Detailed meaning of JTAG! JTAGIt is short for the header Letter "Joint Test Action Group (Joint Test behavior Organization)", which was founded in 1985, it is a PCB and IC testing standard developed by several major electronic manufacturers. JTAG was recommended to be approved by IEEE as IEEE1149.1-1990 Test Access Port and boundary scan structure standard in 1990. This Standard specifies the hardware and s

Design of general-purpose JTAG debugger Based on FPGA [Date:] Source: single-chip microcomputer and Embedded System Application Author: Ma junrehang, University of Electronic Science and Technology [Font:Large Medium Small] 　 The development of the system based on the concept of System Virtual Machine (ANN) is a new development direction for the simulator. The so-called systems on a chip are implemented by using the programmable t

For details, refer to the resource files I uploaded to csdn. I read them all and read the user guide, which is simple. Qpst is a transmission software developed for Qualcomm chips. Simply put, mobile phones that use Qualcomm's processing chips can theoretically use qpst to

ARM JTAG Debugging principleOpen-jtag Development Group1 PrefaceThis article mainly introduces the basic principles of ARM JTAG debugging.The basic content includes the introduction of TAP (TEST ACCESS PORT) and Boundary-scan ARCHITECTURE,On this basis, combined with ARM7TDMI, the JTAG debugging principle is introduced

It's not easy for a novice.and learning from the beginning is a very good thing.WatchTo debug arm, JTAG is one of the following arm 's debug interface protocols. When simulation, IAR, KEIL, ads, etc. have a common debugging interface, RDI is one of them, then how do we complete the Rdi-->arm Debug Protocol (JTAG) conversion? There are two ways to do this:1. Write a service program on the computer, parse the

FPGA devices are available in three configurations: Active configuration mode (as) and passive configuration mode (PS) and most commonly used (JTAG) configuration methods.as mode (Active Serial Configuration mode): Each time the FPGA device is power-up, the FPGA device The boot configuration operation process, which controls the external memory and initialization process, from the configuration device EPCS actively emit the number of reads The EPCS da

ArticleDirectory Fault 1 Summary Introduction Whether it is customer feedback or your own experience, USB-blaster cannot download and configure FPGA from time to time. The reasons are as follows: 1. The JTAG-related pins on FPGA Devices are faulty; 2. the USB-blaster is broken; 3. The 10-pin JTAG cable is not properly pressed. Among them, Article 1 has brought the most serious damag

Preludeto copy the definition of the JTAG, SW interface,Jtag:jtag (Joint test Action Group; joint testing team) is an international standard test protocol that is used primarily for in-chip internal testing. Most advanced devices now support JTAG protocols such as DSPs, FPGA devices, and so on. The standard JTAG interface is 4 lines: TMS, TCK, TDI, TDO, mode sele

Differences between SWD and JTAG and usageIt is the jlink pin diagram given in the segger manual. You can view the relationship between SWD pin and JTAG pin. I. Differences between SWD and traditional debugging methods 1. SWD mode is more reliable than JTAG in high-speed mode. In the case of a large amount of data, the JTAG
