A C6678 IPC interrupt question

fan si ding

Hi all,

I meet a problem with the IPC interrupt, i writed IPCGRx to set up a interrupt to corex.

when i set a specific vector id except for the 4th vector id, the target core will enter twice interrupt ,

i have check the IFR register , the bit Corresponds to the 4th vector id will always be set up regardless of the specific vector id i used after i writed the IPCGRx of the target core , i don't know why ? can anyone help?

Thanks ,

Hi,

Have you connected event#91 - IPC_LOCAL to one of the core interrupts?

Thanks,

Hi,

Yes,i have.

The problem is when i set a specific vector id except for the 4th vector id, the target core will enter interrupt twice,

which is not expected.

thanks ,
