摘要
以电调天线远程控制单元为研究背景,介绍了一种遵循AISG2.0规范的固件更新策略的设计实现过程。针对传统远程固件更新策略存在的不足,提出利用MCU片内Flash进行固件存储的设计思路。依据AISG2.0中的相关规范,设计和实现了固件下载和固件激活功能。实际应用证明,该方案稳定、可靠、安全性好。
In terms of the design of RET control unit （ RCU）, a way of implementing firmware update function that conform to AISG2.0 is proposed. Aiming at solving the problems of the traditional firmware update meth- ods, a scheme of storing firmware by internal Flash memory of MCU is given. According to the related specifica- tions of AISG2.0, the design of firmware download and activation is provided in detail. Application shows that the proposed strategy is stable, reliable and well secure.
