Blockchain Software for Hardware: The Canaan AvalonMiner Open Source Embedded System

473 views

Published on

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.

  24. 24. 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.
  25. 25.

  26. 26. 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
  27. 27. 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 More details: https://github.com/Canaan-Creative/MM#how-to-build
