Milk-V Duo: Build and Debug with Extension

This example follows the IDE documentation to demonstrate how to use the extension for toolchain installation and virtual environment creation, and how to run and debug within VS Code using SSH/gdbserver.

Steps

  1. Open VS Code and click the Ruyi icon in the sidebar to enter the extension homepage.

  2. In the Packages view, install gnu-milkv-milkv-duo-musl-bin.

  3. In the Virtual Environments view, click + to create a new virtual environment:

    • Select milkv-duo as the Profile.
    • Choose gnu-milkv-milkv-duo-musl-bin as the toolchain.
    • Specify a name and path, then create and activate the environment by clicking its name.

  4. Obtain the source code: in the Explorer, right-click the target directory and select Extract RuyiSDK Package to unpack the milkv-duo-examples source.

  5. In the VS Code terminal (with the virtual environment activated), run the build, or create VS Code tasks that invoke the toolchain from the virtual environment.

  6. Transfer and run:

    • Use scp to transfer the target program to the device (see the upload target in the Makefile from the IDE documentation).
    • Run the program in an SSH terminal, or configure VS Code’s C/C++ Remote Application to run remotely.

  7. Debug:

    • On the device, prepare gdbserver and run, for example: gdbserver :2345 ./your_binary.
    • On the host, use riscv64-unknown-linux-musl-gdb from the virtual environment to connect to the device:
>_Terminal
riscv64-unknown-linux-musl-gdb ./your_binary
target remote <device-ip>:2345
