Wow!! Thank you very much xgtele!!! Cheers! Is a pleasure to help nice people!!

jafc76, I figured this by myself reviewing readme file for cgminer
That's why I deleted my post. Thank you for you help!

PS: by the way, a glass of refreshing beer is sent to your btc address  Thanks again for your useful post!

Xgtele, here the master is ckolivas but if you wanna use the erupters, change:

./configure --enable-bflsc

For

./configure --enable-icarus

I don't have any erupter but if I'm not wrong, with that should work

You are providing instructions from CGMINER 3.1.1

The opening post uses the current cgminer from git WHICH DOES NOT USE ttyUSB

Don't confuse instructions from different versions please.

Wow Server! Thank you very much! You are the first person that paid a beer!!

Cheers!! Glad to find nice people like you!!

This is a good motivation to add a few things to the tutorial like the watchdog and permissions to the user to access the plugdev group.

Thanks again!

Thanks man, great tut!

Cheers ;-)

Awesome tutorial! I learned a lot 

doesn't this 8 spaces password limitation make it vulnerable to hackers?

Great tutorial. Thanks for putting it together   


Everything went smooth until this bit. When I reboot, cgminer won't start automatically. I'm using cgminer 3.1.1 with Erupter USBs. Might the older cgminer be why it doesn't work?

Anyway, I wrote this script with nano, called it auto_cgminer, and saved it in my 'code' folder,


then entered

 @/usr/bin/lxterminal --geometry=90x35 -e code/auto_cgminer

in stead of

 @/usr/bin/lxterminal --geometry=90x35 -e cgminer

into the /etc/xdg/lxsession/LXDE/autostart file. Now it gets mining straight away to config file specs on startup.


Now here I got stuck:

I installed TightVNC onto my Ubuntu 11.10 computer, just as I had done as instructed here for the Pi. Then I don't know how to start it up so that I can do the second step, "Write your Raspberry Pi IP". Entering tightvnc or tightvncserver into terminal don't give me an option to enter the Pi's IP... What did I miss?

Followed all the steps, until now the best tutorial about "Wi-Pi Mining" I read.


should add:

- vncwiever pwd is truncated to EIGHT places. I was hammering away my usual 20-digit pwd.
- followed all the steps, didn't work so far. probably something with my router which blocks prettey much everything. maybe include the Pi as a hotspot/wifi repeater as well?


where is this --> '   character on the us keyboard layout?

Cool. Thanks for your sharing.
I want to use Raspberry Pi to control my blade.
It also should be possible.

in terminal:

cd cgminer
  git pull
       ./autogen.sh
       export LIBCURL_CFLAGS='-I/usr/include/curl'
        export LIBCURL_LIBS='-L/usr/lib -lcurl'
       ./configure --enable-bflsc
        make
        sudo make install

How to update New cgminer ?

thx

If you are using an Icarus FPGA, don't forget to configure CGMiner (Step 10 of the tutorial) with:   ./configure --enable-icarus




Can you explain the steps? Would be nice if I can try that.

i personally prefer not using the gui. its a system hog

using "screen" command in console allows me to access the bfgminer thats running behind the scenes without stopping anything.

and cacti allows me to see charts via web

Q: On linux I can see the /dev/ttyUSB* devices for my Icarus FPGAs, but
cgminer can't mine on them

A: Make sure you have the required priviledges to access the /dev/ttyUSB* devices:

 sudo ls -las /dev/ttyUSB*
will give output like:
 0 crw-rw---- 1 root dialout 188, 0 2012-09-11 13:49 /dev/ttyUSB0

This means your account must have the group 'dialout' or root privileges

To permanently give your account the 'dialout' group:
 sudo usermod -G dialout -a `whoami`
Then logout and back in again

If you follow all the steps I wrote should work well.

Do you have something connected to mine?

Please help me, thank you!

You can find that information here:

http://elinux.org/RPi_Easy_SD_Card_Setup

So I think that's not necessary.

I'm waiting an ASIC too.

Awesome job, thank you.
My RaspberryPi is already configured and waiting for its ASIC to come...

One small suggestion - to make the guide even more clear you could add two initial steps of SD card formatting and saving the image file to it.
