This script will convert your $35 Raspberry Pi and enable it to work as:
1. A host for your all your ASIC's and FPGA's
2. A Litecoin CPU miner that for me generated 20 shares on Netcode Pool in 10 hours
This script will not remove anything from your Pi!
Setup:
1. Make sure SSH access is enabled on your Pi. If not, run raspi-config and go to the advanced options.
2. Log in via SSH and type in the following:
3. Paste the contents of the file into the window, and then press Ctrl+X. Press y, and then press enter.
4. From wherever (SSH or the Pi itself), type in the following commands:
sudo chmod +x /usr/bin/setup
setup
And the script will let your Pi be a (headless) Bitcoin mining host and Litecoin CPU miner.
To mine litecoins using the CPU, type in the following command from anywhere, substituting yourpool, port, username, and password:
minerd --url
http://yourpool:port --userpass username:password
or for Stratum:
minerd --url stratum+tcp://yourpool:port --userpass username:password
To use your FPGA or ASIC, type in the following command from anywhere, substituting yourpool, port, username, and password:
sudo bfgminer -o
http://yourpool:port -u username -p password
or for Stratum:
sudo bfgminer -o stratum+tcp://yourpool:port -u username -p password
Sudo is necessary for bfgminer to save your configuration.
Pooler's CPU miner has been built, installed, and used successfully testing this script in QEMU.
FAQ:
Q: My Icarus or other USB-powered miner won't power up!
A: You will need a powered USB hub. The Pi's USB ports (at 140mA each) can barely power a keyboard and mouse, they can't power your miner.
Q: Why can't you just compile BFGminer with scrypt and CPU support?
A: BFGminer specializes in ASIC's and FPGA's, not CPU mining. Pooler's CPU miner is very optimized for it.
Q: Why can't I mine Litecoins with my FPGA or ASIC miner?
A: There are no scrypt-compatible FPGA's or ASIC's (though they can be made).
Q: How do I exit the miner and power off the Pi?
A: Press Ctrl+C and type in
sudo poweroff
You can safely unplug the Pi once the TV says "No Signal".
Q: I really want to mine bitcoins using the CPU!!!!!!!
A: Add --algo sha256d to the minerd flags.
Q: I don't want to see the hashrate display.
A: Add -q to the cpuminer flags. Don't worry - the miner will display the hashrate only when a share is submitted.
Q: I want more performance for Litecoin mining!
A: Edit your config.txt using Windows (or /boot/config.txt on other OS's) and increase the values to the following:
arm_freq=1000
sdram_freq=500
core_freq=500
And add the following line: over_voltage=6
Expect 0.48 khash/s.
Q: What happened to the image?
A: It took a while to make it, put it in a zip, and upload it, even just for installing one package. Updating the script is much easier to do.
