Previously I'm using MKE14Z256VLL7 MCU on my target board. Now I switched to MKE14Z128VLL7 MCU to reduce the cost. However I can neither program it nor debug it.


I'm using MCUXpresso IDE v10.0.0_344 and P&E multilink universal for debug and P&E cyclone universal programmer for programming.


They worked fine for MKE14Z256VLL7 MCU but not for MKE14Z128VLL7 MCU.


For debugging, I got an error as follows:


For the programming, I got an error $00001003, blank check operation failed.


What could be the problems?
