为什么activate_retry_interval的值不等于3？

各位高手，小弟正在基于庆科micokit-3165开发板和MICO操作系统开发应用。正在调试micokit_enjoy工程。运行完成“uint32_t activate_retry_interval = 3;”后，查看activate_retry_interval的值为2779096485,请教activate_retry_interval的值为什么不等于3？谢谢！部分代码如下：
    void fogcloud_main_thread(void *arg)
{
  OSStatus err = kUnknownErr;
  app_context_t* inContext = (app_context_t *)arg;
  
  MVDResetRequestData_t devResetRequestData;
  
#ifdef ENABLE_FOGCLOUD_AUTO_ACTIVATE
  MVDActivateRequestData_t devDefaultActivateData;
  uint32_t activate_retry_interval = 3;
#endif
  
  activate_retry_interval = 3;
  
  /* wait for station on */
  while(!inContext->appStatus.isWifiConnected){
    mico_thread_msleep(500);
  }
  
  //--- create msg recv queue, NOTE: just push msg pionter into queue, so msg memory must be freed after used.
  if(NULL == msg_recv_queue_mutex){
    err = mico_rtos_init_mutex(&msg_recv_queue_mutex);
require_noerr_action(err, exit,fogcloud_log("ERROR: mico_rtos_init_mutex
(msg_recv_queue_mutex) failed, err=%d.", err));
  }
