0h00000000, 1 month ago @azonenberg ST products have a built in bootloader over UART/I2c, if you have right pins connected to your host controller you can use it to flash slave MCU. Or you could make a tiny bootloader and store in first page of flash and never overwrite it. https://www.st.com/resource/en/application_note/an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics.pdf
