[s:154] 如题，已成功跑起点灯应用（移植自stm3210例程）：
```
char thread_led1_stack[1024];
struct rt_thread thread_led1;
static void rt_thread_entry_led1(void* parameter)
{
    while (1)
    {
        /* led on */
        rt_kprintf("led1 on
");
        gpio_tgl_gpio_pin(AVR32_PIN_PA08);
        rt_thread_delay(50); /* sleep 0.5 second and switch to other thread */

/* led off */
        rt_kprintf("led1 off
");
        gpio_tgl_gpio_pin(AVR32_PIN_PA08);
        rt_thread_delay(50);
    }
}

char thread_led2_stack[1024];
struct rt_thread thread_led2;
void rt_thread_entry_led2(void* parameter)
{
    unsigned int count=0;
    while (1)
    {
        /* led on */
        rt_kprintf("led2 on,count : %d
",count);
        count++;
        gpio_tgl_gpio_pin(AVR32_PIN_PA07);
        rt_thread_delay(RT_TICK_PER_SECOND);

/* led off */
        rt_kprintf("led2 off
");
        gpio_tgl_gpio_pin(AVR32_PIN_PA07);
        rt_thread_delay(RT_TICK_PER_SECOND);
    }
}

int rt_application_init()
{
    /* create led1 thread */
    rt_thread_init(&thread_led1,
                   "led1",
                   rt_thread_entry_led1,
                   RT_NULL,
                   &thread_led1_stack[0],
                   sizeof(thread_led1_stack), 5, 5);
    rt_thread_startup(&thread_led1);

//------- init led2 thread
    rt_thread_init(&thread_led2,
                   "led2",
                   rt_thread_entry_led2,
                   RT_NULL,
                   &thread_led2_stack[0],
                   sizeof(thread_led2_stack),10,10);
    rt_thread_startup(&thread_led2);

return 0;
}
```

正在写更深入测试的代码，例如中断抢占等压力测试。
