Hi,
I am using IPC2, set by CPU 1 to let CPU2 know data ready to get it from shared memory. I am using IPC interrupt on CPU2 to do this. My problem is that even though I see IPCSTS.IPC2==1, PIEER1.INTX15==1, and CPU register IER.INT1==1,IFR is zero both (PIEIFR1.INTX15 and CPU register IFR.INT1). My interrupt initialization is as below. I am doing same initialization for IPC0 on CPU1. IPC0 is set by CPU2 to let CPU1 know of some data, and it is working. But I have problem on CPU2 for IPC2, I tried IPC1 same ... I would be grateful if you share your opinion.
Interrupt_register(INT_IPC_2, &TXFILL_IPC); // Register ISR for IPC Flag 1
Interrupt_enable(INT_IPC_2); // Enable interrupt
HWREG(PIECTRL_BASE + PIE_O_IER1) |= PIE_IER1_INTX15;
Interrupt_clearACKGroup(INTERRUPT_ACK_GROUP1);
Interrupt_enable(INTERRUPT_CPU_INT1);
// IER |= INTERRUPT_CPU_INT1;
EINT;
ERTM;
Thank you
