Free Udemy Course 2025: ARMv8-M Trust-Zone on Cortex-M33: Embedded Security

Learn how to secure modern embedded systems using ARMv8-M TrustZone on Cortex-M33 microcontrollers. This comprehensive course is designed for embedded developers, firmware engineers, and IoT professionals who want to implement trusted execution environments and achieve fine-grained security in ARM-based systems.Using the powerful LPC55S69 MCU and tools like Keil MDK and CMSIS, you'll gain both theoretical understanding and practical skills to build, test, and debug TrustZone-enabled applications in C.You’ll also learn how to analyze and debug security-critical code at both the C and assembly level, ensuring you understand exactly how transitions and isolations are handled at the hardware level.What You Will Learn:Overview of the ARMv8-M architecture and its key security enhancementsHow TrustZone technology works on Cortex-M33 for embedded systemsDifferences between Secure, Non-Secure, and Non-Secure Callable (NSC) statesStep-by-step setup of SAU (Security Attribution Unit) and IDAUHow to partition memory based on security attributesDeep dive into new ARMv8-M instructions (SG, BLXNS, BXNS) for secure state switchingHandling Secure and Non-Secure interrupts and transitions safelyPractical C examples using CMSIS security macros and attributesBuilding projects with Makefiles, running on Keil MDK and LPC55S69 MCUDebugging embedded security labs at both C and assembly levelTools & Technologies:ARM Cortex-M33 (LPC55S69)ARMv8-M TrustZoneCMSIS (Cortex Microcontroller Software Interface Standard)Keil MDK (Arm Development Studio)Makefile-based C projectsWho Should Take This Course:Embedded systems developers looking to implement secure firmwareIoT engineers aiming to enforce hardware-level isolationFirmware developers working with ARM Cortex-M33 or TrustZoneAnyone interested in learning about ARMv8-M security featuresThis is an advanced course, therefore you will need to have some experience on embeddd systems and ARM architectureBy the end of this course, you’ll be able to confidently design, build, debug, and maintain secure embedded applications using ARM TrustZone, ensuring system integrity and protection in real-world environments.
