使用了官方例程的RT-Thread工程，在新增led_blink任务时遇到问题；
#include "led.h"
#include
#include
struct rt_thread led_blink_thread;
static char uart_ble_tx_stack[256] = {0};
static void led_blink_entry(void* paramenter)
{
rt_pin_mode(LED_G, PIN_MODE_OUTPUT);
rt_kprintf("led_blink_entry startup.\r\n");
while(1){
rt_pin_write(LED_G, PIN_LOW);
rt_thread_mdelay(500);
rt_pin_write(LED_G, PIN_HIGH);
rt_thread_mdelay(500);
}
}
int led_blink_init(void)
{
rt_kprintf("led_blink_init enter.\r\n");
rt_thread_init(&led_blink_thread,"led",led_blink_entry,RT_NULL,&uart_ble_tx_stack[0],
sizeof(uart_ble_tx_stack),THREAD_PRIORITY - 1, THREAD_TIMESLICE);
rt_thread_startup(&led_blink_thread);
return 0;
}
主程序调用led_blink_init后，对应的led并没有闪烁，使用list_thread命令可以查看到led任务已创建。
msh >list_thread

请问出现这种问题的原因是什么？
另外还想问一下为什么main的状态是suspend？
