"STM32 Bootloader串口下载命令使用文档-实现自定义下载软件逻辑"

The STM32 bootloader usage document provides a comprehensive guide on how to utilize the bootloader (or self-boot program) for the STM32 microcontroller. It includes detailed instructions on the serial port download commands, facilitating the handshake process between the serial port and the STM32's bootloader, as well as enabling functions such as reading, writing, and erasing the flash memory. With this document, users are able to implement their own logic for serial port download software. In addition, the document AN3155, authored in February 2023, offers a thorough explanation of the USART protocol employed in the STM32 bootloader. This protocol describes the specific commands supported by the microcontroller bootloader, providing in-depth insights into their functionalities. The application note is applicable to all STM32 products integrating any version of the bootloader, as delineated in AN2606 STM32 system memory boot mode, which can be accessed on www.st.com. The products covered in this document are listed in Table 1 and are collectively referred to as STM32 throughout the application note. Overall, these resources offer a wealth of information for individuals seeking to utilize the STM32 bootloader effectively. The thorough explanations and comprehensive instructions provided enable users to gain a comprehensive understanding of the serial port download commands and the USART protocol, empowering them to harness the full potential of the STM32 microcontroller.
