1.3 is tested by me.

Controller 1.2 or 1.3 ?

Oh boy, here we go again. Could the documentation get any more confusing ? I mean you post a controller but no bitstream to go with it, why ?

Nice Makomk!

The 150MH/s is also working =) Thanks!

EDIT: To fast again... 150 one have some invalids. Let's wait a bit how it goes

OK, ebereon seems to reckon this works so let's give it a go. http://www.makomk.com/~aidan/makomk_icarus_cm1_20120726.zip contains two Icarus-style bitstreams clocked at 140 MHz and 150MHz that should run on all the FPGAs of the Cairnsmore1, effectively turning it into a pair of slightly slow (280 Mhash/sec each) Icarus-like boards that you can use on your existing miners. The 150 MHz one's untested so I'd recommend starting with the 140 MHz bitstream. 560 MHash/sec per Cairnsmore1's certainly not all that bad.

You want the normal (non-Glasswalker2-alpha) controller for this. Set SW1 and SW6 according to the "Twin Build (Icarus)" diagram on http://www.enterpoint.co.uk/cairnsmore/cairnsmore1_support_materials.html and SW2/3/4/5 according to the "Initial Shipping Build (low performance) diagram. Load firmware, start your mining software and cross your fingers.

Source code is... ahahahahah. It's included as required by the license, but unfortunately a lot of undocumented manual fiddling is required to get from there to the bitstreams.

Yohan - What about the bitstream that goes along with the controller update?

Ok what I should have said, or done, is that dip switches have changed a little again. Programming mode is still available but you need to set a dip switch to enable it. This because we are using all 4 ports now as com ports so the function needs to be changed over to use programming modes.

If you happen to be using an external programming cable there is now an automatic clock shutdown whilst the JTAG chain is running. It's not 100% perfect yet and you can still force clock shutdown using SWITCH3.

Here is the info.

OK, this may sound like a very strange question, but what precisely is connected to pin A4 of the four XC6SLX150s? Particularly on FPGA2/3?

Do not flash the glasswalker controller version befor you have flashed the new bitstream (still not available)

You will lost the Jtag chain and you can't flash with the VM anymore!

You can't flash back the controller version to rev. 1.3!

God thanks i have a jtag cable, with that i was able to flash back rev. 1.3

Yohan, do you plan to support updating the controller from Linux? If not, I'd like to know ASAP: I believe the CM1 will not be profitable without a controller update so I might as well sell my boards now if I can't update them myself.

Waiting for the bitstream itself, it makes no sence without it...

Where do we get the bitstream itself? or are you posting it later? I see the controller, but no bitstream in the zip.

Thanks,

Doff

Cairnsmore controller for Glasswalker2 build is noe available on http://www.enterpoint.co.uk/cairnsmore/cairnsmore1_support_materials.html. This is only for the Glasswalker build and won't work with any other bitstream. Currently only properly supporting 3 FPGAs with 4th running very poorly. Expect a U of about 7.5 from what we have seen and power usage less than 30W.

Im part of a discussion that started with someone singing the praises and merit of a comparison thats not based in reality.

I do apologize for quoting the minimum delivery time of 50 days for a BFL product when the average is 72.
No-one is right all the time, its only when checked by our peers that we continue to learn and grow.
I consider you and all others I converse with part of that process, thanks!


Not at all, its a fair comparison, the people who ordered in may got product in july.  I agree its better to pre-order and only have to pay when its ready to ship, but that does not create a time dilation in any way.


Toughen up princess ...

kind regards

OK this is ridiculous. You are distorting the truth unnecessarily. In fact, the wait time was far less than any other competitor, period. Furthermore, no payment was accepted until the units were ready to ship.

No shit, sherlock. The same goes for ngzhang, ztex, and everyone else except BFL, who refuse to allow their devices to be used for other purposes.

Actually, the current average wait time for BFL deliveries is 72.343 days, not 50. AND, you have your funds tied up the entire time, doing nothing!
You are also providing conflicting statements and views.
Really, wildemagic, you need to improve your outlook on life in general. You are currently being useless and not contributing anything of value. Go away.

I agree, CM1 hardware and Yohan's communication - great.  Reputable (soon) - pending improved performance.


From this thread, its a couple of months, but production is ramping up, and so it should with them (based on 400-500 units) having taken over a quarter of a million dollars so far.

Once the developers get a working bitstream this will no longer be a speculation or development product (i hope) and we can make some hard and fast comparisons.

Judging by the rigor of the design and the forsight of enterpoint in using great cooling, I think we have the potential to see one of the best FPGAs on the market in the CM1.

kind regards

Yeah, sorry to bring up that guy's older post I didn't really want to get off track, but I believe he was making his comments under the impression he would get a $640 rate, or at least that he was ordering in "bulk". At $960 and with power consumption it is merely "competitive" with BFL. At $640 without complete software it's a "gamble", but one that more than just a handful of us are willing to make. As others have stated, BFL has only improved their delivery time from 3.5 months to 2 months in the last two quarters, they are pretty obviously not ordering parts till there are orders for them.


Well, I think there's probably several shades of reputable here, but as far as "delivering product at specified hash rate", you'd be right. BFL stills posts a 4-6 week delivery time but to my knowledge no forum member (aside from maybe Inaba or gigavps) have ever gotten a delivery in 6 weeks time, ever. I can't really comment on yohan's order to delivery speed because it isn't yet bad enough that users have had to post a separate thread for delivery times on them.

Any plans to release a controller upgrade HOWTO for Linux users? I've downloaded the 1.2 and 1.3 release and they only come with a Windows executable and Windows howto.
I don't have any Windows license available to me and certainly won't buy one and install Windows on my laptop just to upgrade the controller...

As a bad controller upgrade will make a board useless, I'm not willing to take the risks compiling SPIprog for Linux and poking around  (Edit: at least not without a known-to-work howto).

Whoa back there partner, Enterpoint make people wait months before delivery, then they are using a 'development' product, so 50 days minimum turn around from BFL easily matches the announced delivery dates of enterpoint, if you discount the fact the the CM1 is not performing as expected yet.


Yea, but you can go to a brick and mortar shop and get a porche.  A better comparison would be a Tesla roadster, alot of ppl put up heaps of dosh, then more, then waiting and finally got what they ordered.  Most if not all are over the moon with their purchase even considering the whole process.


They are not yet a reputable vendor.  They have yet to deliver on task.  They sound good to everyone in this thread ill agree, but most are feeling all warm and cushy about having a $640 1000mh/s device, thats why they have a predilection towards enterpoint.  It cant be for any other reason, as none of those users have what was intended yet (other than a pretty looking piece of hardware)

Reputable vendors are Ztex and Ngzhang, thats the list, period.  BFL is reputable as well, but lots will piss and moan about that, my point is all three of those companies do or have delivered plenty of working products to their users that meet or exceed expectations.  BFL was out by alot on power, and hasing speed, factor of x4 and currently 120mh/s short.  But ngzhang delivered, and now ztex are exceeding expectations with their 248mhz bitstream.

If you were really banking on reputation and delivery of performance, then you would be a Ztex customer, period.

kind regards.
