S32K312 FCCU

[rameshnairmetallic]

I would like to know a simple way to configure FCCU on S32K312 to detect (not inject) any RAM or Flash errors and report them. I can read the FCCU registers periodically to check if there are any errors. Is this possible at all?

Is it possible to configure the FCCU to detect Interrupt line stuck at fault?

DOes the variant S32K312 have the Safety modules mentioned in the manual.

Hello,

the simplest way is to directly configure FCCU via FCCU registers.

Once there is any RAM of Flash error reported by memories, it will be latched in FCCU status register.

Depending on the FCCU configuration you can trigger:

1. reset

2. interrupt

3. no reaction

If the fault is enabled and the Alarm interrupt it triggered you can read in ISR the root cause of the fault and take appropriate action.

Basically you don't need any driver as it is simple static configuration of few registers.

For more details you can refer to functional description chapter in FCCU in reference manual.

Best regards,
