step S11: and creating a partition information table corresponding to each embedded memory, and correspondingly storing the partition information in the partition table in a structural information mode, wherein the partition information table comprises a partition table name and a partition full name uniquely corresponding to the partition.
Further, the partition information table includes structure item _ part _ info structure information of all partitions of the embedded memory in a sequential order: partition names, partition aliases, partition system formats, and partition lengths; the partition full name includes the partition name and the partition alias, and the partition information table fully includes all the partitions of the two emmcs as above.
In the above steps, for example, a mobile terminal that has been able to successfully drive two pieces of eMMC using u-boot is used, the two pieces of eMMC are respectively numbered 0(QNX system) and 1(Android), and for example, when a command "mmc dev 0" or "mmc dev 1" is input, the eMMC can be normally detected. Partition tables are respectively established for eMMC0 and eMMC 1 according to the use requirements of the QNX and the Android system on the eMMC, and are respectively stored in oem _ partition _ table _0 and oem _ partition _ table _1 in a structure information mode of struct item _ partition _ info. For example, the oem _ partition _ table _0 and oem _ partition _ table _1 partition information table specific information is as follows:
table-partition information table
It should be noted that, when a partition is unified for eMMC, it is necessary to ensure that all partition full names are unique, where a partition full name indicates a character string composed of a partition name and a partition alias, such as a system _ a partition, and in the partition table, the partition name is "system" and the partition difference name is "_ a", so the partition full name is "system _ a".
Step S12: and reading the partition information table, identifying the corresponding embedded memories according to the partition table names, and uniformly partitioning one or more embedded memories according to the partition information table.
Accordingly, FIG. 2 shows a flow chart of partitioning embedded memory. The mobile terminal comprises two eMMC0 and eMMC 1, a partition information table oem _ partition _ table _0 and oem _ partition _ table _1 is read, according to the whole partition name, the eMMC on which the partition is located is automatically identified, the partition information table is written into the corresponding eMMC, the eMMC is partitioned, and after the partition succeeds, the partition table structures of the eMMC0 and the eMMC 1 are shown in the figure 3.
In the above steps, the method further comprises the steps of identifying the command of the mobile terminal, judging the embedded memory needing to be operated according to the command of the mobile terminal, and storing the judgment result; and directly partitioning the embedded memory according to the judgment result.

FIG. 4 is a schematic diagram of a u-boot end and PC end communication model. The software program of the invention can run in various bootloaders meeting the requirements, but the realization of the invention is mainly realized in u-boot, so in the example of the invention, the muti _ fastboot exists as application program software on the u-boot. The invention follows a fastboot protocol, and can manage a plurality of eMMC in multiple dimensions so as to meet the requirement of the operation of a novel operating system. And the fastboot service at the PC end is fully compatible with the conventional fastboot. The program designed by the invention realizes communication with the faceboot service of the PC end by the USB, and the program is used as the USB device end. And when the mobile terminal u-boot end realizes muti _ fastboot communication, a data transmission protocol completely follows a standard fastboot protocol, the PC end fastboot serves as a server end, and the muti _ fastboot at the u-boot end serves as a client end.
During the process of updating the machine, the muti _ fastboot can support independent support for a certain eMMC (for example, only the eMMC0 is operated, and the command: muti _ fastboot mmc 0) and can also support 2 eMMC simultaneously, during the process of updating the machine specifically, the serial number of the corresponding eMMC is automatically found according to the partition name, and then the corresponding eMMC is operated. Taking the u-boot end flush mode including eMMC0 and eMMC 01 as an example, the command is exemplified as follows:
1. single flash eMMC0
(1) u-boot end command:
(2) PC end command:
brushing the machine according to the subareas:
fastboot flash{partition}{image_file}
an example of a command is as follows:
fastboot flash dos dos.img
fastboot flash qnxdisk qnxdata.img
erasing the subareas:
fastboot erase{partition}
an example of a command is as follows:
fastboot erase dos
fastboot erase qnxdisk
formatting:
formatting a partition:
fastboot format{partition}
an example of a command is as follows:

global formatting, reestablishing a partition table:
fastboot oem format
2. single-brush eMMC 1
(1) u-boot end command:
(2) PC end command:
brushing the machine according to the subareas:
fastboot flash{partition}{image_file}
an example of a command is as follows:
fastboot flash dtb dtb.img
fastboot flash dtbo dtbo.img
fastboot flash boot boot.img
fastboot flash metadata metadata.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot flash product product.img
erasing the subareas:
fastboot erase{partition}
an example of a command is as follows:
fastboot erase misc
fastboot erase pst
fastboot erase vbmeta
fastboot erase dtb
fastboot erase dtbo
fastboot erase boot
fastboot erase metadata
fastboot erase system
fastboot erase vendor
fastboot erase qnxdisk
fastboot erase product
fastboot erase userdata
formatting:
formatting a partition:
fastboot format{partition}
fastboot format userdata
global formatting, reestablishing a partition table:
fastboot oem format
it should be noted that for a system using a/B partition, because the a/B partition is mainly used for OTA upgrade and the like, the muti _ fastboot is flushed only for a certain partition in the a/B, and this option may select a setting in the implementation of the muti _ fastboot. That is, assuming that the a partition has been set for system boot, when the PC executes the command: img when a fastboot flash system is flushed, only system _ a partition is flushed, and system _ b partition is ignored.
3. Automatic brushing machine according to subareas
1) u-boot end command:
muti_fastboot mmc
(2) PC end command:
the command of the PC end is completely the same as the commands in 1 and 2, after the command is executed, the u-boot end automatically installs the transmitted partition names to search the serial number of the eMMC, and then the corresponding eMMC partition is operated.
PC terminal fastboot common instruction
Loading kernel operation according to u-boot parameters:
fastboot boot
and (4) restarting:
fastboot reboot
fastboot reboot bootloader
reading version information:
fastboot getver:version
as can be known from the above description about the cooperative communication flashing upgrade of the fastboot at the PC end and the muti _ fastboot at the u-boot end, the embodiment completely follows the fastboot protocol standard, and mainly performs synchronous unified management on the eMMC0 and the eMMC 1, so as to reduce the difference in use to the maximum extent, and make the use of the user simpler and more convenient.
