摘　　要：通过接入仿真器升级程序复杂繁琐,且在外场升级维护时更加不便,针对这种问题,提出了一种基于以太网实现的国产系统级芯片(SOC)软件在线升级方式。研究并实现国产SOC芯片的在线升级过程。该方式采用双网段来提高系统的容错性,并且基于国产SOC芯片的自身特点,完善在线升级后的掉电顺序来进一步确保升级过程的稳定。此方法已在某航天综合控制器上得到应用,并且可以支持多块板卡的同时升级,证明了此升级方法的便捷性与可靠性,具有一定的工程应用价值。A domestically produced System on Chip(SOC)software online upgrade method based on Ethernet is proposed to address the complex and cumbersome process of upgrading programs through the integration of simulators,which is more inconvenient to maintain in the field.Research and implement the online upgrade process of domestic SOC chips.This method adopts dual network segments to improve the system's fault tolerance,and based on the characteristics of the domestic SOC chip,improves the power outage sequence after online upgrade to further ensure the stability of the upgrade process.This method has been applied to a certain aerospace controller and can support the simultaneous upgrade of multiple boards,proving the convenience and reliability of the upgrade method and having certain engineering application value.
