A.1.1. Toolchain for Application and BSP
The risc32-unknown-elf toolchain is included in RiscFree* IDE by default. Toolchain configuration is not required to build the software for current Nios® V processor system.
To build an application or BSP with a toolchain other than risc32-unknown-elf, perform these configuration steps to include the other toolchain to the build path:
Note: If you configure the BSP setting file to use the RiscFree* IDE toolchain (risc32-unknown-elf), do not perform this configuration.
Follow the steps below to include the toolchain in path of the RiscFree IDE builder:
- Download the open source GNU RISC-V Embedded GCC package version v10.2.0-1.2 or later that supports the necessary RISC-V Instruction-Set Architecture (ISA).
- Extract the package in <Intel Quartus Prime installation directory>/niosv/ directory. Use the same directory for Linux* and Windows*.
- Right click the project under the Project Explorer section and click Properties.
- Go to C/C++ Build > Environment. Double click PATH variable to add the toolchain path. Example on adding xpack-riscv-none-embed-gcc toolchain:
- Linux* (add “:” as a separator for multiple path variables):
<Intel Quartus Prime installation directory>/niosv/xpack-riscv-none-embed-gcc-10.2.0-1.2/bin
- Windows* (add “;” as a separator for multiple path variables):
<Intel Quartus Prime installation directory>/niosv/xpack-riscv-none-embed-gcc-10.2.0-1.2/bin
- Linux* (add “:” as a separator for multiple path variables):
- Click OK and Apply & Close.
