The first log reports that 'Run Reset' as well as 'ST MCU' and 'GPIO CS' are all disabled, which is very weird. That is the reason you aren't hashing in the first log, because they all should be enabled.
In the second log you don't report the first bit, so I can't say anything about that.

Did you use the complete image? Or did you only copy the new cgminer?

Where is cgminer started from?

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

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.

Just burning another copy isn't an option. I need this to be reliable as it will left unattended for some months soon. It seems other people are have the same problem. I won't be able to burn new firmware every weeks once I'm away. I'd like to fix it properly, give me some clues where to look and I'll have a go. Otherwise, it's keeping the glitchy Minereu firmware but with your cgminer for now. Minereu does drop boards randomly, without reliable firmware, I'll probably just sell the thing as profitability is getting tight now.

I don't know where cgminer is invoked, what invokes that etc, reading every file for clues gets tedious fast.

It took me weeks to work out where to modify the Minera web interface on my gridseeds to underclock below 600MHz, hacking cpuminer was the easy bit. My gridseed blades are now rock solid and hashing away at 7J/MH. I'm trying to get the A2 to similar efficiency and reliability or it's getting sold, I have about 3 weeks to do this, and not that much time. Not enough time to read every file to work out how your firmware works.

If you look closely on the blades you will see LED's that are marked LED_UA4 - LED_UA3 ...... to LED_UB1. These LED's indicate if the chip is properly working. When blinking they are noticed by the software but not running yet, when they are not blinking they are hashing and when they are off there not working.

I've had a  rummage, your image is infinitely simpler than minereu or even scripta, whoopsie.

I've set it to append logs to cgminer.log so it does more than one session and had a nose around.

If it can't connect to servers on starting, cgminer exits. It doesn't seem to retry, at least not very often. this is not good for those of us with flaky internet, is there no watchdog? I can't find one, but may be looking in the wrong place. I thought there was a swiitch to stop cgminer exiting, but can't find it, maybe it's just cpuminer. I wrote a crude watchdog for my rigs two years back, I should be able to find it, somewhere. I haven't got it to duplicate the no A2 miners found error today.

I'm currently cloning minera to see if I can get that to play ball, I have it running sweetly on my gridseed blades. It might be worth you collaborating with Michelle if I fail. I tried to get cgminer to run on my gridseeds last year, but failed.

log from this morning, while both connections was down (it's fun out here in the sticks). It exited repeatedly the same way a weekish back when it did have a live connection, possibly servers were sluggish? Both main and secondary connections pinged ok to google DNS that time. My other rigs were showing as hashing on the pool site. The only thing I've done to your image since last week is change '> cgminer.log' to '>> cgminer.log' in index.php and run.sh it's running now...

Great to hear that it is working again! But where did you buy these broken blades?

I can't find a watchdog, no sign of cgminer getting restarted.

I've got my own watchdog running now.
Other than stopping, possibly when trying to start when servers aren't responding quickly enough, your image has worked ok.

I had a quick go at putting your cgminer in minera. It didn't seem to like the mix of command line and json.conf. I can't be bothered to delve into minera...
