Original: Wolonghui Wolong Village Master Previously, some netizens asked what the JTAG principle is? Today, I will briefly explain it. JTAG is a debugging, testing, and online programming interface. JTAG (Joint Test Action Group) JTAG is an embedded debugging technology used to test chips. Once the circuit board is soldered, how can we ensure that … Read more
Source: FPGA Resource Hero In the process of FPGA development and learning, a critical step is the board download implementation. Achieving hardware “hard realization” is crucial, and generally, the JTAG interface is more commonly used. Therefore, many experts must have encountered issues with the JTAG interface malfunctioning or being damaged and unusable. Recently, I faced … Read more
To debug ARM, you must follow the ARM debugging interface protocol, and JTAG is one of them. During simulation, IAR, KEIL, ADS, etc., all have a common debugging interface, and RDI is one of them. So how do we convert RDI to the ARM debugging protocol (JTAG)? There are two approaches: Write a service program … Read more
