CCS/TM4C123GH6PM: hibernate mode and lab6 from TM4C123G workshop

Tool/software: Code Composer Studio

Hello,

I made a custom TM4C123 board, and I managed to program it by using another launchpad as a JTAG adapter.

In my board, there is a battery that supplies the VBAT, and I also managed to get RTC working as well.

Now i am trying to test the hibernate module. I have a wake button connected as specified.

I imported the lab6 project as specified with CCS Version: 8.0.0.00016 

Here is the code I am trying to compile:

#include <stdint.h>
#include <stdbool.h>
#include "utils/ustdlib.h"
#include "inc/hw_types.h"
#include "inc/hw_memmap.h"
#include "driverlib/sysctl.h"
#include "driverlib/pin_map.h"
#include "driverlib/debug.h"
#include "driverlib/hibernate.h"
#include "driverlib/gpio.h"

int main(void)
{
    SysCtlClockSet(SYSCTL_SYSDIV_5|SYSCTL_USE_PLL|SYSCTL_XTAL_16MHZ|SYSCTL_OSC_MAIN);

    SysCtlPeripheralEnable(SYSCTL_PERIPH_GPIOF);
    GPIOPinTypeGPIOOutput(GPIO_PORTF_BASE, GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3);
    GPIOPinWrite(GPIO_PORTF_BASE,GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, 0x08);

    SysCtlPeripheralEnable(SYSCTL_PERIPH_HIBERNATE);
    HibernateEnableExpClk(SysCtlClockGet());
    HibernateGPIORetentionEnable();
    SysCtlDelay(64000000);
    HibernateWakeSet(HIBERNATE_WAKE_PIN);
    GPIOPinWrite(GPIO_PORTF_BASE,GPIO_PIN_3, 0x00);

    HibernateRequest();
    while(1)
    {
    }
}

and I get this error:

Any ideas/help greatly appreciated,
