Watchdog IRQ issue in Mac57d5MB

[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);

  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.

There is no attachment please check once again. And is it related to SIRC clk enable ? If yes then i have already enabled the clk as mentioned in previous mail . please check

[lukaszadrapa]

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.

[prashantsathe]

Yes, Problem is solved now.

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 ..
