Let me name some possible reasons of FLASH non-correctable ECC error reason (not necessarily related to EE handler):</P><P>- Unexpected reset during flash erase or flash program operation</P><P>- Wear out of particular flash sector = number of program/erase cycles that device’s flash is capable to withstand is exceded (in practice, real endurance is greater than specified minimum).</P><P>- Over-programming of particular flash area that is programming without erasing. It is basically software fault.</P><P>- Soft error (radiation, electro-magnetic interference, or electrical noise) during reading or executing from flash memory</P><P>- In general fault due to damage caused by running the device out of spec whatever way.</P><P>- and finally FLASH ECC error may be intentionally generated by ECC error injection.</P></BODY></HTML> Wed, 23 Sep 2015 06:55:19 GMT https://community.nxp.com/t5/MPC5xxx/MPC-5604C-EE-Driver/m-p/399835#M662 davidtosenovjan 2015-09-23T06:55:19Z
