| 摘 要： | 在阐述了在应用编程(IAP)基本原理的基础上,给出了一种基于Zigbee的IAP在线升级方案。对在应用编程(IAP)在线升级的原理进行了分析,以ARM芯片LPC2292为例解释了地址重映射、堆栈设置、分散加载文件的设置和状态转换等难点,然后结合Zigbee无线通信网络技术,详细阐述了通过IAP进行在线升级的方案,并对Zigbee协议进行了改进.此方案快捷简便,减少了实现的硬件成本,降低了更新中的通信误码率。最后设计了更新异常情况下的紧急更新方案,解决了更新中系统掉电等关键技术问题。

| Abstract: | One solution based on Zigbee and IAP for online updating is given.Firstly,the theory of IAP online updating is analyzed,such as the remapping of the address,the installing of the stack,the changing of the mode,the setting up of scatter document and so on.Secondly,the solution involving Zigbee networks has been improved,which reduces the communication errs in technology.Finally,the resolution of urgent updating is generated after analyzing the reliability of the updating,which resolves the key problem of power-failing during the updating of the system. |
