This article is authored by Xilinx Engineer Hank Fu In the office, there is a VCK190 board running in SD boot mode, which can enter Linux. However, now that we are working from home, we cannot change the boot mode of the VCK190 board. We need to run a Standalone program. Therefore, we hope that … Read more
Author: Xilinx Engineer Hank Fu The office has a VCK190 board running in SD boot mode, which can boot into Linux. However, now that we are working from home, we cannot change the boot mode of the VCK190 board. We need to run a Standalone program. Therefore, we hope that like MPSoC, when the Versal … Read more
Exploring the JTAG interface of the 7-series Xilinx FPGA and Zener diode protection When I was selecting the 7-series Xilinx FPGA for a new PCB design, I was unsure about the design of the JTAG interface. To find a reliable reference, I reviewed several schematic diagrams of Xilinx evaluation boards, among which the schematic of … Read more

Introduction JTAG is something that IC and embedded enthusiasts must have used, but for those who don’t understand the internal workings of JTAG and its implementation, this article is worth a read. For those who have previously learned about coresight, you are aware of ARM’s internal debugging, knowing that the entry point for debugging lies … Read more
In 1985, European manufacturing organizations established the Joint European Test Action Group (JETAG) to research testing for integrated circuits. Later, in collaboration with North American companies, this organization was renamed JTAG (Joint Test Action Group) in 1986, and corresponding testing standards were designated. This standard was approved by IEEE in 1990 as an international standard … Read more
Many friends are transitioning from microcontrollers and are quite familiar with JTAG. They want to use JTAG to debug bare-metal code, but often encounter issues where the virtual machine cannot connect to the TF card. The I.MX6ULL itself supports JTAG, but there is really very little information available on this, and most of it is … Read more
