Topic: FGPA Mining with DE1 and Spartan3E (Read 1343 times)

Sorry, what do you mean by that?

She asked me the same because of her FGPA Bitcoin Mine

Up for awareness! 

 

Hi minernb,

Do you mind shed some light how you change the de2 github code to be compatible for de1? Thanks! 

Slightly off topic but can I ask how you modified the DE2 code to get the DE1 to run?

I've got an Altera DE1 with a CycloneII from a VHDL/FPGA class I took a few years ago but can't figure out how I modify the Open-Source-FPGA-Bitcoin-Miner projects so that my DE1 will run. I'm on a linux machine so I rewrote the .bat files for bash and got QuartusII running but that's about as far as I got! Guess it's been too long since I've played with this board...

Any tips?
 

It is what I got...
As I said, one design reports 12MH/s but does not work...

not on a sparten3E its not

3,14MHash is bad

I just put them down to network communication glitches (the getwork times out or fails to connect). It all works much better if you install a Stratum PROXY server as an intermediate https://github.com/slush0/stratum-mining-proxy

As for your query about makomk_mod, I posted a reply at the main fpgaminer thread https://bitcointalksearch.org/topic/m.1901149

Thanks for the guess, but I doubt it since it was a code optimization, not an overclock.
But that is me saying it. I will try to contact the authors when I am allowed by the forum.

you may have over clocked it too far

Hello, anybody there? FPGA Guys,

Maybe makomk can get to know this post, since I am unable to contact him! I am a newbie! 

I have one Altera DE1 board, and have compiled the miner and it runs at 12MH/s.
But all works are rejected at this rate.
Using the non optimized code, I was able to mine some micro coins, at 3.10MH/s.

Want to improve the FPGA miner? I can beta test it if you are willing to take a look at this issue. Any advice on why it is rejecting all works and how to fix it?

Cheers.

Ok, i have my answer...

I left the thing working and went sleep.

Now, just checkit out, and I have some 0.00005292 bitcoins in my wallet.
I am going to by the World!


Cheers.

Hello guys,

I have these boards and just today discovered FPGAs can be used for mining bitcoins... So I am testing how it works.
I have build the FGPA Bitcoin Miner for my Altera DE1, and when i run th mine.bat I have the following output, and would like to know what is the meaning of that.

What those errors means? Is the boarding receiving any data? Is it trying to process?
How can I know?

I appreciate any help.

Cheers.
