I know that the driver for gen2 Avalon needs to subtract 0x180 from the returned nonce but are there any other changes?

There was a limitation (999 MHz) for the command-line parameter for the desired chip-frequency in some versions of cgminer - That has to be removed or changed to 5000 or so.
Thats the only thing that has to be changed, additionaly to the 0x180 substraction (which BFGminer detects automatically).

@form
After looking at the Avalon data sheet I don't see how to get the clock frequency above 999mhz and satisfy all 3 equations.
Were you able to decipher the data sheet and set the core clock frequency at 1000mhz or above.
If so what values did you use for F,R & OD.
Thanks for any help you can provide to understand this.

You can see what values are used, when you look at this function in the firmware:
https://github.com/formtapez/avalon/blob/master/firmware/Klondike.X/klondike.c#L307

The newest datasheet shows slightly other formulas, i didnt got it to work that way, still using the formulas from the older datasheet, works fine.

Will going to try the one compiled by T later on, 
mean while this is the output I'm getting ( with only chips no. Have been adjusted )

And also possible to pop the soft in openWRT ?

for all of us here  ~~  Merry Christmas  ~  Best wishes  Kiss

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 trying the 1v ,  bottom with ( Heat Sink +  Fan ) ~  For The Front Fan Only~   I was thinking of putting Heatsink at front..  since the Chip rise its temp. so rapidly ~  I try around 3200 - 3600 !    

Do u think I should also try +/- Tick_Total too ?  Wink

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.

Cdragon,

You use bfgminer-3.8.1-win32, with which driver on windows?

The standard Avalon 2 Prototype is clock bewteen ( 1 - 2 K MHz ), i try keep trying the figure

I used zadig(v2.0.1.162)driver with windows7.
This driver is mount Univeral Serail Bus devices(K16).
I don't know how to adjust clock.

I don't know how to adjust clock.

You should add this to the parameters of cg/bfgminer:
--klondike-options 1300:70

First number is frequency in MHz, second is desired temperature in °C.

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

Still Trying to Optimum the speed ~ usually over 3000 will have 100% no Rejected ~ 

Now I got top side with HeatSink too..  Result is very different performace, much better !

but still the arange is around 13-4 G

Is there a way we would know if all single chips is working ?  Roll Eyes


~~  Mine only works in CGminer,  I have the driver installed before, but still don't see it in BFGminer ~

if that is still true on 16 chips board ?

hash unit working clock frequency = XCLKIN frequency * F/(R*(2^OD)).

One important thing i forgot:
The value of MAX_WORK_COUNT in klondike.h has to match the value in the driver of cg/bfgminer.

In the github-repository i set it to "8" everywhere.
So when you are using other non-patched mining software (bfgminer for example), be sure to change it to "8", too.

@cdragon: Why are you hashing at 500 MHz?

Form :  We need oscilloscope for the ~ TMR0 Time period (uS) ?

            also if ~  2^18 hashes per tick ,  still valid ?


Cdragon:  Nice Soldering ~ the board looks great ~ Nice slot
