2. Roadmap Guide 🎯

This lecture is a roadmap 'Arm - advanced course for system software developers ' This lecture is included in .

If you want to learn Arm architecture (Armv8-A, Armv7-A) systematically , it is recommended to use the roadmap ( 30% discount on all lectures ). For reference, the Arm architecture roadmap (all author lectures) is Basic Course and Advanced Course It consists of two parts.

In the latest system software
The most important Arm architecture

The Arm processors used in smartphones, AI SoC system semiconductors, electric vehicles (autonomous driving, infotainment), cloud servers, and MacBooks are all Armv8-A based 64-bit Cortex-A processors (Cortex-A53, Cortex-A57, Cortex-A72, etc.). The Armv8-A architecture can be seen as the most needed basic knowledge in the current system software industry.

Attention System Software Developers, Embedded System (BSP) Programmers! 🙋‍♂

But what is the most frequently used feature in real-world projects among the key features of the Arm architecture, which is the rule for controlling the Arm processor with software? It is 'Trustzone'.

This is also a frequently asked question in career and entry-level interviews for system software developers.

Why specifically should we learn about Trustzone?

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

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

A lecture directly written by the author containing the know-how of a 12-year system engineer!

In my book, ' Arm Architecture Structure and Principles for System Software Development ' (Chapter 14), I cover 'Trustzone' in detail. I hope you will learn 'Trustzone' in depth through the author's lecture!

I recommend this to these people

After class

• You can understand the core concepts of the trust zone.

• Analysis of the relevant source code can reveal how the trust zone is implemented.

• Here are five features chipset vendors need to design their hardware to use TrustZone.

• You can confidently explain your trust zone in an interview.

Learn about these things

We will review the Arm spec document in detail to explain the components of TrustZone.

Describes the execution flow of the non-secure world and the secure world in the Armv7 architecture with assembly instructions.

We will review in detail the exception vector table of the Armv7 architecture and the handler code related to monitor mode.

This article details the execution flow of TrustZone in the Armv8 architecture along with assembly instructions.

We will explain the exception handler, exception vector table, and execution flow of TrustZone in the Armv8 architecture. You can also learn the operating principles of TrustZone by analyzing the Arm-Trusted Firmware code.

Based on my experience writing books and giving lectures
More in-depth and detailed than anyone else!

The author of the unprecedented 'Arm Architecture (Armv8-A, Armv7-A)' and 'Linux Kernel' books in the domestic system software field. He is also a working developer who knows the latest system software trends (electric vehicles, system semiconductors - system software) the best, and an educator who is most active in spreading knowledge in the system software field.

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

• Author of 'Learning the Structure and Principles of the Linux Kernel through Debugging' ( 2021, Korean Academy of Sciences Outstanding Book Award )

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

• June 2022, Korea Computer Conference (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 the educator who can explain the key features of the Arm architecture (Armv8-A, Armv7-A) better than anyone else in Korea.
