Detailed Description
The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art without making any creative effort with respect to the embodiments in the present application belong to the protection scope of the present application.
At present, the upgrading mode of the wireless communication module is to upgrade various different baseband chips and firmware memories (such as erasable nonvolatile memories, such as flash memories) provided by different chip manufacturers by using various different upgrading tools provided by different chip manufacturers. For example, the chip provided by the manufacturer a can only be upgraded by using the upgrade tool provided by the manufacturer a, and the chip provided by the manufacturer B can only be upgraded by using the upgrade tool provided by the manufacturer B, so that the upgrade tools at the research and development places or the customer places of the company are too dispersed and easily confused, and too many upgrade tools cause inconvenience in use. Therefore, an intensive and intelligent upgrading tool is needed for internal research and development teams and clients. Therefore, embodiments of the present application provide a module upgrading method, apparatus, medium, device, and program product to improve convenience of upgrading a wireless communication module.
Specifically, the module upgrading method provided by the embodiment of the application can be applied to computer equipment. Referring to fig. 1, the computer device may be equipped with a preset upgrade tool, and the computer device may be in communication connection with a module to be upgraded through a USB interface or a LAN interface, where the module to be upgraded may be installed in a device or an apparatus such as a communication device, a development board, a client, and the like, and then, the module type of the module to be upgraded may be identified according to a chip type in the module to be upgraded, and then, a target upgrade algorithm may be determined according to the module type of the module to be upgraded and a pre-stored upgrade algorithm list, and the upgrade algorithm list may include a plurality of module types corresponding to different chip types and a plurality of upgrade algorithms, and the plurality of module types and the plurality of upgrade algorithms have a one-to-one correspondence relationship.
The following are detailed below. It should be noted that the description sequence of the following embodiments is not intended to limit the priority sequence of the embodiments.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a module upgrading method according to an embodiment of the present application, where the module upgrading method is applied to a computer device, and the method mainly includes steps 101 to 103, which are described as follows:
and S101, performing communication connection with a module to be upgraded.
The computer device may be equipped with a preset upgrade tool, and the preset upgrade tool may be integrated with resource files provided by chip manufacturers, for example, the upgrade tool and the upgrade program provided by the chip manufacturers, so that the preset upgrade tool may upgrade the communication modules corresponding to the chips. The module to be upgraded is a wireless communication module. For example, the 3G module may be a Wideband Code Division Multiple Access (WCDMA) module or a time division-synchronous code division multiple access (TD-SCDMA) module. For example, the 4G module is a time division-synchronous code division multiple access (time division-synchronous code division multiple access) module.
Specifically, the computer device may be provided with a USB (universal serial bus) interface and/or a LAN (local area network) interface, and the module to be upgraded may be in communication connection with the preset upgrade tool through the USB interface or the LAN interface. Specifically, the module to be upgraded may be installed on a dedicated development board, and communicatively connected to the computer device, and then the computer device writes the new firmware into the firmware memory of the module to be upgraded through the interface using the target upgrade algorithm corresponding to the module to be upgraded, thereby upgrading the module to be upgraded. The USB interface can simulate a COM port and an ADB port. If the module to be upgraded uses the COM port simulated by the USB, the preset upgrading tool can call a target upgrading algorithm of the USBCOM port to upgrade the communication module. If the module to be upgraded uses the ADB port simulated by the USB, the preset upgrading tool can call a target upgrading algorithm of the ADB port to upgrade the module to be upgraded. If the module to be upgraded uses the LAN port, the preset upgrading tool can call a target upgrading algorithm of an interface of a TCP/IP protocol to upgrade the communication module.
It is easy to understand that the wireless communication module is usually applied to the client of the Linux system, and if the wireless communication module needs to be upgraded subsequently, for example, performance optimization or new functions are required to be optimized, the wireless communication module is mainly detached from the client of the Linux system and connected to the Windows system for upgrading, and if power is cut off, the radio frequency calibration information of the wireless communication is lost. Therefore, the existing upgrading mode is not only complicated, wastes time and labor, but also can cause damage to the wireless communication module, and the reliability is poor.
Therefore, the embodiment of the application can adopt the same code, compile a first upgrading tool on the WINDOWS system and a second upgrading tool on the LINUX system, and then integrate the first upgrading tool and the second upgrading tool through a cross-platform program. When the preset upgrading tool runs on the WINDOWS system, the first upgrading tool can be automatically called, and when the preset upgrading tool runs on the LINUX system, the second upgrading tool can be automatically called.
Specifically, the conventional module upgrading method usually only supports COM port connection simulated by a USB interface and usually only supports WINDOWS operating system, and the module upgrading method provided in the embodiment of the present application may support connection of COM and ADB modes enumerated by a USB interface and LAN interfaces, and may also support WINDOWS system and LINUX system. Therefore, the module upgrading method provided by the embodiment of the application can meet various requirements of upgrading the wireless communication module and is compatible with upgrading of the wireless communication module in various scenes.
In some embodiments, after the preset upgrading tool is in communication connection with the module to be upgraded, the user may be prompted that the connection is made. For example, the computer device may include an indicator light, and may prompt the user to preset that the upgrade tool is connected to the module to be upgraded in a manner of blinking the indicator light. For example, when the computer device runs a preset upgrade tool, a red light may be flashed to prompt the user that the current status is waiting for connection. For example, after the preset upgrading tool is in communication connection with the module to be upgraded, the green light can be turned on for a long time to prompt the user that the current state is to be upgraded.
Step S102, according to the chip type in the module to be upgraded, identifying the module type of the module to be upgraded.
It is easy to understand that different chip manufacturers provide different baseband chips, and different wireless communication modules employ different baseband chips, so that different wireless communication modules need to be upgraded by using upgrade algorithms provided by different chip manufacturers. Therefore, before the module to be upgraded is upgraded, first, the module type of the module to be upgraded should be identified.
Specifically, the computer device may be installed with a preset upgrade tool, and the preset upgrade tool may provide an interaction page, and step S102 may include: identifying the chip type corresponding to the upgrading task of the module to be upgraded according to the item name of the upgrading task of the module to be upgraded selected based on the interactive page, and determining the module type of the module to be upgraded according to the chip type corresponding to the upgrading task of the module to be upgraded.
For example, the baseband chip may be an NB-IOT baseband chip, a 2G baseband chip, a 3G baseband chip, or a 4G baseband chip.
In some embodiments, by operating the preset upgrade tool, the computer device may display an interactive page through which a user may select a project name of a module to be upgraded, and then the preset upgrade tool may determine a chip type used by the project according to the project name, thereby determining a module type of the module to be upgraded. And then, in the subsequent steps, determining a corresponding target upgrading algorithm according to the module type of the module to be upgraded, and upgrading the module to be upgraded according to the target upgrading algorithm.
Step S103, determining a target upgrading algorithm according to the module type of the module to be upgraded and a pre-stored upgrading algorithm list, and upgrading the module to be upgraded according to the target upgrading algorithm.
Specifically, an upgrade algorithm list may be stored in the preset upgrade tool, where the upgrade algorithm list may include a plurality of module types and a plurality of upgrade algorithms, and the plurality of module types and the plurality of upgrade algorithms have a one-to-one correspondence relationship. The step of determining a target upgrade algorithm according to the module type may include: and determining an upgrading algorithm corresponding to the module type of the module to be upgraded in the upgrading algorithm list as a target upgrading algorithm by matching the upgrading algorithm list in the preset upgrading tool.
For example, if the communication module is a 2G module installed with a 2G baseband chip, the upgrade algorithm corresponding to the 2G module is determined as the target upgrade algorithm. And then, upgrading the 2G module by adopting the target upgrading algorithm.
In some embodiments, when the module to be upgraded is upgraded, the user may be prompted by the indicator light. For example, a green light may be flashed to indicate to the user that the current status is being upgraded. Therefore, the upgrading process of the module to be upgraded is transparent, and a user can know the upgrading state conveniently.
In some embodiments, the method may further comprise: if the target upgrading algorithm corresponding to the module type of the module to be upgraded cannot be determined, sending the module type of the module to be upgraded to a server, and if the server stores the upgrading algorithm corresponding to the module type of the module to be upgraded, downloading the upgrading algorithm corresponding to the module type of the module to be upgraded and updating the upgrading algorithm list. And if the server does not have the upgrading algorithm corresponding to the module type of the module to be upgraded, prompting the user of upgrading failure and prompting the reason of the upgrading failure of the user.
Specifically, if a resource file provided by a certain chip manufacturer, such as an upgrade tool and an upgrade algorithm, is not integrated in the current preset upgrade tool, the corresponding upgrade tool and upgrade algorithm may be downloaded from the server, and the corresponding upgrade tool and upgrade algorithm may be integrated in the preset upgrade tool, so that the types of upgrade algorithms in the preset upgrade tool are richer, and the upgrade of more wireless communication modules may be completed. If the server does not have the corresponding upgrading tool and upgrading algorithm, prompting the user of upgrading failure and prompting the reason of the user failure, so that the subsequent processing of the user is facilitated. For example, a prompt dialog box may be displayed to prompt a user that the upgrade fails, and the reason for the failure is that there is no upgrade algorithm corresponding to the module type, so that the user may take subsequent operations according to the prompt dialog box.
In some embodiments, the method may further comprise: when a preset upgrading tool in computer equipment is initialized, reading the version of the preset upgrading tool in the computer equipment, and acquiring the version of the preset upgrading tool in a server; if the version of the preset upgrading tool in the server is higher than that of the preset upgrading tool in the computer equipment, first prompt information for prompting a user to update the preset upgrading tool in the computer equipment is generated.
The first prompt message may be a text message or a voice message or both. For example, a prompt dialog may be displayed and prompt text may be displayed via the prompt dialog. Alternatively, the alert sound may be played through a speaker. Alternatively, the prompt sound may be played through a speaker and the prompt text may be displayed through a display prompt dialog.
It is easy to understand that, when each chip manufacturer provides an updated resource file, the server may update the resource file saved in the preset upgrade tool, and may identify the version of the preset upgrade tool by using the version number. Then, when the preset upgrading tool in the computer device is initialized, the version of the preset upgrading tool on the server can be read, and if the version of the preset upgrading tool on the server is higher than that of the preset upgrading tool in the computer device, a user is prompted that the version of the preset upgrading tool is updated.
Specifically, the version of the preset upgrade tool may be identified digitally. For example, the version number of the preset upgrade tool of the initial version is 1.0, and the version number of the remaining upgrade tool after one update is 1.1. For example, when a user starts a preset upgrade tool on a computer device and the preset tool is initialized, the version number of the preset upgrade tool in the computer device may be read, and the version number of the preset upgrade tool in the server may be obtained at the same time, and if the version number of the preset upgrade tool in the computer device is 1.0 and the version number of the preset upgrade tool in the server is 1.1, the user is prompted that the version of the preset upgrade tool is updated.
In this embodiment, the method may further include: and if an updating instruction aiming at the preset upgrading tool in the computer equipment is received, updating the preset upgrading tool in the computer equipment.
Specifically, the user may be prompted by displaying a prompt dialog box to indicate that the version of the upgrade tool is updated. The prompt dialog box may be provided with a selection area, the selection area may display an update button, and a user may update a preset upgrade tool in the computer device through a selection operation for the update button. Specifically, if the user selects to update the preset upgrade tool in the computer device, an update instruction for the preset upgrade tool is generated, and the preset upgrade tool with a higher version is downloaded from the server, so as to update the preset upgrade tool in the computer device.
In some embodiments, the method may further comprise: if the module to be upgraded fails to be upgraded, determining a failure reason; if the failure reason indicates that the module to be upgraded has errors, generating second prompt information for prompting the user of upgrading failure; and if the failure reason indicates that the target upgrading algorithm is wrong, downloading the target upgrading algorithm again from the server, and upgrading the module to be upgraded again according to the downloaded target upgrading algorithm.
Wherein, the second prompt message can be text message or voice message or both. For example, a prompt dialog may be displayed and prompt text may be displayed via the prompt dialog. Alternatively, the alert sound may be played through a speaker. Alternatively, the prompt sound may be played through a speaker and the prompt text may be displayed through a display prompt dialog.
It is easy to understand that, in order to avoid the upgrade error of the wireless communication module and cause the problem of the subsequent use, the preset upgrade tool can automatically judge whether the upgrade is completed. For example, the preset upgrade tool may determine whether the firmware in the firmware storage area of the module to be upgraded is complete and consistent with the upgraded firmware, so as to enable a user to determine whether the upgrade is completed. If the firmware in the firmware storage area of the module to be upgraded is complete and consistent with the upgraded firmware, judging that the upgrade is completed, and prompting the user that the upgrade is successful. If the firmware in the firmware storage area of the module to be upgraded is incomplete or inconsistent with the upgraded firmware, judging that the upgrade fails and determining the reason of the failure. And if the failure reason indicates that the module to be upgraded makes mistakes, prompting the user that the upgrading fails and ending the upgrading. And if the failure reason indicates that the target upgrading algorithm is wrong, downloading the target upgrading algorithm again from the server, and then upgrading the module to be upgraded again according to the downloaded target upgrading algorithm. Specifically, if the upgrade fails again, the user is prompted that the upgrade fails.
Specifically, the user may be prompted to fail to upgrade by flashing an indicator light, for example, flashing a red light at a high frequency.
Specifically, the failure reason may be determined by determining whether the upgrade firmware in the preset upgrade tool is complete or by determining that a target upgrade algorithm in the preset upgrade tool is consistent with a target upgrade algorithm in the server. If the upgrade firmware in the preset upgrade tool is incomplete, or the target upgrade algorithm in the preset upgrade tool is inconsistent with the target upgrade algorithm in the server, the failure reason can be determined to be that the target upgrade algorithm is wrong. Otherwise, it may be determined that the module to be upgraded is faulty.
It is noted that, in order to avoid the malfunction of the wireless communication module caused by the failed upgrade, the firmware in the firmware storage area may be backed up before the upgrade. After the upgrade fails, the firmware of the north backup is written into the firmware storage area, so that the usability of the wireless communication module can be ensured.
In some embodiments, the module to be upgraded may be installed in a terminal device, such as a smart phone, a smart watch, or the like, and the module to be upgraded is in communication connection with the computer device through the terminal device. In order to avoid the upgrade failure caused by the power failure of the terminal device, the method may further include: detecting the electric quantity of the terminal equipment; and if the electric quantity of the terminal equipment is smaller than the lowest threshold value, supplying power to the terminal equipment.
The minimum threshold is generally a value determined in consideration of the minimum electric quantity before the terminal device is powered off, for example, the maximum electric quantity of the terminal device is one hundred, and when the electric quantity of the terminal device is zero, the terminal device is powered off, the minimum threshold may be one, which is not limited in this application. For example, the terminal device is in communication connection with the computer device through the USB interface, and when the computer device detects that the electric quantity of the terminal device is less than five percent, power is supplied to the terminal device, so that upgrading failure caused by shutdown of the terminal device is avoided.
For better explaining the module upgrading method provided in the embodiment of the present application, please refer to fig. 3, where the module upgrading method provided in the embodiment is applied to a computer device, the computer device is installed with a preset upgrading tool, and the module upgrading method can be summarized as the following steps:
step 201, starting a preset upgrading tool.
Step 202, when the preset upgrade tool is initialized, reading the version of the preset upgrade tool in the computer device, and obtaining the version of the preset upgrade tool in the server.
Step 203, if the version of the preset upgrade tool in the server is higher than the version of the preset upgrade tool in the computer device, generating first prompt information for prompting the user to update the preset upgrade tool in the computer device.
Step 204, if an update instruction for a preset upgrade tool in the computer device is received, downloading the preset upgrade tool from the server.
And step 205, connecting with the module to be upgraded in a communication way.
And step 206, determining the module type of the module to be upgraded according to the chip type in the module to be upgraded.
Step 207, determining an upgrading algorithm corresponding to the module type of the module to be upgraded in the pre-stored upgrading algorithm list as a target upgrading algorithm, and upgrading the module to be upgraded according to the target upgrading algorithm.
The upgrading algorithm list comprises a plurality of module types and a plurality of upgrading algorithms corresponding to different chip types, and the module types and the upgrading algorithms have one-to-one correspondence.
208, if the module to be upgraded fails to be upgraded, determining the reason of the failure

And step 210, if the module to be upgraded is successfully upgraded, generating third prompt information for prompting the user that the upgrading is completed.
Wherein, the third prompt message can be a text message or a voice message or both. For example, a prompt dialog may be displayed and prompt text may be displayed via the prompt dialog. Alternatively, the alert sound may be played through a speaker. Alternatively, the prompt sound may be played through a speaker and the prompt text may be displayed through a display prompt dialog.
