Sandor111, can you recompile me a version which allows 838 freq for my blades? Right now it only accepts 825 and 850. I turned off autotune.
That's just a display bug, if you set it to 838, it will show as 825 because it does 838 - 838 % 25 |

Don't forget the "\\.\" --gc3355=\\.\COM11,\\.\COM12 |

i already downloaded the one from crypoblog, then i downloaded sandor111 latest file - which was just the .exe file. the one from cryptoblog had a libcurl_4.dll in it not just a libcurl.dll. i found a libcurl.dll easy enough now its going. pool now shows 720! before the autooverlcok has kicked in. nice! Great work sandor, but i really miss the summary at top of the miner app - like in bfgminer, and cgminer. how easy would it be to add in  ? if it wasnt for the whole complie on windows lack, id knock somehtign up myself. trying to compile it on windows puts me off though. I need to start learning ncurses. |

I tried the "simple" instructions that are listed in just about every readme/build.txt and I also tried these http://pastebin.com/p2cRgHxd ...no luck with either. Compiling this stuff in Windows is a real b*tch. I'm going to attempt it again after work on a clean system, the one I've been using is full of all kinds of crap and really needs to be wiped. I've got it to work, but I can't recall the exact steps I took... all I know is that it was a mess. BTW, and sorry for off-topic, I've just compiled an optimized build for Windows (disable FIFO & flow control) + pool hashrate display. https://www.dropbox.com/s/7z1cj75mhvojjah/minerd-sandor111.exeThis seems to push the pool hashrate beyond of what the chip is hashing at, or maybe it's just variance, but there is definitely some improvement. |

Left part is BFGMiner, right part (after 5PM) is CPUMiner. Notice the difference in rejected shares, nice huh?  Very nice! Going to try getting this working again tonight. Anyone know how to get a list of USB devices on Ubuntu so I can list them on the command line? sudo ./minerd --gc3355=/dev/ttyUSB0,/dev/ttyUSB1 --freq=800 --gc3355-autotune -o stratum+tcp://pool.com -u user -p x ^does not work for me 
Are blades supported on this Firmware?
Not yet, I'm still figuring out the best way to distinguish a Blade from a standard 5-chip. Serial number maybe? That does not help me, it's the serial from the ST32 chip. |

ok heads up : bit off topic BUT can someone either
A) explain clearly
or B) show me where ie a link
on how to complie the source codes in windows - prefererable x64 - for bfgminer/cgminer/cpuminer.
Ive got a few thoughts and ides id like to try with the grids, but itd require moding the source a bit and a recomplie. tried compliing one of the source codes in the past on windows and got completely lost. heck wis´h i had linux system its so much easier. Oh the idea WONT help wiht over clocking the grids before anyone asks. Thanks so much in advance. Feel feel to send me a PM so as we dont stray off topic.
Download link for Windows is here: http://cryptomining-blog.com/2113-new-cpuminer-fork-for-gridseed-asics-with-hashrate-reporting-and-other-useful-features/More info in my signature. On how to compile for Windows, this is really tricky to get working. Basic Windows build instructions, using MinGW: Install MinGW and the MSYS Developer Tool Kit ( http://www.mingw.org/) * Make sure you have mstcpip.h in MinGW\include If using MinGW-w64, install pthreads-w64 Install libcurl devel ( http://curl.haxx.se/download.html) * Make sure you have libcurl.m4 in MinGW\share\aclocal * Make sure you have curl-config in MinGW\bin In the MSYS shell, run: ./autogen.sh # only needed if building from git repo LIBCURL="-lcurldll" ./configure CFLAGS="-O3" make Lots of fiddling with linking libraries properly in MinGW to get it to work. |

Can someone point me in the right direction for getting this to run on a rpi? I'm a complete Linux noob, so any advice is greatly appreciated!
Login as root, or use 'sudo -s' if using another user: apt-get update
apt-get install -y build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake screen
git clone https://github.com/siklon/usb-miner.git
cd usb-miner/software/cpuminer
./autogen.sh
./configure CFLAGS="-O3"
make
I also suggest to run 'rpi-update' and 'apt-get upgrade' to get the latest firmware and updates for your Raspberry Pi. Mr. Jinx, Thank you for putting this together. I ran all the commands and everything went smoothly. However, after rebooting, it still starts up Hashra Controlla (which came preinstalled). Should I start with a fresh Rasbian image or is there a better way to fix this? Sorry for the bump, but being a Linux noob, I'm not sure what to do next. You should try this on a fresh Raspbian image, that would be easier. |

I'm trying Sandor's new build of cpuminer but not sure what to put as the COM address? In device manager my STM32 virtual COM ports don't seem to have COM numbers. Any advice greatly appreciated, thanks!
p.s. I tried --gc3355=STM32 but this didn't seem to work.. still fails with "GetLastError:2".
Make sure to uninstall whatever drivers you have had installed (zadig etc.) for the STM32, then replug the USB and it should show up under COM ports. Zadig doesnt appear to be installed as such, as I understand it, Zadig is a standalone .exe that lets you change drivers? I tried changing the driver to something other than WinUSB (with Zadig), uninstalling from device manager, and uninstalling the STM software. Still the gridseeds get instantly recognised as virtual STM ports with no port number when I plug them back in. Is there something else I need to uninstall? I had read elsewhere that finding the COM port number wasn't necessary if you just set --gc3355=STM32 in the bat file - but this doesn't seem to work, in your build at least. Also I tried setting the COM port from 1 though 15 in the BAT file to try and find the right number through trial and elimination, but no setting worked for me. In the device manager right click the virtual STM32 and uninstall the driver make sure to click delete the driver software. Plug back in the gridseeds and wait for them to be installed and assigned COM ports I did check "delete driver software" when I removed them, but they still seem to get detected the same when I replug the USB, with no port numbers. Yah, personally I don't feel that the latest cpuminer pooler is quite there yet. Nice try though!  I'm sticking with cpuminer oc version as it has been working perfectly for months without any drop outs. Running several screens is of little concern when using scripts to run the whole smash anyway. I'd like to see real time local hash rate in the same type / current screen, not some all together different version that now needs to be debugged by some end users. He is having trouble getting the COM port detected in device manager, AFAIK this has nothing to do with cpuminer. |

I did the 49.9k resistor mod, but I'm having an issue:
For some reason, although the Gridseeds are running at 7.65 Mh/s collectively, I"m only getting around 3.6 Mh/s effective. It's like this no matter what pool I use. Is this normal, and if not, any idea on how I can fix it?
Can yopmeone join in here and tell what the actual problem is ? I have to say that i face the same problem with the bfgminer. On Ubuntu when i use cgminer, i have to restart cgminer very ofter as there plopps an libusb error. On BFGminer verything runs as it should but the effective hashrate is extremely lower... Try the cpuminer in my signature, it should work without issues. |

I have 5 gridseeds running on a raspberry running cpuminer, after about 10-15 min I get an error and it shuts down.
Here is a copy of what the error says:
...
Anyone have a bright ideas to fix this?
This isn't the right place to ask for support for a cpuminer fork, you should PM me directly (include the full log contents). |

ah, thanks. now i can “spoof“ that with a proxy on my laptop What's the log-in info to SSH into a TP-WR703N? Do we just copy over the bin file or how do we update? It's all in Chinese at this point. sandor told me to upload the v1 bin directly to the chinese firmware. - So thats what im goin to do when my new one pops in the mail How? All I see is the usual tp-link software in Chinese? No upload/update option that I can see. There is an upload form somewhere in the Chinese firmware where you can upload the bin, this will help:  |

Is the point I've drawn the arrow to in this photo supposed to be bridged or not from the factory? I'm troubleshooting one of my gridseeds that has a few more errors than the others and I previously poked around that spot by mistake. I just can't see it well enough to tell if it is bridged or not. Any help would be much appreciated.
Measure the resistance between those 2 points, if you're getting hardware errors at 850 MHz, the chance is that it's setting the voltage below the default. |

cpuminer crashes with this .bat file, I click okay on error then it works. Is that because this won't work with betarigs since it doesn't keep checking that pool to use?
:loop
minerd.exe --gc3355=\\.\COM4,\\.\COM5,\\.\COM6,\\.\COM7,\\.\COM8,\\.\COM9,\\.\COM10,\\.\COM11 --gc3355-autotune --gc3355-chips=40 --freq=825 --url=http://eu.betarigs.com:3333 --userpass=rrob-4660:x
minerd.exe --gc3355=\\.\COM4,\\.\COM5,\\.\COM6,\\.\COM7,\\.\COM8,\\.\COM9,\\.\COM10,\\.\COM11 --gc3355-autotune --gc3355-chips=40 --freq=825 --url=stratum+tcp://useast.wafflepool.com:3333 --userpass=BTCADDY:x
goto loop
pause
You forgot to add "--retries=1", and I don't think http protocol is supported, or I might have removed it for no reason. And yes, as maxzilla pointed out, it doesn't go back to check the previous pool if the current pool is working. |

Thanks for sharing it sandor - this looks so great. What a genius idea to autotune per chip. I started at 950Mhz on a Vmod1 Gridseed.  I just checked and all 5 chips have made it to 975Mhz on autotune. Does this: minerd.exe --gc3355=\\.\COMxx,\\.\COMyy,\\.\COMzz mean one instance for multiple 5 chip miners? If so, do you total the chips or does it default to 5 chips per com port? Yes, it's one instance of cpuminer for whatever number of miners you have connected. By default it's set to 5 chips per miner. How can I adjust the freq from 1 chip? From all 5 (On one of my devices) only chip 3 gives HW errors. I want to clock only that one down but keep the rest at 1000Mhz. Thanks! That isn't possible ATM, but I can add support for that. |

Git repo is now @ https://github.com/siklon/cpuminer-gc3355That's great, now people can use CPUminer with services as Betarig!
I'm getting right away a virus warning tho with this version, I'm not getting it with previous version.
Virus warning is common with mining software. |
