Hello, I am working on a project based on STM32F103VC microcontroller. I tried to find any resource/discussion/application note on clearing of internal SRAM after reset (i.e. initialization of SRAM). Although the topic seems trivial, it is strange that I was unable to find any resource nor example. I tried to investigate startup_stm32f10x_x.s files to find relevant routine without success. Could you please provide information/examples/advices how to clear internal SRAM after reset, what is the best way. If it has to be done in the startup file - plese, suggest an example. Could we use memset function called in the initialisation function before main and how to implement it in a problem-free manner (and any examples?)? Thanks in advance
