We need to configure the ECC for the Program flash Memory,
Please share reference and application code for configure the ECC for the Flash memory
I tried below steps
1) Set FERCNFG with 02 in the Main
2) Set the Bit FDFD to check whether interrupt generates or not.
I am not able see Status bit is getting changed and Interrupt is not generated
Thanks and regards
Once FERCNFG[FDFD, DFDIE] are set, do you read the flash? This should assert the DFDIF flag.
The interrupt has to be enabled in NVIC though.
we are running the program from flash, which means flash access should be done with the program execution right
Yes, that is correct.
It might take a few instructions before the flag is set.
This is because of the core architecture.
If you want the flag to be asserted immediately, disable the write buffer:
S32_SCB->ACTLR |= S32_SCB_ACTLR_DISDEFWBUF_MASK;
After I set the FDFD flag, i am polling for the bit DFDIF in FERSTAT and it never set.
Am i missing something ?
I don't have access to the S32K148 EVB right now, unfortunately.
But I tested in on other S32K1xx parts and it works as expected.
Can you test it with this simple code?
