You need to do a modprobe.

Plug them in then issue this command:

Code:

modprobe ftdi_sio vendor=0x0403 product=0x8350

FYI, this is not required if you added the udev rules posted by yohan at the CM1 support pages.

I've done this and it doesn't work for me, so I have to use modprobe manually

Have you got the latest ftdi drivers?

I suppose I do, I installed libftdi1 and installed the D2XX FTDI ARM drivers (not sure if these last ones are needed, but I installed them anyway)
dmesg show "ftdi_sio: v1.6.0:USB FTDI Serial Converters Driver"
yet, I don't get any /dev/ttyUSBx devices either (only /dev/usbdev1.1, /dev/usbdev1.2 and /dev/usbdev1.3)

I'll fiddle a little further...

I don't get them showing up either.

You need to do a modprobe.

Plug them in then issue this command:

Code:

modprobe ftdi_sio vendor=0x0403 product=0x8350

Then you should see the ttyUSB0/1/2/3 etc. for your Cairnsmore1's

Hope this helps!

Just a quick update.. I was able to get one of the FPGAs to run stably at clocks of 160,160,160 -> 240 Mhash/s.

I'll keep you guys updated!

Quick update on my progress with the enterpoint board..

I've now got the FTDI chip working effectively with onboard JTAG. Unfortunately similar to the issues other bitstream developers have mentioned, the clock coming from the controller is too dirty/skewed and causes the DCM to lose the lock fairly frequently. So currently the board can find and submit shares, but quickly loses the clock source. 50 vs. 100 Mhz doesn't appear to make a difference.

This was validated with a version which checks the lock every 60 seconds, and it will rarely make it beyond 1 minute.

Have you got the latest ftdi drivers?

I suppose I do, I installed libftdi1 and installed the D2XX FTDI ARM drivers (not sure if these last ones are needed, but I installed them anyway)
dmesg show "ftdi_sio: v1.6.0:USB FTDI Serial Converters Driver"
yet, I don't get any /dev/ttyUSBx devices either (only /dev/usbdev1.1, /dev/usbdev1.2 and /dev/usbdev1.3)

I'll fiddle a little further...

You have to have a powered USB hub, and you also need a really good power adapter, otherwise it will draw too much from the PI and cause those errors and not bring up the serial ports. I got it running with my PI and eventually took it offline because it would randomly crash due to power draw. I'm waiting to get a good power adapter from Adafruit.com.

ebereon,

how many boards do you have running per instance of cgminer?

EDIT: I've gotten 8 boards running fine in 2 instances of cgminer (any more than 4 per instance crashes it for some reason???) but I can't seem to get my 9th to get detected.

as per Ebereons instructions, I've identified the boards usb's. I've uninstalled w/ and w/out deleting the drivers, and w/ and w/out uninstalling the com's ports associated w/ the board. Each time, the board re-installs to the same coms, which gives me

[2012-08-04 21:39:32] Started cgminer 2.6.2a
[2012-08-04 21:39:32] Icarus Detect: Test failed at \\.\COM20: get 00000000, should: 000187a2
[2012-08-04 21:39:32] Icarus Detect: Test failed at \\.\COM21: get 00000000, should: 000187a2

every time. No clue where to begin figuring out this issue, any help would be greatly appreciated.

Thanks,

Steamboat

I don't use cgminer yet, just tested it after mpbm was working without problems. Make sure all boards accept the 190Mh bitstream, best joice is mpbm and check 1 day the invalids. If you have invalids >3% on some pair, use a slower bitstream. If now all works in mpbm with <3% invalids, then i'm sure all boards will be working with cgminer too.

I'm trying to get my Cairnsmore1 run on a Raspberry Pi (cgminer), but I'm getting these type of errors:

[2012-08-05 09:38:57] Icarus Detect: Test failed at /dev/usbdev1.2: get 12010002, should: 000187a2

I then tried on a Linux machine, and I get the same type:

[2012-08-05 10:17:12] Icarus Detect: Test failed at /dev/ttyUSB0: get 00000000, should: 000187a2

on Windows it mines without problems. Anyone an idea on how to fix this?

I think your error is mine . I run one board in one cgminer . Could you check if after error lines you posted ,do show up other for a little time telling you something about user privileges Huh

Try to unplug usb from all your boards( better in ubs hub) , then power off PSU, wait a couple of minutes (cold?¿? your board) and then power on PSU and first plug usb of your problematic board. windows should detect it.

Im almost sure in my case is a temp or usb hub issue. because sometimes when board is frozen ( amber leds) it start to work again but other different fails suddenly.

NOTE: frozen for me is when you have your COMS ok and cgminer is not showing OFF state. but lots of LONGPOLL's and amber leds in the fpgas you have programmed.

Please tell me if it works for you.

Next week I'm going to buy some extra fans and i'll post if they fix my problems.

it turns out that mucking with clocking like that affects how ISE maps, places and routes everything for some reason

Thanks for the clarification. Fortunately for me I never had the problems with on-board signals but only with off-the-board comms.

I don't have the CM1 hardware, but I watch this thread and I have to ask:

Why not using PLL_ADV in front of the DCM to filter out the jitter? Just from looking at the floorplan of Spartan-6 the PLL_ADV block is about twice the size of the DCM block. With BANDWIDTH=LOW it should serve as a decent jitter filter.

I've actually got some changes locally to try and do that, but it turns out that mucking with clocking like that affects how ISE maps, places and routes everything for some reason so I'd have to do another long SmartXplorer run - and it's possible that after all that the clock issues would be severe enough that the PLL wouldn't lock either. Since these boards are apparently wired for differential clock signals it probably makes more sense to wait until those are available and try using the PLL with them if they're still not low-jitter enough.

Update on latest bitstreams after 4 days:
Total 40 FPGA's = 10 boards SN#400+.

Makomk's dcmwd2 oc bitstreams:
17x 200Mh, 22x 190Mh, 1x 180Mh. That means 97.50% of all fpga's running @190Mh+ with <2.8% invalids!

Working bitstreams in percent:
200Mh oc = 42.5%
190Mh oc = 97.5%
180Mh oc = 100%
170Mh oc = 100%
160Mh = 100%
150Mh = 100%
140Mh = 100%

Update Glasswalker's bitstreams:
not changed will update when new bitstream is out

HowTo deinstall drivers completely from device manager in windows 7:

First:

This will enable to see all drivers in the device manager that are not used but still installed.

Code:

Name: devmgr_show_nonpresent_devices
Value: 1

Next open device manager and click this:

Then you will see grey entries like this:

Right click a grey entry and chose deinstall:

If you want to deinstall that driver comletely from windows, check the option:

Now make this with every device you want to deinstall from windows and you can start again to install. This works for me on every attempt when i had problems with a driver. I had this when i was playing with libusb.

You can also don't check the option to deinstall completely, just deinstall the device, in this case a replugin of the device will cause new COM selection for this device. In most cases this is enought to get the Cairnsmore working again.

I hope you find this one usefull =)

Speaking of resetting boards, these bitstreams should hopefully detect one of the common causes of FPGAs freezing (the DCM losing lock and not outputting a clock anymore) and automatically recover from it: http://www.makomk.com/~aidan/shortfin-dcmwd-20120803.zip Initial signs are looking good, touch wood.

In getting my rig up and running I've run across an issue.

Up to board #5 everything went relatively smoothly in flashing the makomk 190 bitstream to SPI. however when I went to flash the 6th (which went well) and plugged everything back in, the 5th was not able to detect one com. I unplugged the USB and plugged it back in and both coms on #5 stopped responding. unplugged #5 and reset, plugged back in, and still nothing. Unplugged #6 and tried again, still nothing. Plugged in #5 solo and nothing. Deleted #5's drivers and reinstalled and still no response on any of the COM ports.

It was working fine until I flashed the 6th (with all other boards disconnected) and decided to stop responding. I've reset, rebooted, switched out usb's, switched hubs, tried with multiple cards and just the single. All the other cards run fine, just #5 w/ the issue.

any ideas?

also, Win 7 64 w/ the latest cgminer build.

Thanks in advance,
Steamboat

This sounds a bit like the FTDI issue I described yesterday. I don't have the full details but there is a utility from FTDI to do a clean-up which followed by clean install might solve the issue. Normal uninstall doesn't appear to be enough if it is this. I think some registry entires are left that cause the issue and hence the utility. I will try and get more details of the how and what on this on Monday.

On a more mundane level have you tried a complete power-off and boot as opposed to reboot and clean plugin and bring up afterwards?

I completely shut down, unplugged the usb, unplugged power to the CM1, plugged in the power again, turned on computer, plugged in usb. no-go

Ok I will try and get more info on this on Monday but as usual I would recommend you send an email into the bitcoin.support email as a backup so that all of the team see what problems you have.

sounds good. I'm going to continue flashing the rest of the boards and come back to #5. Hopefully it's the only one w/ that issue.
