##building RISC-V from scratch, using Linux or WSL

sudo apt-get update sudo apt-get install autoconf automake autotools-dev curl python3 python3-pip libmpc-dev libmpfr-dev libgmp-dev gawk build-essential bison flex texinfo gperf libtool patchutils bc zlib1g-dev libexpat-dev ninja-build git cmake libglib2.0-dev git clone https://github.com/riscv/riscv-gnu-toolchain cd riscv-gnu-toolchain/ mkdir build/ cd build sudo mkdir /opt/riscv32im sudo chown $USER /opt/riscv32im ./configure --with-arch=rv32im --prefix=/opt/riscv32im make -j$(nproc)

For other architectures or variations of RISC-V

./configure --with-arch=rv32i /opt/riscv32i/ --> for RV32I ./configure --with-arch=rv32ic /opt/riscv32ic/ --> for RV32IC ./configure --with-arch=rv32im /opt/riscv32im/ --> forRV32IM ./configure --with-arch=rv32imc /opt/riscv32imc/--> for RV32IMC

windows precompiled https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/ for mingw64 other precompiled windows and linux toolchain for riscv https://gnutoolchains.com/risc-v/

Build the firmware

git clone https://gitea.squirrelnut.synology.me:5001/FPGALover/RISCV_picorv32_fpga cd RISCV_picorv32_fpga/sw make clean make firmware/firmware.fpga cp firmware/Memory.v_toplevel_memory_1_symbol* ../rtl/DE0-NANO

Now you can compile or synthesize the FPGA harware using Quartus or any other Design tool
