2.5.2 Manufacturing Utility

Introduction
This utility is designed to create instances of factory NVS partition images on a per-device basis for mass manufac-
turing purposes. The NVS partition images are created from CSV files containing user-provided configurations and
values.
Please note that this utility only creates manufacturing binary images which then need to be flashed onto your devices
using:
• esptool.py
• Flash Download tool
the doc folder.
• Direct flash programming using custom production tools.
