在使用Zynq7045处理器的机载嵌入式模块上设计了一种在线升级方案,包含硬件设计和软件升级流程设计。该升级方案通过主备映像冗余保证模块中的BOOT及操作系统核心映像具有较高的可靠性,同时在升级流程中设计了映像完整性保护和一致性检查,确保在线升级过程中出现断电等异常后模块再次上电时能正常使用。
Abstract
In the paper,an online upgrade scheme is designed on the airborne embedded module using the processor of Zynq7045,including hardware design and software upgrade process design.The upgrade scheme can ensure that BOOT and operating system core images in the module have higher reliability through the redundancy of the primary and standby images.At the same time,image integrity protection and consistency check are designed in the upgrade process to ensure that the module is powered on again and can be used normally after abnormal conditions such as power failure occur in the online upgrade process.
