非 OS SDK 其实相当于单线程，您使用的 os_delay_us 其实是 while 住了系统，影响底层喂看门狗，因而看门狗复位了。

结果是不断重启。

Code:

#define DELAY 1000 /* milliseconds */

LOCAL os_timer_t hello_timer;
extern int ets_uart_printf(const char *fmt, ...);

LOCAL void ICACHE_FLASH_ATTR hello_cb(void *arg)
{
   ets_uart_printf("Hello World!\r\n");
}

static void ICACHE_FLASH_ATTR systemInitDoneHandler() {
   os_delay_us(5*1000000);
}

void user_init(void)
{
   // Configure the UART
   uart_init(BIT_RATE_115200, BIT_RATE_115200);

   os_timer_disarm(&hello_timer);
   os_timer_setfn(&hello_timer, (os_timer_func_t *)hello_cb, (void *)0);
   os_timer_arm(&hello_timer, DELAY, 1);

   system_init_done_cb(systemInitDoneHandler);
}
