Cairnsmore1 - Quad XC6SLX150 Board

[Doff]

The dip switch settings were posted a page or two back by Yohan. I believe Switch3 needs to be off, all other on, to program. For "normal operation" it's ALL switches in the "ON" position.

As for that error, I hadn't seen that error on mine. It sounds like a baudrate isn't being specified. If it isn't defaulting one, use 57600 for it, that's the rate this bitstream talks at.

Check that and let me know. If that still causes an error, take a screenshot of exactly what the web UI looks like when you get the error (ie: what stage of the UI this error gets thrown, upon clicking new worker, when filling in the form, when saving the worker, or whatever).

I figured it out the switch settings by accident, I also got MPBm working by creating a normal Icarus miner and changing the Baud rate to 57600. I get that error for the cainsmore the moment I click create new worker and select Cairnsmore from the drop down menu. I have 3 of 4 FPGA hashing away at about 180 it says.

I can give you a screenshot however everything runs perfectly in MPBM except creating that one miner type from the dropdown like i said so im not sure how much it will help, but ill post it in a few here anyhow.

Im getting the same exact results with cgminer an glasswalkers bitstream. I suppose this is the point where I  need to learn how to compile crainsmoreworker... there isnt a windows build out there, right ?

[rampone]

okay, loading makomk 140 bitstream: no success, only f#1 doing sth, but not reaching cgm or mpbm

now trying to load into flash first...

what about the idea of grabbing an irc channel? #cm1 #cairnsmore #enterpoint or sth?

#cm1 up on freenode

sure? ebereon and me are there

I'm fairly certain Baud rate needs to be changed somehow in Cgminer to make the Glasswalker Bitstream work in Cgminer I know there are a couple files you can change to do it If Kano is still reading maybe he can give us a tip.

I'm getting 500 ave mhash in MPBM with glasshwalkers bitstream, and 1 of the FPGA's doesn't work which I think is a known problem.

[LazyOtto]

The problem I had with mbpm is that the wep-interface used to configure it is distorted for me. I cant for example even push the button for worksourdes,

The mpbm web interface does not play nice with Firefox. (I.e., doesn't work worth a damn.) This is a known problem.

Try it with a different browser.
For me, works fine with Safari.

Chrome also works.

Glad to hear you guys are getting positive results!

Can you post a screenshot of your miners in MPBM?

Also is MPBM reporting hashrate correctly? (I hoped I had fixed that but have yet to test it). If it is that's awesome.

Well so far so good!

I've just finished the rewrite of the UART code, it should solve the 4th slot problem (I hope). This build will be 150Mhash, but it's better than an idle chip. (so flash the 175 on the 3 that work, and on the 4th flash the 150).

It's still synthesizing and could be up to 24h for me to close timing on this one, but I hope it will be quick.

This one also has several more improvements. So once this is working, and tested. I'll hit it headon with all my compute power to optimize and push for a higher timing (as high a hash rate as I can get out of it).

We're getting closer!

EDIT:

Also those of you who have it working, can you post your board serial numbers with success? I hear from Enterpoint that boards under ~50 will possibly have more issues than the higher number ones. My dev board at home is #1 so it's the "worst case", but would be good to know if all of you so far are in 50+ boards, or if anyone is having success with an early board.

Thanks!

Got Glasswalker's test bitstream programmed and working.

Took my most stable board (2.63 + 2.63U with twin-test), programmed to SPI and seems to work. After ~25 minutes I get:

As Glasswalker mentioned, one FPGA is idling (orange LED lit), but 7.5U is way better than 5.3U

For programming the DIP switches are to be set as Yohan was explaining in the post here, while for mining the mini-howto is almost complete: you need to switch all FPGA DIP switches (2-5) ON.


For those working with Linux, I am using the xc3sprog toolsuite natively, built from SVN with the patch I posted here and the following script (ran as sudo):

Code:

#!/bin/bash

BS=fpgaminer_top.bit

./xc3sprog -c cm1 -p0 -Ixc6lx150.bit $BS && \
./xc3sprog -c cm1 -p1 -Ixc6lx150.bit $BS && \
./xc3sprog -c cm1 -p2 -Ixc6lx150.bit $BS && \
./xc3sprog -c cm1 -p3 -Ixc6lx150.bit $BS && \
    echo "Fertig" | zenity --info || { echo "Fatal error!" && echo "Fehler" | zenity --error; }

You'll need to build cgminer from source with the Baudrate set to 57.6k to mine.


Edit: copy-paste garbage fixed

What do you have in the serial port field when creating new workers?

This error means it can't open the serial port. Are you in windows? if so you need to specify the port as COMX (ie COM1 COM5 COM23) without any leading slashes and such like cgminer.

If you are in linux it should be /dev/ttyUSBx

Try that and let me know if it helps.

How do I set the Baudrate in Cgminer Zefir? I have 2.5.0 built already just need to set that Baudrate and I think I'm good.

For Glasswalker's bitstream and his MPBM worker you need to change the following lines to get the correct MH/s in the Webinterface:

cairnsmoreworker.py:

Code:

          # Calculate the hash rate based on the processing time and number of neccessary MHashes.
          # This assumes that the device processes all nonces (starting at zero) sequentially.
          self.stats.mhps = nonceval / 500000. / delta

          # Calculate the hash rate based on the processing time and number of neccessary MHashes.

That was in controller rev. 1.0 i think or 1.1 and shipping_test bitstream, but glasswalkers bitstream needs a complete different controller rev. with much changes in the dip settings. I don't think there is a dip that change it.
