The Canaan AvalonMiner 721 is hardware blockchain securing hardware technology built using Open Source software. The latest hardware AvalonMiner 721 contains 72 customized ASIC processors named Canaan A3212 which are harmonized together and then across potentially thousands of other AvalonMiners, to do SHA-256 hashing calculations.From the software toolchain all the way to OpenWrt used in Canaan's AvalonMiner Controller, this presentation describes the entire process from start to finish how the software is built, developed, launched and maintained. Of specific interest are the contributions by Canaan back to the Open Source community, including to CGMiner, OpenWRT and other projects.

25. 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.

26. How to generate the firmware - OpenWrt
Automatically
wget https://raw.githubusercontent.com/Canaan-Creative/Avalon-extras/master/scripts/build-avalon-
image.sh -O ./build-avalon-image.sh

27. 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
make -C firmware/auc

28. 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
