与现有技术相比， 本申请包括以下优点：
当 SD接口不支持 SDIO功能时，移动终端和 SD接口的通信设备只能以文件 为单位读写安全数码存储器中的数据， 本申请中， 安全数码存储器可以定义特 殊文件，用于将升级开始命令和升级数据存储至不同文件中，使移动终端和 SD 接口的通信设备可以通过识别文件名称，获知文件中所存储的数据是升级开始 命令还是升级数据。
在本申请中，安全数码存储器中存储有命令交换文件和固件升级文件这两 个特殊文件，这两个特殊文件中所述命令交换文件中存储有移动终端写入的升 级开始命令， 固件升级文件中存储有升级数据， SD接口的通信设备通过识别 文件名称可以在相应文件中获取固件升级过程所需数据。
当 SD接口的通信设备获取到命令交换文件中的升级开始命令时， 表明 SD 接口的通信设备开始执行固件升级， 则 SD接口的通信设备会进一步从安全数 码存储器中读取存储有升级数据的固件升级文件， 再将固件升级文件写入到 Flash存储器中， 完成固件升级。 附图说明

本申请可用于众多通用或专用的计算装置环境或配置中。 例如： 个人计 算机、 服务器计算机、 手持设备或便携式设备、 平板型设备、 多处理器装 置、 包括以上任何装置或设备的分布式计算环境等等。 下面将结合本申请实施例中的附图， 对本申请实施例中的技术方案进行 清楚、 完整地描述， 显然， 所描述的实施例仅仅是本申请一部分实施例， 而 不是全部的实施例。 基于本申请中的实施例， 本领域普通技术人员在没有做 出创造性劳动前提下所获得的所有其他实施例， 都属于本申请保护的范围。
实施例 1 本申请实施例 1提供的固件升级方法应用于通过 SD接口与移动终端进行 数据通信的 SD接口的通信设备， 且所述 SD接口的通信设备包括 SD存储器 和 Flash存储器， 所述 SD存储器中存储有命令交换文件， 其中所述 SD存储 器是指所述移动终端通过所述 SD接口访问的存储器， 所述 Flash存储器是指 所述 SD 接口的通信设备内部保存固件的存储器。 固件是指写入 EPROM ( Erasable Programmable Read Only Memory, 可擦除可编程只读寄存器）或者 EROM ( Eraseable Read Only Memory,可擦只读存储器 ) 中的程序代码， 更简 单的说， 固件是 BIOS ( Basic Input Output System, 基本输入输出系统） 的软 件， 是固化在集成电路内部的程序代码， 负责控制和协调集成电路的功能。 在本申请实施例中， 移动终端不能直接访问 Flash存储器， 所以移动终端 不能直接更改 Flash存储器中的数据。 SD存储器和 Flash存储器在物理硬件上 可以是不同的两颗芯片， 也可以共用一颗芯片。 需要说明的是： 本申请实施例中的 SD接口不支持 SDIO功能， 当 SD接 口不支持 SDIO 功能时， 移动终端只能以文件为单位读写 SD存储器中的数 据， 因此 SD存储器中可以定义特殊文件， 用于将升级开始命令和升级数据存 储至不同文件中， 使 SD接口的通信设备可以通过识别文件名称， 获知文件中 的数据是升级开始命令还是升级数据。 其中 SD存储器的特殊文件分别是命令 交换文件和固件升级文件这两个特殊文件， 这两个特殊文件中所述命令交换 文件中存储有移动终端写入的升级开始命令， 固件升级文件中存储有升级数 据， SD接口的通信设备在相应文件中获取固件升级过程所需数据。 请参阅图 1 , 其示出了本申请实施例 1 提供的一种固件升级方法的流程 图， 可以包括以下步骤： 步骤 101 : 获取所述命令交换文件中的升级开始命令。 在本实施例中， 与 SD接口的通信设备进行数据通信的移动终端会检测 SD接口的通信设备上的固件程序与服务器上保存的 SD接口的通信设备的固 件程序的版本号是否一致， 当检测到版本号不一致时， 判定出 SD接口的通信 设备的固件程序需要升级， 移动终端将升级开始命令写入到命令交换文件 中。 命令交换文件的格式可以任意自定义， 例如将命令交换文件定义为二进 制文件。 命令交换文件中的升级开始命令可以由移动终端通过 SCSI ( Small Computer System Interface, 小型计算机系统接口）命令写入到命令交换文件 中。
SCSI命令将升级开始命令写入到命令交换文件中可以为： REQ 1 u。 其 中 REQ表示该命令是升级开始命令， 1是命令序号， u表示开始升级命令。 需要说明的是： 命令交换文件中可以写入多个升级开始命令。 为了区分 不同升级开始命令， 以不同命令序号标识升级开始命令。 如 REQ 1 u表示第 一次升级开始命令， REQ 2 u表示第二次升级开始命令。 本实施例仅列举了 一种写入升级开始命令的方式和一种升级开始命令的格式， 对于其他写入方 式和命令格式也属于本实施例保护范围， 对此本实施例不再——列举。 步骤 102: 在获取到所述升级开始命令后， 从所述 SD存储器中读取存储 有升级数据的固件升级文件， 其中所述固件升级文件由移动终端从服务器上下载并由所述移动终端写 入到所述 SD存储器中。 升级数据包含有用于升级 SD接口的通信设备的固件 的程序代码。
其中固件升级文件是一个二进制文件， 可以包括文件信息头， 固件数据 和校验信息。 在本实施例中固件升级文件的格式与现有二进制文件的格式相 同， 对此本实施例不再加以阐述。 当 SD接口的通信设备获取到升级开始命令后， 表明 SD接口的通信设备 开始进行固件升级， 则 SD接口的通信设备会从 SD存储器中获取固件升级文 件。 需要指出的是： 移动终端在检测到接口的通信设备上的固件程序与服务 器上保存的 SD接口的通信设备的固件程序的版本号不一致情况下， 首先下载 固件升级文件， 并将其写入到 SD存储器中。 移动终端在固件升级文件全部写 入后， 再将升级开始命令写入到 SD存储器的命令交换文件中， 以保证 SD接 口的通信设备在开始固件升级时， 固件升级文件已全部写入到 SD存储器， 避 免由于文件中升级数据不全导致升级失败。
步骤 103: 将所述固件升级文件写入到所述 Flash存储器中。 在本实施例中， 固件升级原理是将新的固件升级文件中的程序代码写入 到 Flash存储器中， 覆盖 SD接口的通信设备之前启动时所读取的保存在 Flash 存储器中的程序代码， 因此 SD接口的通信设备在获取到固件升级文件后， 会 进一步将固件升级文件写入到 Flash存储器中， 以将 Flash存储器中之前保存 的程序代码更改为当前写入到 Flash存储器中固件升级文件中的程序代码， 完 成对 SD接口的通信设备的固件升级。 上述 SD接口的通信设备和移动终端在进行数据通信时， 不同文件中具有 不同数据， 从而移动终端可以通过识别文件名称， 将不同数据写入到对应的 文件中， SD接口的通信设备可以通过识别文件名称， 获知移动终端写入的数 据是升级开始命令还是升级数据。 当 SD接口的通信设备获取到命令交换文件 中的升级开始命令时， 表明 SD接口的通信设备开始执行固件升级， 则 SD接 口的通信设备会进一步从安全数码存储器中读取存储有升级数据的固件升级 文件， 再将固件升级文件写入到 Flash存储器中， 完成固件升级。 需要指出的是： 部分 SD接口可以支持 SDIO功能， 当移动终端和 SD接 口的通信设备之间用于数据通信的 SD接口支持 SDIO功能， 则 SD接口的通 信设备可以釆用本实施例提供的固件升级方法， 也可以釆用基于 SDIO功能的 现有固件升级方法。
实施例 2 上述实施例 1所阐述的固件升级方法解决了当 SD接口不支持 SDIO功能 时， SD接口的通信设备的固件升级问题， 但是由于 SD接口的通信设备上不 具有可用于人机交互的接口， 所以固件升级进度和状态无法在 SD接口的通信 设备中进行显示。 本申请实施例 2 提供的固件升级方法可以由移动终端显示 固件升级进度和状态。 本申请实施例 2所提供的固件升级方法应用于通过 SD接口与移动终端进 行数据通信的 SD接口的通信设备， 且所述 SD接口的通信设备包括 SD存储 器和 Flash存储器， 所述 SD存储器中存储有命令交换文件和结果交换文件， 其中所述 SD存储器是指所述移动终端通过所述 SD接口访问的存储器， 所述 Flash存储器是指所述 SD接口的通信设备内部保存固件的存储器。 请参阅图 2 , 其示出了本申请实施例 2提供的一种固件升级方法的另一种 流程图， 可以包括以下步骤： 步骤 201 : 获取所述命令交换文件中的升级开始命令， 其中所述升级开 始命令由所述移动终端写入到所述命令交换文件中。 步骤 202: 在获取到所述升级开始命令后， 从所述 SD存储器中读取存储 有升级数据的固件升级文件， 其中所述固件升级文件由移动终端下载并由所 述移动终端写入到所述安全数码存储器中。 步骤 203: 将所述固件升级文件写入到所述 Flash存储器中。 在本实施例中， 步骤 201至步骤 203的具体实施过程与步骤 101至步骤 103的具体实施过程相同， 对此本实施例不再加以阐述。 步骤 204: 在将所述固件升级文件写入所述 Flash存储器的过程中， 将升 级进度写入到所述结果交换文件中。 步骤 205: 在将所述固件升级文件写入所述 Flash存储器之后， 将所述升 级结果写入到所述结果交换文件中。 其中升级进度表明当前固件升级文件写入到 Flash存储器的进度， 如以写 入到 Flash存储器中文件大小占固件升级文件总大小的百分比来表明升级进 度。 升级结果表明升级的最终结果， 如升级成功和升级失败。 在本实施例 中， SD接口的通信设备可以以不同标识表明升级成功或升级失败。
在本实施例中， 升级进度和升级结果可以通过 SCSI命令写入到结果交换 文件中。 将升级进度写入到所述结果交换文件中的 SCSI命令可以为： RSQ 1 m% , 其中， 1 是命令序号， 与升级开始命令的命令序号对应， m%表示进 度。 SD接口的通信设备在每次进行固件升级时可以周期性更改升级进度。 将升级结果写入到所述结果交换文件中的 SCSI命令可以为： RSP l s, 其 中， 1是命令序号， 与升级开始命令的命令序号对应， s表示升级成功， 如果 升级失败， 则返回 f表示升级失败。 当移动终端查询固件升级状态时， 可以从 SD存储器中获取结果交换文 件。 当移动终端获取到结果交换文件后， 进而获取结果交换文件中的升级进 度和升级结果， 从而在移动终端上显示固件升级进度和状态， 以解决 SD接口 的通信设备不包括显示屏导致的无法显示固件升级进度和状态的问题。 从上 述可以看出， 本申请实施例 2 提供的固件升级方法在实现固件升级的同时， 还可以在移动终端上显示固件升级进度和状态。 移动终端从 SD存储器中获取结果交换文件的具体过程可以是： SD接口 的通信设备在获取到命令交换文件中升级状态查询命令后， 将所述结果交换 文件发送至所述移动终端， 其中升级状态查询由移动终端写入到命令交换文 件中， 其表明移动终端需要查询固件升级过程， 此时 SD接口的通信设备需要 发送结果交换文件至移动终端。
在本实施例中， 升级状态查询命令也可以通过 SCSI写入到命令交换文件 中， 如 REP 1 q。 其中 REP表示该命令是升级状态查询命令， 1是命令序号， u表示开始状态查询。 需要说明的是： 结果交换文件的格式可以任意自定义， 例如结果交换文 件可以釆用现有的二进制文件的格式。 结果交换文件中可以写入多个升级结 果。 为了区分不同升级结果， 升级结果以不同命令序号标识升级结果， 并且 杯 。 如 REQ 1 u表示 第一次升级开始命令， 其对应的升级结果可以为 RSP 1 s„ 而 REQ 2 u表示第 二次升级开始命令， 其对应的升级结果可以为 RSP 2 s。 本实施例仅列举了一 种写入升级状态查询命令的方式和一种升级状态查询命令的格式， 对于其他 写入方式和命令格式也属于本实施例保护范围， 对此本实施例不再——列 举。
实施例 3 请参阅图 3 , 其示出了本申请实施例 3提供的固件升级方法的再一种结构 示意图， 应用于通过 SD接口与移动终端进行数据通信的 SD接口的通信设 备， 且所述 SD接口的通信设备包括 SD存储器和 Flash存储器， 所述 SD存储 器中存储有命令交换文件， 其中所述 SD存储器是指所述移动终端通过所述 SD接口访问的存储器， 所述 Flash存储器是指所述 SD接口的通信设备内部保 存固件的存储器。 上述图 3所示的固件升级方法可以包括以下步骤： 步骤 301 : 获取所述命令交换文件中的升级开始命令， 其中所述升级开 始命令由所述移动终端写入到所述命令交换文件中。 步骤 302: 在获取到所述升级开始命令后， 从所述安全数码存储器中读 取存储有升级数据的固件升级文件， 其中所述固件升级文件由移动终端下载 并由所述移动终端写入到所述安全数码存储器中。 步骤 303: 将所述固件升级文件写入到所述 Flash存储器中。 在本实施例中， 步骤 301至步骤 303的具体实施过程与步骤 101至步骤 103的具体实施过程相同， 对此本实施例不再加以阐述。 步骤 304: 在将所述固件升级文件全部写入到所述 Flash存储器后， 删除 所述命令升级文件中的所述升级开始命令。
因为命令升级文件中可以写入多个升级开始命令， 所以为了避免下一次 升级时， 受上次升级后在命令交换文件中遗留的升级开始命令的干扰。 在将 所述固件升级文件全部写入到 Flash存储器后， 删除命令升级文件中写入的升 级开始命令。 当然， 应用上述图 3所示的固件升级方法的 SD接口的通信设备中， SD 存储器中还存储有结果交换文件， 所述结果交换文件中可以存储有升级进度 和升级结果， 并且该结果交换文件还可以发送到移动终端， 在移动终端上显 示升级进度和升级结果， 具体可以参阅图 2 所示的固件升级方法中的关于结 果交换文件的详细说明， 对此本实施例不再加以阐述。
上述所有方法实施例提供的固件升级方法需要在 SD接口的通信设备的升 级模式下进行， 而 SD接口的通信设备在开机后运行在普通运行模式下， 因此 当 SD接口的通信设备在获取到升级开始命令后， 需要重启所述安全数码接口 的通信设备， 进入安全数码接口的通信设备的升级模式， 然后在升级模式 下， 从所述安全数码存储器中读取存储有升级数据的所述固件升级文件。 在 将所述固件升级文件全部写入到所述 Flash存储器后， 重启所述安全数码接口 的通信设备， 进入所述安全数码接口的通信设备的普通运行模式。 其中普通运行模式是指 SD接口的通信设备所运行的操作系统可以为用户 提供各种业务功能的运行模式， 升级模式是指 SD接口的通信设备运行的操作 系统可以为用户仅提供升级业务功能的运行模式。 在上述所有方法实施例中， SD接口的通信设备在将固件升级文件写入 Flash存储器中可以包括： 将固件升级文件镜像写入 Flash存储器中， 即将固 件升级文件中新的程序代码覆盖 Flash存储器中原有保存的程序代码。 当新的 程序代码完整被写入到 Flash存储器中时， SD接口的通信设备的固件升级完 成。 当 SD接口的通信设备再次运行时， 则可以直接运行 Flash存储器中的新 的程序代码。
当然， 在上述所有实施例中， 固件升级文件全部写入到 SD存储器后，
SD接口的通信设备需要进一步校验固件升级文件， 以判断固件升级文件是否 为合法文件， 从而防止 Flash存储器中写入非法文件导致 SD接口的通信设备 运行出错现象的发生， 其中合法文件表明固件升级文件为可使用， 且未被除 运营商之外的其他用户更改的文件。 在本实施例中， SD接口的通信设备校验 固件升级文件时可以釆用现有校验方法进行校验， 对此本实施例不再加以阐 述。
上述所有方法实施例都是从 SD接口的通信设备一侧进行阐述， 下面从移 动终端侧介绍本申请实施例提供的固件升级方法。 实施例 4 本申请实施例 4 提供的固件升级方法， 应用于移动终端， 所述移动终端 通过 SD接口与 SD接口的通信设备进行数据通信， 所述 SD接口的通信设备 包括 SD存储器和 Flash存储器， 所述 SD存储器中存储有命令交换文件， 其 中所述 SD存储器是指所述移动终端通过所述 SD接口访问的存储器， 所述 Flash存储器是指所述 SD接口的通信设备内部保存固件的存储器。 其中固件是指写入 EPROM或者 EROM中的程序。 在本申请实施例中 , 移动终端不能直接访问 Flash存储器， 所以移动终端不能直接更改 Flash存储 器中的数据。 SD 存储器和 Flash存储器在物理硬件上可以是不同的两颗芯 片， 也可以共用一颗芯片。
需要说明的是： 本申请实施例中的 SD接口不支持 SDIO功能， 当 SD接 口不支持 SDIO 功能时， 移动终端只能以文件为单位读写 SD存储器中的数 据， 因此 SD存储器中可以定义特殊文件， 用于将升级开始命令和升级数据存 储至不同文件中， 使 SD接口的通信设备可以获知文件中所存储的数据是升级 开始命令还是升级数据。 其中 SD存储器的特殊文件分别是命令交换文件和固 件升级文件这两个特殊文件， 移动终端可以将升级开始命令和升级数据分别 写入到这两个特殊文件中， 并且 SD接口的通信设备在相应文件中获取固件升 级过程所需数据。 请参阅图 4, 其示出了本申请实施例 4提供的一种固件升级方法的流程 图， 可以包括以下步骤： 步骤 401 : 下载存储有升级数据的固件升级文件。 在本实施例中， 移动终端会检测 SD接口的通信设备上的固件程序与服务 器上保存的 SD接口的通信设备的固件程序的版本号是否一致， 当检测到版本 号不一致时， 判定出 SD接口的通信设备的固件程序需要升级， 则移动终端从 服务器中下载存储有升级数据的固件升级文件。 其中固件升级文件是一个二进制文件， 可以包括文件信息头， 固件数据 和校验信息。 在本实施例中固件升级文件的格式与现有二进制文件的格式相 同， 对此本实施例不再加以阐述。 步骤 402: 将所述固件升级文件写入到所述 SD存储器中。 步骤 403: 在固件升级文件全部写入到所述 SD存储器后， 将移动终端内 的升级开始命令写入到所述命令交换文件中， 由所述 SD接口的通信设备获取 所述升级开始命令进行固件升级。 在固件升级文件全部写入到 SD存储器后， 移动终端进一步在命令交换文 件中写入升级开始命令。 SD接口的通信设备通过识别文件名称可知命令交换 文件中存储有升级开始命令， 则 SD接口的通信设备会轮询所述命令升级文 件， 以在所述升级开始命令写入完成后， 获取所述升级开始命令。 其中轮询 命令升级文件是指周期性查询命令升级文件中是否已经写入完整的升级开始 命令。
当 SD接口的通信设备获取到升级开始命令后， 表明 SD接口的通信设备 开始进行固件升级， 则 SD接口的通信设备会进一步获取固件升级文件， 并将 固件升级文件写入 Flash存储器中， 以完成固件升级。 需要说明的是， 固件升级文件的写入优于升级开始命令写入， 以保证写 入到 SD存储器中固件升级文件的完整性， 从而避免在升级开始命令执行时， SD存储器中的固件升级文件不完整而导致升级失败的情况发生。 此外， SD接口的通信设备在进行固件升级过程中， 移动终端还会进一步 将升级状态查询命令写入到所述命令交换文件中。 当 SD接口的通信设备获取 到升级状态查询命令时， 会将结果交换文件发送到移动终端上。 所述结果交 换文件中写入有所述升级进度和升级结果， 因此移动终端在接收到结果交换 文件中， 可以在移动终端上显示升级进度和升级结果。 其中移动终端可以在每个固件升级过程中， 周期性将升级状态查询命令 写入到命令交换文件中， 当 SD接口的通信设备每获取到升级状态查询命令 时， 都会发送写入有升级进度的结果交换文件至移动终端， 从而移动终端可 以实时监测升级进度。 当 SD接口的通信设备获取到一次固件升级过程的最后 一次升级状态查询命令时， 即可以发送写入有最终升级进度和升级结果的结 果交换文件至移动终端， 从而在移动终端上显示最终的升级结果。 需要说明的是： 在本实施例中升级开始命令和升级状态查询命令可以通 过 SCSI命令写入， 其 SCSI命令格式可以参阅从 SD接口的通信设备侧所阐述 的固件升级方法， 对此本实施例不再加以介绍。 命令交换文件和结果交换文 件的格式可以任意自定义， 例如命令交换文件和结果交换文件可以釆用现有 的二进制文件的格式。
实施例 5 与上述实施例 1 所示的方法实施例， 本实施例提供了一种固件升级装 置， 所述固件升级装置应用于通过 SD接口与移动终端进行数据通信的 SD接 口的通信设备， 且所述 SD接口的通信设备包括 SD存储器和 Flash存储器， 所述 SD存储器中存储有命令交换文件， 其中所述 SD存储器是指所述移动终 端通过所述 SD接口访问的存储器， 所述 Flash存储器是指所述 SD接口的通 信设备内部保存固件的存储器。 固件是指写入 EPROM或者 EROM中的程序 代码。 需要说明的是： 与 SD接口的通信设备进行数据通信的移动终端不能直接 访问 Flash存储器， 所以移动终端不能直接更改 Flash存储器中的数据。 SD存 储器和 Flash存储器在物理硬件上可以是不同的两颗芯片， 也可以共用一颗芯 片。
在本实施例中， SD接口不支持 SDIO功能， 当 SD接口不支持 SDIO功能 时， 移动终端只能以文件为单位读写 SD存储器中的数据， 因此 SD存储器中 可以定义特殊文件， 用于将升级开始命令和升级数据存储至不同文件中， 使 SD接口的通信设备可以通过识别文件名称， 获知文件中的数据是升级开始命 令还是升级数据。 其中 SD存储器的特殊文件分别是命令交换文件和固件升级 文件这两个特殊文件， 这两个特殊文件中所述命令交换文件中存储有移动终 端写入的升级开始命令， 固件升级文件中存储有升级数据， SD接口的通信 设备在相应文件中获取固件升级过程所需数据。 请参阅图 5 , 其示出了本申请实施例提供的一种固件升级装置的一种结 构示意图， 可以包括： 第一获取单元 11、 读取单元 12和第一写入单元 13。 第一获取单元 11 , 用于获取所述命令交换文件中的升级开始命令， 其中 所述升级开始命令由所述移动终端写入到所述命令交换文件中。 当移动终端检测到接口的通信设备上的固件程序与服务器上保存的 SD接 口的通信设备的固件程序的版本号不一致时， 判定出 SD接口的通信设备的固 件程序需要升级， 移动终端则会将升级开始命令写入到命令交换文件中。 其 中升级开始命令表明 SD接口的通信设备中固件需要升级， 当第一获取单元 11获取到该升级开始命令， 开启固件升级。 命令交换文件的格式任意自定义， 例如将命令交换文件定义为二进制文 件。 命令交换文件中的升级开始命令可以由移动终端通过 SCSI ( Small Computer System Interface, 小型计算机系统接口）命令写入到命令交换文件 中， 具体格式可以参阅实施例 1中所列举的命令格式。 读取单元 12, 用于在获取到所述升级开始命令后， 从所述 SD存储器中 读取存储有升级数据的固件升级文件。 其中所述固件升级文件由移动终端下载并由所述移动终端写入到所述 SD 存储器中。 升级数据包含有用于升级 SD接口的通信设备的固件的程序代码。 固件升级文件是一个二进制文件， 可以包括文件信息头， 固件数据和校验信 息。 在本实施例中固件升级文件的格式与现有二进制文件的格式相同， 对此 本实施例不再加以阐述。 当读取单元 12获取到升级开始命令后， 表明 SD接口的通信设备开始进 行固件升级， 则 SD接口的通信设备会从 SD存储器中获取固件升级文件。 需要指出的是： 移动终端在检测到接口的通信设备上的固件程序与服务 器上保存的 SD接口的通信设备的固件程序的版本号不一致情况下， 首先下载 固件升级文件， 并将其写入到 SD存储器中。 移动终端在固件升级文件全部写 入后， 再将升级开始命令写入到 SD存储器的命令交换文件中， 以保证 SD接 口的通信设备在开始固件升级时， 固件升级文件已全部写入到 SD存储器， 避 免由于文件中升级数据不全导致升级失败。
第一写入单元 13 , 用于将所述固件升级文件写入到所述 Flash存储器中。 在本实施例中， 固件升级原理是将新的固件升级文件中的程序代码写入 到 Flash存储器中， 覆盖 SD接口的通信设备之前启动时所读取的保存在 Flash 存储器中的程序代码， 因此读取单元 12在获取到固件升级文件后， 会由第一 写入单元进一步将固件升级文件写入到 Flash存储器中， 以将 Flash存储器中 之前保存的程序代码更改为当前写入到 Flash存储器中固件升级文件中的程序 代码， 完成对 SD接口的通信设备的固件升级。
上述 SD接口的通信设备和移动终端在进行数据通信时， 不同文件中具有 不同数据， 从而移动终端可以通过识别文件名称， 将不同数据写入到对应的 文件中， SD接口的通信设备可以通过识别文件名称， 获知移动终端写入的数 据是升级开始命令还是升级数据。 当 SD接口的通信设备获取到命令交换文件 中的升级开始命令时， 表明 SD接口的通信设备开始执行固件升级， 则 SD接 口的通信设备会进一步从安全数码存储器中读取存储有升级数据的固件升级 文件， 再将固件升级文件写入到 Flash存储器中， 完成固件升级。
