I have read the adfruit guide with an lcd screen ansd tried to modify it to work via ssh only but can not get my block eruptors mining. This is what I do:
Or to delete the download and start again with the make while in the topmost cgminer directory
This will delete the entire directory
cd ..
then type rm -rf /cgminer-3.1.1
You probably have all the files but start here anyway
sudo apt-get install libusb-1.0-0-dev libusb-1.0-0 libcurl4-openssl-dev libncurses5-dev libudev-dev
wget
http://ck.kolivas.org/apps/cgminer/3.1/ ... .1.tar.bz2 2 & 3!!
tar xvf cgminer-3.1.1.tar.bz2
cd cgminer-3.1.1
./configure --enable-icarus
make
Crucial to look for any errors after the config and then after you run make
We can now test it with
export DISPLAY=:0
./cgminer SEE BELOW 1 if nothing
It won't work but it should say can't find any usb devices then continue on by making the conf file and run the last command.
sudo nano cgminer.conf
stratum.bitcoin.cz:3333
.worker1
password
copy the file in and put in your settings now ready to run
./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 -S /dev/ttyUSB1 >/dev/null 2>&1&
troubleshouting
dmesg | grep -i usb
dmesg | grep -i tty
Those two should show a lot of info maybe copy it all into a doc. Run one and look over the lines for anything suspicious like failures, etc then do the same for tty.
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 see what groups an account has
groups <username>
To permanently give your account the 'dialout' group:
sudo usermod -G dialout -a `whoami`
Then logout and back in again
1. The first part
./cgminer
It doesn't show any errors? I can't figure out what it's doing it should return something.
You can type
ps aux | grep cgminer
As seen in this pic
the second line root 4097, root 4098 look for a line that has cgminer at the end (example shows python Piminer.py look in that spot for cgminer)
Like this one
After root is the PID use this line to kill cgminer if it is running
sudo kill 4097
In the first example PiMiner.py is running under the PID of 4097 find the PID of cgminer and kill it.
Also the instructions do show that the conf file is not in the cgminer directory you point to it in the run line
--config /home/pi/cgminer.conf
I missed that part (they do make good tutorials but if you skip a line it's can get messy it seems like you followed it word for word but are getting something not expected)
2.
wget
http://ck.kolivas.org/apps/cgminer/3.1/ ... .1.tar.bz2
3. wget
http://ck.kolivas.org/apps/cgminer/3.1/ ... .1.tar.bz2
But everytime I try and run ./cgminer-3.1.1/cgminer --config /home/pi/cgminer.conf -S /dev/ttyUSB0 >/dev/null 2>&1&
Nothing happens apart from
[1] 2191
Does anyone have any ideas please
