At present, our J6 project USES 8G EMMC. At present, we set the system file to read and write by default. During the process of testing switch or reading and writing to the file, the system file will become read-only.
Hi
Can you attach the complete console logs
Please check if you see any errors being reported for IO operations to EMMC
You can get the complete kernel logs using the command below
# dmesg
1、The attachment is the log of the exception #dmesg；
2、 if you see any errors being reported for IO operations to EMMC？What is this? What IO？
3、Modify the J6 system fstab file to mount the root directory as read-only after the system is started. After repeatedly running up and down for a period of time, there will be an error when executing "fsck.ext4-p /dev/mmcblk0p1". The information is as follows：
root@dra7xx-evm:~# fsck.ext4 -p /dev/mmcblk0p1
rootfs contains a file system with errors, check forced.
rootfs: 3470/7168 files (0.0% non-contiguous), 21493/28672 blocks
What are the possible reasons for this, and how do you find them in terms of software and hardware?

HI
is the issue seen on multiple boards or is it specifically seen when you run your tests on a particular board
You may additionally check if the issue goes away on a subsequent reflash of the emmc and clean restart of the system.
If you are rebooting the board several times as part of your testing, ensure that the system shutdown is graceful, then the contents of the filesystem will stay consistent.
If you are asynchronously shutting down your board, you may have to run additional fsck type checks to ensure that the filesystem contents are not corrupted from a previous shutdown
HI,
1、is the issue seen on multiple boards or is it specifically seen when you run your tests on a particular board?
repaly:All the boards can be reproduced; Follow this experiment: power up and down frequently, and read and write to EMMC
2、You may additionally check if the issue goes away on a subsequent reflash of the emmc and clean restart of the system
repaly：The problem will not go away after reading only, unless you use the following command to fix it:fsck.ext4 –p /dev/mmcblk0p1；
3、If you are rebooting the board several times as part of your testing, ensure that the system shutdown is graceful, then the contents of the filesystem will stay consistent.
repaly：System shutdown reasonable how to understand? We start at 30S and close at 30S；
4、If you are asynchronously shutting down your board, you may have to run additional fsck type checks to ensure that the filesystem contents are not corrupted from a previous shutdown
repaly：How to understand asynchronously shutting down your board?How is the normal shutdown software handled？
We will now mount the following program at boot time, forcing it to be read-only, but the following error will still occur："rootfs was not cleanly unmounted, check forced."（Mount changes place：/etc/init.d/checkroot.sh）
This error occurred earlier："rootfs contains a file system with errors, check forced."
Help to analyze the causes? THS！
Hi
you need to ensure that you following one of the following
1. Use shutdown command to ensure that the file system state is cleanly updated as against an abrupt power down of the board
2. If as part of your tests, if you have any writes to the file system, ensure you either flush or unmount the filesystem cleanly before powering down
if you do not gracefully shutdown, filesystem state can be corrupted and will require fsck to rescan and fix errors
HI：
1、We found that there were also errors in constantly switching on and then frequently reading and writing; There is no power cut；
2、If all power is suddenly cut off, is there no way to process the data before the cut off？
3、We now find that frequent reads and writes to media files are fine, while errors occur to system files；
What is the difference between the two files？
4、We will now mount the following program at boot time, forcing it to be read-only, but the following error will still occur："rootfs was not cleanly unmounted, check forced."（Mount changes place：/etc/init.d/checkroot.sh）；We wanted to start before changing read-only, but there was still an error。While we can burn the new image file (change read-only) without any problem, what's the difference
Hi
to simplify the discussion, anytime you shutdown the system (power abruptly going off, you switching off the power switch), the filesystem state can be left in unclean state.
If instead we follow the right steps to gracefully shutdown (typically using the shutdown command or similar), then the applications that were running are stopped first and any dirty filesystem updates are flushed to the disk before disabling the storage device
If you are not gracefully shutting down, it is possible that the filesystem state on the next reboot is scanned for and any errors identified flagged. You then run fsck to correct these
Depending on your end application and criticality of the data, you may need other external means(on board capacitor to keep the board powered on for short while longer to allow for graceful shutdown)
On difference between user data vs system files, i dont have specific feedback. It is possible that some scripts in the filesystem where running and accessing content from the filesystem while the shutdown happened
Overall, if you are not doing a graceful shutdown it is inevitable that we see errors being reported on reboot.
