Antminer S1 Stopped Working After Power Outage

[kbocek]

I have a new S1. Got it configured and it was happily mining for about eight hours until we had a power outage. Now when I restart the unit no mining is done. The controller is accessible, web and ssh.

My config is still there in /etc/config/cgminer.

When I fire up cgminer manually from the command line, it runs for about a minute. I can see my config being provided. But then it just exits. I can watch it running from 'top'.

I see the green mining lights flash momentarily on the mining boards but they do not stay lit.

/etc/config/cgminer:

Code:

config cgminer 'default'
        option chip_frequency '282'
        option miner_count '24'
        option api_allow 'W:127.0.0.1'
        option more_options '--quiet'
        option target '60'
        option overheat '70'
        option pool1url 'http://mining.eligius.st:8337'
        option pool1user '14vCRLHrHPbCCD5XNvoCdunr7pHpeFtMLN'
        option pool1pw 'xxxx'

Does anyone know what's going on? Like I said, this was working for a good eight hours.

What is the standard "chip_frequency" ? Did you modified anything ?

By the way, what type of coin you try to mine ?

Didn't touch /etc/config/asic-freq at all:

Code:

package 'cgminer'

config 'asic-freq' 'default'
        #option 'freq_value'    '4f81'  #400M
        #option 'chip_freq'     '400'
        #option 'timeout'       '35'

        option 'freq_value'     '4d81'  #350M
        option 'chip_freq'      '350'
        option 'timeout'        '40'

        #option 'freq_value'    '4c81'  #325M
        #option 'chip_freq'     '325'
        #option 'timeout'       '40'

Well go figure.

Yesterday, 'http://mining.eligius.st:8337' was working just fine. I swear. I mined for a good eight hours using that URL.

So I thougt I'd try the recommended URL, 'stratum+tcp://stratum.mining.eligius.st:3334' and sure enough, it works!

I swear I tried the second yesterday and it didn't work. But now that works and the first doesn't. Go figure.

Does the S1 do updates on it's own? Anyway, it's working now.
