Click the blue text above Tansy Laboratory To get more automotive cybersecurity news Perface Recently, I came across some testing materials from the production line and discovered some DFX related content. While organizing the panorama of the entire security field, debugging security was also mentioned. For various reasons, I decided to learn about DFX related … Read more
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
What is CmBacktrace Let’s break down the name: Cortex Microcontroller Backtrace, sounds impressive. In simple terms, it is an open-source error tracking library specifically designed for ARM Cortex-M microcontrollers, capable of automatically capturing fault causes in various “crash” scenarios such as assertions (assert), hard faults (HardFault), memory management faults, bus faults, and usage faults. It … Read more
Recently, after upgrading the ESP32 firmware to LVGL 9.2.2 + MicroPython 1.25, previously functioning code began to experience crashes and restarts. At this point, the following error message can be seen: A fatal error occurred. The crash dump printed below may be used to help determine what caused it. If you are not already running … Read more
CmBacktrace Fault Diagnosis In the world of embedded development, ARM Cortex-M series microcontrollers are widely used in various embedded systems due to their high performance and low power consumption. However, as system complexity increases, developers often feel helpless when facing issues like “Hard Faults.” Quickly locating and resolving these errors has become a significant challenge … Read more

Access, Inspect, and Control The term “debug” has a legendary history. According to various sources, the word debug was coined in 1945 by computer pioneer and U.S. Navy Rear Admiral Grace Hopper when she removed a moth from the Harvard Mark II computer. The use of the word bug can also be traced back to … Read more
Have you encountered the HardFault issue while using STM32? I was troubled by this issue for a long time, and here’s a brief summary of it. Phenomenon restoration: During simulation debugging in debug mode, when running at full speed and then stopping, the program jumps to the HardFault_Handler function, resulting in a HardFault, which is … Read more
