摘要
以Freescale 16位HCS12内核微控制器为例,设计了一种基于CAN Bootloader的整车控制器程序更新系统。通过底层Bootloader的程序引导与上位机的结合,实现了控制器的程序更新。实车验证表明,设计的Bootloader能正确的引导程序,程序更新过程快速稳定,可靠性高。
This paper taking the 16-bit Freescale microcontroller of HCS12 series as an example, introduces the design of vehicle control unit program update system based on the CAN bootloader. The controller program is updated through the bootloader boot program combined with the host computer. It is verified on the electric bus that the designed bootloader is able to guide the program correctly.The update progress is rapid and the system is reliable.
