This document uses the k230d_canmv_defconfig configuration as an example. If you use other configurations, replace k230d_canmv_defconfig with correct names. All the configurations supported by this sdk, can be found in buildroot-overlay/configs directory.
sudo make toolchain_and_depend
#The above command will install GCC and the SDK's dependent packages. For details, refer to the tools/install_toolchain_and_depend.sh file
This SDK has been verified on Ubuntu 22.04 and 24.04, and other versions may have compilation issues.
Only the k230d_canmv_ilp32_defconfig requires additional manual installation(see command below) of the rv64ilp32 toolchain:
#only k230d_canmv_ilp32_defconfig need wget -c https://github.com/ruyisdk/riscv-gnu-toolchain-rv64ilp32/releases/download/2024.06.25/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25-nightly.tar.gz; mkdir -p /opt/toolchain/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25/; tar -xvf riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25-nightly.tar.gz -C /opt/toolchain/riscv64ilp32-elf-ubuntu-22.04-gcc-nightly-2024.06.25/; #only k230d_canmv_ilp32_defconfig need
