I have been working on an open-source automotive controller that can run TockOS (embedded operating system written in Rust).

The rough overview is on my X post here: https://x.com/BobAdamsEE/status/1965573686884434278

It's a long running process, and the HW is mostly defined (but not laid out) but on pause while I work on porting TockOS to an ATSAMV71 to make sure I won't run into any project ending issues with the SW before I build the hardware.
