Hi,
I would like to implement the watchdog feature on DSS.
I also reference the sample code in the watchdog driver folder.
When watchdogInit() is initialized, the watchdogCallback() start to work.
My question is that why watchdogCallback() is working, it triggers the ESM ?
And then, the softreset is triggered.
Is there any other configurations missing on DSS ?
Thanks

Implementation:
====================================================================
On DSS:
static void watchdogCallback(Watchdog_Handle handle)
{
gWatchdogInt++;
if (gWatchdogInt > 200)
{
System_printf ("Debug: Application - Watchdog Driver callback for NMI received\n");
//DebugP_assert(0);
}
return;
}
static int32_t watchdogInit(void)
{
Watchdog_Params watchdogParams;
/* Initializa the Watchdog driver */
Watchdog_init();
/* Initialize the Watchdog driver default parameters */
Watchdog_Params_init(&watchdogParams);
watchdogParams.resetMode = Watchdog_RESET_OFF;
watchdogParams.callbackFxn = watchdogCallback;
watchdogParams.debugStallMode = Watchdog_DEBUG_STALL_OFF;
watchdogParams.windowSize = Watchdog_WINDOW_100_PERCENT;
/* T-expire = (preloadValue+1) x 2 ^ 13 / RTICLK1 ; preloadValue=0~4095 ; RTICLK1=200MHz */
watchdogParams.preloadValue = 4095; //150ms
watchdogParams.socHandle = gMmwDssMCB.socHandle;
watchdogParams.esmHandle = esmHandle;
/* Open the Watchdog driver */
watchdogHandle = Watchdog_open(0, &watchdogParams);
if (watchdogHandle == NULL)
{
System_printf ("Error: Watchdog Driver Open failed\n");
return -1;
}
return 0;
}
On MSS:
static void DSPNotifyMSSCallback(void* arg)
{
gWatchdogDspInt++;
CLI_write ("\n\rsoft reset (%d)\n\r", gWatchdogDspInt);
SoftSysReset();
return;
}
====================================================================
