    At the moment, I think the right balance to strike is to maintain a low level C BSP and link in Rust code on top.

    I admire what the Rust community is doing with embedded-hal, and I hope they eventually convince chip makers to contribute Rust BSPs using the standard API.

    Until then, you’re left relying with an unofficial BSP with no support whatsoever. This is a deal breaker for most organizations.
