Physical Distinction between 4.0 and 4.1 machine

LED Board

*‘Ver. 4.X’ is marked in the bottom right-hand corner of the lights panel.

 

PMU

 The other way is open the case to check PMU (Power Module Unit)
* (On the left) Three 270uf 16V and two 820uf 16V blue solid capacitors are used in 4.0 version.
* (On the right) Four 100uf 16V and four 560uf 6.3V purple solid capacitors are used in 4.1 version.

 

Controller

* The hardware is the same in 4.0 and 4.1, the only different is the firmware

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

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.
