It is recommended not to leave floating inputs, so you should add a resistor on MISO, but this is not your (only) problem.

For chainmainer there are some definitions in miner.h which you should set according to your board or it will cycle for MAXCHIPS which is 256 by default

You may also try Legkodymov's cgminer fork, but there are also some settings to configure (in butfury-config.h) before compiling

Hey,

Can someone explain this:

It's one chip mounted on board ... i don't get any hashes etc ...

There is no resistor on miso to gnd atm

core voltage 0.79v

iovdd 1.82v

...

Very nice chips indeed! And incredibly hard to kill too! Truly awesome design!

And you could only imagine how many months of hard work we could've saved if there was also just any kind of documentation ... Oh well, I guess we can't have everything

Very nice and clean - these really are simple chips to work with - thanks Bitfury! 

Hmm, so you're going for 4-layers with blind vias? Who's fabbing your boards, and what's the cost premium on that? Wouldn't it be simpler/cheaper to just do all over backside solder mask, including the vias? 

Good luck with debugging your prototype - have you got the rest of the chain where your other chips would usually be tied off properly - I think you probably need to tie off OUTMOSI (or OUTMISO - whichever is the INPUT) so that you don't get crap injected into your SPI chain.

Here is how my board looks like:

(ignore the 4 pins that appear to stick out - they're not there.  I couldn't find a proper 3D model for a surface-mount connector and used the through-hole one)

I am building custom heatsink too, so i want to avoid any traces on bottom layer, even vias will end at mid layer 2. that is the only reason i will jump to 4 layer board. and my prototype not working yet, i am not sure why, chainminer detect chip (i think)  , when i start chainminer with 1 chip on module i get message 256 chips detected but not hashing or anything, when i start it without module i get 0 chips detected  ...

And at the moment having troubles with legkodymov cgminer. i just cant compile it. i am using same method as for ckolivas cgminer but with no success 

Ckolivas cgminer is working with just:

clone git

go to cgminer folder

./autogen.sh --enable-bitfury

make

 

Any reason you're going to swap to 4-layers once you've proved that your 2-layer prototypes work? I'm looking at about a 70% price hike to go to 4-layer rather than 2 for my boards...

Thanks - well, that's one vote for 2-layer

Yes, i am using txb0104 on spi bus, and i have only one chip mounted on board at the moment ...

So the chainminer should work with one chip too ? and up to 256 in chain ?

Does anybody have rpi connector diagram for V2 M boards ?

You use lvl shifter from 3V3 on raspi to 1V8 for BF chip on SPI bus ?
If you have chip connected in chain, make sure the last chip have  MISO signal tied 1k ohm to GND.
No matter how many chip you have in chain for miner software. You can work with 1 up to xx chip in chain.

Thanks,

i will try it now, does it need to be compiled or just cloned ?

Use cgminer from here: https://github.com/legkodymov/cgminer

Hi,

yes i used V1 image from dave's thread, and then i compiled cgminer with --enable-bitfury on arch linux.

i didn't try anything else yet but i recheck all connection 5x and everything is ok, i change the chip and still the same ...

Does chainminer can work with 1 chip

Cheers,

Did you start raspi with image from Dave or Punin thread  ?
Cgminer required compilation with parameters --enable-bitfury

Hi Guys,

Nice to be here again,

Can anybody tell me which cgminer to use with single and/or chained bitfury chips on raspberrypi gpio ports ?

My boards are finished everything works fine but when i solder one chip on board and start chainminer it detects 256 chips and nothing happens. cgminer 3.5.0 dont detect chip at all ...

Here are some pics of finished 2 layer boards ( for testing only ) final will be 4 layer ...



Cheers,

Ginger - I got the NanoFury on a single layer
The entire back side is just GND. I am dealing with one chip though. 

With some manual routing I think I could fit a bunch of chips the same way and keep the back clean from any tracks. Maybe that will cost a few 0 ohm resistors to do act as a "bridge", but that's very likely going to be cheaper than a 4-layer board.

Does anyone have a multi-chip board working stably on a 2-layer PCB?

I'm just about done on my 8 chip PCB design, but I'm wondering whether I really need to add a couple more layers for VDD & GND. At the moment I have >90% planes on the top and back sides, so I'm tempted to just try 2-layer, but the cost and turn around time of getting it wrong and having to respin are making me tempted to chicken out and go for the more expensive 4-layer option straight away!

It's working! What are your plans for this board? Manufacture it, opensource it, both maybe?
