Freertos RM57Lx LaunchPad multiple tasks only execute once

I trying out the FreeRTOS port on my http://www.ti.com/tool/launchxl2-rm57l board and I've run into a strange issue. I have two tasks (one toggles the led, the other writes to the serial port). Either task will run if it is the only task but if I create both they will only run once and never return from the call to vTaskDelay.

void writeToSci(void * pvParameters)
{
    while (1)
    {
    	sciDisplayText(sciREGx, txtCRLF, sizeof(txtCRLF));
    	sciDisplayText(sciREGx, txtTitle, sizeof(txtTitle));
    	sciDisplayText(sciREGx, txtCRLF, sizeof(txtCRLF));
    	vTaskDelay(500);
	}

}

void flashLed(void * pvParameters)
{
    while (1)
    {
        gioToggleBit(gioPORTB, 6);
		vTaskDelay(500);
	}
}

It must but something I've configured incorrectly or maybe a licensing issue?
