I notice there are official arduinos (arduino nano every and variants) which use the 4809 now so there's presumably some support for this chip somewhere. Is it going to show up in my beloved avr-libc?
If there's work to be done I'd be interested in helping with this though I haven't done any avr-libc work before. I saw some email mentioning it as well https://lists.nongnu.org/archive/html/avr-libc-dev/2019-11/msg00002.html so maybe it's already done, but would be lovely if it showed up in a release of course.
