Rust on the CH32V003

The process of porting Rust to the WinChipHead CH32V003 microcontroller. We start off by porting the Rust compiler itself to a new variant of RISC-V and then we go through the details of interfacing with out hardware on the lowest levels.

• Part 0: Introduction

  I have a new side project, and it involves porting Rust to an (almost) new platform. Let's meet our hero, the CH32V003

• Part 1: Custom Rust toolchain

  To make Rust work for our microcontroller, we first have to support RISC-V's E extension. We'll patch and build LLVM to generate correct code, and then fix a small issue in Rust itself

• Part 2: Boot and blink

  Armed with a functional Rust toolchain, let's work through setting up the core and interfacing with hardware. By the end we will have a blinking LED

• Part 3: The embedded ecosystem

  After getting a basic proof of concept implementation working, let's take a look at how the Rust embedded ecosystem works
