In-between errors there are several successful processes. It's chronological but far from complete. I don't have a way to capture the video off the hdmi ready atm.

If it's a file-system error I can't see why fresh installations of .img files wouldn't t fix it.    Maybe it's the controller..

Yes I do unfortunately.

I don't know how to advance from here. If anyone has encountered the /dev/i2c error or thinks they know the issue pm me.

My only ideas are to try yet another sd card, change data cables, or ... contact KnC who will probably ask me to send a sealed envelope with $1000 inside.

Yeah, I've flashed 2.0 on 3 different sd cards to no avail.

Older .img's didn't help.

Good Call.

I tried that and everything booted for the most part until (paraphrasing)

[Warn] Kernel Lacks cgroups or memory controller not available, not starting cgroups (warning)

Error opening dev/input/event ......

and then more things succeeded in booting until finally I got one error which repeated in perpetuity:

asic 1-6 die 1-4 " "

Error: Could not open file dev/i2c-2 or dev/i2c/2 no such file or directory.

It continues saying that until it reboots. 

Anybody know what that means?

Pools are live and I'm about out of ideas. That purple light doesn't seem to be coming back.

Has anybody noticed the flat ribbon cables have letters engraved on them? And they're different for me.

E E Q A F

I wonder what that means, it has to be something otherwise the manufacturer wouldn't take the time to etch it. Probably not important.


Anyways, has anybody had success getting Titans to run on anything other than the KNC issued controller?

Unfortunately bfgminer runs at 0 mh/s with none of the cubes recognized.
Sometimes it shows every slot as OFF othertimes the entire cube on/off interface doesn't show up.


It used to detect all of the cubes upon start up and then the pi screen would display info. Now I get one lone green light and nothing happens.


The only things I can imagine is the controller is damaged or the cords are damaged or it's a software issue.

I'd really enjoy a 'detect hardware' button on the KnCMiner interface.  

Does anybody have a configuration backup that is recognizing cubes? I don't know what that file stores exactly.

I'm having a problem with my Titan that I can't resolve.

After a long period of successful hashing I unplugged the cords and moved my cubes.

After re-assembling everything no cubes are recognized. I can see the knc web interface but no cubes and a blank pi screen.

Yes the cords are seated properly on all pins. I'm running 2.0 but have tried several revisions on different sd cards.


Has anybody had this happen (No Cubes being found) and if so how did you solve it?
