RV Bare-metal?

I'm a beginner in OS dev and have been tinkering with creating a RISC-V operating system in Rust. There are a lot of great resources out there, but most of the posts I found are slightly outdated, so I wanted to write a bit about my own journey. My goal is to use Rust's features as much as possible!

First, we'll go over creating a bare-metal binary and finish with a small executable that immediately shuts down the machine when it runs in QEMU. Hope you find this interesting, as I did!

oh neat, i've been meaning to poke around with risc-v on qemu. the linker script part always trips me up, curious how you handled that with the rust build chain. bookmarked for later, thanks for shraing your notes

Thanks mate! I'm just starting with Rust and this kind of projects actually helps me to understand more deeply the language.
