EEPROM emulation driver basically spreads programmed data content over the whole data flash in order to prevent wearing out of particular flash portions. It does not differ whether data content is still the same or not, because every write points to different place.</P></BODY></HTML> Tue, 04 Aug 2020 08:14:17 GMT https://community.nxp.com/t5/S32K/EEPROM-wear-down/m-p/1057170#M7071 davidtosenovjan 2020-08-04T08:14:17Z
