Thanks! It seems to work, here's the output I get when trying to run it directly:
I looked through the getting started guide I found on the RPI website but Appendix C only had instructions for setting up the ARM toolchain. At least as far as I found. There was no mention of RISC-V I was able to find in the PDF. I've been searching high and low for manual setup instructions because I like to know what all is involved in setting up the development environment, but have been unsuccessful.
