Thanks Doc!
Good job. I like the way you keep us updated

Ngzang,

Is there any thing we can do to help you out? I mean to provide you some CPU power or other resource that you are missing?

All disk are complete crap! Two years ago was a whole different story. That was what a friend (who knows his things very well) told me. After six mounts they are all dead, Which reminds me that i have to by second one and build raid1 also:) Probably web server crash a day ago was caused by that also...Just sharing thoughts...Thank you very much for your immediate and adequate actions!

I am sure that you  will do it! At the end whatever it costs it will worth it. Believe me. The feeling after job well done can not be replaced with anything else expect with well-well done
Just a side question - do you plan core (or cg miner) to be able auto adjust the clock watching the error rate? Will be some temps reading be available? and PWM fan control and speed monitoring.
I know that it is too much for a start (first version) but i am asking in general for future bitstream upgrades

I mast say that i am not an expert but it seems that there is a lot of room available to fill Apart of the joke i have red somewhere that some of the guys do use "self made" tools to be able to achieve big density. The info was here if i remember correctly but link is dead

Super!

Thank you very much
I am Looking forward for it..

Hi,
I am using cgminer 2.7.5 I have restarted it just to make sure. But still i do not see anything related to X-Roll-Ntime. I guess it is not lunched yet. When X-Roll-Ntime is available for all of us i will ask you to confirm it here. Then will know that something is wrong with our setup and there will be no doubt that pool supports it.
Thank you very much in advance

flynn,
Thanks for the update. The wise thing we can do is to wait for ngzang instructions - personal opinion. I think if we do something wrong we can "kill" the boards . More over there are some switches on the pcb prog1 and prog2. I personally do not have enough knowledge to look at the pcb files and find out what they are used for.
If someone else has the guts to try it and share the info with us will be great;)

That is outstanding!
Thank you very much for the efforts:) We will increase efficiency of our rigs!

DrHaribo,
Are there any news/progress with roll-n-time support for cgminer?
Will this feature be available soon?
10X

Thanks kano!
Just a side question. I am using bitminter for the moment. as far as i know roll-n-time will come shortly but there is no support for cgminer yet. Pool works great. Can you tell me which pool do you use with roll-n-time enabled for cgminer please? I hope it is not top secret of course:)

Kano,
I have noticed a couple things:
1. You are running both GPU and FPGA on your cgminer. Is it a good idea to have them both on single miner? Are there some potential problems because of that? Currently i am having two cgminers running - one with GPU disabled and icaurs enabled and second cgminer with GPU enabled and icaurs disabled
2. Your cgminer version is 2.7.5c is it just a string bumped up right? what i am asking is if https://github.com/kanoi/cgminer/ contains your latest code?
3. Your HW errors are a lot less than mines:) However i am not done with hardware setup yet - i have to polish it, Voltage drop of the second crappy PSU is big about 1.3 volts. I suspect some of the usb cables that came along with the usb hubs i bought. They just look like a pice of garbige compared to ngzang USB cables that came along with lancelots.  In general  my HW errors for all Lancelots are < 0.3%, but i have some boards with almost 3%. It is just one night run of course.

spiccioli,
udev works charming:) you made my day thank you

kano,

I just cloned
https://github.com/kanoi/cgminer/

It turns out that if (hash2_32[7] != 0) means hw_error not like the patch i found:)
Share below target is not always hw_err right? Anyway thank you for your work. I am running your code right now and i will let you know how it goes. Bad thing is that i have HW errors counters>0 I am joking..I guess i have to live with them like everybody else here.
Everyone was talking abut HW error rate - % - Now i can calculate and graph it:)

Best

That is what i was looking for:)
I will try it later and let you know the result!
Thank you
PS:

What do you think of HW err patch listed here?
https://bitcointalk.org/index.php?topic=78239.1760
Assuming i am having only ICA boards attached it can not brake anything right? And will count HW errors. Actually i applied it already and seems good.

Guys,
I am tiring to map my lancelets to particular names in order to be able to know which cgminer ICAxx corresponds to which board. I am using xubuntu 12.04.
I have tried following (udev rules):
ATTR{idVendor}=="0403",ATTR{idProduct}=="6001",ATTR{serial}=="A101LSVA",SYMLINK="ttyLancelot2"

When I tested it the serial A101LSVA corresponded to /dev/ttyUSB2 with board attached and working

However /dev/ttyLancelot2 always was symlinked  to /dev/bus/usb/003/026 or something and cgminer refused to work. When I manually symlinked /dev/ttyLancelot2 to /dev/ttyUSB2 all was fine. How to make udev to symlink to /dev/ttyUSBxx instead of /dev/bus/usb/xxx/xxx
10X

I know:)
I have read that already --icarus-timing. Th question was if someone have done it already. I just do not want to "kill" my board if i make something wrong while flashing it:)

Guy's
While waiting for ngzang Lancelot bitstream i wana play with one of my boards  and try different bitstreams. I just wana be prepared for the moment when ngzang will release the official bitstream. However i have never done that before. I have a couple of questions and i would be thankful to anyone who can give me some info:

1. I have Lancelot dev kit available.
2. Are the instructions published for Icarus http://en.qi-hardware.com/wiki/Icarus#Flash_by_using_iMPACT,  http://dl.dropbox.com/u/28686048/Icarus/prgm-fpga.png, https://github.com/ngzhang/Icarus/blob/master/Downloads/bitsteam/guide%20for%20flash%20update.txt good to be used with Lancelot?
2. Have someone tried https://github.com/ngzhang/Icarus/tree/master/Downloads/bitsteam/200MHz_for_test or https://github.com/ngzhang/Icarus/tree/master/Downloads/bitsteam/V4 with lancelot?
3. What other "unofficial" bitsreams are available for Lancelot
4. How can i flash "temporally" bitstreams - i mean mcs files. As far i understood flashing mcs do not last power off/on? Probably this is the bet way for me to try.
5. I am using cgminer 2.7.5

Thank you very much in advance

I am not complaining just trying to help. Posting the potential problem.  Besides i think that each one of us shall donate (I am donating) to help the pool stay alive and improve.

Here Dead also...

Seems like somebody is filtering the port  - ISP/Backbone on the way or mint.bitminter.com itself...

Dude,
First use apt-get install. When i was young i was trying to compile everything by myself. I realasied that i can not maintain whole linux distro
I am joking.

Did you read cgminer/Readme
did you apt-get install
libudev headers
        (This is only required for FPGA auto-detection and is linux only)

        libusb headers
        (This is only required for ZTEX support)


Just goolgle about apt-get install ftdi_sio i guess you miss libusb-dev (if there is such thing) or something else which for sure can be installed with apt-get

Good luck
It shall be somewhere inside:)

For your reference my distro is same is yours
