☞ This is the 13738th article published by Metal Processing (mw1950pub) Editor’s Note 1 Introduction Profibus-DP network is a widely used fieldbus technology for data communication and control in the automation system monitoring layer and lower layer. It represents the development of automation technology but often experiences communication interruptions during actual operation. If the situation … Read more
With the official release of the first RISC-V Chinese book “Hands-On CPU Design – RISC-V Processor Edition” more and more enthusiasts are starting to use the open-source Hummingbird E203 RISC-V core, and many beginners have left messages asking about the use of the RISC-V toolchain. To facilitate beginners in quickly learning RISC-V CPU design and … Read more
The previous two articles introduced the basic principles of boundary scan and BSDL files. This article introduces two software tools commonly used for boundary scan testing. In the practical application section, we will demonstrate boundary scan testing applications based on STM32 and FPGA. This article introduces two commonly used boundary scan testing software: XJTAG and … Read more
Many development boards use NOR Flash such as AM29LV800 or AM29LV160, and can operate normally with the u-boot provided by this website; yesterday, a user discovered that they could not erase SST39VF1601, for example, the following phenomenon occurred: when attempting to erase a sector starting at 0x2000, it showed success, but reading the contents revealed … Read more
Previous article, introduced the JTAG boundary scan application based on STM32F103, demonstrated the application of TopJTAG Probe software, and the basic functions of boundary scan. This article introduces the boundary scan application based on Xilinx FPGA, which is almost the same. 1. Obtain the Chip’s BSDL File The method of obtaining the BSDL file for … Read more
The JTAG interface is a type of interface used for downloading programs, and it is also frequently connected and disconnected while powered. It is well-known that hot-plugging can inevitably generate some surges or ESD (Electrostatic Discharge). Therefore, if protective measures are not taken, it is easy for surge ESD to break down the JTAG-related pins, … Read more
Hardware Introduction Currently, there are mainly two types of AMD-Xilinx FPGA-JTAG in China: one is the official development board: The second is the newly launched smart lynq (faster and more functional): The price discourages a large number of people: The second type is domestic, with various kinds that I won’t show images of. Domestic JTAG … Read more
1. Basic Knowledge of JTAG JTAG stands for Joint Test Action Group and is the IEEE 1149.1 standard. The advantage of using JTAG is that it allows integrated circuits to be tested on a PCB through boundary scan. In the ARM7TDMI processor, JTAG can directly control ARM’s internal bus, I/O ports, and other information for … Read more
