Open Source Avalon Gen2 55nm Board

[form]

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).

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 ?

try to adjust this value in klondike.h:

#define TICK_TOTAL 20800

[hongkongapple1]

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

Thanks Form,  u're you superb !    After adjustment I'm now getting 11 - 14 G ~  with almost no error , < 1%..

I'm getting alot of " went idle before work was sent"

Yeah, i get these messages here, too - since months
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?

[hongkongapple1]

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 ?

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.

Did you used the .hex file from yesterday?

[cdragon]

Did you used the .hex file from yesterday?

yes!
I apply yesterday hex file.
old hex file is display ignore.

[hongkongapple1]

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

[cdragon]

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.

[form]

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.

[cdragon]

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

[hongkongapple1]

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 ? 


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

[hongkongapple1]

if that is still true on 16 chips board ?

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

[cdragon]

if that is still true on 16 chips board ?

I'm writing a blog every day about making the this board.
My blog name is say "indu dot com"

[form]

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?

[hongkongapple1]

if that is still true on 16 chips board ?

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

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
