FRDM-K64F crashes trying to set SPI ports

[roel0]

int main()  {      volatile uint32_t i;       // Init clocks      hardware_init();      dbg_uart_init();      OSA_Init();      GPIO_DRV_Init(switchPins, ledPins);                LED1_EN;       LED1_TOGGLE;      configure_spi_pins(SPI1_IDX);

The code above crashes on line 14

GDB output:

This is my first project on this board an I've absolute no idea what the cause is of this error. Has anyone had familiar errors?
Thanks in advance!

The problem was I was using an old example which was missing the following line in hardware_init.c

CLOCK_SYS_EnablePortClock(PORTD_IDX);
