This guide walks you through each of the stages/prerequisites you need to get building and deploying an AVRoxide application on an Arduino Nano Every, with its ATmega4809 processor.

Commentary on the why for each of these steps is elsewhere on this site, so here we’ll stick to the What rather than the various Whys.

1. Pre-requisites for building Rust

First, install the various pre-requisites for building Rust:

• gcc-avr binutils-avr avr-libc wget lsb-release software-properties-common
• cmake
• ninja-build

These are the Ubuntu Linux package names - you will need equivalents for other operating systems, e.g. use homebrew to find the various apps for Mac.

2. Build a working Rust for AVR toolchain

git clone https://gitlab.com/snowgoonspub/rust-avr-nightly-builder
cd rust-avr-nightly-builder
./build.sh

You will now have a working version of nightly Rust for AVR, linked as a toolchain named snowgoons.

3. Install the official Microchip AVR toolchain

Currently located here on microchip.com, you want the AVR 8-bit Toolchain 3.6.2.

4. Install the other tools you need for your hardware device

At a minimum, you will need avrdude to flash your device.

5. Download a template application

git clone https://gitlab.com/snowgoonspub/avr-oxide-templates
cp -R avr-oxide-templates/atmega4809 my-new-application

6. Build and run

cd my-new-application
cargo run --release

And that, as they say, is that!
