What you will gain after the course

  • Able to grasp the basic operating principles of Arm architecture (Armv8-A, Armv7-A)'s Trustzone (Trustzone).

  • Understand how Arm architecture's TrustZone is used in real projects.

  • You can broadly grasp the Trustzone-related execution flow and structure in the big picture.

  • I can well answer questions related to Trustzone (Trustzone) in an interview.

2. Roadmap Guide 🎯

This lectureRoad Map'Arm for System Software Developers - Advanced Course'is included in the course.


For those who want to learn Arm architecture (Armv8-A, Armv7-A) systematically, it would be good to utilize the roadmap (30% discount on all courses). For reference, the Arm architecture roadmap (all courses by the author) isBasic Course andAdvanced CourseIt consists of 2 components.

In the latest system software
The most important Arm architecture

Not only smartphones, but also AI SoC system semiconductors, electric vehicle Automotive (autonomous driving, infotainment), and Arm processors used in cloud servers and MacBooks are all Armv8-A based 64-bit Cortex-A processors (Cortex-A53, Cortex-A57, Cortex-A72, etc...). Currently, the Armv8-A architecture can be considered the content that requires the most foundational knowledge needed in the system software industry.

System software developers and embedded systems (BSP) programmers, pay attention! 🙋‍♂

However, among the main features that make up the Arm architecture, which is the rule for controlling Arm processors through software, what is the feature most frequently utilized in real-world projects? It's 'Trustzone'.

This is also a question that frequently comes up in interviews for both experienced and entry-level candidates when hiring system software developers.

Specifically, why should we learn about TrustZone?

In fact, 'Trustzone' was originally used as a security extension feature, but now most Arm processors use 'Trustzone' enabled by default. Arm processors used in smartphones as well as infotainment and autonomous driving in electric vehicles have Trustzone enabled.

To understand the overall structure of the system, 'Trustzone' is a feature that must be understood.


12 years of system engineer expertise packed into this author-led course!

I cover 'TrustZone' in detail in Chapter 14 of my book 'Architecture and Principles of Arm for System Software Development'. I hope you'll learn about 'TrustZone' in depth through my author-led lectures!

I recommend this for people like this

✅ System software developers who want to understand the operating principles of TrustZone in Arm architecture

✅ Developers who want to know how TrustZone's key features are utilized in real projects

✅ Security developer who develops security solutions utilizing Arm's TrustZone

After taking the course

  • You can understand the core concepts of TrustZone.

  • You can understand how TrustZone is implemented through analysis of related source code.

  • You can learn about the 5 features that chipset companies need when designing hardware using TrustZone.

  • You can confidently explain TrustZone in interviews.

You'll learn content like this

Reviews the Arm specification documents in detail while explaining the components of TrustZone.

Explains the execution flow between the non-secure world and secure world in Armv7 architecture along with assembly instructions.

Other Arm architecture-related documents or seminars only explain the basic concepts of TrustZone.
This course is different. It covers content that can be directly applied to real-world development!


We will conduct a detailed review of the exception vector table and monitor mode-related handler code for the Armv7 architecture.

This provides a detailed explanation of the TrustZone execution flow in the Armv8 architecture along with assembly instructions.

This explains the execution flow of exception handlers, exception vector tables, and TrustZone in the Armv8 architecture. You can also learn the operating principles of TrustZone by analyzing Arm-Trusted Firmware code.

Based on book writing/lecture experience
Deeper and more detailed than anyone else!

I am the unprecedented author in the domestic system software field who wrote books on 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel'. I am also a current industry developer who best understands the latest system software trends (electric vehicles, system semiconductors - system software), and an educator who is most actively engaged in knowledge dissemination activities in the system software field.

  • Author of 'Structure and Principles of Arm Architecture for System Software Development' (2024 Korea Academy Outstanding Book Award)

  • 'Learning Linux Kernel Structure and Principles Through Debugging' (2021 Korea Academy Outstanding Book Award) Author

  • 'Programmers Dev Course: Linux System and Kernel Expert' Main Instructor

  • June 2022, Korea Computer Congress (KCC2022) - Tutorial Presentation [Conquering the Linux Kernel Using ftrace]

  • LG Electronics 'Linux Kernel' and 'Armv8 Architecture' In-house Instructor (including domestic and overseas developers) - (2020~2024)


I can confidently say that I am an educator who can explain the key features that make up the Arm architecture (Armv8-A, Armv7-A) better than anyone else in Korea.
