Per this post: robustness of DS/VS in NVRAM
I am using serial flash, and it losts VS data when power is corrupted.
Does the automatic WP control apply to only DS?

VS (Volatile Section) = Data to be modified by the application. Ex. paring information or the application’s private data.
DS (Data Section) = Application’s executable binary image.
If the Serial FLASH loses power during a write cycle, then VS data could be lost.

VS uses checksums. Regardless, some data (that is being written) could be lost during a power outage.

mwf_mmfae,
Could you please give me more details?
I can not understand fully why the data in VS can be lost due to power corruption like short.

Hello EY AN,
If the Serial FLASH loses power during write cycle then the data will be lost.
Thanks,

JT,
I think so, but DS data was not lost although VS was lost.
