Configure
Edit boot options
By default the barebox has predefined 4 boot configurations:
- nand-legacy-ubi
- Load kernel (nand - kernel)
- Attach rootfs (nand - rootfs)
- nand-dtb-ubi
- Load kernel (nand - kernel)
- Load device tree (nand - bareboxenv)
- Attach rootfs (nand - rootfs)
- net-legacy
- Load kernel (tftp)
- Attach rootfs (nfs)
- net-dtb
- Load kernel (tftp)
- Load device tree (tftp)
- Attach rootfs (nfs)
The boot configuration files include option such as kernel and rootfs name and paths (can be edited)

# list of boot entries. These are executed in order until one
# succeeds. An entry can be:
# - a filename in /env/boot/
# - a full path to a directory. All files in this directory are
# treated as boot files and executed in alphabetical order
global.boot.default=nand-dtb-ubi

global.boot.default=nand-dtb-ubi
Set correct DTB file based on module configuration
This is important when booting with Device Tree.
