RTOS/F28M35H52C: how could i set the M3 core ipc interrup function to receive c28 ipc interrupt?

I'm not sure I understand the question--can you give me more details? Which core is running to sys_exit? C28 or M3? Is the exit occuring when the M3 sets the IPC flag that is supposed to trigger the interrupt? Or at some other point?

Is the RTOS running on the C28? Is it TI-RTOS or some other?

thank you for reply, it run rtos in the m3, there is no-system;
in the m3 the code is
init_ipc()
{
IntEnable(INT_CTOMPIC1);
// IntRAMRegister(INT_CTOMPIC1,CtoMIPC1IntHandler);
IntRegister(INT_CTOMPIC1,CtoMIPC1IntHandler);
}

void CtoMIPC1IntHandler (void)
{
debug = 1;

// Acknowledge IPC INT1 Flag
HWREG(MTOCIPC_BASE + IPC_O_CTOMIPCACK) |= IPC_CTOMIPCACK_IPC1;
}

when run the IntEnable(INT_CTOMPIC1); the system have this error
Can't find a source file at "C:/ti/controlSUITE3.2.5/device_support/f28m36x/v202/MWare/driverlib/interrupt.c"

When you're debugging, do you ever see the CtoMIPC1IntHandler() run? How are you triggering the interrupt on the C28?

That error you're seeing is just CCS saying that it doesn't know how to find and display the interrupt.c file while debugging. It doesn't mean there's anything wrong with your code. There are a few ways you can fix it:

(1) Is there a locate file button on the screen where the error is displayed that allows you to tell CCS where to find it? That will make it go away.

(2) You can import the driverlib.lib project into CCS, rebuild it, and then rebuild your application--that will update the paths in the .out, so that CCS will be able to find them locally.

(3) You can also add the driverlib source files you're using (interrupt.c, etc...) to the project and then exclude them from the build. This will allow CCS to find them but since they're excluded they won't conflict with the .lib.

hi there as you say i inclucde the interrupt.c in my project and the function below can run ,but the system have printf info below
init （）
{
IntEnable(INT_CTOMPIC1);
// IntRAMRegister(INT_CTOMPIC1,CtoMIPC1IntHandler);
IntRegister(INT_CTOMPIC1,CtoMIPC1IntHandler);
}

Does the error message give any more information than that? Any details that say what the cause of the exception is?

If you single step through the code, on what line does the exception occur?

Thanks,
Whitney

init_ipc();
/* SysMin will only prnt to the console when you call flush or exit */

System_flush();

at the System_flush  the system will be error;

and i test to change the order

System_flush();

init_ipc();

the system will error at he BIOS_start()

so my question if i want to recvive the ipc interrupt from c28 by use a interrupt function ,can this be done in the rtos ???
in the c28 i config a timer to invoke a ipc interrupt CtoMIpcRegs.CTOMIPCSET.bit.IPC1 = 1 to signal IPC1 to M3;
how many ways to check the interrupt when m3 run the rtos ? thank u;

Okay, thanks for the additional information. It's definitely possible to get an IPC interrupt from the C28 even if you're using RTOS.

When setting up interrupts in SYS/BIOS you typically want to use a Hwi and let SYS/BIOS manage the interrupt for you. Have you done that in your cfg file? If so, you probably don't need to call IntEnable() or IntRegister() at all.

Whitney

thank you for reply, i am sure that i can revice the interrupt ,but i want the interrupt form c28 can invoke a callback function to handle the interrut

Were you able to make any progress?

Whitney

no , i did'nt set up a hwi , is there any document for the hwi?

hi Whitney, did not have progress
