-## Checklist
-
-_This entire section can be deleted if all items are checked._
-
-* [ ] Enough information to help reviewers understand the issue, its root cause, impact, and the proposed solution
-* [ ] Enough information to help reviewers understand the feature, its functional description, example, documentation, test cases, test results, feature TODO list
-* [ ] The MR Title describes the change, including the component name, ie "lwip: Add support for IP over Pigeon"
-* [ ] All related links, including JIRA, backport, submodule MR, are mentioned in the `Related` subsection.
-* [ ] Any GitHub issues are linked inside the git commit message and corresponding release notes
-* [ ] Add label for the area this MR is part of
-* [ ] For documentation updates, check if label `Docs` and `needs translation:CN` or `needs translation:EN`  have been added when the other language version still needs the update. Skip adding the label if the document is not yet translated.
-* [ ] Check if documents requiring translation fall under get-started section. If yes, add the labels mentioned above. Then the documentation team will assign a translator for you. Please inform the translator to prepare translation once your MR is ready to merge. The translation should be included in your MR to get it merged. For more information, see documentation workflow in Wiki.
-* [ ] Any necessary "needs backport" labels are added
-* [ ] Check if this is a breaking change. If it is, add notes to the `Breaking change notes` subsection below
-* [ ] Release note entry if this is a new public feature, or a fix for an issue introduced in the previous release.
-* [ ] The commit log is clean and ready to merge.
-* [ ] All relevant CI jobs have been run, i.e. jobs which cover the code changed by the MR.
-* [ ] Pipeline with Python 3 has been successfully run, i.e. `@bot ...; with Python3`, if the MR adds or changes Python code.

-
-_For issues, put enough information here to help reviewers understand the issue, its root cause, impact, and the proposed solution._
-
-_If this issue is a regression, specify in the `Related` subsection below, in which commit or MR it was introduced. This helps reviewers to check if the backport labels are set correctly._
-
----
-
-_For features, put enough information here to help reviewers understand the feature, its functional description, example, documentation, test cases, test results, feature TODO list._
-
----
-
-_For other small/non-public changes, which are not expected to be in the release notes, can be mentioned here, include:_
-
- * changes that don't apply to customers, e.g. some CI fixes, test only MR and etc
-
-## Related
-
-* Mention or related JIRA tasks (e.g. IDF-0000), to make sure they get updated.
-* Mention submodule MR, if there is
-* Mention backport(ed) MR, if there is
-
-_Don't touch the subsection titles below, they will be parsed by scripts._
-
-## Release notes (Mandatory)
-
-_Changes made in this MR that should go into the **Release Notes** should be listed here. Please use **past tense** and *specify the area (see maintainers page of IDF internal wiki)*. If there is a subscope, include it and separate with slash (`/`). Minor changes can go to the descriptions above without a release notes entry._
-
-_Write all the changes in a **list** (Start at the beginning of the line with `-` or `*`). If multiple changes are made, each of them should take a single line. If there is only one change to list, it should still be the only line of a list. If this MR does not need any release notes, write "No release notes" here without the `-` or `*`. e.g._
-
-* [WiFi] Changed/fixed/updated xxx
-* [WiFi] Added support of xxx
-* [Peripheral Drivers/I2S] Fixed xxx (https://github.com/espressif/esp-idf/issues/xxxx)
-
-## Breaking change notes
-
-_Remove this subsection if not used._
-
-_If there are any breaking changes, please mention it here. Talking about (1) what is not accepted any more, (2) the alternative solution and (3) the benefits/reason. e.g._
-
-_Please strictly follow the breaking change restriction, which means, if there is a breaking change but you are merging to non-major versions, you have to separate the breaking part out to another MR for a major version. The breaking change subsection is only accepted in MRs merging to major versions._
-
-* [VFS/UART] Now vfs_uart_set_rts_cts accept one more instance argument, to support configuration to different ports.

-                Select the way the application is built.
-
-                By default, the application is built as a binary file in a format compatible with
-                the ESP-IDF bootloader. In addition to this application, 2nd stage bootloader is
-                also built. Application and bootloader binaries can be written into flash and
-                loaded/executed from there.
-
-                Another option, useful for only very small and limited applications, is to only link
-                the .elf file of the application, such that it can be loaded directly into RAM over
-                JTAG. Note that since IRAM and DRAM sizes are very limited, it is not possible to
-                build any complex application this way. However for kinds of testing and debugging,
-                this option may provide faster iterations, since the application does not need to be
-                written into flash.
-                Note that at the moment, ESP-IDF does not contain all the startup code required to
-                initialize the CPUs and ROM memory (data/bss). Therefore it is necessary to execute
-                a bit of ROM code prior to executing the application. A gdbinit file may look as follows (for ESP32):
-
-                    # Connect to a running instance of OpenOCD
-                    target remote :3333

-### 非 GitHub 分叉的 ESP-IDF 项目
-
-ESP-IDF 中的子模块采用相对路径（[详见 .gitmodules 文件](.gitmodules)），所以它们会指向 GitHub。
-如果 ESP-IDF 被分叉到的仓库不在 GitHub 上，那么你需要在克隆结束后运行该[脚本](tools/set-submodules-to-github.sh)。它会为所有的子模块设置绝对路径，接着可以通过 `git submodule update --init --recursive` 完成子模块的更新。
-如果 ESP-IDF 是从 GitHub 上克隆得到，则不需要此步骤。
-
-## 寻找项目
-
-除了入门指南中提到的 [esp-idf 模板项目](https://github.com/espressif/esp-idf-template)，ESP-IDF 的 [examples](examples) 目录下还带有很多其它示例项目。
-
-一旦找到了需要的项目，便可以进入该目录，执行配置和构建操作。
-
-如果要基于示例工程开始你自己的项目，请将示例工程复制到 ESP-IDF 目录之外。
-
-# 快速参考
-
-详细的使用方法请参考上面入门指南的链接，这里仅仅列举一些 ESP-IDF 项目开发中常用的命令：
-
-## 设置构建环境
-
-（请参考入门指南中列出的详细步骤。）
-* 在主机中安装入门指南中提到的构建所依赖的工具。
-* 将 ESP-IDF 中的 `tools/` 目录加入 PATH 环境变量中。
-* 运行 `python -m pip install -r requirements.txt` 安装 Python 依赖库。
-
-## 配置项目
-
-`idf.py menuconfig`
-
-* 打开项目的文本配置菜单。
-* 使用上下键浏览菜单。
-* 使用回车键进入子菜单，退出键返回上一级菜单或者退出配置。

-
-## 编译项目
-
-`idf.py build`
-
-编译应用程序，引导程序，并根据配置生成分区表。
-
-## 烧写项目
-
-当构建结束，终端会打印出一条命令行，告知如何使用 esptool.py 工具烧写项目到芯片中。但是你还可以运行下面这条命令来自动烧写：
-
-`idf.py -p PORT flash`
-
-将其中的 PORT 替换为系统中实际串口的名字（比如 Windows 下的 `COM3`，Linux 下的 `/dev/ttyUSB0`，或者 MacOS 下的 `/dev/cu.usbserial-X`。如果省略 `-p` 选项，`idf.py flash` 会尝试使用第一个可用的串口进行烧写。
-
-这会烧写整个项目（包括应用程序，引导程序和分区表）到芯片中，此外还可以使用 `idf.py menuconfig` 来调整串口烧写相关的配置。
-
-你也不必先运行 `idf.py build`，再运行 `idf.py flash`，`idf.py flash` 会根据需要自动重新构建项目。
-
-## 观察串口输入
-
-`idf.py monitor` 会调用 [idf_monitor 工具](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html)来显示 ESP32 和 ESP32-S2 的串口输出。`idf_monitor` 还包含一系列的功能来解析程序崩溃后的输出结果并与设备进行交互。更多详细内容，请参阅[文档](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/idf-monitor.html).
-
-输入 `Ctrl-]` 可退出监视器。
-
-想要一次性执行构建，烧写和监视，可以运行如下命令：
-
-`idf.py flash monitor`
-
-## 仅编译并烧写应用程序
-
-在第一次烧写过后，你可能只想构建并烧写你的应用程序，不包括引导程序和分区表：
-
-* `idf.py app` - 仅构建应用程序。
-* `idf.py app-flash` - 仅烧写应用程序。
-
-`idf.py app-flash` 会自动判断是否有源文件发生了改变而后重新构建应用程序。
-
-（在正常的开发中，即使引导程序和分区表没有发生变化，每次都重新烧写它们并不会带来什么危害。）
-
-## 擦除 Flash
-
-`idf.py flash` 并不会擦除 Flash 上所有的内容，但是有时候我们需要设备恢复到完全擦除的状态，尤其是分区表发生了变化或者 OTA 应用升级。要擦除整块 Flash 请运行 `idf.py erase_flash`。
-
-这条命令还可以和其余命令整合在一起，`idf.py -p PORT erase_flash flash` 会擦除一切然后重新烧写新的应用程序，引导程序和分区表。

-有关 ESP-IDF 的最新支持政策，详见 [支持期限政策](https://github.com/espressif/esp-idf/blob/master/SUPPORT_POLICY_CN.md)
-
-支持期限政策
-=====================
-
-ESP-IDF 的每个主要版本和次要版本（如 V4.1、V4.2 等）自其首次稳定版本发布之日起将支持 30 个月。
-
-支持意味着 ESP-IDF 团队将会对 GitHub 上的发布分支继续进行 bug 修复、安全修补等，并根据需求定期发布新的 bugfix 版本。
-
-支持周期包括“服务周期“和“维护周期”：
-
-| 周期      | 期限     | 是否建议新项目使用？         |
-| -------     | ------------ | ------------------------------------- |
-| 服务周期     | 12 个月    | 是                                   |
-| 维护周期 | 18 个月    | 否                                    |
-
-在版本的服务周期内，bug 修复版本会较为频繁发布。某些情况下，版本在其服务周期内可能会增加对新功能的支持（这仅适用于需要达到新产品特定规管标准或要求的功能，并且引入新问题的风险极低。）
-
-在版本的维护周期内，版本仍然会继续支持，但仅会对严重问题或安全问题进行 bug 修复。
-
-建议在开始新项目的时候使用处于服务周期的版本。 
-
-在某一版本支持期限结束，停止更新维护 (EOL) 前，建议用户升级所有项目至较新的 ESP-IDF 版本。根据《支持期限政策》，我们将停止对 EOL 版本进行 bug 修复。
-
-《支持期限政策》不适用于预发布版本（包括 beta、preview、-rc 和 -dev 版本等）。有时，在发布的版本中存在被标记为 "Preview" 的特定功能，则该功能也不在支持期限内。
-
-有关 [ESP-IDF 不同版本](https://docs.espressif.com/projects/esp-idf/zh_CN/latest/esp32/versions.html)（主要版本、次要版本、bugfix 版本等）信息，可参阅《ESP-IDF 编程指南》。
-
-示例
--------
-
-ESP-IDF V3.3 于 2019 年 9 月发布，将支持 30 个月至 2022 年 2 月停止。
-
-- V3.3 的首个发布版本为 2019 年 9 月发布的 v3.3。
-- ESP-IDF 团队将持续进行 bug 修复、安全修补等更新，并 backport 至分支 release/v3.3。
-- 定期从 release 分支创建稳定的 bugfix 版本，比如，v3.3.1、v3.3.2 等，并建议用户保持使用最新的 bugfix 版本。
-- V3.3 的 bugfix 版本发布将持续至 2022 年 2 月，届时所有 V3.3.x 将停止更新维护。
-
-现有版本
------------------
-
-ESP-IDF V4.1 及所有后续更新版本都将遵守该《支持期限政策》。每一版本发布时将同时公布其支持期限。
-
-对于该政策公布之日前发布的版本，应适用下述支持期限：
-
-* ESP-IDF V4.0.x 将支持至 2021 年 10 月。
-* ESP-IDF V3.3.x 将支持至 2022 年 2 月。
-* ESP-IDF V3.1.x 和 V3.2.x 都将在 2020 年 10 月停止支持。
-* ESP-IDF v3.1.x 之前的版本已经停止支持。
-  
-政策历史
---------------
-
-* 2019 年 9 月。该政策将 ESP-IDF 版本发布分为标准支持版本和长期支持版本。 
-* 2020 年 7 月。从现在开始，所有发布的版本都将有相同的支持周期，等同于之前的长期支持周期。新增了”服务周期“，期间版本的更新将较为频繁。
