fruid-util

FRU Data Parser and Modifier

Overview

This Python script, fruid-util.py, is a tool for parsing, modifying, and rebuilding Field Replaceable Unit (FRU) data. It works with FRU binary files, allowing users to read existing FRU data, modify specific fields, and create new FRU files.

Features

• Parse existing FRU binary files
• JSON output of parsed FRU data
• Modify FRU fields including chassis, board, and product information
• Rebuild FRU binary data after modifications
• Create new FRU files

Requirements

• Python 3.6+
• No external dependencies required

Usage

usage: python3 fruid-util.py fru_file [-h] [-v] [-m] [field options]
