Detailed Description
In order that those skilled in the art will better understand the present invention, a technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
Reference herein to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic may be included in at least one implementation of the invention. In the description of the present invention, it should be understood that the terms "first," "second," "third," and "fourth," etc. in the description and claims of the invention and in the above-described figures are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
First, a firmware upgrade scenario is described by way of example. Referring to fig. 1, fig. 1 is a firmware upgrade scenario diagram according to an embodiment of the present application. As shown in fig. 1, the original file data of the firmware is stored in a preset storage area in the flash memory, when the firmware needs to be updated, an upgrade file corresponding to the firmware to be upgraded is obtained from the nonvolatile memory, and the upgrade file is written into the memory at one time, so that all the upgrade files are written into the flash memory at one time. Therefore, a large amount of memory space is occupied in the firmware upgrading process, and after power failure occurs, the memory needs to be rewritten to finish the upgrading of the firmware to be upgraded.
In order to solve the problems, the application provides a firmware upgrading method, in particular to a firmware upgrading method by acquiring an upgrading file corresponding to firmware to be upgraded; wherein the upgrade file comprises multi-frame data; backing up a first block of data of a first frame of data in the upgrade file in a memory; replacing first block data in the first frame data with null data to obtain first target frame data; storing the first target frame data in a flash memory; storing the rest frame data in the upgrade file into a flash memory; when the storage of the residual frame data is determined to be completed, storing the first block of data in the memory into the flash memory based on the target address; the target address is the storage address corresponding to the empty data in the flash memory. The memory space can be saved, the firmware upgrading process is simplified, the firmware upgrading file can be ensured to be completely written into the flash memory, the firmware upgrading fault tolerance rate is improved, and meanwhile, the integrity of the firmware upgrading is ensured; if power failure occurs in the upgrading process, aiming at the firmware to be upgraded which is not upgraded, the upgrading file does not need to be written into the flash memory again. For example, in the event of a power failure or occasional data transmission failure during an upgrade, when the bootloader does not recognize the first block of data of the firmware to be upgraded in the flash memory (i.e., abnormal data) when the power is turned back on or communication resumes, the bootloader may request the upgrade tool again to retransmit the data, for example, to retransmit the first frame of data, or to retransmit the remaining data. That is, the bootloader can identify whether an error occurs in the upgrading process, and as long as the upgrading tool is still online, the firmware updating operation (or the remaining data is continuously transmitted) can be performed again, so that no extra flash memory or memory space is needed to backup the whole upgraded firmware.
The following describes a specific embodiment of a firmware upgrading method of the present application, and fig. 2 is a schematic flow chart of a firmware upgrading method provided by the embodiment of the present application; the present specification provides method operational steps as an example or a flowchart, but may include more or fewer operational steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution. When implemented in a real system or server product, the methods illustrated in the embodiments or figures may be performed sequentially or in parallel (e.g., in a parallel processor or multithreaded environment). As shown in fig. 2, the method may include:
s202: acquiring an upgrade file corresponding to firmware to be upgraded; the upgrade file comprises multi-frame data.
Specifically, the upgrade tool obtains the upgrade file, and stores the upgrade file in a nonvolatile memory of the upgrade tool. The bootloader program acquires the upgrade file from the upgrade tool frame by frame.
S204: backing up a first block of data of a first frame of data in the upgrade file in a memory; and replacing the first block data in the first frame data with null data to obtain first target frame data.
In some alternative embodiments, the first block of data may be the top of stack data of the upgrade file or entry address data of the firmware to be upgraded. The top of stack data and entry address data may be used to identify the firmware to be upgraded. Wherein the entry address data is used to support the running of the program.
To determine that the upgrade file is secure, verification of the correctness of the upgrade file is typically required. In some optional embodiments, before performing the step of backing up the first block of data of the first frame of data in the upgrade file in the memory, the method further includes:
Checking the first frame data to obtain a first frame check value;
And under the condition that the first frame check value meets the preset first frame check value, executing the step of backing up the first block data of the first frame data in the upgrade file in the memory.
In this embodiment, the preset first frame check value may be a preset first frame check value generated according to a fixed segment character of the first frame data in the upgrade file after the upgrade file is developed, for example, the preset first frame check value is generated according to a character at the end of the first frame data; and under the condition that the first frame check value is consistent with the preset first frame check value, determining that the first frame data is safe and correct.
In some alternative embodiments, each frame of data of the upgrade file in the subsequent step S208 may be checked to ensure that each frame of data written is correct.
S206: and storing the first target frame data in a flash memory.
In order to occupy as little memory space as possible during the firmware upgrade, in some optional embodiments, the first block of data is used to identify the upgrade file;
Before backing up the first block of data of the first frame of data in the upgrade file in the memory, the method further includes:
determining a minimum writable unit of the flash memory;
based on the number of bytes of the minimum writable unit, the number of bytes of the first block of data is determined.
The first block of data in this embodiment has the least bytes under the condition that the upgrade file can be identified and the flash memory can be written, so that the space occupied by the memory is reduced as much as possible in the firmware upgrade process.
S208: and storing the rest frame data in the upgrade file into the flash memory.
Typically, the flash memory stores original file data of firmware to be upgraded before upgrading, and in order to write an upgrade file, in some alternative embodiments, the storing the first target frame data in the flash memory includes:
determining a firmware storage address of the firmware to be upgraded in the flash memory;
Erasing the data stored in the firmware storage address under the condition that the firmware storage address stores the data;
Storing the first target frame data in the firmware memory address in the flash memory; the firmware memory address includes the target address.
In this embodiment, when the first frame data is written, all the multiple storage data corresponding to the firmware to be upgraded in the flash memory are deleted, so as to avoid confusion between the original data and the upgrade data, that is, ensure that the first block data of the firmware to be upgraded in the flash memory is the data in the stored upgrade file when the first block data of the firmware to be upgraded is empty, and then complete the upgrade of the firmware to be upgraded when the non-empty first block data is written into the flash memory.
S210: when the storage of the residual frame data is determined to be completed, storing the first block of data in the memory into the flash memory based on a target address; and the target address is a storage address corresponding to the empty data in the flash memory.
To further reduce the amount of memory space consumed during firmware upgrades. In some optional embodiments, storing the remaining frame data in the upgrade file in the flash memory includes:
And storing the rest frame data in the upgrade file into the flash memory frame by frame.
According to the embodiment, in the firmware upgrading process, the memory stores data of not more than one frame into the flash memory each time, so that the storage space of the memory is saved.
In order to determine that the first block of data in the memory belongs to the upgrade file, and ensure the correctness of the upgrade file written into the flash memory, in some alternative embodiments, before performing the step of storing the first block of data in the memory into the flash memory based on the target address in step S210, the method further includes:
acquiring candidate block data from the memory; the candidate block data is any block data in the multiple blocks of data in the memory;
Checking whether the candidate block data is the first block data of the upgrade file;
And under the condition that the candidate block data is determined to be the first block data of the upgrade file, executing the step of storing the first block data in the memory into the flash memory based on a target address.
Specifically, in the step S204, when the first block of data is backed up in the memory, the target block check value may be generated based on the first block of data; and generating a first check value based on the candidate block data in the flash memory, determining whether the first check value is correct based on the target block check value, and determining the candidate block data as the first block data of the upgrade file under the condition that the first check value is correct.
In this embodiment, the first block data corresponding to the upgrade file is determined by checking the first block data, so that the first block data is written into the target address in the firmware storage address corresponding to the firmware to be upgraded in the flash memory, and the integrity of firmware upgrade is ensured.
To verify that the upgrade was successful. In some optional embodiments, after storing the first block of data in the memory in the flash memory based on a target address, the method further includes:
identifying the first block of data in the flash memory;
and under the condition that the first block data is identified, determining that the firmware to be upgraded is successfully upgraded.
By the embodiment, whether the first block of data in the flash memory is valid or not can be verified, so that whether the firmware to be upgraded is successfully upgraded or not is verified, and the integrity of firmware upgrade is ensured.
The application provides a firmware upgrading process based on bootloader programs. Fig. 3 is a schematic flow chart of firmware upgrade based on bootloader program according to an embodiment of the present application, and specific steps are as follows:
S301: and (5) powering up.
In some alternative embodiments, the embedded system is powered on and the upgrade tool determines the update time of the upgrade file in the nonvolatile memory.
In some alternative embodiments, the embedded system may be powered on, and the upgrade tool may send upgrade file data in the nonvolatile memory directly to the bootloader program.
Specifically, the execution subject of the following steps S302 to S316 may be bootloader program.
S302: and judging whether an upgrade command is received. Specifically, the bootloader program determines whether an upgrade command for firmware sent by the upgrade tool is received.
If an upgrade command is received, step S303 is performed to obtain and check whether the current frame data is correct; if the upgrade order is not received, the step S304 is performed, and whether the time waiting for the upgrade order is overtime is judged.
S303: and acquiring and checking whether the current frame data is correct.
For example, when an upgrade command is sent to the bootloader program by the upgrade tool, the first frame data in the upgrade file is sent to the bootloader program at the same time, and at this time, the first frame data is current frame data.
Specifically, a current frame check value is generated based on the obtained fixed segment characters of the current frame data; and under the condition that the current frame check value is consistent with the preset current check value, determining that the current frame data is safe and correct. For example, the first frame check value is generated based on the acquired fixed segment characters of the first frame data; and under the condition that the first frame check value is consistent with the preset first frame check value, determining that the first frame data is safe and correct.
If the upgrade file is correct, the process advances to step S306, where it is determined whether the acquired current frame data is the first frame data. In the case that the upgrade file is incorrect, step S305, a request for acquiring the upgrade file frame by frame is sent to re-acquire the current frame data of the upgrade file.
S304: judging whether the time is overtime.
Specifically, if the time of the judgment step in step S302 exceeds a certain time, a timeout is determined. If the time-out is over, the process proceeds to step S315, where it is determined whether the first block of data in the flash memory is valid, i.e., whether the firmware has completed the upgrade. If the time-out is not exceeded, the step S302 is re-entered, and it is determined whether an upgrade command is received.
S305: and sending a request for acquiring the upgrade file frame by frame.
Specifically, the upgrade file includes multi-frame data. The bootloader program acquires an upgrade file from the upgrade tool frame by frame; the data in the upgrade file is temporarily stored in the memory frame by frame so as to write the data in each frame into the flash memory, thereby avoiding the situation that all the upgrade file contents are acquired at one time and stored in the memory, occupying the memory space and further affecting the running speed of the embedded system.
S306: it is determined whether the acquired current frame data is first frame data.
When the extracted current frame data is the first frame data, the process proceeds to step S307 to backup the first block data in the first frame data in the memory.
S307: backing up a first block of data in the first frame of data in a memory; and checking the first block data to obtain a target block check value.
Specifically, the target block check value is used to identify the first block of data in the flash memory in the subsequent step S312.
S308: and replacing the first block data in the first frame data with null data to obtain first target frame data.
In this embodiment, the first block data is replaced by the null data to ensure that the first block data for identifying the upgrade file is finally written into the flash memory (i.e., step S315).
S309: and erasing the data stored in the firmware storage address, and storing the current frame data in the firmware storage address in the flash memory.
Specifically, the flash memory includes a storage area for storing data of each firmware file, and the processor of the embedded system reads the data of each firmware file, that is, runs each firmware.
S310: it is determined whether the current frame data is the last frame data.
Specifically, it is determined whether the current frame data acquired in step S303 is the last frame data, and if the current frame data is the last frame data, step S311 is entered to acquire and check the first block data backed up in the memory. If the current frame data is not the last frame data, the process proceeds to step S305 to continue to extract the next frame data of the upgrade file.
S311: and acquiring and checking the backed-up first block of data.
Specifically, a first block of data is obtained from the flash memory, and a first check value is generated.
S312: and judging whether the check of the first block of data is passed.
Specifically, the target block check data is used to determine whether the first check value in step S311 is correct. If the first check value is incorrect, the check is not passed, and step S313 is performed to determine that the upgrade has failed. If the first check value is correct, the check is passed, and the process proceeds to step S314, where the backed-up first block data is written into the flash memory.
S313: the upgrade failed. I.e. the upgrade of the firmware to be upgraded fails.
In some alternative embodiments, a re-upgrade may be performed. Specifically, after determining that the upgrade has failed in step S313, the process may proceed to step S302, where the bootloader program continues to wait for the upgrade command.
S314: and writing the backed-up first block of data into the flash memory.
Specifically, the first block of data is written into the target address corresponding to the empty data in the flash memory, so that a complete upgrade file is written into the flash memory, and the success of upgrading the firmware to be upgraded is ensured.
S315: and judging whether the first block of data in the flash memory is valid or not.
Specifically, whether the first block of data corresponding to the target address in the flash memory is empty is judged. And when the first block data is in a non-empty state, determining that the first block data is valid. In the case where it is determined that the first block data is valid, the flow proceeds to step S316, where the firmware is run. In the case where it is determined that the first block data is invalid, the flow advances to step S302, and the reception of the upgrade command is continued.
S316: and running firmware.
Specifically, the embedded system runs the firmware, that is, runs the data stored in the firmware storage address corresponding to the firmware in the flash memory.
In the above embodiment, the firmware is upgraded based on the bootloader program, so that the upgrade file of the firmware can be ensured to be completely written into the flash memory; and improves the fault tolerance of firmware upgrade, for example, in case of upgrade error, such as power-off, the upgrade can be continuously completed based on the steps shown in fig. 3 after power-up. Because the upgrade file is written into the flash memory frame by frame, the space of the memory is saved.
