+# FEX scripts

+Board configuration scripts can be found here: <https://github.com/linux-sunxi/sunxi-boards/blob/master/sys_config>. You can compile them with the "fex2bin" tool found here: <https://github.com/linux-sunxi/sunxi-tools>.
+
+To use, copy the compiled FEX to your MS-DOS partition, load it with U-Boot, and then tell the kernel where to find it with the "sysconfig=" boot option. For example, uEnv.txt on a Cubieboard2 might look like this:
+
+[[!template  id=programlisting text="""
