| Abstract: | Aiming at the problem that user code needs to be updated and repaired continuously during the development of engine MPC5634M controller,a BootLoader based on Unified Diagnostic Service(UDS)is designed to upgrade the application program of controller.This paper first introduces the working principle of BootLoader,then designs the BootLoader and the upper computer software,and finally tests the performance of the controller.The experimental results show that the BootLoader can upgrade the program online stably and reliably to meet the design requirements. |
