CoreMark: Build with Extension (Example: LicheePi 4A)

This example uses CoreMark to demonstrate the basic workflow of completing toolchain installation, virtual environment creation, source extraction, build, and execution within the extension. For detailed instructions, see Building with Ruyi Compilation Environment.

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-plct-xthead.

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

    • Select sipeed-lpi4a as the Profile.
    • Choose the installed gnu-plct-xthead toolchain.
    • (Optional) Select a simulator.
    • Specify a name and path, then create and activate the environment by clicking its name.

  4. In the Explorer, right-click the target directory and select Extract RuyiSDK Package to unpack the coremark source code.

  5. Configure the build settings in the CoreMark source (refer to the CoreMark repository README):

    >_Terminal
    # Modify gcc according to CoreMark build instructions
$ sed -i 's/\bgcc\b/riscv64-plctxthead-linux-gnu-gcc/g' linux64/core_portme.mak

  6. Open the VS Code terminal (with PATH inherited from the activated environment), navigate to the coremark directory, and run the build:

    >_Terminal
    # Cross-compile and build to generate the executable coremark.exe
make PORT_DIR=linux64 link

  7. Transfer the generated executable to the LicheePi 4A and run it (using scp, serial, NFS, etc.).

Notes

  • To run in local simulation, select an appropriate QEMU simulator and execute in the terminal.
  • For device flashing and image deployment, refer to the package manager case documentation (the extension does not yet provide a flashing wizard).
