Off the top of my head, I don't know of any good books or tutorials. When I was working on this full-time, there wasn't a good way to learn in a comprehensive manner. Some instructions were incredibly unclear even looking at the specification. If you were familiar with other RISC assembly, I think making a simple project using RARS (or other simulator) would be a pretty good way to get a baseline understanding. Compiling C applications to risc-v assembly can also be helpful.
