there are many apps out there that will help you read the sd card from the pi, many times it is not possible to transfer directly from a full sd to a micro for the pi as much of the firmware also changes and if you simply copy and paste the files you wont have much success. but if you read the sd even from windows you can go into the folders and find out what make and model of cgminer is being used and that is more valuable then the sd card its self
So I used "Active Partition Recovery" to look at the folders on the hidden partition in windows. I was able to see the .cgminer folder in the root folder, but not access it (its just a placeholder/link or something).... I was able to look through the PHP in the var/www folder but not make sense of how it's controlling cgminer yet, or where its launching the app from (i learned C, not php)... so still kinda lost on that idea. but I do have the SD card... that's a big plus.
If you have any specifics on a utility that will do it better, I am all ears =)
holy shit those chinese really take "mining" down to the literal sense when they deploy these things.
What your looking at is the LKETC dragon miner
http://titanminer.com/?product=dragon-miner-litecoin-asic-30mhs-scypt-lketcIm 90% sure this was a partnership between zeus miner and LK group, so they most likely use a varient of the zeus chip/board. If thats so I developed a bfgminer version with some other guys for the zeus hashboards back in the day, and all you would need is a USB to serial adapter to run the boards with a PC.
Not sure why youd still run this thing though
That looks very similar to the one I have here, I would venture a guess that this is one of the very early LKETC ones. The hashboards have a single PCIE plug, and a "usb micro B" plug. The drivers do install and recognize on windows... so I am a little curious on why you think ill need to use some sort of USB->serial/TTL adaptor to talk to the hashboards.... The Pi did it through the USB ports before it's USB controller fried..
The web interface on it looks; very basic, and nothing like the screenshots in the link. Literally there's almost nothing displayed or to configure.....
Now the controller/pi fried because I hooked it up back in its original config to test more than one hashboard, and I had it hooked up the way it arrived, with no usb cable in the Pi's power port; Well, the back-feed of the pi drawing power through the USB chip from the internal hub was a bad thing and fried it... So I am seriously scratching my head at how the pi was powered as its mounting location left no room for a cable to get plugged into it's power port. My only guess is theres a dongle that's missing that went between the fan header and the pi's IO ports to power it. Still confused on that one.
Took the power supply apart; it's a 250v model (duh, it was in china....) so that explains the no power when I hooked it to the mains here in the US.
See; he has the ability to put it as a permanent install on a rack in a major corporate office (Think big like google, apple, yahoo, cisco, etc).... so power cost is not a factor. They are contracting me to build some rack mount GPU systems that will be installed as well. The network tech there gave him a whole rack to utilize in his building.... not a small thing to ignore =) I gotta stay silent on what corporate place it is; but knowing them, Ill have to make all the devices on the rack connect to a unit that will act as a server; being a VPN link to my home network for all the miners. This way I can access them from the outside world and update if necessary. Ill also be making an S7 he has rack-mounted.
Being stuck to only coming on an odd saturday to update them in person is too much of a hassle when it comes to security and whatnot. Our only issue will be hard-boots. I can deal with that, as Ill email him and say "go reboot machine x". MY only concern is the S7... it was very finicky when I hosted it at my home for a year..... solo mining on ck it was solid; but when on zpool, it kept getting odd disconnects. IDK if that problem still persists.
