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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 3.4.0 works great on RPi and BE, and arch is a better choice.

As I saw the LCD module in adafruit with raspbian seems nice ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 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_Archhttps://github.com/kanoi/cgminer-binaries/tree/master/RPi_RaspbianMinepeon 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=87Regarding 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/cgminerLCDStatsI have 2 of these running that python code. One connected to an RPi and one to my desktop ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) ![](https://ip.bitcointalk.org/?u=http%3A%2F%2F198.245.60.111%2FPix%2F20130826102650RPiLCD.jpg&t=665&c=sYYD_NTEDmy4MA) 3 AMUs soloing ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) (AsicMinerUSBs) (Plus 1 ICA)

Thanks, Kano. Let me get my rpi and program it ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) 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?

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 ![Sad](https://bitcointalk.org/Smileys/default/sad.gif) 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. ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) M

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? 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 #!/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) * * * * * /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?

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

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.

With 3.4.0 do you still suggest arch is better option? Or both are the same? 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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif)

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 ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) Great job guys! Thanks.
