Fedora/RISC-V should run on the lowRISC chips, but probably won't ever work on the embedded ones. We're targeting RV64G (64 bit RISC-V, with general purpose extensions) and given that it's a Linux server/desktop environment it also requires a fair amount of RAM.
We're not building any 32 bit binaries at all.
just. awesome. (+1 on no 32 bit).
looking forward to playing with this when you are ready.
