5 ART-PI Smart User 运行LED 程序崩溃

使用的master分支下的代码，通过 6ull bootloader 中的tftp获取kernel后能正常运行，并挂载emmc,和sd卡。

在userapps中添加led_test.c，代码如下：

```c
#include "led_test.h"

#define LED_PIN  GET_PIN(1,3)

int main()
{
    rt_device_t pin_dev;
    struct rt_device_pin_mode pin_mode;
    struct rt_device_pin_status pin_status;

pin_dev = rt_device_find("pin");
    if (pin_dev == RT_NULL)
    {
        rt_kprintf("not find pin device!\n");
        return -1;
    }
    rt_device_open(pin_dev, RT_DEVICE_OFLAG_RDWR);
    pin_mode.pin = LED_PIN;
    pin_mode.mode = 0;

rt_device_control(pin_dev, 0 ,(void*)&pin_mode);
    pin_status.pin = LED_PIN;

while(1)
    {
        pin_status.status = 0;
        rt_device_write(pin_dev, 0 ,(void*)&pin_status, sizeof(pin_status));
        rt_thread_mdelay(200);
        pin_status.status = 1;
        rt_device_write(pin_dev, 0 ,(void*)&pin_status, sizeof(pin_status));
        rt_thread_mdelay(200);
    }
    rt_device_close(pin_dev);
    return 0;
}

```
将Userapps 下的hello 和 led 编译后放到sd卡中，kernel运行后运行hello正常，但是运行led，程序直接崩溃了。

```c
msh /sd0>./hello
msh /sd0>hello world! test
msh /sd0>./led
msh /sd0>Function[rt_aspace_fault_try_fix]: scheduler is not available

怀疑是led测试程序的问题，然后将这部分功能直接放到kernel中，通过msh来调用，是可以正常运行的。
看了下运行报错的地方，没太搞懂是为啥出现了这个情况， 有大佬能解答一下么
