After the communication serial port is powered on, it can be used as a debugging serial port

jetson nx jetpack4.6

我们自己做的nx载板，硬件开发工程师说/dev/ttyTHS0是通信串口，
We made our own NX carrier， The hardware development engineer said /dev/ttyTHS0 is a communication serial port,

然后我刷的官方镜像，没有做任何处理
Then I brushed the official image without any processing，

当系统上电后， /dev/ttyTHS0输入用户名和密码居然能登录，我该如何设置，让这个设备仅仅作为一个通信串口使用呢

When the system is powered on, /dev/ttyTHS0 enters the user name and password and can actually log in. How can I set this device to be used only as a communication serial port

有人说我需要开机禁掉login这个进程，我认为不是这样
Some people say I need to disable the login process,I don’t think so

I don’t know how to configure it

hello 392415830,

please try to disable nvgetty, for example, $ systemctl disable nvgetty
you should also reboot the target for confirmation, thanks
