The embodiment of the invention provides a method for manufacturing a burning mirror image, which comprises the following steps:
and step 1, manufacturing an original mirror image file.
In this embodiment, the step 1 includes:
and step 101, compiling the target source program to generate an original image file of each partition.
The number of the original image files of each partition is the same as the number of the partitions of the data area in the partition table, for example, 12 partitions exist in the data area in the partition table, and then the number of the original image files of each partition is also 12. As an example, the original image file for each partition is named as follows: file1.bin, file2.bin, … File12.bin correspond to partition 1, partition 2 … …, partition 12, respectively, in the partition table.
As shown in fig. 2, in this embodiment, the first 12 partitions of the partition table are system data partitions, the 13 th partition is an application partition, and the 14 th partition is a user data partition.
And 102, splicing the original image files of all the partitions into a main image file according to the sequence of the partition table.
And step 103, calculating a first CRC code according to the main body mirror image file.
And 104, calculating a second CRC code according to the file identification, the length and offset address of the original image file of each partition and the first CRC code.
The file identifier is used for verifying the validity of the upgrade file corresponding to the target image file, for example, the file identifier is set as TBOX, then only the upgrade file identified as TBOX is legal, the upgrade operation is allowed to be executed, otherwise, the system considers that the upgrade file is illegal, and the upgrade operation is refused to be executed.
And 105, splicing the file identifier, the length and offset address of the original image file of each partition, the first CRC check code and the second CRC check code into a file header.
And 106, splicing the file header and the main body image file into an original image file.

And step 2, copying the original image file into storage equipment.
The storage device comprises a U disk, an SD card, a TF card, a mobile hard disk and the like.
And step 3, connecting the storage equipment with a target upgrading board, and burning the original mirror image.
The original program of the target upgrading board comprises the same U-BOOT as that in the original image.
In this embodiment, the step 3 includes:
step 301, detecting whether the original image file exists in the storage device by the U-boot of the target upgrading board, if yes, entering the next step, otherwise, exiting the upgrading;
step 302, analyzing the file header, obtaining the file identifier, judging whether the file identifier is legal, if yes, entering the next step, otherwise, exiting the upgrading;
step 303, calculating a third CRC check code of the file identifier, the length of each partition mirror image and the offset address, and judging whether the third CRC check code is identical to the second CRC check code, if yes, entering the next step, otherwise, exiting the upgrading;
step 304, calculating a fourth CRC check code of the main body mirror image file, judging whether the fourth CRC check code is the same as the first CRC check code, if so, entering the next step, otherwise, exiting the upgrading;
