Introduction Remote debugging with QEMU is quite simple; just enable the -g parameter to bind to a local port. However, IDA requires some configuration to debug MIPS architecture binary files and pause processes for debugging. (There are many online tutorials on how to run IDA in Linux and set up the buildroot environment, or feel … Read more
1. Basic Mechanism of Driver Initialization Zephyr’s driver initialization is implemented through the following mechanisms: Device Tree : Hardware resources are defined through the device tree, and the driver relies on this information for initialization. Initialization Macros (DEVICE_DT_DEFINE and DEVICE_DEFINE) : The driver registers to Zephyr’s device model using these macros. Initialization Priority : The … Read more

As a Java programmer, have you encountered these issues: online faults that are hard to reproduce, debugging processes that are difficult to start, and testing scenarios that cannot cover edge conditions? Don’t worry, today I’m going to introduce you to a powerful tool: Byteman. It allows you to dynamically modify the behavior of Java applications … Read more
1 Reasons Driving Change in FPGA Debugging Technology The reprogramming capability of FPGAs is a key advantage in the functional debugging of hardware designs. In the early days of using CPLDs and FPGAs, when a design was found to be malfunctioning, engineers would use the “debug hook” method. They would route the internal signals of … Read more
PROFIBUS is an international, open, fieldbus standard that is independent of device manufacturers. The transmission speed can be selected from 9.6 kbaud to 12 Mbaud, and when the bus system starts, all devices connected to the bus should be set to the same speed. It is used for factory automation at the workshop level for … Read more
