Ok there is 16  factory overclocked board. I think PSU can't handle that much.
First set speed on all boards to 52
Login to Pi and do command


1 - After that try run with 12 boards for test for 30 min.
2 - If no hash drop, shutdown miner and add 1 more board.
3 - Make test.
Repeat for max board count working stable.

I strongly suggest decrease voltage on all boards. Turn little pot near Pulse inductor on Hboards counterclockwise about a quarter turn or so.

You can probably get a list of clients by browsing to your access point ip address.

did you try 192.168.1.249?

I think the software takes the network address and replaces the last number by 249, so if your network is 192.168.11.x your bitfury will be 192.168.11.249.

mboard is v3.0

Hi! I download the raspberry pi image from the first post https://dl.dropboxusercontent.com/u/43738391/2013-Sep-27_BFSB_GM2.rar and write it to SD. Now how can I connect to Rpi? What is the default IP in this image?

Mboard version ?

Okay I got it working. The only problem I got now is that I can only get bank number 1-11 working. I have 12 plugged in. but only 11 looks to be working.
I’m have a problem running the rig when I have all 16 h boards plugged in. it would just power up and shut off. But when I remove 4 (left with 12) it would power on and I would be able to hash. However it would only hash with 11 boards. i've also notice that after hashing for about 20min or so, some of the h boards stop hashing. only 4 would be hashing still and the rest would stop. why is that?

Any idea on how to fix this problem.

i doubt that its the psu. but i could be wrong. my psu is 700w and 570w towards 12v. i have 2 pci-e cables on the psu.
if you think its the psu. please direct me to the right place to buy the right psu.
psu model:
coolmax
cu700b

Guys I have a question about the H-board.

Where can I download the H-board layout file? I am trying to get one manufactured.

Thanks

 

For anyone who has a V1 BlackArrow Bitfury board - the latest cgminer 3.8.1 (3.8.0 also) has the RPi source for a driver now - consider it an early release since there are certain improvements I'll make to it that I've already sorted out what to do - in future versions - but it already runs with great performance.

The configure option is --enable-bab

It runs at 39.9GH/s valid shares with a bit under 10% HW errors above the 39.9GH/s on a standard board
i.e. if you were to also count bad nonces returned (which I prefer not to but I will mention in case anyone wishes to compare that number) it's returning 44GH/s of good+bad nonces.

I've run it with a single board on Raspbian to write and test it - it's based on the V1 initialisation of a single board.
I based the I/O code on the chainminer GPIO/SPI code as should be obvious for anyone who looks at my driver-bab.c and chainminer (as I also mention that at the top of driver-bab.c)

It's a bit CPU hungry so soon I'll be spending more effort on reducing that - 20% CPU with a single board - I've only tested with a single board.

It also doesn't tune the chip at all - so there is also assured performance improvement there - it runs at default settings at the moment.
That's the next effort I'll expend on the driver.

If anyone has a standard V1 BitFury board I'd also be curious to know if it works with them.

I have a version 2.3 M board.  I updated my Chainminer and now it only detects 2/5 cards.

there is no best.cnf file

and instead of 5x16 = 80 chips, my bitfury shows 88 chips when I know there are only 80 chips.


My question is what do I do now?
