The TP-LINK WR703N
- 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 firstname.lastname@example.org # Once you setup the password the telnet service will be stop. use ssh instead.
--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
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 here.
How to reflash
- Download latest Avalon image to your PC.
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:
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.
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.
- Remove the 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 here
- Fixed USB-HUB chip overheat, NO NEEDS remove F1 anymore
Update FPGA controller firmware (NOT FINISHED/FULL DOCUMENT YET)
- Update under Avalon 703N: http://downloads.qi-hardware.com/people/xiangfu/avalon/fpga-controller/

P2Pool Operation with Avalon
Doing anything special is no longer required as of commit 11d63ef66 (which is yet unreleased). Since the recent P2Pool hardfork, dead-on-arrival rates of about 6% are normal, close to normal GPU rates (1-2%), so mining is nearly as efficient as solo mining.
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
- 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.
- Check your firmware version by goto Cgminer Status page
- Latest Firmware is here
- The Avalon firmware SDK: here
Please always using the latest testing image for testing.
- New options for Avalon
--avalon-auto Adjust avalon overclock frequency dynamically for best hashrate --avalon-cutoff <arg> Set avalon overheat cut off temperature (default: 60) --avalon-fan <arg> Set fanspeed percentage for avalon, single value or range (default: 20-100) --avalon-freq <arg> Set frequency range for avalon-auto, single value or range --avalon-options <arg> Set avalon options baud:miners:asic:timeout:freq --avalon-temp <arg> Set avalon target temperature (default: 50)
- Update cgminer to 3.2.1, we have the direct USB feature now.
- Add --lowmem by default
- cgminer-monitor: change the schedule from 5mins to 2mins
- cgminer-monitor: switch from Diff1 work to Last Valid Work

[Firmware Version] => 20130419 cgminer-8e8313c luci-28b4ff2 cgminer-openwrt-packages-f2bc5dc
- For fix the cgminer-monitor, please run this command after you reflash
sed -i 's/ $B / "$B" /' /usr/bin/cgminer-monitor
If you "check the Keep settings", you need fill API Allow to "W:127.0.0.1" after reflash, edit it here: "http://AVALON_IP/cgi-bin/luci/admin/status/cgminer/", "DO NOT" left it blank

How to Compile Your Own Firmware for Avalon
1. First check if you have met the building prerequisites. Checkout this page first 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
4. Only rebuild cgminer
5. Finally you could get the freshly built firmware files under avalon/bin/
Compile with kernel usbmon
- You need apply this patch to your OpenWrt for enable usbmon
- Run make menuconfig goto Kernel modules --> USB Support enable kmod-usb-mon
