It wasn't Getty, it was something that was built into their application. and then but then if their application for whatever reason failed the next step in the init process would be just run a shell.

这不是Getty，而是他们的应用程序中内置的东西。然后，如果他们的应用程序由于某种原因失败了，那么初始化过程的下一步就是运行一个外壳程序。

But I found a point later during the init process where poking the serial flash device caused the init process to fail and give me exactly what I wanted out of this. A root shell on the device.

但后来我在初始化过程中发现，戳到串口闪存设备会导致初始化过程失败，并从中得到我想要的东西。设备上的根外壳。
