我的设备（CCTV 解码器）正在自行重启，因此无法使用 LAN 电缆登录。它只有 RS232 端口，没有 VGA 和键盘/USB 端口（嵌入式 PC）。
我连接了RS232交叉电缆并使用了Teraterm，我进入了设置模式。我可以在其中看到所有文件和目录。我无法以 root 用户身份编辑任何文件/文件夹。但我可以通过 telnet 对普通设备进行远程编辑。我不知道背后的原因。
以下是日志，请帮我解决问题。

答案1
它在日志中多次明确表示“只读文件系统”。这就是为什么您无法删除文件，即使是root.
答案2
您可以尝试对文件系统进行 fsck 并重新启动。由于在 fsck 自动模式下无法恢复的错误，文件系统可能已挂载为只读。
一定要这样做：
mount
这将向您显示已安装的文件系统和相应的块设备。查找根文件系统，即：
/dev/sda1 on / type ext4 (rw,noatime,errors=remount-ro,discard)
设备（即 /dev/sda1）可能与您的情况有所不同。在挂载为 / 的设备上对文件系统进行 fsck
fsck -y /dev/sda1
并重新启动。
答案3
软件映像已损坏，或者硬件行为异常。我看不出任何明显的原因。这不是那种可以通过互联网调试的问题，您需要自己进行调查。
重启可能是由于：
- 有缺陷的硬件；
- 有缺陷的软件（可能在内核中，或者至少由内核错误复合）导致重新启动；
- 有缺陷的软件（可能在内核中，或者至少由内核缺陷复合）会导致错过看门狗的截止时间。
您无法修改文件，因为文件系统是以只读方式安装的。可能的原因有以下几种：
- 文件系统应该以只读方式挂载——尝试
mount -o remount,rw /； - 文件系统应该通过启动脚本以读写方式重新挂载，但启动脚本有错误；
- 由于检测到错误，文件系统被重置为只读。
查看内核日志（ 的输出dmesg）以获取更多线索。
调试的主要途径有：
- 将启动日志与已知良好的设备进行比较。
- 查看内核日志。
- 使用调试器分析重新启动。
如果您不想调查问题所在，请重新刷新已知良好的固件映像，然后重试。
