这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
图1是根据一示例性实施例示出的对固件进行升级的方法的流程图，该对固件进行升级的方法可以应用在智能设备(例如：智能插座、智能电视、智能空调等)上，如图1所示，该对固件进行升级的方法包括以下步骤S101至S103：
在步骤S101中，在确定第一芯片的固件需要升级时，识别第二芯片的闪存中的用于下载第二芯片的固件的第一分区。
在一实施例中，可以通过远程控制的方式确定第一芯片的固件需要升级，也可以在智能设备上以触发按键的方式确定第一芯片的固件需要升级。在一实施例中，例如，第一芯片为蓝牙芯片、WIFI芯片等非MCU芯片，第二芯片可以为MCU芯片或者类MCU芯片，第一分区可以为MCU芯片中的闪存中的备份区，可替换地，第一芯片可以为MCU芯片，第二芯片为蓝牙芯片、WIFI芯片等非MCU芯片，本公开实施例不对第一芯片与第二芯片 的具体名称进行限制，第一芯片与第二芯片中有一个芯片设置有闪存即可。
在步骤S102中，将第一芯片的新的固件下载到第一分区。
在一实施例中，可以通过互联网络将第一芯片的固件下载到第一分区。
在步骤S103中，将第一芯片的新的固件从第一分区拷贝到第一芯片中的有效区域。
在一实施例中，第一芯片的有效区域可以根据固件的类型来确定。
在本实施例中，通过先确定第一芯片的固件需要升级，避免同时对多个芯片的固件进行升级时出现的冲突，提高了芯片在固件升级时的安全性；通过将第一芯片的新的固件下载到第二芯片的闪存中的第一分区，经第一芯片的新的固件从第一分区拷贝到第一芯片中的有效位置，实现了借助第二芯片的闪存对第一芯片的新的固件进行升级，在升级过程中避免了采用额外的控制逻辑，节约了智能设备的资源。
在一实施例中，对固件进行升级的方法还可以包括：
在确定第二芯片的固件需要升级时，将第二芯片的新的固件下载到第一分区；
将第一分区激活成用于存储第二芯片的原有固件的第二分区；
将第二分区设置为用于下载第二芯片的固件的第一分区。
在一实施例中，步骤S101还可以包括：
获取第二芯片的分区信息；
通过分区信息识别第二芯片的闪存中的用于下载第二芯片的固件的第一分区。
在一实施例中，对固件进行升级的方法还可以包括：

具体如何对智能设备上的固件进行升级的，请参考后续实施例。
至此，本公开实施例提供的上述方法，可以避免同时对多个芯片的固件进行升级时出现的冲突，提高了芯片的固件升级时的安全性，在升级过程中还可以避免采用额外的控制逻辑，节约了智能设备的资源。
下面以具体实施例来说明本公开实施例提供的技术方案。
图2是根据一示例性实施例一示出的对固件进行升级的方法的流程图；本实施例利用本公开实施例提供的上述方法，以第二芯片为MCU芯片，并通过对MCU芯片中的固件进行升级为例进行示例性说明，如图2所示，包括如下步骤：
在步骤S201中，在确定第二芯片的固件需要升级时，获取第二芯片的分区信息。
在一实施例中，与上述步骤S101中的描述相似，可以通过远程控制的方式确定需要升级的固件为MCU芯片，也可以在智能设备上以触发按键的方式确定需要升级的固件为MCU芯片。第二芯片的分区信息表明了闪存中的第一分区与第二分区所在的区域。
在步骤S202中，通过分区信息识别第二芯片的闪存中的用于下载第二芯片的固件的第一分区。
在一实施例中，第一分区例如为闪存的备份区。
在步骤S203中，在第一芯片的新的固件下载到第一分区后，对第一芯片的新的固件 进行校验。
在一实施例中，可以通过循环冗余校验码(Cyclic Redundancy Check，简称为CRC)对第一芯片的新的固件进行校验，也可以通过新的固件的格式信息对新的固件进行校验，通过对第一芯片的新的固件进行校验，可以确保新的固件是正常的，从而确保固件升级的可靠性。
在步骤S204中，将第二芯片的新的固件下载到第一分区。
在步骤S205中，将第一分区激活成用于存储第二芯片的原有固件的第二分区。
在一实施例中，第二分区例如为闪存的活跃区，该活跃区用于存储MCU芯片的原有固件。
在步骤S206中，将第二分区设置为用于下载第二芯片的固件的第一分区。
本实施例中，以第二芯片为MCU芯片为例进行示例性说明，通过将MCU芯片需要升级的固件下载到备份区，将备份区设置为活跃区，并将原有固件所在的第二分区设置为备份区，实现了在不占用智能设备的其它资源的基础上对MCU芯片的固件进行了升级，避免了采用额外的控制逻辑，节约了智能设备的资源。
图3是根据一示例性实施例二示出的对固件进行升级的方法的流程图；本实施例利用本公开实施例提供的上述方法，以先对智能设备上的MCU芯片中的固件进行升级，然后再对非MCU芯片(例如，WIFI芯片、蓝牙芯片等等)中的固件进行升级为例进行示例性说明，如图3所示，包括如下步骤：
在步骤S301中，在确定第二芯片的固件需要升级时，获取第二芯片的分区信息。
在一实施例中，与上述步骤S101中的描述相似，可以通过远程控制的方式确定MCU芯片的固件需要升级，也可以在智能设备上以触发按键的方式确定MCU芯片的固件需要升级。第二芯片的分区信息表明了闪存中的第一分区与第二分区所在的区域。
在步骤S302中，通过分区信息识别第二芯片的闪存中的用于下载第二芯片的固件的第一分区。
在步骤S303中，将第二芯片的新的固件下载到第一分区。
在步骤S304中，在第二芯片的新的固件下载到第一分区后，对第二芯片的新的固件进行校验。
在步骤S305中，将第一分区激活成用于存储第二芯片的原有固件的第二分区。
在步骤S306中，将第二分区设置为用于下载第二芯片的固件的第一分区。
上述步骤S301至步骤S306的描述，可以参见上述步骤S201至步骤S206的描述，在此不再详述。
步骤S307，在确定需要升级的固件为第一芯片时，将第一芯片的新的固件下载到第一分区。
在一实施例中，例如，第一芯片为WIFI芯片，MCU的闪存中的第一分区为闪存中原来的第二分区，该第一分区经过步骤S305设置后成备份区。
在步骤S308中，将第一芯片的新的固件从第一分区拷贝到第一芯片中的有效区域。
本实施例中，以对第一芯片中的固件与第二芯片中的固件进行升级为例进行示例性说明，通过将MCU需要升级的固件下载到备份区，将备份区设置为活跃区，并将原有固件所在的第二分区设置为备份区，然后将WIFI芯片需要升级的固件下载到备份区，再将WIFI芯片需要升价的固件拷贝到WIFI芯片中的有效区域，避免同时对MCU芯片的固件与WIFI芯片的固件进行升级时出现的冲突，提高了MCU芯片与WIFI芯片的固件升级时的安全性；通过将WIFI芯片的新的固件下载到MCU芯片的闪存中的第一分区，经WIFI芯片的新的固件从备份区拷贝到WIFI芯片中的有效位置，实现了借助MCU芯片的闪存对WIFI芯片的新的固件进行升级，在升级过程中避免了采用额外的控制逻辑，节约了智能设备的资源。可替换地，WIFI芯片还可以为蓝牙芯片，对蓝牙芯片中的固件进行升级的过程可以参考上述描述，在此不再详述。
下面通过图4A至图4E对本公开实施例的固件升级过程进行示例性说明，本公开实施例以第一芯片为WIFI芯片，第二芯片为MCU芯片为例进行示例性说明，本领域技术人员可以理解的是，对于智能设备中存在闪存的芯片，通过闪存中的不同分区对其它需要升级的固件进行升级的技术方案，均可以理解为本公开实施例的技术方案。
当两个或两个以上的芯片的固件均需要进行升级时，可以根据智能设备接收到的指令的先后顺序，按照上述对固件进行升级的方法对智能设备中的多个固件升级。举例如下：
如图4A所示，当智能设备40中包括MCU芯片41和WIFI芯片42，其中，MCU芯片41中的闪存包括第一分区411与第二分区412，第一分区411用于下载MCU芯片41的固件，第二分区412用于存储MCU芯片的原有固件，更形象的表述，第一分区411可以称为MCU芯片的闪存中的备份区，第二分区412可以称为MCU芯片的闪存中的活跃区。
在一实施例中，MCU芯片41和WIFI芯片42均需要进行固件升级。如图4B所示，智能设备可以通过远程下载的方式将MCU芯片41的新的固件下载到第一分区411中。如图4C所示，可以对MCU芯片41的新的固件进行校验，从而确保MCU芯片41的新的固件无问题后将MCU芯片41的新的固件的所在区域第二分区412激活为活跃区，将MCU芯片41原有的固件所在的区设置为第一分区(也即备份区)。
如图4D所示，智能设备通过远程下载的方式将WIFI芯片42的新的固件下载到MCU芯片的第一分区。如图4E所示，在对WIFI芯片42的新的固件校验完毕后，将WIFI芯片42的新的固件拷贝到WIFI芯片中，并覆盖WIFI42的原有固件，重新启动智能设备，即可完成智能设备的固件升级。
通过上述过程的描述，可以很清楚地理解本公开实施例对固件进行升级的过程，本领域技术人员可以理解的是，上述过程仅为一个示例性说明并不能形成对本公开实施例的限制。
