How to add cgminer 4.8.0 on pi raspbian

[peontky]

I am going crazy . I can't find any help about this issue. I got Raspbian but can't find out how to down load the antminer U3 drivers or CGminer 4.8.0. on my pi.

can someone link me to the right site or write the script need to get it in.

You need to call the emergency services, Google is broken in your part of the World.

That link is useless if you're running an Antminer U3, here's how I got mine working using screen and PuTTY.

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. Login via PuTTY with the default username/password, then raspi-config if you would like to change the hostname, default password and so on.

Now update the Pi:
sudo apt-get update
sudo apt-get upgrade

Install dependencies:
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

Clone cgminer from here:
git clone https://github.com/bitmaintech/cgminer

Install, configure and also enable bmsc options:
cd cgminer
sudo ./autogen.sh
export LIBCURL_CFLAGS=’-I/usr/include/curl’
sudo ./configure --enable-bmsc
sudo make

Test cgminer is working correctly by running the following (input your own pool, username and password):
sudo ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286

Type Q to exit cgminer...

Now, add cgminer to start automatically when the Pi is powered on and create a screen session:
sudo nano /etc/rc.local - remember, Ctrl-X to exit, then type Y and press Enter to save changes.
Add this just above exit 0, again enter your own pool, username and password:
cd /home/pi/cgminer
screen -dmS cgminer ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286

My Antminer U3 is running at around ~59-60Gh/s, hopefully yours should be the same. You can play around with voltage and frequencies by following the table in the official manual, found here http://bit.ly/1BMXNXL, there's no real need to change what I suggested above though. You can also SSH into your Pi at any time and run sudo screen -x cgminer to view your cgminer screen. And if your Pi is failing to communicate with your Antminer U3 via cgminer, unplug and reconnect the USB cable.

If you found this useful, I accept Bitcoin donations by following this link http://bit.ly/1GWElN4 ... Hope I helped!

Need some experiments with gcc "cflags".Linaro gcc better for performance when compared raspbian default gcc.

hi !
i have 4 g blade 5.2 MH , usb hub and i need help to run this in raspberry Pi 2 B . I try with bfgminer but not found usb device ,,M,, and + not work!
Thank you very much!

[definer]

This is the MOST straightforward discussion of how to install cgminer on a R-Pi that I've read. It worked FLAWLESSLY!!

[tommydark]

I succeed )) Thank you!

Hey, great news! Happy you both got things sorted

I'd like to thank you for your post. You made it extremely easy for me, who is brand new to raspberry pi, to get my miners up and running.

I'd like to add one side note related to an issue I ran into while running cgminer on my pi with the above command. It turned out that cgminer would crash/halt after a few minutes of hashing without notice or any error. So I did some digging and found the --lowmem option to be the fix. So i'm under the assumption that raspbian and/or the pi itself was killing the cgminer process due to excessive memory usage.

tl;dr: Thanks! Try adding --lowmem if cgminer keeps crashing during hashing.

Thanks kelten, good to hear you got it working too
I haven't had any memory issues, I'm wondering if its because you have a different model Pi compared to myself, I've got a Pi 2B which has 1GB RAM.

I followed this video

that follows this tutorial and everything worked smoothly... im working with slush's pool and using putty to conect to my pi.

all i see is this

the top isn't refreshing the hash rate so i dont know how its doing but the bottom (start nonce, start voltage, and start freq) part just keeps looping with different values.

and when i go to slushes pool dashbord it doenst say any of my workers are going.... also my ASIC Miner Block Erupters led is off but it was solid the whole time i was setting it up...

[charlie.us]

Good day

I'm new in linux and the terminal. When i close my ssh session (putty) the cgminer is stopped. how can i close ssh session and leave the cgminer working?

Thank you so much, and sorry for my noob question.

Another happy customer. I got my two U3 up and mining on PI with 119 avg.
ajweller88 - you wrote some of the best instructions and well defined steps I have ever seen. Great Job!

Sorry for the late reply, I don't really browse these forums, anyway... Could be a couple of things

• 1. Looks like your frequency is incorrect, or even try removing the frequency altogether to see if it automatically adjusts for you?
  2. You *may* need to clone cgminer from a different repository as this is for Bitmain miners only.

Another thing to note is that I've only tested this working 100% on the Antminer U3.

As "SonOfAMotherlessGoat" mentioned, you need to use screen to have it running in the background, I also suggest having your Pi start mining on boot to minimize potential downtime if your Pi restarts for whatever reason.

Awesome! Happy to hear you got it working and for your kind words

[troycopes]

What about connecting multiple Antminers to a Raspberry Pi after doing this for your first one? Will this command allow for, say, 4 miners to be connected to the Pi (2 model b) or will additional commands be needed to recognize each miner?

Also, do each miner need to be set up as their own workers for your chosen mining pool? Or will all hooked into one Pi be 1 miner?

[keithgagne]

For my setup, I have 2 Antminer U3 connected to the PI. No special command for multiple miners though I am not sure if there is an upper limit to the number of miners that can be attached. The PI/cgminer app detects the additional miner and adds it to the same pool, so I am getting 120-125 GH combined on the one pool worker. I believe I read about options for separating them into different pools, but I chose to keep it simple and no need to differentiate between the 2 miners.

[Jawsh]

Used the info here to setup 2 Pi 2s running Antminer U3s (2 on 1 and 1 on another)

I went ahead and reserved some IPs for the Pis so they quit changing on me, too...

One Pi is running off of a 12 volt battery connected to an inverter, directly off of the USB port on the inverter. The single U3 on it is currently powered by the grid, but not for long. It'll also be connected to that battery, once I have more panels up to support it.

The other is my dev environment with 2 U3s connected to a computer power supply, since the reseller didn't ship the power supplies with the U3s, but instead included a cable that connects to 6 pin 12v... Least the PSU only draws on demand.

Now they immediately start mining when they boot up and I can just remote in and open screen to see their activity.

Thanks ajweller88!

I got all the way unto "

"

I added my POOL, USERNAME and PASSWORD, but when I hit enter, putty gives me the following error, even though I am in the cgminer directory:

sudo: ./cgminer: command not found


What is the reason for this error? How can I fix it?

I would be soooo happy to understand it.

All the best,
mnk

[Jawsh]

Are you in the cgminer directory? If not... cd cgminer...

Guessing you probably didn't finish it up with "sudo make" or the configuration command that precedes it, though. After you do make, cgminer is executable

[mnk]

"sudo make" results in the following:

Part 1 of 2:


Part 2 of 2:



i am indeed in the cgminer directory but still am getting the same error (sudo: ./cgminer: command not found) when after "sudo make" entering the edited version of "cd /home/pi/cgminer
screen -dmS cgminer ./cgminer --bmsc-options 115200:0.57 -o POOL -u USERNAME -p PASSWORD --bmsc-voltage 0800 --bmsc-freq 1286".

any ideas how to fix it?

Thanks this helped so much!
