Watchdog IRQ issue in Mac57d5MB

Hi,

I am trying to get an Irq from watch dog timeout but unable to do so. Could be please point out my error.

Below is the code snippet.

void watchdogtest()

{

/*Enable watch-dog*/

enable_irq (INT_SWT_0 - MAC57D54H_FIRST_USER_IRQ);

route_interrupt (INT_SWT_0 - MAC57D54H_FIRST_USER_IRQ, 0x03);

SWT_0.SR.R = 0x0000c520;

SWT_0.SR.R = 0x0000d928;

SWT_0.CR.B.WEN = 0;

SWT_0.TO.R = 0x500;

SWT_0.CR.B.ITR = 1;

SWT_0.CR.B.FRZ = 0;

SWT_0.CR.B.WEN = 1;

SWT_0.CR.B.SLK = 1;

uPrintf("In a While Loop...\n");

while(1); //

}

vector 122 is corresponds to SWT0

#define VECTOR_122 default_isr_test /*default_isr_test is dummy function to test an IRQ*/

clock SIRC is enabled .

and below is the register value corresponding to SWT0

Thanks in advance,

Hi,

there's simple example in this thread:

SIRC clock

It could solve your problem.

BTW, if you are talking about enabling SIRC clk then we have already have below code at start up which is used to enable the SIRC.

/* Turn on FXOSC, SIRC and SXOSC - can integrate this into enable PLL step - leaving separate for now during testing */

MC_ME.DRUN_MC.R = 0x00130030;

MC_ME.MCTL.R = 0x30005AF0;

MC_ME.MCTL.R = 0x3000A50F;

let me know if it is different ..

Can you already see the attachment in my previous post? It seems that it is not visible immediately...

The example is related also to watchdog.

Not sure what's wrong. I can see that also on computer connected to public net even if I'm not logged in. Is this link working on your side?

I will try to attach it again to this post with extension renamed from zip to aaa. Maybe it's caused by your firewall or something like that.
