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.
