Setting up RISC-V Toolchain - Mac

1. Install RISC-V Toolchain

First, we need to install the following dependencies.

brew install python3 gawk gnu-sed gmp mpfr libmpc isl zlib expat texinfo flock

Clone the RISC-V GNU Toolchain repo.

cd ~/Downloads
git clone https://github.com/riscv-collab/riscv-gnu-toolchain.git
cd ~/Downloads/riscv-gnu-toolchain/

Run configuration. The prefix is where we want to install the toolchain. Here, we will be installing under the riscv64-unknown-toolchain directory.

./configure --prefix=/home/tk/Documents/RISCV/riscv64-unknown-toolchain/ --with-multilib-generator="rv32i-ilp32--;rv32im-ilp32--;rv32iac-ilp32--;rv32imac-ilp32--;rv32imafc-ilp32f--;rv64imac-lp64--;rv64imafdc-lp64d--"

Build the toolchain

make -j8

2. Install OpenOCD

brew install [--HEAD] openocd
