-How to get the binary image
----------------------------
-
-Configure with the default configuration:
-
-.. code-block:: sh
-
- make ARCH=arm a9m2440_defconfig
-
-Build the binary image:
-
-.. code-block:: sh
-
- make ARCH=arm CROSS_COMPILE=armv4compiler
-
-**NOTE:** replace the armv4compiler with your ARM v4 cross compiler.
