ECC Flash Error

How to generate an interrupt notification upon the report of an ECC flash error,?.

Is there any configurations available in EB Tresos for this?.

Any single-bit ECC errors are automatically corrected, and any double-bit ECC errors are reflected onto FERSTAT[DFDIF] flag at the read access from Data Flash or Program Flash. This double-bit ECC error is reported by bus fault/hard fault handler. There isn't any configuration for report the ECC flash error in EB Tresos, unfortunately.

Best Regards,

Nam

When will the double bit ECC error for Flash is set?. Will it set if there is a checksum fault in flash?.

Hello,

You can refer to here: https://community.nxp.com/t5/S32K/S32K-ECC-error/m-p/878734 and here: https://www.nxp.com/docs/en/application-note/AN12522.pdf Basically, the ECC will be reported when the FLS read failed while checking the checksum value.
