Klondike - 16 chip ASIC Open Source Board - Preliminary

[Unacceptable]

Now I need to figure out how to get this firmware onto my Mitten Mining K16s.

The ones I that I have running (replaced C274) are only limping along around 2.5ghps now.

Where you located

East coast US.

I'll check with Steamboat,maybe we can do something to help  

Give me a few days  

Can you get a PICkit 3 & would you know how to use it

They're about $35 or so on Ebay,the red one is the one he uses.

I could probably figure it out.  I do OK with things like this.

I already have a Bus Pirate, though I've never actually used it for anything.  I don't know if it would work for this or not.

I have an AVR Dragon also, and some Pis (thinking of their GPIO interface.)

The pic needs 12v to program it, you need an adaptor for the bus pirate to do this.  You could build the adapter yourself.

The pickit is really easy to use, pretty much plug and play.

Yep and someone could help out over screen sharing if needed.  The problem might be the two weeks it takes to get a chinese pickit delivered, might need to buy a real one.

I went ahead and ordered a PICkit from a US seller.  Hopefully I'll have it in a few days.

Does cgminer work with these in windows or only linux?

Steamboat already pasted Klondike project URL to LSD thread, but in case someone missed it, you can check it out at http://projectklondike.org.
And anyone running Klondikes, you can drop pictures of your miners to drop@projectklondike.org. They will be added to the gallery.

You can download sources here https://github.com/zipiju/k16-firmware. For now just sourcefiles, I'll add compiled hex as soon as git starts cooperating with me .

Thanks for all your hard work.  Can you confirm the hex file at https://github.com/zipiju/k16-firmware/tree/master/Klondike.X/dist/K16/production is current.  I got an abandoned K16 proto in the mail that I'd like to bring up to date.

Thanks,
Tom

Yes it's the latest working for now.

Thanks for putting that info up 

I'll post my pics of my Klondikes after I clean up my setup

Well, that kinda worked.  I successfully programmed my 6 K16s using the PICkit 3.

The 3 that I'd gotten halfway working before now appear to be fully working, though I now need to address cooling.  I keep getting "critical overheat" messages.

The 3 that weren't working are still not working.  One gets 100% hw errors, one has a zero hashrate, and the third isn't even detected (I get "usb 1-4.1.4.4.4: device not accepting address 91, error -32" in dmesg, and the USB hub light turns off.)

I used 100% linux to program them BTW, no Windows, and it worked just fine.

Congrats !!!!!!!!!!!!!    Good luck with those others

Sounds like it's time to break out the oscilloscope.

Bogart, there is a failsafe in CGminer itself. Currently it is set to 53.5 deg C. You can change it to higher value in driver-klondike.c at line 63:

#define KLN_KILLWORK_TEMP        53.5

to for example 63.5 is what I'm using:

#define KLN_KILLWORK_TEMP        63.5

Then recompile.
Anyways, Kano is going to change that soon I think. We discussed it, but we didn't achieved consensus yet on which temperature would be the best there.

I just pushed up updated firmware with 333MHz default clock. It should be more stable at the start, so try that. Then you can use cgm config to clock it higher.

Great, looking forward to it .

Sounds like it's time to break out the oscilloscope.

I actually have a fairly nice Hantek DSO on hand, but I'm not really sure of where I should be attaching the probes to measure something useful.

Thanks, I'll look at that, as well as adding some fans.

I'm useing version 3.5.0 & my Klondikes get up to 58c,guess there's no killwork temp,no issues yet & I do have fans cooling the backside too.I'm getting some coupling nuts so I can afix fans to the rear

55 nm is starting auction tomorrow.  I wonder if they're pin compatible and if anyone will trust Avalon again or if we'll just let greed take over.
