How to verify the Lockstep core from S32K344

[Qingwen]

dear NXP engineer

                            how to verify the lockstep core from S32K344, I has been setup SAF in my S32DS ,

Can i use the SAF to verify lockstep function? Could you provide some specific methods or steps?

Best Regards

Hello,

Once you enable the lockstep it will be monitored by RCCU unit.

There is no method how to directly invoke lock step fault on the cores. I mean each core will execute the same instruction, but one with injected fault in execution directly.

Instead you can inject fault into FCCU to test reaction on the lockstep fault:

Please refer to the following thread for explanation:
