1.hbot在归零的时候卡死了，阻塞在了第四步，猜测可能原因是由于下面代码导致的
```c
int32_t XYRobotCtrlModule::waiting_for_stop(function<bool()> condition_fn, bool checkWhenLoop, int32_t delay) {
  while (!_motor_is_reach_target()) {
    if (m_thread.getExitFlag()) break;
    if (condition_fn()) break;
    if (checkWhenLoop && !check_when_run()) {
      break;
    }
    osDelay(delay);
  }
  _motor_stop(); //可能原因这里发送SPI指令失败导致的。
  while (_motor_is_reach_target()) { //可能阻塞在这一行
    osDelay(10);
  }
  return 0;
}
```
