If you have a spare card I would burn a new one and try it with that.
Cgminer is started from the /var/www folder

About your log, your second log should start like the first one you posted.

Hope it helps

what program starts cgminer? I'll try and work backwards and add more logging to find out what is going on

only blue light and one light on side of plate on top of blade.

about logs. tried your image but wasnt lucky.

on image that was installed was reporting no device.

I get NO DEVICE RUNNING
any idea why? is my A2 broken?
got it today:(

Could you post the logs?

If you don't know how: First ssh into the miner: https://www.youtube.com/watch?v=L4iyDFsepxI
second: open the file explorer, than navigate to the /var/www folder and open copy the cgminer.log

And, are the lights on the blade blinking when you start the machine? Or are they burning continiously?

Where is cgminer started from?

Complete image. The 2nd log is /var/www/cgminer.log I think I got it all. I can't see what errors it produces when it autostarts, but the manual start produces both no boards and no pools errors.
Do you want anything else, or shall I burn a fresh copy? I'm likely to be leaving it unattended for a several months soon soon, so I'd like to find out what broke and how not to have it break again. Minereu is working atm, but it has that annoying habit of occasionally dropping boards. It's web interface is funny about starting too.

I'm using Transcend 8gb ultimate cards, which I've found to be extremely reliable (got 4 in pi mining rigs, not had any die or glitch on me). Pity they seem to have stopped making them...

I downloaded the latest underclocking version a few weeks back. It ran fine for a while, yesterday, it stopped. It tries to start, but exits. Sometimes it reports no A2 boards, other times, it reports no pools, and exits. /var/www/cgminer.log below 5 boards is correct, I'm pulling 1 at a time to underclock some more. I can copy cgminer into my minereu firmware card for now, but that had an annoying habit of dropping boards, which emdje firmware doesn't. I'm using same servers with minereu firmware, which runs ok. I can pull more logs if you tell me where to look. Starting manually doesn't work either. I used

sudo /var/www/cgminer -o stratum+tcp://eu-01.miningrigrentals.com:3333#xnsub -u pictsidhe.10165 -p x -o stratum+tcp://us-central01.miningrigrentals.com:3333#xnsub -u pictsidhe.10165 -p x -o stratum+tcp://us-west01.miningrigrentals.com:3333#xnsub -u pictsidhe.10165 -p x --A1Pll1 1000 --A1Pll2 1000 --A1Pll3 1100 --A1Pll4 1100 --A1Pll5 1100 --A1Pll6 1100

and sometimes it starts but can't find pools then exits, other times it finds no boards:

let me know if you need other logs, Emdje firmware is on a spare sd card so it's sitting around.

Are these new images compatible with the A2 Mega? Or is everyone overclocking the original 88 MH/s A2's? 
Unfortunately the A2 Mega uses a different board design which is not compatible with this image. I tried several times to make it work with the new A2's but I don't own one so it is very hard to try stuff out.

It's mainly a hobby for me as well.

Unrelated, the Raspberry Pi in mine let out the magic smoke, and none of the local distributors had any of the "original" RPIs in stock, so I ordered a Raspberry Pi 2.  I've modified the mounting plate to fit it and bent two of the GPIO pins back to accommodate the cable the miner uses, and it powers on, boots, etc., but doesn't seem to be able to talk to the blades.  I'll get the actual error and post it here, but it's complaining of something along the lines of "Unable to set CS pin 0x4...".  The first twenty-six GPIO pins are the same, so that's not the issue.  Any idea what's going on?

Try installing the new bcm 2835 library. Probably the one I installed on the image is not compatible with the PI 2 : http://www.airspayce.com/mikem/bcm2835/index.html

$234 for six plus an extra ~$130 to see it in less than a couple of months is almost as much as I paid for the miner itself.

Heat sink is already here, and was 30 bucks for 2, so doable. And hey it's just a hobby, just looking how much I can change the thing. You guys might get some good info out of it. And it keeps me of the streets  Tongue

With firmware 3 is no such problem.
So prolema still in firmware instead of 4 in the pool.

Weird because I use version 4 as well and have no issues with it.

Can you post the logs, so I can take a look? Pretty hard to find the problem if I can't recreate it.


Yeah, same problem here. Sometimes when pool 0 goes off, cgminer stops mining with "no work available from pools" message. Didnt see this in earlier versions (with old stratum code). But I noticed this behaviour only with pool 0 = BetaRigs, pool 1 = mining rig rentals.

Btw, do you guys use any cgminer watcher? Since Im (from the beginning) loosing e.g. one blade in 14 days and then I need to restart manually.

Hmm two people with the same issue. Will look into it when I get back from my holliday. Most likely put in the old stratum code.

so if i want to get more hz (let's say the default is 1200, i want 1300-1350) all i have to do is to buy a stronger PSU?
the current one is 850w gold.

I would measure what the PSU draws right now. Overclock one blade, measure again and calculate if your PSU can handle it. PSU's are most effective when used intensively (but not over their limit of course). If it is not enough than you can buy another one. Or use an extra smaller one for one or two blades.
