发布时间：2018-10-05 15:34
【摘要】：嵌入式移动终端软件的升级在工程应用领域有着十分重要的作用,是软件开发和生产的重要环节。 本文主要对CDMA移动终端的软件烧录升级进行讨论研究,升级工具以高通平台(Qualcomm)协议为基础,对高通原有的下载升级工具QPST进行了固化BootLoader插件(Aprg)的改进。 首先,研究作为典型移动终端设备的CDMA手机的硬件结构,通过两种Flash芯片的对比对主要操作对象Nor Flash芯片进行介绍,分析移动终端与PC进行通信的接口USB串口技术。其次,分析嵌入式软件下载升级中起关键作用的BootLoader的作用、运行过程,引入作为高通BootLoader的Flash升级插件APRG。再次,设计软件总体结构和开发思路,将工具分三个层次进行开发：USB串口通信的底层,传递命令数据包的协议层,用户操作的控制层。通过协议层传递命令数据包,在用户控制层实现软件升级和插件固化操作。最后对工具进行了测试与验证,结果表明经过改进之后的下载工具可以大大提高移动终端下载软件的效率和可靠性。
[Abstract]:The upgrade of embedded mobile terminal software plays an important role in the engineering application field and is an important link in software development and production. This paper mainly discusses and studies the software burning and upgrading of CDMA mobile terminal. The upgrade tool is based on the (Qualcomm) protocol of Qualcomm platform. The original download and upgrade tool QPST is improved by solidifying BootLoader plug-in (Aprg). Firstly, the hardware structure of CDMA mobile phone, which is a typical mobile terminal device, is studied. Through the comparison of two Flash chips, the main operating object Nor Flash chip is introduced, and the interface USB serial port technology of communication between mobile terminal and PC is analyzed. Secondly, this paper analyzes the role and running process of BootLoader, which plays a key role in the download and upgrade of embedded software, and introduces APRG., the Flash upgrade plug-in, which is used as Qualcomm BootLoader. Thirdly, the overall structure and development idea of the software are designed. The tool is divided into three levels to develop the bottom layer of the USB serial communication, the protocol layer to transmit the command data packet, and the control layer of the user operation. Through the protocol layer to transmit command data packet, the user control layer to achieve software upgrade and plug-in solidification operation. Finally, the tool is tested and verified, and the results show that the improved download tool can greatly improve the efficiency and reliability of mobile terminal download software.
