Doc, Recently i found a block but cgminer did not report it. I have found blocks before with getwork and i was able to see Found block count > 0 matching the actual found blocks reported buy bitminter I am curious how do you check valid shares when diff >1? What i mean is this: According to my understanding it works like the following: 1. Mining software knows that it shall shall submit work only if its matching difficulty (let say 4). 2. Mining software shall check if valid shares which are less that required difficulty solve the block 3. If yes they shall be submitted to the pool even though they are not matching pool difficulty 4. Pool shall check first (or at least before diff match ) if the share submitted solves the block and later on if it matches difficulty right? What i am asking is are any potential issues from both miner and pool if a share solving the block can be rejected by the pool or not sent by software? I am just curious:) 10X PS: just for the record i wanna check why cgminer does not report solved block. If you do keep log of share solving the blocks and you can paste here the winning share for block http://bitminter.com/block/btc/0000000000000201264143a1bca71fc300d02bf0a3e0d8cd85a407024abd7129will be great 10X |

Hello,
There might be potential Found block bug in cgminer 2.10.5. I had found about 5-10 blocks since i start mining. With old versions of cgminer (getwork) I was always able to see Found Blocks count > 0 from the cgminer api. Recently i Found a block and my pools says that is me who found it. But cgminer shows 0 under Found blocks menu. My question is follows: When mining with stratum and diff > 1 let say 8, is there any chance cgminer not to report to pool that block is found. In general what happens when we found a block, and our share matches to diff 1 which does not meet pool requirement for diff 4 for instance? Is there any chance found block to be wasted and never reported to the pool?

dude, they're all guilty of it. Avalon "SHIPPED" 4.5 weeks ago! Only 2 (maybe 3?) still delivered. bASIC? pre-order and fall over. I'd shut the fuck up if I were you, NOT ONE company has delivered mass ASIC yet. NOT BLOODY ANY ONE OF EM!! Dude, I am not going to argue with you:) But if i were BFL customer and there is no single proof that chips are OK i will be concerned. There are already passed 10 days or so and there is no single proof that chips are ok:). Prove the opposite if i am wrong. Just to refresh your memory - for that amount of time (10 days after receiving the chips) Avalon team made Working unit with cgminer and shipped it to Jef:) Do you remember that fact??? So Pray to good that chips are ok. Then pray to good that after some time BFL will start to ship:) |

Hello ,
Can you check what dmseg is saying about flash size and post the results.
On my tp-link host used with Lancelots with 8Mb flash it says
dmesg
-------------------------------------
[ 0.730000] ath79-spi ath79-spi: master is unqueued, this is deprecated
[ 0.740000] m25p80 spi0.0: found s25fl064k, expected m25p80
[ 0.740000] m25p80 spi0.0: s25fl064k (8192 Kbytes)
I am curious because i am planning to build own image with some more applications (php, openvpn, 3g support and so on) and i am not quite sure if 4M will be enough. I will disable wireless drivers/apps whch is going to give me some free space but...it might be not enough
10X
openwrt rev r35097. [ 0.480000] m25p80 spi0.0: found en25q32b, expected m25p80 [ 0.480000] m25p80 spi0.0: en25q32b (4096 Kbytes) this kind of flash can be found in newer revision of wr703n / wr720n. You may not success I think. including openvpn may eat a lot of space. just for cgminer, if you can build a libcurl without openssl maybe there is chance. you should use a router instead. remove the ppp support should free some space to allow updating cgminer to jffs2. Thank you very much! Or i can buy Wr-842N hack it with 64M Ram as i did already and forget about it:) Wish you luck with your Avalon:) Best |

Sorry, no increasing. may have hurt normal shares & rolled back. seems not touching that number yield better results. I think 43-44 do not worth testing because the change should be minimal.
Thanks! One final question. I know that your shipment was a domestic one. were there any invoice or documents with your order? If there were am particularity interested what was written inside - especially how avalon unit was named? Something like PC. PC parts or whatever? There was taobao transaction history but the item is now pulled off (not for sale long ago) by ngzhang. there is only a snapshot that I can get. payment is done via alipay. on Chinese bitcoin related forums, it is called "阿瓦隆矿机" (Avalon Miner) or "南瓜矿机" (literally pumpkin miner, pumpkin is nan2gua1 in pinyin, which is first 2 character of ngzhang's nickname) --- (checking the box) Ah~~~~!!! I found it! "控制箱" (control box) on the delivery receipt! the outer box is a typical unprinted big one, no printed pic/text. I guess ngzhang would come up with many names to let your package pass  I guess so:) Thank You! Best |

Overclocked Avalon?
Magnificent.
Water cool that suxor!
Mineral Oil - Transformer oil in my case to safe some bugs:) ate least that is what i am going to do if i need to. As long as capacitors are on top of the PCB precisely one can sunk avalon board and leave the capacitors dry - that will be best solution from my point of view:) Oh yeah and when pcb is oil cooled stock heat sinks will be removed (or sealed) for sure to avoid air pockets:) |

3 HW Error about 0.55% ~ 0.65% @ 282. ~0.75% @ overclocking to 300. hashrate increase by 5% if overclocked.
Dude, The review is just great! Please, can you confirm what options are you using for overclocking --avalon-options 115200:24:10:45:300? Particularity i am interested in time-out value --avalon-options 115200:24:10: 40-45??:300. Have you tried with something smaller than 45 (default) Best I'll try 42:300 soon. Great! I am very curious if that will increase the hash rate a little bit more:) Best |

https://github.com/ngzhangIt is more advanced than doit yourself but there is a lot of useful info - schematics, components, bitstream source. Good luck:)

It seems strange to me that they don't have a working product. Making a large order and just hoping that everything works out seems risky. I don't see how they can be so sure everything will work correctly.
This is a new age....throw tons of money at a business that has no working product for months....just have "FAITH" I'm only worried about mass producing something before testing it. I agree here. Testing should be done on small quantities (i.e. a prototype ...DUH). BFL must have some magic potion that allows them to divert the normal development process in any new technology. Unicorns, leprechauns, pots of golds, lucky charms, rainbows! You remember that little fiasco where they were using a QFN chip, but then when they tested it, the plastic couldn't conduct the heat out of the chip and into the heatsink? Well, lets just think about that for a second. They had chips, and they were even testing the chips on one of their boards. If they really had a faulty design, and the chips really couldn't hash, then they would have known about it in October. They would have known that is more easy to change pcb and heat sink instead right? Sounds logical not to throw away the WORKING CHIPS with the money paid to produce them? And miss the chance to show a working video of "overheating chips" just for a seconds to suck Avalon and BTCFPGA potential customers - roughly about 2+ million USD. I doubt that they are so damn stupid to miss that chance what about you? But yeah it sounds more logical compared to TOM famous excuse of powers of two for those that remember that ridiculous post. The most funny thing is that particular post brought to Tom/BTCFPGA more orders I can say that BFL learned a lesson and are doing good compared to to tom. But we as a community are not learning unfortunately |

You realize the difference between a company selling shares of itself, and a company that is running a securities exchange? The former could be a medium size lawn care service or computer shop for example, and might hire a lawyer and an accountant for a few hours each year, while the latter would need to be run by lawyers and bankers.
Its actually issuing shares and selling them to the public which is most illegal. The mechanism is irrelevant. Exchanges are subject to regulation, but that's not really why GLBSE was shut down. Selling securities to just one person in the USA means you must register with the SEC. I would say thats the typical US-Attitude of "We own the world." Nothing will happen when a US-Customer is buying shares in china. Or did you hear of plans for the next military intervention taking place in china? China has enough USD to make the US die, so no, nothing will happen here because of a bitcoin business. Most people doesnt even know what bitcoins are. Thats fetched way too far. Its true that a company that was at an american stock exchange cant go out of it when only one single us-citizen owns a share from them but how will you prevent that someone is buying a share in china? Maybe i sell a share to an us-citizen. Is bitfountain forced to register with the sec in the us then? Not really. Actually China owns both EU and US. they can buy and sell our ass as many times as they want:) And that is only our fault there is no one to blame. Back to the topic Speaking of US-Attitude of "We own the world." they can not even make TOM/BTCFPGA refund their money even though he is American and they are Americans also. Where is American Law and justice - nowhere it is just not working or? Guy's all you need to do is to grow up it is about time...Just think and act like adults and face the facts and think think and think |

I changed maximum worker difficulty from 64 to 4096. There are some crazy fast miners around these days.
Let me know if there are any issues.
Doc, A word how you calculate difficulty based on miner speeds will be great:) let say i have about 100 000 Mhps what difficulty shall i have? |

That is what the machine does during boot: run cgminer from the command line. That is necessarily how it must be run under Linux One only needs to edit /etc/rc.d/S99cgminer. Here is a sample of S99cgminer: DEVS=`find /dev/ -type c -name "ttyUSB*" | sed 's/^/-S/' | sed ':a;N;$!ba;s/\n/ /g'`
PARAMS=" $DEVS $POOL1 $POOL2 $POOL3 --avalon-options 115200:24:10:45:282 -q --api-allow "W:0/0" --api-listen "
ntpd -d -n -q -N -p 0.openwrt.pool.ntp.org \
-p 1.openwrt.pool.ntp.org -p 2.openwrt.pool.ntp.org -p 3.openwrt.pool.ntp.org && \
start-stop-daemon -S -x $APP -p $PID_FILE -m -b -- $PARAMS
jeff, Can you try --avalon-options 115200:24:10: 42:300 Or something similar just to see if there is real increase in performance and post here the results? 10X |

Probably we will get mails from avalon when our transactions are confirmed after six blocks?

They NEED your money to assemble batch #1.
Go give your hard earned to the Chinese but do not expect anything (except a headache) from them in return!
BFL is a revolving door. Early adopters get out after waiting so many months with their money out of their pocket. They give out refunds quickly and expediently because: New customers fill their pockets with even more cash and end up replacing the older customers. If the chips don't meet specs then, everyone runs out the door at the exact same  time and you have a bASIC situation all over again. (Well, unless you have a large influx of new "customers" at least.) And when BFL BTC customer gets refund right now he loses 90% of his initial investment right? It is very clean way to make money:) And that is the reason no one wants a refund at least from BTC BFL orders. Go on order order BFL is eager to get your BTC:) |

This is nuts. Without confirmation that Batch 1 Avalons are in the hands of miners purchasing from batch 2 is quite a risk. Throw in the chance that BFL might ship and this is plain gambling.
Lol. There's more gamblers than investors here.... Throw in the chance that BFL might ship and if you order today most likely you will get something next year is the safest bet. So go on please make BFL orders right now because you need to have your order in the queue  |
