Mastering JTAG Tools: Using JTAG Probe to "Reverse Engineer" Hardware Circuits

On various second-hand websites, you can often find boards that lack accompanying documentation (such as schematics), and these boards are relatively inexpensive. If purchased in bulk, they can be used as development boards. The first challenge is to “reverse engineer” the schematics for subsequent routine development. Currently, there are two software tools that can assist … Read more

JTAG Download Method Summary for Altera FPGA with Nios II Core

1. For Altera FPGA, when using Nios II, there are four types of files that need to be downloaded: .sof file, .pof file, .jic file, and .elf file. 2. The .sof file and .pof file are usually referred to as FPGA “hardware” or “firmware” files, generated by design compilation in Quartus II. The source file … Read more

Simplified Method for JTAG Interface in STM32 JLINK Programming

by

Simplified method for using JLINK to download programs to STM32 via JTAG interface (SW and JTAG modes)! Anyone who has used STM32 knows that there are two common methods for downloading programs: via serial port and JLINK. The serial port download method is quite similar to that of the 51, so I won’t elaborate on … Read more
