大家好，最近在尝试移植openwrt到我自己的S3开发板时遇到了一点问题，我自己的开发板使用的是UART1 PG6 PG7两个管脚作为终端接口的，通过板载的CP2104转usb直接连接电脑，且仅此一个能连出的串口。具体现象如下：
u-boot引导正常，在引导过程中提示按任意键时按下键盘能进入u-boot的命令行。
内核引导正常，但是引导后不接受任何输入的命令或者回车按键。
日志如下：

请问该如何修正这个问题？
离线
自己解决了，目前的解决办法是进入failsafe模式打开 /etc/inittab文件
修改ttyS0::askfirst:/usr/libexec/login.sh
为ttyS1::askfirst:/usr/libexec/login.sh
