updateerror是什么意

意思是更新错误，例如：

1、The pre-update snapshot would permit reverting if a significant update error occurs， and the post-update snapshot could be used for report writing during the next quarter.如果发生严重更新错误，允许还原更新前快照，而更新后快照用于报告下一季度的写入。

2、In particular， it can effectively prevent the embedded system from failing to start by update error， which will have a high practical value and can effectively reduce the embedded software development and maintenance costs.尤其能够有效地防止嵌入式系统固件更新失败后，系统无法启动的情况，能有效地降低嵌入式软件的开发和维护成本，将具有较高的应用价值。
