OFFICIAL CGMINER mining software thread for linux/win/osx/mips/arm/r-pi 4.11.1

[-ck]

Hi Kano, just got a quick question. With rpi and BE, does 3.4.0 works great on it? Or should go with an earlier version? And with the latest updates, should I go with arch or raspbian? As I saw the LCD module in adafruit with raspbian seems nice

3.4.0 works great on RPi and BE, and arch is a better choice.

Thanks, I will try to set it up. I did have a look already in Kano website. How do I add an auto start cgminer when power up the rpi and load a config?

I've not noticed any trouble with 3.4.0 however the biggest change between 3.4.0 and 3.3.4 is how the timing is done in cgminer so if you have any trouble with 3.4.0 try 3.3.4

I do have both an Arch and a Raspbian binary of both 3.3.4 and 3.4.0 in my cgminer binaries that is statically linked with the working libusb
https://github.com/kanoi/cgminer-binaries/tree/master/RPi_Arch
https://github.com/kanoi/cgminer-binaries/tree/master/RPi_Raspbian

Minepeon users have had some trouble with Arch in his latest release and that is as yet unresolved so I've no idea if that is related or not.

My bare bones install guide for Arch on RPi is here: http://www.kano-kun.net/?p=87

Regarding the LCD displays you can get for the RPi, there are 2 types.
1) A display that is simply just a screen for the RPi itself (I don't have one of these)
It works like any other screen (HDMI or A/V connectors) except smaller and needs drivers configured for it

2) USB LCD displays that can be used for displaying the cgminer stats
https://github.com/cardcomm/cgminerLCDStats

I have 2 of these running that python code.
One connected to an RPi and one to my desktop

3 AMUs soloing (AsicMinerUSBs)
(Plus 1 ICA)

Thanks, Kano. Let me get my rpi and program it very thanks for the sharing of the setup! And I gotta buy that cute USB LCD!

With 3.4.0 do you still suggest arch is better option? Or both are the same?

[mdude77]

And you know that how?  You know for certain some catastrophic event won't occur that'll drive the value of BTC to ridiculously low prices, causes people to abandon in droves causing difficulty to drop?  You also know they won't still be mining 10 years from now?  No moving parts, simple construction, if properly cooled they should last a while.  (That remains to be seen of course.)

M

I'd bet you 10BTC neither of those things will happen in the next 12 months ... except I can't afford to make the bet and tie up 10BTC for 12 months

I'm not a gambling man.  And 12 months is a far cry from your "never" statement.  He could also solo mine and get lucky and get a block.  Just pointing out your absolute statement could quite easily be wrong.

1. Install screen and pgrep
2. Create "cgminer" user (assume /home/cgminer is home directory for new cgminer user). On debian-based systems you probably need to add cgminer to the plugdev group ("adduser cgminer plugdev").
3. Login as cgminer user (possibly via "sudo su cgminer" etc)
4. Setup /home/cgminer/.cgminer/cgminer.conf
5. Test that running cgminer with no command line options does what you expect.
5. Create /home/cgminer/daemon.sh

Code:

#!/bin/bash

log () {
    logger -p local0.notice -t $1/daemon.sh "$*"
}

export HOME=$(dirname $(readlink -e $0))
cd $HOME

if ! pgrep -u cgminer cgminer >/dev/null; then
    log cgminer is dead
    screen -dmS cgminer $HOME/bin/cgminer
else
    log cgminer lives
fi

daemon.sh checks if the "cgminer" user is running a program called "cgminer". If so, then nothing happens. Otherwise it starts a new detached screen session running cgminer. You may have to adjust $HOME/bin/cgminer to your machine. (I use ./configure --prefix=/home/cgminer and make install so my cgminer binaries end up in /home/cgminer/bin/cgminer)

6. chmod +x /home/cgminer/daemon.sh
7. Add the following line to the crontab to run /home/cgminer/daemon.sh every minute (run "crontab -e" as cgminer to edit crontab)

Code:

* * * * * /home/cgminer/daemon.sh

In the future I'd like to add use of a chroot, but I haven't had time to work on that yet.

A quick question: how do I instruct cgminer to use only GPU and ignore all USBs?

A quick question: how do I instruct cgminer to use only GPU and ignore all USBs?

The README says that "--usb :0 will disable all USB I/O other than to initialise libusb".

[Nemo1024]

Thank you, and excuse my laziness.

Any idea how/why this happens?



The software works like a dream... and I love you for it.... so please don't take this as a complaint, just as a "I wonder if I'm using it incorrectly".

The GPS are hashing like MF'ers, and blocks fall before me... so why does it tell me 0% load?

cgminer only reports back whatever the driver tells it the load is. However the driver will report 0 if you query it too often. I don't know what front end you're using there to communicate with cgminer but perhaps that's all it is.

BAMT and the mgpumon tool.

Good to know.  Thanks.

I'm not sure why Minepeon has had trouble on Arch - so I don't know.
The original libusb problem didn't exist on Arch with that install I've used, but there is of course a simple workaround for Raspbian - use the libusb in the README (which I now use in all my binary builds)
I have had the rare network dropout occur on both Arch and Raspbian
At this point I'm using Arch for mining and Raspbian is the media player ... that's incomplete.
However I'll probably put an AMU in the media player soon just so it's running cgminer all the time rather than just testing when I build my binaries

Hi,

I was having a lot of messages in cgminer  "BTB: Idled X miners". When that happen my hash rate would go down by half. 3.4.0 resolved all the issues Great job guys! Thanks.

[Karin]

If you can build from git and you're on OSX, try building now as I've added a generic workaround for this.

Cool!  Thanks for doing this.  I get this when compiling now:

Code:

util.c: In function ‘cgtimer_time’:
util.c:1017: error: ‘ts’ undeclared (first use in this function)

Thanks. git pull and try again please (I'm coding blind!)

If I could buy you a Mac to help you test I would, but thanks for this nonetheless!  I built from the latest git and it errored with:

If you are interested in the entire compiling output, it produces a few Mac-specific warnings that don't seem to affect the program (these warnings have existed for a few versions now):

Perfect, that did it, and thank you!  I just sent you a very tiny bitcoin tip.  Don't even look at the value, seriously, it's so tiny (that's not sarcasm either).  But hey, good work should be recognized.

You're solo mining. Only a block solve would get accepted.

But in the earlier version was all good...
