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!!
This was a really great talk. Full of interesting things. E.g. his BIO system for replacing Raspberry Pi's proprietary PIO. It uses RV32E (16 registers) and then uses x16-31 as custom registers to directly control the pins so you can do GPIO without the usual delays from MMIO.
Thanks, of all the discussion on this HN comment page, your link (without even having to watch the video) finally answered my question of what the intended purpose is of this OS.
