= User Guide =
* Connect your laptop to the eithernet port of the Avalon
* Setup your laptop IP address 192.168.0.101
* Open http://192.168.0.100
* Make sure WR703N can access Internet, Configure WiFi:  Network -> WIFI -> Scan(select your WIFI network) -> Join Network -> WPA passphrase -> Submit -> Save & Apply for connect to WIFI Internet
* setup your mining worker: Status -> Cgminer Configuration.
* Restart the cgminer service:  System -> Startup,
* Check your avalon status:  Status -> Cgminer Status
* Setup password/using ssh
ssh root@192.168.0.100 # Once you setup the password the telnet service will be stop. use ssh instead.
 
== Cgminer option ==
'''--avalon-options 115200:24:10:45:282'''. this is the default avalon option. here is the details:
'''115200''': the serial baud. this have to match the controller baud.
'''24''': the miner count.(there are 3 modulars in avalon. each modular have 8 miners), if your avalon have 4 modulars. change it to 32
'''10''': the chip count pre miner.
'''45''': the controller timeout parameter. the valid number: 50, 47, 45, 40.
'''282''': the chip clock. the valid number: 256, 270, 282, 300.
 
== Run cgminer manually ==
In case you need to run Cgminer in linux console please run the following command:
*Restart Cgminer:
# /etc/init.d/cgminer restart
 
If your avalon does not mine properly, please run Cgminer in debug mode with -D --verbose option. For example:
# cgminer -S /dev/ttyUSB0 -o stratum.btcguild.com:3333 -O xxxx:yyyy -D --verbose --avalon-options 115200:24:10:45:282 --api-allow "W:0/0" --api-listen 2>/tmp/cgminer-debug.log
 
== TP-LINK TL-WR703N ==
There is a modify version of TP-LINK TP-WR703N inside Avalon. cgminer running at 703n, this 703n have 64MB ram and modified power supply. it power from the usb-client side(we moved a 0R resistor from '''J1''' to '''R113''' for that)
 
Why there is a ugly USB HUB there?  you can find more information about AR9331's usb stability issue [https://forum.openwrt.org/viewtopic.php?id=39956 here].
 
=== How to reflash ===
# Download latest Avalon [http://downloads.qi-hardware.com/people/xiangfu/avalon/latest/openwrt-ar71xx-generic-tl-wr703n-v1-squashfs-factory.bin image] to your PC.
# Goto:
  System -> Backup / Flash Firmware -> Flash new firmware image (make sure '''Keep settings''' is checked)
# Select the image you just download. then compare the md5 in next page. if everything fine. click '''Proceed'''
 
'''Attention:''' To avoid your WR703N become a brick, during flash your WR703N be careful DO NOT power off avalon, and DO NOT break your network connection. Just wait there till you see OpenWrt login web page again.
 
'''Attention:''' If not essential please do not re-Flash your Avalon. Because not all of WR703N issue could be resolved by reset button. If you want to play WR703N I would like to recommend you order a standalone TP-LINK WR703N from ebay or somewhere for studying purpose.
 
== WIFI or Ethernet Cable ? ==
Avalon shipped with a 9db antenna after connect it to WR703N usually could establish good wireless connection with your WIFI router. But if for some reason you would like to use Ethernet Cable to connect Avalon with your network, please login OpenWrt and configure the LAN port:
Network -> Interfaces -> LAN -> Edit -> Common Configuration -> General Setup
Disable the DHCP on Lan port
 
'''Attention:''' You need to configure it correctly based on your own network enviroment. If anything wrong you might could not access your WR703N any more.
 
== Start to mine ==
To maximize your Avalon miner's performance, it is recommended that you choose pools with the stratum protocol supported. The default mining pool configured in Avalon is ozco.in. To change it login to OpenWrt:
Status -> Cgminer Configuration
Click "Save & Apply" to save your update and restart cgminer immediately
 
Currently the stratum pools that could work stable with Avalon are:
* [http://50btc.com/ 50BTC.com]
* [https://bitcointalk.org/index.php?topic=158105.0 Solo mining with Eloipool]
* [http://bitminter.com BitMinter]
* [http://eligius.st Eligius]
* [https://www.ozcoin.net Ozcoin]
* [http://www.btcguild.com btcguild]
* [http://mining.bitcoin.cz slush's pool]
* [http://www.triplemining.com Triplemining]
 
To get more information about how to configure specific pools, please check their website. If you run multiple Avalons, we recommend that you create a dedicated worker for each of them. This will make it easier to monitor your Avalons through the pool's website and identify possible problems.

== FPGA controller ==
=== V1.0 ~ V1.2 ===
About '''P5''' jumper: close this jumper will supply 5V to the USB-B port. in this system, the controller board power the 703N from the client side. if you connect the controller itself to a PC, you better remove the jumper.
 
=== V1.5 ===
[[File:Avalon fpga controller v1.5.jpg | 320px]] [[File:Avalon fpga controller v1.5 usb hub.jpg | 320px]]
* Remove the '''[http://www3.picturepush.com/photo/a/13207881/1024/Anonymous/avf1.png F1(Fuse)]''' for fix the USB-HUB chip overheat,
# if you are batch2 user and your received Avalon between '''Apr 26 2013 ~ May 31 2013'''
# the FPGA controller is '''1.5'''
# your FPGA contoller board still have '''F1 mounted'''
you need do this by yourself.  removing F1 will not make the usb hub stop working, F1 powers the USB-A1 plug (which is normally unused), more info please checkout [https://github.com/BitSyncom/avalon-ref/issues/5 here]
 
=== V1.51 ===
* Fixed USB-HUB chip overheat, NO NEEDS remove F1 anymore
 
== Update FPGA controller firmware (NOT FINISHED/FULL DOCUMENT YET) ==

== P2Pool Operation with Avalon ==
There is an /avalon branch Forrest committed to the p2pool github repository. Make sure that is checked out.
 
Next, the following option may need to be passed to Avalon's cgminer:
'''--fix-protocol''': Do not redirect to a different getwork protocol (eg. stratum)
 
The current /avalon branch from Forrest is likely now functional. Please test and report your findings to the IRC channel.
 
'''NOTE''': The best performance the small handful of users who got this working have reported is still about 25-30% DOA against P2Pool (versus the usual DOA of 8-15% or so.) So it's close to desired, but be aware that getting things working in this state currently requires command-line skills and the ability to check-out branches from p2pool's git repository. For the moment, your most efficient options are solo-mining with local pool software, or just using one of the online pools.
 
== About [usb 1-1: clear tt 1 (8030) error -71] ==
Not all 703n have this problem. ignore this section if you never meet this error
 
* There is a power issue with the 703N, The 703N is drawing to much power it caused the USB HUB chip on Senseless's FPGA controller to nearly destroy itself. See the destruction [ http://www.mysenselesslife.com/avalon/DSCN5212.JPG here]
 
* In order to fix it you need had to '''power down the WiFi modem by disable it''', use Eithernet instead. The kernel no long report -71 errors. thanks to senseless and others who help on identify the issue.
 
* If your avalon was far away from your router. eithernet cable not fit. you may want try those kind of devices
** TP-LINK TL-PA500(For mainland China) : http://www.tp-link.com.cn/product_adapter_263.html
** TP-LINK TL-PA511 : http://www.tp-link.com/en/products/details/?model=TL-PA511
 
== Others ==
* There is a pair of gloves in Avalon package. please put it on when assembling or carrying.
 
* About the plastic sheets: please '''remove them BEFORE''' mining. we design the case as a part of heatsink, so remove the plastic sheets is a must
 
* About FAN change: '''DO NOT''' change the fans to a low speed model. will cause over heat. '''DO NOT''' install extra fans at the rear "fan socket". will cause PSU over heat and nearly useless for module cooling.
 
* About install extra heat-sinks on each avalon chip: please do not do that. there is a air gap between the die and package top, install a heatsink on chip is useless. and will cause overheating. because  the top PCB copper act as a heatsink too. do not cover them.
 
* About water cooling: yes, do it.

= How to Compile Your Own Firmware for Avalon =
1. First check if you have met the building prerequisites. Checkout this page first [http://wiki.openwrt.org/doc/howto/buildroot.exigence OpenWrt Buildroot – Installation]
 
For example, if your OS is Ubuntu/Debian, install the required packages like this:
sudo apt-get update
sudo apt-get install  gawk flex quilt xsltproc  unzip subversion git-core build-essential libxml-parser-perl libncurses5-dev zlib1g-dev libssl-dev liblua5.1-0-dev
 
2. Now get the source code, prepare the code and build. '''this needs ~6GB'''
wget https://raw.github.com/BitSyncom/avalon-extras/master/scripts/build-avalon-image.sh
chmod +x build-avalon-image.sh
./build-avalon-image.sh --clone #prepare the code and build, '''ONLY NEED ONCE'''
./build-avalon-image.sh
 
3. Update all repos
  ./build-avalon-image.sh --update
 
4. Only rebuild cgminer
./build-avalon-image.sh --cgminer
 
5. Finally you could get the freshly built firmware files under '''avalon/bin/'''
 
== Compile with kernel usbmon ==
* You need apply [https://lists.openwrt.org/pipermail/openwrt-devel/2013-May/020107.html this patch] to your OpenWrt for enable [https://www.kernel.org/doc/Documentation/usb/usbmon.txt usbmon]
* Run '''make menuconfig''' goto  '''Kernel modules''' --> '''USB Support''' enable '''kmod-usb-mon'''

The Avalon Project produces ASIC miners. The project created by 张楠赓[transliteration needed][1][2] and Yifu Guo.[3] [4] The project started in late 2012 with a BitcoinTalk thread.[5]

Avalon project have three different ASIC, named A3256, A3255, A3233, have two type of bitcoin transaction machines. Avalon1 and Avalon2. right now Avalon project people working very hard on third generation machine. named Avalon3. it is 2U size, using the newest 40nm ASIC, (7GHS/chip, 0.7Watt/G).

After one year of Avalon project started, Yifu Guo(Bitsyncom)[6] left Avalon project. The Canaan Creative[7] (founded by ngzhang) have full in charge of the project running from 2014 and EHash.com(The online shop that accept Bitcoin)[8] was part of Canaan Creative.
