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

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

Did you used the .hex file from yesterday?

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.

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 ?  

J

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?

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"

try to adjust this value in klondike.h:

#define TICK_TOTAL 20800

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 ?

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.

@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.

 

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

Need help compiling cgminer/bfgminer? shoot me a pm. ive done it many times on linux. Cant help with firmware problems.

Looks like you dont used the patched cgminer version.
You can also use BFGminer, which includes automatic detection of this boards.

Btw (not the problem here): Did you changed the chipcount to 16 in the code? The precompiled one is for the 10 chips board.

I have try both ~

Loading  " Klondike.X.production.hex "

          under ->  by Formtapez_ avalon-master\firmware\Klondike.X\dist\K16\production


Also, try open the project there named "Klondike" in MPLAB X IDE,  and load from there

It almost looks like a firmware problem.
What firmware did you load into the PIC chip?

I have make 2 ~   round about $250/board,  if anyone interested ~

All hardware have been assembled, including a Big Heatsink ~

~~~

I can't really test it , Need to be setup properly for testing ...

Compiling a proper Cgminer  ~ seem real difficult ~ !!

  ~~~ as currently its stuck @ -->


result from CGMiner :

--- ~ >>>    KLN0:0 unknown work (a0:51be99bff) - ignored
--- ~ >>>    KLN0:0 unknown work (a1:92cv34ofe) - ignored
--- ~ >>>    KLN0:0 unknown work (a1:xxxxxxxxx) - ignored
--- ~ >>>    KLN0:0 unknown work (a2:xxxxxxxxx) - ignored


Anyone know the reason ??  Problem solve would means cheaper on Hardware ~ Labour cost free ! For 1st 50G

Yes I have 150 of them. So price will change a bit on numbers you would like to get but generally it will cost less then I pay for them. I made a mistake of buying too many... I'm in EU...

source chips aswell .

Factory is missing one component they had to order it from digikey cause its not avaible here in Shenzhen , so there is another week of waiting again.
