It should not be riscv, but rather riscv32 or riscv64.
c18 should also work as long as you have a GCC/clang version that actually supports that std. What is your version?
while we type this command ( ./gsd_butterstick.py --uart-name=crossover --with-etherbone --csr-csv=csr.csv --build --load ) we getting the error as:
