According to the use requirements of QNX and Android systems on eMMC, partition tables are respectively built for eMMC 0 and eMMC 1, and are respectively stored in two tables of oem _part_table_0 and oem _part_table_1 in a manner of struct oem _part_info structure information. For example, 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 unifying the partitions to eMMC, it is necessary to ensure that all the partition full names are unique, where the partition full names represent character strings composed of partition names and partition aliases, such as system_a partition, and in the partition table, the partition names are "system", and the partition distinction names are "a", so the partition full names are "system_a".

Fig. 4 is a schematic diagram of a communication model between a u-boot terminal and a PC terminal. The software program of the invention can run in BootLoader meeting various requirements, but the implementation of the invention is mainly realized in u-boot, so muti _ fastboot exists as application software on u-boot in the example of the invention. The invention follows fastboot protocol, can manage multiple eMMCs in multiple dimensions to meet the running requirement of a novel operating system. And fastboot service at the PC end is fully compatible with conventional fastboot. The program designed by the invention realizes communication with fashboot service of the PC end by using the USB and is used as the USB device end. The muti _ fastboot communication realized by the u-boot end of the mobile terminal completely follows the standard fastboot protocol, and when the mobile terminal communicates with fastboot of the PC end, the PC end fastboot serves as a server end, and the muti _ fastboot of the u-boot end serves as a client end.
In the process of updating the flash, muti _ fastboot can support only one eMMC (for example, only eMMC 0 is operated, command: muti _ fastboot mmc 0), and can also support 2 emmcs at the same time, and in the process of specific flash, the number corresponding to the eMMC is automatically found according to the partition name, and then the corresponding eMMC is operated. Taking the u-boot end brush mode including eMMC 0 and eMMC 01 as an example, the command is exemplified as follows:
1. Single brushing machine eMMC 0
(1) U-boot end command:
muti_fastboot mmc 0
(2) PC side command:

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

fastboot erase{partition}
Examples of commands are 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 qnxdisk
fastboot erase product
fastboot erase userdata
Formatting:
Formatting a partition:
fastboot format{partition}
fastboot format userdata
global formatting, reestablishing the partition table:
fastboot oem format
It should be noted that for a system employing a/B partitioning, muti _ fastboot is only flushed to one partition in a/B, as the a/B partitioning is mainly used for OTA upgrades, etc., and this option may be set in the implementation of muti _ fastboot. That is, assuming that the system boot is set to use the A partition, when the PC side executes the command "fastboot FLASH SYSTEM system. Img" to flush, only the system_a partition is flushed, and the system_b partition is disregarded.
3. Automatic brushing machine according to subareas
1) U-boot end command:
muti_fastboot mmc
(2) PC side command:
And the PC end command is completely the same as the commands in the commands 1 and 2, after the commands are executed, the u-boot end automatically installs and transmits the past partition name to search the number of the eMMC, and then the corresponding eMMC partition is operated.
PC end fastboot public instruction
Loading kernel operation according to u-boot parameters:
fastboot boot
Restarting:
fastboot reboot
fastboot reboot bootloader
Reading version information:
fastboot getver:version
as known from the above upgrade of the communication brush machine matched with muti _ fastboot of the PC end fastboot and the u-boot end, the embodiment completely follows fastboot protocol standard, mainly performs unified management of synchronous operation on eMMC 0 and eMMC 1, and reduces the differentiation of use to the greatest extent, so that the use of users is simpler and more convenient.
