Coremark

基础示例 系统:FreeRTOS 更新:2026-05-07

RuyiSDK 基础示例

可直接在开发板上进行编译和运行的示例,适合初学者快速上手。

安装 ESP-IDF v5.5.4 及工具链

# 下载并运行 ESP-IDF 离线安装包(从乐鑫官网或 GitHub)
# 安装完成后,通过开始菜单中的 "ESP-IDF 5.5.4 PowerShell" 快捷方式打开终端

验证工具链

riscv32-esp-elf-gcc --version
idf.py --version

Coremark (GCC版)

创建并配置项目

idf.py create-project-from-example "espressif/coremark:coremark_example"
cd coremark_example

idf.py set-target esp32p4

验证GCC版本

riscv64-esp-elf-gcc -v

编译并运行coremark(GCC)

idf.py build
idf.py -p COM6 flash

idf.py -p COM6 monitor

正常情况下,终端会看到类似如下输出:

Coremark (LLVM版)

安装 Clang 工具链

python "$env:IDF_PATH/tools/idf_tools.py" install esp-clang

切换到 Clang 工具链

cd coremark_example
$env:IDF_TOOLCHAIN = "clang"

重新编译、烧录并运行

idf.py fullclean

idf.py build
idf.py -p COM6 flash monitor

正常情况下,终端会看到类似如下输出:
