图2是根据另一示例性实施例示出的一种固件刷新方法的方法流程图，该固件刷新方法可以适用于电子设备中，包括如下步骤。
在步骤201中，在电子设备处于启动阶段时，检测在启动阶段之前与电子设备相连的接入设备是否为免驱设备。
电子设备未启动时，接入设备通过电子设备提供的外部接口与电子设备相连，该外部接口可以是电子设备上的USB(Universal Serial Bus，通用串行总线)接口。当电子设备上没有提供USB接口时，电子设备也可以通过专用连接线与接入设备进行连接。比如，智能手机一类的电子设备中没有提供USB接口，智能手机可以通过专用连接线与接入设备进行连接。
电子设备与接入设备相连后，启动该电子设备。在启动阶段，电子设备会检测是否连接了接入设备，当检测到连接了接入设备时，电子设备会对该接入设备是否是免驱设备进行检测，免驱设备是指不需要特定的驱动程序即可运行的设备。其中，电子设备检测接入设备是否是免驱设备可以包括如下子步骤：
一、电子设备获取在启动阶段之前与电子设备相连的接入设备的接口描述符信息。
接入设备的接口描述符信息用于标识接入设备的功能，电子设备通过获取该接口描述符信息来确定需要加载何种驱动程序来驱动该接入设备。该接口描述符信息包含接口的基类类型、接口的子类类型和接口协议，电子设备通过接口枚举，分别获取该接口描述符信息中的接口的基类类型、接口的子类类型和接口协议信息。比如，电子设备通过接口枚举，获取到该接入设备的接口的基类类型为USB_CLASS_MASS_STORAGE，接口的子类类型为USB_SCSI，接口协议为USB_PR_BULK。
二、当接口描述符信息指示接入设备为大容量存储设备时，电子设备获取接入设备的设备类型信息。
电子设备对接口枚举过程中获取到的接口描述符信息进行识别，当该接口描述符信息 指示该接入设备为大容量存储设备时，电子设备将进一步获取该接入设备的设备类型信息，该设备类型信息可以由电子设备发送SCSI(Small Computer System Interface，小型计算机系统接口)获取指令获得。
比如，电子设备获取到接入设备的接口描述符信息为接口的基类类型为USB_CLASS_MASS_STORAGE，接口的子类类型为USB_SCSI，接口协议为USB_PR_BULK，即可确定该接入设备为大容量存储设备，电子设备发送SCSI获取指令，并将获取到的返回值确定为该设备的设备类型信息。
三、当设备类型信息指示接入设备的设备类型为免驱类型时，电子设备确定接入设备为免驱设备。
其中，可以预先设置返回值与设备类型的对应关系。比如，电子设备发送SCSI获取指令后，收到的返回值为0x00，根据该返回值和对应关系，电子设备可以确定该接入设备为U盘，属于免驱类型，即可确定该接入设备为免驱设备。
在步骤202中，从接入设备中获取更新固件的存储地址。
由于确定了该接入设备为免驱设备，电子设备不需要使用特定的驱动即可读取该接入设备中存储的更新固件。在读取更新固件时，由于接入设备采用的文件系统类型的不同，对应的更新固件的存储地址也不相同，所以电子设备需要根据接入设备的文件系统类型确定该更新固件的存储地址。该步骤可以包括如下子步骤：
一、电子设备读取接入设备的特定扇区中的信息。
不同的文件系统对应的特定扇区中的信息的存储格式不同，所以电子设备可以通过读取接入设备的特定扇区中的信息来确定接入设备的文件系统。需要说明的是，电子设备通常读取接入设备的第一个扇区中的信息。
二、电子设备根据特定扇区中的信息判断接入设备是否采用了特定文件系统。
在电子设备根据读取到的特定扇区中的信息确定接入设备采用的文件系统类型时，该电子设备中预先存储有特定扇区中的信息与文件系统类型的对应关系表，电子设备根据读取到的特定扇区中的信息查找对应的文件系统类型，当能够查找到对应的文件系统类型时，即可确定该接入设备采用了特定文件系统。其中，特定扇区中的信息与文件系统类型的对应关系表的表结构可以如表一所示：
表一
特定扇区中的信息 文件系统
A格式存储的信息 A文件系统
B格式存储的信息 B文件系统
C格式存储的信息 C文件系统
三、若判断出接入设备采用了特定文件系统，电子设备则将预定存储地址确定为更新固件的存储地址。
电子设备在根据特定扇区中的信息确定文件系统之后，可以根据该文件系统确定更新 固件的存储地址。其中，文件系统与更新固件的存储地址的对应关系可以如表二所示：
表二
文件系统 更新固件的存储地址
A文件系统 存储地址A
B文件系统 存储地址B
C文件系统 存储地址C
其中，该预定存储地址可以是接入设备中的一条存储路径。比如，该预定存储地址可以为“H：\固件”，表示更新固件的存储地址为H盘根目录下的固件文件夹。
不同文件系统对应的更新固件的存储地址可以相同也可以不同，本实施例仅以不同文件系统对应的更新固件的存储地址不同进行举例说明，并不对本发明构成限定。
四、若判断出接入设备未采用特定文件系统，电子设备则根据特定扇区中的信息携带的元信息确定更新固件的存储地址，该元信息包括更新固件的起始地址和数据长度。
当电子设备未能从特定扇区中的信息与文件系统类型的对应关系表中查找到与读取到的特定扇区中的信息对应的文件系统时，电子设备确定该接入设备未采用特定文件系统。电子设备可以根据该特定扇区中的信息包含的元信息，获取该元信息中包含的更新固件的起始地址和数据长度，确定更新固件的存储地址。
在步骤203中，确定电子设备中的固件存储区域。
由于电子设备中固件存储区域的信息存储在内部闪存的元信息中，所以电子设备可以读取内部闪存的元信息，确定存放更新固件的固件存储地址。其中，固件存储区域用于存储固件。
当电子设备中存在一个固件存储区域时，该固件存储区域用于存储电子设备处于正常运行阶段时运行的固件；当电子设备中存在至少两个固件存储区域时，其中一个固件存储区域被置为活跃区，该置为活跃区的固件存储区域用于存储电子设备处于正常运行阶段时运行的固件，其余的固件存储区域均被置为非活跃区，该置为非活跃区的固件存储区域用于存储电子设备不运行的固件。
电子设备可以读取内部闪存的元信息，将电子设备中仅存的一个固件存储区域确定为存储更新固件的固件存储区域，或，将电子设备中置为非活跃区的固件存储区域确定为存储更新固件的固件存储区域。
步骤202与步骤203没有严格的先后关系，本实施例仅以步骤202在步骤203之前执行进行说明，并不对本发明构成限定。
在步骤204中，将存储地址中存储的更新固件写入固件存储区域中。
由于将更新固件写入不同的固件存储区域中的方式不同，因此，本实施例分别以上述确定的两种固件存储区域为例，对更新固件的写入流程进行说明。
第一，当电子设备中仅存在一个固件存储区域时，电子设备将更新固件替换固件存储区域中存储的原始固件。
当电子设备中仅存在一个固件存储区域时，电子设备读取接入设备中的更新固件，并将该更新固件写入固件存储区域存储，替换该固件存储区域存储的原始固件。
可选的，为了保证更新固件的准确性，电子设备还需要检测更新固件是否被正确写入固件存储区域。电子设备会根据存储在预定位置的校验值对该更新固件是否被正确写入进行检测，该校验值可以存储在该更新固件的头部或者尾部。比如，电子设备从更新固件的头部获取该校验值，并使用该校验值对写入的更新固件做CRC(Cyclic Redundancy Check，循环冗余校验码)校验，根据校验结果确定更新固件是否被正确写入固件存储区域。
在将接入设备中的更新固件写入固件存储区域后，电子设备会发出提示信息，该提示信息用于提醒用户更新固件写入完毕，提示用户断开接入设备，并重新启动电子设备，其中该提示信息可以是语音或文字信息。
第二，当电子设备中存在至少两个固件存储区域时，电子设备将更新固件写入其中置为非活跃区的固件存储区域中，该置为非活跃区的固件存储区域用于存储电子设备不运行的固件。
比如，电子设备中有两个固件存储区域，其中一个是置为活跃区的固件存储区域，另一个是置为非活跃区的固件存储区域，电子设备将接入设备中存储的更新固件写入该置为非活跃区的固件存储区域中。
可选的，本实施例提供的固件更新方法还包括：
1)检测更新固件是否被正确写入置为非活跃区的固件存储区域中；
2)若检测出更新固件已经被正确写入置为非活跃区的固件存储区域中，则将原来置为活跃区的固件存储区域置为非活跃区，将正确写入更新固件的固件存储区域置为活跃区，该置为活跃区的固件存储区域用于存储电子设备处于正常运行阶段时运行的固件。
其中，为了保证更新固件的准确性，电子设备会根据存储在预定位置的校验值对该更新固件是否被正确写入进行检测，该校验值可以存储在该更新固件的头部或者尾部。比如，电子设备从更新固件的头部获取该校验值，并使用该校验值对写入的更新固件做CRC校验，根据校验结果确定更新固件是否被正确写入固件存储区域。
当检测到该更新固件被正确写入时，电子设备确定能够正确运行该更新固件，电子设备将该非活跃区置为活跃区。为了保证电子设备中仅存在一个活跃区，电子设备还需要将原先的活跃区置为非活跃区。在设置完毕后，电子设备会发出提示信息，该提示信息用于提醒用户更新固件写入完毕，提示用户断开接入设备，并重新启动电子设备
电子设备可以保留非活跃区中的固件，也可以将该固件进行删除或替换，本发明并不对此进行限定。
在步骤205中，在电子设备处于重启之后的正常运行阶段时，运行写入电子设备中的更新固件。
电子设备处于启动阶段时，将会检测是否有接入设备与该电子设备相连，当未检测到有接入设备与该电子设备相连时，电子设备进入正常运行阶段，将运行写入固件存储区域 的更新固件，从而实现固件的更新；当检测到有接入设备与该电子设备相连时，电子设备将执行步骤201至步骤204。
综上所述，本实施例提供的固件刷新方法，通过在电子设备处于启动阶段时，检测在启动阶段之前与电子设备相连的接入设备是否为免驱设备；若检测出接入设备为免驱设备，则将接入设备中的更新固件写入电子设备中；在电子设备处于重启之后的正常运行阶段时，运行写入电子设备中的更新固件；使得电子设备中未安装相应驱动时，也可以通过免驱设备完成电子设备的固件刷新，解决了当电子设备中未安装相应的驱动程序时，将不能读取专业刷机工具中的固件，导致固件刷新失败的问题；达到了简化固件刷新过程，提高固件刷新成功率的效果。
另外，通过电子设备对接入设备是否采用特定文件系统进行检测，当采用了特定文件系统时从预定存储位置获取更新固件，当未采用特定文件系统时，根据特定扇区中的信息携带的元信息获取更新固件，使得电子设备可以从不同的文件系统中读取更新固件，提高了固件刷新的成功率，扩大了固件刷新的使用范围。
另外，通过检测更新固件是否被正确写入置为非活跃区的固件存储区域中；若检测出更新固件已经被正确写入置为非活跃区的固件存储区域中，则将该固件存储区域置为活跃区，在检测到更新固件被正确写入时将该非活跃区设置为活跃区，保证了写入的更新固件的正常运行。
