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 include 40 A3222 ASICs, the mdoule should be working at 1TH/S and using 700W power.

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"
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
