Hi, did someone allready tried the icarus board with p2pool? It seems that not all FPGA boards are p2pool compatible (at least the rumors say something about xtec).

I've been running Icarus with p2pool for some time, worked like a charm.

Allso i would like to know if industry or commercial standart spartan6 was used for the icarus board

I need the USB vendor / product ID.
idVendor 0x067b Prolific Technology, Inc.
idProduct 0x2303 PL2303 Serial Port
Perfect, thanks

Can someone tell me the vendor and product ID of the serial USB chip used in the Icarus? It's a prolific isn't it?

Awesome and psychedelic - scrolling that up and down the screen makes me dizzy.
I just read this and totally agree! LOL! Heavy shit.
Btw, I received today my 3rd batch icarus, its running fine! Awesome stuff!

Seems your win7 is not very stable. 
(just kidding)
(just kidding)It is working but not too stable for me with win7. I had 2 BSOD (bluescreen of death) in a row. I had to switch back to MPBM.

Hmm, it would be really cool if you released a Windows binary of cgminer with builtin Icarus support. Last time I tried the latest windows build it failed to work in spite of some people saying that supposedly icarus support is now enabled.

Went to the trouble of doing a little analysis of the Icarus performance
(Edit: using the simplistic assumption T = nH + W
where T = time, n = number of hashes, H = time per hash, W = software overhead)
Basically by generating a line of best fit using least squares.
Hash (H) time per hash (or pair) is 5.26ns (consistently across tests)
Thus MH/s is 380.23 (similar as stated by others)
Using my cgminer code the issue I though might be the actual overhead of setup and getting an answer (W) and that came out as ~0.014s ... or ~5.3MH
Since the average number of hashes per nonce is 2^32
Then you expect to waste 5.3x10^6 with every 4.3x10^9 Hashes or ~0.12% or roughly 0.5MH/s
So not much of an issue
Again with the above figures you get the nonce range time as 11.296 seconds (similar as stated by others)
Time now to optimise the constants in cgminer ...

Not sure how to compile it manually....
I guess it would be easier for me to install OpenCL. Where would I download just the OpenCL? I know it is included in the AMD stream SDK or the AMD driver package.

If you have an AMD/ATI graphics card, just install the latest driver. If you don't, then you'll have to research how to get an OpenCL driver for whatever you do have.
Try "disable-opencl" : true, in the conf file. I switched back to MPBM because the board locked itself up more than once with cgminer. So, it does work but it's not perfect yet !

IIRC there is an Intel openCL driver that just uses the cpu.
It won't be fast like a GPU, but I guess it's just for devellopers to test stuff.
It would be enough for you I think.

If it isn't a runtime/windows error starting cgminer maybe "-G" will stop the error?

Tubor, can you post your cgminer config file? I am having trouble running cgminer 2.3.2 on Win7 as well.
When I start, it says "OpenCL.dll" is missing. This is a Icarus only machine. NO GPUS. Do I still need the OpenCL?

At least for MPBM you don't.
No idea about cgminer however. Might be that you need a special GPU-less cgminer build.
You don't need it to actually mine, but if you are using a pre-built binary that includes OpenCL support you might need to have it on the machine (although it won't actually get used). If you don't want to install OpenCL, then you'll need to recompile cgminer with the --disable-opencl flag.
