Keil Build

Keil Project Compilation

Invoke py_keil_build.py to compile projects via Keil UV4 command-line interface, and return structured build results.

Tool Script

Script Path: py_keil_build.py Dependencies: Python 3.x standard library + Installed Keil MDK (with UV4.exe)

Usage

# Incremental build (default)
python py_keil_build.py -p <project.uvprojx>

# Full rebuild (clean rebuild)
python py_keil_build.py -p <project.uvprojx> -r

# Specify UV4.exe path
python py_keil_build.py -p <project.uvprojx> -k "D:\keil\UV4\UV4.exe"

Parameter Description

Output Structure

Returns JSON format result:

{
  "status": "success",       // "success" or "failed" or "error"
  "log_path": "C:\\project\\Objects\\GD32F303RCT6.build_log.htm",  // 编译日志路径
  "errors": 0,                // 编译错误数
  "warnings": 3               // 编译警告数
}

Notes

• Keil default installation path: D:\application\keil_v5\UV4\UV4.exe, if different please specify with -k
• Build output is printed directly to terminal (no log file generated)
• Build success is determined by checking if *build_log*.htm exists after compilation
  • First checks: <project_dir>\Objects\*build_log*.htm
  • Falls back to searching recursively in project directory

Typical Workflow

1. First use keil-parser to confirm project configuration is correct
2. Call this tool to build, check if errors_count is 0
3. After successful build, use jlink-download to flash firmware
