Does anyone know if a driver exists that can do this. The one based on chainminer (driver-bab.c) for Cgminer, Seems to be Raspberry pi only. The Beaglebone looks better suited for controlling 20+ boards due to it's faster CPU. If I match the SPI pins from the controller to the beaglebone, I think just a proper driver might do it. Maybe? Edit: Been trying to get this to work. No go, I am simply not a programmer. I will offer .25BTC to who ever modifies the driver to work. Or posts information in this thread that leads to a working setup. The information would have to be very specific to Blackarrow bitfury boards working with a Beaglebone black. I can provide detailed info on my configuration. I have CGminer 4.3.4 compiled in minepeon for Beaglebone black. The bab driver and bfsc (BFL singles) are added. I have a V2 controller and 20 cards. I followed instructions here: http://elinux.org/BeagleBone_Black_Enable_SPIDEV to enable the SPI01 interface. I also mapped the pins from the Beaglebone to the cable connecting the the V2 controller card. Used these diagrams: Raspberry Pi http://www.raspberrypi-spy.co.uk/2012/06/simple-guide-to-the-rpi-gpio-header-and-pins/ BeagleBone http://elinux.org/Beagleboard:Cape_Expansion_Headers |

Is anyone else having trouble with Eligius and disconnects using LRP? I have been having a time with this. I am now using another pool and all is working great. Eligius and P2Pool just won't work with LRP. There appears to be some hard-coded buffer size in LRP that drops the end off the work requests, which is why it works for a bit (at the start of a block) and then suddenly starts failing. I've had a ticket open about this since before it was sold. That's why I don't use LRP any more for AusMiner. Just the answer I was looking for. Thanks. I guess my Ants aren't rentable until this is patched.  Is this issue ever going to be patched? Thanks. |

Can the cubieboard2 or cubietruck be used as the host instead of a pi?
My thinking on this is no. But I am no coder. I have been trying to get these to work on a BeagleBone black with no luck. I think the driver in cgminer (driver-bab.c) is written only for the spi interface on the pi. Kano did a lot of work on this driver, maybe he can add support for non raspberry pi devices. When I run CGminer compiled with this driver it states that it cannot access the SPI interface. As far as the original chainminer, I have no idea.  |

Well since these did not come with the outer 4-pin connector, I improvised! I soldered 14 gauge wire directly to the tinned side of the board, then linked to other two pins to the next board. Limited the chain to 5 boards. Then I installed high current automotive type spade connectors on the first board in the chain. These connected to terminals on a modified 750 watt Dell XPS power supply. Each power supply has 10 boards attached to it using 4 14 gauge wires. All the wires are cold and I get ~12V at the board connector. 17 boards Use about 700W supplied with 240V and hash at 678Gh. Almost 1W per Gh!  |

I am not onsite where my boards are. Does anyone know the length of the brass bars included with these? I guess about 20-24mm.

There are only two ways the cable can be plugged in...right? I'm certain that every board I plugged up had the same color wire on the side facing the number one pin. Are the boards labeled incorrectly? It won't do me any good to order a stack of controllers if they just burn up every time I hook a board up.

Check for shorts on your boards between ground (corner rings) and pin 10 on SPI connector. |

I will post a picture next time I take it down for maintenance. But basically I soldered a SMD cap between pin 10 (1.8V) and the ground ring next to it. Did this on two
SPI connectors. This reduced the ripple measured considerably.

Hi, Figured I would post my findings with one of the 17 board "kits" in this thread. First off, it took me about a week of tinkering to get these things humming at 40Gh per board with all 17 connected to one pi/controller. My reject/error rate is below 1%. First thing you need to do to get rid of the rejects/dupes/error is OVERCLOCK your Pi to 900mhz. The little Raspberry pi can't handle more than about 12 of these boards if you use Cgminer. Next thing to do is edit the file driver-bab.c before you compile. Edit line 2124 from: #define BAB_STD_WORK_DELAY_uS 900000 to: #define BAB_STD_WORK_DELAY_uS 800000 Increasing the SPI bus from 96000 to about 165000 helped with the waiting for work messages. That is line 42. This plus overclocking made CGminer run perfect with the 17 board kit. Also for you electronic types, installing some tantalum caps on the 1.8V regulator helped a lot with SPI errors. Grounding between the boards and controller is VERY important! Hope this helps those who have these boards and are struggling with error/dupes/rejects. Edit: Don't use the barrel connector/PCI express adapters that came with the kit. Make your own out of 14 gauge or better wire. I had one catch on fire!  Estimate that each board requires about 50W. Safety first. |

running cgminer 4.3.3 and compiling with --enable-bab i get BaB0: Delay getting work reply ...
chips are detected at startup and connected to pool, can any cgminer users help?
I always had better luck with bfgminer than with cgminer. Over time I have switched both of my rigs back to chainminer, which I did not want to do. How did you get BFGminer to recognize Blackarrow bitfury boards? I never have been able to. I am running minepeon. |

Hi, Having a small problem with Cgminer 4.3.3 and Blackarrow bitfury boards. Every so often I get a (duplicate) share that is indeed a dupe of a share just before it. I changed line 529 from #define BAB_WORK_EXPIRE_mS 7800 to 5800. This seems to have helped. Any suggestions? Thanks! Edit: My pool is Eligius. Edit#2: Line 529 seems to have minimal effect on "dupes".  No one has any ideas? |

If I purchased a kit (I did) from Minersource, can I buy more boards at the $40 price point? Also, do these boards have a tendency
to produce many errors when connected in larger numbers. I can get sub 1% out of EACH board separately, using Cgminer, but
more that 10 connected at once gives me crazy errors. Even if I knock the speed down to 50! I would like to connect 24 boards
to one R-pi/controller.
Thanks!
We do see a tendency for a smaller number of errors, but not significantly. You may have a bad board in the stack that is effecting the others. You can buy as many of the boards @ $40 as you would like. I have tested each board separately and logged errors. All of them where below 3%. When I connect 10 boards to the controller the errors stay low. However when I connect 15, errrors are almost always above 5%. I noticed increasing the SPI frequency from 96000 to 500000 helped.

Have you overclocked ? i want to know how or a guide to that also i would love to buy 18 boards from this group buy i want to know if i will get the r-pi and the controller if i did No overclocking, but as long as you buy > 13 boards, pi and controller are included. |

I get that too. Very little documentation on that. |

Would you accept escrow with a hero member? Would you ship to east coast US?
Thanks!

All of my Ants are operating at 300Mhz and using about 200-220W at the wall. I like only needing one CX750M for two ants!
is this without hardware modification? what Avg speed u got @ 300Mhz This is achieved by "pencil modding" one of the feedback resistors and indicated in the beginning of this thread. I modded them from 4.7K to about 3.3K. This produced much lower power usage with acceptable errors (<2%). They average about 153Gh. Temps are MUCH more manageable now too.  |

just want to add, wifi has been fine for me.
good as you are the rare wi fi winner… so did you a) add an antenna b) use 1 ant or many ants c) have you run wif fi for 5 days with no issues. d) have you clocked the hash preformance e) what is your wifi router make and model? f) is the router far or pretty close g) do you live near military bases and or airports. I'm also one of the wifi winners! A) yes, an antenna on every unit. B) Many ants in two locations C) Yes, I have to restart a unit every 10 days or so. D) Yes, OCd units to 400mhz. Units hash between 194-204Gh/s E) Site 1: Asus rt-n16 with dd-wrt. Site 2: Asus AC68u w/stock firmware. F) Site 1: 10m Site 2: 18m G) Site 1: No. Site 2: Yes, ~4km thanks for the info. lastly what antenna do you use? TP-Link TL-ANT2408C. However, I changed out the SMA connectors on the S1's to Male. I'm not sure if people realize they're female and most antennaes are female as well. I have had good luck with the antennas out of laptops (in the lid). Already has the right connector on it and is small. Also most of them have adhesive and can be "stuck" to the endplate. Course I have hundreds of them from my work. An example: http://www.ebay.com/itm/Universal-Internal-Antenna-for-Wireless-Mini-PCI-PCI-E-Laptop-Desktop-Computer-/260668842387That bag has two in it! |
