taskYield() hangs – help needed!

Hi, I’m trying to make my application work and I encounter issues like this one. First, I’m using FreeRTOS on a AVR32 UC3 chip. I use the Atmel framwork 1.4. I currenty have 3 task running. The main one, a startup one, the main LWIP one. I goes like this: main.cpp {

    // Start the Startup Task. Done this way to start the scheduler as soon as possible!
    // The reason is simple… The scheduler enables the interrupts (used by the serial communication).
    xTaskCreate(StartupTask, (const signed portCHAR*) "STARTUP_TASK", TASK_STARTUP_STACK_SIZE, (void*)pRadarUnit, TASK_STARTUP_PRIORITY, NULL);     // Start the OS scheduler. It should never return from there.
    vTaskStartScheduler();     return 0;
} So, my main task is starting a STARTUP task that will create and initialize all modules. At this point, my LWIP task is already started. Then, my startup task will try to create another task. The problem I have is that inside signed portBASE_TYPE xTaskCreate( pdTASK_CODE pvTaskCode, const signed portCHAR * const pcName, unsigned portSHORT usStackDepth, void *pvParameters, unsigned portBASE_TYPE uxPriority, xTaskHandle *pxCreatedTask ) the application hangs on taskYIELD(); My RTOS is configured in preemtive mode. Not sure what to do next… If anyone can help me…
Thanks

Could you attempt to post the code again?  I need to work out how it is supposed to work, sometimes it seems to format correctly automatically, and other times not.  I suppose I should RTFM. Regards.

There you go: // Start the Startup Task. Done this way to start the scheduler as soon as possible!
    // The reason is simple… The scheduler enables the interrupts (used by the serial communication).
    xTaskCreate(StartupTask, (const signed portCHAR*) "STARTUP_TASK", TASK_STARTUP_STACK_SIZE, (void*)pUnit, TASK_STARTUP_PRIORITY, NULL);     // Start the OS scheduler. It should never return from there.
    vTaskStartScheduler();     return 0;
