-begin- The define command can encapsulate quick commands for step-by-step debugging, but during regression testing or version iterations, multiple core dump files (more than 10) often arise. Analyzing them one by one not only takes time but may also overlook common issues.The gdb -x command can execute debugging operations in batches through scripts, traversing all … Read more
“The program suddenly freezes, and the log only reports ‘Segmentation fault’” “The kernel directly panics while running multiple threads” — Engineers working on Linux development have almost all encountered such “crash moments”. Facing on-site issues without debugging information is like a blind person trying to touch an elephant, and core dumps are the “key evidence” … Read more
Technical experience sharing, welcome to follow and provide guidance In the process of system development, the version deployed on the device is usually the release version, which generally does not contain debugging information. When issues arise, how do we troubleshoot? In fact, Linux provides the core dump feature, which generates a core file when a … Read more

Hello everyone, welcome to Lixin Embedded. In Linux development, core dumps are powerful tools for debugging program crashes. However, on devices with limited storage space, core dump files that can be several megabytes in size can take up a lot of space. In the previous article, we discussed the principles and generation mechanisms of core … Read more
1. In my previous article, I wrote an introduction to the ESP32, and I think it is necessary to write this article, which mainly focuses on analyzing core dumps. This is similar to crash analysis in Android and Linux systems; it is interesting yet challenging. When we write code, we inevitably encounter some core dump … Read more
Whether for databases or applications, when issues arise, knowing the exception stack information can greatly assist in identifying the root cause and fundamentally resolving the problem. The stack information from MySQL can similarly aid in problem-solving. This article from the technical community, 《MySQL Fault Reporting Core Dump Collection Process》 introduces the process of collecting core … Read more
