1. JTAG Protocol JTAG (Joint Test Action Group) is an international standard testing protocol (IEEE 1149.1 compliant) primarily used for internal chip testing. Most advanced devices today support the JTAG protocol, such as ARM, DSP, and FPGA devices. The standard JTAG interface consists of 4 lines: TMS, TCK, TDI, and TDO, which are mode select, … Read more
What is a download debugger? In simple terms, a download debugger is a device that converts commands sent from a PC (for example, via USB protocol) into a language that the MCU (which manages the MCU’s internal peripherals) can understand (such as SWD or JTAG protocol), loads code, and precisely controls execution.What is a standard? … Read more

This series will introduce the basic knowledge of bare-metal programming with STM32 to better understand how frameworks and IDEs like STM32Cube and Keil work. This guide starts completely from scratch, requiring only a compiler and the chip’s datasheet, without relying on any other software tools or frameworks. This series covers the following topics: Memory and … Read more
When we write programs, we usually use JLINK to complete the operation. It must be said that JLINK is one of the most important tools in the embedded microcontroller industry. However, we sometimes encounter situations where programming fails. Not long ago, I faced a situation where programming could not be completed. The specific situation is … Read more
USB to Serial is a small tool often used for debugging microcontroller programs. The Jlink version V9 and above provides a virtual serial port function, which can be used for serial transmission and reception testing. The interface is defined as follows: pin 5 is Jlink-TX, and pin 17 is Jlink-RX. It is important to note … Read more
0. Introduction The documentation from ARM is already very good, but it still lacks clarity on what to do immediately after powering on, which caused me some trouble during my first use. Today, I will provide a detailed overview to help more friends. By the way, the ARM_Cortex-M0/3 DesignStart series will continue to be updated, … Read more
