When the MCU code crashes, first determine whether the current stack being used is the MSP (Main Stack) or the PSP (Process Stack). After an exception occurs, the stack order of the ARM core is as follows: R0-> R1->R2->R3->R12->LR->PC->XPSR The LR (R14) register is the link register, which stores the exception return value EXC_RETURN where … Read more

Newcomers to embedded systems often encounter an unavoidable term: STM32. Whether browsing forums for “beginner-friendly guides” or asking industry veterans “where to start,” nine times out of ten, they will be recommended to tackle STM32 first. Some may wonder, there are many embedded chips, not just STM32. The 51 microcontroller is simple and easy to … Read more
Why We Are Discussing ItTo put it bluntly, the most frustrating aspects of embedded debugging are connection issues, visibility problems, inaccurate breakpoints, and chaotic logs. cortex-debug acts like a tool that collects these fragmented issues and assembles them into a smooth workflow. It’s not magic, but it truly transforms VSCode into a powerful debugging platform … Read more
