Detailed Description
The core of the application is to provide a firmware updating method, a firmware updating device, an earphone and a computer readable storage medium, so that firmware updating can be realized without restarting equipment, and further firmware updating efficiency and user experience are improved.
In order to more clearly and completely describe the technical solutions in the embodiments of the present application, 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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Currently, many electronic devices, such as bluetooth headsets, etc., need to solve bugs existing in old versions of firmware through firmware update, or optimize and supplement some current functions, so as to provide better sound quality and interaction experience for users. Due to the function singleness of the electronic equipment such as the earphone and the like, the electronic equipment generally does not have operating systems such as Linux and Android, so that firmware updating cannot be realized by adopting a hot patch technology. In the prior art, generally, firmware is stored in an external FLASH, the firmware is moved by restarting a device, and the old version firmware is stored in an overlay manner, so that the purpose of updating the firmware is achieved. The time required by the firmware updating mode is generally long, and a user can not use the equipment any more during the restarting period, so that the user experience is reduced. In view of the above, the present application provides a firmware updating method, which can effectively solve the above problems.
Referring to fig. 1, an embodiment of the present application discloses a firmware updating method. The firmware updating method can be particularly applied to electronic equipment such as Bluetooth earphones and the like, and mainly comprises the following steps:
s101: after receiving the OTA (Over the Air) update package of the new firmware, the new firmware is stored to the second space block in the FLASH.
Specifically, when the firmware in the electronic device needs to be updated, the electronic device detects a message that the firmware is to be updated, and creates a firmware update task in the background. And, the electronic device may send a firmware update request to the terminal so that the terminal sends an OTA update package of the new version of firmware.
The terminal is in communication connection with the electronic equipment, and can receive the request of the electronic equipment and send the update package to the electronic equipment. The terminal can have an interactive function for a user to input information to select whether to update the firmware. For example, the terminal may be embodied as a user mobile phone, a tablet, a palmtop computer, and the like.
It should be noted that in the embodiment of the present application, two different space blocks are used in FLASH to store the current version firmware and the new version firmware, respectively. The storage area of the current version firmware stored in the FLASH is a first space block, and the other area, namely a second space block, in the FLASH is used for storing the received new version firmware.
After receiving the OTA update package of the new firmware transmitted by the terminal, the electronic device may store the new firmware in the second space block in the FLASH. The second space block is not overlapped with the first space block in the FLASH, wherein the first space block stores the firmware of the current version. That is, the firmware updating method provided in the embodiment of the present application does not move the new version firmware to the location of the current version firmware in an overlay manner, so that the device does not need to be shut down, and the new version firmware can be stored in the second space block in the FLASH of the electronic device while the current version firmware is running.
S102: and backing up the resource data of the current version firmware stored in the first memory block to the second memory block.
Specifically, when the firmware of the business app is running, the firmware generally includes resources such as a code segment, an initialized data segment, an uninitialized data segment, a heap, a stack, and the like, referring to fig. 2, fig. 2 is a resource distribution diagram of the firmware in the memory according to the embodiment of the present application. Generally, the resources of a firmware include the following:
the code segment, text, is usually used for storing program execution code, and may include some read-only constant variables, such as string constants and the like;
the initialized data segment is usually used for storing initialized global variables in a program and belongs to static memory allocation;
uninitialized data segments, also called bss segments, are usually used to store global variables and static variables that are uninitialized or initialized to 0 in a program;
heap, used for depositing the memory segment that is distributed dynamically in the course runs, its size is not fixed, can expand or reduce dynamically;
the stack is used for storing local variables of the program; or for passing parameters and return values when the function is called; the method has the characteristic of first-in first-out and is suitable for saving/restoring the calling site.
It should be noted that, similarly to the case that the FLASH memory is occupied by the current version firmware and the new version firmware respectively in two different space blocks, in the embodiment of the present application, two storage areas are also similarly set in the memory to store resource data of the two versions of firmware respectively, so as to operate the corresponding versions of firmware. The first memory block is used for storing resource data of a current version of firmware, and the second memory block is used for storing resource data of a new version of firmware.
In order to implement background silent update of firmware without restarting the electronic device, in the embodiment of the present application, the resource data of the current version firmware stored in the first memory block is backed up to the second memory block, so that the resource data of the two versions of firmware are integrated in the following.
S103: and according to the resource data of the new firmware version obtained by analysis, performing resource data integration on the second memory block.
Specifically, after the resource data of the new version of firmware is analyzed, the resource data integration processing may be performed on the second memory block, so as to integrate the resource data of the current version of firmware and the resource data of the new version of firmware. It is easy to understand that the new version of firmware may perform bug fixing, function optimization, new function addition, and the like on the current version of firmware, and therefore, the resource data of the current version of firmware may be subjected to integration operations such as constraint, deletion, modification, addition, and the like, so that the business app program can smoothly perform after entering the new version of firmware.
S104: and jumping the program pointer to the new firmware.
Specifically, after the integration of the resource data of the second memory block is completed, the program pointer may be skipped from the currently running current version firmware to enter the new version firmware for running. The resource data of the new version firmware in the memory is integrated with the resource data of the current version, so that the smooth switching of the two versions of firmware can be effectively realized under the condition of not restarting the equipment.
The firmware updating method provided by the embodiment of the application comprises the following steps: after receiving the OTA update package of the new firmware, storing the new firmware to a second space block in the FLASH; the second space block is not overlapped with the first space block stored with the firmware of the current version; backing up the resource data of the current version firmware stored in the first memory block to a second memory block; according to the resource data of the new firmware version obtained through analysis, resource data integration is carried out on the second memory block; and jumping the program pointer to the new firmware.
Therefore, the current version firmware and the new version firmware are separately stored in the FLASH, and the resource data of the new version firmware is integrated in the memory by combining the resource data of the current version firmware, so that the two versions of firmware can be smoothly switched without restarting the equipment, a user can continuously use the equipment during the firmware updating period, the time required by the firmware updating is effectively shortened, and the user experience and the firmware updating efficiency are greatly improved.
As a specific embodiment, on the basis of the foregoing, the firmware updating method provided in this embodiment of the present application further includes, after performing resource data integration on the second memory block:
modifying the preset firmware selection mark according to the address of the second space block; the preset firmware selection flag is used for selecting the firmware to be run after the device is restarted.
Specifically, since the embodiment of the present application stores two different versions of firmware in FLASH, the firmware that the electronic device selects to run after being restarted needs to be set. Therefore, the preset firmware selection flag is set in the embodiment of the application, and when the bootloader program is restarted and run by the electronic device, the firmware to be run is selected according to the preset firmware selection flag.
On the basis of the above, referring to fig. 3, fig. 3 is a schematic view of a storage structure of a FLASH disclosed in the embodiment of the present application.
Generally, a software system of an electronic device is divided into two parts: hardware initialization program and business app software. For a simple embedded device, in order to facilitate firmware OTA update, a software system of the embedded device is generally divided into two parts, namely a bootloader program and business app firmware. The bootloader program is generally used to complete hardware initialization, service app firmware migration, and a function of jumping to the service app firmware, where the function of migrating the service app firmware refers to a function of migrating a new version of firmware in the external FLASH to a current version of firmware in a covered manner in the shutdown condition when it is detected that the firmware needs to be updated in the prior art.
The storage structure of FLASH shown in fig. 3 adopts a software mode of bootloader + app, and stores:
the bootloader is used for completing initialization work of electronic equipment hardware and carrying out skip operation according to a preset firmware selection mark;
presetting a firmware selection mark, which is the basis for the bootloader to select which firmware to jump to;
the firmware 1 is the current version firmware of the device service app and is stored in a first space block, and the corresponding compiling link address is addr;
firmware 2, which is a new version of the device service app, is stored in the second space block, and the corresponding compiling link address is addr: d;
other information of the device.
On the basis of the above, referring to fig. 4, fig. 4 is a schematic view of a storage structure of a memory disclosed in the embodiment of the present application. In this embodiment, the memory includes:
the critical ram area is used for jumping from the current version firmware to the new version firmware for use, and the addr: a1 is used as a starting address;
the first memory block is used for storing resource data used by the current version firmware, and takes addr: a2 as a starting address;
and the second memory block is used for storing the resource data used by the new firmware, and takes addr: a3 as a starting address.
As a specific embodiment, in the firmware updating method provided in the embodiment of the present application, based on the above, the jumping the program pointer to the new firmware version in step S104 may specifically include:
setting a program jump point at a corresponding position of the new version firmware according to a current program operating point of the current version firmware;
and jumping the program pointer from the current program running point of the current version firmware to the program jumping point of the new version firmware.
Specifically, in order to implement seamless switching operation of two versions of firmware, so that the new version of firmware directly replaces operation at the current operation interface of the current version of firmware, the embodiment of the present application further sets a program jump point in the new version of firmware as a jump entry of the program pointer.
As a specific embodiment, the firmware updating method provided in the embodiment of the present application, based on the above contents, jumps a program pointer from a current program running point of a current version of firmware to a program jump point of a new version of firmware, and includes:
skipping a program pointer from a current program running point of the current version firmware to a bootloader program so as to perform address conversion processing on the first memory block and the second memory block;
and jumping the program pointer to a program jump point of the new firmware version by the bootloader program.
Specifically, considering that the "new version firmware" updated this time will become the "current version firmware" updated next time, in order to avoid modifying the compiling addresses of the current version firmware and the new version firmware at the next update, in this embodiment of the application, after the resource data is integrated in step S103 of the update this time, the address conversion between the first memory block and the second memory block may be performed.
Referring to fig. 5, fig. 5 is a schematic diagram of memory address translation disclosed in the embodiment of the present application. After address conversion, the first memory block before conversion will become the second memory block after conversion, and the second memory block before conversion will become the first memory block after conversion.
It is easy to understand that, when performing the memory address translation, it is necessary to quit the program from the currently running current version firmware, that is, jump the program pointer from the current program running point of the current version firmware to the bootloader program, so as to perform the address translation on the first memory block and the second memory block.
As a specific embodiment, the firmware updating method provided in this embodiment of the present application, based on the foregoing, performs address conversion processing on a first memory block and a second memory block, and includes:
and performing address conversion processing on the first memory block and the second memory block based on the externally connected address conversion chip and the peripheral memory.
It is easy to understand that when the memory resource of the electronic device is sufficient, the memory resource can be directly utilized to perform address conversion; but when the memory resource of the electronic equipment is insufficient, the address conversion can be carried out based on the external address conversion chip and the peripheral memory. Specifically, referring to fig. 6, fig. 6 is a schematic diagram illustrating an implementation manner of memory address translation disclosed in the embodiment of the present application.
The soc (system on chip or system on chip) is an integrated circuit of the memory and the FLASH in the electronic device.
The external address conversion chip is an addr switch and is used for converting the address of the peripheral memory; the special chip may be specifically adopted, and may also be implemented based on a Programmable Logic Device such as a CPLD (Complex Programmable Logic Device), an FPGA (Field Programmable Gate Array), and the like.
The peripheral memory is external ram, and SDRAM, DDR, etc. can be selected.
