[prashantsathe]

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);

#if 1

  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); //

Hi,

have you tried it in standalone mode without debugger? Debuggers usually automatically disable the watchdog in debug mode...

Sorry for late reply.

"Debuggers usually automatically disable the watchdog in debug mode." .. Yes, I have tried without debugger Also.

We have added a UART print statement in non debug mode . we are not getting any print on console.ahan
