I really like the design guys.  Great job AM!

[daddyfatsax]

I have gotta board that will not hash at all. I have double checked all the connections and still cannot get it to power up.

[helipotte]

What do some of the "ASIC section" variables do?  Anyone?

Like these:  WakeUp period(s)    Normal/Smart 0/1

Is the fan supposed to run at 100% all of the time?

So, a report on pool compatibility issues. I haven't tested bfgminer yet, but ckpool proxy has been working perfectly on ozcoin for a while. ckolivas looked at the issues I was seeing between his proxy and brickpools pools apparently based off Luke-Jr software? He looked it over and looked it over and threw up his hands in disgust after a couple hours. It appears the things are basically hard-coded to ghash.io nonstandard header format, which means that, basically, if ghash changed their header structure these things wouldn't mine on a single pool natively. Which is pretty retarded.

Anyway, ckolivas gave us some ideas but had to get back to working on other stuff so we're gonna try and isolate the format issues and fork a slush's proxy implementation to make these stupid things work with any pool. If we can do it (Novak's already got one working on ozcoin, but that's the easy fix) we should be able to release a Windows build for people to use which will make it quite a bit easier for lazy and/or underteched people to not be stuck with ghash.

If this whole thing becomes moot and ASICMiner releases a firmware update to make them not kick stratum testicles in an aggressively impolite manner, I'll be both shocked and pleased. But in the (probably likely) chance they don't, hopefully we'll make an efficient workable solution anyway.

I have two of these connecting to Eligius through Bfgminer.  It works, but not set and forget.  Have to restart the controller/Bfgminer from time to time.  I am using

an old version (3.10) because the newest version (4.70) was even less stable. Bfgminer is running in Windows.

Canary, sidehack, FC or anyone else that has successfully got one of these up...Help Please

Have it together with power to all 8 connections. Power to controller.
3 white cables going from 1st board left connector to 2nd board left connector.
2nd cable going from 2nd board right connector to 3rd board left connector.
3rd cable going from 3rd board right connector to 4th board left connector.
Controller going to board 1 right connector.
I did the megaflash but not sure it updated all the boards. The controller will drop network about every 20 secs or so with all the 3 lights flashing on and off and the network connection light will go off and it drops.
Managed to work in between drops and changed network info to my actual network. When I log in between the drops the status page only shows one board.
Entered ghash just to test and unit isn't hashing.

Is there a special way to hook up cables as well as controller cable? Was I suppose to do something with dip switches I left as they were.

Here is a pic of my main screen in between network drops:

[sidehack]

Set each board's DIP switches to a unique value. What could be happening is every board is addressed the same, so when the controller polls the boards it's getting collisions like mad and errors into a reset. The easiest thing with 4 boards on one controller is flip a different switch on each board.

Thanks, I figured it would be something simple I was missing. By the way after putting that thing together will all the screws I decided you must have the patience of Jobe. I don't know how you did 30 of those without going crazy. If you expand your hosting in near future drop me a pm I would be interested.

Thanks again for the quick answer.

I've actually only assembled 19 of the 31 so far, been also busy running new circuits and troubleshooting the pool compatibility stuff. I'll start the rest tonight and finish up tomorrow though. Saturday will be a much-needed day off, I think I've worked every day so far this month.

By the way slush set up a isolated ip for me to point one at so they could capture the errors to see if it is something easy they can fix on their end. I asked them to leave it up till Friday afternoon so I could get one put together and point there. If I have still problems tomorrow I will pm you with it if you think you would have time to point one at it.

Thanks again.

[sidehack]

Cool. I wonder if slush would want to talk to the guy I've got working on it? We've got a slush proxy modified to truncate the extranonce2 length to pool-requested size, but haven't yet determined what issues there are with non-slush pool compatibility.

I sent you a pm with the email they sent me with the ticket number etc. Feel free to pass it on to him.

How to run on pools other than ghash.io and btcguild with Raspberry PI and bfgminer

    1.Modify /etc/apt/sources.list on your Raspberry PI

    deb http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib
    deb-src http://mirrors.ustc.edu.cn/raspbian/raspbian/ wheezy main non-free contrib

    2.Update the aptitude package on your Raspberry PI

    sudo apt-get update

    3.Download bfgminer

    wget http://luke.dashjr.org/programs/bitcoin/files/bfgminer/4.7.0/bfgminer-4.7.0.zip

    4.Uncompress

    unzip bfgminer-4.7.0.zip

    5.Install dependencies

    sudo apt-get install autoconf libtool libncurses-dev yasm curl libcurl4-openssl-dev libjansson-dev pkg-config libudev-dev uthash-dev libusb-dev libevent-dev

    6.Enter bfgminer directory

    cd bfgminer-4.7.0

    7.Run configuration

    ./configure

    8.Compile bfgminer

    make

    9.Run bfgminer

    ./bfgminer  -o stratum+tcp://stratum.f2pool.com:3333 -u <workername> -p 123 --stratum-port <port(3333 by default)> --set-device PXY:diff=<difficulty(16 or above recommended)>

    10.Set static IP for Raspberry PI(modifying /etc/network/interfaces)
    Take the IP address 192.168.0.100 as an example. Replace iface eth0 inet dhcp as:

    iface eth0 inet static
    address 192.168.0.100
    netmask 255.255.255.0
    gateway 192.168.0.1    

    netmask and gateway are decided by your Raspberry PI's local network settings.

    11.Configure ethernet controllers

    Same example as above. Modify the pool address on ethernet controller to 192.168.0.100 with port 3333.

Actually, I recommend you using Arch Linux for RPi.

It would be much easier to configure:

1. pacman -Syu
2. pacman -S bfgminer
3. and then, you can run bfgminer with your specified parameters.

Has anyone experience this? Suddenly Board 3 started showing 100% error rates:

[Blazed]

The more I read of these the more I am thinking I should not have bought one    Has anyone had a fully working miner yet with out issues?

[sidehack]

I'm seeing 7 of 7 good controllers and about 72 of 76 good boards so far.

Alright that is a pretty bad failure ratio, but maybe I will be lucky!  Mine shipped late so I will not find out until Tuesday

Gotta bad board as well. Hopefully Canary can send me a replacement. Sent an email to the address Friedcat provided, no answer yet.

Ordered and built 4. Up and running without issues on ghash.

But why on GHash.IO? We should support the network and do anything we can to make sure the pools have an equal amount of hashrate. Please consider mining on another pool
