As the title suggests, let’s get started. First, prepare the program as follows: #include <iostream> #include <csignal> #include <atomic> std::atomic<int> running(1); void signalHandler(int signal) { std::cout << "Received signal " << signal << std::endl; running = 0; } int main() { signal(SIGTERM, signalHandler); while(running.load()) { } std::cout << "End" << std::endl; return 0; } After … Read more
In the production and collection activities of natural resource geographic information data, ArcGIS and ArcGIS Pro are possibly the most widely used GIS software. Correspondingly, Geodatabase databases (File GDB, Personal GDB) are also the most widely used formats for data production and aggregation. In the geographic information data collection and mapping production activities based on … Read more
When it comes to learning embedded systems, there is undoubtedly a lot to learn and remember. Writing this down helps me reconstruct problems and receive guidance from peers. 1. What is GDB? During our programming journey, we inevitably encounter program crashes, variable anomalies, and logical errors. This can be particularly frustrating for technical support workers … Read more

1. Background and Significance In our daily work, we sometimes need to batch convert database tables into points. ArcGIS does not provide a direct tool for this, so we need to link several tools together in the model builder to create a new tool. Please continue reading. 2. General Approach Use the “Iterate Tables” iterator … Read more
To quickly locate program issues, it is necessary to compile gdb 16.2 on the RK3399 development board and use gdb 16.2 to debug the program.

In 2021, I introduced the basic principles and configuration of the Zephyr tracing system in two articles: Introduction to Zephyr Tracing System – Part 1 and Configuration and Invocation Framework of Zephyr Tracing System – Part 2. At that time, Percepio only offered paid software, so I did not continue writing about how to use … Read more
Introduction to GDB The GNU Project Debugger (GDB) is a long-standing program written by Richard Stallman in 1986, supporting multiple languages including C/C++ and modern languages like Rust. GDB is a command-line application, but there are many graphical user interface front-ends and IDE integrations available. For this tutorial, we will use the command-line interface as … Read more
OpenOCD is used to drive the JTAG interface, typically in conjunction with GDB for code execution debugging. The usage of GDB is fundamentally no different from its use in other contexts.Some debugging techniques for GDB: Advanced Usage of GDBThere are two ways to start GDB and interact with OpenOCD: GDB communicates with OpenOCD over TCP … Read more
C++ Debugging Techniques: Using GDB for Breakpoint Debugging In C++ development, debugging is an indispensable part of the process. Whether you are a novice or an experienced programmer, mastering effective debugging techniques can significantly enhance development efficiency. This article will introduce how to use GDB (GNU Debugger) for breakpoint debugging, providing detailed code examples and … Read more
