How to make FCCU to fall into Fault state...??Because i want to check F_FFRR ( FCCU failure to react reset) in DES register

Hi,

You can use Fake fault inject via Noncritical Fault Fake (FCCU_NCFF) to trigger fault.

Enable the fault in FFCU_NCFEx register and set no reaction on this fault in NCFS_CFGx register. Then inject the fault.

Hi,

If you want to get into config state - YES.

And you must go to config state to configure FCCU.

And here is my example demonstrating FOSU reset.

Just copy it and you will trigger RGM.DES_FFRR
