Re: Klondike - 16 chip ASIC Open Source Board - Preliminary

Just an update, still working on it. I've removed all the ASICs. The short is no longer present, so now I have to solder the spares back on.
Hopefully, it will be completed tomorrow (I'm leaving to work in about 45 minutes, so can't work on it now).
I also have modified firmware in hand, so I'll be able to test it right away

@zipiju

I have made two PCB(ver. K16s-1.0.1)

I found mismatch Schematic and Partlist.
There are some errors in the Partlist.

 R21        10K          390R
 R45,R46  390R         10K

@HerrHeimlich

You have to use MPLAB IPE.

Gen1 is different pin map from Gen2.
for example,
pin number #20
A3255-Q48(DVDD)
A3256-Q48(DVSS)

I was change the frequency between 500~700MHz.
Increase in performance, but the result is similar to the previous.

Thanks Form,  u're you superb !    After adjustment I'm now getting 11 - 14 G ~  with almost no error , < 1%.. Cheesy
I'm getting alot of " went idle before work was sent"

Yeah, i get these messages here, too - since months Smiley
Actually, changing TICK_TOTAL adjusts the timeout for one job. When the value is too big/small the result is many dupe/idle messages.
I think 20800 is near the "golden mean". It doesnt affect the hashrate as much as one would think.
I have updated the code (and the .hex) in the github-repo now, too.

Can you tell something about your frequency and voltage settings? Are you cooling the chips from topside, too?
I'm from korea. I don't know english.
I have make 3 PCB.
I'm trying the 1 volt,  16chip is very cool.(bottom side heatsink with fan)
writing new hex file.

Result :
using cgminer cgminer-3.9.0-windows
7~16G show like that, but actually the 0G(btcguild).

using bfgminer-3.8.1-win32
I'm getting 4.65GH/s(same btcguild)

Thank for form.
