Install a Gridseed dual miner on Linux/Raspberry Pi

To use Script mining (LTC) with usb Gridseed dual miner GC3355 in Ubuntu 14.04 you can use a specific version of cpuminer.

Step 1: " sudo apt-get install build-essential libtool libcurl4-openssl-dev libncurses5-dev libudev-dev autoconf automake "

Then use git to download the specific version of cpuminer.

Step 2: " git clone https://github.com/gridseed/usb-miner "

Go to subdirectory

Step 3: " cd usb-miner/software/cpuminer "

start compiling...

Step 4: " ./autogen.sh "

Step 5: " ./configure "

Step 6: " make "

Now we have to check the “name” of usb miner. It should look like ttyACMx or ttyUSBx

To find dual miner name you can use lsusb and/or dmesg.

Step 7: " dmesg | grep STM32 "

root@raspberrypi:~$ dmesg | grep "8-2"

In this case the dual miner GC3355 is ttyACM0 ....

The base command to start miner is....

" miner -G /dev/ttyACM0 --url=yourpoolurl:port --userpass=yourusername.worker "

This is the general command for cpuminer

To change frequencies use parameters –freq= . Don’t exceed freq=850 MHz. It’s dangerous.

Step 8: " sudo ./minerd --freq=600 -G /dev/ttyACMx(x=Number for device) [if more then one miner write -G before each] --url=yourpoolurl:port --userpass=your_username.your_worker:passwordworker "
