SYSBIOS 6.32 and use of a watchdog

Goodmorning,

I'm trying to use a watchdog with my MSP430f5438. But I have some problems with SYSBIOS and watchdog interaction: my application stop working if I disable "the watchdog disabling". Are there any resources o user manuals to give me an example of SYSBIOS/Watchdog use?

Thank you so much,

P.S. here is my source code

void main(){
 
     /* use ROV->SysMin to view the characters in the circular buffer*/
    WDTCTL = WDTPW + WDTHOLD;
     
    System_printf("enter main()\n");
    Led_Init();
    Led1_On();
    Led2_Off();
 
 
    CLOCK_XT1_Init(MCLK+ACLK+SMCLK);
    CLOCK_FLL_Init(MCLK+SMCLK);
 
    Calendar_Init(defaultTime());
    RTC_startClock_();
 
    P11DIR = P11DIR | 0x02 | 0x04 |0x01 ;            //set P11.1 & P11.2 as output
    P11SEL = P11SEL | 0x02 | 0x04 |0x01 ;            //set P11.1 & P11.2 as MCLK/SMCLK/aclk function
 
    UART3_Init(ACLK, 9600);
    USB_write_string("Start!\n\r\0");
 
     WDTCTL = WDTPW + 0x0000;
    Delay(1500);
    value = 1;
    WDTCTL = WDTPW + WDTHOLD;
 
    USB_write_string("End!\n\r\0");

}
