Introduction   JTAG系列主要使用ChatGPT(free version)生成的,毕竟现在AI火爆的一塌糊涂,然而AI并不是包办一切,提示词很重要,并且后期的核对更重要,因为AI越来越会编造“事实”了.但这并不妨碍使用AI来提高工作效率,是指数级提高.   回归主题,前面学习了JTAG,正好手边有Jlink和板子,可以实践下了. OPENOCD   因为要支持比...

Preface Modern ARM-based SoCs expose powerful debug and trace capabilities through a layered architecture defined by IEEE 1149.1 (JTAG) and ARM CoreSight. This article explains, step by step, how ...

Introduction In modern ARM-based SoCs, JTAG debug access is a key mechanism for software development, system validation, and manufacturing test. However, enabling JTAG is not as simple as toggling...

Introduction The Joint Test Action Group (JTAG) interface, standardized as IEEE 1149.1, is a fundamental technology for board-level testing, debugging, and in-system programming of integrated circ...

Preface This part focuses on comparing JTAG and SWD, describing standard connectors, and highlighting board-level design considerations for reliable debugging. 1. JTAG vs SWD 1.1 JTAG (IEEE 11...

Preface This article focuses on the software layer of JTAG debugging: the tools that control debug probes, understand CPU debug architecture, and expose interfaces to developers through GDB or int...

Preface This article focuses exclusively on the JTAG adapter (also called a debug probe)—what it is, how it works, and what engineers must understand when selecting and using one. Later parts will...

Preface The Elliptic Curve Cryptography (ECC) is modern family of public-key cryptosystems, which is based on the algebraic structures of the elliptic curves over finite fields and on the diffic...

Background   首先来解决ROM Lib是啥？为什么要使用它？来看AI的解答： A “ROM library” refers to a collection of functions or code stored directly in a device’s Read-Only Memory (ROM), allowing applications to access th...
