+Elecrow ESP Terminal
+####################
+
+Overview
+********
+
+The Elecrow ESP Terminal is a display device built on the ESP32S3-WROOM 1 N16R8. This board integrates complete Wi-Fi
+and Bluetooth Low Energy functions. For more information, check `Elecrow ESP Terminal`_
+
+Hardware
+********
+
+ESP32-S3 is a low-power MCU-based system on a chip (SoC) with integrated 2.4 GHz Wi-Fi
+and Bluetooth® Low Energy (Bluetooth LE). It consists of high-performance dual-core microprocessor
+(Xtensa® 32-bit LX7), a low power coprocessor, a Wi-Fi baseband, a Bluetooth LE baseband,
+RF module, and numerous peripherals.
+
+Elecrow ESP Terminal includes the following features:
+
+- Dual core 32-bit Xtensa Microprocessor (Tensilica LX7), running up to 240MHz
+- Additional vector instructions support for AI acceleration
+- 512KB of SRAM
+- 384KB of ROM
+- Wi-Fi 802.11b/g/n
+- Bluetooth LE 5.0 with long-range support and up to 2Mbps data rate
+
+Digital interfaces:
+
+- OV2640 camera on I2C0 + GPIOs
+- microSD on SPI2
+- 480x320 RGB666 display with ILI9488 on SPI2
+- Buzzer on GPIO (passive)
+- I2S MEMS microphone on SPIM3
+- 2x external GPIOs with 5V level shifters
+
+Analog interfaces:
+
+- 2x external analog inputs (shared with USB-JTAG/serial D+/D-)
+
+
+Additional information from ESP32 HAL
+#####################################
+
+
+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
+*******************
+
+ESP-IDF bootloader
+==================
+
+The board is using the ESP-IDF bootloader as the default 2nd stage bootloader.
+It is build as a subproject at each application build. No further attention
+is expected from the user.
+
+MCUboot bootloader
+==================
+
+User may choose to use MCUboot bootloader instead. In that case the bootloader
+must be build (and flash) 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.
+   ```
+   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
+   :app: samples/hello_world
+   :board: elecrow_esp_terminal
+   :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 build 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: elecrow_esp_terminal
+   :goals: build
+
+The usual ``flash`` target will work with the ``elecrow_esp_terminal`` board
+configuration. Here is an example for the :ref:`hello_world`
+application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: elecrow_esp_terminal
+   :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! elecrow_esp_terminal
+
+Debugging
+*********
+
+ESP32-S3 support on OpenOCD is available upstream as of version 0.12.0.
+Download and install OpenOCD from `OpenOCD`_.
+
+ESP32-S3 has a built-in JTAG circuitry and can be debugged without any additional chip. Only an USB cable connected to the D+/D- pins is necessary.
+
+Further documentation can be obtained from the SoC vendor in `JTAG debugging
+for ESP32-S3`_.
+
+Here is an example for building the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: elecrow_esp_terminal
+   :goals: build flash
+
+You can debug an application in the usual way. Here is an example for the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: elecrow_esp_terminal
+   :goals: debug
