**US** BitFury Setup Guide

[cet]

What exactly are the miso errors? I usually get 3-5 of them in my stat.log file, and have seen a single chip stop hashing from time to time. Is it related to voltage mod, or something inherent to the board? Hash rate stays fairly stable.

Also, i ran the RPI's 'sudo shutdown' command to turn off the unit (previously I just powered off the psu), and on restart am unable to ssh to the pi. (I enter user, enter password, then get "server unexpectedly closed network connection" from the putty program). Did my shutdown method alter the ssh file or settings? The bitfury Web guide and bit miner both show normal hashing

miso = master in, slave out.  It doesn't take many of these types of errors before it causes the whole h-board to auto tune down to next to nothing.  The problem is that the error tends to spread from one bad chip to all other chips.  So far I've been lucky and located the correct chip the first try but it's possible that it might take multiple attempts at shutting down different chips to correct the problem.  I don't think this type of error is normally resolved by slowing the clock.  rebooting can solve it for a short while (half hour or so from what I've seen) but it quickly starts happening again.

I suspect that your other problem with logging into the rPI was a timing issue, it takes a little longer for the rPI to respond to login attempts than it does for the rPI to bring up the built in website.

^i could ssh fine until I used the shutdown command rather than a forced power off.

after a shutdown command you will need to recycle the power before it will come back up.

I've power cycled with psu shutoff, and used the stop/start miner a few times, and still no ssh ability. I could redo the sd card but I'd rather avoid the work and downtime, especially when I'm hashing around 32-33ghash average which I'm happy with until I get more heat sink or an 80mm fan that should arrive soon.

Has anyone tried or looked into replacing the 30a voltage converter? I don't have the skill and tools to replace it myself but an uriius whether anyone has done this to enable overclocking past 35ghash reliably. (I could get to 37ghash but errors increased and id see a [random] chip drop to 0 hashing, which I attribute to either the higher heat or strain on the voltage converter/regulator - noncerate was closer to 34.5ghash)

Main reason I want to ssh is to monitor whether all 16 are running, or if my current hash rate is from 15 chips, since that will help guide me as I tweak the resistance (1.165 was the problematic 32-37ghash range, 1.178 is quite stable between 31-34ghash)

I'd suggest a keyboard and monitor to see what's going on.   If ssh somehow got disabled, you can run sudo raspi-config to turn it back on.  Doesn't make sense that a shutdown would disable it where a power-off wouldn't.  Something very odd there...

i just got my shipment today, with the v2 board, there are no cables , do I need anything extra to assemble this.
kind of clueless where to start.

what do i use to power rasp pi

I believe that the motherboard powers the Pi.

Need a PSU with 2 PCI-E connectors to connect to M-board. The RPi plugs into M-board and gets its power from that.

Sorry to state the obvious but check your box very carefully.  You should have two connectors in the box.  If not you'll have to create your own or wait for Dave to ship you some.

Oh wait, that was August ver. 1 M boards.  For ver. 2, I think you just need PCI-e connectors that come with your PSU.

This. Once the hardware is connected up, you need to change the default ip thats on the SD card. You can do this via a linux workstation. (I used ubuntu, using the terminal to move to the directory for my sd card (marked as 3.7gb filesystem, with its name being a long hexstring, and:

sudo sed -i 's/10.10.11.249/192.168.1.249/' etc/network/interfaces
sudo sed -i 's/255.0.0.0/255.255.255.0/' etc/network/interfaces
sudo sed -i 's/10.1.1.1/192.168.1.1/' etc/network/interfaces

and you should be able to throw the card in your system, power it on (turn on PSU), and find the webgui at 192.168.1.249 (you may change if using a different ip range)

thanks, now i plugged in the rasp pi but it's not hanging down like the images i saw.
what do I do when I see"bitfury login"

You need to firmly grasp the rPi and yank it forcefully downward until it matches the photo exactly.  NO... just kidding, don't do that!

But seriously, start at the beginning of this thread and READ!  Dave posted step-by-step instructions.

login: pi
password: raspberry

I believe it then asks what IP you want to use. After you set that IP, on your browser (on another computer) go to that IP to set the pools and such then hit start mining.

when i put in the IP address, it doesn't load the bitfury admin page. Page doesn't load.

check to make sure your gateway is correct: https://asktom.cf/index.php?topic=288109.msg3086163#msg3086163

[mo_mo]

I have the following errors when loading rasp pi

my default gateway is as follows:

then i setup my IP in Pi

then I went to firefox and put in this IP address 192.168.0.180
it doesn't load the bitfury admin page. Need some help please.

You are not getting an IP because there is a mistake in your interfaces file.  

I hope the ctrl-X shown there isn't an actual line in the file.  If it is, delete that line, save the file,  and then reboot.

[mo_mo]

thanks so much finally able to log in to bitfury admin page,
thanks for the help I took out the ctrl-X from the file and I was able to log in
probably when I was editing the file I accidentally put the ctrl-X in there
many thanks

[-Redacted-]

No problem.  Glad to help.
