Not sure if I should post here or in the cgminer thread. But since I now have 3 x cairnsmore1's whirring away rather happily, I thought here was more than appropriate :)

After receiving the boards, things proceeded rather satisfactorily; my raspberry pi appeared to recognise the cairnsmore1's with little fuss (via my Plugable 7 Port High Speed USB 2.0 Hub). Indeed, after running:

$ modprobe ftdi_sio product=0x8350 vendor=0x0403

I get 12 usb devices listed (/dev/ttyUSB0 though 11), and dmesg reports thus for each:

[  121.752887] ftdi_sio 1-1.3.6:1.1: FTDI USB Serial Device converter detected
[  121.753086] usb 1-1.3.6: Detected FT4232H
[  121.753108] usb 1-1.3.6: Number of endpoints 2
[  121.753124] usb 1-1.3.6: Endpoint 1 MaxPacketSize 512
[  121.753138] usb 1-1.3.6: Endpoint 2 MaxPacketSize 512
[  121.753152] usb 1-1.3.6: Setting MaxPacketSize 512

So it all appeared to be going swimmingly well!

Rather taken by my success, I merrily downloaded cgminer. After compiling it successfully (with icarus support enabled), I ran it thus:

cgminer --disable-gpu -S /dev/ttyUSB0 -S /dev/ttyUSB1 -S /dev/ttyUSB2 -S /dev/ttyUSB3 -S /dev/ttyUSB4 -S /dev/ttyUSB5 -S /dev/ttyUSB6 -S /dev/ttyUSB7 -S /dev/ttyUSB8 -S /dev/ttyUSB9 -S /dev/ttyUSB10 -S /dev/ttyUSB11 -o http://poolserver:port -u myuser -p mypass

Unfortunately, my troubles began (and ended) there. Because unhappily, I was given the rather unsatisfactory news that:

I have seen mention of said problem on other threads. But alas, no solution proffered. Any ideas how one might go about solving this?

After reading the Cairnsmore Quick Start Guide, (https://en.bitcoin.it/wiki/CM1Quickstart#Enterpoint_CM1_quickstart_guide), I realised that SW6 should have switch 1 set off. After having done that, 6 of the usb ttys seemed to continue failing:

[2013-05-14 18:43:44] Icarus Detect: Test failed at /dev/ttyUSB0: get 00000000, should: 000187a2

But the other 6 seem to work!

ICA 0:                | 394.8M/394.9Mh/s | A:6 R:0 HW:0 U: 2.36/m
ICA 1:                | 387.2M/376.2Mh/s | A:5 R:0 HW:0 U: 1.96/m
ICA 2:                | 388.2M/374.9Mh/s | A:6 R:0 HW:0 U: 2.36/m
ICA 3:                | 387.5M/373.5Mh/s | A:3 R:0 HW:0 U: 1.18/m
ICA 4:                | 391.4M/394.6Mh/s | A:7 R:0 HW:0 U: 2.75/m
ICA 5:                | 390.6M/376.5Mh/s | A:3 R:0 HW:0 U: 1.18/m

Indeed, adding up the advertised hash rates for the 6 devices that appear to be working, I seem to arrive at something like the hash rate I was expecting to receive:

394 + 387 + 388 + 387 + 391 + 390 = 2337 Mh/s.

So I'm a bit confused. But hey, I appear to be mining! Yay!

Er, is this behaviour expected?

You have only 2 COM's per CM1 so 3 x 2 = 6 everything is fine :)

The other 2 are for programming.

The CM1 uses 1 COM for 2 FPGA's like Icarus.

Happy mining with these, i had 50 of them and they worked perfectly after we got good bitstreams :)

There are two versions of firmware for cm1s. One uses pairs, the other identifies each fpga. It's been a long time since I've messed with them, so I can't remember exactly which is which, but I believe glasswalkers is the one that uses 4. There's a cm1 users thread buried somewhere with all the info

Steamboat is right!

The shipped bitstream uses only 2 COM's for hashing and the Hashvoodoo (glasswalker) uses 4 COM's with auto clocking up tp 220Mhz.

Are you suggesting that I could double the hashrate by flashing with the Hashvoodoo firmware and thus use all 4 fpga's? Or at the very least, up the rate?

Forgive my ignorance.....

No the hashrate wont double.

With the shipping bitstream you have 2 * 380Mh/s per board, with the hashvoodoo you will have 4 * 150-220Mh/s (up to 240Mh/s with the hacked one).
Sure with the hashvoodoo you will have a better chance to optimise the hashrate for each fpga. so 800-960Mh/s per board (my boards run an average of 850Mh/s). And it will clock down on overheat too, so nice protection from damage.

Got it - thanks Ebereon :) Where can I hunt down hashvoodoo?

https://github.com/pmumby/hashvoodoo-fpga-bitcoin-miner

That it?

Yup

50! Quality :)

That seems to suggest you're now mining with something else instead?

Excellent - ta :)

sold in time and now waiting for avalon b#2 :)

Good luck with that.....

hi guys ! I'm running on win 7 and got an Icarus compatible board and guess what ... ? :) the cgminer doesn't see it .. only see gpus .. .so I tried with the 3.1.1 no gpu version and still nothing ... done the zdig driver thing and ... nothing ... tried a few more usb to com drv but to no avail ... anyone know a way to get it mining ?

hi


I have same problem on raspberry pi when I try run cgminer i have this error:
 Icarus Detect: Test failed at /dev/ttyUSB0: get 00000000, should: 000187a2


thanks for any advice

This most likely a bad USB cable, or your Bitstream needs to be reloaded. Is this a Cainsmore or an actual Icarus? if its an Icarus then cable and or USB hub is probably the issues. With the Cainsmore it really wants a Powered USB hub, and good cable, also make sure you are putting the bitstream on with a good cable and a laptop with a powered USB or an external powered USB.

Hope this helps.

Doff

thanks for your advice i used ztex fpga
I solved this issue I just forgot add --enable-ztex by cgminer compile ;)

now all is fine

And 2 days later they're shipping ;)

Anyone tried this with the original Icarus?

Congratulations :)

Tried what?

Sorry, hashvoodoo firmware, can I flash one original Icarus with it?

No, the Icarus have a different pinout RX/TX and different clock. The Cairnsmore have a controller fpga for this and it needs the hashvoodoo controller bitstream flashed to it.
You can't do this with Icarus, sry  :-\
