s11: and if the system needs to be upgraded in the running process of the system, determining any storage partition which is not currently operated in the system as a current upgrading partition.
With the improvement of the technology level and the improvement of the chip manufacturing process, the chip cost is lower and lower, so that the embedded device can use a large memory, a large flash memory and the like, the system in the embodiment of the application can be a system in the embedded device, and of course, other settings carried out according to the requirements are also within the protection scope of the invention; the system may be an operating system or other systems set according to actual needs, and the storage partition is a part of a physical disk and functions as a physical partition unit. If the system needs to be upgraded in the running process of the system, the storage partition where the system currently runs and the storage partition where the system does not run can be determined first, and the storage partitions are all the storage partitions capable of achieving the upgrading and running of the system, that is, in the embodiment of the present application, at least two storage partitions capable of achieving the upgrading and running of the system can be set, and then at the same time, the system runs on the storage partition capable of achieving the upgrading and running of the system, and the system does not run on the storage partition capable of achieving the upgrading and running of the system.
S12: and determining the firmware for realizing system upgrading as upgrading firmware, and writing the upgrading firmware into the current upgrading partition.
When system upgrade is needed to be realized in the embodiment of the application, the latest firmware (firmware can be an upgrade package) is written into the corresponding storage partition, and then the system is restarted from the storage partition in which the firmware is written, so that the upgrade of the system is realized; and during the process of realizing system upgrade (before the system is successfully restarted after firmware writing), the system still continues to run in the currently running memory partition. According to the method and the device, any storage partition where the system does not operate currently is used as the current upgrading partition, and then the firmware for achieving system upgrading is written into the current upgrading partition when the system upgrading is achieved, so that the system is restarted from the current upgrading partition after the writing is successful, and the system operates in the current upgrading partition after being restarted.
S13: and after the upgrade firmware is successfully written, restarting the system from the current upgrade partition so that the system runs in the current upgrade partition.
Briefly, when two storage partitions capable of implementing system upgrade operation are respectively denoted as partition a and partition B, if the system needs to be upgraded, switching is performed between partition a and partition B, for example, when the system is currently running in partition a, firmware used for upgrade is written into partition B, the system is restarted from partition B after the writing is successful, and firmware used for upgrade is written into partition a in the next upgrade, and so on.
The method and the device have the advantages that the number of the storage partitions capable of achieving system upgrading operation is at least two, then when the system needs upgrading, the firmware used for upgrading is written into the storage partitions which are not operated by the system at present, then the system is restarted from the storage partitions in which the firmware is successfully written after the firmware is successfully written, the system is upgraded, the firmware used for upgrading is still written into the storage partitions which are not operated by the system at present when the system needs upgrading next time, and the like. Therefore, the method and the device have the advantages that the running storage partition and the upgraded storage partition are separated, so that the normal work of the running storage partition of the system is not influenced in the upgrading process, software does not need to be closed, storage is not unloaded, and the like, and the upgrading efficiency can be effectively improved; even if abnormal power failure and other conditions occur in the upgrading process, the system can be restarted from the storage partition operated before the firmware is written, the starting of the system cannot be influenced, the product stability is good, and the maintenance difficulty is small; in conclusion, the system upgrading efficiency is effectively improved, meanwhile, the system stability can be improved, and the maintenance difficulty is reduced.
The system upgrading method provided by the embodiment of the present invention, after determining that the firmware for implementing system upgrading is upgraded firmware, may further include:
reading a check value contained in the upgrading firmware to be a current check value, and reading a data part contained in the upgrading firmware to be a first data part;
and calculating the data in the first data part to obtain a corresponding check value as a first check value, comparing the first check value with the current check value, if the comparison result is consistent, executing the step of writing the upgrade firmware into the current upgrade partition, otherwise, determining that the system cannot be upgraded based on the upgrade firmware.
After the upgrading instruction is received, the embodiment of the application can determine that the system needs to be upgraded, and then upgrade the corresponding system. In order to ensure the accuracy of the firmware upgrading, the embodiment of the application can firstly verify the firmware upgrading; specifically, the verification value may be read from the upgrade firmware header portion, and the verification value of the data in the upgrade firmware data portion may be calculated, and then the two are compared, and if the two are the same, the verification is passed, otherwise, the verification is failed. The check value may specifically be a CRC checksum, and the firmware used for upgrading may be a corresponding firmware image.
In the system upgrading method provided in the embodiment of the present invention, after determining that the first check value is consistent with the current check value, the method may further include:
reading version information contained in the upgraded firmware as first version information, and reading the version information of the firmware in a storage area where the system currently operates as second version information;
and comparing the first version information with the second version information, if the comparison result is consistent, determining that the system is not required to be upgraded based on the upgraded firmware, otherwise, executing the step of writing the upgraded firmware into the current upgraded subarea.
In order to further ensure that the upgraded firmware is the latest version of firmware, the embodiment of the application can verify the version of the upgraded firmware; specifically, the version information of the firmware header portion may be read, the version information may be compared with the version information of the stored firmware read in the storage partition in which the system currently operates, if the version information is different from the version information of the stored firmware read in the storage partition, the system needs to be updated, the updated firmware is the latest version of firmware, and otherwise, it is determined that the system is not to be updated based on the updated firmware. The version information may be a version number.
The system upgrading method provided by the embodiment of the present invention, after the firmware is successfully written in and upgraded, may further include:
reading a data part contained in the upgrading firmware in the current upgrading partition as a second data part, and calculating data in the second data part to obtain a corresponding check value as a second check value;
and comparing the second check value with the current check value, if the comparison result is consistent, executing the step of restarting the system from the current upgrading partition, and otherwise, determining that the system cannot be restarted from the current upgrading partition.
In order to further ensure the accuracy of updating the firmware, the embodiment of the application can also perform read-back verification; specifically, in the embodiment of the application, data in a data portion of firmware can be read from a storage partition in which upgrade firmware is written, the read data is calculated to obtain a corresponding check value, the check value read from the upgrade firmware before the upgrade firmware is written is compared with the check value calculated here, if the two check values are the same, it is indicated that the upgrade firmware written into the current upgrade partition has no problem, and therefore the system can be restarted from the current upgrade partition, and otherwise, it is indicated that the upgrade firmware written into the current upgrade partition has a problem, and therefore the system cannot be restarted from the current upgrade partition.
Before writing the upgrade firmware into the current upgrade partition, the system upgrade method provided in the embodiment of the present invention may further include:
and erasing the data stored in the current upgrading partition.
In order to further ensure effective implementation of upgrading, in the application, before the upgrade firmware is written in, data stored in the current upgrade partition can be erased, and then the upgrade firmware is written in the current upgrade partition, so that storage of invalid data is avoided, and further errors in restarting of the system are avoided.
The system upgrading method provided by the embodiment of the invention can further comprise the following steps:
acquiring address information of a preset environment variable partition, reading partition information from a position in a storage space corresponding to the address information, and partitioning the storage space according to the partition information to obtain the environment variable partition and at least two partitions capable of being used as upgrading partitions; the environment variable partition is used for storing partition information, version information of firmware in a storage area where the system currently runs and a starting command used for starting the system from the corresponding partition;
correspondingly, after restarting the system from the current upgrade partition, the method may further include:
updating version information and a starting command in the environment variable partition;
the system may include a kernel and a file system, and the partition capable of being an upgrade partition may include two partitions capable of being upgrade partitions of the kernel and two partitions capable of being upgrade partitions of the file system.
The address information in the embodiment of the application may be a Flash physical address. The method and the device for processing the Env partition can preset the Flash physical address of the Env partition to be partitioned, and read partition information, version number and starting command from the Flash physical address corresponding to the Env partition to be partitioned; the starting command records whether the current system runs in a storage partition A (Kernel-A, Rootfs-A) or a partition B (Kernel-B, Rootfs-B) (Bootcmd parameters in the starting command record the current system running in the storage partition, for example, if the current system runs in the storage partition A, the current system also distinguishes the storage partition before the partition is not partitioned by recording the address form); accordingly, the other memory partition where the start command is not recorded is the "current upgrade partition". Thus, in practice, the physical addresses of 8 memory partitions are planned before being divided into 8 memory partitions.
The distribution situation shown in fig. 2 can be obtained by partitioning the storage space (which may be a storage space of SPI Nand Flash, and the total capacity of the storage space is 128 MB) according to the partition information, and the storage partitions include 8 storage partitions, namely an Env partition (an environment variable partition), an Uboot partition (a boot partition), a Conf partition (a configuration partition), a Data partition (a Data partition), and Kernel-A, Rootfs-A, Kernel-B, Rootfs-B; the Uboot partition is responsible for starting the whole system, and when the Uboot partition is started, the whole Kernel (Kernel) can be started according to a starting command in the Env partition, partition information is transmitted to the Kenrel to carry out system partitioning, and the whole Flash is divided into 8 partitions; the Env partition stores partition information and information necessary for starting the system, including version numbers, starting commands and the like; the Rootfs (file system) adopts a Squashfs read-only file system, so that the system file is prevented from being read and written randomly, and the system is prevented from being damaged; the Conf partition is mainly used for storing configuration files of the system, and after the system is started, each service module can read out configuration information from the system; the Data partition is used to store user files such as snap pictures, video clips, and the like.
In a specific implementation manner, for a case that a storage partition includes an Env partition, an Uboot partition, a Conf partition, a Data partition, and a Kernel-A, Rootfs-A, Kernel-B, Rootfs-B, a system upgrade method provided in an embodiment of the present application may include:
1) reading an upgrading instruction, and upgrading the Kernel region;
2) checking the upgrade package, reading CRC (cyclic redundancy check) sums from the header part of the Kernel mirror image in the upgrade package, simultaneously calculating the CRC sums of the data part, comparing the CRC sums with the CRC sums, and if the CRC sums are consistent, indicating that the check is correct;
3) reading the header part version number of the Kernel image of the upgrade package, comparing the version number with the version number in the Env partition (version parameter in the Env), and if the version numbers are not consistent, indicating that the upgrade is needed;
4) starting upgrading, erasing data in the current upgrading partition and writing mirror image data; it should be noted that, in the present invention, the "erase" action is an optimization scheme for ensuring that "dirty data" does not occur in the partition, for example, the system version of the past partition is V1.0, which occupies 1.8MB of memory, the system version that needs to be upgraded currently is V1.1, which occupies 1.5MB of memory, and if the erase is not performed, then 0.3MB of dirty data exists, which directly results in a failure of system upgrade. It is acknowledged that if the current system version needing to be upgraded is V1.2, the occupied memory size is 2MB, the whole memory area can be completely covered, and the system can not be erased.
5) Read-back verification, namely reading data from the current upgrade partition, calculating CRC (cyclic redundancy check) sums, comparing the CRC sums of the header parts of the Kernel images of the upgrade package, and if the CRC sums are consistent, indicating that the data is correctly written;
6) after the Kernel region is upgraded, calling the same program modules from the step 2) to the step 5) to upgrade the Rootfs;
7) and updating the partition information, the version number and the starting command in the Env partition.
Therefore, compared with the traditional single-partition upgrading method, the method for partitioning and upgrading the embedded equipment system separates the running partition from the upgrading partition, does not affect the normal work of the running partition in the upgrading process, does not need to close software, unload the partition and other operations, writes abnormal in the upgrading partition even if abnormal power failure occurs in the upgrading process, does not affect the work of the running partition after restarting, and greatly improves the upgrading efficiency and stability.
In addition, the invention optimizes the partition of the Flash storage space, divides the Flash storage space into eight storage partitions, presets the Flash physical address of the environment variable partition to be partitioned, and stores all parameters needing to be called, namely partition information, version number and starting command, in the corresponding physical address storage partition, and can quickly read the required parameters from the Flash physical address of the environment variable partition for upgrading when upgrading operation is carried out.
