**US** BitFury Setup Guide

[zurg]

Guys I received my Aug full kit a few days ago and have been troubleshooting it ever since. It was DOA out of the box due to networking issues (the Gateway IP was set to something like 10.10.2.1). After that was corrected it wouldn't respond on the web server port for some reason. I bought a new router and set it up on it's own isolated network and hooked the raspberry pi directly up to a keyboard and monitor to get that resolved.

The unit has been hashing for two days now but having stability issues. On power up everything starts out at full speed but then it loses hash rate over time. I have optimized the cards by putting the highest rate cards in the first few slots and the worst performing cards at the end. One card stopped hashing completely and was removed.

My board stop hashing about 2 days or so.  All chips show up as 0.000 in my stat logs and will remain in that state for a long long time (if not indefinitely).  So the only thing I do now is power cycle the whole unit.  It seems to recover afterwards for another 2.x days

I personally use /30 - restarting the proxies every ten minutes seems a little excessive.

I learned today that I have to Stop and Start miner to get it functioning properly.
Restarting proxy didn't do much. 
There is definitely an issue with the units loosing hashrate over time.

You could always modify that cron job to run sudo /opt/bitfury/start-miner.sh once every couple of hours instead, or in addition.   That would kill the currently running miner process and restart it.

I'd like to ask for your help with a problem i am having with my bitfury full kit.

I have worker1 set for the 16h board unit; worker2 set for the 2h board unit.
Everything's been working great (with the occasional restart) since day one.

A few hours ago the hash rate of worker2 started decreasing from 45 down to 8. restart fixed it for a while before the hash rate started dropping to 0 again. After the second or third restart, the unit now doesn't respond at all (putty/browser), there's no activity on the ethernet link, only the red led on the rpi is lit.

A few minutes ago, the exact same thing happened to worker1!

Has anyone else had this issue? If so, what's the cause and what can i do to fix it?

Thank you.

Power off the PSU, then back on - sounds like something crashed on the RPi .  The lack of SSH connectivity and no activity on the Ethernet points that way...

I don't think the RPi crashes.  I think there seriously is something wrong with the chips or the way the chips communicate to one another.  Sometimes the hashrate of all chips drop to 0.000.  Other times they are really really low... and other times, they work fine.  It's quite unpredictable.


EDIT:
Ok, so my hashrates dropped big time again.  Checked stat.log and noticed that autotune must have turned off my I flag for all chips.  I'm going to try disabling autotune for all chips this time.

Hi -Redacted-,

By restart i meant i powered the units off, left them off for a while, then powered them back on again.
I've just discovered that the red led means the rpi is getting power, but no green light means the sd card is unreadable.

I tried to back up the card tonight with the instructions you gave back in post #23, but win32diskimager failed with an error after 1% of the card had been read. I believe if i had done this when i received the kit, i wouldn't be on here now asking for help!

Can someone upload the sd card image for me, the one that shipped with the kit?  Thank you.

Dave has made download copies available of the images.  See near the bottom of the OP.  You may end up needing to reformat the SD card before you can successfully write the image.

the biggest problem I saw with autotune was that when a chip was generating MISO errors the errors propagated to all of the other chips on the m-board.  Once I located that single chip and turned it off then auto tune worked great. All of my boards are hashing at or above 25gh/s.

Thank you for that link to the rpi img file.
Now i just need to wait a few more hours for it to download over my "high-speed" internet connection...

Has anyone mined via wireless instead of ethernet cable?  How difficult would it be to set up?

I have some dlink adapters. I'd really like to be able to have the wifi option too.

Both of my rigs are being fed via a 5 port switch attached to a TP-Link WR700N. ~$30 from Newegg. Run it in 'client' mode and it acts as a wifi bridge.

The rPI has a very old ARM11 cpu which is being taxed already by the stratum proxy process. It would be best to delegate wifi using an external device.

Well, rebooted my Pi today and

Does that mean reload the SD card?


Whats the proper way to reload the card?

Yes, your sd card has read errors. You might even want to get a new sd card.
Which image to use depends on your M-board: https://bitcointalk.org/index.php?topic=288109.0

Thanks.
Ugh, this is just great, lol
Good thing I downloaded the image a few days ago.
Bad thing... I didn't bring my laptop today to have the fun switching IP range from 192.168.1.x to 192.168.254.x
my HDMI cable is like 1ft, lol but at least I have an HDMI monitor here at work.
Microcenter doesn't open until 10am (never understood that)
I got no Linux machines at work. , although I did find Win32DiskImager and reflashing the image as I type.

Get an HDMI to DVI connector/adapter and you can use nearly any modern monitor.  Get a additional DVI to VGA connector and you can use any monitor - they usually bundle this last one with graphics cards....

Ok, I think my SD card is messed up now.
I reloaded the image and booted Pi up, a bunch of errors etc.

Now it's asking me for root password for maintenance

Did you reformat the card before writing the image to it?

Ugh, no, I assumed that writing an image would take care of that.
Retrying...
