| Abstract: | This paper describes the design of USB bootloader based on Silicon Labs＇ CS051F34x serial MCU, that possesses the ability to receive new application firmware through USB or COM. Firstly, it introduces the USB Bootloader of MCU. Then, it expands the design of USB bootloader firmware and the design of application firmware, as well as the problems of design process that need attentions. Lastly, the bootloader software is designd using Visual C＋＋ 6.0, achieving remote update the APP FW. This USB bootloader is very universal and can be easily ported to other architecture like MCUs. |
