GRUB

This section describes the Yocto configuration needed to integrate with the GRUB bootloader.

Enabling GRUB

If GRUB integration is not already enabled, you can enable it by adding the snippet below to your build configuration. For instance, in your local.conf:

MENDER_FEATURES_ENABLE_append = " mender-grub mender-image-uefi"
MENDER_FEATURES_DISABLE_append = " mender-uboot mender-image-sd"

See the documentation on features for more information.

BIOS based systems

If using GRUB, Mender by default assumes that the system is using the UEFI boot standard. For systems using BIOS based booting, add the mender-bios feature to the Yocto Variable MENDER_FEATURES_ENABLE.
