SAF eMCEM FCCU NMI handling

[Harish_R]

Hi,

i have configured the NMI reaction in eMCEM module for particular fault. but im not sure how test it. 

have configured NMI handler function. but when fault has been injected the NMI handler doesn't hit / execute.

if someone could drop some hints. it would be helpfull.

Regards,

Harish R

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?

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.

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