Have you encountered HardFault issues while using STM32? I was troubled by this issue for quite a while, so here’s a brief summary. Phenomenon reproduction: During debugging in simulation mode, when running at full speed and then stopping, the program hits the HardFault_Handler function, resulting in a HardFault, or hard error. The causes can be … Read more
