【摘要】 基于UDS协议设计了一种Bootloader,基于CAN节点MCU生成Flash驱动程序的指令数据,在软件升级过程中实时下载到MCU的RAM空间,保证Flash地址空间不存储Flash驱动程序,从而避免了程序数据被Flash驱动程序误擦除的隐患,并研究了多帧通信过程及其STmin和BS设置对软件升级时间的影响。更多还原

【Abstract】 Based on the UDS protocol,a Bootloader is designed.The instruction data of the Flash driver is generated based on the CAN node MCU.It is downloaded to the RAM space of the MCU in real time during the software upgrade process to ensure that the Flash driver is not stored in the Flash address space,thus avoiding the program data being erased by the Flash driver,and the effect of STmin and BS settings on multi-frame communication on software upgrade time are studied.更多还原
