Maybe some power or SI issue at the Flash EEPROM?

The firmware has a 5 ms timeout for page writes (3 ms max on the W25Q16)
The erase timeout is 3 seconds (400 ms max on the W25Q16)
so that should not be an issue.

I'll look into the power supply.

SI = serial input ?

Thanks again.

SI = Signal Integrity (fussiest signal would be the clock)
