SPI Example

a real data:
1st:
work n chip1
{576'hc16801619d8d4242e06e5fab25a54bbe222e8b877848c34beea79cd6528caf7e33cde02a983dab158119ce2a1c9fc4eddac8ce296d0fd9da6e18f645087e051a2d547050e8dc86b1, 64'ha, 32'h1, 32'h1, 32'h1} 
work n chip0
{576'h1bed3ba0a2cb45c1d8f8ef6712146495c44192c07145fd6d974bf4bb8f41371d65c90d1e9cb18a17fa77fe7d13cdfd7b0063910762a5f25c06b168ae087e051a895170504ac1d001, 64'h5, 32'h1, 32'h1, 32'h1}

2nd:
work n+1 chip1
{576'h0, 64'hb, 32'h1, 32'h1, 32'h1}
work n+1 chip0
{576'h0, 64'h6, 32'h1, 32'h1, 32'h1}

3rd:
work n+2 chip1
{576'h0, 64'hc, 32'h1, 32'h1, 32'h1}
work n+2 chip0
{576'h0, 64'h7, 32'h1, 32'h1, 32'h1}

then get nonce 32'h1beebba0 for chip0, 32'hc1698161 for chip1;

Avalon4

Each module carry 40 A3222 ASICs, the module should be working at 1TH/S and using ~680W power.

IIC

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. 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
