今天用 Buildroot 编译文件系统烧写到开发板启动提示下面的错误
can't open /dev/ttyS0: No such file or directory
can't open /dev/ttyS0: No such file or directory
can't open /dev/ttyS0: No such file or directory
can't open /dev/ttyS0: No such file or directory
can't open /dev/ttyS0: No such file or directory
can't open /dev/null: No such file or directory
can't open /dev/null: No such file or directory
can't open /dev/null: No such file or directory
can't open /dev/null: No such file or directory
can't open /dev/null: No such file or directory
后面发现是内核没有选上 CONFIG_DEVTMPFS_MOUNT 的原因，配置上之后重新编译内核烧写到开发板就可以避免这个问题了
