And if your Pi is failing to communicate with your Antminer U3 via cgminer, unplug and reconnect the USB cable. You can also SSH into your Pi at any time and run sudo screen -x cgminer to view your cgminer screen. You can play around with voltage and frequencies by following the table in the official manual, found here, there's no real need to change what I suggested above though. My Antminer U3 is running at around ~59-60Gh/s, hopefully yours should be the same. cgminer -bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD -bmsc-voltage 0800 -bmsc-freq 1286 Sudo nano /etc/rc.local - remember, Ctrl-X to exit, then type Y and press Enter to save changes.Īdd this just above exit 0, again enter your own pool, username and password: Now, add cgminer to start automatically when the Pi is powered on and create a screen session: Test cgminer is working correctly by running the following (input your own pool, username and password): Install, configure and also enable bmsc options:Įxport LIBCURL_CFLAGS=’-I/usr/include/curl’ 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 screen Login via PuTTY with the default username/password, then raspi-config if you would like to change the hostname, default password and so on. Run a fresh install of Raspbian using NOOBS, after the install type ifconfig and make a note of the IP address, so that you can remotely SSH into your Pi. That link is useless if you're running an Antminer U3, here's how I got mine working using screen and PuTTY.
