Attempting to Integrate

[MichaelBMiner]

Hello,

I am following your README and I have added rauc to my image. When I go to build I get the error
ERROR: Layer rauc is not compatible with the core layer which only supports these series: hardknott (layer is compatible with langdale)

I am using Yocto from NXP and my distro is hardknott. Can anyone explain what is happening here?

Hi @MichaelBMiner,

this is a standard mechanism of Yocto to explicitly maintain the compatibility of different layers.
It is more or less a statement that the layer has been developed for a specific Yocto(/poky) release. The release name is 'hardknott' in your case. For a more detailed explanation see:

https://docs.yoctoproject.org/ref-manual/variables.html#term-LAYERSERIES_COMPAT

When having a 'hardknott' BSP (which is EOL since April 2021 btw!), standard practice is to use the corresponding 'hardknott' branch of all other layers (if available). Thus simply git checkout the hardknott branch of meta-rauc and the error should disappear.

That did work, it gives me a new issue that only appears after adding DISTRO_FEATURES
Please ensure that your setting of VIRTUAL-RUNTIME_init_manager (systemd) matches the entries enabled in DISTRO_FEATURES

[ejoerns]

The manual only suggests to enable rauc in DISTRO_FEATURES. I don't see how this changes init manager.

You can use bitbake <recipename> -e | less to dump and inspect the environment for how DISTRO_FEATURES are set.

Getting closer. I have a customised image so I added the following to my local.conf

DISTRO_FEATURES += "rauc"
CORE_IMAGE_EXTRA_INSTALL += "rauc"
INIT_MANAGER = "systemd"

It cannot seem to find my rauc version. I have added the recipe rauc in recipes core. I have rauc_%.bbappends added as well.

Thank you for the support. I think I almost have it. My image fails on the rootfs step and gives a long output
