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

Thanks for the tips. It's working now. Cgminer downloded from ckovilas git will not hash with Icarus (Lancelot). Only version from Kano github does that.

EDIT: bfgminer also works! It needed only change from -S auto to -S COM3.

With cgminer that just depends on what you are running.

With the latest 2.7.5 that was just released:

When running windows:
If you only have FPGA and no GPUs, ckolivas has now added an extra FPGA only version in the windows binary download
(I made an ICA/BFL only windows version up until 2.7.4a but I don't need to do that now coz it's in ckolivas official version)
In ckolivas Windows 7zip file it now contains: cgminer.exe and cgminer-fpgaonly.exe
So I won't need to put a 2.7.5a.exe in my downloads

For others running linux:
It depends on your linux version.
ckolivas builds his on the equivalent of ubuntu 12.04 so it wont work if you have an older 11.04 or 11.10 linux
That's why I have an 'a' version in my git downloads that I compile on 11.04 (it also works on Fedora 16 and 17)
I haven't made 2.7.5a yet - I'll do that shortly.

Mine arrived today. Hurray!
After 5 days, not too bad. Piece of solid hardware. I'm trying now to force it to work but without any luck. cgminer, bfgminer don't recognize anything. I can see in device manager (Windows) additional COM3 port. I've set it up for 115200 baudrate, in .bat file added -S auto --icarus-options 115200:2:2. I'm more and more stupid Wink

It will of course (as you said) show up in the device manager unless there is a driver problem.
Since it was COM3, the extra option would be
-S COM3

The --icarus-options 115200:2:2 you specified is the default I set in the code anyway, so you don't need to do that one.

If there is more than one of them it is -S COMn -S COMn and for any of them if n > 9 it's -S \\.\COMn

My Lancelot board arrived on Monday. I have to say that it works fine.

@Dexter770221:
It is supposed that works on windows... I don´t have probe it but in fact ngzhang has write instructions to do it work on windows.
Because I had some problems recognizing the hardware and at the end the reason was the USB cable (A-type male to miniUSB male) I suggest you to change the cable and continue trying Wink

Might try (with 2.7.5):

Code:

bfgminer -S all

This will scan every serial port it can. Beware if you have non-mining devices on your PC, though!

Unfortunately, ngzhang didn't want to donate a Lancelot so I can provide proper support (he did donate an Icarus - I guess he assumed Lancelot would just work in the same way), so there may not be much I can do if it doesn't work unless someone else wants to donate one.

I could be wrong, but... Last time I checked scan serial wasn't working. Try calling com 3 as you see it in device manager and it should work.

Well, I don't want Linux. Not on minning rig, its been used for other purposes that requires Windows. So, "no go" with Windows?

The Dame of the Lake knocked at the door today and gave me that Lancelot board dev kit !

It's amazing. It took me a few minutes to make it working under Linux (debian 6):

- recompile cgminer with --enable-icarus
- search /dev for clues => /dev/ttyUSB0
- cgminer -O zzz:xxx -D -S /dev/ttyUSB0 -o xxxpool.com:8332

--------------------------------------------------------------------------------
Pool management GPU management Settings Display options Quit
GPU 0: 75.5C 2182RPM | 325.3/322.9Mh/s | A:232 R:0 HW:0 U: 4.68/m I: 4
ICA 0: | 379.4/376.7Mh/s | A:277 R:1 HW:0 U: 5.59/m

Fantastic work, the board is wonderfully built, thank you Ngzhang !

Hi Phil,

..
For finding non working Icarus units.. how about checking the idle LED?

...

Yes, this is the way I am doing it right now.
Repluging the USB cable will solve the problem normally.
But if you need to do this once a day, it is getting boring, because it is not always the same board.
So you have to check really all Icarus boards every time...

Thanks for the hint with the new Lancelot boards. Sounds promising...

Cu,

Eckmar,

The Lancelot uses the FTDI chip - which does have a serial number for each chip, you can program it by ftprog. That way your host can remember the port assigned to it.

about the price, there are 2 method to reduce it:

1, can be significantly reduce when the sales volume increase to 250. at that point i will change to -2C speed grade, and the price will reduce about 10%. but seemingly, the hashing speed will not reduce a lot(nearly the same).
2, buy more. a 30pcs bulk order can enjoy a 400$/ea price.

WHEN do you accept bulk orders for Lancelot?

I fear if the ASICs really will be available in October this year, your announced motherboard for Lancelot may never be produced. Sad

With my 36 Icarus boards running here in my pool, it is a burden to find one which is not running. (Which happens here once a day.)
So I would really appreciate a cluster with a software which is telling me which board is not working...

Any news about the new bit-stream for Icarus?

Sunny regards from the holiday island Koh Samui (Thailand),

any news about the bitstream and if you can sell Lancelots with Icarus bitstream?
i think this way the price can be reduced a bit Wink
