+
+Overview
+********
+MikroE Quail for STM32 is a development board containing an `STM32F427`_
+microcontroller. It is equipped with four mikroBUS sockets.
+The edges of the board are lined with screw terminals and USB ports for
+additional connectivity.
+
+Hardware
+********
+The Quail board contains the following connections:
+
+  - Four mikroBUS connectors
+  - 32 screw terminals
+  - two USB ports, one for programming and one for external storage
+
+Furthermore the board contains three LEDs that are connected
+to the microcontroller.
+
+Supported Features
+==================
+
+.. zephyr:board-supported-hw::
+
+Connections and IOs
+===================
+
+The four mikroBUS interfaces are aliased in the device tree so that their
+peripherals can be accessed using ``mikrobus_N_INTERFACE`` so e.g. the SPI on
+bus 2 can be found by the alias ``mikrobus_2_spi``. The numbering corresponds
+with the marking on the board.
+
+For connections on the edge connectors, please refer to `Quail for STM32 User Manual`_.
+
+Programming and Debugging
+*************************
+
+.. zephyr:board-supported-runners::
+
+Applications for the ``mikroe_quail`` board can be built and flashed in the usual way
+(see :ref:`build_an_application` and :ref:`application_run` for more details).
+
+
+Flashing
+========
+The board ships with a locked flash, and will fail with the message:
+
+.. code-block:: console
+
+   Error: stm32x device protected
+
+Unlocking with OpenOCD makes it possible to flash.
+
+.. code-block:: console
+
+   $ openocd -f /usr/share/openocd/scripts/interface/stlink-v2.cfg \
+       -f /usr/share/openocd/scripts/target/stm32f4x.cfg -c init\
+       -c "reset halt" -c "stm32f4x unlock 0" -c "reset run" -c shutdown
+
+Here is an example for the :zephyr:code-sample:`hello_world` application.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/hello_world
+   :board: mikroe_quail
+   :goals: build flash
+
+You should see the following message on the console:
+
+.. code-block:: console
+
+   Hello World! mikroe_quail
+
+
+Debugging
+=========
+
+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: mikroe_quail
