I wonder what Accel Partners got for their $15 million. I sure hope it was more thnn the 5 Neptunes pictured and some "magic beans". Looks like KNC has repeated, except this time they used folks with deeper pockets to keep their funding going. I guess the pre-order ~~customers~~ investors didn't pay well enough.

What a gigantic Cluster F**k.

Looks like they got the first 16nm chips in private mining operation.

Lie,
after one second check https://blockchain.info/pools

knc miner have 5% hash power, knc drop hash power 2% this year.
total world hash power is some last 6 month +5-7% https://bitcoinwisdom.com/bitcoin/difficulty

Can someone help me please, ive just noticed that my hashrate dropped a little bit so i have take a look at my knc miner and realise that some part of some cube seem not working. On the picture, we can see that dc/dc 0 and 1 on asic 2 are only at 1 W and same thing for dc/dc 2 and 3 on asic 3. What sould i do and why its like that ? Thank you

That's weird. Did you restart your rig?

Ive just reboot it and get the same thing :S...

Up the mhz on the low dies to 475, save and reboot. If they work, then you can start lowering the mhz.

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.

Had this same problem. Does the white light on the controller board flash 3 times about 30 seconds after power on? I had to downgrade mine to 1.15 to run all my cubes with this problem then upgrade to 2.00 without issue. Very strange these titans are have one cube that will only work on one of my controller boards and not the other no matter what port or data cable I try...

All else fails I'd try one cube at a time to try and isolate what the problem could be.

I'd hope the IPO investors did NOT have an open ended arrangement and KNC had to deliver the IPO data hall this year ie 2016...(it was announced last year) but knowing KNC they will
come out of this smelling like roses because NO such clause.....BUT on the other hand they are missing out (like a lot of us in 2015) on ALL that LOW (compared to 2015 vs 2016) difficulty
at least as compared to NOW vs 2016.....sucks don't it KNC all that mining you could be doing in 2016 and NO FRIGGING EQUIPMENT.....payback is a bitch!

yep ..see how it feels on a slow burn waiting for product....would not mind the 'paper cut' of them losing the class action to boot! (dare to dream)

Seeing as I haven't been keeping track of KNC for quite some time and since there seems to be a lawsuit in Sweden ongoing reading a few pages back in the thread, I think this block analysis might be interesting to some users.

Well could it have something to do with this also the BTC being pulled today from above guote/info...
....supposedly tape out on their 16nm chips was on feb 3rd 2015 o....they could be having some MAJOR issues ..AHEM or should I say 'pre-order' heh....
and needed the coin BADLY ...

Phoenix1969 pointed this link out to me:

http://wccftech.com/tsmcs-16nm-finfet-faces-delays-qualcomm-jumps-ship-samsung/

their press release back on tape out from main site www.kncminer.com

wikipedia on TWSC

http://en.wikipedia.org/wiki/TSMC

They could be very very very screwed in getting their IPO 16nm Farm out this year....serves them right IMHO......see how they like pre-order delays LOL

Anyway serve the greedy bastards right ....imho ...

Guess they shoulda put up that Titan scrypt miner farm instead don't ya know.....

anyway made my day!

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

Maybe it's the controller..

Exactly. The error message implies that the devices don't exist. Can you ssh into your machine and do a

Code:

ls -l /dev/i2c*

and confirm they are missing ?

I don't have any experience with the knc driver code in bfgminer but looking briefly at driver-knc.c, it looks like the i2c devices talk to the DC/DC converters.

BTW, are you sure you transcribed that error message correctly and it didn't actually say: 'Failed to open /dev/i2c-2 … ' instead of 'Could not open file /dev/i2c-2 ….' ?

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

Older .img's didn't help.

this probably won't help ..but anyway....if from the above the FIRMWARE did not take on the 2.00
I'd go back to 1.15 and try an adv page upgrade on a new SD card (sandisk 8gb class 10 i use)
using the original 1.15 firmware that is as the start point

if I'm off the mark on the above ..er nevermind....just tossing it out there as an alternative to flashing the SD to 2.00 with the img directions

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. Tongue

And do you get the same message on the console about /dev/i2c ?
