The Cortex-M architecture uses a vector table lookup mechanism. When an exception occurs, the core automatically looks up the entry address of the handler from the vector table. The vector table is essentially an array of WORDs (32-bit integers), where each index corresponds to a specific exception, and the value of that index is the … Read more

Recently, someone asked: What is the relationship between ARM9 and STM32? If we rewind 10 years, ARM9 and S3C2410 were quite popular, but the “new era” ARM processors like STM32 have also emerged. ARM9 is an early ARM processor, while STM32 is a more modern processor that has gained popularity in recent years. ARM Naming … Read more
Hello everyone, I am Pi Zi Heng, a serious technical guy. Today, I will talk about disassembly files in embedded development (.s, .lst, .dump). In the fourth, fifth, and sixth lessons, I introduced three types of output files generated by the compiler/linker (relocatable, map, executable files). These three files focus on how the compiled/linked code … Read more
Hello everyone, I am Pi Zi Heng, a serious techie. Today, I will talk to you about map files in embedded development. In the fourth lesson, I introduced the first type of output file – relocatable files. This article continues to discuss the second type of output file generated by the project – map files. … Read more
