Thanks Kramble, I was googling "build Xilinx JTAG platform cable" which did not yield any helpful results.

I have a load of veroboard lying around and plenty resistors etc. Will maybe try and build one out of interest if I can dig out a suitable buffer / driver IC.

Sounds like you know what you're doing. Any CMOS buffer should do the trick (the idea is to do level translation between the 5 volt parallel port and the 3.3 / 2.5 volt JTAG). The reference circuit uses the 74HC125 (or 74HC244 used in the byteblaster-MV), but anything similar should do the job. It's not really worth the effort to be honest, as the USB platform cable is a lot faster and better supported (the document I referenced claims the series-3 parallel port cable is unsupported after ISE version 10, but it's working fine on 14.1 for me).

Good Luck

I have not been informed of any ASIC in production for Blake-256 until I do please regards such things as a scam or fake

and as proof on same day we are also going to have a UFO Landing which is just as likely

I'll try again What driver do I need to do to allow ubuntu to see the x6500 I do not see an entry in the /dev folder.

I failed to get an x6500 running with a Win 7 64b host. I have yet to try it under linux. What has been working fine for me is a 32b Windows XP virtual machine, python 2.6, and PyUSB 1.6 for python 2.6.

I just tried to get it going on Ubuntu 12.04.3 and failed. "No module named d2xx".

Undecided

Python 2.7 32 bit on win7 with Python 2.7 PyUSB-1.6

Well, we know that Blake was designed to be ASIC friendly. Scrypt was not, and yet there is a lot of action (or at least talk) about a Scrypt ASIC development. So technically, it's not at all unlikely, and it should be relatively easy after the generations of SHA-2 chips already out there.

However, it would be a big investment, so it wouldn't make a lot of financial sense at the moment.

I have ordered a programming cable on Ebay, but am too impatient to wait on it arriving! Kramble mentions on his Github that it's easy to build one but haven't found any obvious instrcutions after googling.

Google fu defecit?

https://www.google.com/#q=xilinx+parallel+cable+diy

My attempt was a lot cruder, one 74HC244 chip and a bunch of 100 ohm resistors, built on a breadboard. I later tidied it up by etching a PCB. Actually it was an Altera Byteblaster that I built, but it was easily converted to Xilinx by rewiring the D connector.

Anyway, as Blue said, if you've already got one on order, then it's probably not worth your time in building a homebrew version, though depending on your geekyness level, it may be fun. This is what you need http://www.xilinx.com/support/documentation/user_guides/xtp029.pdf

PS. Be sure to use the FPGA I/O Aux supply for Vcc (typically 3.3V). The old TTL 5V spec will destroy your FPGA.

Hopefully I will have the cable within a few days.

the home brew parallel cable I would not recommend especially when your cable is ordered Wink

the usb cable works out of the box with impact for programming Cheesy

can someone please post a .bat setup for r9 280x, and 7950 - i am having hard time to set them up
thanks in advance

Just use your old script and make a new config file for blakecoin. In the long run it helps with maintenance. Afaik you only need to change this to get some difference in hashrate:

Code:

"blake256": true,
"intensity": "14",
"gpu-engine": "1150",
"gpu-memclock": "1000",
"gpu-powertune": "20"

And remember, if cgminer is not running properly, add those variables in your start script:

Code:

GPU_MAX_ALLOC_PERCENT=200
GPU_USE_SYNC_OBJECTS=1

did you use the version from the getting started page for pool?

http://www.blakecoin.org/cgminer-alt-pool-eu.7z

remove these they are not used by the blake-256 kernel

-g 1 -w 512 --lookup-gap 2 --thread-concurrency 16384

max intensity is 14 beyond that no effect on performance

try this
cgminer.exe --blake256 -o stratum+tcp://eu1.blakecoin.com:3334 -u XXXXX -p XXXX -I 14 -w 256 --gpu-fan 85 --gpu-engine 1000 --gpu-memclock 600 --gpu-powertune 20 --temp-target 80 --temp-overheat 85 --temp-cutoff 92

Note: Blake-256 does not need high memory speed lower it as far as possible

or just edit cgminer.conf and then just run cgminer.exe (no switches) it will load from the conf

Put the above command into a bat Huh

or just use the cgminer.conf

if you have issues you might be trying to use scrypt options in your command!

Hi just to share my mining experience:
mining with the CGminer 3.11 mod and a R9 290 GPU . Speed is about 2.8Gh/s. win 8.1 64 bit, 8Gb RAM, CPU (dualcore Celeron G1610) is running 50% Sad

pool is eu1.blakecoin.com where now after many hours(due to the 140 Round Earnings confims needed) about every 3 hours > 10 Blakecoins start to drip into the 0.890 wallet.
so about 90 BLC per day.seems working smooth and GPU cool(due to the low 13 intensity?) .
R9 290 can run with Intensity 20 but CGminer 3.11 mod crasht when setting the intensity above the default 13 (which is more a 7950/7970 setting)

I am also mining with the same GPU and pool as yours but getting all the shares rejected, WU:0 . I am new to mining, Can you please share your cgminer setting. Thanks

I have an idea for pool owners: providing a stratum+tcp link to port 80 would be great for those behind restrictive firewalls

pool server needs exclusive lock on port can't share it with other apps like the webserver would need a proxy which end user could also do
