+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,

+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      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
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+         ```
+
+   3. 编译镜像
+
+      a) 生成bootloader.bin
+
+         ```shell
+         $ cd esp-idf
+         $ ./install.sh
+         $ ./export.sh
+         $ cd examples/get-started/hello_world
+         $ make menuconfig
+         (关掉 Partition Table -> [*] Generate an MD5 checksum for the partition table 选项)
+         $ make bootloader
+         ```
+
+      b) 生成分区表
+
+         使用`gen_esp32part.py`脚本将用户自定义csv文件转换为对应bin文件，如：
+         ```shell
+         $ gen_esp32part.py partitions_user.csv partitions_user.bin --disable-md5sum
+         ```
+
+         esp32 csv文件可参考以下配置：
+
+         ```
+         nvs,data,nvs,0x9000,24K,
+         phy_init,data,phy,0xf000,4K,
+         factory,app,factory,0x10000,1M,
+         ```
+
+## 2.获取源码
+
+[代码获取](https://gitee.com/openharmony/docs/blob/master/zh-cn/device-dev/get-code/sourcecode-acquire.md)
+
+提示: 可以使用 `repo` 命令来获取源码。
+
+## 3.源码构建
+
+   1. 执行hb set命令并选择项目`esp32_wrover_ie_demo`。
+
+   2. 执行hb clean && hb build命令构建产生 `OHOS_Image` 的可执行文件。
+
+      ```shell
+      $ hb set
+      $ hb clean && hb build
+      ```
+
+   3. 在构建完成之后，对应的可执行文件在主目录下：
+
+      ```
+      out/esp32_devkitc_v4/esp32_wrover_ie_demo/
+      ```
+
+   4. 在主目录下执行以下命令生成bin文件：
+
+      ```shell
+      esptool.py --chip esp32 elf2image --flash_mode dio --flash_freq 80m     \
+       --flash_size 4MB -o out/esp32_devkitc_v4/esp32_wrover_ie_demo/OHOS_Image.bin out/esp32_devkitc_v4/esp32_wrover_ie_demo/OHOS_Image
+      ```
+
+## 4.在开发板中运行镜像
+
+   1. 下载烧录工具
+
+      烧录工具链接：https://www.espressif.com/sites/default/files/tools/flash_download_tool_v3.8.8.zip
+
+   2. 使用烧录工具
+
+      使用参考 https://docs.ai-thinker.com/esp_download 中 “不支持OTA” 的FLASH地址配置方式：
+
+      a) 配置bootloader.bin在地址0x1000，配置partition-table.bin在地址0x8000，配置OHOS_Image.bin在地址0x10000。
+
+      b) 配置SPI SPEED为40MHz，配置SPI MODE为DOUT，配置FLASH SIZE为8Mbit，波特率设置为115200。
+
+      c) 点击START开始下载。
+
+注1：如果没有手动生成bootloader.bin和分区表，可以直接使用vendor/esp/esp32/image下的bootloader.bin和分区表。
+
+注2：烧录用的bin文件需要按照4-4中的方法使用esptool.py工具生成。
