下面是代码，最下面的注释是报错原因
```c
#include <rtthread.h>

#define DBG_TAG "main"
#define DBG_LVL DBG_LOG
#include <rtdbg.h>

rt_thread_t th1_ptr = NULL;         //数据类型为地址类型，定义结构体用以接受线程1的返回值,初始化为空
struct rt_thread th2;               //定义线程结构体th2，用于创建静态线程

rt_uint8_t th2_stack[512] = {0};                         //定义数组(连续)，无符号八位，即为一个字节

void th1_entry(void *parameter)      //定义线程的处理函数
{
    unsigned int i = 0;
    for(i = 0;i < 5; i++){
            rt_kprintf("th1_entry running...\n");
            rt_thread_mdelay(1000);
}
void th2_entry(void *parament){

unsigned int i = 0;
    for(i = 0;i < 10; i++){
        rt_kprintf("th2_entry running...\n");
        rt_thread_mdelay(1000);
    }

}

void scheduler_hook(struct rt_thread *from, struct rt_thread *to)
{
    //打印线程从哪到哪的关系
    rt_kprintf("from:%s ---> to:%s\n",from->name,to->name);

}

int main(void)
{
    int ret = 0;

rt_scheduler_sethook(scheduler_hook);

//创建动态线程1
    th1_ptr = rt_thread_create("th1_demo",th1_entry,NULL,1024,20,5);
    if(th1_ptr == RT_NULL)      //创建失败
    {
        //打印失败信息
        LOG_E("rt_thread_creat faild...\n");
        return -RT_ENOMEM;
    }
    LOG_D("rt_thread_creat successed...\n");
    rt_thread_startup(th1_ptr);

//创建静态线程2
    ret = rt_thread_init(&th2,"th2_demo",th2_entry,NULL,th2_stack,sizeof(th2_stack),19,5);
    if(ret < 0)
    {
        //打印失败信息
        LOG_E("rt_thread_int faild...\n");
        return ret;
    }
    LOG_D("rt_thread_init successed...\n");
    rt_thread_startup(&th2);

return RT_EOK;

}
```
