Hi Scrypt miners,

I was lucky enough to get one of the first Scrypt ASICs produced by Chinese GridSeed during my stay in South Korea last month. Cheers to Dis Btopia of xbitcoinx.com! Smiley I just hooked up one unit containing 5 chips to my Ubuntu box via USB port and here is what I did to get it running. Mind you, these instructions are for mining Scrypt, not SHA256 or dual mode, which the ASIC can also do. Most of the information I pieced together from this post in Chinese: http://cybtc.com/article-468-1.html

Download GridSeed's modified cpuminer and unpack zip file:
Code:
wget https://github.com/gridseed/cpuminer/archive/master.zip
unzip master.zip
cd cpuminer-master

..or download via git:
Code:
git clone git@github.com:gridseed/cpuminer.git
cd cpuminer

Install automake:
Code:
sudo apt-get install automake

You might need to install other compiling tools. I didn't need to, because I compiled other things before.

Compile:
Code:
./autogen.sh
./configure CFLAGS="-O3"
make

Connect and power up ASIC.

Find correct USB device:
Code:
ls /dev/*USB*

..or watch syslog while plugging in ASIC:
Code:
tail -f /var/log/syslog

Start mining (replace "ttyUSB0" with device found above and add your pool data):
Code:
sudo ./minerd --freq=600 --gc3355=/dev/ttyUSB0 --url=<your pool> --userpass=user:pass

You should now see lots of output with yellow "LTC" lines. If you see red lines, that's bad. Wink Anyway, post here if you run into troubles.

I am not quite sure what the green and red LEDs are about. As far as I can tell there is no English documentation about that anywhere. I assume green (which is on as soon as power and USB are connected) indicates a certain ready state and red (which flashes sometimes) means hardware errors.

I am getting a lot of "Invalid nonce" errors in the cpuminer output along with red LED flashing. Probably because by mistake I got a 12V/0.5A power supply instead of 12V/5A and chips run low on power. So I can't tell you much about hash rates etc. right now. I'll get another power supply next week, so stay tuned.

Any updates to this?  I will be receiving my first Gridseed 5 chip model tomorrow and would like to run it from my raspberry pi.  Just curious if you have any other tips to add, or if you have had any problems running the miner this way.  Thanks for posting above hopefully that will help me when I try to set this up tomorrow.

Do the 5 chips devices not have switches for mode?

Are you asking If it will work or saying that it doesn't?

The package manager line for apt-get would have to be changed to use yum/rpm.  aside from that I don't see an issue.

on paper yes miavitor - but in reality it's just one challenge after another so I gave up in installed 'ew'buntu and it's running.

of course now my challenge is to get a bank of two of these gridseeds working.

since they'll be on a bank I'm not sure that the configuration issues will be to get them all working together....


do I have twenty instances of minerd running one for each gridseed?

sudo ./minerd --freq=600 --gc3355=/dev/ttyUSB0 --url=<your pool> --userpass=user:pass

sorry for the elementary question but I have 20 of these on the way and need to know exactly what type of USM cables I need to hook these up the the hubs I've ordered.

thanks in advance.

i think you will find everything you need to know (and much more!) in miaviator's complete guide: https://bitcointalk.org/index.php?topic=494625.0

@miaviator excellent guide by the way! respect.

i didn't follow up on mining with gridseed by the way, because a few other things distracted me recently. Wink my single gc3355 is now sitting in a box doing nothing. :-/

Is this plug and play?

 I mean do I only have to plug these littles beasts with a USB cable to a USB hub connected to my PC and Ubuntu will recognize them off the bat?

Thanks for your replies.

what do you mean by psu tweaking. I'll probably try to dual mine since the bitcoin is free money vs power used.

I'm going to go with 1200W psu for each 10 gridseeds and I'd hate to underpower them.
