摘　　要：BootLoader程序几乎是所有智能设备的必备功能。当产品出厂后如果发现有重大BUG或需功能升级,则它可以帮助工程人员方便的更新程序。嵌入式软件一般与硬件联系比较紧密,因此BootLoader程序的实现在不同的硬件平台上具有不同的方法,但是其实现的基本思想是一致的。提出了在BootLoader程序实现过程中普遍会遇到的几个难点问题,并以飞思卡尔公司ColdFire V1微控制器MCF51AC系列单片机平台为例介绍了这几个难点问题的解决方法,对其他平台具有借鉴意义。BootLoader program is the essential function of almost all intelligent devices. If the products are found to have significant BUG or need to be upgraded after leaving the factory, it can help engineers to easily update programs. Generally speaking, embedded software is more closely linked with the hardware. So that the successfully application of BootLoader program on different hardware platforms are diversified, in which, however, the same basic idea is applied. This paper raises several problems often encountered in the operation process of the BootLoader program and introduces the solutions for them by taking ColdFire V1 microcontroller MCF51AC MCU platform of Freescale Company as an example, which will present some references for the other platforms.
