I was modifying the '/init/general' file, the line:
global.boot.default=nand
A second method (this one worked): changed the content of 'boot/nand' file.

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
