Highlights: Detailed analysis of the impact of 5G edge computing on industrial structure. The demand for 5G computing power is driven by two main factors: signal processing and edge computing. On one hand, the increasing demand for communication signal processing imposes new requirements on computing power. On the other hand, 5G is the starting point … Read more
Currently, the EtherCAT slave solutions available on the market mainly include the following types. The traditional ones are chips like the Beckhoff ET1100, which require a master control + ESC + PHY, resulting in higher costs, making them unsuitable for the competitive pace of domestic general-purpose products. The second type integrates PHY with the ESC, … 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
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
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
Today, I bring you an ultra low-cost FPGA JTAG solution, where the hardware core is based on the Raspberry Pi Pico. Using related chips to create your own JTAG is very cheap; the RP2040 is priced at only 4 yuan on Taobao, making the production cost extremely low. Of course, the cost of using the … Read more
Welcome FPGA engineers to join the official WeChat technical group. Clickthe blue textto follow us 1. What is JTAG: Joint Test Action Group. JTAG is an IEEE standard designed to solve board-level issues, developed in the 1980s. Today, JTAG is used for programming, debugging, and probing ports. Of course, the original use was boundary testing. … Read more
In the process of FPGA development and learning, a key step is downloading to the board. Achieving hardware “hard presence” is very important, and generally, the JTAG port is more commonly used. Therefore, I believe that some experts must have encountered issues with the JTAG port becoming unresponsive or damaged and unable to be used. … Read more
JTAG is an IEEE standard (1149.1) developed in the 1980s to address manufacturing issues in electronic boards. Today, it can be used for programming, debugging, and probing ports. But first, let’s look at JTAG’s original purpose: boundary testing. Boundary Testing This is a simple electronic board (also known as a “Printed Circuit Board” or “PCB”) … Read more
