Hi John,

yes the "write enable" operation is performed at line 78 in "main.c" (for details, please, refers to line 46 in "myEPCQ16A_Driver.c" and, with more details, in "myFL_WriteEnable()" function at line 334 in "mySpiGenericFlashController.c").

About sector address (myEPCQ_USER_SECT_START) it is defined in "myEPCQ16A_Driver.h" and is "0x001F0000": it's not the flash location but the sector address in FLASH Memory space where I want perform my operations (Read, Write, Erase).

Thank you

Maurizio
