EXT4-fs (mmcblk0p1): couldn't mount as ext3 due to feature incompatibilities

这个错误提示表明你的 SD 卡分区文件系统是 EXT4，但是你尝试将其以 EXT3 的方式挂载。这是由于 EXT4 文件系统具有 EXT3 不支持的一些新特性导致的。为了解决这个问题，你可以尝试以下方法：

1. 卸载 SD 卡分区：

   umount /dev/mmcblk0p1

2. 尝试以 EXT4 方式挂载 SD 卡分区：

   mount -t ext4 /dev/mmcblk0p1 /mnt/sdcard

其中 /mnt/sdcard 是你想要挂载 SD 卡分区的挂载点，可以自定义。

如果以上方法无法解决问题，你可以尝试使用一些工具来修复 SD 卡分区的文件系统，例如 e2fsck。但是在使用这些工具时，你需要非常小心，以免误操作导致数据丢失。建议在尝试修复之前备份 SD 卡的数据。

~ # mount /dev/mmcblk0p1 /mnt/ EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)

这是执行了将/dev/mmcblk0p1挂载到/mnt/目录下的命令后的输出结果。该命令将/dev/mmcblk0p1上的ext4文件系统挂载到/mnt/目录下。在过程中，程序会输出一些信息，例如文件系统的类型（EXT4-fs），挂载模式（ordered data mode）和选项（null）。挂载后，您可以在/mnt/目录下访问/dev/mmcblk0p1上的文件和文件夹。

EXT4-fs (mmcblk1p1): unable to read superblock

This error message indicates that the file system on the specified partition (mmcblk1p1) could not be mounted because the superblock, which contains important information about the file system (such as the size, location and status of files), could not be read.

Possible causes for this error include:

1. Physical damage to the storage device
2. Corruption of the file system due to software or hardware issues
3. Incorrect partition table settings
4. Improper shutdown of the system or abrupt removal of the storage device

To fix this error, you can try the following steps:

1. Check the physical condition of the storage device and replace it if it is damaged.
2. Run a file system repair tool such as fsck to fix any corruption in the file system.
3. Check the partition table settings to ensure that the partition is correctly identified and mapped.
4. Avoid improper shutdowns and ensure that the storage device is properly ejected before removal.
