In-program flash write fails
EE2Prom User module's flash block write returns error code -1 (protection error) on a production board with CY8CLED04D02 while the same program code is fine on Start Kits CY3267, CY3268 with CY8CLED04D0CD1 onboard. ISSP programming by MiniProg1 (Reset Cycle) is ok, without external power via USB. Olso I can't fall inside the FlashBlock library to find out more detailed error diagnose.
What should be done next, please?
