LOCKSTEP Failure

[nirmal_masilamani]

Hello Team,

We are working on S32K344 and S32K358 for AEB application.
In that safety features, for lockstep failure (core 0 and core 1 result didn't match), we need to read FCCU data. For that we got to know, we need SAF package.

Is there any other way to know, lockstep failure.

Any register for reading FCCU data/ Lockstep failure?

Hello,

That is not true. You can read FCCU status registers without any driver packages.

Is there any other way to know, lockstep failure.

Simply read in code FCCu NCFS register to see the failure root cause.

NCF0 of Non-critical Fault Status (NCF_S0) register
