Design and implementation of Bootloader base on CAN bus

Bootloader function is one of the essential function of embedded system. In this paper, a bootloader is designed based on the 16-bit Freescale MCU MC9S12XEP100 and CAN bus, which includes driver module design, diagnostic module design, BOOT method design, memory module design, and Flash protected design. Through the experiment, the results show that bootloader designed could boot the application accurately, downloads and upgrades correctly.
