摘要
为了升级便携式设备的固件,开发一种基于USB接口的固件升级程序,使得操作方便,快捷。介绍固件文件的生成,搜寻升级设备的系统路径,下载设备的二级Boot代码的实现方法。测试表明,固件升级程序稳定,兼容性良好,界面简洁友好,只需几个简单操作就能实现系统固件升级。该固件升级程序设计可应用于多数便携式设备中。
A firmware upgrade program based on USB interface is developed for upgrading the portable device firmware .The implementation of the generation of firmware file, searching of system path of device and boot code of the download device are introduced.The test indicates that the upgrade program is steady, compatible and friendly, it makes the firmware upgrade only with a few simple operations,also is used in the majority of portable devices.
