Hi everybody,

is there any new knowledge about this problem?

I testet Winbond W25Q128JVEIQ flashes and got the same problem. I soldered capacitors (10pf 0805) between the Data lines and ground, on some boards this solution work fine but not at all.

So i changed to Cypress S25FL128SAGNFI01 with this flash device all boards run without capacitors, but not stable.

Every 10 times the configuration fails.

Does anybody know a flash device with WSON-8 (8x6mm) package that runs reliable?
