The issue was that there wasn't a cheap riscv board that supported the privileged section of the ISA (so you can run an OS on it). This, being a microcontroller, doesn't either.

The Reference Manual claims "Machine (M) and User (U) Privilege levels support" on page 22.

Probably not the kind of privileges discussed yesterday.
