注意看这条报警记录：

其中有一句话比较重要：

STOP due to: Memory reset started automatically (power on not backed up )

大致意思就是：因为没有电源备份，所以导致 内存自动复位而进入 STOP 模式。

再然后，进入 LINK-UP 模式，与 CPU0 进行同步。同步结束后才会进入 RUN 模式。

我曾经就是通过拿掉保护电池 + 断掉两路电源的方式，让 CPU1 的内存自动复位。然后再上电向 CPU0 进行同步所有数据的（硬件配置、程序等待）。

至于你的 CPU1 为什么会出现这种非人为因素导致程序丢失的情况，只能依靠你自己去查找了。
