neorv32
neorv32 with modiefied Makefiles, compatible with MSYS2 64 for cross compilatation on Windows and Linux.
1. Windows Installation, and test.
2. Linux Installation, and test.
1. Windows Installation
You must download the latest RISCV precompiled binaries for your platform from: https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/
in this case the architecture x64 for windows binaries(https://github.com/xpack-dev-tools/riscv-none-elf-gcc-xpack/releases/download/v13.2.0-2/xpack-riscv-none-elf-gcc-13.2.0-2-darwin-x64.tar.gz), then extract these under the folder C:\riscv_precompiled
-
clone or download this repository on your windows machine.
$ git clone https://gitea.squirrelnut.synology.me:5001/FPGALover/neorv32 -
download and install MSYS2(msys2-x86_64-20240113.exe) --> https://www.msys2.org/
-
once MSYS2 is installed, run MSYS2, and run the command(pacman -S mingw-w64-ucrt-x86_64-gcc)
$ pacman -S mingw-w64-ucrt-x86_64-gcc -

[Y/n] [... downloading and installation continues ...] -
after the installation is completed, add the Path "C:\msys64\ucrt64\bin" under the enviroments variable on Windows.
-
open a cmd and run the command (gcc --version)
$ gcc --version gcc.exe (Rev2, Built by MSYS2 project) 13.2.0 -
go to the folder C:\msys64\ucrt64\bin make a copy of the file mingw32-make.exe and name it make.exe
-
go to the directory where you cloned or donwloaded this repository to the directory neorv32\sw\example\demo_blink_led_asm
$ cd neorv32\sw\example\demo_blink_led_asm -
run the command make all (make sure all antivirus are disabled)
$ make all "Memory utilization:" text data bss dec hex filename 432 0 0 432 1b0 main.elf "Generationg APP BIN" "OK - APP BIN" "Generationg APP IMG VHD" "OK - APP IMG VHD" "Generationg RAW HEX" "OK - RAW HEX" "Generationg RAW BIN" "OK - RAW BIN" "Generationg BOOT IMG VHD" "OK - BOOT IMG VHD" "Memories Generated" -
list the generated files and you will see
$ ls -l -rw-rw-rw- 1 adriz 0 6781 2024-02-24 01:45 main.asm -rw-rw-rw- 1 adriz 0 432 2024-02-24 01:45 main.bin -rw-rw-rw- 1 adriz 0 8708 2024-02-24 01:45 main.elf -rw-rw-rw- 1 adriz 0 5456 2024-02-23 16:14 main.S -rw-rw-rw- 1 adriz 0 2764 2024-02-24 01:45 main.S.o -rw-rw-rw- 1 adriz 0 274 2024-02-24 01:16 makefile -rw-rw-rw- 1 adriz 0 1882 2024-02-24 01:45 neorv32_application_image.vhd -rw-rw-rw- 1 adriz 0 1878 2024-02-24 01:45 neorv32_bootloader_image.vhd -rw-rw-rw- 1 adriz 0 444 2024-02-24 01:45 neorv32_exe.bin -rw-rw-rw- 1 adriz 0 432 2024-02-24 01:45 neorv32_raw_exe.bin -rw-rw-rw- 1 adriz 0 972 2024-02-24 01:45 neorv32_raw_exe.hex -
you have been able to Assemble assembly code for the RISCV on windows.
-
go con the folder neorv32\sw\example\demo_blink_led which is the same example as the previous one but written on C code., and run the line "make all"
$ make all
"Memory utilization:"
text data bss dec hex filename
1092 0 0 1092 444 main.elf
"Generationg APP BIN"
"OK - APP BIN"
"Generationg APP IMG VHD"
"OK - APP IMG VHD"
"Generationg RAW HEX"
"OK - RAW HEX"
"Generationg RAW BIN"
"OK - RAW BIN"
"Generationg BOOT IMG VHD"
"OK - BOOT IMG VHD"
"Memories Generated"
- now you have cross-compiled sucessfuly on windows for C and Assembly code.
- if you go to the folder neorv32\sw\example, and run the command "make all" you will be able to build all the projects within this folder.
Enjoy!

now you have been able to compile C code for the RISCV processor.
Enjoy!
