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.
Topic: Ultra Under-overclock image for A2 Innosilicon by Emdje - V5.0 - page 15. (Read 79746 times)
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 
So I gave it a try to remove my burned A2 chip. At least I think it is burned and broken I don't know, looks like that might buff right out?
Good luck!!
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.

Emdje, could you please compile new binary, where this parametere is 1min? Thanks

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.
emdje, did you end up fixing your broken board?
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

I can for sure, just tell me how to do this, I'm not very familiar with linux.
PS: tried your 2.1 image, cgminer didn't start.

Ssh into the PI and follow this tutorial: http://www.penguintutor.com/news/raspberrypi/linux-static
For Ssh follow this: https://learn.adafruit.com/adafruits-raspberry-pi-lesson-6-using-ssh/ssh-under-windows
Then open the file explorer and navigate to the /var/www. Right click the cgminer.log and open with leafpad. Select and copy the text until you see a couple of lines of accepted hashes and post is here.
Any questions? Just ask

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):Also, if you still want to finish your job with A2 new mini image, I want to help you in any possible way.

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?

FYI,

the above works for Extranonce support on miningrigrentals if you add it to the local config on the A2. So far its been working good, thanks again emodje!

Sorry, but as soon as I do that I will get a lot more questions about stuff not working. The image works. You would just need one downtime and than copy the executable on a USB stick for the rest of your miners.
February 12, 2015, 06:05:09 PM
Any chance of just getting the cgminer executable w/ Extranonce support so i can upload to my image. I don't want a bunch of down time just to swap the cgminer executable. Thanks

Found the error, soldering error. But when I tested the board, I f*cked up the cooling and fried one of the chips 
I did however fix the issue, but now it doesn't work any more.
So either I need to get a new chip to put on the board, or I take it off completely and solder some wires on it so the daisy chain is good again.
(IF ANYONE HAS A BROKEN BLADE AND WOULD LIKE TO DONATE THAT TO ME, OR LOOSE CHIP(S), PLEASE LET ME KNOW)
