+********
+
+ESP32-DEVKITC-WROOM is a series of low cost, low power system on a chip microcontrollers
+with integrated Wi-Fi & dual-mode Bluetooth.  The ESP32 series employs a
+Tensilica Xtensa LX6 microprocessor in both dual-core and single-core
+variations.  ESP32-WROOM is created and developed by Espressif Systems, a
+Shanghai-based Chinese company, and is manufactured by TSMC using their 40nm
+process. [1]_
+
+The features include the following:
+
+- Dual core Xtensa microprocessor (LX6), running at 160 or 240MHz
+- 520KB of SRAM

+- Bluetooth v4.2 BR/EDR and BLE
+- Various peripherals:
+
+  - 12-bit ADC with up to 18 channels
+  - 2x 8-bit DACs
+  - 10x touch sensors
+  - Temperature sensor
+  - 4x SPI
+  - 2x I2S
+  - 2x I2C
+  - 3x UART

+
+System requirements
+===================
+
+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
+-------------------
+
+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: esp32_devkitc_wroom
+   :goals: build
+
+The usual ``flash`` target will work with the ``esp32_devkitc_wroom`` board
+configuration. Here is an example for the :ref:`hello_world`
+application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32_devkitc_wroom
+   :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! esp32_devkitc_wroom
+
+Debugging
+---------
+
+ESP32-DEVKITC-WROOM support on OpenOCD is available upstream as of version 0.12.0.
+Download and install OpenOCD from `OpenOCD`_.
+
+On the ESP-WROOM-32 DevKitC board, the JTAG pins are not run to a
+standard connector (e.g. ARM 20-pin) and need to be manually connected
+to the external programmer (e.g. a Flyswatter2):
+
++------------+-----------+
+| ESP32 pin  | JTAG pin  |
++============+===========+
+| 3V3        | VTRef     |
++------------+-----------+
+| EN         | nTRST     |
++------------+-----------+
+| IO14       | TMS       |
++------------+-----------+
+| IO12       | TDI       |
++------------+-----------+
+| GND        | GND       |
++------------+-----------+
+| IO13       | TCK       |
++------------+-----------+
+| IO15       | TDO       |
++------------+-----------+
+
+Further documentation can be obtained from the SoC vendor in `JTAG debugging
+for ESP32`_.
+
+Here is an example for building the :ref:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: esp32_devkitc_wroom
+   :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: esp32_devkitc_wroom
+   :goals: debug
+
+Note on Debugging with GDB Stub
+===============================
+
+GDB stub is enabled on ESP32.
+
+* When adding breakpoints, please use hardware breakpoints with command
+  ``hbreak``. Command ``break`` uses software breakpoints which requires
+  modifying memory content to insert break/trap instructions.
+  This does not work as the code is on flash which cannot be randomly
+  accessed for modification.
