Example 1

Fig. 1 is a flowchart of a firmware upgrading and restoring method according to an embodiment of the present invention, where the method may be performed by a firmware upgrading and restoring device, and the firmware upgrading and restoring device may be implemented in hardware and/or software, and the firmware upgrading and restoring device may be configured in a chip. As shown in fig. 1, the method includes:

s110, acquiring a file to be upgraded of the current system, and calling a guide program according to the file to be upgraded, wherein the file to be upgraded comprises firmware information to be upgraded.

The current system refers to a single-chip microcomputer (Micro Control Unit, MCU) system, in particular to an MCU with application programming (InApplicationProgramming, IAP) capability, and the IAP is a program of a user to burn a partial area of the UserFlash in the running process, so that the firmware program in the product can be updated and upgraded conveniently through a reserved communication port after the product is released. The bootstrap program is a bootloader program for booting an operating system, and it should be noted that, in this embodiment, the internal false of the MCU is divided into 4 areas, and "bootloader", "running APP", "code register 1", and "code register 2" are stored respectively. For an MCU with IAP self-programming capability, support space download Technology (OTA) upgrade, OTA upgrade code is typically composed of a bootstrap Bootloader and an application program APP. OTA upgrading refers to downloading and upgrading files (such as problem repairing and version updating) needed by a system through a wireless network, and the files are directly downloaded through a wireless environment without downloading and upgrading through wired connection. The system can be improved in function by upgrading the firmware of the system, the stability of the system is enhanced, and the system loopholes are repaired.

Specifically, when a user needs to perform firmware upgrade, the system can call an operation program of the current system based on an upgrade instruction and the firmware information to be upgraded, wherein the operation program is used for receiving the firmware information to be upgraded and sending the firmware information to be upgraded to a first designated address, the first designated address refers to a code temporary storage area 1 in a flash, and the system can take the firmware information to be upgraded in the code temporary storage area 1 as a file to be upgraded. It should be noted that, the code temporary storage area 1 only stores the firmware information to be upgraded which is upgraded once, and when new firmware information to be upgraded is written, the previously written firmware information is automatically deleted.

Specifically, after the running program stores the firmware information to be upgraded in the code temporary storage area 1, an upgrade flag is written, and at the moment, the system jumps to the boot program, i.e. a designated interface is called according to the upgrade flag, and the boot program is called through the designated interface.

S120, generating a current firmware file based on the bootstrap program.

Specifically, the bootstrap program is used for judging whether the system needs to be upgraded, and if the system needs to be upgraded, the old firmware copy is stored in the code temporary storage area 2 to generate the current firmware file.

S130, upgrading and restoring the system firmware according to the current firmware file and the file to be upgraded.

Fig. 2 is a flowchart of a firmware upgrading and restoring method according to an embodiment of the present invention, and step S130 mainly includes steps S131 to S135 as follows:

s131, upgrading the system firmware through the file to be upgraded, and generating a new version mark to replace the upgrading mark.

Specifically, when firmware is updated, the boot program uses the file to be updated in the code temporary storage area 1 to cover the firmware information of the old version, then clears the update flag, writes a new version flag, and then calls the designated interface to make the system jump from the boot program to the operating program.

S132, acquiring the running state of the current system, wherein the running state comprises normal running and abnormal running.

S133, judging whether the operation state is normal, if so, executing S134, otherwise, executing S135.

S134, deleting the new version mark and generating an upgrade completion prompt.

Specifically, since the APP is running normally, the new version flag needs to be cleared. Therefore, the system can judge the running state after the firmware is upgraded, the running state of the system can be obtained to be normal running or abnormal running, when the running state is normal running, the new version mark can be cleared, an upgrade completion prompt is generated, then the upgrade completion prompt is displayed to a user, the user can normally use the system after receiving the upgrade completion prompt, the running problem of the system is avoided, the user is ensured to normally use the system, and meanwhile, the stability of the system upgrading process is also ensured.

S135, restoring the system firmware according to the current firmware file, and generating an upgrade abnormality prompt.

Specifically, firmware restoration refers to removing new version firmware information and restoring old version firmware information to restore the system under the condition of abnormal upgrading. When the running state of the system is abnormal, the system can restore the system firmware according to the current firmware file (old version firmware information) of the code temporary storage area 2 and generate an upgrade abnormal prompt to prompt a user, so that the user can conveniently grasp the situation of the upgrade abnormal in time, and the user can check and adjust the input firmware information to be upgraded, thereby ensuring the subsequent system firmware upgrade and normal running. The specified mode includes voice or image, the voice can be broadcast through a speaker connected with the controller, for example, the voice content can be: firmware upgrade is abnormal. The image can be displayed through a user terminal connected with the system so as to prompt the user. Further, when firmware restoration is performed, the system uses the file to be updated at the designated position of the running program as second target information, and then replaces the current firmware file stored in the code temporary storage area 2 to implement firmware restoration.

For example, when the updated program is found to be hung up, the system detects that the running state is abnormal, at this time, the device may perform a restart operation to restart, and if the bootstrap program detects that the new version flag is not cleared, copies a current firmware file from the code temporary storage area 2 to cover the file to be updated at the designated position of the running area, clears the new version flag, and jumps to the running program, so that problems occur and re-burning can be avoided.

Example two

Fig. 3 is a flowchart of a firmware upgrading and restoring method according to a second embodiment of the present invention, where a specific process of generating a current firmware file based on a boot strap program is added on the basis of the first embodiment. The specific contents of steps S210 and S250 are substantially the same as steps S110 and S130 in the first embodiment, so that a detailed description is omitted in this embodiment. As shown in fig. 3, the method includes:

s210, acquiring a file to be upgraded of the current system, and calling a guide program according to the file to be upgraded, wherein the file to be upgraded comprises firmware information to be upgraded.

S220, acquiring an upgrade state detection condition through a bootstrap program, wherein the upgrade state detection condition comprises to-be-upgraded and no need of upgrade.

Specifically, whether the updating is needed or not can be judged through the bootstrap program, if the updating is needed, the new firmware in the code temporary storage area is covered with the old firmware, after the covering is successful, the updating mark is cleared, and the operation is skipped to the new firmware. The embodiment of the invention is suitable for firmware upgrade of the MCU in the embedded system. When the MCU of the user equipment is powered on or the software is reset, a program pointer of the MCU points to a reset vector, at the moment, whether the effective identification of the equipment application program exists in a memory of the MCU or not can be detected by a guide program to judge the upgrade state detection condition of the system, the effective identification of the equipment application program is the identification for judging whether the application program in the user equipment is effective, when the effective identification of the equipment application program exists, the application program in the user equipment is in an effective state, at the moment, the upgrade state detection condition is that the application program on the user equipment is not required to be upgraded, and the application program on the user equipment can be directly operated, otherwise, the upgrade state detection condition is that the upgrade is required to be upgraded, and firmware upgrade is required to be carried out on the MCU to repair the application program control loophole or defect of the user equipment. The MCU is powered on, namely the MCU is powered on, the MCU software resets, namely the MCU program pointer points to the reset vector through the program instruction, and the memory of the MCU is the Flash memory of the MCU.

And S230, when the upgrade state detection condition is detected to be upgraded, extracting the current firmware information of the appointed position of the running program.

Specifically, when it is detected that the upgrade status is to be upgraded, current firmware information of a designated position in an operating program needs to be extracted before upgrading system firmware, that is, when it is detected that no effective identifier of an application program of a device exists on the MCU, it is indicated that the application program in the user equipment is in a failure status, and at this time, firmware upgrading needs to be performed on the MCU. And, the current firmware information of the designated location in the running program needs to be extracted before the system is firmware upgraded.

S240, copying the current firmware information to the second designated address to generate a current firmware file.

Specifically, the current firmware information, namely the estimation information of the running version of the current system, is copied to the second designated address by the bootstrap program to generate the current firmware file, so that the current estimation information is stored, the restoration of the system firmware can be realized by extracting the current firmware file under the condition of abnormal estimation and upgrading, the re-burning of the system is avoided, and the stability of the system is ensured.

S250, upgrading and restoring the system firmware according to the current firmware file and the file to be upgraded.
