Introduction It’s been well over a year (perhaps almost two even) since I implemented this, so unfortunately I’ve already forgotton most of the story around it. However, I remember it was a huge struggle so I’ve been meaning to write it up for a while in the hope that it might help others in the future. It’s also just a nice reference for my future self :) Anyway, we’ve recently starting shipping a product powered by embedded Rust and Embassy! Embassy includes a great bootloader, but it was not easy to find a way to read the bootloader version from the application, so in this post I’ll briefly document how that was achieved. ...

Introduction As you might have noticed, Rust is already quite popular in the embedded space. And getting started with embedded Rust, even on a bare-metal level, isn’t all that difficult. However, I’m not a fan of the standard method as it has a bit too much magic for me. When it comes to embedded, I like to know exactly what is going on and that includes knowing the very first code which is run and “kicks off” the main code. As such, I have explored how to do this for the STM32F4-Discovery using C code which then fires up a Rust main function. In this blog post, I will give an overview of the process that I followed. ...
