This is the RISC-V architecture plugin that ships with Binary Ninja.

Building the architecture plugin requires the Rust language development tools.

Run cargo build --release to build the plugin. The plugin can be found in the target/release directory as libarch_riscv.so, libarch_riscv.dylib or arch_riscv.dll depending on your platform.

To install the plugin, first launch Binary Ninja and uncheck the "RISC-V architecture plugin" option in the "Core Plugins" section. This will cause Binary Ninja to stop loading the bundled plugin so that its replacement can be loaded. Once this is complete, you can copy the plugin into the user plugins directory (you can locate this by using the "Open Plugin Folder" option in the Binary Ninja UI).

Do not replace the architecture plugin in the Binary Ninja install directory. This will be overwritten every time there is a Binary Ninja update. Use the above process to ensure that updates do not automatically uninstall your custom build.
