Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to a method, device, equipment and computer-readable storage medium for logical backup and formatted downloading of device parameters. Background Art

[0002] When upgrading the software of the machine, the existing MTK download tool will compare the software partition address in the machine with the partition address of the software to be upgraded. If the partition address used to store parameters is changed, each partition storing parameters will be physically backed up. After all partitions are backed up locally according to the partition address, formatting and downloading will be performed. After the download is completed, the parameter files stored locally will be restored to the machine according to the partition address. If the partition address storing parameters has not changed, the backup operation will not be performed and the formatting of the relevant partitions will be skipped, so as to ensure that the machine parameters will not be lost.

[0003] When handling faulty machines with lost parameters after sales, the UpdateParameter Tool in the modem_meta tool of mtk is used to perform a logical backup of the parameters in the machines of the same batch, save the parameters locally, and then rewrite the backup parameters to the faulty machine, thereby repairing the faulty machine that has lost parameters after using the download tool to upgrade the software.

[0004] The current download tool uses physical backup as the parameter backup solution when upgrading the firmware. However, when using the physical backup solution, some machines will inevitably lose parameters. In addition, it is necessary to ensure that the software partition address in the machine is highly consistent with the partition address of the upgraded software. When there is a difference in the software partition address, the probability of parameter loss will be greatly increased.

[0005] For machines that have lost parameters, the only way is to export the parameters from the same batch of machines and then import them back to the faulty machine. This operation is tedious and time-consuming, and requires engineers with relevant knowledge to operate correctly, which seriously affects production efficiency and quality control.

[0046] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0047] The device parameter logic backup and formatted download method involved in the embodiment of the present invention is mainly applied to computer equipment, which can be a PC, a portable computer, a mobile terminal or other equipment with display and processing functions.

[0048] Reference Figure 1 , Figure 1 Schematic diagram of the hardware structure of the computer device involved in the embodiment of the present invention. In the embodiment of the present invention, the computer device may include a processor 1001 (such as a CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. Among them, the communication bus 1002 is used to realize the connection and communication between these components; the user interface 1003 may include a display screen (Display), an input unit such as a keyboard (Keyboard); the network interface 1004 may optionally include a standard wired interface, a wireless interface (such as a WI-FI interface); the memory 1005 may be a high-speed RAM memory, or a stable memory (non-volatile memory), such as a disk memory, and the memory 1005 may optionally be a storage device independent of the aforementioned processor 1001.

[0049] Those skilled in the art will understand that Figure 1The hardware structure shown in the figure does not constitute a limitation on the computer device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0050] Continue to refer to Figure 1 , Figure 1 The memory 1005 as a computer-readable storage medium may include an operating system, a network communication module, and a device parameter logic backup and formatting download program.

[0051] exist Figure 1 In the embodiment, the network communication module is mainly used to connect to the server and perform data communication with the server; and the processor 1001 can call the device parameter logic backup and formatting download program stored in the memory 1005, and execute the device parameter logic backup and formatting download method provided in the embodiment of the present invention.

[0052] The embodiment of the present invention provides a method for logical backup and formatted downloading of device parameters.

[0053] Reference Figure 2 , Figure 2 It is a flowchart of the first embodiment of the device parameter logic backup and formatted download method of the present invention.

[0054] In this embodiment, the device parameter logical backup and formatted download method includes the following steps:

[0055] Step S10, when the target device enters the test mode, based on the first interface of the database, reading the database file of the target software in the target device;

[0056] In this embodiment, when the parameters of the target device need to be backed up, the target device is connected via a computer or other computer device, and when the target device enters a test (meta) mode, the database file in the target device is read by calling a database interface.

[0057] In one embodiment, the target device may be an electronic product such as a mobile phone or a tablet computer.

[0058] In one embodiment, the target device enters the test mode, comprising: based on the download instruction, calling the third interface of the database, so that the target device is initialized to enter the test mode.

[0059] In one embodiment, the third interface includes:

[0060] META_RESULT METACONNAPI MetaConn_Connect(const char*,void*para,METACONN_RESULT*output_para).

[0061] In one embodiment, after the download tool clicks download, the tool enters a state of waiting for device insertion, and waits for the device to be initialized and enter meta mode by calling the first interface in the mtk interface library MetaApp.dll.

[0062] In one embodiment, the MTK platform is a widely used chip platform, mainly used in mobile devices such as smart phones and tablet computers.

[0063] In one embodiment, the first interface may include:

[0064] META_RESULT METACONNAPI MetaConn_GetTargetNvDatabaseFile(int handle,wchar_t*file_name,bool*isGetFile).

[0065] In one embodiment, the meta mode is a test mode used by the MTK platform for calibration and coding. Unlike direct boot, it requires many services to be enabled (such as timers, queues, memory management, and events, etc.), and the NV area cannot be directly read or written. The meta mode contains many interfaces that can be called by the PC software to read and edit the NV area where the parameters are stored.

[0066] Step S20, based on the second interface in the database and the database file, read and write the frequency band related parameters corresponding to each frequency band in the target device to obtain a backup file, so as to realize parameter backup of the target device;

[0067] In one embodiment, after successfully entering the mode, the second interface in the mtk interface library MetaApp.dll is called to obtain the database file of the software (hereinafter referred to as the db file) from the mainboard. The database file can be obtained not only by entering meta, but also in the software released by R&D, or directly exported from the mobile phone when the phone is turned on.

[0068] It can be understood that the database file is a necessary file for reading and writing parameters, and there is also a corresponding interface for obtaining the database in meta mode, so here we directly call the interface to obtain the database file after entering meta mode. After successfully obtaining the db file in the device and saving it locally, you can start reading and writing parameters.

[0069] Furthermore, if Figure 3 As shown, the step S20 specifically includes:

[0070] Step S21, based on the second interface, reading frequency band related parameters corresponding to each frequency band in the database file;

[0071] Step S22: based on the character string type saving format, write the frequency band related parameters corresponding to each frequency band into the initialization file for saving, and obtain the backup file.

[0072] In one embodiment, the second interface is a data interface corresponding to at least one of the frequency band related parameters.

[0073] In one embodiment, when the device enters the meta mode and successfully obtains the db file, the parameters corresponding to each frequency band are obtained by calling each frequency band related parameter interface in the mtk interface library MetaCore.dll.

[0074] In one embodiment, the frequency band related parameters are classified into general items, including GSM items, TDSCDMA items, WCDMA items, LTE items, C2K items, and NR items.

[0075] Among them, General Item represents the general / general category, including IMEI, Barcode, GPS Co-Clock, MultiRat Tadc, MMRF AFC, FR1 Self-Calibration, FR2Self-Calibration, and Error GeneralCal data.

[0076] Among them, GSM (Global System for Mobile Communications) is a digital mobile communication standard developed by the European Telecommunications Standards Organization ETSI. Its air interface adopts time division multiple access technology. GSM includes AFC, DCXO LPM, RX Path Loss, W Coefficient, GMSK Level, Ramp, EPSK Level, Ramp, Gain RF, Interslot, GMSK, Open loop TXPC, EPSK, Open loop TXPC, TemperatureADC, Self Cal, TX Rollback, and Error Gsm Cal data.

[0077] Among them, TDSCDMA (Time Division-Synchronous Code Division Multiple Access) includes AFC, RX Tath Loss, TPC, Temperature ADC, Self Cal, and ErrorTdscdma Cal data.

[0078] Among them, WCDMA (Wideband Code Division Multiple Access) includes AFC, RX Path Loss, RX Diversity Path Loss, TPC, PA Drift Compensation, PRACH TxTemperature Compensation, Temperature ADC, Self Cal, DPD, Mipi TPA Profile, and ErrorWcdma Cal data.

[0079] Among them, LTE (Long Term Evolution) includes AFC, RX Path Loss, POC, TPC, ET, DPD, DPD PA Profile, CIM3, Temperature ADC, Self Cal, Mipi PA, Max PA Input, and Error LTE Cal data.

[0080] Among them, C2K (Code Division Multiple Access 2000) includes AFC, RXPath Loss, Rx Diversity Path Loss, TPC, DPD Profile, Temperature ADC, Self Cal, MEID, MIPI, and Error C2K Cal data.

[0081] Among them, NR (New Radio) includes RX Path Loss, APT Profile, DPD, FR2 DPD, ET, SRS, Max PA Input, and Error General Cal data.

[0082] In one embodiment, the second interface may include:

[0083] META_RESULT__stdcall META_ERf_GetAfcSetting_r(const int meta_handle,const unsigned int ms_timeout,ERfFreqAdjustTable*resp);

[0084] META_RESULT__stdcall META_ERf_GetRxTxSetting_r(const int meta_handle,const ERfTestCmdGetRxTxSettingReqParam_T*req,const unsigned int ms_timeout,ERfTestCmdRxTxSetting*resp).

[0085] In one embodiment, all parameters can be read out by traversing each content in NVRAM (Non-Volatile Random Access Memory) and calling the library interface.

[0086] Furthermore, if Figure 4 As shown, the step S22 specifically further includes:

[0087] Step S23, based on the character string type corresponding to the frequency band related parameters, write the frequency band related parameters corresponding to each frequency band into the initialization file, and save them according to the node, key, and value distinction to obtain the backup file.

[0088] In one embodiment, if Figure 5 As shown in the figure, the parameters read from the device are saved and written into the ini file using the string type, and are stored separately by node, key, and value. At the same time, the ini file is named with the unique chip id of the baseband chip, so as to distinguish the corresponding parameters of different device motherboards.

[0089] In one embodiment, nodes, keys, and values ​​are fixed formats of the ini file. At the same time, such storage can clearly distinguish different parameters of different frequency bands, which is conducive to subsequent matching and rewriting.

[0090] In one embodiment, the chip ID of the baseband chip can be obtained by calling the interface in the mtk library file MetaCore.dll:

[0091] META_RESULT__stdcall META_MISC_GetRID_r(const int meta_handle,constunsigned int ms_timeout,unsigned char*u1Rid,const unsigned int ui_RidLen).

[0092] Step S30, when the target device exits the test mode, formatting and downloading the target software to the target device based on the preload port of the target device;

[0093] In this embodiment, after all parameters are backed up and saved locally, the connection is disconnected by calling the interface in the mtk library file MetaApp.dll to exit the test mode.

[0094] In one embodiment, the interface for exiting the test mode includes:

[0095] META_RESULT METACONNAPI MetaConn_Disconnect(int handle,void*para).

[0096] In one embodiment, if Figure 6 As shown, the step S30 specifically includes:

[0097] Step S31, executing a format download instruction based on the preload port;

[0098] Step S32, based on the format download instruction, erasing the historical storage data in the memory of the target device;

[0099] Step S33, after the historical storage data in the memory is erased, the data of the target software is downloaded and saved in the memory to complete the operation of downloading the target software to the target device.

[0100] In one embodiment, the device remains connected to the computer. After exiting the meta mode and shutting down, the computer will automatically read the preloader port of the device. After the download tool reads the port, the software can be formatted and downloaded. The formatting download process is to first erase the flash in the device and then download the software to the device.

[0101] In one embodiment, it is first necessary to clarify that system image files such as preloader, lk, kernel, and android are stored in nand flash, and each mtk chip has a boot rom. Figure 7As shown, at power-on time, the boot rom starts to start, and the boot rom loads the preloader into the internal SRAM. First of all, it should be clear that the system image files such as preloader, lk, kernel, and android are stored in the nand flash. Then each mtk chip has a boot rom. At power-on time, the boot rom starts to start, and the boot rom loads the preloader into the internal SRAM.

[0102] It can be understood that the preloader has a download function in addition to the boot function. First of all, it should be made clear that the MTK chip has a boot ROM. If there is no ROM, the program cannot be downloaded to the nandflash, and then the flash is empty without any data.

[0103] In one embodiment, after the system is powered on, it will detect whether it is in boot mode or download mode. If it is in download mode, it will initialize a USB serial port, load the preloader into the internal SRAM, jump to the preloader to execute, and after initializing the flash and external RAM, download the preloader, lk, kernel, and android to nand flash in sequence. Figure 8 shown.

[0104] Step S40, when the format download of the target software is completed and the target device enters the test mode, reading the database file based on the first interface of the database;

[0105] Step S50, based on the data path file, read the backup file, write the frequency band related parameters corresponding to each frequency band into the target device, so as to complete the parameter restoration of the target device.

[0106] In one embodiment, after the software download is completed, the device remains connected to the computer, and the computer automatically recognizes the port when power is off. At the same time, the device enters meta mode and obtains the db file by calling the interface in the mtk library file MetaApp.dll, just like the backup operation.

[0107] In one embodiment, after the device enters the meta mode and successfully obtains the db file, the ini file named by the corresponding baseband chip chip id saved locally is read, and the corresponding data and parameters in the ini file are restored to the device by calling each frequency band related parameter interface in the mtk library file MetaCore.dll. By traversing each content in each NVRAM and calling the library interface, all parameters can be rewritten.

[0108] The called interface is as follows:

[0109] META_RESULT__stdcall META_ERf_SetAfcSetting_r(const int meta_handle,const ERfFreqAdjustTable*req,const unsigned int ms_timeout);

[0110] META_RESULT__stdcall META_ERf_SetRxTxSetting(const bool update_to_nvram,const ERfTestCmdRxTxSetting*req,const unsigned int ms_timeout,ERfTestResultSetRxTxSettingCnfParam_T*resp).

[0111] Furthermore, when the parameter restoration of the target device fails, failure reminder information is generated to remind the user to check the firmware of the target device.

[0112] In one embodiment, since the software is formatted and flashed into the mobile phone, and each mobile phone firmware will be confirmed by R&D to see if there are any problems before release, the possibility of being unable to restore parameters after flashing is extremely low. If the restoration of parameters fails, the R&D personnel who output the software need to check the firmware they release.

[0113] In one embodiment, after traversing all parameters and writing the parameters to the device, the interface in the mtk library file MetaApp.dll can be called to disconnect and exit the meta mode, and the entire backup, formatting, upgrading, downloading, and restoring process is completed.

[0114] Understandably, in the prior art, when backing up device data and downloading software, it is necessary to switch tools before downloading, first use the modem_meta tool of mtk to connect the device, then select the UpdateParameter Tool in the meta tool, read the parameters in the device and save them locally, and then use the flashtool tool of mtk to download, and after the download is completed, it is necessary to switch back to the modem_meta tool, and use the UpdateParameter Tool tool to restore the backup parameter file saved locally back to the device. Switching back and forth between the two tools is very cumbersome.

[0115] In this embodiment, the device parameter logical backup and formatted download method can realize one-stop completion of logical backup parameters, formatted download, and logical restore backup operations, that is, the entire operation can be completed using only one tool, so that the operation process of backup and formatted download is simplified, and no engineers with relevant knowledge reserves are required to operate.

[0116] For example, during the project debugging stage, it is often necessary to format the phone to download the software, but the parameters in the phone need to be retained. At this time, you can use this tool to complete the operation in one stop, and achieve the desired effect simply and conveniently.

[0117] Or, when the baseband version number cannot be recognized after the mobile phone upgrades the software (that is, the software reads the db file abnormally), the parameters still exist, but because the baseband version cannot be recognized, the system reads the parameters in the NVRAM abnormally, resulting in problems with the device's functions related to parameters such as making calls and surfing the Internet. In this case, you can use this tool to complete the backup parameters and format and download operations in one stop to fix the device problem.

[0118] Alternatively, when using it during factory equipment upgrades, although the download time will be extended, the possibility of parameter loss will be greatly reduced, and a large amount of manpower will be avoided to repair equipment that loses parameters during the download process.

[0119] The embodiment of the present application provides a device parameter logical backup and formatted download method, which, when the target device is in the test mode, reads the database file by calling the first interface of the database, and saves the frequency band related parameters of the target device locally according to the second interface of the database and the database file to prevent data loss. Then, when the target device exits the test mode, the target software is formatted and downloaded, and after the formatted download is completed, the device parameters saved locally are completely restored to the target device, which can ensure the data integrity of the target device and avoid data loss. By logically backing up the parameters in the target device before formatting and downloading, and logically restoring the corresponding parameters after formatting and downloading, the possibility of machine parameter loss is reduced, and the entire operation process is simplified. The download of the system software and the backup of the system parameters in the target device are implemented in the same PC software, so that the download software of the target device and the backup and import of the RF parameters in the mobile phone can be completed at one time, simplifying the factory process for software upgrades across major versions to improve production efficiency, and solving the current technical problem of low efficiency in device parameter backup and import.

[0120] In addition, an embodiment of the present invention also provides a device parameter logic backup and format downloading apparatus.
