I noticed whenever we used sd card no error is coming if we use emmc most of time Input/Output error is coming.
eMMC some partition is locked.

Why only emmc we getting Input/Output error ?
How to solve ?

Thanks & Regards


This error is normal because for eMMC, this is extra partition for boot can not be accessed directly:

/dev/mmcblk0boot0 - BOOT0 partition
/dev/mmcblk0boot1 - BOOT1 partition
/dev/mmcblk0rpmb - RPMB partition

Check this thread:

How to solve the issue ?

Thanks & Regards

It is an issue with upstream systemd, said to be fixed in later version:

To “solve” the issue, would need to update to a version of systemd that has this fix.

Another option maybe to disable the systemd feature.

Hi aaditya,
Thank you for your reply.
Why this issue with only eMMC ?
SD card no issue.

Its because eMMC can contain some special partitions as @jack explained, which systemd didnt handle correctly.

SD card dont have those special features.

Kind regards
