I am currently developing on KL15 microcontroller, Bareboard without PE. As required, I would like to enable watchdog timer for security reasons. Right now I am running a small testing program with watchdog timer enabled at the starting of the main and do not feed anything to it. I expect that the program resets itself frequently. However, the program runs per normal. It looks like the watchdog is never enabled. I am attaching my code for reference. Hope I can get some help in clearing my doubts.
Thank you.
void __init_hardware()
{
SCB_VTOR = (uint32_t)__vector_table; /* Set the interrupt vector table position */
// Disable the Watchdog because it may reset the core before entering main().
SIM_COPC = KINETIS_WDOG_DISABLED_CTRL;
}
void WDG_Enable()
{
SIM_COPC = (0x08 & 0x0F); // Enable the clock and the timeout count
}
void SysInit()
{ /* Enable the COM Port UART with minimal settings */
UART0Init(9600);
UART0HWFCPinInit();
UART1Init(9600);
UART1HWFCPinInit();
/* Initialize the WatchDog */
WDG_Enable();
COMSendString("\r\nWDG Enabled");
}
void EnvInit()
{
/* Create the tasks here */
CreateComTasks((configMAX_PRIORITIES-2)); // Create the COM task
CreateModemTask((configMAX_PRIORITIES-2)); // Create the Modem Task
CreateUpdateTask((configMAX_PRIORITIES-1)); // Firmware Update task with the default source as COM port
/* Create the Semaphores related with UART1 and UART0 */
CreateUART1Sem();
CreateUART0Sem();
}
int main()
{
/* Initialize the peripherals and GPIO in here */
SysInit();
/* Initialize the environment */
EnvInit();
vTaskStartScheduler();
return 0;
}
