ChipInfo

Overview

Ameba series chips store their key information in eFuse, which is used for persistently storing immutable chip attributes.

This information includes the chip hardware version, sample status, global unique identifier (UUID), and memory configuration.

It provides essential support for system initialization, compatibility judgment, production management, and device tracking.
