Working With STM32 Arm TrustZone-Based Projects in CLion | The CLion Blog

The blog post by Jan Papesch offers an in-depth look at working with STM32 Arm TrustZone-based projects using CLion, focusing on setting up and managing such projects effectively. The TrustZone technology splits firmware into secure and non-secure zones to protect critical tasks from potential vulnerabilities in exposed interfaces like Wi-Fi or Bluetooth. The post guides users on configuring their environment, using tools like STM32CubeProgrammer and STM32CubeCLT, and setting up a project structure in CLion that includes two independent subprojects within a superproject. It also addresses debugging challenges and provides tips for managing CMake run configurations and debugging setups, including using a Generic debug server for complex cases. Additionally, it covers disabling TrustZone mode if needed and encourages user feedback to enhance STM32 project support.
