本公开示例性实施方式首先提供一种固件升级方法，用于电子设备，电子设备包括无线充电芯片，图1为本公开实施例提供的一种固件升级方法的流程图，如图1所示，固件升级方法包括如下步骤：
步骤S110，判断第一固件和第二固件是否一致，第一固件为无线充电芯片内的固件，第二固件存储于电子设备的存储装置中；
步骤S130，当第一固件和第二固件不一致时，利用第二固件完成对无线充电芯片固件的升级。
本公开实施例提供的固件升级方法，通过判断无线充电芯片内的第一固件和电子设备的存储装置中的第二固件是否一致，当第一固件和第二固件不一致时，利用第二固件完成对无线充电芯片固件的升级，实现了对无线充电芯片固件的自动升级，进而保证无线充电功能的正常。
在实际应用中，无线充电芯片内的固件程序有可能会存在漏洞，为了修补漏洞或者为了提高无线充电的效率、降低功率损失、加快充电速度等，需要对无线充电的充电流程以及充电协议等进行更新，也即是需要对无线充电芯片中的第一固件进行升级。
其中，本公开实施例中所述的固件为充电芯片或者电子设备等设备的驱动程序，通过固件使操作系统能够充电芯片以及电子设备的驱动，使其按预设方式运行。通常固件被写入可擦写可编程只读存储器(EPROM)或电可擦可编程只读存储器(EEPROM)中。比如，第一固件可以是写入充电芯片内的驱动程序，用于驱动无线充电；电子设备的固件是写入电子设备的可擦写可编程只读存储器的驱动程序，用于驱动电子设备运行。
在步骤S110中，可以判断第一固件和第二固件是否一致，第一固件为无线充电芯片内的固件，第二固件存储于电子设备的存储装置中。
其中，第二固件可以是最新版本的无线充电芯片固件，第二固件存储于电子设备中，第二固件可以被编译于电子设备的固件中，或者第二固件可以单独存储于电子设备的存储装置中。可以在电子设备开机后进行第一固件和第二固件一致性的判断，在电子设备开机后进行第一固件和第二固件一致性的判断，然后进行固件升级，能够保证无线充电芯片的固件保持最新版本。或者在电子设备每工作预设时间间隔进行一次第一固件和第二固件一致性的判断。或者在触发指定事件后进行一次第一固件和第二固件一致性的判断。
在本公开一可行的实施方式中，如图2所示，步骤S110可以通过如下步骤实现：
步骤S210，获取第一固件的版本标识。
可以在电子设备开机，无线充电芯片的驱动模块完成初始化之后，通过应用处理器获取无线充电芯片中第一固件的版本标识，比如，第一固件的版本号。
示例的，当电子设备开机，无线充电芯片的驱动模块完成初始化之后，应用处理器向无线充电芯片发送第一固件版本查询命令，无线充电芯片响应该第一固件版本查询命令，向应用处理器发送当前无线充电芯片上的固件版本号。
在一种具体的实施方式中，可以是开机后应用处理器就向无线充电芯片发送第一固件版本查询命令，也即是每次开机应用处理器进行无线充电芯片固件版本查询。或者，在电子设备使用过程中，每间隔预设时间应用处理器向无线充电芯片发送第一固件版本查询命令。比如，每间隔24小时应用处理器向无线充电芯片发送第一固件版本查询命令。通过每间隔预设时间查询一次第一固件的版本，可以实现第一固件的自动更新，避免由于电子设备长期工作，而导致的第一固件不能及时更新。
可以理解的是，应用处理器也可以响应用户的手动操作而发送第一固件版本查询命令。比如，可以在电子设备上设置查询触发事件，当用户触发该查询触发事件后，应用处理器向无线充电芯片发送第一固件版本查询命令，无线充电芯片响应该第一固件版本查询命令发送第一固件的版本号至应用处理器。
在一种具体的实施方式中，无线充电芯片可以在初始化完成后，向应用处理器发送第一固件的版本号，应用处理器接收该第一固件的版本号。此后，无线充电芯片还可以每间隔预设时间向应用处理器发送第一固件的版本号。
步骤S230，获取第二固件的版本标识。
其中，第二固件可以是最新版本的无线充电芯片固件，第二固件被编译在电子设备的固件内，比如，第二固件可以以数组的形式编译在电子设备固件中。获取第二固件的本本标识可以是和获取第一固件的版本标识同时进行，或者先获取第一固件的版本标识再获取第二固件的版本标识，或者先获取第二固件的版本标识再获取第一固件的版本标识，本公开实施例对此不做具体限定。
电子设备的固件通常存储于电子设备的存储装置中，比如，电子设备的固件可以存储于随机存取存储器或者硬盘等存储装置中。可以通过应用处理器查询存储装置中的第二固件的版本号。
示例的，在获取第二固件的版本号时，可以是响应第一固件版本查询命令，查询第二固件的版本号，也即是同时获取第一固件和第二固件的版本号。或者，可以是响应第二固件版本查询命令进行第二固件版本号的查询，第二固件版本查询命令可以是早于第一固件查询命令或者晚于第一固件查询命令。
当第一固件版本的版本号是通过无线充电芯片主动发送给应用处理器时，可以在应用处理器接收到第一固件的版本号时，获取第二固件的版本号。
可以理解的是，第一固件和第二固件的版本标识可以是版本号，或者是设于第一固件和第二固件内的校验码等，本公开实施例并不以此为限。
步骤S250，判断第一固件的版本标识和第二固件的版本标识是否一致。
对比第一固件的版本标识和第二固件的版本标识，当第一固件的版本标识和第二固件的版本标识相同时，则判断第一固件和第二固件相同，也即是无线充电芯片中的第一固件是最新的固件，不需要进行固件升级。当第一固件的版本标识和第二固件的版本标识不一致时，则判断第一固件和第二固件不一致，无线充电芯片中的第一固件不是最新版本的固件，需要对第一固件进行升级。
在步骤S130中，当第一固件和第二固件不一致时，可以利用第二固件完成对无线充电芯片固件的升级。
其中，利用第二固件对无线充电芯片的固件升级，第二固件可以是完整的无线充电芯片的固件，此时可以是将第一固件擦除，并将第二固件写入。或者第二固件可以是无线充电芯片固件的升级包，其中包括了需要升级部分的无线充电芯片的固件，此时可以是将第二固件补充编译至第一固件。
在本公开一可行的实施方式中，如图3所示，步骤S130可以用过如下步骤实现：
步骤S310，将第三固件写入无线充电芯片的存储装置，第三固件为启动加载(BootLoader)固件。
其中，可以通过I2C将第三固件写入无线充电芯片的随机存取存储器中。当应用处理器判断第一固件的版本标识和第二固件的版本标识不同时，则第一固件需要进行升级。应用处理器发送固件升级指令，由于在非充电状态下无线充电芯片处于关断状态，此时首先需要启动无线芯片，通过启动加载固件实现无线充电芯片的初始化，以便于后续的固件升级。
I2C为数据通信总线，I2C总线包括数据线和时钟线，I2C总线可以用于无线充电芯片的数据传输。当然在实际应用中，也可以通过其他方式进行无线充电芯片的通信，本公开实施例并不以此为限。
第三固件可以存储于电子设备的存储装置中，当应用处理器发出固件升级指令后，第三固件从电子设备的存储装置中被发送至无线充电芯片。在无线充电芯片中，BootLoader是在芯片内核运行之前运行。可以初始化硬件设备、建立内存空间映射图，从而将芯片的软硬件环境带到一个合适状态，以便为最终调用芯片内核准备好正确的环境。
步骤S330，运行第三固件。
其中，将第三固件存储于无线充电芯片的存储装置之后，应用处理器控制第三固件在无线充电芯片上运行，初始化无线充电芯片的硬件设备、建立内存空间映射图，从而使芯片的软硬件环境进入合适的状态，实现无线充电芯片通过I2C总线和应用处理器的通信。
在本公开一可行的实施方式中，如图4所示，运行第三固件可以包括：
步骤S410，判断第三固件的启动状态是否正常。
其中，应用处理器在第三固件启动时，实时检测第三固件的启动状态，通过过第三固件的启动状态判断第三固件的启动状态是否正常。当第三固件的启动状态正常时，运行第三固件，然后执行步骤S350。
步骤S430，若第三固件的启动状态异常，则执行步骤：将第三固件写入无线充电芯片的存储装置。
当应用处理器判断第三固件的启动状态异常时，返回步骤S310，将第三固件重新写入无线充电芯片的存储装置，并运行第三固件。
进一步的，运行第三固件，还可以包括：
步骤S450，当第三固件连续启动状态异常次数大于第一预设阈值时，退出固件升级。
在运行第三固件时，可以记录第三固件启动状态异常的次数，当在一次固件升级中，第三固件的启动状态异常的次数超过第一预设阈值时，可以判断为固件升级故障，退出固件升级。比如，当在一次固件升级中，第三固件的启动状态异常的次数超过5次时，退出固件升级。无线充电芯片可以生成故障信息，将该故障信息发送至应用处理器。通过在第三固件的启动状态异常的次数超过第二预设阈值时退出固件升级，避免由于故障导致浪费固件升级时间，提高固件升级效率。
步骤S350，利用第三固件，将第二固件写入无线充电芯片。
其中，利用第三固件实现无线充电芯片和应用处理器的通信，应用处理器控制将第二固件写入无线充电芯片。当第二固件是完整的无线充电芯片的固件，此时可以是将第一固件擦除将第二固件写入。当第二固件是无线充电芯片固件的升级包，其中包括了需要升级部分的无线充电芯片的固件，此时可以是将第二固件补充至编译至第一固件。示例的，第二固件通过第三固件写入无线充电芯片的MTP(Media Transfer Protocol，媒体传输协议)。
在本公开一可行的实施方式中，如图5所示，利用第三固件，将第二固件写入无线充电芯片，可以包括如下步骤：
步骤S510，判断第二固件的写入是否正常。
其中，应用处理器在第二固件写入时，实时检测第二固件的写入状态，通过过第二固件的写入状态判断第三固件的写入状态是否正常。当第三固件的启动状态正常时，运行第二固件。
步骤S530，若第二固件的写入异常，则执行步骤：将第三固件写入无线充电芯片的存储装置。
当应用处理器判断第二固件的写入异常时，返回步骤S310，将第三固件重新写入无线充电芯片的存储装置，并运行第三固件。
进一步的，利用第三固件，将第二固件写入无线充电芯片，还包括：
步骤S550，当第二固件连续写入异常次数大于第二预设阈值时，退出固件升级。
在写入第二固件时，可以记录第二固件写入异常的次数，当在一次固件升级中，第二固件的写入异常的次数超过第二预设阈值时，可以判断为固件升级故障，退出固件升级。比如，当在一次固件升级中，第二固件的写入异常的次数超过5次时，退出固件升级。无线充电芯片可以生成故障信息，将该故障信息发送至应用处理器。通过在第二固件的写入异常的次数超过第二预设阈值时退出固件升级，避免由于故障导致浪费固件升级时间，提高固件升级效率。
值得注意的是，在实际应用中第一预设阈值和第二预设阈值可以相同，第一预设阈值和第二预设阈值也可以不同，本公开实施例对此不做具体限定。
进一步的，如图6所示，判断第一固件和第二固件是否一致之前，固件升级方法还包括：
步骤S150，获取第二固件，并将第二固件存储于电子设备的存储装置中。
其中，可以从服务器中获取第二固件，可以在电子设备开机联网后从服务器下载第二固件。或者在电子设备工作时，每间隔预设时间从服务器下载第二固件，比如每间隔24小时从服务器下载第二固件。或者可以在预设条件被触发下从服务器下载第二固件，比如，当电子设备连接WIFI时，从服务器下载第二固件。或者，在前一次第一固件更新后进行一次获取固件，然后在预设时间间隔获取第二固件。可以理解的是，第二固件也可以通过其他方式获取，比如从其他电子设备拷贝等，本公开实施例对此不做具体限定。
示例的，从服务器下载第二固件，可以是电子设备首先向服务器发送数据下载请求，服务器响应数据下载请求，向电子设备发送第二固件，终端接收第二固件并将第二固件以数组形式编译到电子设备的固件中。
在获取第二固件时，可以比较电子设备中的第二固件和服务器中的第二固件的版本标识。当服务器中的第二固件的版本标识和电子设备中的版本标识不同，并且服务器中的第二固件的版本新于电子设备中的第二固件的版本时，从服务器下载最新版本的第二固件，并替换电子设备中的第二固件。当电子设备中的第二固件和服务器中的第二固件的版本标识相同，则电子设备中的第二固件为最新版本的固件，此时不从服务器下载第二固件。
无线充电芯片在没有进行无线充电时，处于断电状态，应用处理器无法访问无线充电芯片，也即无法获取第一固件的版本标识，因此为了使应用处理器能够访问无线充电芯片，在判断第一固件和第二固件是否一致之前，如图7所示，固件升级方法还包括：
步骤S170，向无线充电芯片供电。
其中，当在电子设备开机对无线充电芯片进行固件升级时，可以在电子设备开机时向无线充电芯片供电；当在电子设备工作预设时间后对无线充电芯片进行固件升级时， 可以在应用处理器查询第一固件的版本标识之前向无线充电芯片供电。当无线充电芯片固件升级完成后，停止对无线充电芯片供电。
在本公开一可行的实施方式中，向无线充电芯片供电，可以包括：利用无线OTG(on-the-go)功能，向无线充电芯片供电。
其中，可以在电子设备开机后，开启无线OTG，利用无线OTG功能，使得无线充电芯片上电，然后执行步骤S110。或者在其他无线充电芯片固件升级事件被触发后，开启无线OTG，通过无线OTG功能使得无线充电芯片。当无线充电芯片固件升级完成后，关闭无线OTG。
进一步的，利用第二固件完成对无线充电芯片固件的升级，还可以包括：重启无线充电芯片。当第二固件被写入无线充电芯片后，需要重启无线充电芯片以运行第二固件。
