I created a bitstream for the ZTEX 1.15y board and want to share it with the decred community.  If you have a ZTEX 1.15y board, you should be able to mine DCR using this modified cgminer and bitstream.

I have put the bitstream at the following link.  It gets about 800Mh/s.

The cgminer is located at the following link:

    https://github.com/sprocket-fpga/cgminer_3.7.2_ztex

Below are the steps I used to modify Decred cgminer 0.0.5 to run on my Raspberry Pi.

    1) sudo apt-get update
    2) sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev screen libtool automake pkg-config libjansson-dev
    3) git clone https://github.com/decred/cgminer
    4) cd cgminer
    5) sudo ./autogen.sh
    6) sudo ./configure --disable-adl --enable-icarus
    7) copy .c and .h files to cgminer directory
    8 ) copy .bit to cgminer\bitstreams
    9) sudo make
    10) Command Line: cgminer --disable-gpu --blake256 -o < url:port > -u < username > -p < password > --ztex-clock 100:100

Note: This miner only works on Getwork pools. It does not have the Stratum logic incorporated yet.

Open Issue: This miner seems to work fine for up to 4 ztex boards. More than 4 boards is causing the cgminer to crash after 10 minutes.  If you have any ideas how to fix this issue, please PM me.
