Hopefully, there will be a working klondike cgminer soon. I think somebody is working on it.
Yes, I am.
Not sure why bogart's didn't work, but the team I'm helping a bit with, they are all getting at least some results with the klondike branch in my git.
It still needs some work, but the current code does work with the test boards in the team and gives back '=' results.

Hi, Kano, your codes work but perform with lower hashing rate and give a lot for errors like this

---------------------------------------------------------------------
 [2013-09-26 09:52:54] KLN0: GetResults (amt=0 err=-7 ern=11)
 [2013-09-26 09:52:54] KLN1: GetResults (amt=0 err=-7 ern=11)
 [2013-09-26 09:52:54] KLN0: GetResults (amt=0 err=-7 ern=11)
---------------------------------------------------------------------

I guess it's because of the modified version of libusb in the new cgminer

That is wonderful news. I'm sure that if anybody can get it ironed out, it's those guys.

I'm mining more beer money for you guys with my block erupters as I type this.

Can I just compile it with the --enable-klondike --enable icarus from your git and maybe I won't get stupid usb problems anymore? Do I still need to install libusb?

I don't have a klondike (yet), but I can use the usb block erupters to see if the usb problems that I had before are still there.

Mine have 5 sets of 2x2 pin headers located along the edges of the board.  The boards each came with a little PCB jumper board plugged into one of them.  Any idea what they do?

The boards can connect to each other and send data. The idea is that you can have one board connected is USB to a computer and then connect other boards in a chain. One USB instead of many.

The SW for that is not working yet. I will be looking into this soon.

So right now, assuming we had working K16, you would need one USB port per K16, as the klego connectors and the firmware to drive them properly would not work.

Right?

Are there any updated github forks I can follow? I am also looking for PCBs, but I'd like to have some made accounting for the size difference with the replacement for the 38L361C, MLC1260-401MLP (Part # L1-2), and possibly add backplane power and/or USB, maybe stackable klego connectors?

So after 157 pages is there a working Klondike available? It's a bit sad to see this Open Source Board fail.

Is there any firmware that lives in the device in NVRAM of some sort, or is everything loaded at runtime?

It's all precompiled and sits in the flash memory on the pic.

Are there any known updates for the firmware that might help me?

Mine still won't hash using kano's klondike cgminer branch.  They just produce HW errors.

I believe there is but the boards cannot be chained together yet.

If the price is right on Avalon's firesale gen1 chips, and if there are enough available, this project may get new life.

I think your going to need a hardware change.
Can you find someone near by that can replace a few parts for you?

I can probably change parts if I know which ones.

@bogart, replace C274 with a 220p, or 260p capacitor

Is that the proper mod?  I downloaded "K16+Assembly+Drawing.pdf" from the bkkcoins github and found C274's location on the board.

Buying anything from avalon after all that has happened is sheer foolishness.

There are still a bunch of bag-holders that need Avalon asics to power their miners (if the K16 is ever going to mine). Starting anything after with Avalon, that is foolishness. But, also, business is business. If they turn things around, money will be talking.

C274 is the correct part to replace.
I would also recommend that you replace R45 and R46 with something lower that the 1K resistor that is already install.
Change them to some thing between say 350 to 500 ohms.

I've been thinking about putting together K16 part kits but there's probably not many people building them at the moment. It would include everything on the K16 parts list except the pcb board, Avalon ASIC chip and the PIC controller.
