Overview
To maximize your hashrate, it is very important that you select a 64-bit OS image, a quality miner and the most current compiler that you can.
OS Image
The 64-bit Ubuntu Server for Raspberry Pi3 is a good choice:
http://cdimage.ubuntu.com/releases/18.04/release/ubuntu-18.04.3-preinstalled-server-arm64+raspi3.img.xz
You will need to write this image to an SD card with a utility such as Etcher. Once your OS is written, insert your SD Card and boot your Pi.
Once you've got it booted, you'll be asked for a username and password. These are both
ubuntu
.Once you've logged in, you'll be asked to change the password. For the current password, enter
ubuntu
again. Then, enter a new password, and confirm it.Get the Latest Compiler
You will need to edit your sources.list file and add the debian testing repository in order to install gcc-8 and g++-8 on your system:
sudo nano /etc/apt/sources.list
Add this line to the end of the file:
deb http://ftp.us.debian.org/debian testing main contrib non-free
Then save it with
Ctrl-x
and then the following:sudo apt-get update
sudo apt-get install gcc-8 g++-8
Download Compile, and Configure Your Miner
Now you need to install the required dependencies and the latest release of the xmrig miner and compile it with gcc-8.
sudo apt-get install git build-essential cmake libuv1-dev libmicrohttpd-dev libssl-dev
git clone https://github.com/xmrig/xmrig.git
cd xmrig
sudo mkdir build
cd build
sudo cmake .. -DCMAKE_C_COMPILER=gcc-8 -DCMAKE_CXX_COMPILER=g++-8
sudo make -j4
Compiling the miner could take several minutes to complete. When your miner is ready you need to create a configuration file with your Kryptokrona settings. Navigate to your home directory and create a file named config.json.xkr.
cd ~
sudo nano config.json.xkr
Populate your configuration file with something similar to the code below. Make sure that
url
, user
, and pass
are populated with the your own unique and proper values.{
"algo": "cryptonight-pico/trtl",
"background": false,
"colors": true,
"retries": 5,
"retry-pause": 5,
"donate-level": 1,
"syslog": false,
"log-file": null,
"print-time": 60,
"av": 0,
"safe": false,
"max-cpu-usage": 100,
"cpu-priority": null,
"threads": null,
"pools": [
{
"url": "YOUR_POOL_URL_PLUS_PORT_GOES_HERE",
"user": "YOUR_TURTLE_ADDRESS_GOES_HERE",
"pass": "YOUR_MINER_NAME_GOES_HERE",
"keepalive": true,
"nicehash": false,
"variant": -1
}
]
}
Create a separate miner start script so that you can easily start the miner and invoke the proper cofiguration file with a single command. I like to name it "minexkr".
sudo nano minexkr
Place the following code into the minexkr file:
#!/bin/bash
sudo sysctl -w vm.nr_hugepages=8
~/xmrig/build/xmrig --config=config.json.trtl
Make the file executable as a script:
sudo chmod +x minexkr
Now you can start the miner using the start script:
./minexkr
Conclusion
Happy mining and make sure to support small pools and keep Kryptokrona mining decentralized.
