Debugging chips relies heavily on the JTAG interface. Downloading and debugging programs must be accomplished through the JTAG interface. Today, I learned some basic principles and working processes of the JTAG interface, and I will summarize them briefly. The JTAG interface is an international standard testing protocol, originally initiated by several electronic device manufacturers who … 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
