Background
In the embedded industry, the development and sample verification is successfully completed and then the mass production is shifted, and in consideration of different application environments of products, most of the products adopt NAND memories with wider requirements on temperature ranges to store firmware. In order to speed up the production of products, the products usually adopt a master burning mode to burn NAND memory firmware in batch in a factory stage. Because the NAND memory does not have corresponding data management and check-up function, has certain probability bad block moreover, leads to special tool can't satisfy the volume production, and the volume production instrument probably appears very big defective products rate.
Disclosure of Invention
The invention aims to solve the technical problem of providing a batch burning method suitable for an IMX6 series core board NAND, and solving the problem caused by processing NAND storage original factory bad block logic in a batch burning tool.
In order to achieve the purpose, the invention adopts the following technical scheme:
a batch burning method suitable for an IMX6 series core board NAND comprises the following steps:
step S1: and burning the welded master chip core board to a system which is finally delivered from a factory, and starting verification is not needed after burning.
The method comprises the steps that boot verification is not performed after a master chip core board is burnt, a YAFFS2 file system needs to check whether a check point exists in a NAND storage medium when the burnt core board is started for the first time, and the burnt NAND storage medium does not have the check point and relevant fingerprint information because the system is not started after burning is finished, so that batch burnt images are real factory-leaving images instead of clone images.
Step S2: the core plate is picked and the mirror image in the master is extracted using a batch tool.
Step S3: and optimizing the master image by using a master image processing tool and exporting a partition table.
The master slice image optimization processing tool is mainly used for calculating the absolute position, ECC (error correction code) check information and bad block identification of each partition image of the extracted master slice image through binary, slicing the master slice image, wherein the slicing granularity is determined according to the partition information and the original factory structure in the actual master slice image. And placing the sliced mirror image slices according to the processing logic of the Linux system, and exporting a partition table, so that subsequent batch tools can be conveniently imported.
Step S4: and leading the derived partition table and the derived mirror image set into a batch burning tool, and burning the partition table and the derived mirror image set into the NAND storage medium of the core board.
In the step, the batch burning tool is required to be configured to jump over the bad blocks when the bad blocks in the original factory are encountered, the bad blocks are erased before burning, and the bad blocks are removed after the bad blocks exceed the product quality threshold, so that the factory failure rate of the product is reduced by matching with the configuration derived in the second step.
Step S5: and verifying whether the core boards subjected to batch burning normally operate or not.
After the burning is successful, the system is welded on a core board to verify whether the system can normally operate or not, and mass production can be carried out after the system is error-free; and if the core board for batch burning cannot normally operate, erasing or eliminating the bad block, and returning to the step S1.
The core board is an IMX6 series core board.
Compared with the prior art, the batch burning method suitable for the NAND of the IMX6 series core board has the following beneficial effects:
the invention carries out optimization processing on the extracted master slice mirror image during production and then carries out batch programming, and because the optimization program avoids the interference of various problems of more system partitions, different partition formats, possible broken blocks of original factories and the like at any positions of different partitions in a core board, the problem that the program cannot run after batch programming occurs in the system during the actual production and manufacturing process does not occur any more. Different optimization schemes are selected in combination with actual firmware types, and the failure rate can be greatly reduced by burning the optimized configuration file.

Detailed Description
The technical solution of the present invention is further illustrated by the accompanying drawings and examples.
Example (b):
as shown in fig. 1, a batch burning method suitable for the NAND of IMX6 core boards includes the following steps:
step S1: burning the welded master core board to a system which is finally delivered from a factory, and starting up verification is not needed after burning;
step S2: picking up the core plate, and using a batch tool to pick up the mirror image in the master slice;
to extract the master image. Firstly, a welded core board is burnt to a system which finally leaves a factory, starting verification is not needed after burning, a YAFFS2 file system needs to check whether a check point exists in a NAND storage medium when the burnt system is started for the first time, and the burnt NAND storage medium does not have the check point and relevant fingerprint information because the system is not started after burning is finished, so that batch burnt mirror images are real factory-leaving mirror images instead of clone mirror images. The mirror image in the soldered master is extracted directly using a batch tool.
Step S3: optimizing the master image by using a master image processing tool and exporting a partition table;
the master mirroring process tool optimizes the mirroring. The master slice image optimization processing tool is mainly used for calculating the absolute position, ECC (error correction code) check information and bad block identification of each partition image of the extracted master slice image through binary, slicing the master slice image, wherein the slicing granularity is determined according to the partition information and the original factory structure in the actual master slice image. And placing the sliced mirror image slices according to the processing logic of the Linux system, and exporting a partition table, so that subsequent batch tools can be conveniently imported.
Step S4: leading the derived partition table and the derived mirror image set into a batch burning tool, and burning the partition table and the derived mirror image set into a NAND storage medium of the core board;
step S5: and verifying whether the core boards subjected to batch burning normally operate or not.
And importing the exported partition table and the exported mirror image set into a batch burning tool and finishing burning. In the step, the batch burning tool is required to be configured to jump over the bad blocks when the bad blocks in the original factory are encountered, the bad blocks are erased before burning, and the bad blocks are removed after the bad blocks exceed the product quality threshold, so that the factory failure rate of the product is reduced by matching with the configuration derived in the second step. After the burning is successful, the system is welded on a core board to verify whether the system can normally operate or not, and mass production can be carried out after the system is error-free; and if the batch burning core boards can not normally run, erasing or eliminating the bad blocks, and burning the master chip core boards again.
In the production operation process, firstly, a system (comprising u-boot. imx, zmimag, rootfs. tar. bz2, modules. tar. bz2, imx6 ul-S-sdrun-gpmi. dtb) on a core board is downloaded to a NAND storage medium on the core board through an SD card burning tool, and after burning is completed, a welding tool is used for extracting original data in the NAND storage medium into a bin file. And then, optimizing the extracted master program by using a master mirror image processing tool, reading the output file by a batch programming tool, and configuring and programming the output file into the NAND memory. And finally, the batch programmed NAND memory chips can be directly welded on the core board when the core board is manufactured and welded, so that the batch production is realized.
In addition to the technical features described in the specification, the technology is known to those skilled in the art.
