Dear Sir：
S32K148 Flash Configuration, 0x400~0x407 is set to 0x55, 0x40C is set to 0x6C.
After programming, is there a way to unlock and reprogram it?
Thanks
Hi@gary_yang
"0x400~0x407 is set to 0x55 and 0x40C is set to 0x6C" which means:
backdoor key is disabled(KEYEN = 01b) and Mass erase is disabled too(MEEN = 10b), which
means this chip can't unlock back to normal status by Mass erase or backdoor access.
