Avalon4 CGMiner Under Ubuntu 14.04

Download

Inside your home directory, download Cgminer
git clone https://github.com/Canaan-Creative/cgminer

Compile

cd cgminer
git checkout origin/avalon4 -b avalon4
./autogen.sh --enable-avalon4
make -j 4

Run

sudo ./cgminer --avalon4-fan 60 --avalon4-freq 200 --avalon4-voltage 7125 --lowmem -o http://stratum.pool:3333 -u  work -p pass 
or
sudo ./cgminer --avalon4-fan 60 --avalon4-freq 200 --avalon4-voltage 7125 --lowmem  -o http://stratum.pool:3333 -u  work -p pass --api-allow W:192.168.2,W:192.168.2.1 --api-listen $@ 2>./log

Tweak

• Led

 Format: ascset|ASCN,led,modularid
 eg: cgminer-api "ascset|0,led,1"

• Fan

 Format: ascset|ASCN,fan,fanmin[-fanmax]
 eg: cgminer-api "ascset|0,fan,10" or cgminer-api "ascset|0,fan,10-100"

• Voltage

 Format: ascset|ASCN,voltage,MMID-value[-miner_id-val_offset]
 eg: cgminer-api "ascset|0,voltage,1-7750"
     cgminer-api "ascset|0,voltage,1-7750-0-125"

Technical details

• The auc take 1~2ms betwwen write and read. even the polling delay is 0 (4800 means 1ms)
• The cgminer each polling takes ~20ms. even the polling delay is 0ms

MM Notes

mm-tools for Raspberry Pi (Model B)

mm-tools is a program to upgrade Avalon4 mm firmware through Raspberry Pi.

Support mm versions(MM-4.0: >= 401412-7ef4ab10, MM-4.1: Any one)

Ugrade file link: For MM-4.0 For MM-4.1

Method 1:Upgrade it through CLI

In order to use mm-tools, you should use RASPBIAN image on your Raspberry Pi.

• How to use mm-tools

1. Enable iic on Raspberry Pi

a. Commit "blacklist i2c-bcm2708" in raspi-blacklist.conf under /etc/modprobe.d first.
the example of raspi-blacklist.conf:
       # blacklist spi and i2c by default (many users don't need them)
       
       blacklist spi-bcm2708
       #blacklist i2c-bcm2708

b. Add i2c.conf under /etc/modprobe.d.
the example of i2c.conf:
      options i2c_bcm2708 baudrate=400000

c. Load i2c-dev module from start
      echo "i2c-dev" >> /etc/modules

2. Clone & Compile & Run
git clone https://github.com/Canaan-Creative/Avalon-extras.git
cd ./Avalon-extras/mm-tools;make
sudo su
make download && ./mm_tools

Method 2:Upgrade it through LuCI

Use the latest avalon firmware for Raspberry Pi(Model B) openwrt-brcm2708-sdcard-vfat-ext4.img

You can upgrade mm firmware through the page: Status->MM Upgrade

Compile flags

Value	MBOOT	MM41	DEBUG
0	No mboot	Support MM-4.0	Disable debug
1	Support mboot	Support MM-4.1	Enable debug
