Currently, in order to improve the cruising ability of the headset, a wireless headset charging box is generally equipped. In the production and repair process, the upgrading mode of the program firmware of the wireless earphone charging box is generally as follows: the charging box firmware program updating is to perform program firmware updating on a Microcontroller (MCU) on a Printed Circuit Board Assembly (PCBA) by adopting a special firmware burning tool and software on the PCBA.

Upgrading the firmware of the MCU microcontroller 120 in the conventional wireless headset charging box 100 is achieved through the proprietary update interface 160, which requires upgrading the firmware through computer software using a proprietary MCU burning tool.
Based on this, the embodiment of the application provides a program firmware upgrading method, device, electronic device and storage medium, which can overcome the defects brought by the traditional method of upgrading the program firmware of the MCU microcontroller on the PCBA by using a special firmware burning tool and software, improve the upgrading efficiency, and reduce the cost.

A power supply path is also arranged between the charging interface 110 and the power supply module 130, and the charging interface 110 provides working power supply for the power supply module 130 after charging. The communication data PIN of the charging interface 110 is connected with the PIN of the MCU microcontroller 120, a communication path is arranged between the MCU microcontroller 120 and the charging interface 110, and the two modules can communicate with each other. Compared with the structure of the conventional wireless earphone charging box 100, the wireless earphone charging box 100 provided by the embodiment of the application changes the firmware updating by adopting the special interface into the firmware updating by adopting the original charging interface 110 of the wireless earphone charging box 100, so that the structure of the wireless earphone charging box 100 is simpler. The charging interface 110 may obtain the upgraded firmware program transmitted from the firmware device 200, transmit the upgraded firmware program to the MCU microcontroller 120, verify the upgraded firmware program, and finally upgrade the firmware by the MCU microcontroller 120. The embodiment of updating the MCU firmware using the exposed charging interface 110 may not only be used to change the housing of the wireless headset charging box 100, but also be used to upgrade the firmware of the wireless headset charging box 100. Compared with the traditional special firmware programming tool and software for upgrading the program and firmware of the MCU 120 on the PCBA, the wireless earphone charging box 100 and the firmware device 200 are connected only by the embodiment of the application, and the firmware upgrading is waited to be completed.

The EEPROM supports byte erasure, has long period and can modify data in the running process. FLASH is a broad-sense EEPROM, and is called FLASH in order to distinguish it from a general EEPROM that is erased and written in units of bytes. The FLASH has low power consumption, supports byte erasure and is convenient to modify data. Some MCUs have no program memory, and executable codes can only be placed in external EEPROM and FLASH. In addition, the MCU can be used for storing some parameters, and storing some data which needs to be stored after power failure. The biggest difference between EEPROM and FLASH is that the former operates according to sector and the latter operates according to byte, the addressing modes of the two are different, and the structures of the memory cells are also different. EEPROM is used more as a non-volatile data memory and FLASH is suitable for use as a program memory. In the application, the MCU is designed and integrated with two nonvolatile memories, namely FLASH and EEPROM, and the advantages of the FLASH and EEPROM are combined, so that the firmware program can be better stored and upgraded. It is noted that in some embodiments, the memory devices of firmware memory module 220 include not only EEPROM, FLASH, and MCU. Those skilled in the art can select the storage device of the firmware memory module 220 according to actual situations, and will not be described in detail here.
In some embodiments of the present application, the interface of the wireless headset charging box 100 employs I2C (I2C Bus, Inter-Integrated Circuit) or UART (Universal Asynchronous Receiver Transmitter/Transmitter) or USB (Universal Serial Bus). I2C is a bi-directional interface standard with a bus arbitration mechanism. The interface of the firmware device 200 in the embodiment of the present application is I2C, which is very suitable for performing short-distance and frequent data communication with the wireless headset charging box 100. The UART converts data to be transmitted between serial communication and parallel communication. The UART only needs to use two wires, has simple circuit structure, wide application and convenient replacement. USB is an external bus standard that specifies the connections and communications between devices. The interface of the firmware device 200 in the embodiment of the application adopts the USB, and the USB is convenient to carry, unified in standard and convenient to use.
It should be noted that, in some embodiments, the interface of firmware apparatus 200 may be implemented not only by I2C or UART or USB, but also by USART (Universal Synchronous and Asynchronous transceiver/Asynchronous Receiver/Transmitter). Those skilled in the art can select the interface of the firmware apparatus 200 according to actual situations, and will not be described in detail here.
Specifically, when the charging device 300 is connected to the upgrading device 400 in the present application, as shown in fig. 4, a communication path is established between the wireless headset charging box 100 and the firmware device 200, and the firmware upgrading of the program firmware of the wireless headset charging box 100 can be completed by using the charging interfaces 110 exposed by the firmware device 200 and the wireless headset charging box 100, so that the structure between the modules is simple, and the firmware upgrading efficiency is high.
In a first aspect, an embodiment of the present application provides a method for upgrading a program firmware, which is applied to the charging device 300.
Referring to fig. 5, fig. 5 is a flowchart of a program firmware upgrading method according to some embodiments of the present application, which specifically includes the steps of:
s100, establishing a communication path with the upgrading device 400, wherein the communication path is established by inserting the upgrading device 400 into the charging interface 110 of the charging device 300;
s200, acquiring an upgrading firmware program sent by upgrading equipment 400 through a communication channel;
s300, carrying out program verification on the obtained upgraded firmware program to obtain a verification result;
and S400, upgrading the firmware according to the verification result.
In step S100, when the firmware of the charging device 300 needs to be upgraded, the charging interface 110 of the charging device 300 may be connected to the upgrading device 400, and a communication path is established between the charging interface 110 and the upgrading device 400 after the connection, so as to receive the upgraded firmware program sent from the upgrading device 400.
In some embodiments, as shown in fig. 6, step S100 further includes the steps of:
s110, checking the charging interface 110 to determine that the upgrade apparatus 400 is inserted into the charging interface 110;
s120, establishing a communication path with the upgrade apparatus 400 according to the checked checking result.
In step S110, after the upgrade apparatus 400 is inserted into the charging interface 110 of the charging apparatus 300, the charging interface 110 needs to be checked, and whether the upgrade apparatus 400 is successfully inserted into the charging interface 110 is determined. This may confirm that the upgrade apparatus 400 is inserted into the charging interface 110 of the charging apparatus 300, and ensure that the upgrade firmware program in the upgrade apparatus 400 can be transferred to the charging apparatus 300.
In step S120, if it is checked that the upgrade apparatus 400 is not inserted into the charging interface 110 of the charging apparatus 300, the upgrade apparatus 400 is reinserted into the charging interface 110 of the charging apparatus 300. If it is checked that the upgrade apparatus 400 is inserted into the charging interface 110 of the charging apparatus 300, a communication path is established between the charging apparatus 300 and the upgrade apparatus 400 for transmitting the upgrade firmware program.
In the embodiment of the present application, the charging interface 110 is checked, so that a situation that the firmware upgrade fails due to the fact that the user cannot successfully insert the upgrade device 400 into the charging device 300 can be avoided, whether a communication path is established between the charging device 300 and the upgrade device 400 can be checked before the firmware is upgraded, and the efficiency of firmware upgrade is improved.
In step S200, the charging apparatus 300 acquires the upgraded firmware program transmitted from the upgrading apparatus 400, and the upgraded firmware program is transferred from the upgrading apparatus 400 to the charging apparatus 300 through the communication path.
In some embodiments, the program verification includes: the first verification and the second verification, as shown in fig. 7, the step S200 further includes the steps of:
step S210, performing first verification on the obtained upgrading firmware program through the MCU 120 to judge that the obtained upgrading firmware program is normal;
step S220, the upgrade firmware program is read and written into the internal program storage area of the MCU microcontroller 120 according to the first verification result, and the internal program storage area performs a second verification on the read and written upgrade firmware program, where the second verification is used to determine that the read and written upgrade firmware program is normal.
The MCU microcontroller 120 performs a first check on the upgrade firmware program transmitted from the upgrade apparatus 400, where the first check is used to determine whether the acquired upgrade firmware program is normal. If it is verified that the acquired upgraded firmware program is not normal, the operation of firmware upgrade is stopped, and the upgrade apparatus 400 is reconnected to the charging interface 110 of the charging apparatus 300. And if the obtained firmware upgrading program is verified to be normal, the next firmware upgrading operation can be carried out. By doing so, whether the firmware upgrading program is completely and accurately transmitted to the MCU 120 can be checked in time, and the accuracy of the firmware upgrading success can be improved.
If the verification result of the first verification fails, the upgraded firmware program is not read and written to the internal program memory area of the MCU microcontroller 120. If the verification result of the first verification is successful and the upgrade firmware program received by the MCU microcontroller 120 is complete and accurate, the upgrade firmware program is read and written into the internal program storage area of the MCU microcontroller 120, then the read and written upgrade firmware program is subjected to second verification by the internal program storage area, and the second verification is used for judging whether the upgrade firmware program read and written by the MCU microcontroller 120 is normal or not. If the second check checks that the upgrade firmware program read from and written to the internal program storage region is not normal, the firmware upgrade operation is stopped, the upgrade device 400 needs to be reconnected to the charging interface 110 of the charging device 300, and if the read upgrade firmware program is checked to be normal, the next firmware upgrade operation can be performed. Therefore, whether the firmware program read and written in the internal program storage area is complete and accurate can be checked in time, and the accuracy of the firmware upgrading success is improved.
Before the firmware is upgraded, the charging device 300 in the embodiment of the present application is checked for multiple times and then stored in the internal program storage area, so that the success rate of the firmware upgrade can be improved, and the efficiency of the firmware upgrade can be improved.
In step S300, the charging device 300 verifies the acquired upgraded firmware program, so that the accuracy of firmware upgrade can be improved.
In step S400, after the firmware upgrade program is verified by the charging device 300, the firmware upgrade of the charging device 300 may be completed according to the firmware upgrade program.
