Here's their 39c3 talk about Xous: https://media.ccc.de/v/39c3-xous-a-pure-rust-rethink-of-the-...

The talk is great. Good into to Xous, to using the MMU sort of to do a rust borrow-checked owned memory system.

Also Bunnie talks about making the Baochip: a 1+4 small-tiny risc-v design. That hitchhikes on another company's core! "Can I also put fuses on so we can use this as a risc-v design?" "Sure"! So awesome!!
