Okay now I'm convinced there's something seriously wrong with my two Cairnsmore1 boards.

After trying again today to get them working at full speed, I was flashing Rev 1.2 onto both of my boards using SPIProg.exe, I turned the power off to the boards, then turned it back on. I noticed that one of my boards had different LEDs lit to the other board, even though they were using the exact same documented DIP switch settings (http://www.enterpoint.co.uk/cairnsmore/CAIRNSMORE1_SPI_PROGRAMMING_DIP_SWITCHES_SETTING.jpg).

I tried powering off and on again, and strangely enough, the LEDs matched this time.

I tried it again and they were different again.

To be honest I have no idea what is going on now with my boards. It appears that the controller is not being flashed correctly and that it is reverting back controller revisions after power cycling? Or something possibly could be wrong with my DIP switches and they are malfunctioning?

Either way, all I have at the moment is two very strange boards that net 100Mhash/s each if i'm lucky.
I hope Enterpoint can get this sorted out soon??

Since changing the USB cable as suggested, I've been running the board pretty solid. I grabbed it from my WD external drive from a few years ago with a USB extension since it's a short cable. I ordered some new ones and will try those out when they come in.

Are you sure it was the cables? i have boards that disapearing every several hours, i also tried other cables, but it didnt help.

I had the issue where they would disappear every 15-30 minutes. Once I changed out the cable, each chip is up to 4500 shares with no issues. Prior to that, I would be lucky if it hit 1500 shares.

I went from a Win7 (64) Llano APU laptop, that had a usb port for each CM1 I have.
- It was unstable and would be lucky to last 1-2 hours before com ports disappeared and it stopped mining.

I changed over to a Ubuntu 12.04 Open case Intel Atom, that had to use a 4 port hub (no seperate power) to operate them, due to low number of unused usb ports.
- It has been stable for 24 hours+ first attempt. It's still mining and has been no hassle since.

So the things that changed;
- I changed the OS (Win -> Linux), this obviously effected the system it worked it alot, aswell the drivers.
- I went from a Laptop to a more traditional PC board. It is a lot less powerful of a system, but for the first 12 hours was dedicated to just mining. Later it proved it didn't need to be dedicated, since it still worked fine multiple times to play films, music etc fine while also mining.
- Direct Usb cable to usb port to having a usb hub (this should of been a negative), but appears to had no effect. However their is only 2, maybe the effect would of been worse had I had more on this hub and it not having it's own power source.

For me, It worked moving to linux. For others it works to change their usb cables etc, that was all they needed to do.
Cgminer team has actually made a guide or two on this, if your unsure what or how to do it, check the software subforum.

I did not yet switch over to my linux machine (igel-5/3 (via c3 1ghz passive cooled) thin client with debian squeeze on sd card).

After some hours of stable hashing rates using a dual usb cable on a Thinkpad T500, I accidentally disconnected the dual usb cable from the micro usb cable. I did not succeed in reaching stable hashrates again.
So I tried a powered hama usb 2.0 4-port switch, again using dual usb cable for more usb power, but no success in reaching a stable hashrate.
I don't think my cheap chinese ac adapter is the cause of my unstable hashrates, because a friend of mine is using the same ac adapter model and has stable hash rates.

Tomorrow, I'll switch over to the linux box. If this won't help, I'll buy some RAM to revive my now defunct desktop PC.

Today I was able to get the Enterpoint cairnsmore to work with the tricone mining software without needing an isolated stand-alone cable, just the FTDI link. The code is still early in function, and still suffers from some JTAG errors likely due to noise / reflections on the lines which will need better error handling. I only performed several tests, but was easily able to get stable function with three rings at 100Mhz. (150 Mh/s).

I will keep you guys updated, I should have more time to work on it on Tuesday.

Here's some brief logs from submitted shares, it's fairly garbled from the ascii formatting for the colors.

Okay now I'm convinced there's something seriously wrong with my two Cairnsmore1 boards.

After trying again today to get them working at full speed, I was flashing Rev 1.2 onto both of my boards using SPIProg.exe, I turned the power off to the boards, then turned it back on. I noticed that one of my boards had different LEDs lit to the other board, even though they were using the exact same documented DIP switch settings

norulezapply,

this is a bug of revision 1.2, sometimes when starting up you get blue/red leds light up.

If you flash revision 1.3 this problem is fixed.

Today I was able to get the Enterpoint cairnsmore to work with the tricone mining software without needing an isolated stand-alone cable, just the FTDI link. The code is still early in function, and still suffers from some JTAG errors likely due to noise / reflections on the lines which will need better error handling. I only performed several tests, but was easily able to get stable function with three rings at 100Mhz. (150 Mh/s).

I will keep you guys updated, I should have more time to work on it on Tuesday.

Here's some brief logs from submitted shares, it's fairly garbled from the ascii formatting for the colors.

Code:

nice one! But only with one fpga? What OS you use? If windows then please can you provide the patched urjtag prog.? The code of tml would be also nice. Wink

Hmm.

The reason I was trying 1.2 was because I'm not getting stable or full hashrates with 1.3.

If it is just a bug with 1.2, how come the same thing is not happening with my 2nd board when I flash it with 1.2? :S

All 4 FPGAs work, just a testing run post. I'm doing it under linux, but it should work fine under Win32/Mac/Linux. The code actually doesn't use urjtag, but just the modified tml code and FTDI driver.

It should be much more useful once the JTAG issues are hammered out.

yesterday, I observed a startup issue with controller rev. 1.3:
I connected power, the controller led did blink as usual, but none of the fpga leds did light up.
I thought "there must be something wrong" and just reconnected the ac adapter without further investigation of the situation.
since then, I re-powered the device between five and ten times without any startup problems.

of course, my instable hash rates didn't improve by any re-powering of the device... but now it's time to test a linux box .. it will surely be better than the 20MH/s I'm getting right now using t500/win7 laptop.

I've been following this thread very closely as i'm interested in making a bulk order.

So far, it doesnt make any business sense now. If you think this as an investment, then its terrible. How many ppl have got these board worked at intended speed? and if you did, for how long? I'm not a technical person but spending a month of tinkering is not acceptable. Maybe we should now know why BFL had a long waiting for their production.

As a potential customer, may i know exactly why you sell the boards without a working bitstream?

I know it won't be easy to convience you otherwise of your view. How ever I will do my best to try.

Quick turn around, they are using the same chips and a similar design than what is already been done. However the made it a bit bigger, using 4 chips. Enterpoint are veterans in the market of making FPGA's, but relatively new to bitcoins, it was their first board. They made it from scratch quicker than any other manufactor, so I got to give them credit there. They had lots of people interested in seeing this as a development board, even if it meant us making the bitstream, so they went ahead with it.

A fully working bitstream was not the problem it should of been, it was a oops in the complication of combining 4 of these chips. It was a calculated risk and hasn't turned out that bad. If I had made orders with another manufacter, I know it would of cost me more, also I'd paid in advance for most of them (not all) and many of them I'd still be waiting for my product in hand. To me, I've come out better off for it. I don't like waiting 3+ months for an item, I certainly don't like waiting that long for an item I already bought. Enterpoint delivered what I expected.

Enterpoint (Yohan) and his team with the CM1, it allowed us to be mining on a development board, which we knew about in advance when we order at a lower than normal price. We saved money buying hardware and only paid when it was ready to ship.

As a programmer/developer this does not bother me, sure there are a few frustrating moments, that is part of being a programmer, you get little irratiable when debugging a problem. Many in this thread are also very technical people, that is the target whom jumped in early before a bitstream was fully ready. The FPGA market is filled with people just like me, so it does make business sense, it did work, he sold quiet a lot of them.

Average Joe, sure this might not be ideal for you, unless you prepared to start learning all what it takes to get a FPGA to work. It's not plug and play, anything more advance than a GUIminer is not, so it should come to no suprise that these won't be.

It was sold as a DEVELOPMENT BOARD.

If you had really been following the thread "very closely", you would know this.

BFL is completely different. They have a working bitstream already, and they take money upfront, without shipping anything for months after the quoted delivery time. If you'd rather buy from them, go ahead I say. Enjoy waiting months for your board for no reason whatsoever other than incompetence...
