Yes I understand now. I checked all the connections and just turn the miner on Now none of the cubes are working hihih I can't believe That anyone can build such a device with mind of it is on

anymore ideas ?


There is a small button on the controller do you know what it is for

No white light but I've got green light and no screen

It VERY much sounds like controller is dead. Ive had the same thing happen. In my case it was not the bridge or pi because I took a known good bridge and pi from another controller  and plugged that into my faulty controller and got the same result and that was a :

1. Power with blank white led screen
2. 1 green led controller

=

Dead controller.

The cheapest fix is to use a controller from a neptune. I beleive this is confrimed that the neptune controllers DO work with our pi and bridges. I dont know if more needs to be done or not. I believe neptune controllers can be found cheaper than Titan controllers on EBay.

I have your exact same problem. If I get time, I will diag mine. It could be one of the surface mount capacitors. I have a capacitor wizard that can test "in circuit" capcacitors and resistors. If I can get it working, Ill post how.

I have a rasberry pi2 . No go on titan controller. Tried it. Nothing bad happend. Just didnt work. Are the bare neptune controllers IDENTICAL to the titans? Can the neptunes accept a rasberry pi2?


I bought one and the other is yours:

Yeah I got mine from that guy. 2nd feedback down.

I got a Saturn Controller 4 port (with the small 2 ribbons) I can let go for 100 bucks plus shipping. If you want to try a working bridge on such. Also hawkfish007 on here has
2 clone bridges for sale for what he has in them for 0.5 btc ..same clone bridges from Qberty's run of 10 boards. The controllers he got them for did not need the bridge fix. So
last I heard he had extras to sell  at his buy price.

Anyway options for folk looking thru this thread for options above and beyond a full blown titan controller purchase off ebay or whatever.

As to my Neptune Hack it went flawlessly.

So sat down with some nerves....slowly removed the BBB from Neptune controller ..a slow wiggle back and forth took 5 min ...tight ...also had to very slightly reshape/bend some pins back vertical ...not much thou..then (not sure if correct to do this 1st) put the NEW (spare from back in the day) 35 buck Raspberry Pi 512mb B+ (all ports matched titan check) and put it on the daughter board 1st very easy to do...the slowly worked the pi/clone bridge works on to the Neptune board ...slightly tweaking ...very little needed but slightly some pins made more vertical. Did a quick recheck.

Then pushed the whole works on....all looked good....made my KNC img 2.00 Sandisk 8gb Class 10 microSD pop'd it on..I left the Neptune LCD on powered it up w/o cubes and viola LCD said "my creation lives" ie a Titan KNC 2.00 came up on the LCD ...at that point I put on my 1 cube with 1 working die (overclocked at 325 dare to dream) and closed eyes and turned it on and viola no boom ...a merge from knc minion to evil knc minion so to speak

chugs along at like 21.5mh or some such (well it is the only die in the unit ..seems to like the OC to 325 on adv page and ..cooling is likely not an issue as it is the ONLY die to cool)

here is a link to my complete setup

here is the pic




Again if you have an electronics guy that can trace the titan bridge...add a much bigger version of the micro sized clock chip on the daughter board...get a protoype board for the pi
some single end pin'd wires for such and spaghetti it all together to match the pin outs on the titan bridge with the equiv LARGER clock chip in place on a line or two proper as well and the whole thing could probably be hacked together at no more then 50 bucks.

Toss that info schematics and parts into the Titan world for free if you or anyone else here has the skills to do so ...you'd be a god on this thread



I lack the skills with the clock chip in play...but for others with electronics skills should be a snap...at least from my layman view.


but with Qberty's 0.5 BTC clone bridge...you just snap it together and viola it comes up....so I would assume ANY working Titan bridge would work for this. (how to test such
a bridge w/o putting the port board and LCD at risk I've no clue..just saying...but hey life is a risk)

and again this could be very very handy for those who KNOW or suspect the titan bridge is fine.....and thus grab a pi an old knc board 4/6 Neptune for sure I've been told 4/6 port Mercury/Saturn/Jupiter boards work  as well ( i have 2 such but alas no more clone bridges...thus my hope for a skilled spaghetti hack as I mentioned above)

anyway was a nice hack for a titan bridge I got for 75 bucks insurance (that is per my 2 titans)  in the box (with the pi) as a just in case for my 2 titans having a future
common bridge problem.. so it worked out well for me being paranoid (it again is knc evil don't ya know)

but anyway I got cards 4 port for 100 bucks the Neptune card from the guy above is 149 bucks ..you just need a titan bridge board you know works or a Qberty clone titan bridge
from one of the 7 who got one (qberty kept 3 for his fixes from what I understand)

but 0.5 btc now 2 months later imho is too steep a price and I think he was selling them at cost to make in lots of 10....so if you need one get a hold of hawkfish007 he has the only 2 clone titan bridges left that I know about.

As always you don't like my rants/ramblings put me on ignore. (the curse of typing as fast as you think)

The only incompatibly I remember on controllers was something about NOV Jupiter Controllers running OCT Jupiter/Saturn/Mercury cubes or vice versa. That is moot

as soon as you move into Neptune stuff as far as I can remember. (Others with NOV Jupiter Units chime in here)

You can ask Lightfoot but I don't think there is any issue with incompatibility on the Neptune and Titan front except between them. With their respective groups Neptune
and Titan is all good. Also from what I understand ANY port card works with anything else. ie you can flash now any Jupiter Board with a BBB to a Neptune Controller with
just the SD upgrade to the Neptune Firmware.

Some people tried Pi2 only thing that works is the Raspberry Pi B+ 512mb with the proper ports that match...(not sure may be another version) some say they have 'tweaked'
the speed of the regular pi b+ 512mb thou I never have.

KNC lied back in the day...said that 2.00 firmware was ROBUST and complete. (That should put Gen Tarkin on the floor).

No way to repair cubes  ....ie your screwed toss them.....(lLightfoot can get into the ins and outs of that statement)

My likely theory is when KNC took out the Jupiter's from the Data Hall and replaced them (thus the 4 months late) with the pre-order paid $$$ Neptune's they took first and

thus screwing the pre-order Neptune folk by 3-4 months arrival.

They took the 4/6 port controllers and used them from the Jupiter data hall (hell likely they were all 6 port by the time the data hall was up for Jupiters) and we know they used them with the

used FrankenJupiter junk equip they sent out. ...so IMHO they used these boards for Neptune and Titan customers...but lied that such was possible (at least to me)

on KNC forums ...(others from then can chime in here). I especially was told no way could you plug a bridge/pi into the 4/6 port boards of a Jupiter for either a Neptune or a Titan (even with a bridge and a pi).......so supposedly you could not switch ANYTHING between groups of product ..I think this died as a lie when the frankenjupiter's folks junk arrived in parts
and in desperation they flashed some Jupiter boards that worked to hamstring them up...but again others with actual first hand experience can chime in on that.
It was the perfect evil KNC plan imho.

So anyway their greed NOW allows us to take a clone titan bridge and use it on a Neptune board plug and play with the proper titan SD knc 2.00 software. A few folk had more then one fried Titan board and managed to switch a bridge or use a 4/6 port other controller and get one or two working cards or some such...so some options ..thus we can 'sorta'
 'create' a Titan board.

Just wish we could take that last step and get the BBB project to do Titan cubes and/or that spaghetti hack on a pi protoboard with the an equiv larger clock chip directions in some manner for using a chip other then MICROSCOPIC clock chip with this hack, up and working.

We may as well take advantage of the cheap bastards re-using and making all compatible 4/6 port cards ALL OF THEM EVER MADE and find a work around to run Titan cubes.

The idea of a flashed BBB Mercury Board running a Titan Cube with Gen Tarkin's Software has a certain *FU KNC* appeal don't ya know.

Well anyway others can chime in on here with the back and forth (threats to ban) and other stuff that went on with KNC forums on such stuff as above, back in the day.

Just would like to see the last step taken to complete the loop on this. Either a BBB solution (more elegant) or a re-wire of the spaghetti version above (true hardware hack)

later

Maybe this is simply like that: if you see on the HW status page in which slot you connect your cubes and there is Temperature and DC/DC avg temp showing but the CLOCK is OFF so go to Advanced page and turn them ON by simply from dropping menu on each die from that OFF status set clock which you wish to let them run example 300 MHz and then scroll down to bottom of this page to click on Apply changes.
sometimes if you plug cubes to different ports as they was before, you can get this situation.
I hope this help

Re Neptun controller - I can confirm, its working as normal titan controller with titan bridge and pi with Titans cubes.

Yes.

:-)

The problem with the Pi2 is that the CPU type is not supported in the boot loader/IPL code that was on the last version of the 2.0 Titan firmware. I wonder if you can do an apt-get upgrade/update on a rpi, then boot it on a rpi2.

THat might be the best way to go. Or you can still buy a rpi 1.2 B unit.

C

My understanding is that code for Rpi2 would have to be recompiled in order to run it.  We can't recompile the Titan code because it contains proprietary blobs which are used to run the FPGA on the controller.  Those blobs were not released by KNC because they did not own them, thus did not have the authority to release the source code.  Thus we're screwed.

The fpga code doesn't need to be recompiled, either fpga loader will load the fpga code for titan or neptune as needed.

Try taking a normal pi and running an update on it. If people really want me to do this I'll do it for the hell of it as I have a Rpi2.

Edit: Running now. Will take forever, what the hell.
