How to generate the firmware - OpenWrt
Step by step
1. Clone OpenWrt source code
git clone git://github.com/openwrt/openwrt.git openwrt
cd openwrt && git checkout 851a8906
2. Add new feeds
src-git luci https://github.com/Canaan-Creative/luci.git;cgminer-webui-avalon7
src-git cgminer git://github.com/Canaan-Creative/cgminer-openwrt-packages.git
3. Choose the target and compile, that is it.

How to generate the firmware - AUC
Step by step
1. SDK: Install LPCXpresso 6 or above (Free Edition)
2. Clone source code
git clone https://github.com/Canaan-Creative/Avalon-USB-converter.git Avalon-USB-
converter
3. Change to Avalon-USB-converter and compile.
cd Avalon-USB-converter

How to generate the firmware - MM
Step by step
First you need install the ISE for sure. then edit the isedir under xilinx.mk by default we are
using /home/Xilinx/14.6/ISE_DS/
$ make -C firmware/toolchain # Install the lm32-rtems-4.11- toolchain under /opt
$ make -C firmware # Generate the final bitstream file .bit/.mcs under firmware/
$ make -C firmware load # Load the config bit file to FPAG by using Xilix Platform cable
