2.4 Install RV32M1 GNU GCC Toolchain
www.open-isa.org provides the pre-built GNU GCC toolchain for RV32M1 device. It’s the RISC-V C
and C++ cross-compiler and supports the Newlib library for use on the RV32M1-based embedded
system. Follow the steps below to set it up:
1.
Download the pre-build RV32M1 GNU Compiler toolchain from the www.open-isa.org website.
2. Unzip the downloaded package at the GNU MCU Eclipse folder created in the step 2.2 .
a) Although possible to install the toolchain in any folder, it’s recommended to install it under
D:\clipse\GNU MCU Eclipse folder for clean and tidy purpose.
3. Go to the Eclipse menu Windows → Preferences to set Global RISC-V Toolchains Paths to its
installed location as showed in the Figure 2 .
4. Create an environment variable RISCV32GCC_DIR and set it to GNU GCC Toolchain folder, for
example, D:\eclipse\GNU MCU Eclipse\riscv32-unknown-elf-gcc .
5. Add GNU GCC Toolchain executable files folder, D:\eclipse\GNU MCU Eclipse\riscv32-unknown-
elf-gcc/bin
, to the user or system PATH variable.
