Issue with ostree commit during Torizon Minimal Image Build: Parsing oe.layers=None Error

oshadha · May 6, 2025, 12:55pm

I’m building a Yocto image for the Verdin iMX8M Plus (Kirkstone) following the guide here: Accelerating Edge AI on Toradex Modules | Hailo Processor.

The base image (torizon-minimal) built successfully. However, after adding the meta-hailo and meta-gstreamer1.0 layers, the build fails during the do_image_ostreecommit task.

The error message is as follows:

How can I resolve this issue? What might be causing the oe.layers=None metadata error?

Thanks in advance.

Hello! Thank you for providing detailed information about your build issue.

The error message:

error: Parsing oe.layers=None : 0:expected value

occurs because Torizon OS (and its Yocto build) expects all custom Yocto layers—including your meta-hailo and meta-gstreamer1.0 layers—to be initialized as Git repositories. The build tries to extract revision metadata from each layer, but fails if the layer is not version-controlled with Git, resulting in oe.layers=None and triggering this error during do_image_ostreecommit.

Solution:
Initialize each custom layer as a Git repository and make an initial commit. You can do this with the following commands for each layer (run these in the root directory of each custom meta-layer):

git init
git add .
git commit -m "Initial Commit" -m "Add <meta-mylayer> from template"

Replace <meta-mylayer> with the actual name of your layer, such as meta-hailo or meta-gstreamer1.0.

Once you have initialized both layers as Git repositories and committed the files, restart your build.
This should resolve the oe.layers=None error during the OSTree commit stage.

You can read more in the Toradex documentation here:

Summary of steps:

For each custom meta-layer directory (e.g., meta-hailo, meta-gstreamer1.0):

cd path/to/meta-hailo
git init
git add .
git commit -m "Initial Commit" -m "Add meta-hailo from template"

cd path/to/meta-gstreamer1.0
git init
git add .
git commit -m "Initial Commit" -m "Add meta-gstreamer1.0 from template"

Re-run your Yocto build.

This is a mandatory requirement for Torizon OS builds to track layer revision information.

Best regards,
Toradex AI Assistant.

Greetings @oshadha,

The additional layers you added, are they managed as git repos? This is required in Torzion OS since the git revision information for every meta-layer is included in the OSTree commit metadata. More information on this here: Custom meta layers, recipes and images in Yocto Project (hello-world examples) | Toradex Developer Center

Jeremias
