Hi Nick, One of the common reasons you might see the error you are noticing is if you somehow end up using the host compiler instead of the RISC-V compiler. I will recommend that you verify that riscv toolchain directory is added to your $PATH. See this for reference: https://github.com/riscv-software-src/riscv-tools/issues/292
