This section describes the Yocto configuration needed to integrate with the GRUB bootloader, which is most commonly used on x86 based systems.
You can enable Mender integration with GRUB by turning on the
mender-grub feature using
MENDER_FEATURES_ENABLE. For instance, in your
MENDER_FEATURES_ENABLE_append = " mender-grub"
If the architecture is x86 or x86-64, and the
mender-full class is inherited, then the
mender-grub feature is already on by default. See the documentation on features for more information.
If using GRUB, Mender by default assumes that the system is using the UEFI boot standard. For systems using BIOS based booting, the
mender-bios feature should also be enabled using
mender-bios feature was introduced in the meta-mender sumo branch, corresponding to the Yocto Project 2.5 sumo release, and is not available in earlier branches.
