中文 | English

Introduction

This example project is based on a bare-metal architecture and demonstrates the configuration and usage of the Secure M33 core. It can also serve as a template for further development or project creation, helping users quickly get started and extend functionalities.

Software Description

  • Developed on the Edgi-Talk platform.

  • Example features include:

    • Secure region configuration

    • Basic startup flow demonstration

  • The project code is structured clearly, making it easy to understand and port.

Usage

Build and Download

  1. Open and compile the project.

  2. Connect the board’s USB interface to your PC using the onboard debugger (DAP).

  3. Flash the compiled firmware to the board using your programming tool.

Running Result

  • After flashing and powering on, the board will start the system normally.

  • It will successfully boot into the M33 core, indicating that the secure configuration is effective.

Notes

  • To modify the graphical configuration, use the following tools:

tools/device-configurator/device-configurator.exe
libs/TARGET_APP_KIT_PSE84_EVAL_EPC2/config/design.modus

  • Save changes and regenerate code after editing.
