>>I don't how it's possible any one can Idea about that ?

Don't know, you've been asked multiple times for data from the chip, and not provided it

Perhaps also grab the initial content from the device that aren't working so that might be analyzed. Option Byte settings, and FLASH_SR reporting would also be instructive.

Hello,

Sorry for long delay on this topic. There is indeed no mention of Rev 2 in errata sheet. This must be corrected rapidly.

However, Rev Y and Rev 2 are controllers produced with exactly identical masks, but on 2 different production plants. (As it is the case with Rev Y and Rev 1 already).

I suppose the different behavior you have observed on your 2 samples might more be linked to Option bytes settings or something similar than to the Silicon itself.

Hope it could help.

Best regards,

Antoine
