According that ASIC's are already shipped, I would not invest that much in FPGA's anymore.

BTW, I didn't know there is a hashvoodoo bitstream for the icarus boards ? I thought maximum was the 180MHz stream ?

Possible one of on-board DC/DC converters failed to start.
Examine schematics sheets POWER and POWER_IO: https://github.com/ngzhang/Icarus/blob/master/Downloads/SCHinPDF/Icarus_V2.pdf
They connect PW_GOOD and EN signals of U5,U6,U9,U10 in daisy-chain so if one of converters failed all board remain unpowered.

Sure that the little black switch on the left is "on" ?

Hi guys, I have question about starting cgminer with this Icarus board.
I just connected one Icarus board to PSU and USB, fan is not moving, everything is silent, no leds, but Linux has found new USB device:

Code:

$ lsusb
Bus 002 Device 008: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

Results:

Code:

$ cgminer -S noauto -S /dev/ttyUSB0
All devices disabled, cannot mine!

What I am doing wrong? Fan should be off and it starting automatically?

I checked fuse after reading this http://en.qi-hardware.com/wiki/Icarus#Pictures and it's fine.

Icarus is DISCONTINUED anyway. we don't have any new updates even for Lancelots!
unless ngzhang think that every of these boards will be replaced by ASICs thus no new bitstream
worth to be implemented!
WRONG! i like those boards and i don't want to replace them.I don't even care for electricity Wink

V4 ..

will have a final bitsteam update next week(i hope). and completely change the architecture.
please wait for that before do any optimization effort.

Yeah, an update about the new bitstream for Icarus boards after 12th of July would be nice...

Sunny regards,
Ecki

Needs more jiggawatts

BitMinter client v1.3.0 released today. Now supports Icarus and Icarus-compatible FPGAs.

For quick notice:

One week ago the fuse on my icarus board got killed.

I exchanged the broken one (3,25 A/Voltage ?) for a 2A one i had around.
But i am still to find the cause why the original one got killed in the first place.

Anyone has experienced similar problems ?

Yes, I burned a fuse when I first got my Icarus when I was assembling the spacers. The screwdriver went across some contacts and shorted the fuse. The power switch was off but it was plugged in. Still had some current running through the area I touched. Better to always unplug everything. After replacing the fuse with a new one from Digikey the board works perfectly.

hi guys,
is this what we need to program icarus with new bitstream?

I think I met once. when I power off, power on the device. I am suing a 12V, 2A power adapter. after broken the fuse, I switched to ATX power.

BTW:
if there some picture about your '1.7kW solar array' and your mining farm ?

The farm is a bit boring, just a pc and 4 icarus cards. I will be building an enclosure for the icarus before summer to improve the 4x120mm fan airflow.

But I do have an old pic of my panels http://anonymouse.org/cgi-bin/anon-www.cgi/http://img713.imageshack.us/img713/4863/2011121318opt.jpg and batteries/inverters http://anonymouse.org/cgi-bin/anon-www.cgi/http://img828.imageshack.us/img828/1208/2011121318opt1.jpg
I have 2 additional 125w panels and 2 additional 60w panels now.

kind regards

Well after installing the icarus modules under 120mm fans, I have noticed considerable improvement in stability for the 200Mhz beta bitstream :

Code:

ICA 0:                | 399.8/395.5Mh/s | A:5618 R:22 HW:0 U: 5.55/m
ICA 1:                | 399.8/395.4Mh/s | A:5557 R:25 HW:0 U: 5.49/m
ICA 2:                | 399.6/395.3Mh/s | A:5530 R:29 HW:0 U: 5.46/m
ICA 3:                | 399.7/395.3Mh/s | A:5574 R:22 HW:0 U: 5.50/m

I use the --icarus-timing 2.5000=100 command line option and things seem to be working well enough.
All and all its about 1600mh/s for the 4 units and improvement of exactly 5% as per the increase from 190mhz-200mhz.

If I knew how I would like to do a 210 or faster and see what I could net. Unfortunately I have NFI

Looking forward to nzhangs announcement in regards to the new bitstream.

kind regards

it would also be great if Icarus can be programmed from PC via USB!
is it possible in the near future?

I also would like this, as it means that I can try the tricone stream and wouldnt have to fiddle with that damn xilinx cable.

i will release .mcs files for all bitsteams, unless it's a UNrecommended test bitsteam (like 200m beta).

The 200mhz one is the one I really want, Im running really good cooling.

Are your other bitstreams going to approach the performance of the 200mhz beta ?

kind regards

wait for a few days.
