6.2 Overview

The Boot ROM is the entry point of the device following any type of reset. It performs a series of vital checks, including image validation and configuration verification. If these checks pass, the CPU loads the initial Program Counter (PC) and Stack Pointer (SP) values from Flash memory and begins executing the user code.

The Boot ROM also provides the Interactive mode, allowing both hot-plugging and cold-plugging of a debugger and programming.

Note:

Throughout this document, Debugger shall be interpreted as SWD-Host (and vice-versa) that is supporting this device.
