The USB on the AR9331 has bugs. If you want use serial console, please use the direct serial console on 703N (the /dev/ttyATH0). It's far more stable than USB-serial converter. You may want add a USB hub between machine and 703n

• The default firmware IP address is 192.168.0.100, you can access it by http://192.168.0.100
• You may need update the address/DNS to your local configuration. DO NOT FORGET your IP address.
• If the Raspberry Pi can access internet, cgminer should automatic start

• 8GB Memory card: http://item.jd.com/632744.html
• Reflash: sudo dd if=openwrt-brcm2708-sdcard-vfat-ext4.img of=/dev/sdb bs=4M #/dev/sdb is your memory card
• USB Hub, UNITEK Y-2132 USB2.0 13ports
• USB WiFi, EDUP EP-N8508GS

Avalon 2 units communicate with a UART, usually attached to your host via a generic USB UART adapter. First, figure out what COM port (or /dev/ttyUSB on Linux) and run BFGMiner with:

bfgminer -S avalonmm:\\.\COM22 --set avalonmm:clock=1500 --set avalonmm:voltage=1 --set avalonmm:fan=80

• Chip Freq: 1700, Voltage: 10750 --> 119GHs

Extra cooling is recommended, GJPMiningco recommends removing the slide panel that covers the heatsink and adding some fans that blow down into the heatsink - at least 3 fans evenly spaced along the heatsink.

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install libcurl4-openssl-dev pkg-config libtool libncurses5-dev libudev-dev screen xterm
sudo apt-get install git-core
sudo apt-get install openssh-server byobu
sudo apt-get install autoconf
sudo apt-get install automake

Inside your home directory, download Cgminer
sudo git clone https://github.com/ckolivas/cgminer

cd cgminer
sudo ./autogen.sh --enable-avalon2
sudo make -j 4

-
sudo ./cgminer -S /dev/ttyUSB0 --avalon2-freq 500 --avalon2-voltage 7250 --avalon2-fan 50 -o http://stratum.pool:3333 -u  work -p pass 
or
sudo ./cgminer -S /dev/ttyUSB0 --avalon2-freq 500 --avalon2-voltage 7250 --avalon2-fan 50 -o http://stratum.pool:3333 -u  work -p pass --api-allow W:192.168.2,W:192.168.2.1 --api-listen $@ 2>./log

If you use cgminer 4.5.0, the command will like this:

sudo ./cgminer --avalon2-freq 500 --avalon2-voltage 7250 --avalon2-fan 50 -o http://stratum.pool:3333 -u  work -p pass 
or
sudo ./cgminer --avalon2-freq 500 --avalon2-voltage 7250 --avalon2-fan 50 -o http://stratum.pool:3333 -u  work -p pass --api-allow W:192.168.2,W:192.168.2.1 --api-listen $@ 2>./log
