Ok. Some FPGA's have built in EEPROM that people load the code into. Which pretty much precludes modding it in the field as you need either a Jtag tool like an Atmel Dragon or a Xylink tool to whack at it.

Got the power chips off the board, waiting for cooldown so I can flux and retry. Also checking the caps to see if any shorted.

Yeah, its loaded into the RAM on the controller board and executed. Thats why it has to be loaded up each power up.

Likewise, if someone wants to mail me a neptune set portion PM me as well

The rule of thumb has been so far, that nobody is willing to go out of their way unless it benefits/safeguards them.

The problem is people have to test this stuff. And I doubt anyone with a running Titan is willing to take their system down, buy a working Neptune board, plug it all in, see if it works, then put their old system back together. If someone wants to mail me a Titan cube and a Rpi adapter+board feel free to drop me a line.

Sure, but isn't the FPGA microcode loaded as a part of the boot up process?

Okay then, nevermind. Only way to go back and forth is to flash the nands or freeze dump ://

Yes the FPGA code is different for titans vs the SHA knc products for the controller board.

don't think they are compabible from what is on this thread...what you can do is replace the raspberry pi B+ (512mb is it) in case it is the PI..if not you have a 40 buck PI to play with.....there is a guy selling Titan bridges here...so see if that is burnt out (between pi and main board)

again as far as the 6 port board from what I understand they are the same but the FPGA chip is programmed for scrypt on the Titans not sha-256 on the neptunes/jupiter/saturns/mercurys etc ..thus it won't work *unless knc in the goodness of there ..hell i can't even fininsh that line...knc won't release the code for such..)

So those are your options (could be a ribbon ...try a different PSU and leads.....check the ports (solder points) on the controller board)

others on here will have better info ..all that comes to mind .....I have limited skills...just the above is what I think is correct.





huh....? I thought the FPGA on (software) on the 6 port board was different and knc would not release such? want you to be right thou ...clarity...GLEN we nee CLARITY ON THIS!
(yelling does not help but makes me feel better as I type this and shout at bitcointalk ...man  I need a life)

I did a couple prototypes from a lab near my old school, and just decided to order enough raw materials to make 10 over there by making some kids slave away one by one. It would have been cheaper to just send it to china/us fab lab to mass produce it but I doubt there is enough buyers to warrant that, so I just made a bunch of super high quality ones (Honestly I wanted the PCBs to be white since I like white and it looks a bit classier, but I just settled on cloning them exactly).

Nice job too, where did you get them made? Looks like a pro job, and if they put the parts on then that has really come a ways from the last time I had PCB's done.

Yeah that's basically what I did to make the Bridges. So I guess it's settled then. We can use neptune/jup boards with titans (as long as we get a Pi 512 RAM and a bridge to connect it to the board). Good to know.

Very similar, now who has the balls to pull off the Pi? Oh wait, is the Pi on top of a board by default? Then That is how they did it.

Ok, now I see. What KNC did is this:

It looks like they took the Neptune board:
Added a cross connect board to map the Beaglebone pins to a Rpi. Added lights and a U4 thingie. Maybe a clock crystal or a VRM.
Plugged cross connect board into Neptune board
Plugged Pi into cross connect board
Uploaded code into the SPI ports on the FPGA
Went to town.

You can probably build your own cross connect board by looking at the neptune pins, matching them to the BB Black pins, then cross-mapping those to a Pi. Power, SPI, GPIO ports, done. Or just pay the guy above who did it.

Here it is

Ahh crap thoose guys are not really helping you in your advetnure :/

BTC LOVER

My Titans controller board is not working. Only one led light is green. Display doesn't show anything. I can connect it but it doesn't find any miners. If anyone knows what to do, please tell me. Also, if anyone has spare controller boards to sell (Titan controller card is compatible with both the Jupiter and Saturn controller cards) please pm me.

Just an update on the bridges, i've sold 3, only 4 left to sell.

**EDIT** I'd appreciate it, if everyone would stop PM'ing me about schematics. I'll make them public as soon as i've insured the lifetime of my set of titans first (selfishly I know). Forgive me for being a little butt-hurt about constantly not having my titans fulltime.

hey yall

I have a titan cube with 1 die giving me hassles, was fine when I got the miner not to long ago.
I ran the cube1 through about 4 hours in a hot room at 325mhz (was a hot summer day + the aircon had a fault) and when I got home the die in question was hashing slower more unstable so to speak.
I removed the cube and played with another until a couple of days later plugged cube1 back in and it seemed to hash normally all was fine... strange.

then a few days later it was dropping out and hashing slower, I ran it on 100mhz down from 325mhz and was hashing normally about 7mhs stable.
changed it over the next week or two sometimes would run 300mhz fine for a couple of days then would go back to the start.

I also noticed that the die would always say in putty on bfgminer start up "die 4-0 configuration failed"
but when I could get it to work it would submit shares ok so I didn't really worry about it well not completely lol.

Now the die is not very happy at all, refuses to do 300mhz. last night I got it to hash not for very long at 225mhz but on lower speeds it would hash initially then after about 15 min fail and was sitting at fat 0 speeds.
I did notice that when the die would hash the load on the power module was showing a larger difference than normal.
for example at 225mhz speed on the dcdc was 0- 27A
                                                                    1- 24A

if I selected say 300mhz the die would show it was using full power in the advanced screen on the webgui and would look like
                                                                    0- 38A
                                                                    1- 39A

much closer together an appearing normal but despite using full power the hash would always be 0

anyone had a similar experience ?

I'm wondering what could be the issue, I'm more convinced its hardware, maybe leaning towards faulty power module.

any thoughts?

Alright *UPDATE* on those titan bridges for those that need a brand new one, and those that want a backup.

Here's the image of what i'm going to go pickup from the lab tomorrow.



Again, they are 0.5 BTC each. This is a non-negotiable price, and those who want/need them please e-mail me so I can send them out to you as soon as I get them. These are brand new bridges with copper thickness reinforced to last longer so it won't burn out like my last three did -_-'

I've made 10, but will be using three to replace some sets that burnt out, and will have 7 available to sell. I'm most likely not going to be making any more.

not big on taking board apart did  you look at the swedish guy's videos on youtube...just do a search on youtube on knc titan are the newest ones

the swedish one (1st) has the best video

the 2nd english one not as good but in english

links are on here but a search works on youtube

I had a pic of the whole Titan works at one time ..will look for that pic


https://www.youtube.com/watch?v=O-RBI4am-wY swedish

https://www.youtube.com/watch?v=-G_zcJ0vbOw english

i had a titan pic someplace will keep looking


by the way remember this from 2013 knc MARS prototype....so still want to get pexiglass and set up my 8 titan cubes in this manner lol



back to on topic: SOMEONE ON HERE MUST HAVE A PICTURE OR LINK FOR A TITAN PCB BOARD?

Searing, can you post a picture of your Titan controller with the Rpi on it? I'm bored while waiting for Santa to bring FPGAs and power circuits from Digi-Key.
