How to mine with gridseeds and a raspberry pi.

[demonmaestro]

I want to know how and alot of people want to know how.
a nice and easy guide.

I will just stick this here for quick reference for people to get there gridseed miners up and going quick.

Ok, so first things first, disclaimer, I'm not a Linux guy, so please forgive me if I'm making a dumb mistake here.  I've also never used bgfminer so I've got that working against me as well.  

Thanks to everyone who helped me figure this out...here's a revised version of how to compile bfgminer for a RasPi...

------------------------------------------------
Steps I took to build BFGMiner from source:
------------------------------------------------

//update my RasPi first

Code:

sudo apt-get update

//saw this on the linux build instructions, so I presume I need these as pre-requisites to compiling bfgminer

Code:

sudo apt-get install build-essential autoconf automake libtool pkg-config libcurl4-gnutls-dev 

sudo apt-get install libjansson-dev uthash-dev libncurses5-dev libudev-dev libusb-1.0-0-dev libevent-dev

//cloned nwoolls version of bfgminer which has beta support for the miners in question

Code:

git clone -b feature/gridseed-support https://github.com/nwoolls/bfgminer

//build it

Code:

cd bfgminer

./autogen.sh

./configure CFLAGS="-O3" --enable-scrypt --enable-gridseed

make

sudo make install

sudo ldconfig

sudo nano bfgminer.conf 

//make the bfgminer.conf file.

Code:

{
"pools" : [
        {
                "name" : "MyPool1",
                "url" : "stratum+tcp://mypool.url.com:3333",
                "user" : "myworker",
                "pass" : "x",
                "pool-priority" : "0"
        }
],
"api-allow" : "W:127.0.0.1,192.168.1/24",
"api-listen" : true
}

//trying to run it

Code:

sudo ./bfgminer -S gridseed:all --set-device gridseed:clock=850 --failover-only --scrypt -c bfgminer.conf

I got pointed to this.

Look at main OP.

[richmke]

For the new Rasp Pi newbies, you may want to add the step one of loading the OS onto the Pi, and ssh into the Pi.

[demonmaestro]

You dont have to use SSH but if you want to you can.

and also you can use screen

[richmke]

My point is: are you using Scripta, Raspbian, Pidora, RaspBMC, OpenELEC, RSIC OS, Arch, or something else.

[demonmaestro]

raspbian..

[surgexvb]

is bfgminer stable with the 5 chip gridseeds yet?  I have yet to find something as stable as running individual cpuminer threads.

[demonmaestro]

well i have been mining on mine since sunday with no issues so far.

What's the best from your point of view to use to mine?

[demonmaestro]

i like raspbian

[sudoku]

Thanks for the tips. Will try the instructions when my gridseed arrive.

[Monkeyseemonkeydo]

What does make Raspian the best forum? What's the plus?

I want to mine scrypt and sha-256 at pool https://www.megamultipool.com/pools.php by using Gridseed:
stratum+tcp://east-us.megamultipool.com:3354
stratum+tcp://east-us.megamultipool.com:5000

So, how I configure Raspberry Pi? Any help please...!

well follow whats up top and put in your pool into the bfgminer.conf

Ok just installed BFGminer it runs pretty good but it only detects one device?

[demonmaestro]

have you rebooted the pi?

Also how do you have them connected?

[forevernoob]

I'm not using a pi for this.
cgminer works but the performance isn't fantastic and it's unstable.
So wanted to try BFGminer...

In cgminer I have GSD 0, 1 and 2.
I have them connected to a USB hub and only GSD 0 comes up in BFGminer.

To get them all to run in cgminer I have to manully point it in "the right direction".

Code:

sudo ./cgminer --gridseed-options=baud=115200,freq=1000,chips=5,modules=1,usefifo=0,btc=16 --hotplug=0 -o stratum+tcp://eu.multipool.us:7777 -u  -p  --usb 001:019,001:020,001:021

Is there a similar option in BFGminer perhaps?

bfgminer uses -S gridseed:all

what kind of hub are you using?

[PondSea]

pi@raspberrypi ~/bfgminer $ sudo ./bfgminer -S gridseed:all --set-device gridseed:clock=850 --failover-only --scrypt -c bfgminer.conf
 [2014-04-09 08:40:22] ./bfgminer: -c: JSON decode of file 'bfgminer.conf' failed
 unable to open bfgminer.conf: No such file or directory


Im getting this after doing all the steps?


Maybe add to the steps how to create the file.

pico bfgminer.conf

Then the config
