Ran v0.2 this afternoon for about 5 hours, worked great. Thanks for the update

m0mchil is the man.

Yeah switching to Eligius completely abolished this error. Something specific to ABCPool.

For what it's worth, I'm on Eligius and have not been seeing such errors.

That's not an error, really. It's just an announcement by the FPGA that it's found something that it thinks is a qualifying hash. For me, at least, every such announcement is followed by an "accepted" or "rejected" indicating whether the server agrees on the matter.

tf101,

do you mean 0.9A at 12v per fpga or per board?

I though each board would use nearly 20W at 200MH.

Regards.

Windows 7, Version 0.1.1, ABCPool:


Windows 7, Version 0.2, ABCPool:


Reject rate has definitely dropped dramatically with the new version. However, hashrate has actually dropped, I believe due to a a new error that I wasn't seeing before:


Maybe this has something to do with ABC Pool though? I'll try out a different pool. Also still getting lots of these "Golden nonce found" errors, not sure if they actually matter though?

Another user had this problem on Linux, and it turned out it was because he used the new D2XX drivers that came out on 12/23. I haven't had a chance to hack PyUSB to work with that, so please try it with 1.0.4 (download here). Please let us know if that works for you!

Version 0.2 is out!

The main changes in this are:

• Long-polling
• Progress line during bitstream pre-preprocessing
• And probably most importantly, fixed a bug in formatting data for share submission. Thanks to m0mchil for finding this! In my little bit of testing so far, this has reduced the number of rejects down to maybe 2%. I didn't want to wait to get this out, so please report the reject rates that you find in your own testing.

Download it from Github here.

Thanks again, m0mchil!!

Up and running in Windows 7 easily, not sure why I can't get it to run in OS X Lion. Even after downgrading to 2.6.7 and specifically specifying python2.6 it still stalls.

Looks like I'm getting some rejects/etc on ABCPool.co though:

What pool is everyone using?

I have found that forcing the getwork interval back to 20 secs (it's now default at 30 I believe), decreases my % of stales. Not sure if it applies to everyone, but you might wanna give it try.

I had that issue when I was first installing on linux... only way I fixed it was down grading to 2.6.7, when running python specifying the version (python2.6 ) and re-building PyUSB component.

After some fiddling, I got it to work on my Macbook. Installed Python 2.7.2 from the website (rather than Macports) and copied D2XX driver to the old version name that PyUSB seems to be looking for  "/usr/local/lib/libftd2xx.1.0.4.dylib".

Now, when I run python program.py fpgaminer_133mhz.bit

I get this:

But it just stalls at this point forever....

I'm pleased to report that I've located a second usable power supply in my apartment, and both my boards seem to finally be up and running.

On about half of the long-poll new blocks, I see errors like this:
For what it's worth, I'm using eligius - same as the devs.

Id just like to shout a thanks out to Fizzisist for his help over the last few days (some how I managed to blow a cct protection fuse on the molex connector to one of my boards). He has provided all the details needed and troubleshooting for repair, and offered repair free of charge (so great support). Currently mining on slushes pool with the following stats:

279.41 MH/s | 0: 1305/109/1 7.7% | 1: 1284/133/2 9.4% | 12h45m | AH00WOWE

and:

Each boards heat sink is at 37 degrees C, rear of board 49 Degrees C (ambient is 30 degrees C), and it is drawing 0.9A at 12v (inc an 80mm fan each).

Currently migrating the boards over to a dedicated mining micro PC (running a VIA 700 chipset and ubuntu), all powered off a ESP113 power supply (a HP 32A rated rack mount supply - details for them and using them for 12v supply can be found at http://www.rcgroups.com/forums/showthread.php?t=358340&highlight=hp+hot+swap+power+supply, the 5v 5A supply is the large middle pin on the bottom side).

There are a few stales in there, but I am looking at moving to a slightly smaller pool that I might have some better luck with... any suggestions? anyone tried bitminter with fpgas?

On a Mac, anyway to solve this?

google up some bitcoin profitability calculator, holmes.

My head's spinning and it's late.

All I'll say instead is that I'd love to see a profitability analysis on this assuming no electricity is being paid for, and then the same thing with electric at a USA rate with a laptop or netbook.

175 mh/s sounds awesome!!! can't wait.

My X6500 is out for delivery today! Yay! Testing tonight.
