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

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

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

Most advanced devices now support the JTAG protocol, such as DSP and FPGA Devices. The standard JTAG interfaces are four lines: TMS, tck, TDI, and TDO, which are the mode selectio
Homemade simple JTAG download and Writing Tool
For General Embedded Systems enthusiasts, it is unlikely that they will spend too much money to buy a relatively high-end debugging simulation tool to debug our own target board, the most economical method is to create a simple JTAG cable for flash writing. First, the bootloader is solidified into flash, because the bootloader compilation is very small, usua

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

according to Datasheet Documentation described, when when the Jtag_gpio_mode register is set to 1 , theJTAG pin function is gpio, and the corresponding Gpio sequence number is gpio17~gpio21.

Today, it has been a long time since the JTAG download problem of MSP430.
In the end, it is actually a problem with the port mode. In My bios, the default port is the SSP mode, but if JTAG is used, it needs to be changed to the ECP or EPP mode. after entering the BIOS to correct it, there is no problem, debugging is now available.
There is another problem that I don't know why. I have bought a 430 Develop

Because the Development Board on hand is relatively old, it is botron's netarm2410 and can only be started from nandflash. The hardware at hand is incomplete. There is only one simple Wigler JTAG. Here we recommend H-JTAG software, the latest version added support for nandflash, very easy to use.
