官网提供最新版rt linux 4.14.79 root账户登陆不正确

您好，/etc/securetty 文件里面有ttyS0的，文件见附件，麻烦再帮忙看下，谢谢！

5732.securetty.rar

你使用的是官方的开发板吗？如果是官方的开发，一般都可以直接下载编译好的镜像，镜像说明有告知登录账户和密码

您好，

     我这边是自己公司按照TI开发板做的板卡，我下载了TI的SDK开发包，修改了设备树文件，文件系统用的是SDK中的arago-base-tisdk-image-am437x-evm.tar.xz没有修改，系统正常启动就是root登录不进去，你说的说明有告知登录账户和密码我在SDK中也没有找到，麻烦能告诉我下登录账户和密码说明在SDK哪个位置吗，非常感谢！

您好，目前不是编译的问题，系统能正常运行起来就是登录不进去，串口打印的信息如下：
