[ANN][BLC] Blakecoin Blake-256 for GPU/FPGA With Merged Mined Pools Stable Net

[ocminer]

Pool for Blakecoin still open for miners:

https://blake.suprnova.cc

It runs the latest MPOS with all its features including Idle Worker Notifs, two factor Auth etc.
I've got Stratum with Vardiff running on it, I've already found several Blocks while testing so everything should be fine, I just need some testing with higher loads.

You can use kr's latest cgminer and, of source, the FPGA miners too.

I'd be willing to help with this as ive always been interested in getting it working. a good idea if you are good with sql is to work out the sql structure (and the configs in use) here: http://github.com/60E/php-mpos

About the worker auth, i have a module in my repo which will get eloipool to use the database to authorise users. Eloipool will also likely need the db query modified to work efficiently with MPOS or you will run into a lot of cron errors (i ran eloipool before i began work on stratum)

Awesome this might help thanks 

any other help, tips, tricks most welcome

will add that auth module to eloipool

no problemo im in #cryptopools on freenode irc if u need any help fast (theres a few other pool ops in there too).

trying to get blakecoin .bit/.mcs on icarus fpga. ise impact isnt succeeding at initializing jtag chain. i think ive narrowed the problem down to either
1) Com port issue, either driver or mobo configuration
2) impact version, 14.7 doesnt seem to support the correct spartan6, do i need to use older version like 13.2? does 32bit/64bit make a difference?
3) perhaps icarus needs to be reset first, is it possible the previous bitcoin code is running and preventing jtag communication?

thanks for any help

14.7 works fine here, what cable you using and have you double checked the pinouts for jtag cable?

for Lancelot I do this

1. connect power to board (leave off)
2. plug jtag cable in (Xilinx usb jtag make sure its connected and installed status light should be red)
3. power on board (status light will turn green from red)
4. start impact and select create new then set configure device using boundary-scan (jtag) - Automatically connect (default)
5. should get a chain of 2 chips click the chip and assign the bitstream (mcs is not really needed at this stage only for long term e.g if asked to assign mcs for flash select no)
6. program both chips with the .bit should be quick
7. disconnect jtag cable (dont power off board!)
8. connect usb cable to the board and fire up cgminer (check device manager for port number)

example
cgminer-lancelot-52 --disable-gpu --icarus-timing 1.0=20 -S \\.\COM7 --url stratum+tcp://ny1.blakecoin.com:3334 --userpass User.worker:password  --cainsmore-clock 160 -Q 4

if all is ok it should be working and getting accepted shares

[bzyzny]

i get stuck at step 4, it does not show the 2 fpgas after i run initialize chain, instead it gives this error:

ERROR:iMPACT - A problem may  exist in the hardware configuration. Check that the cable, scan chain, and power connections are intact, that the specified scan chain configuration matches the actual hardware, and that the power supply is adequate and delivering the correct voltage.

the led on the xilinx programmer turns green when i power up the fpga. impact appears to recognize the device is there, based on the log output, but im at a loss as to what is preventing the jtag chain from initializing. I even tried doing it on a different computer (with windows 7 32bit) and a different version of ise (14.2).  any steps i can take to narrow down the problem? thanks

[bzyzny]

i noticed theres a large concentration of miners on eu1 pool. it would be good if people could spread out some, eu2 sg1 and the ocminer pool are all pretty much empty.

I want to join BlueDragon in thanking you for lending some real help on the development side of things.......

Could you post that part of the log, it may give some insight on the problem?

Stating the obvious, there seem to be three possibilities:

1. Faulty cabling
2. Faulty programmer (or less likely a software/driver incompatibility)
3. Faulty icarus

The icarus uses a different (14 pin) JTAG connector to the lancelot's 6 pin, but looking at the icarus schematic, it seems to have two additional 6 pin connectors (both on one side of the heatsink). Be sure that you are NOT connecting to those!! Unlikely I know, but worth putting it out there just to be sure (from the schematic, it looks like it these connectors would in fact supply the correct VCC/GND levels, so they could confuse the programmer into giving a green light!).

If you have access to another JTAG device (eg a CM1 or even some random non-mining kit), you could try connecting to that in order to rule out a faulty programmer (no need to do any programming, just check that a scan chain is detected).

some pictures of your setup might help us spot anything that is not connected right

i noticed theres a large concentration of miners on eu1 pool. it would be good if people could spread out some, eu2 sg1 and the ocminer pool are all pretty much empty.

I bet the pool operator is preparing a 51% attack

Just increase the mining fee and people will switch. Also I dont think we need 2 eu pools right now.

[mogrith]

on ny1 right now. I had problems with sf1 and just switched to ny1.

[BlueDragon747]

EU1 is one of the only pools with a fixed fee and it is very unlikely I would 51% attack my own blockchain  

EU2 is using the newer MPOS and is more stable will leave it as is for now, SF1 is still down not rebuilt it yet been working on merge mine stuff

Note: 51% is not an issue if the pool operator is trusted (I am not going to attack or double spend on my own blockchain) but it is a target for DDoS so make sure you put a failover pool in cgminer or use one of the other pools

[bzyzny]

Heres the log output from impact:

The programmer is a dlc9g, any other info you need?

[mogrith]

Just got this in the mail.  Need to get a 14 pin jtag connector?

[bzyzny]

mogrith yes just make sure you get a 2mm 14pin header that fits your cable. if you have success please share your info since im trying to get one of these working too

[BlueDragon747]

I would double check the pinouts on the cable between the programmer and the board I think thats why iMPACT does not detect your chain

[kramble]

Ah, I didn't realize these boards did not include the JTAG connector (which also raises the question of how they were programmed in the first place? Bed of nails or factory programming of the SPI ROMs I would guess).

Bzyzny, if you soldered your own connector, then check for dry joints or shorts. It's possible one of the signal pins is open-circuit which would be consistent with the error message. Also the socket orientation, but that's less likely as it would swap VCC and GND (the entire odd row of pins is connected to ground, the even row has VCCAUX and the four signals TMS, TCK, TDO, TDI on pins 2,4,6,8,10).

The schematic is at https://github.com/ngzhang/Icarus in Downloads/SCHinPDF (you can't view it on the web, need to download the entire git as a zip file). The JTAG connector is on the first page of the PDF, at the top left.

[BlueDragon747]

maybe they got programmed by edge connector? also if I remember correctly green boards are prototype and blue was production? maybe this is why they are not fully populated
