LAUNCHXL-F28379D: Task_Sleep running into ILLEGAL_ISR

ILLEGAL_ISR can sometimes be an indicator of a stack overflow. Can you check for signs of a stack overflow? ROV usually tell if you there has been one.

Also, as I noted in your other thread, you don't want to call InitPieVectTable() in your application. Instead of calling ILLEGAL_ISR(), I would expect it to call a SYS/BIOS Hwi module error ISR instead.

Hi Whitney,

I am unable to get the ROV working, below is the error displayed

#315 has the below line

And with InitPieVectTable() not being called, I cannot get past below line

It gets stuck in below assembly code and does not execute my tasks

I think that address where you're ending up is in the boot ROM. You seem to be getting a reset. Can you look at the reset cause register (RESC) in the CCS Registers View and see what it says?

Not sure what's going on with ROV. Can you try ROV Classic instead?

Whitney

RESC is as shown below

The Watchdog timer is causing the RESET.

ROV Classic is working, what exactly should I be looking at in the ROV Classic to find the stack overflow?

Have you disabled the watchdog in your code? You can have SYS/BIOS do it for you by configuring the Boot module to do it. You could also call the C2000Ware function that does it. You should see a call to it in InitSysCtrl().

In ROV under the BIOS category, there should be a "Scan for errors" tab that should be able to show you if it has detected a stack overflow among other errors.

Whitney

Yes, even when watchdog is disabled in

SYS/BIOS -> Boot.disableWatchdog = true;

and 

C2000Ware-> DisableDog();

The code runs into bootROM, if InitPieVect() is not called.

ROV isn't showing any errors in the Scan for Errors sections

If InitPieVect()  is called in my init, then I have my Task1 executing within which I have a Task_sleep(10). The Task_sleep makes the Task1 go into BlockedState

and then Task2 starts running within which I again have a Task_sleep(10), this again causes Task2 go into BlockedState

Then the SYS/BIOS's IDLETask starts running and within that when

            Task_SupportProxy_swap((Ptr)&prevTask->context,
                            (Ptr)&curTask->context);

"lretr" line within TaskSupport_asm.s28 (TaskSupport_swap(oldSP, newSP) function) leads to ILLEGAL_ISR

My Tasks are as below

Void Task1(void)
{
    for(;;)
    {
    	Activity_X();

    	Task_sleep(10);
    }
}

Void Task2(void)
{
    for(;;)
    {
	int i;
	for(i=0; i<5; i++);

	Task_sleep(10);
    }
}

Rashmitha,

Whitney is currently out of the office, returning next Monday October the 4th.  You should expect a reply back when she returns.

Best,

Matthew
