Click the blue text above Tansy Laboratory To get more automotive cybersecurity news Perface Recently, I came across some testing materials from the production line and discovered some DFX related content. While organizing the panorama of the entire security field, debugging security was also mentioned. For various reasons, I decided to learn about DFX related … Read more
Perface When locating issues, strong skills are naturally required, but having a powerful tool will definitely help us a lot. The official IDE may not meet our needs, and we may need to look for other professional tools. Among them, the debugging tools provided by Lauterbach are highly regarded.This company specializes in providing high-end debugging … Read more
A few days ago, I saw the news that ARM launched the CoreSight SoC-600, achieving the next generation of debugging and tracing. What is the next generation? Now you can throw away the JTAG cables and debug and trace your SoC directly via WiFi, CAN Bus, Ethernet, or USB. Sounds promising, right? However, many people … Read more
Coresight has two main functions: debugging and tracing. 1. Debugging The debugger implements debugging functionality through DAP. 1.1. Single-Core Debugging System: One DAP, along with one AP and APBIC. External access to the DP is transformed by the DAP into AP access. The AP generates the AP bus through the APBIC, allowing access to debugging … Read more
Introduction: The previous article was only half written and not published yet, so here’s a quick note. Preface Recently, while working with Coresight, I had a persistent question: how does the funnel know which trace source corresponds to the input slave port? After discussing with the FAE from the chip manufacturer today, I finally understood … Read more
The channel interface is used for transmitting events between different Coresight components. It is implemented using two components: CTM: Cross Trigger Matrix, which receives CTI channel signals and broadcasts them to other CTIs. CTI: Cross Trigger Interface, which receives trigger signals, sends trigger signals, receives channel signals, and sends channel signals. Typical applications of the … Read more
