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
dev: size erasesize name
mtd0: 00080000 00010000 "m25p0.barebox"
mtd1: 00010000 00010000 "m25p0.bareboxenv"
mtd2: 00200000 00020000 "nand0.barebox"
mtd3: 00020000 00020000 "nand0.bareboxenv"
mtd4: 00800000 00020000 "nand0.kernel"
mtd5: 03200000 00020000 "nand0.root"
mtd6: 00800000 00020000 "nand0.kernel2"
mtd7: 03200000 00020000 "nand0.root2"
mtd8: 389e0000 00020000 "nand0.data"

Thank you,
