When compiled and loaded with the "imx-usb-loader" to RAM, the command
"saveenv" and "loadenv" do work properly (i.e. "loading environment
from /dev/nand0.environment.bb"). When I flash the barebox to the NAND
with the "barebox_update" command and reboot the device, the message
"environment load /dev/env0: No such file or directory" is provided
during boot. "saveenv" and "loadenv" do not know anything about
"/dev/nand0.environment.bb" anymore and try to access the "/dev/env0".
What am I doing wrong?
