This removes some of the debug output which has caused such confusion (overflow and checknonce messages) and added a new command line option to set the ZTEX clock speed manually. Its probably best to let it run in automatic (default) mode at first to get a feel for which settings may be required should you decide to use it.
(to upgrade just copy it over the old version in cgminer-3.1.1-blakefpga).
When running on linux you will probably need to run as sudo, and don't forget to update bitstreams/ztex_ufm1_15y1.bit with the blake version from
or you'll only get a bunch of HW errors instead of shares (yep, I made that mistake too
The updated README is as follows ...
Blakeminer patches for
https://github.com/ckolivas/cgminer version 3.1.1
I don't think its appropriate to fork the repository in this case so I will
just supply patches to specific release versions.
Compilation
Open the official repository (link above) in your browser, click the "branches"
dropdown menu in the middle left of the page, select the "tags" tab and scroll down
to the version required (3.1.1) and select it. Download the zip (right side of page)
and unzip the archive.
Copy my patch files (from this github folder) into the official cgminer 3.1.1 folder,
replacing existing files as necessary. Build as normal, see the README or windows-build.txt
Prebuit windows binary at
https://www.dropbox.com/s/6ydm22w7rclzhj2/cgminer.exeDependancies (DLL) at
https://www.dropbox.com/s/xa01f9hhakpsexv/cgminer-3.1.1-blakefpga.zipTo use the windows version, unzip the dependancies then move cgminer.exe into the folder.
Copy the bitstream folder from the official cgminer-3.1.1 distribution.
Replace ztex_ufm1_15y1.bit with the BlakeCoin bitstream.
Edit the RUNBLAKE.BAT script and set the username/password to be the same as the rpcuser
and rpcpassword set in your blakecoin.conf. Change localhost if running blakecoind on a
separate machine. You will need to install the WinUSB driver using zadig which is available
at
http://sourceforge.net/projects/libwdi/files/zadig/For linux users, run as follows (this is the same as RUNBLAKE.BAT)
sudo ./cgminer --disable-gpu --url localhost:8772 --userpass username:password 2>log.txt
You can probably change the UDEV rules to avoid the need for sudo.
Notes:
Should you have problems, redirect the stderr output to log.txt (this is done
automatically in RUNBLAKE.BAT) and examine this for messages.
Do not use this for GPU mining as it will not work.
Do not enable the --debug switch as it crashes, --verbose works OK though.
Cainsmore CM1 will be detected as icarus, you may need the -T switch if it crashes.
Use the -S option eg. -S \\.\COM20 -S \\.\COM21 -S \\.\COM22 -S \\.\COM23
It will not work for my current lancelot bitstream, use the python miner instead.
Only the ztex 1.15y board is supported. Frequency management is automatic using the
same algorithm as bitcoin. It can be overriden by the --ztex-clock option as follows
--ztex-clock 180:200 sets initial clock of 180MHz, max of 200Mhz
--ztex-clock 204:204 fixed clock speed of 204MHz
--ztex-clock 180:192,184:196,180:204,192:212 set individual fpga device speeds
I don't know if this will work for multiple boards, but its done the same way as
the icarus options so with luck it will be OK.
The clock resolution is 4MHz (rounds down) and the valid range is 100MHz to 250MHz.
If --ztex-clock is not used the default range is 172MHz to 220MHz.
