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.

Nice job; I've been debating on whether or not to get my hands on some FPGA boards rather than GPUs but I'm not sure what some of the best choices are nowadays (considering Spartan-6 chips are a bit dated). Any suggestions like maybe the artix-7s?
