错误说明

将letter shell移植到ESP8266后，可以正常编译和烧录，但程序运行到 shellInit(&shell, shellBuffer, 512);后会无限重启

ESP8266运行时输出的日志信息：

有没有重启前的打印，我记得发生异常，重启前会打印出异常原因和调用栈的

最后有把栈和寄存器信息打印出来，用 idf_monitor 或者 addr2line 分析下调用栈，看看是在哪里挂掉的

根据官方文档：https://blog.csdn.net/espressif/article/details/102658110， PC寄存器的值为0x4000bdcb，【PC 寄存器值若为野指针, 例如 0x80001210, 可能是内存踩踏. 一旦踩踏到栈底的 PC, 形如 retw.n 就会弹出野指针.】

猜测可能是调用letter-shell初始化函数的时候的时候出现了指针调用的问题。

初始化时野指针，可能是命令表没有被编译进去，现在里面 esp idf 的例程不确定是不是适合 8266 最好看看 map 文件，确认下命令表是不是都编译到一块连续空间了
