+**Notes**
+Github Discussions (https://github.com/zephyrproject-rtos/zephyr/discussions)
+are available to first verify that the issue is a genuine Zephyr bug and not a
+consequence of Zephyr services misuse.
+
+This issue list is only for bugs in the main Zephyr code base
+(https://github.com/zephyrproject-rtos/zephyr/). If the bug is for a project
+fork (such as NCS) specific feature, please open an issue in the fork project
+instead.
+-->
+
+**Describe the bug**
+<!--
+A clear and concise description of what the bug is.
+
+Please also mention any information which could help others to understand
+the problem you're facing:
+ - What target platform are you using?
+ - What have you tried to diagnose or workaround this issue?
+ - Is this a regression? If yes, have you been able to "git bisect" it to a
+   specific commit?
+ - ...
+-->
+
+**To Reproduce**
+<!--
+Steps to reproduce the behavior:
+1. mkdir build; cd build
+2. cmake -DBOARD=board\_xyz
+3. make
+4. See error
+-->
+
+**Expected behavior**

+**Logs and console output**
+<!--
+If applicable, add console logs or other types of debug information
+e.g Wireshark capture or Logic analyzer capture (upload in zip archive).
+copy-and-paste text and put a code fence (\`\`\`) before and after, to help

+title: ''
+labels: TSC

+

+
+## Origin
+
+Name of project hosting the original open source code
+Provide a link to the source
+
+## Purpose
+
+Brief description of what this software does
+
+## Mode of integration
+
+Describe whether you'd like to integrate this external component in the main tree
+or as a module, and why. If the mode of integration is a module, suggest a
+repository name for the module
+
+## Maintainership
+
+List the person(s) that will be maintaining the integration of this external code
+for the foreseeable future. Please use GitHub IDs to identify them. You can
+choose to identify a single maintainer only or add collaborators as well
+
+## Pull Request
+
+Pull request (if any) with the actual implementation of the integration, be it
+in the main tree or as a module (pointing to your own fork for now). Make sure
+the PR is correctly labeled as "DNM"
+
+## Description
+
+Long description that will help reviewers discuss suitability of the
+component to solve the problem at hand (there may be a better options
+available.)
+
+What is its primary functionality (e.g., SQLLite is a lightweight
+database)?
+
+What problem are you trying to solve? (e.g., a state store is
+required to maintain ...)
+
+Why is this the right component to solve it (e.g., SQLite is small,
+easy to use, and has a very liberal license.)
+
+## Dependencies
+
+What other components does this package depend on?
+
+Will the Zephyr project have a direct dependency on the component, or
+will it be included via an abstraction layer with this component as a
+replaceable implementation?
+
+## Revision
+
+Version or SHA you would like to integrate initially

-      other commercial damages or losses), even if such Contributor
-      has been advised of the possibility of such damages.
-
-   9. Accepting Warranty or Additional Liability. While redistributing
