The memory size of the non-volatile flash memory module adopted in this embodiment is limited to 32M, and the actual capacity is 29.4M.
本实施例的一体机在正常使用时，Windows终端可连接网络并从后台下载与该一体机所对应机型的安卓***的最小***并存储在Windows终端的硬盘中；最小***只能够让这个一体机的安卓模块运行起来并进行网络连接，其最小***删除了大量的预置应用和后台服务，使得最小***包的内存大小可控制在400M以内。When the all-in-one machine of this embodiment is in normal use, the Windows terminal can connect to the network and download the minimum system of the Android system of the model corresponding to the all-in-one machine from the background and store it in the hard disk of the Windows terminal; the minimum system can only make this all-in-one The Android module of the machine runs and connects to the network, and its minimum system deletes a large number of preset applications and background services, so that the memory size of the minimum system package can be controlled within 400M.
本实施例的一体机和Windows终端在完成上述连接和下载操作后，当一体机出现故常主***无法正常运行时，即可通过本实施例的***修复方法对一体机进行***重装维护，本实施例的***修复方法具体包括如下步骤：After the all-in-one machine and Windows terminal in this embodiment complete the above connection and download operations, when the all-in-one machine fails and the main system cannot run normally, the system repair method of this embodiment can be used to perform system reinstallation and maintenance on the all-in-one machine. The system repair method of the embodiment specifically includes the following steps:
当一体机内置的主***出现故障时，与所述主***相连的微控单元多次接收Windows终端发送的最小***的局部固件数据，直至Windows终端将与所述主***相匹配的最小***的所有数据均发送完毕；When the built-in main system of the all-in-one fails, the micro-control unit connected to the main system receives the local firmware data of the minimum system sent by the Windows terminal for many times until the Windows terminal will match the minimum system data of the main system. All data has been sent;
所述微控单元将每次接收所得的局部固件数据经所述主***的非易失闪存模块转存至所述主***的uboot中，使得所述一体机运行最小***后连接升级服务器，并从所述升级服务器中下载完整升级包以执行***修复操作。The micro-control unit transfers the local firmware data received each time to the uboot of the main system through the non-volatile flash memory module of the main system, so that the all-in-one machine is connected to the upgrade server after running the minimum system, and Downloading a complete upgrade package from the upgrade server to perform a system repair operation.
由于一体机在开机正常启动时其微控单元会跟安卓***进行通信，并获取安卓***的运行状态，一旦安卓***无法正确的发送运行状态的时候，则可判定安卓***出现了故障；在安卓***损坏时，uboot还是会正常工作，uboot主要作用是用来启动操作***内核；即使一体机无法进入***，也会一直在UBOOT模式下运行，若在较长的指定时间内都未收到正常运行的指令，所述微控单元就知道安卓***已经损坏。Since the micro-control unit of the all-in-one machine will communicate with the Android system when it starts up normally, and obtain the operating status of the Android system, once the Android system cannot correctly send the operating status, it can be determined that the Android system has failed; When the system is damaged, uboot will still work normally. The main function of uboot is to start the operating system kernel; even if the all-in-one machine cannot enter the system, it will always run in UBOOT mode. According to the instruction of running, the micro control unit just knows that the Android system has been damaged.
如图1所示，当所述微控单元获知所述主***出现故障时，所述微控单元将其用于与Windows终端连接的串口切换至第一模式；该第一模式为高速状态模式，波特率为2M/s，通常情况下为115200/s，在高速模式下可实现数据传输。As shown in Figure 1, when the micro-control unit learns that the main system fails, the micro-control unit switches the serial port used to connect with the Windows terminal to the first mode; the first mode is a high-speed state mode , the baud rate is 2M/s, usually 115200/s, and data transmission can be realized in high-speed mode.
此时，Windows终端将预先下载好的最小***的局部固件数据发送至所述微控单元；其中，所述Windows终端预先按照所述非易失闪存模块的内存限制将其下载的最小***划分为多个局部固件数据，以确保所述Windows终端每次发送的局部固件数据的内存大小均小于或等于所述非易失闪存模块的内存限制。本实施例中，Windows终端每次发送28M的固件数据到微控单元，直至大约400M内存大小的最小***中的所有数据全部发送至微控单 元中。At this point, the Windows terminal sends the pre-downloaded partial firmware data of the minimum system to the micro-control unit; wherein, the Windows terminal divides the downloaded minimum system according to the memory limit of the non-volatile flash memory module into A plurality of partial firmware data, to ensure that the memory size of the partial firmware data sent by the Windows terminal each time is less than or equal to the memory limit of the non-volatile flash memory module. In this embodiment, the Windows terminal sends 28M firmware data to the MCU each time, until all the data in the smallest system with a memory size of about 400M are all sent to the MCU.
所述微控单元每次接收到Windows终端通过高速状态串口发送的28M的局部固件数据后，将28M局部固件数据通过SPI写入nor flash中，当写入完成后，所述微控单元将串口切换为第二模式以通过第二模式的串口向所述主***发送USB识别需求，而该第二模式为低速状态模式，其数据传输速度低于第一模式的数据传输速度。After the micro-control unit receives the 28M partial firmware data sent by the Windows terminal through the high-speed state serial port each time, the 28M partial firmware data is written in the nor flash through the SPI, and when the writing is completed, the micro-control unit writes the serial port Switch to the second mode to send the USB identification request to the host system through the serial port of the second mode, and the second mode is a low-speed state mode, and its data transmission speed is lower than that of the first mode.
所述微控单元通过低速状态的串口发送USB识别需求的消息给安卓***的uboot，让其进入升级模式并检测USB接口，从而识别到所述微控单元的USB接口，此时所述微控单元再把nor flash里面存储的局部固件数据通过USB接口发送到uboot里面，发送完数据后，擦除nor flash里面的数据，再将串口切换到高速模式，通知Windows终端再将下一个28M的局部固件数据发送给微控单元，微控单元存储完后再跟前述步骤一样将数据送到uboot里面，依次进行，直至Windows终端将其下载的最小***的所有数据均发送完毕，此时uboot也就完成了安卓最小***的升级。The micro-control unit sends the message of USB identification requirement to the uboot of the Android system through the serial port in the low-speed state, allowing it to enter the upgrade mode and detect the USB interface, thereby identifying the USB interface of the micro-control unit. At this time, the micro-control unit The unit then sends the partial firmware data stored in the nor flash to the uboot through the USB interface. After sending the data, erase the data in the nor flash, then switch the serial port to high-speed mode, and notify the Windows terminal to transfer the next 28M partial The firmware data is sent to the micro-control unit. After the micro-control unit is stored, it will send the data to uboot in the same way as the previous steps, and proceed in sequence until the Windows terminal has sent all the data of the minimum system it downloaded. At this time, uboot will Completed the upgrade of the Android minimum system.
一体机升级最小***可让安卓模块运行起来并进行网络连接，此时用户设置好安卓模块的网络连接后，安卓***的升级服务就会连接到一体机产品的升级服务器，该升级服务器中预先存储有不同机型所对应的完整升级包，一体机连接到升级服务器后下载一体机所属机型的完整安卓升级包进行固件升级，此时一体机内置的主***就是一个完整的***，实现了一体机***重装维护的目的。The minimal upgrade system of the all-in-one machine allows the Android module to run and connect to the network. At this time, after the user sets up the network connection of the Android module, the upgrade service of the Android system will be connected to the upgrade server of the all-in-one product. There are complete upgrade packages corresponding to different models. After the all-in-one machine is connected to the upgrade server, download the complete Android update package of the model to which the all-in-one machine belongs to upgrade the firmware. At this time, the built-in main system of the all-in-one machine is a complete system, realizing the integration The purpose of machine system reinstallation maintenance.
