启动的时候串口初始化失败，panic'ed (StoreProhibited). Exception was unhandled

[Mars.CN]

重新编译了Micropython提供的源码，发现在初始化串口的时候报错
Guru Meditation Error: Core 0 panic'ed (StoreProhibited). Exception was unhandled.

这是什么原因造成的？

[Mars.CN]

怀疑问题出在分区表上，用的是果云的开发板，他用的是ESP32F，我竟然查不到这块板的信息。
怀疑他用的Flash是2M的，而Micropython中ESP项目的分区表应该是照着4M做的
从这个方向入手，看看能否解决问题
