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.

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

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
 eg: cgminer-api "ascset|0,voltage,1-7750"

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

NEXT-TESTING

NOTICE: Only for testing
TL-WR703N wifi display none

Issues

WIFI cann't work on TL-WR703N

This issue was caused by ubus, We can enable or disable it through the button in  the webpage, 
but the display is invalid when wifi was opened.
Work around method: https://github.com/openwrt/luci/commit/ecb0c2f11b861e5035b0397d2396ee4b5e9b3c3e

Local hashrate count lower than pool or actual.
