-**Notes (delete this)**
-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**
-A clear and concise description of what you expected to happen.
-
-**Impact**
-What impact does this issue have on your progress (e.g., annoyance, showstopper)
-
-**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
-explain the issue. (if unable to obtain text log, add a screenshot)
-
-**Environment (please complete the following information):**
- - OS: (e.g. Linux, MacOS, Windows)
- - Toolchain (e.g Zephyr SDK, ...)
- - Commit SHA or Version used
-
-**Additional context**
-Add any other context that could be relevant to your issue, such as pin setting,

-# Background
-
-The [TSC Project Roles] defines the main roles for the Zephyr Project, including
-Maintainer, Collaborator, and Contributor.
-
-By default anyone that contributes code or documentation is a Contributor, but
-with the lowest [GitHub Permission Level] of Read. For example, Contributors
-with Read permission do not have the permission to add reviewers to a pull
-request.
-
-Use this template to nominate a GitHub user for the Contributor role with
-Triage permission level, which allows the user to add reviewers to a pull
-request and be added as a reviewer by other users.
-
-# Nomination
-
-## GitHub User
-
-Provide the following information about the GitHub user:
-
-1. Full Name
-1. GitHub username
-1. Organization (optional)
-
-## Supporting Documents
-
-Add links to 3-5 GitHub pull requests, in the Zephyr project, authored or
-reviewed by the GitHub user that demonstrate the user's dedication to the
-Zephyr project.
