Hello, @Harish_R

Thanks for your post.

Would you mind sharing your eMcem configuration window? and also the SAF version used?

Hello, @Harish_R

Thanks for your reply.

May I know if you have placed your own NMI handler to the following part?

Hi @chenyin_h

yes, i have placed it accordingly.

when is it supposed to hit.? when NMI fault is triggered right?

in EB we configure. NMI Notification Function.

Hello, @Harish_R

Thanks for your reply.

I mean that since in your EB configuration, the NMI handler set is eMcemUserNmiHandler, and by default in SAF, the handler is NMI_Handler, may I know if you have changed it accordingly?

Hello, @Harish_R

Thanks for your reply.

What I mean is, by default, the NMI handler is NMI_handler, which is defined in the vector table, and from your settings, the NMI handler is eMcemUserNmiHandler, how you put your own NMI handler to make it called?
