Adaptive not working (Raspberrypi)

[b4u-mw]

Hello,
I tried to enable adaptive updates for the raspberrypi target by adding "adaptive" to my slots:

[slot.rootfs.0]
device=/dev/mmcblk0p2
type=ext4
bootname=A
adaptive=block-hash-index

The result is that rauc does not start anymore, I get

Failed to initialize context: Failed to load system config (/etc/rauc/system.conf): Invalid key 'adaptive' in group '[slot.rootfs.0]'

I have rauc version 1.14. This feature should be available since 1.8. I have no idea where to look for or how to debug this.

You need to set it in the image.* section in the manifest, not in your system.conf.

Thank you a lot. With the recipe is it just

# allow adaptive updates
RAUC_SLOT_rootfs[fstype] = "ext4"
RAUC_SLOT_rootfs[adaptive] = "block-hash-index"

in my update-bundle.bbappend ?

Edit: yes it is ;-) Just tried it and got my download reduced from 80 mb to a few mb
