FlashDisk getting erased if any abrupt power OFF

We are using IMX6DL 510MB with WinCE7 with latest OS versions.

When some abrupt power off due to no electricity, FlashDisk is getting erased.
We are facing this problem with many of the deployed devices. We are facing this problem to the devices deployed since last 1 year. Earlier deployed devices not facing this issue.
Is it due to new eMMC source you are using?

Please suggest what to do to resolve this problem.

hi @kshah,

Please confirm your Colibri iMX6DL 512MB version (eg 1.1A, 1.1B) and your CE OS (latest is 1.8).
Do you see an empty flash disk after reboot or FlashDisk itself is not visible?

Yes. We see empty flash disk after reboot.
version number not known. But below are device serial ID. I hope you can trace out version number.

Hi @kshah,
These serial number belongs to Colibri iMX6 DualLite 512MB V1.1A.
There was a change of eMMC from V1.0A to V1.1A.
Please help us to reproduce the issue.
Was your application doing some write operation to flashDisk at the time or failure?
Did it happens randomly after reboot?
Any other condition where we can see the issue?

As these devices are deployed on field, I could not receive above required details.
Generally, we write to SQLite database and to csv files.
I’ll try to reproduce the issue at our end by writing data to these. And will get back to you.
