Abstract
Provided are a high-capacity eMMC mirror image manufacturing method and apparatus, which are applied to the technical field of eMMC manufacturing. The capacity reserved for a user partition in a high-capacity smart device eMMC is relatively high, but not too much of the user partition is used by application software the first time. If a small data partition is customized in the user partition to store data of pre-installation of the application software, the storage capacity of master slice firmware corresponding to the eMMC can be reduced. By merely subjecting the data partition to ext4 formatting after a shipped intelligent device is powered on the first time, the original storage capacity size of the user partition can be restored. The method comprises: creating a data partition; loading an n partition, and importing an ext4 file system pre-stored in the n partition into firmware to prepare master slice firmware; writing and burning the ext4 file system in the master slice firmware into an eMMC single slice; and loading an m partition, and performing ext4 file system formatting on the data partition. In the method, since an ext4 file system partition is imported into firmware, an eMMC master slice does not need to be taken out, thereby improving the data transmission speed.

S300，将母片固件中的ext4文件***回写烧录至emmc单片中；S300: Write back and burn the ext4 file system in the master firmware to the emmc single chip;
制成母片固件后，智能设备将存储于母片固件中的ext4文件***回写烧录至emmc单片，可以是将母片固件中的ext4文件***回写烧录至单个的emmc单片中，也可以是将母片固件中的ext4文件***回写烧录至多个emmc单片中，实现emmc单片量产，且无需卸下母片固件。After the master firmware is made, the smart device will write back and burn the ext4 file system stored in the master firmware to the emmc single chip, which can be written back and burn the ext4 file system in the master firmware to a single emmc single chip , It can also write back and burn the ext4 file system in the master firmware to multiple emmc monolithic chips to realize the mass production of emmc monolithic chips, and there is no need to remove the master firmware.
S400，加载m分区，对data分区进行ext4文件***的格式化。S400: Load the m partition, and format the data partition with an ext4 file system.
需要说明，此步骤不是由批量生产emmc的智能设备进行执行，而是在用户使用时进行的步骤，当用户操作智能设备首次开机时，加载m分区，对data分区进行ext4文件***的格式化。It should be noted that this step is not performed by the smart device of mass-produced emmc, but is performed when the user uses it. When the user operates the smart device for the first time, load the m partition and format the data partition with the ext4 file system.
总结上述步骤S100～S400，参考附图2，为本申请的大容量emmc镜像制作方法的工艺流程图；Summarizing the above steps S100 to S400, refer to Figure 2, which is a process flow diagram of the method for making a large-capacity emmc mirror image of this application;
首先，工人启动智能设备；First, the worker turns on the smart device;
智能设备检测该智能设备的emmc母片的Fac_version_flag标签的值是否为1，该Fac_version_flag标签是区分emmc为工厂生产版本或用户使用版本的标签；工人预设Fac_version_flag标签的值存在1或0两种情况，当emmc的Fac_version_flag标签的值为1时，执行工厂生产版本，当emmc的Fac_version_flag标签的值为0时，执行用户使用版本；需要说明，在执行emmc单片镜像制作过程中，emmc母片的Fac_version_flag标签的值默认为1，当emmc单片生产完毕且格式化后，将emmc单片的Fac_version_flag标签的值设置为0。The smart device detects whether the value of the Fac_version_flag tag of the emmc master chip of the smart device is 1. The Fac_version_flag tag is a tag that distinguishes the emmc as the factory production version or the user version; the worker presets the value of the Fac_version_flag tag to be 1 or 0. When the value of the Fac_version_flag tag of emmc is 1, the factory production version will be executed. When the value of the Fac_version_flag tag of emmc is 0, the user version will be executed; The value of the Fac_version_flag tag defaults to 1. When the emmc chip is produced and formatted, the value of the Fac_version_flag tag of the emmc chip is set to 0.
智能设备确定emmc母片的Fac_version_flag标签的值1，执行工厂生产版本的步骤；智能设备判断emmc母片的Fac_partition_flag标签的值是否为1；说明，工人预设Fac_partition_flag标签的值存在1或0两种情况，当emmc的Fac_partition_flag标签的值为1时，执行加载n分区的步骤(即执行步骤S200)，当emmc的Fac_partition_flag标签的值为0时，执行加载m分区的步骤(即直接跳转至步骤S400)；在执行emmc单片镜像制作过程中，emmc母片的Fac_partition_flag标签的值默认为1，当emmc单片生产完毕且格式化后，将emmc单片的Fac_partition_flag标签的值设置为0；The smart device determines the value of the Fac_version_flag tag of the emmc master chip to be 1, and executes the steps of the factory production version; the smart device determines whether the value of the Fac_partition_flag tag of the emmc master chip is 1; that the worker presets the value of the Fac_partition_flag tag to have two types: 1 or 0 In this case, when the value of the Fac_partition_flag tag of emmc is 1, the step of loading n partition is executed (that is, step S200), and when the value of Fac_partition_flag of emmc is 0, the step of loading m partition is executed (that is, jump directly to step S200). S400); During the execution of the emmc single-chip mirroring process, the value of the Fac_partition_flag tag of the emmc master chip is 1 by default. When the emmc single chip is produced and formatted, the value of the Fac_partition_flag tag of the emmc single chip is set to 0;
当上述的Fac_version_flag标签和Fac_partition_flag标签的至均为1时，执行工厂生产版本，加载n分区，智能设备将预存储于n分区中的ext4文件*** 导入至固件，制成母片固件；When the Fac_version_flag tag and the Fac_partition_flag tag above are both 1, the factory production version is executed, the n partition is loaded, and the smart device imports the ext4 file system pre-stored in the n partition to the firmware to make the master firmware;
随后，将母片固件中的ext4文件***回写至各个智能设备上的emmc单体上，此时，智能设备设置各个emmc单体的Fac_partition_flag标签的值为0，实现emmc的批量制作；Subsequently, the ext4 file system in the master firmware is written back to the emmc monomers on each smart device. At this time, the smart device sets the value of the Fac_partition_flag tag of each emmc monomer to 0 to realize the batch production of emmc;
经过工人的安装配置，将各个emmc单体一一对应安装至各智能设备中；After the installation and configuration of the workers, each emmc unit is installed into each smart device in a one-to-one correspondence;
安装有emmc单体的智能设备，识别emmc单体的Fac_partition_flag标签的值为0时，加载emmc单体的m分区表，对data分区进行ext4文件***的格式化，并将emmc单体的Fac_version_flag标签设置为0，从而去除用户使用的智能设备中的ext4文件***，无需制作与大容量emmc大小相当的母片，从而节约批量emmc单体烧录母片固件的时间，提高生产效率；When the smart device with the emmc monomer is installed, when the value of the Fac_partition_flag tag of the emmc monomer is 0, the m partition table of the emmc monomer is loaded, the data partition is formatted with the ext4 file system, and the Fac_version_flag tag of the emmc monomer Set to 0 to remove the ext4 file system in the smart device used by the user, and it is not necessary to make a master chip equivalent to the size of the large-capacity emmc, thereby saving the time for batch emmc monomers to burn the master chip firmware and improving production efficiency;
最终，用户的智能设备确定emmc单体的Fac_version_flag标签和Fac_partition_flag标签的值均为0时，则用户的智能设备往后进入用户使用版本，以用于正常使用。Finally, when the user's smart device determines that the values of the Fac_version_flag tag and the Fac_partition_flag tag of the emmc monomer are both 0, the user's smart device enters the user version later for normal use.
在一个实施例中，将预存储于n分区中的ext4文件***导入至固件，制成母片固件的步骤包括：In one embodiment, the steps of importing the ext4 file system pre-stored in the n partition into the firmware to make the master firmware include:
监听开机流程，在执行开机的一流程节点时，执行dd命令，dd命令为拷贝文件***指定大小数据的命令；Monitor the boot process, execute the dd command when executing a process node of booting, and the dd command is a command to copy data of a specified size in the file system;
根据dd命令将n分区中的ext4文件***导入至固件，制成母片固件；Import the ext4 file system in the n partition to the firmware according to the dd command to make the master firmware;
将母片固件命名为emmc.bin。Name the master firmware emmc.bin.
在一个实施例中，制成母片固件的步骤之后，对母片固件的有效性测试方法，包括：In one embodiment, after the step of making the master firmware, the method for testing the validity of the master firmware includes:
定位名称为emmc.bin的母片固件；Locate the master firmware named emmc.bin;
将名称为emmc.bin的母片固件按照dd命令回写至另一设备板卡对应的固件上；Write back the master firmware named emmc.bin to the corresponding firmware of another device board according to the dd command;
判断另一设备板卡上的固件是否能正常运行，若是，则确认母片固件为优品。Determine whether the firmware on the board of another device can operate normally, if so, confirm that the firmware of the master chip is excellent.
综上所述，大容量智能设备emmc中的用户分区预留的容量会比较大，但应用软件对用户分区的首次使用却并不多，如果在用户分区中定制一个小data分区，用来存储应用软件预安装的数据，就可以减小与emmc相对应的母片固件的存储量，仅需出厂智能设备首次上电后对data分区进行ext4的格式化，便可以恢复用户分区的存储量大小；方法为：创建data分区，data分区包括n分 区和m分区；加载n分区，将预存储于n分区中的ext4文件***导入至固件，制成母片固件；将母片固件中的ext4文件***回写烧录至emmc单片中；加载m分区，对data分区进行ext4文件***的格式化，该方法无需将emmc母片从智能设备中取下来，且因为将ext4文件***分区导入至固件，提升数据传输速度，有效的解决了目前大容量emmc单体在使用拷贝器拷贝容量大小相当的母片固件时，需要消耗很长的时间，以及目前劣品率高的技术问题。In summary, the reserved capacity of the user partition in the large-capacity smart device emmc will be relatively large, but the application software does not use the user partition for the first time. If a small data partition is customized in the user partition for storage The data pre-installed by the application software can reduce the storage capacity of the master firmware corresponding to the emmc, and only need to format the data partition to ext4 after the factory smart device is powered on for the first time to restore the storage capacity of the user partition ; The method is: create a data partition, which includes n partition and m partition; load n partition, import the ext4 file system pre-stored in n partition to the firmware, and make the master firmware; transfer the ext4 file in the master firmware System write-back and burn to emmc single chip; load m partition and format data partition with ext4 file system.
