+CUBIEBOARD7
+===========
+
+About this
+----------
+
+This document describes build and flash steps for Actions S700 SoC based Cubieboard7
+board.
+
+Cubieboard7 initial configuration
+---------------------------------
+
+Default Cubieboard7 comes with pre-installed Android where U-Boot is configured with
+a bootdelay of 0, entering a prompt by pressing keys does not seem to work.
+
+Though, one can enter ADFU mode and flash debian image(from host machine) where
+getting into u-boot prompt is easy.
+
+Enter ADFU Mode
+----------------
+
+Before write the firmware, let the development board entering the ADFU mode: insert
+one end of the USB cable to the PC, press and hold the ADFU button, and then connect
+the other end of the USB cable to the Mini USB port of the development board, release
+the ADFU button, after connecting it will enter the ADFU mode.
+
+Check whether entered ADFU Mode
+--------------------------------
+
+The user needs to run the following command on the PC side to check if the ADFU
+device is detected. ID realted to "Actions Semiconductor Co., Ltd" means that
+the PC side has been correctly detected ADFU device, the development board
+also enter into the ADFU mode.

+ Firmware upgrade successfully!
+
+Debian image can be downloaded from here[1].
+
+Once debian image is flashed, one can get into u-boot prompt by pressing any key and from
+there run ums command(make sure, usb cable is connected between host and target):
+
+.. code-block:: none
+
+ owl> ums 0 mmc 1
+
+Above command would mount debian image partition on host machine.
+
+Building U-BOOT proper image
+----------------------------
+
+.. code-block:: none
+
+ $ make clean
+ $ export CROSS_COMPILE=aarch64-linux-gnu-
+ $ make ARCH=arm cubieboard7_defconfig
+ $ make u-boot-dtb.img -j16
+
+u-boot-dtb.img can now be flashed to debian image partition mounted on host machine.
+
+.. code-block:: none
+
+ $ sudo dd if=u-boot-dtb.img of=/dev/sdb bs=1024 seek=3072
