Hello Uthaya Kumar,

May I know for what purpose you are reading MCU_PORZ?

You want to know if the device is Resetting or not.

Are you using isolation, like isolating the MCU core from the main domain?

Do you want to read MCU_PORZ status from which core, either A53 or R5F?

Regards,

S.Anil.

Hello Uthaya Kumar,

When you monitor below Register and the 0th bit, it exactly tells about the status of MCU_PORz.

Can you please confirm in Linux Core if you are able to read the proper status or not from the below Register after controlling MCU_PORz Hw pin ?

Regards,

S,Anil.
