Indeed. I have seen a few Rpis that basically short their +5 charge pump circuit. Since this is powered directly off the main power supply unit through the controller board without a fuse you wind up with a big solid dead short. The weak trace is under the bridgeboard, that's why it blows up in the first place. Fixing the trace isn't difficult but you need to replace the Rpi at the same time otherwise the new BB will blow open too.

I have a rev2 BB and some other things here for this weekend, going to be a lot of work tomorrow looking at some of this stuff. But if someone on the planet can tell me the BOM for this board or the Titan/Neptune I would appreciate it.

For the rest of the group, I have a Rev 2 bridgeboard that just came in. If you have an original bb that's blown I can probably fix that but you also need a new Rpi (Amazon has em) (send it and the old Rpi over), let me know.

I was thinking of a way to short the controller board to prevent it from providing power to the Pi, and just supplying external power to the Pi. This would require two power sources but would be way safer on the bridge. Waiting on a new shipment of Pi's to see if I can test out those issues and come up with a surefire way of fixing this without having to add anything to any of the boards.

Never mind, I see what it is. It's a 24.576mhz crystal, reason being the BBB will output that signal out from the board itself, while the Pi can't do that. So KNC had to create an external frequency base off that crystal.

Interesting. Did you put the crystal in upside-down qberty?

C

Edit: Weirder. Something weird is going on the first couple of pins. Not sure why, but different from the other boards. Odd.

They aren't upside down funny enough. They are identical to my batch 1. My batch ones worked even on faulty Pi's. The batch 2's are the exact same designs with no change except textual (which is far away from any danger).

Well still if you had a NDA i assume the China fab folk you had to sign one. Because they MADE
YOUR bridge. So just have lightfoot sign a NDA as a Tech you have to FIX your bridge boards

If the China fab folk did not sign a  NDA then a contracted repair tech would not have to either

To be safe call the KNC bankrupt law firm but if no  NDA China fab folk none sure is not
Needed for lightfoot to fix unless you need one yourself not to copy your work

Again the only questions can be resolved with an email to the previous posted KNC bankruptcy firm

In my previous posts.

Not super comfortable with NDA's. I've been sharing my knowledge here as a matter of course, and I'd hate to not do that. Service to the community. However if people consider the name of a chip used on a board to be restricted information then so be it; I'll continue to go it alone.

Moving on, with the Qberty design the Pi power goes out when I plug the Pi into the Qberty board. That's odd. However if I lay the board down at an angle to the connector so just the first two pins connect it comes on. Which means something is odd in the first 10 pins on the Pi-Qberty board.

More working today. I fixed the bottom pins on that sacrificial board Searing, now I'm going to pull the top pins to see what's up if I can't rig up a quick header.

As to the KNC NDA stuff Qberty should just imho  email the lawyer in previous posts the guy  always replied promptly to our liquidation purchase emails which mainly went along the theme...".er huh are you really really legit and representing KNC or are we gonna get screwed on this wire transfer"....in veiled terms we.....were...MUCH MORE then  a bit paranoid it being KNC and all ..he held our hand nicely) Smiley


thanks for the update ..I did not want to ask ....the KNC stuff is so flakey it could have sent you off into a legitimate rage as a result and you'd have looked for a hammer Smiley

by the by any hope of the full cube that went away just blinking a white light in memorial to its past up to that point full cube hashing?...

the other 2 1 die only boards as well I guess anything up with them?

(now I went and done it ....showed him all the crap he has to work to REVIVE AND LIVE AGAIN...so he is off ranting "I'm an engineer ....not  Jesus damn it!
...jeez..hope he can't find the hammer) Smiley

Yeah the batch 2's are the ones with issues that I just had issues. I think the issue you're experience might be an isolated situation. But you're welcome to try on some more (as I have a couple more laying around).

In my opinion, I think all of KnC's specs should be public after all this, and i'm trying my best here. I'm not a part of KnC and can't even grant NDA's like that. So lightfoot would be out of luck if he were even into getting it. but that's more hoops to jump through than it's worth. I'm working on some things to make it easier for everyone on the software side of Titan customers. I wish I could do something about the neptune customers, they are in the worst position of all.

Oh I'm hardly out of luck; I'm just stuck using my brain.

So far two of the Qberty boards shut down the Pi on powerup with nothing else, I'm going to try #3. And I got another mumbler working, and I have isolated the short off pin 4 to 6 only. Still not there, but that does narrow things down somewhat.

Back to work.

Oh I see what happened. He didn't short the +5 volts to ground. He shorted the +3.3 volts to ground. Which is produced by the Pi on pins 1 and 17. I can tell because the line from 1-17 that goes to two vias is shorted to ground before the first via. It then is supposed to attach up through the second via to the cap for the crystal, then go down to the main controller board (not sure if the main board uses 3.3 sourced by the Pi/BB. That would be odd since they have a perfectly good TMS chip there on the left....) I can see it's still grounded at the bottom of the board, will try seeing if I can figure out which via (or both) is shorted next.

Cutting that trace gives me a pi that will come up on the qberty board. Not going to try to hash with it (the crystal is powered by that 3.3 line, so it needs to be intact somehow) will see if the mainboard provides 3.3 as well. Maybe I can hot wire it.

Oi.

Edit: Found it. 3.3 is needed on main board. Working to re-mediate the error.

ouu that sounds nice. Let us know. Though keep in mind, the main board does not source up the chain unfortunately.

No I meant the reference to getting them working without modification. I think if the current design is dealt with, I can move on to getting rid of the need for it in a controller altogether. Can't even modify the size of the PCB without the main board getting in the damn way.

**I'll post some high quality images of my working batch 1's and batch 2's for comparison.

Kicking out a link to my post in the goods forum, I sat on the firmware for a few months now thinking I would bundle it and sell it in partnership with GenTarkin, just don't have the time so I put it up for sale since it hasn't been distributed anywhere yet..

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

Main reason folk want the titan bridge is to put their problem cubes on a separate controller..for example I sent 1/2 cube worth of hash to lightfoot to try and fix
and my has rate went down less then 10 ...so I figure if gen tarkin is bringing your 5 and 6 cube controllers up and down to tweak

If there were titan boards enough to put your 2 or 3 cubes on their own controller you'd make up the hash

in my case from past up/down with problem cubes between controllers on 4 rigs in my basement 1 6 cube 3 5 cube.....If these 2 problem ones come back and
another one to make 3 was put on there own little controller I'd gain 1 cube back in hash

i have a controller bridge KNC I got used worked so will do that ..but would be nice to have yet another as a spare and to use as a 1 cube test rig

that also is the draw on these 3rd party solutions to the controllers

but again.....if you have a Titan up  you are probably getting by....so not sure of the market anymore for such solutions....just what I've seen on my 'evil' knc 'we want to
brick ourselves if possible" cubes

the Gen Tarkin software keeps them in line..but lots of up/down/running around by the stuff to do so Smiley
 as
anyway I know zip just my 2c of what I've seen on my 90 day wonders that still run as of this month 2 years and 1 week

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.
