How to build flash and use examples on Windows with MSY2/MINGW64 shell

Download open source GCC RISC-V v12.2.0 from https://github.com/hydrausb3/riscv-none-elf-gcc-xpack/releases
- Extract the archive
Download MounRiver_Studio_Community_Win_V130.zip
- MounRiver_Studio_Community_Win_V130.zip sha256 shall be equal to 2d0f24426841ab01d7912c0a732c74c1aca24bf77c6ad580f3ae6d6b513c53bb
- Extract and Install it
Install MSYS2/MINGW64
- Follow all the steps including "Now MSYS2 is ready for you. You will probably want to install some tools and the mingw-w64 GCC to start compiling:"
  - pacman -S --needed base-devel mingw-w64-x86_64-toolchain git

cd ~
git clone --recursive https://github.com/hydrausb3/hydrausb3_fw.git

Start mingw64
Add the path to "GCC RISC-V v12.2.0" (example with nomultilib version xpack-riscv-none-elf-gcc-12.2.0-1-win32-x64.zip extracted in c: and renamed xpack-riscv-none-elf-gcc-12.2.0-1-win32-x64_wch_nomultilib) bin directory
- PATH="/c/xpack-riscv-none-elf-gcc-12.2.0-1-win32-x64_wch_nomultilib/bin/":$PATH
Change current directory to firmware example (here HydraUSB3_Blink_ULED)
- cd ~/hydrausb3_fw/HydraUSB3_Blink_ULED
Clean and build the firmware example
- make clean all
The flashable firmware with wch-ch56x-isp (*.bin) is available in ~/hydrausb3_fw/HydraUSB3_Blink_ULED/build/HydraUSB3_Blink_ULED.bin

Start mingw64
Add the path to "RISC-V Embedded GCC" bin directory
- For MounRiver Studio Community Win V130(or more)
  - PATH="/c/MounRiver/MRS_Community/toolchain/RISC-V Embedded GCC/bin/":$PATH
Change current directory to firmware example (here HydraUSB3_Blink_ULED)
- cd ~/hydrausb3_fw/HydraUSB3_Blink_ULED
Clean and build the firmware example
- make clean all
The flashable firmware with wch-ch56x-isp (*.bin) is available in ~/hydrausb3_fw/HydraUSB3_Blink_ULED/build/HydraUSB3_Blink_ULED.bin
