As a car owner, you may be unfamiliar with BSD bus communication failures, but you have likely encountered issues caused by it, such as the water pump running continuously, inability to measure oil, inability to reset after oil maintenance, emergency power generation by the … Read more
Hello everyone, I am Pi Zi Heng, a serious tech enthusiast. Today, I will talk about the interface standard JTAG in embedded debugging. In embedded development, it is inevitable to simulate and debug code, especially when the application logic becomes complex to a certain extent. It is common to introduce some logical bugs while writing … Read more
1. Introduction Previously, we sharedhttps://mp.weixin.qq.com/s/BeL6UbSg2HI9qKemZugOhw?token=1054074707&lang=zh_CN the article titled“Low-Cost Learning FPGA Based on“Mining Board”” which usesJTAG boundary scan for quick pin correspondence reverse engineering.. Not only forFPGAs, but we can also useJTAG for boundary scan testing inMCUs, provided that the corresponding chip supports this feature and the manufacturer providesBSDL files. Here, we will demonstrate using theLPC1857 … Read more
1. What is a BSDL File? In the last article, we introduced the basics of JTAG boundary scan, today we will look at a file that is essential for boundary scan testing, the BSDL file. BSDL, Boundary Scan Description Language is an abbreviation for Boundary Scan Description Language, a subset of VHDL that conforms to … 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
