Need of Silicon Errata Sheet for these microcontrollers.....
PK20DX128VFM5(Pre-Qualified) & MK20DX128VFM5(Market Qualified)
Prequalified version MCU assembled FRDM-K64F(2 NOs-REV C) is Not working for any code that has been locally builded.
The same builded file is working fine with Market qualified MCU assembled FRDM-K64F(1 NO-REV E)
But sample code from Demo package provided by Freescale is working fine on Both REVC and REV E Boards.
