Hard to say (at least for me), norulezapply, since you're using a rather "uncommon" platform to mine (raspberry).

Anyway, in my experience, the only difference is in the controller FPGA firmware, 1.3 seems better in achieving an uniform U: across all boards (but you already have it).

Here are mine

-snip-

As you can see I've got a U: around 2.30-2.60, I'm using cgminer 2.4.3 as well on an ubuntu low power pc.

Note that I have a FPGA which is underperforming the others (it is ICA 9 here) and which has always underperformed no matter what controller revision I was using.

I'm starting cgminer like this

spiccioli.

I've had similar problems attempting to run it with the built-in 4232.  Could possibly be related to the undocumented DIP switch functions.  If enterpoint would only publish a schematic, or even a .ucf for their board, we could happily have native support in no time.

Yohan: Please release a pinout or ucf file for your board, I will happily write the java interface.

Can you not see the obvious ( and famous ) 4-6 weeks line ?

Looks more like 4-6 years for real BFL product shots.

first let me say I take anything that comes out of the *** camp w/ this much salt.

that being said, assuming they can deliver on even 20% of what they've promised, have you come up with/are thinking about anything similar to help the Enterpoint camp stay competitive?

Id rather they just focus on their bitstream or even release an early version that can hash at 300+, Ive tried for hours to get the twin, or 190_v3 working and it just wont do it on my board. I did get it working again with the shipping_test bitstream so at least I'm getting 110 hash.

Yes I think all of this is currently possible and I will double check that this morning that I am not talking crap in any shape or form. We use these processes on our lines already. The load of the 4 array SPI Flash does take over 30 minutes so it does need patience to do. We do a 5-10 boards together here to stop it becoming a line blocker.

I will also see if we can somehow streamline the instructions.

I would be happy to give enterpoint an interest free loan if they could beat BFl to it.

Who's with me?

In most cases when it will not work is the frequency/noise problem. See my post here -> https://bitcointalk.org/index.php?topic=78239.msg992167#msg992167

I use the programming switches for the shipping bitstream. But i got it also work with the switch settings for the twin_test.bit.



I use:
Original Icarus bitstream "190M_V3.bit"
MPBM latest git with some changes on Win7 32bit
Worker setting in MPBM 115200 baud, jobinterval 11.34

Standard unit switch settings:
SW1 1234 on
SW6 1 off, 234 on
SW2 1234 on
SW3 2 off, 134 on
SW4 2 off, 134 on
SW5 1234 on

Programming switch settings:
SW1 3 off, 124 on
SW6 1234 on
SW2 - SW5 same as Standard

I can programm only in the temporary mode, if i turn off the unit then it have the shipping bitstream again.

I hope this helps a bit

1 - BFL delivers on their promise

A little story.
I ordered BitForce Single September 21, 2011 (pre-order number 22) and received only in April 17, 2012. Wait time 209 days.
When do we receive our ASICs? What do you think?

Ageism?!  lmfaooooo that is a new one to me.

And not trolling (not intending to anyways).  I am serious.  If I am investing thousands of dollars in hardware, I DAMN SURE do not want Father Times daughter working on it.

Yohan, is it technically possible for you to start ASIC deveopment? We trust you and we can deposit lots of money for your kickstarter.

Its not too late now, i really hope you should start ASIC project now.

Can anyone that has a problem email the new support email with the following:

Board serial number

What revision you think the controller is in. If you didn't touch it just say that.

A description of the problem you have.

What OS your host is running.

What your host is, if you know processor etc. that is all useful to know.

We will try and understand or even try and replicate the problems so that they can debugged. We probably won't do much on that until early next week so please be patient. The better bitstream is our priority for the next few days and as a lot of this stuff will change , hopefully for the better, once that is in place.
We don't want to put a lot of time on the "get going" unless that is strictly necessary as it will delay the better stuff. It would be far better for us to move the whole of the software and firmware side forward so that's the effort for the next few days.

I would also like to know who has a unit working ok is with the currently limited bitstreams. This might get us some insight to where problems actually are as much as the problem unit data. I suspect we don't have a major issue and it's all about recognising any weaknesses in combinations of different things and make even as simple as better docs.

Well their statement "We have come up with a way to ship without invoking import taxes for our customers" is a complete and utter lie and rubbish.

The Single cost a total of £90 ($140) import tax.

@ norulezapply       Well I define "Begging" as asking for something for nothing for MY own fianical benifit.

If you think thats what I was after then your missing the spirit of the whole post. I was using it as A LEARNING TOOL and nothing else.

I thought it was a novel way to learn how to work with bitcoins before I actually dived into this area

I plan on setting up a mining rig when I can establish whats safe to spend my money on, as at the moment there are competing technoligies arriving ( FPGA vs ASIC ). I dont have the luxury of spending 2000 quid for a rig that MIGHT last 9 to 12 months before its obselete, while I mine say half a bitcoin a day!

We are starting a Cairnsmore1 specific support email address where we can route problems to the best engineer to be able to sort them out. We will also start a FAQ page in the next few days and try and cover common problems there so hopefully whatever you encounter that there is an answer already waiting for most of you. The support email is bitcoin.support AT enterpoint.co.uk.
