Hi,
Kindly provide the information for how to configure DDR in S25HS01GT memory model.
Hello. I have a question about S25FS512S(quad spi flash memory).
It has been used to 4 years in our test board. These hasn't been a problem for years.
Suddenly, the programming error have begun to occur frequently these days.
Specifically, when configuring the no-volatile memory in S25FS512S, the programming error is occurred.(SR1NV bit6, P_ERR).
To Recover from the error, I sent CLSR command to flash.
However, the programming error occurs immediately after recovery.
so, how can I recover it?

I am looking for help on identifying the part marking on S25FL256SAGNFB003. The part marking on the part is: FL256SABF00.
I have found a part marking decoder, but it does not identify this specific part but only others.
I would like to make sure I have the right part in my stock.
thank you for the help in advance.
