I'm currently working with TMS320C6678 simulator in CCS 5.5. I would like to provide communication between CORE0-3 using MessageQ (for transport data) and Notify (for synchronization). In my case Ipc.procSync is set to Ipc.ProcSync_PAIR. CORE0 is master and other cores works as slaves. Code in task of the CORE0:
...
while (Ipc_attach(1) < 0) { Task_sleep(1); } Notify_registerEvent(1, INTERRUPT_LINE, EVENTID, (Notify_FnNotifyCbck)cbFxn, NULL); Notify_registerEvent(2, INTERRUPT_LINE, EVENTID, (Notify_FnNotifyCbck)cbFxn, NULL); //exception Notify_registerEvent(3, INTERRUPT_LINE, EVENTID, (Notify_FnNotifyCbck)cbFxn, NULL);
...
Code in CORE1-3:
... while (Ipc_attach(0) < 0) { Task_sleep(1); } Notify_registerEvent(0, INTERRUPT_LINE, EVENTID, (Notify_FnNotifyCbck)cbFxn, NULL); ...
I have only one task per core. My problem is with Notify. My code works good with two cores (only one Notify_registerEvent in CORE0). If I would like to create communication with three or four cores I get exception after register Notify between CORE0 and CORE2. Exception:
[TMS320C66x_0] ti.sdo.ipc.Notify: line 338: assertion failure: A_notRegistered: Notify instance not yet registered for the processor/line
xdc.runtime.Error.raise: terminating execution
Here is my cfg file. It's the same for all cores.
var nameList = MultiProc.getDeviceProcNames();
MultiProc.setConfig(null, nameList);
var System = xdc.useModule('xdc.runtime.System');
System.extendedFormats = '%$L%$S%$F%f';
var SysStd = xdc.useModule('xdc.runtime.SysStd');
System.SupportProxy = SysStd;
/* Modules explicitly used in the application */
var Notify = xdc.useModule('ti.sdo.ipc.Notify');
var MessageQ = xdc.useModule('ti.sdo.ipc.MessageQ');
var Ipc = xdc.useModule('ti.sdo.ipc.Ipc');
var HeapBufMP = xdc.useModule('ti.sdo.ipc.heaps.HeapBufMP');
var MultiProc = xdc.useModule('ti.sdo.utils.MultiProc');

var BIOS = xdc.useModule('ti.sysbios.BIOS');
BIOS.heapSize = 0x8000;
var Task = xdc.useModule('ti.sysbios.knl.Task');
var tsk0 = Task.create('&tsk0_func');
tsk0.instance.name = "tsk0";

var SHAREDMEM = 0x0C000000;
var SHAREDMEMSIZE = 0x00200000;
var SharedRegion = xdc.useModule('ti.sdo.ipc.SharedRegion');
SharedRegion.setEntryMeta(0,
{ base: SHAREDMEM,
len: SHAREDMEMSIZE,
ownerProcId: 0,
isValid: true,
name: "DDR2 RAM",
});
var timer0Params = new Timer.Params();
timer0Params.instance.name = "timer0";
timer0Params.intNum = 9;
timer0Params.period = 10000;
Program.global.timer0 = Timer.create(-1, "&timer_interrupt", timer0Params);
My configuration is as follow:
IPC: 1.24.3.32
BIOS: 6.33.6.50
MATHLIB C66x: 3.1.0.0
