| Abstract: | For the difficulties of auto-body ECU＇s software upgrade,a method of ECU＇s upgrade based on CCP and CAN bus is presented after illustrating the principle of In Application Programming（IAP） technology.Besides,the implementation on the XC167CI is given in the paper.The processing method of load file in the load tool and the implementation method of bootloader are expounded.Experimental result shows that the system not only achieves the function of application code upgrade but also runs stably. |
