Starting with tutorial 6, booting kernels on your Raspberry is getting really comfortable. In this tutorial, a so-called chainloader is developed, which will be the last file you need to manually copy on the SD card for a while. It will enable you to load the tutorial kernels during boot on demand over UART. The original version of the tutorials started out as a fork of Zoltan Baldaszti's awesome tutorials on bare metal programming on RPi3 in C.

This is it! You've built Rust code for bare metal arm that will run on the Raspberry Pi!

August 21, 2016 - My goal was to achieve that with as little assembly as possible, bringing all the cool stuff to Rust, and to my surprise, this was something fairly easy to achieve. To get started we’re going to need `arm-none-eabi` toolchain, for cross-compiling, Rust nightly with `libcore` compiled for this architecture, Raspberry’s boot files and a Raspberry Pi B+ to run our code.

Looks to me that if you take the bare metal Rust you will have a lot of work to do to get it running on the Pi. Presumably there is no run time support, no drivers for any peripheral hardware etc, etc, You would effectively have to write a mini OS for yourself to get it running.

February 21, 2025 - Hello, I am as you can see an absolute newcomer to Rust and did not find any helpful information on whether I can compile Rust code bare metal for a RaspberryPi 4b. I want to do this because I want to build an operatin…

This repository contains different tutorials that provide an easy to follow guide to get started with the development of Rust bare metal systems for the Raspberry Pi.

Tue Nov 08, 2022 7:57 pm thats an aarch64 binary, but the pi-zero is armv6 only rustc doesn't support any targets for armv6, actually, so I'm currently following https://wiki.osdev.org/Raspberry_Pi_Bare_Bones_Rust, maybe it'll work...

Hi all. This repository aims to provide easy reference code for programming bare metal on the Raspberry Pi 3 in the Rust systems programming language.

January 19, 2016 - Yes, and that is unsafe. Rust makes you put that in an unsafe block, to encourage you to build safe interfaces. This is a good thing · The alternative to name mangling is not having a module system, with all the fun name conflict issues that come with it. Rust made the right decision here

I am working on bare metal programming for a Raspberry Pi 3. I have been able to blink a light using a tutorial and I am now trying to do the same in Rust. My project contains the following files:...

An experiment in bare metal programming the Raspberry Pi using Rust - csgero/picrust

August 13, 2023 - I chose not to focus on making it work there because my previous experiences have shown that QEMU's emulation of the Raspberry Pi may not always be entirely accurate. As in, even if the project runs well on QEMU, it might not perform as expected on the actual hardware. Well, this has been fun! This project is a side project out of an operating system I've been writing on the side for a while. As part of that, I've also written and released a vfat driver. In this project, I've implemented a Space Invaders on bare metal in Rust.

October 2, 2020 - What does he mean by this? Rust has no-std mode, you can run it on an ARM M0 if you so desire · That said, nobody is obligated to use Rust. He should write his tutorial in whatever he wants. This isn't an actual blocker, though

September 26, 2024 - My goal was to achieve that with as little assembly as possible, bringing all the cool stuff to Rust, and to my surprise, this was something fairly easy to achieve. To get started we’re going to need arm-none-eabi toolchain, for cross-compiling, Rust nightly with libcore compiled for this architecture, Raspberry’s boot files and a Raspberry Pi B+ to run our code.

Fortunately, @swarren has not only been working on u-boot for the 3B, but also some other "bare metal" odds and ends. The one that I really needed was this: a dead-simple demo of serial I/O on the 3B (the 64/ folder contains the code I used). Once I got that working, I felt like I was ready to jump back into the Rust part of things.

January 20, 2026 - "We want to compile code for a ... "We also want to use it bare metal which means we don't want it to run on an existing operating system so we can't use existing OS libraries."...

The whole discussion and enable code is nonsense there is no such thing as AARCH64 soft floats the GCC standard is AAPCS64 You don't have a choice of under AARCH64 AAARCH64 call convention floats VFP/SIMD mandatory - no soft float ABI V0 - V7 arguments and return value D8 - D15 callee saved registers V16 - V31 temporary registers Bits 64:128 not saved on V8-V15 For a more complete look at AAARCH64 Conventions http://shervinemami.info/arm64bit.html The coprocessor starts on but only accessible from EL2 and EL3 The reason it will be locking up is because you will be in EL1 or EL0 with the coprocessor access off In baremetal we usually grant generic EL0, EL1 to the co-proccessor at startup while in EL2 something like

January 16, 2016 - Yes, currently Rust depends on those to get any sort of decent performance.
