+ESP32-S3-EYE
+############
+
+Overview
+********
+
+The ESP32-S3-EYE is a small-sized AI development board produced by [Espressif](https://espressif.com).
+It is based on the [ESP32-S3](https://www.espressif.com/en/products/socs/esp32-s3) SoC.
+It features a 2-Megapixel camera, an LCD display, and a microphone, which are used for image
+recognition and audio processing. ESP32-S3-EYE offers plenty of storage, with an 8 MB Octal PSRAM
+and a 8 MB flash.
+
+Hardware
+********
+
+The ESP32-S3-EYE board consists of two parts: the main board (ESP32-S3-EYE-MB) that integrates the
+ESP32-S3-WROOM-1 module, camera, SD card slot, digital microphone, USB port, and function buttons;
+and the sub board (ESP32-S3-EYE-SUB) that contains an LCD display.
+The main board and sub board are connected through pin headers.

+   * - No.
+     - Key Component
+     - Description
+   * - 1
+     - Camera
+     - The camera OV2640 with 2 million pixels has a 66.5° field of view and a maximum resolution of 1600x1200. You can change the resolution when developing applications.

+     - The LED (green) turns on when USB power is connected to the board. If it is not turned on, it indicates either the USB power is not supplied, or the 5 V to 3.3 V LDO is broken. Software can configure GPIO3 to set different LED statuses (turned on/off, flashing) for different statuses of the board. Note that GPIO3 must be set up in open-drain mode. Pulling GPIO3 up may burn the LED.

+
+Prerequisites
+*************
+
+Espressif HAL requires WiFi and Bluetooth binary blobs in order work. Run the command
+below to retrieve those files.
+
+.. code-block:: console
+
+   west blobs fetch hal_espressif
+
+.. note::
+
+   It is recommended running the command above after :file:`west update`.
+
+Building & Flashing
+*******************
+
+Simple boot
+-----------
+
+The board could be loaded using the single binary image, without 2nd stage bootloader.
+It is the default option when building the application without additional configuration.
+
+.. note::
+
+   Simple boot does not provide any security features nor OTA updates.
+
+MCUboot bootloader
+------------------
+
+User may choose to use MCUboot bootloader instead. In that case the bootloader
+must be built (and flashed) at least once.
+
+There are two options to be used when building an application:
+
+1. Sysbuild
+2. Manual build
+
+.. note::
+
+   User can select the MCUboot bootloader by adding the following line
+   to the board default configuration file.
+
+   .. code:: cfg
+
+      CONFIG_BOOTLOADER_MCUBOOT=y
+
+Sysbuild
+--------
+
+The sysbuild makes possible to build and flash all necessary images needed to
+bootstrap the board with the ESP32 SoC.
+
+To build the sample application using sysbuild use the command:
+
+.. zephyr-app-commands::
+   :tool: west
+   :zephyr-app: samples/hello_world
+   :board: esp32s3_eye/esp32s3/procpu
+   :goals: build
+   :west-args: --sysbuild
+   :compact:
+
+By default, the ESP32 sysbuild creates bootloader (MCUboot) and application
+images. But it can be configured to create other kind of images.
+
+Build directory structure created by sysbuild is different from traditional
+Zephyr build. Output is structured by the domain subdirectories:
+
+.. code-block::
+
+  build/
+  ├── hello_world
+  │   └── zephyr
+  │       ├── zephyr.elf
+  │       └── zephyr.bin
+  ├── mcuboot
+  │    └── zephyr
+  │       ├── zephyr.elf
+  │       └── zephyr.bin
+  └── domains.yaml
+
+.. note::
+
+   With ``--sysbuild`` option the bootloader will be re-build and re-flash
+   every time the pristine build is used.
+
+For more information about the system build please read the :ref:`sysbuild` documentation.
+
+Manual build
+------------
+
+During the development cycle, it is intended to build & flash as quickly possible.
+For that reason, images can be built one at a time using traditional build.
+
+The instructions following are relevant for both manual build and sysbuild.
+The only difference is the structure of the build directory.
+
+.. note::
+
+   Remember that bootloader (MCUboot) needs to be flash at least once.
+
+Build and flash applications as usual (see :ref:`build_an_application` and
+:ref:`application_run` for more details).
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32s3_eye/esp32s3/procpu
+   :goals: build
+
+The usual ``flash`` target will work with the ``esp32s3_eye/esp32s3/procpu`` board
+configuration. Here is an example for the :zephyr:code-sample:`hello_world`
+application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32s3_eye/esp32s3/procpu
+   :goals: flash
+
+Open the serial monitor using the following command:
+
+.. code-block:: shell
+
+   west espressif monitor
+
+After the board has automatically reset and booted, you should see the following
+message in the monitor:
+
+.. code-block:: console
+
+   ***** Booting Zephyr OS vx.x.x-xxx-gxxxxxxxxxxxx *****
+   Hello World! esp32s3_eye/esp32s3/procpu
+
+Debugging
+*********
+
+ESP32-S3 modules require patches to OpenOCD that are not upstreamed yet.
+Espressif maintains their own fork of the project. The custom OpenOCD can be obtained at
+`OpenOCD ESP32`_
+
+The Zephyr SDK uses a bundled version of OpenOCD by default.
+You can overwrite that behavior by adding the
+``-DOPENOCD=<path/to/bin/openocd> -DOPENOCD_DEFAULT_PATH=<path/to/openocd/share/openocd/scripts>``
+parameter when building.
+
+Here is an example for building the :zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32s3_eye/esp32s3/procpu
+   :goals: build flash
+   :gen-args: -DOPENOCD=<path/to/bin/openocd> -DOPENOCD_DEFAULT_PATH=<path/to/openocd/share/openocd/scripts>
+
+You can debug an application in the usual way. Here is an example for the :zephyr:code-sample:`hello_world`
+application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32s3_eye/esp32s3/procpu
+   :goals: debug
