Is it possible to disable ECC on c55fmc (or in pflash) or it is enabled by default and cannot be disabled ?
Hi, ECC cannot be disabled and it is always enabled.
The only difference is in the suppressed error reporting on data flash with MPC57xx as described here, section 2.4.2:
ANxx - Error Correcting Codes Implemented on MPC5744P
However this way it works only with data flash, not code flash. In case code flash, reading or execution of data field affected by multi-bit ECC error causes bus error.
