    Marecel1973, if you decide to try again, PM me and I will walk you through the steps on the ztex web site that show you how to configure and use your board. As I said, fpga's can be hard to learn...

    Hey Sprocket, thanks for making your bitstream available. The dropbox link was taken down, would you mind uploading it somewhere else. Thank you.

    It looks like dropbox has blocked my account from sharing due to high traffic.

    That sucks.

    Do you think you could upload it somewhere else? I use https://dropfile.to/ for work sometimes but the files only last 24 hours. I've seen some use media fire though I've never used it.

    I'm not sure why dropbox flagged it. I'll go ahead and remove the file from dropbox. Regardless, I only posted it to help a guy out, you really should be compiling your own code.

    compiled cgminer for RPi
    uploaded bit file in the board
    but I see a lot of HW errors, even at the minimum frequencies
    this is normal?
    sprocket, can you also upload ihx file to github?

    Hi Chugumoto. I think that version gave a lot of HW errors for certain chips (as you can see, your #1 chip is just fine with it). I use a completely different design now that gets far fewer HW errors and when I get some free time, I'll try to build and post an updated bitstream. It's your call if you want to continue running with the version you have. But if your chips are not overheating, I don't see any issue with it.

    I'm working on a different board right now, so it may be a couple weeks until I can post the updated bitstream.

    according to the heating of heat sinks there is not overheating
    on mining vcash it works stable

    You realize vnl uses a different algo, right? It has half the rounds of dcr and a different block header.

    Also, I already posted the code for xilinx chips on my github...it's up to you to customize it to the specific board you are using if that is what you are interested in doing. I will not be posting the code that I run on my personal fpgas.

    I have posted an updated bitstream on my github. It should run a bit faster and get fewer hardware errors now.

    I have also updated the cgminer code to integrate simple serial fpgas like the BeMicoCVA9 or any serial board with a single chip using serial comms.

    cgminer see only errors now after decred coinb2 field update. As far I know it uses GetWork with long polling only.
    Any thougths what shoud be updated ? Is it possible the issue is related only to pools software ?

    I think this has to be updated https://github.com/decred/cgminer

    Then we can recompile with Sprocket's instructions on his github.

    If anyone has the code stored from https://github.com/decred/cgminer/ (now removed) -- Please send me a PM. I should be able to patch the code to get it going after the recent changes.

    I don't think that the kR105-zz branch has ztex 1.15y support

    Edit: OP's code doesn't work with the kR105-zz branch. Lots of compile time errors.

    The code is still in the repository. Just check out the commit before everything was removed.
