After receiving the upgrading instruction, the embedded device suspends the operation of the current system according to the prestored system switching instruction, switches to the preconfigured upgrading system and enters a recovery mode. The upgrading system is an independent minimum system, has a simply configured kernel operating system and an independent root file system, and is independent from a main system in normal operation and not interfered mutually. And then establishing communication connection with the upper computer in a recovery mode according to a preset upgrading program in the upgrading system. The upgrading system which runs independently is configured for the embedded equipment in advance, the upgrading system is switched to run after an upgrading instruction is received, and the upgrading system is in communication connection with the upper computer according to a preset upgrading program to carry out image upgrading, so that the system upgrading and the normal running of the embedded equipment are independent from each other, and the interference of the image upgrading on the data which runs normally is avoided.
In some embodiments, establishing a communication connection with an upper computer according to a preset upgrade program in an upgrade system includes: the method comprises the steps of establishing physical connection with an upper computer through a pre-established Ethernet physical interface, and allocating an IP address for the upper computer to establish communication connection based on a dynamic host configuration protocol according to a preset upgrading program.
When the embedded device performs system upgrade in the recovery mode, there is no network interface capable of allocating an IP address, and therefore, the embedded device cannot be connected to other devices having network interfaces, and therefore, an ethernet physical interface can be created in advance for the embedded device for use in the recovery mode, and a preset upgrade program is added to the upgrade system, and the preset upgrade program is used for allocating an IP address to a device that establishes physical connection through the ethernet physical interface created in advance based on a dynamic host configuration protocol to complete establishment of communication connection. The ethernet physical Interface may be constructed by module collocation, for example, constructing a Gigabit Media Independent Interface RGMII (Reduced Gigabit Media Independent Interface), a Gigabit Media Serial Interface SGMII (Serial Media Independent Interface), an UxSGMII, a network Interface of a PCIE Interface, and the like. After the embedded device is switched to the upgrading system and enters a recovery mode, a network cable, such as an RJ45 network cable, is firstly utilized to be physically connected with an upper computer through a preset network port, then a local area network interface drive is loaded according to a preset upgrading program, the upper computer connected through the preset network port is allocated with an IP address based on a dynamic host configuration protocol, and a TCP connection is established between the upper computer and the embedded device, so that the communication connection between the upper computer and the embedded device is realized. The embedded equipment is characterized in that the upper computer is physically connected with the embedded equipment through a pre-established physical network port, and an IP address is allocated to the upper computer based on a dynamic host configuration protocol according to a preset upgrading program, so that the upper computer is in communication connection with the embedded equipment through a local area network, the embedded equipment can also obtain the mirror image data of a target version from the upper computer in an upgrading state, and the embedded equipment or the embedded system can be guaranteed to smoothly complete mirror image upgrading.
And 102, sending a mirror image data request of the partition to be updated to the upper computer, and receiving mirror image data sent by the upper computer.
Specifically, after determining a to-be-updated partition which needs to be subjected to image upgrading currently according to an image configuration file, the embedded device sends an image data request of the to-be-updated partition to the upper computer, then receives image data sent by the upper computer according to the image data request, and stores the received image data in a cache area or a specific storage area.
In some embodiments, the mirror image configuration file includes a standard length of mirror image data of the partition to be updated, and after receiving the mirror image data issued by the upper computer, the method further includes: detecting whether the actual length of the received mirror image data is consistent with the standard length of the mirror image data or not; and under the condition that the actual length of the received mirror image data is not matched with the standard length of the mirror image data, the mirror image data request of the current partition to be updated is sent to the upper computer again.
The mirror image configuration file not only can comprise the partition result of each mirror image file data area and the file name of the mirror image file corresponding to each mirror image file data area, but also can comprise the standard length of the mirror image data (the size of the mirror image file) in each mirror image file data area, and the embedded device determines the actual length of the received mirror image data after receiving the mirror image data of the current partition to be updated sent by the upper computer, and compares the actual length with the standard length of the mirror image data corresponding to the current partition to be updated carried in the mirror image configuration file. And under the condition that the actual length of the mirror image data is not consistent with the standard length of the mirror image data, judging that the obtained mirror image data has errors, re-sending a mirror image data request of the current partition to be updated to the upper computer, receiving the mirror image data re-sent by the upper computer until the actual length of the received mirror image data is consistent with the standard length, and storing the mirror image data. The standard length of the mirror image data is set in the configuration file, the received mirror image data is verified according to the standard length of the mirror image data carried in the configuration file after the mirror image data is obtained, and the mirror image data is requested to the upper computer again under the condition that the verification fails, so that the mirror image data is prevented from being missed, lost or mistransmitted.
In some embodiments, the mirror image configuration file includes a mirror image data check code of each partition to be updated, and after receiving the mirror image data issued by the upper computer, the method further includes: according to the mirror image data check code of the current partition to be updated, checking the mirror image data; and under the condition that the mirror image data does not pass the verification, re-sending a mirror image data request of the current partition to be updated to the upper computer.
The mirror image configuration file can also comprise mirror image data check codes corresponding to all mirror image file data areas serving as partitions to be updated, the embedded device reads the mirror image data check codes of the current partitions to be updated after receiving mirror image data issued by the upper computer, performs data check on the mirror image data according to a preset algorithm according to the mirror image data check codes of the current partitions to be updated, judges that the mirror image data has errors when the mirror image data does not pass the data check, re-sends a mirror image data request of the current partitions to be updated to the upper computer, performs data check on the re-received mirror image data until the received mirror image data can pass the data check, and then stores the mirror image data and performs subsequent mirror image upgrading steps. The file check code is set in the configuration file, the received mirror image data is checked according to the data check code carried in the configuration file after the mirror image data is obtained, and the mirror image data is requested to the upper computer again under the condition that the check is failed, so that the correctness and the accuracy of the obtained mirror image data are ensured, the mirror image updating accuracy is improved, and the error updating of the mirror image is avoided.
In some embodiments, the mirrored data check code includes: a longitudinal redundancy check LRC code, a cyclic redundancy check CRC code, or a message digest MD5 value.
The mirror image data check code can be set according to the adopted mirror image data check mode, and the mirror image data check mode can be selected according to the requirements of the actual scene, for example, when the mirror image data is required to be guaranteed not to be tampered, the MD5 value can be selected as the mirror image check code, and when the integrity and the correctness of the mirror image data are required to be guaranteed, the CRC code can be selected as the mirror image check code. By setting various optional file check codes, a proper file check code can be selected according to a specific application scene and actual requirements, and the adaptability of the system upgrading method to different scenes is improved.
It should be noted that, after receiving the mirror image data request of the embedded device, the upper computer may also perform data verification on the mirror image data to be sent in advance before sending the mirror image data, and directly report an error and upgrade the system of the terminal embedded device if the verification fails. In the process of sending the mirror image data, the sending length of the sent mirror image data can be recorded, and after the sending length reaches the marked length of the mirror image data, the sending request of the next partition of the mirror image data is started to wait.
And 103, under the condition that the partition to be updated is not the target partition, performing mirror image update on the partition to be updated according to the mirror image data, and sending a mirror image data request of the next partition to be updated to the upper computer after the update is completed.
Specifically, after completing data verification on received mirror image data, the embedded device needs to detect whether a current partition to be updated belongs to a target partition, where the target partition includes a data area constrained by a security trust mechanism and/or an original data area without a file system. The data areas in the embedded device include data areas having file systems, such as a root file system, a kernel boot image, a communication coprocessor running image, and the like, which are typically large and may be referred to as a main partition. Also included are raw data areas without file systems, such as IP address databases, executable file format databases, etc., and sensitive data areas subject to security trust mechanisms, which are typically small and may be referred to as small partitions. In order to ensure the efficiency of image updating, the small partition can be used as a target partition to perform centralized updating in the restart phase.
The embedded device detects whether the current partition to be updated belongs to a target partition, performs mirror image update on the partition to be updated according to mirror image data stored in a cache area or a specific storage address under the condition that the partition to be updated is not the target partition, deletes the stored mirror image data of the current partition to be updated after the update is completed, determines the next partition to be updated according to a mirror image configuration file, and sends a mirror image data request of the next partition to be updated to the upper computer until the mirror image data cache or the mirror image update of all the partitions to be updated is completed.
And step 104, caching the mirror image data under the condition that the partition to be updated is the target partition, performing mirror image update on the partition to be updated in the system restart stage according to a preset loading program, and sending a mirror image data request of the next partition to be updated to the upper computer after the cache is completed.
Specifically, after detecting whether the current partition to be updated belongs to the target partition, the embedded device detects whether a target partition cache list exists or not when the partition to be updated is not the target partition, creates a target partition cache list when the target partition cache list does not exist, then adds the partition identifier of the current partition to be updated in the target partition cache list, allocates a mirror image data cache address to the current partition to be updated, and stores the mirror image data of the current partition to be updated in the cache area. And under the condition that the target partition cache list exists, directly updating the target partition cache list, and storing the mirror image data of the current partition to be updated to the cache area according to the allocated mirror image cache address. And then, when the embedded device is restarted according to the preset loading program, accurately carrying out mirror image updating on each target partition to be updated according to the partition identification of the target partition in the system restarting stage.
In addition, after the embedded device completes the caching of the mirror image data of the current partition to be updated, the embedded device determines the next partition to be updated according to the mirror image configuration file, and sends a mirror image data request of the next partition to be updated to the upper computer until the caching or the updating of the mirror image data of all the partitions to be updated is completed.
In some embodiments, performing a mirror update on a partition to be updated in a restart phase according to a preset loader includes: after the mirror image updating of the partitions outside the target partition is finished, restarting the system according to a preset loading program; and in the process of restarting the system, reading the cached mirror image data through a loader, and updating the mirror image of each target partition.
The method comprises the steps that before image updating is carried out on a to-be-updated partition which belongs to a target partition by an embedded device in a restarting stage according to a preset loading program, whether image updating is finished on the to-be-updated partition which does not belong to the target partition or not needs to be detected according to the preset loading program, after image updating is finished on the to-be-updated partition which does not belong to the target partition, restarting is carried out on an upgrading system according to the preset loading program, in the restarting process of the upgrading system, a loader reads a target partition cache list from a cache region according to the preset upgrading program, reads image data of each target partition one by one according to partition identification in the target partition cache list and image data cache addresses of each partition, and directly configures images of each target partition according to the read image data, so that image updating of each target partition is finished. And the cached mirror image data can be deleted after the mirror image updating of all the target partitions is finished. By restarting the system after the mirror image update of the non-target partition is completed according to the preset loading program, the loader can directly perform the mirror image update on the data area constrained by the security trust mechanism and the original data area of the rootless file system according to the mirror image data in the cache area, thereby avoiding the need of changing the security trust mechanism of the system, simplifying the mirror image update process of the system and facilitating the burning of pre-installed firmware when a manufacturer manufactures products.
In some embodiments, after performing mirror image update on the partition to be updated according to the mirror image data and after caching the mirror image data, the method further includes: and sending a first response message to the upper computer, so that the upper computer updates the mirror image updating progress according to the first response message, and recovering the mirror image updating progress according to the mirror image updating progress under the condition that the mirror image updating progress is interrupted.
The embedded device acquires the mirror image data partition by partition in the process of upgrading the system, and directly utilizes the mirror image data to update the mirror image or cache the mirror image data according to whether the current partition to be updated belongs to the target partition. Therefore, after the mirror image update or the mirror image data cache of the partition to be updated is completed, the embedded device sends a first response message to the upper computer, and the first response message is used for prompting that the upper computer finishes sending the current mirror image data of the partition to be updated and is used for the upper computer to update the recorded mirror image update progress. For example, when the upper computer issues the mirror image data according to the partition sequence in the mirror image configuration file, the upper computer may create an update progress record, record the number of partitions that have completed issuing the mirror image data, where an initial value of the update progress is 0, add 1 after receiving a first response message, and detect whether to complete issuing the mirror image data of all the partitions according to the update progress record. And under the condition that the total number of the partitions in the mirror image configuration file is i, when the upper computer detects that the current updating progress record is i, judging that the mirror image data of all the partitions are completely issued, and terminating the transmission of the mirror image data.
The system upgrade of the embedded device is interrupted for various reasons, the system upgrade can be restored after the interruption and then is connected with the upper computer again, the upper computer firstly judges whether the version of the mirror image data requested by the embedded device is consistent with the version of the mirror image data issued before the interruption before the mirror image data is issued, and reports upgrade errors and interrupts the system upgrade of the embedded device under the condition that the versions of the mirror image data requested by the embedded device are inconsistent. And under the condition of consistent versions, detecting the stored updating progress records, and directly starting to resume the issuing of the mirror image data from the most front partition in the partitions which have not finished the issuing of the mirror image data when the system is interrupted in the upgrading process according to the current updating progress records until the issuing of the mirror image data of all the partitions is finished, and terminating the transmission of the mirror image data.
In addition, the first response message may further include a partition identifier of the current partition to be updated, so that the upper computer directly identifies the partition to which the image data issue is completed, and then randomly selects one partition from the partitions to which the image data issue is not completed to issue the image data.
