CCS/TM4C1294NCPDT: Rebooting issue when using SYS/BIOS and CanOpen

Tool/software: Code Composer Studio

Hi 

I am encountering the TM4C infinite self reboots problem. My main() looks like the below :

I created another task which is started in Application_Init() and turns off the LED_HEARTBEAT.

The board will oscillate the LED when powered on and this looks like an infinite reboot situation. 

I looked around in the code but don't find any watchdog codes so doubt that it is due to watchdog.

int main(void)
{
board_variant_t board_variant;

// Call board init functions
board_variant = Board_init();

if (board_variant != BOARD_VARIANT_INIT)

{
// Initialise the Serial Debug module
SerialDebug_Init();
}

// Initialise the Non-Volatile Memory Data Manager
NvmMgr_Init(board_variant);

// Initialise the CANopen stack
CANopen_Init();

// Initialise the Enumeration Task
Enumeration_Init(board_variant);

// Initialise the Application
Application_Init(board_variant);

GPIO_write(LED_HEARTBEAT, LED_ON);

// enable CPU interrupt
MAP_IntMasterEnable();

System_flush();

// Start BIOS
BIOS_start();

return (0);
}
