Li,

The primary event ID for the CorePac is device-specific. Please take a look at the CorePac Primary Interrupts tables in both C6657 and C6678 data manuals.

For example, CIC0_OUT0 event has event number 102 in C6678 and number 22 in C6657.

Hi Steven,

I have try it, But i still have problem.

question is here:

(1)CIC0_OUT#NUM, I think the #Num = host id.

And we must to get GEM id from host id by CpIntc_getEventId.

And I think GEM id = CorePac Primary Interrupts.

Is it right?

(2)I know your example is right from data manuals,

I try to get GEM id by CpIntc_getEventId.(on 6657)

I have map system interrupt #156 map to host id #8

event_id = CpIntc_getEventId(8);

I think the event_id should be 30.(core 0,CIC0_OUT(8+20*n))

But the event_id = 74. It make me confuse.

Can you help me?

Best Regards,

Li,

Please make sure the RTSC platform file to be C6657 as we discussed in the other thread. Thanks.
