken into account by barebox.
It's like they are not saved in the persistent storage "dev/env0".(it's like a saveenv is missing).

What am I missing such that the changes to be saved in the persistent storage 'dev/env0' from userspace?

Userspace:
cat /proc/mtd
