about [SM_119]:" The Flash memory ECC failure reporting path should be checked to validate if detected ECC faults are correctly reported. [end]"
Theimplementation hint :"The flash memory ECC fault report check is executed in software".
I would like to understand what does the implementation hint mean.
In my application I enable the double bit fault detect interrupt and then I force an ECC error:
FTFx_FERCNFG |= FTFx_FERCNFG_DFDIE_MASK;
FTFx_FERCNFG |= FTFx_FERCNFG_FDFD(1);
uint32_t tempvar = (uint32_t)*((uint32_t*)(0x4));// Reset vector address here
This triggers the ecc controller and generates the expected interrupt. In the FTFC_IRQHandler, i relocate the callback (so no more ECCs are generated) for checking if the ECC was a real error or a test.
In case of error if no FTFx_FERCNFG_FDFD(1) was present in FTFx_FERCNFG i enter in a safe state.
is this considered a ECC fault report check or am I out of track?
