[0039] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. The components of the embodiments of the present application usually described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, each other embodiment obtained by those skilled in the art without making creative work belongs to the scope of protection of the present application.

[0040] First, the application scenarios to which the present application is applicable are introduced. The present application can be applied in the field of computer technology.

[0041] Wide application of embedded systems in multiple fields: Embedded systems have shown broad application prospects in the fields of automobiles, medical equipment, smart homes and industrial automation. For example, in the automotive industry, with the development of intelligent driving technology, embedded systems are used in in-vehicle entertainment, navigation and security monitoring. In the field of medical equipment, embedded systems are used for real-time monitoring and data collection to improve the efficiency and accuracy of equipment. In addition, smart homes and industrial automation are also important application areas of embedded systems. With the use of embedded devices and the update and iteration of technology, the upgrade of equipment is very important.

[0042] According to research, the existing technology for upgrading embedded devices generally connects to the device through a physical interface such as a serial port, JTAG interface or USB, and then uses a dedicated software tool to update the firmware. When there are many types of similar devices, upgrading the firmware error can easily cause the device to get stuck and become a brick. And during the upgrade process, if there is a power outage, data transmission error, etc., the device may fail to start or malfunction. Therefore, comprehensive security measures are needed to ensure the security and reliability of the upgrade process.

[0043] Based on this, an embodiment of the present application provides a software program upgrade method for an embedded device. Through the data two-way comparison and verification technology, the maintenance stability of the embedded device is improved, the stability of program writing is ensured, the efficiency and security of software program upgrades are improved, and the problem of upgrade failure caused by an abnormality in a certain bit of the data packet due to single-way writing is avoided.

[0044] See also Figure 1 , Figure 1 This is a flowchart of a method for upgrading a software program of an embedded device provided in an embodiment of the present application. Figure 1 As shown in , the software program upgrade method provided in the embodiment of the present application includes:

[0045] S101, when it is detected that an upgrade data packet is connected to the embedded device and the upgrade data packet is verified, controlling the embedded device to receive the upgrade data packet.

[0046] Here, for the above step S101, in a specific implementation, when an external device connects an upgrade data packet to an embedded device, the upgrade data packet needs to be verified first. After the upgrade data packet is verified, the upgrade data receiving process starts to control the embedded device to receive the upgrade data packet.

[0047] As an optional embodiment, before detecting that the upgrade data is connected to the embedded device, the software program upgrade method provided in the embodiment of the present application further includes:

[0048] The device firmware information corresponding to the embedded device is stored in the configuration database.

[0049] Here, in the specific implementation, the configuration database stores the device firmware information of the embedded device. When the upgrade data packet is transmitted to the embedded device, the device firmware information needs to be compared with the version information of the upgrade data packet. If the comparison is consistent, it means that the upgrade data packet meets the verification, and the software program will be upgraded.

[0050] Specifically, with respect to the above step S101, the following steps are performed to determine whether the upgrade data package has passed the verification:

[0051] The version information corresponding to the upgrade data packet is obtained, and when it is determined that the device firmware information stored in the configuration database matches the version information, it is considered that the upgrade data packet has passed verification.

[0052] For the above steps, during the specific implementation, the version information corresponding to the upgrade data packet is obtained to determine whether the device firmware information of the embedded device matches the version information of the upgrade data packet. When the information matches, it can be determined that the upgrade data packet has been verified and the following upgrade steps can be executed.

[0053] As an optional embodiment, after determining that the information matches, an XOR algorithm can be used to perform algorithmic operations, decrypt the upgrade encryption code, and perform upgrade code comparison after decryption to ensure the stability and reliability of the data source.

[0054] S102, writing each upgrade data packet received by the embedded device into a first address and a second address in a storage unit of the embedded device respectively, and comparing the upgrade data packets written in the first address and the second address one by one.

[0055] For the above step S102, when it is specifically implemented, the receiving process of the upgrade data packet is started, each upgrade data packet received by the embedded device is written into the first address and the second address in the storage unit of the embedded device respectively, and the upgrade data packets written in the first address and the second address are compared one by one. Specifically, each time the embedded device receives an upgrade data packet, the upgrade data packet is written into the first address and the second address respectively. After each upgrade data packet is written, the next upgrade data packet is read and the next upgrade data packet is continued to be written into the first address and the second address until all the upgrade data packets are fully written. When the data writing process is completed, the upgrade data packet in the first address and the upgrade data packet in the second address are compared one by one. Once the data comparison is inconsistent, the upgrade process is stopped immediately, and it is considered that this upgrade fails. If the upgrade is not performed, the default software program is started. In this way, when the upgrade process is abnormally interrupted, the default software program will be started, and the upgrade process will not destroy the default program.

[0056] S103, when the data in the first address is consistent with the data in the second address, the payload data of each upgrade data packet is written into the third address and the fourth address in the storage unit, and the upgrade data packets written in the third address and the fourth address are compared one by one.

[0057] Here, the payload data refers to the data obtained after removing the integrity check data code (CRC, CyclicRedundancy Check) in the upgrade data packet. The integrity check data code is a very common check code. On computer networks, it is widely used in communication protocols, disk storage, etc. The core principle of the CRC code is: when sending or receiving data, the data is encoded according to a specific algorithm and sent to the receiver. After receiving the data, the receiver also decodes it according to the same algorithm. If the decoding result of the receiver is consistent with the encoding result of the sender, it means that the data has not been tampered with or damaged.

[0058] With respect to the above step S103, in the specific implementation, when the data in the first address is consistent with the data in the second address, the integrity check data code in each upgrade data packet is removed, and the payload data of each upgrade data packet is written to the third address and the fourth address. After the writing is completed, each upgrade data packet at the third address and the fourth address is read packet by packet to perform data comparison. If the comparison fails, the upgrade process is exited and the upgrade is considered to have failed. If the upgrade is not performed, the default software program is started.

[0059] S104, when the data in the third address is compared with the data in the fourth address and they are consistent, the software program of the embedded device is upgraded using the upgrade data packet.

[0060] With respect to the above step S104, when the data in the third address is compared with the data in the fourth address and is consistent, the software program of the embedded device is upgraded using the upgrade data packet, and the upgrade is considered successful. In this way, the stability of program writing is ensured by the double verification mechanism of the above steps S102 and S103, the efficiency and safety of software program upgrade are improved, and the problem of upgrade failure caused by an abnormality of a certain bit of the data packet due to single-channel writing is avoided.

[0061] As an optional embodiment, after the software program of the embedded device is upgraded using the upgrade data packet, the software program upgrade method provided in the embodiment of the present application further includes:

[0062] An upgrade flag in the embedded device is set; the embedded device is controlled to restart, and when the upgrade flag is identified, the upgraded software program is started.

[0063] For the above two steps, when the software program is successfully upgraded, the upgrade flag in the embedded device is set. At this time, the embedded device is controlled to restart. After the embedded device restarts again, the secondary boot program will judge the upgrade flag. When the upgrade flag is identified, the upgraded software program is started. This ensures the stability of the device, and once the upgrade process is terminated, it can ensure that the backup program is not disturbed, and the upgrade flag can be maintained at the first time to ensure that the embedded device will not be unusable.

[0064] The method for upgrading the software program of an embedded device provided in an embodiment of the present application includes: first, when it is detected that an upgrade data packet is connected to the embedded device and the upgrade data packet is verified, the embedded device is controlled to receive the upgrade data packet; then, each upgrade data packet received by the embedded device is written to a first address and a second address in a storage unit of the embedded device, respectively, and the upgrade data packets written in the first address and the second address are compared one by one; when the data in the first address is consistent with the data in the second address, the payload data of each upgrade data packet is written to a third address and a fourth address in the storage unit, and the upgrade data packets written in the third address and the fourth address are compared one by one; finally, when the data in the third address is consistent with the data in the fourth address, the upgrade data packet is used to upgrade the software program of the embedded device.

[0065] This application first writes the received data packets into two different addresses of the embedded device for data comparison, and then writes the payload data into two different addresses for data comparison. The data upgrade is performed only after the two data comparisons are consistent. Through the data dual-path comparison and verification technology, the maintenance stability of the embedded device is improved, the stability of program writing is ensured, the efficiency and security of software program upgrades are improved, and the upgrade failure caused by an abnormal bit of the data packet due to single-path writing is avoided.
