Hi Felix,

Really sorry for the late reply.

After digging deep in to the kernel code,I found out that the eMMC driver does not support write protection on the partition table.

Thank you for your response. I’ve encountered an issue with the eMMC partition table being corrupted. Is there an automatic recovery method for such damage?For example, is it supported to back up the partition table?

You can backup the partition table,using the sfdisk command in the LINUX kernel.For eg,to backup the partition table of eMMC,you can run the below command,will copy the partition table data to the txt file.

sudo sfdisk -d /dev/mmcblk0 > emmc_backup.txt
