See Tock OS https://www.tockos.org/ for another Rust-based embedded OS with a fairly comparable design to Hubris. The debugging capabilities of Humility make an interesting comparison to what's provided by cargo-embed https://probe.rs/docs/tools/cargo-embed/ and the Knurling Tools https://knurling.ferrous-systems.com/tools/ by Ferrous Systems.

Ultimately, the embedded space (including all sorts of low-level, retro, "bare-metal", remote etc. programming) has common needs and it would be convenient to see more widespread cooperation among these projects, improving reliability and avoiding wasteful duplication of work.
