In the field, you'd probably only use the immutable barebox built-in environment (+ state), but for development, the mutable environment is very handy. > state: New state registered 'state' > state state.of: Fresh state detected, continuing with defaults State looks ok. > environment load /mnt/mmc1.0/barebox.env: No such file or directory > Maybe you have to create the partition. > changing USB current limit to 1300 mA... done > > Hit m for menu or any to stop autoboot: 1 > --------------------------------------------------- > > Why does it try to read the env on a partition on > /mnt/mmc1.0/barebox.env? Is it because barebox.bin also is read from > this partition? Check out omap_env_init(), which registers the environment if system boots from SD/MMC. This seems to take precedence over what's in the device tree. Indeed, upstream AM335x platforms only configure an environment in the DT if it's outside SD, on NAND or NOR. I think placing the environment on the FAT makes sense as the MLO is there as well. Why would you like to move it?
