Detailed Description
The embodiment of the invention provides a method, a device, equipment and a storage medium for upgrading system firmware.
The terms "first," "second," "third," "fourth" and the like in the description and in the claims and in the above drawings, if any, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments described herein may be implemented in other sequences than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus.
For easy understanding, the following describes a specific flow of an embodiment of the present invention, referring to fig. 1, and an embodiment of a method for upgrading system firmware in an embodiment of the present invention includes:
101. when an upgrade instruction is detected, downloading new firmware to a backup area according to the upgrade instruction;
specifically, the upgrade instruction may be initiated by the general server, and detected by the upgrade device of the system firmware, and when the upgrade instruction is detected, a new firmware is downloaded based on the upgrade instruction by presetting a download address, where the new firmware is stored in the backup area. Further, the upgrade instruction is analyzed to obtain a file download address, and the new firmware is downloaded to the backup area according to the file download address.
Alternatively, the downloading of the new firmware is divided into Uboot downloading and WebUI/OTA downloading.
Optionally, when the upgrade instruction is detected, downloading the new firmware to the RAM according to the upgrade instruction; writing the size of the new firmware into the last four bytes of Flash and transferring the new firmware to the backup area; the step of performing cyclic redundancy check on the new firmware when the new firmware is complete includes: and when the new firmware is complete, performing cyclic redundancy check on the new firmware according to the last four bytes of the Flash.
Optionally, when the upgrade instruction is detected, downloading the new firmware to the backup area according to the upgrade instruction and writing the new firmware into the last four bytes of Flash; the step of performing cyclic redundancy check on the new firmware when the new firmware is complete includes: and when the new firmware is complete, performing cyclic redundancy check on the new firmware according to the last four bytes of the Flash.
Optionally, each product of the combination of software and hardware has a storage component that stores system firmware, where the storage component may divide a plurality of areas, and in this embodiment, the area division of the storage component is divided into a Uboot, an auxiliary area, a backup area, and a main partition, with reference to fig. 2.
The partitions function as follows:
uboot: the area stores the program executed first after the equipment is powered on, and has the function of checking whether the backup area has the newly downloaded firmware, and if so, identifying the newly downloaded firmware to ensure that the newly downloaded firmware is not abnormal;
auxiliary area: auxiliary data required for the operation of the regional storage device;
main partition: the area stores actually executed system firmware, namely the system firmware used when the equipment normally operates;
backup area: the area stores newly downloaded system firmware to be upgraded and auxiliary data areas used for the upgrade.
The internal structure of the backup area is referred to in fig. 3.
Wherein, each part is described as follows:
firmware area: storing firmware to be upgraded used for actual operation;
and (3) checksum: following the four byte region of the firmware, each byte value of the firmware is summed in turn to a resulting four byte value. Checksum (checksum) is used in the field of data processing and data communications to check the sum of a set of data items at a destination. It is typically in the form of a hexadecimal representation of a number system. If the value of the checksum exceeds hexadecimal FF, i.e., 255, its complement is required as the checksum. Are commonly used to ensure data integrity and accuracy in communications, particularly in long-range communications.
Firmware size: the last four bytes of the backup area, the value is the firmware size plus the checksum area size (4 bytes).
102. Determining whether the new firmware is complete;
specifically, the file integrity of the new firmware is checked. The file integrity check is the "validation" of the file. An attacker may add malicious code to the software and when such tampered software is downloaded and used, a computer virus or Trojan horse program may silently enter the user's computer. The integrity of the file is checked, i.e. whether the downloaded software has been tampered with.
A common method of file integrity verification is to use a "hash function" based verification algorithm. Before releasing the software, a software developer uses a certain verification algorithm to calculate the characteristic value of the exe file, and then releases the characteristic value and the exe file together on a network. The user uses the same verification algorithm to calculate the feature value downloaded to the exe file and compares the feature value with the feature value issued by the software developer. If the two eigenvalues are the same, the downloaded exe file is considered correct. If the two characteristic values are different, the downloaded exe file is considered tampered.
Optionally, identifying whether the new firmware is broken; when the new firmware is damaged, continuing to run the historical firmware of the main partition; and when the new firmware is not damaged, executing the step of determining whether the new firmware is complete.
Optionally, identifying whether the new firmware is broken; when the new firmware is damaged, returning to execute the step of downloading the new firmware to the backup area according to the upgrading instruction; and when the new firmware is not damaged, executing the step of determining whether the new firmware is complete.
103. When the new firmware is complete, performing cyclic redundancy check on the new firmware;
specifically, cyclic redundancy check (Cyclic redundancy check, collectively referred to as "CRC") is a hash function that generates a short fixed-bit check code based on data such as network packets or computer files, and is used to detect or check errors that may occur after data transmission or storage. The generated numbers are calculated before transmission or storage and appended to the data, and then the recipient checks to determine if the data has changed.
CRC is one of the checksums, which is the remainder of a division of two byte data streams by binary division (no carry, XOR instead of subtraction). Wherein the dividend is a binary representation of the information data stream requiring the checksum to be calculated; the divisor is a predefined (short) binary number of length (n+1), typically represented by the coefficients of a polynomial. N 0 s are added to the information data before division.
Optionally, when the new firmware is complete, determining whether the Kernel CRC32 value of the new firmware is correct, so as to perform cyclic redundancy check on the new firmware. CRC32 means that a 32bit (8 bit hexadecimal number) check value is generated. Since each bit of the source data block participates in the calculation when the CRC32 generates the check value, a different CRC32 value is obtained even if only one bit of the data block is changed. CRC32 means that 32 bits are used to hold error checking information, and when new firmware is created, the details of CRC32 will be embedded in the file to ensure that it can be detected if it has been corrupted when the file is restored to disk. Indicating that CRC32 is in error, the new firmware may be corrupted.
Optionally, when the result of the cyclic redundancy check is an error, erasing the new firmware in the backup area and returning to execute the step of downloading the new firmware to the backup area according to the upgrade instruction; and outputting prompt information of verification problem of the firmware security packet when the result of the cyclic redundancy check is in secondary error. In this alternative embodiment, based on the result of the cyclic redundancy check, multiple error determinations are performed, so as to effectively determine whether a problem occurs locally or whether a problem exists in the new firmware itself, so as to quickly check out the core cause of the upgrade failure.
104. And when the result of the cyclic redundancy check is correct, transferring the new firmware to a main partition and operating.
Optionally, when the result of the cyclic redundancy check is correct, copying the new firmware to the main partition; and erasing the new firmware of the backup area.
In the embodiment of the invention, when an upgrade instruction is detected, new firmware is downloaded to a backup area according to the upgrade instruction; determining whether the new firmware is complete; when the new firmware is complete, performing cyclic redundancy check on the new firmware; and when the result of the cyclic redundancy check is correct, transferring the new firmware to a main partition and operating. Because the upgrade equipment of the system firmware is firstly placed in the backup area to carry out the integrity check and the cyclic redundancy check in the firmware upgrade process, the probability of upgrade failure caused by the occurrence of problems of the new firmware can be reduced, the possibility that the upgrade equipment of the system firmware is abnormal in the upgrade of the system firmware is effectively avoided, the normal upgrade of products is ensured to avoid the equipment cannot be used because of the abnormal upgrade of the system firmware, and further, the cost and the cost of a large amount of after-sale maintenance and equipment replacement are prevented, the use effect of the equipment can be continuously upgraded, and the maintenance cost of the system firmware is reduced.
