 Avenger 96 Board
 ################
 
-The STM32MP157 is a highly integrated multi-market system-on-chip designed to enable secure and space constraint applications within the Internet of Things. Avenger96 board features dual Arm Cortex-A7 cores and an Arm Cortex-M4 core. In addition, an extensive set of interfaces and connectivity peripherals are included to interface to cameras, touch-screen displays an MMC/SD cards. It also fully supports wireless communication, including WLAN and BLE.

 Bulding Zephyr onto Avenger96 board
 *************************************
+OpenHarmony can be hosted on top of variety of kernels. Currently supported kernels (a.k.a. OHOS flavours) are Linux.
 
-Creating uSD card image for the Avenger96 board
-===============================================
+To build OHOS flavour, use the following command syntax:
 
-Steps for building a BSP for ST's development boards is referred here: `<https://wiki.st.com/stm32mpu/index.php/STM32MP1_Distribution_Package>`_.
+.. code-block:: console
+
+   $ TEMPLATECONF=../sources/meta-ohos/flavours/<lower_case_flavour> . ./sources/poky/oe-init-build-env   build-<flavour>-<stm32mp1-avg96>
+
+   $ bitbake <image-name>
+
+MACHINE variable can be set up in conf/local.conf file under build directory or via command line:
+
+Example:
+
+.. code-block:: console
+
+   $ MACHINE=<stm32mp1-avg96> bitbake <image-name>

+OHOS Linux flavour
+******************
+OHOS Linux flavour is based on poky distribution
+
+Supported images : core-image-minimal
+
+Supported machines : stm32mp1-avg96
+
+Example:
+
+.. code-block:: console
 
-Building the BSP for the Avenger96 follows the scheme of the above build process but starts with a different 'repo' manifest file:
+   $ TEMPLATECONF=../sources/meta-ohos/flavours/linux . ./sources/poky/oe-init-build-env build-ohos-linux-stm32mp1-avg96
+   $ bitbake core-image-minimal
 
-* Create the build directory following ST's recommendations at https://wiki.st.com/stm32mpu/wiki/Example_of_directory_structure_for_Packages.
+You can test the image built for the stm32mp1-avg96 target by issuing:
 
-		
-* Enter the working directory and execute the following commands:
-	
 .. code-block:: console
 
-   $ repo init -u https://github.com/dh-electronics/manifest-av96 -b dunfell
-	  
-   $ repo sync
-	  
-   $ source layers/meta-arrow/scripts/init-build-env.sh
-	  
-   $ bitbake av96-weston
+   $ runqemu stm32mp1-avg96 qemuparams="-nographic"
+
+After successful bootup, you should see following:
+
+.. code-block:: console
 
-The last command will build the BSP. The full build will take about 1-2 hours dpending on machine and internet speed and will require around 25GB disk space.
