Hi Siva,

Thanks for the new version.

It looks like we still have a failing selftest:

2026-06-02 20:22:55,502 - oe-selftest - INFO - 
fitimage.KernelFitImageRecipeTests.test_fit_image_sign_initramfs_bundle 
(subunit.RemotedTestCase)
2026-06-02 20:22:55,503 - oe-selftest - INFO -  ... FAIL
...
Initialising tasks...ERROR: 4014 unbuildable tasks were found.
These are usually caused by circular dependencies and any circular dependency 
chains found will be printed below. Increase the debug level to see a list of 
unbuildable tasks.

Identifying dependency loops (this may take a short while)...

Can you have a look at the issue?
The configuration used to reproduce can be found in the "OE Selftest:
Add layers" and "OE Selftest: Write config" steps.

Thanks,
Mathieu
