摘要: 针对嵌入式远程升级面临的boot功能以及存储器的限制,重点分析了ARM7工控设备在远程升级过程中面临的升级失败问题,提出一种基于分散加载技术的“双系统”存储体系结构,并详细阐述了“双系统”存储结构解决升级失败问题的原理。最后通过一组实验数据证明了其保证远程升级安全的效果。

关键词: ARM7, 远程升级, 升级安全, 存储结构, 双逻辑存储器, 分散加载

Abstract: According to the limitations of boot function and memory of embedded remote upgrade, the failure of remote upgrade procedure for ARM7 industrial control devices was analyzed. A storage structure named "Double-System" based on scatter loading was proposed, and its theory was described in detail. A set of experimental results verify its effect to ensure the safety of remote upgrade.

Key words: ARM7, remote upgrade, upgrading security, storage structure, double logical memory, scatter loading
