RandomX XMRig Mining on Raspberry Pi

Hey all,

I've read a lot of people posting on various Monero forums wanting to mine Monero on the Raspberry Pi, or other ARM SBC's. Out of curiosity, I decided to compile a release on XMRig for the Pi, and while the performance wasn't great, (15-20 H/s) running in RandomX "light mode", I figured it wouldn't hurt to post a tutorial on how to do this, and perhaps others could improve on my work!

In order to mine on the raspberry pi, you need to have a chroot environment set up, so that you can use aarch64 applications, such as XMRig. If setting up a chroot and compiling the software isn't something you want to spend time doing, simply download my pre-built raspberry pi image, and flash it to a 16GB card. It has ssh enabled (default password raspberry), and will auto load a chroot with xmrig, simply run ./xmrig --help to see the available options.

You can create this chroot by running the below commands, modified from this XMRig issues post.

sudo apt install -y debootstrap schroot
cat << EOF | sudo tee /etc/schroot/chroot.d/pi64
[pi64]
description=VC4 arm64 testing
type=directory
directory=/srv/chroot/pi64
users=pi
root-groups=root
profile=desktop
personality=linux
preserve-environment=true
EOF
sudo debootstrap --arch arm64 stable /srv/chroot/pi64
sudo schroot -c pi64 -- apt install -y sudo gcc libssl-dev libuv1-dev libnuma-dev libhwloc-dev cmake

From there, you can run schroot -c pi64 to enter your new chroot environment, which can now support the compilation and running of 64-bit programs like XMRig!

Once we're in the chroot environment, we pretty closely follow the build process on the official XMRig github. Simply run these commands in the new chroot environment to build a copy of XMRig.

sudo apt-get install git build-essential cmake libuv1-dev libssl-dev libhwloc-dev git clone https://github.com/xmrig/xmrig.git cd xmrig && mkdir build && cd build cmake .. make

Now, you have a fully working XMRig binary in the build directory, which you can use to mine Monero, Dero, or anything else! Leave a comment if you have any questions, or if you have another ARM board/mining software that you would like to see a tutorial for. I plan on doing a whole series of these, so if there's anything in particular you want to see, please recommend it. In addition, if you either are willing to donate a board, or donate enough for me to buy a specific board, I'll put it at the front of my priority queue to do a post on!
