摘要
在嵌入式系统的使用过程中,或者在软件开发过程中,系统软件可能经常被损坏。开发人员需要方便地把嵌入式操作系统、文件系统和用户应用程序下载到特定的硬件平台。目前,通常的做法是使用专用的仿真器,或者在Bootloader中增加下载的功能。针对这两种方法的不便,提出了一种通用的更新机制——基于Bootloader的双系统更新机制,并在飞利浦STB810平台上实现。
In the process of using embedded system or developing software, it is possible that system software is damaged. It should be convenient for developer to download embedded operating system, file system and application software into specific hardware. Now, this function can be implemented by adding download software in Bootloader or using simulator. Due to inconvenience of above two methods, a new general update mechanism of double OS is presented in this paper. At last, software design based on Philips STBSIO is given.
