Detailed Description

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict.

Referring to fig. 1 to 5, the functional implementation of the present invention includes: and (3) automatically entering an upgrading command by pressing a RESET key on the uboot, embedding a tftp server in the uboot, detecting the type of the firmware and automatically operating. During upgrading, an operator presses a RESET key by using a special tool to power on, the router automatically enters a background command line, and then after relevant mac and sn information is scanned, the whole process is automatically completed by automatic operation software.

the system receives the upgrade file and carries out upgrade operation;

The tftp server is embedded in the router in advance.

The content of the request file includes a file type, a checksum, and a data portion. The file type is used to define the particular firmware portion to which the router is to be upgraded. And after the file uploading is finished, the uboot judgment system upgrades the file to a specific part of the flash.

Specifically, the uboot power-on holds the RESET key auto-entry command:

the firmware composition of the home wireless router is shown in fig. 1. When the wireless router is started, the system firstly enters uboot, and after the relevant peripheral time sequence is set, the relevant control right is handed to the kernel. The uboot is equivalent to a small starting system, the upgrading firmware is composed of a kernel and a file system, and the kernel is switched after the uboot is started. When the system enters the boot upgrading, a special key needs to be knocked in the serial port to enter the boot at the corresponding stage of the system, and meanwhile, the related serial port line needs to be accessed. The method replaces complex operation, saves cost and time and is very convenient and fast.

The invention utilizes the common RESET button of the household wireless router, referring to fig. 2, when the household wireless router is powered on, the corresponding key is pressed for 10 seconds, and then the uboot is entered to execute the relevant operation. The design does not need special serial port connecting wires and special commands, can be implemented by only pressing one key, and effectively reduces the operation difficulty of production line operators. Meanwhile, the design does not need to be opened, can be operated for many times, and eliminates defective products caused by secondary opening. The RESET key has corresponding restart definition in a kernel stage, and has no restart significance in uboot, so that the problem of key conflict does not exist.

uboot embeds tftp server:

existing designs routinely erect tftp servers on PCs that are connected to wireless home routers when upgrading. Therefore, when upgrading operation is carried out, the domestic wireless router sends an estrus file to the pc, and tftp server service software needs to be additionally built on the pc. For operators on site, the operation difficulty is inevitably increased by such operation, and the operation difficulty of workers is increased.

Referring to fig. 3, the invention converts the file request mode, and embeds a tftp server service software in the home wireless router. This changes from the way the wireless router had to make a request to the PC before to the way the PC actively makes a request to the home wireless router. The PC can be changed from a server role to a client role, full-automatic control can be achieved through control of an automatic calibration program, and operation difficulty of a production line is further simplified.

Referring to fig. 4, the composition of the file is composed of a file type, a checksum, and a data part.

The file type is an upgrade file type, and the section defines which section of the firmware of the home wireless router the tftp uploaded file is to be upgraded. After the file is uploaded, the uboot judges which part of the flash the file needs to be upgraded to according to the definition of the part. The checksum part is the checksum of the data part and can be used and checked commonly, the data integrity is guaranteed, and the condition that the upgrading fails due to data uploading errors is prevented.

Referring to fig. 5, the automation includes two parts, an automated operation tool and automated operation software. The automatic tool is required to manufacture a piece of production furniture, and after a household wireless router is installed in the tool, the RESER key is propped by a special part, so that the purpose of pressing the RESER key to electrify is achieved. The purpose of the automation software is to replace the traditional manual operation mode and to be automatically executed by the automation software, so that the efficiency is further improved, and the productivity is liberated. The automation tool is deployed on a PC connected to a home wireless router.

The method comprises the following steps: the system enters mac and sn information through scanning. And after the system detects that the network connection with the wireless router is successful, uploading the upgrade file. And when the system detects that the upgrading is finished, the system quits the upgrading operation.

The scheme has the following advantages:

1) without requiring a tear down upgrade

When the household router factory in the prior art is upgraded, the command line is usually upgraded after entering a background command line and inputting a user name and a password, so that the upgrading efficiency is greatly limited. Especially, the model of good packing or reprocess does not often take serial ports connector, must unpack and carry out relevant operation with the thimble, and complex operation is consuming time, also can bring the secondary defective products simultaneously. Aiming at the situation, the invention automatically enters the uboot background for upgrading by pressing the RESET key 10S carried by the household router when the household router is powered on.

2) Simple environment construction

When a factory is upgraded in the past, a tftp server is generally required to be built at an operation station, and a serial port line is additionally arranged for operation. The invention improves the upgrading environment, the tftp server is built in the uboot of the household wireless router, and the lan port of the household wireless router and the pc are connected by only one network wire during upgrading operation, so that the upgrading can be carried out through the pc without more operations.

3) High automation degree

In order to further reduce the operation difficulty of workers, the invention designs automatic station operation software, after the wireless router is started, only a network cable is plugged, and after the mac and the sn of the wireless router are automatically scanned by a scanning gun, a series of related actions can be automatically completed by the operation software, so that the operation difficulty of the workers is further reduced.

4) High reliability and repeated operation

In the past, when a product is upgraded, if one-time operation upgrading fails, a system crashes; if the repair is needed, related uncovering work is needed. Because the tftp server is embedded in the uboot, the firmware can be repeatedly operated after the upgrade failure, and certain reliability and repeated operability are achieved; the design mainly aims at the problem of the brick machine caused by upgrading failure, and the uncontrollable property is thoroughly eliminated.

While the preferred embodiments of the present invention have been illustrated and described, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
