Do you think Tarkin can modify his code to boot with a later pi version? I would gladly pay to see this done, as I was the first to pay for custom work from him for the Titan miner project.

Problem is, I dont have physical interaction w/ my Titan and henceforth its RPI...so, I cant really chance updating anything that would cause it to not easily be recoverable =(
That's a problem. I put the BB port on the side for a bit, if someone really wants me to blow a weekend hacking a version of Debian/Pi that will boot let me know.

Damn..it would help us greatly if you could become WEALTHY as well as eccentric...to keep the BBB project and others going on here..don't ya know Smiley Work on that will ya?

By the By I assume the Qberty 2nd batch PI fix attempts are also 'dead' at this time? (going for 100% in the wrong direction..its a theme I tell ya.. ..ho ya ..) Sad

I'll put some time on it this weekend, been testing your cube (the cap is back on, the solder was bad, 64mh as seen below) and on a separate controller Johnny's (fun little project, was totally dead, now running fine but occasionally resets the power supply. Run it on its' own supply and it is happy). His other cube is a mystery: Supplies now come up (two shorted), communications restored, but the chip doesn't hash.

As for the BB's I was waiting for a need for more fpga's so I don't do a 5 buck order. Sure enough got another one in for fixing, so order going out for higher pf crystals.

My rb pi is a rb pi 3 model B V1.2. Will this work with the Qberty board? Maybe this is why my board does not function? I did not think of this.
The qberty board has a short on its' 3.3 volt line where it runs through the crystal. That keeps the Pi from even powering up (and might blow up the Pi if your PSU was big enough). I've cleared the short on a test board, but am also fiddling with the crystals.

And in the ter-fucking-ific category, it looks like the Rpi model B 1.2 models currently on Amazon.com have a slightly different CPU and will not boot the stock KNC firmware. So we're dead in the water there.

Stupid micro-code. This could be a problem.


You could be correct  Element 14 has them on eBay and they look like this with heatsinks built in



vs the old without heatsinks included version of Raspberry Pi B+ 512mb v1.2




Anyway ...the pic with the heatsinks may come with the CPU mod you specify. The dates on the board are the same. So maybe there is a way to tell the difference just by the
heatsinks?

Anyway, all I got. Others can chime in if they are getting Pi's w/o this heatsink mod which will make my above point moot. But what I saw on eBay at a quick glance.

So if correct we will have to avoid the NEW versions with the heatsink. (no way to tell used ones if someone added a heatsink thou).

Hopefully at least a guy will have that much as a hint?





How much can that chip mine?

I need crypto in my life and garbage out of it.

I have a titan cube that melted where psu connects...I had it replaced and after that the cube was running fine for about a month( I have two others where I replaced connection and those have been running for 3- 6 months)
at some point system stopped hashing, so I shut down and restarted. now system does not boot up when this one cube is connected.
cube seems to be getting power as fan comes on
I have tried a number of combinations but routine always seems to get hung up at point in boot when really bright led lights up and IP info start flashing on screen....in current scenario screen lights but no text is being output as to status.
when I remove the one cube and boot with the three other cubes everything boots up normal.
any suggestions.?

Cube either has shorted CPU lines or blown buffers. Can you check resistance with a meter between each of the pins on the 10 pin connector and ground?

I have digital multi meter I picked up years ago...not really sure how to use it.  Embarrassed

other wise I could always bring to guy who replaced molex pin connector and ask him follow your instruction.

are either of those two problems fixable ? and do you think they be costly?

thanks appreciate help

How did he replace the molex pins? Can you shoot a pic of the front and back?

Pins 1,3,5,7,9 should not have low resistance. If you see low there then the buffers are damaged.
Pins 4 and 6 are the power supply pins for the main chip logic. If either is shorted you're sunk.
Test relative to ground (the top pins on the Molex).

While I know approximately zero about the KNC hardware, the very Original Raspberry Pi Model B (512 MB), had a 26 pin GPIO header. The subsequent Model B+ that are shown above has a 40-pin GPIO header. My recollection is that the Pi microcode, NOT the stuff supplied by KNC, had to be changed to support the Model B+ and it's expanded GPIO [pins.

So what king of connector is on the KNC hardware? If it's a 26-pin variety, in which case the microcode that's included within their flash image is likely meant for just the original Model B, and may not support the Model B+ (nor the Pi 2 or Pi3).

My apologies if this obvious to everyone else.

It's a B+, but I think their code was developed on a B unit. The earlier B+ units could support the code releases from KNC, but those boot images will not work with RPI3 or (this is what I seem to be running into here) later model B+ because the video chip (which does the IPL loading) is different.

Add that to Rpi changing how SPI devices are enumerated and zero development on the KNC code and you have a bit of a problem.

molex pins I mean the where the power comes...did I use wrong term.
I bought some replacements on mouser, had a guy at real old time electronics shop take off burnt one and solder in new one.
he was intrigued as to a machine that would generate such heat.... so I gave him a brief primer on blockchain technology and distributed ledgers.

So the connector that plugs into the Raspberry Pi is actually 40-pins?

If so, then they must have developed their flash image on a Model B+. As I recall, MOST of the first 26-pins of the GPIO map directly onto the 40-pin GPIO, but there a couple of small differences that don't matter to many applications.

Yes. I think the problem is the later model B+ chips use a new GPU/IPL loader that does not support Wheezy. This is a real bitch.

Question: Does anyone have a blown out bridgeboard that I can buy? I have just about everything working on the qberty boards but I need to move a component on an original BB to check a trace and I don't want to wreck my reference bridgeboard to do it. Will pay .1btc plus shipping.

Meantime more boards repaired, few more brought back to life. Don't run them too hot; don't burn out the plugs.

I was paid .5 btc so likely that is not enough. Perhaps if those interested tossed in 20 bucks each
just to know a real clone bridge work around is out there might get you where you need to be

If enough want such or just assurances on future what they have bridge board fixes. ie you get
proper info from such a fund by getting a BB the 20 bucks is kinda an insurance to get you over such a
hump

Happy new year everyone despite our titan failures

I have a new issue where i've taken off the bridge board from the controller board and the connector has come off and loosened others so now the like 5 of the 10 or so pads have detached.

As you know its almost impossible to repair on these bridge boards so i don't mind shooting that to you but i have a beagle bone from a neptune and would love if everyone could focus on actually getting firmware to control the titan to work on a beagle. Because we don't then need a damn bridge board.

Is that possible mate? Seems like it would cut out all of this bridge board mess we all seem to be in.


any custom firmware for titans???

I added support for custom overclocks if a Titan is plugged in, Neptune and Jupiter pickup the padrino firmware overclocks as well.. The big win here is support for running the Titans with a Beaglebone, no RPi and no bridge board required.

You could contact gen tarkin and ask how he licenses his stuff for sale with a code etc locked into the Titan's say BBB etc

then just sell them to folk who get their own BBB imho ..you probably would make enough at the front end ..then chasing the price down on what you need in BTC

on this...as the A4's come out and swamp the scrypt world....ie what I mean is....dropping your price chasing this may not work as well for BTC up front as

just selling the stuff in some manner above NOW for a price you can get for those interested...

quite frankly at the LTC increase in difficulty and the slow slide of all scrypt coins..this could all be kinda  moot by Feb 2017 or March 2017 at this rate of FUD and price.

Anyway ...folk would buy such now and worry about their own BBB to install it on...I'm not sure what kinda interest you will get on this IF complete Titan units

start dumping on the market again at greatly reduced prices due to the above

anyway my view for what it is worth..you SHOULD have tried to get that BBB price last summer you could have got your 10 BTC at that point..now er ..not so much imho Sad



All good points, I ignored it for a long time when it was sitting here working.. Its a long shot but figured I would dump all of those controllers I have left, Titan cube, etc. alongside the package itself and see if anyone, or a small group end up grabbing it.

I'm doing it since I am focused on my GPU miners right now and don'5 want to somed time working with Tarkin on pulling things together, but maybe it will backfire and I just shelve it all for good.. It took maybe 120 hours to get it all sorted out, but it was a good project..


Dammit! Gentarkin have you thought to reach out to this guy/girl? If not and you do think to then keep in mind they want it to be a easy transition.

Yeah I can fix that, it requires patience, epoxy glue, 24 gauge wire wrap wire, and .10tc to fix :-)

But I will say if someone can figure out the beaglebone thing that is the right way. I spent a weekend whacking away on it, and got 99% of the way there. Just seems to be a problem in how fucking bfgminer is built because there is knc code, knc-auto code, and knc-titan code and the options just don't seem to work right. I have gotten it to at least see the titan dies, but it flunks loading them which drove me up a c wall.

I know the spi lines and everything else is good (and the new spimux on titans can run neptunes) because I have bfgminer running compiled with neptunes. Something's fucked in the titan code though or one library is stepping on another..

The rest of it is mostly some symbolic links to get waas and the web site to work, but that's not a big deal and I can post my raw notes.

The bridgeboard is also nuts, there are three components on the damn thing and the issue is the crystals I can get just. don't. work. I have no idea in my head why, but I am going to take apart one guy's board to find out. Because another guy managed to kill his bb somehow and we need to fix this.

Want to take a crack at it?

Actually 10btc sounds like about what it would cost me in time to hack together the code load on a BBB to a point where anyone could use it. Fair deal.


Probably too late in the game for that price now imho with Zcash mining taking LTC thunder and the A4's coming out 2nd batch Dec 15th

but hey I'd get what the hell I could for it soonest...maybe 10 BTC is fair...no clue..I don't code.

Most Titans are getting buy 6 to a controller if they need to...but they seem to run better 3 or 4 to a controller


Good points all around, will see what happens..

The biggest value is the lack of a bridge board, just take a controller and Beaglebone and you are good to go, I am tossing in all of the controllers I have (I think 8 but need to run another count) plus a Titan cube I held onto so whoever picks it up has a stack to move out with.. I did enough looking at GenTarkin's code to know they can be integrated fairly easily, I missed my window between projects to get it all done so it's here for someone else that may want to press independently, or tag back up with GenTarkin to put them together.

I'm considering your offer, though 10 BTC is a little high (after conversion rates in my shizzy country). When I can afford it, i'd totally take you up on that if you don't have a buyer yet. I think there's only a small handful of Titan owners that can even make use of it. Maybe an auction would be more relevant?

There is a market for this to be developed right? So lets source the 6btc and get it done?

Yeah i mean if you want the board you can have it, so you can research it. If i ever get my hands on another i will definitely be using epoxy to hold them on better. Such a stupid design.

A mate of mine is jaded i think, he fixes taxi hardware and comes across this type of thing a lot and throws it all out. He cant seem to be able to tell what else is on the bb without pulling it apart of course and says he cbf playing with it.

I would like it fixed but i really think its a better solution to focus on the bbb as you know it can just go right onto the controller board which is a better solution.

In short, i don't mind sending the bb if you really want to explore it more. Personally i don't think its where we should be heading.

What would be even better is a adapter to run this off a pc. In some circumstances of course.

Here is a picture of my bb for reference to my...current issue.
