No they weren't broken, but when I was working on the underclock version I needed to sacrifice some options, because with to much options cgminer doesn't start at all (don't know why).
But if you need them I will put them back in for 3.1.

Here's hoping you hear from him soon!
I flashed the new Image on my 60 and 90 MH units, and for some reason they're getting a lot less hw errors. Not that I'm complaining, but what could have caused that? I was previously running version 2.0 on both.
I guess you were never able to get cgminer 4.9 working properly on the A2s? Also, did you ever figure a way of seeing the cgminer screen through ssh/putty?
I think it has to do with the updated stratum code having the miner run more smoothly. And no I can't get cgminer 4.9 get to work. And if you stop cgminer in the browser you can start cgminer in the terminal when you are logged into the pi, that way you can see the cgminer screen: sudo ./cgminer -o stratum+tcp://eu-01.miningrigrentals.com:3333 -u emdje.3166 -p x --A1Pll1 1300 --A1Pll2 1300 --A1Pll3 1300 --A1Pll4 1300 --A1Pll5 1300 --A1Pll6 1300 --diff 4096 --api-listen --api-network --cs 8 --stmcu 0 --hwreset --no-submit-stale --lowmem

Hi,
Do you think that investing in hardware now would make sense?
I am interested in mining but have no experience.
better not, it would make sense only if the price would rise so fast that the dif won't keep up with it, this will create a "profitability window" Only if you don't pay electricity  Turkmenistan citizins have free electricit, let's all emigrate Not anymore  http://centralasiaonline.com/en_GB/articles/caii/features/main/2013/10/31/feature-01 |

Thanks emdje, much appreciated. Sent you some beer money! Have you got your replacement chip back on the board? Thnx No I have not yet heard back from the person who offered his broken board (in return for underclock options, yet to be released). If I won't hear anything I might try to connect pins 13 and 14 and try the board then. |

Sweet, thanks for the updated cgminer emdje. Are you planning on releasing a new image with the latest updates? I suck at linux command line.
Sure I can. Will do that today. Edit: compressing image now, then uploading and posting the link |

Emdje, could you please compile new binary, where this parametere is 1min? Thanks
[2015-03-23 13:47:54] Pool 0 XXX stable for 5 mins

I will look at that BakSAj. Nice, I kindly ask only for cgminer binary, not the whole image :-) Rar file with the cgminer where the switching parameter has been set to 1 minute instead of 5, and the correct index file (made some mistakes in the previous versions with the difficulty setting and some obsolete options have been removed) Also all the stratum code of cgminer 4.9.1 has been implemented.: https://www.dropbox.com/s/f3t9eykuv1x2b1v/cgminer3.9.0-A2-v3.1.rar?dl=0Don't forget to mark the cgminer as an executable by using the command "chmod +x cgminer" |

I remembered having a kitchen hotplate lying around, so I used that to heat the board to 90 Degrees Celsius:  Then the hot air soldering gun was enough to remove the chip (albeit a little bit to soon, should have let it heat up a tiny bit more. Now you can see a little damage to one of the grounds on the chip base, but since it is the ground, and that is very large I think it will still work if it gets a new chip)   |

Preparing an underclock version, which so far only selects the 1000 Mhz/s as lowest, but I think I know what is going wrong (at work now so now time to work on it further).
And change to secondary pool will be set to 1 minute instead of 5 minutes.

Received my hot air soldering gun So I gave it a try to remove my burned A2 chip. At least I think it is burned and broken  :  But kudos to Innosilicon for the heat dissipation on the board. Even cranking up the heat to 600 degrees Celsius did nothing. The backplate spreads out the heat to fast  This is the first time I am trying this so I might be doing stuff wrong. If you have experience with resoldering and/or have some tips, please share. Backplate:  |

Not yet, but I might be getting a broken board from someone where I hopefully can salvage a chip from. I'll also try running it without chip (because the new A2's seems to have an open space). But I need to wait for the hot air soldering gun I ordered before I can try anything.

Thnx hrustix, Your log shows 2 sets of '12' chips. The cs2 one shows active cores on 10 chips. cs5 shows 9 active cores and then resets and shows 10 active chips as well. Haven't seen the new board yet, but would be interesting if there is an empty space there and one would solder chips on there |

Hello, I recently bought A2 new mini, and in stats it says, that the board has 12 chips, not 10, here's the pic:  Also, if you still want to finish your job with A2 new mini image, I want to help you in any possible way. Will try your 2.1 version within an hour, then reply. Yeah you are right. I recently found out the board seems to 'expect' 12 chips, but the logs only show 10 (at least the logs I received): [11d[M[25d [2015-02-25 03:58:52] Found chip 1 with 53 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 2 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 3 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 4 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 5 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 6 with 0 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 7 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 8 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 9 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 10 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 11 with 54 active cores
[11d[M[25d [2015-02-25 03:58:52] Found chip 12 with 0 active cores So I expect there is room for 12 chips but they only put 10 on it. Can you check your logs to see if the same goes for your miner? |

The only lyra2re mining software I have been able to find so far is for graphic cards.
Is there one for cpu mining I can experiment with for now.
How about my trying darkcoin?
There is also a Lyra2RE CPU miner that is already built. Works fine in windows 7: https://github.com/tpruvot/cpuminer-multi/releases |

Adding to it: the voltage modded board has been running stable for the past 4 weeks with on average 17 MH/s for the overvolted board.
