| 摘 要： | 提出一种基于串口通信来实现对汽车电控单元ECU代码的下载和调试方法，以解决长期以来依赖BDM对ECU进行代码下载和调试过程中出现的诸多不便．以美国飞思卡尔汽车级微控制芯片HCS9S12为研究对象，通过自主开发的调试软件实现了无BDM对ECU的代码下载与调试，实践证明该方法简单、可靠、成本低，有一定的应用推广价值．

| Abstract: | A new kind of code downloading and debugging method is proposed for engine control unit(ECU) based on serial port,thereout to solve inconveniences in complete code downloading and debugging to ECU by background debug module(BDM).With America Freescal automotive microcontroller as tudy object,function of downloading and debugging to ECU is realized by software developed without BDM,experiment result shows that the new code downloading and debugging method has advantages of simple,reliable and low-cost. |
