Example 1
Embodiment 1 of the present invention discloses a firmware upgrading method for an embedded device, as shown in fig. 1, including the following steps:
s101, acquiring a firmware compression file; the firmware compression file is obtained by compressing the firmware;
specifically, the firmware is downloaded from an official website of firmware update through a terminal such as a PC (Personal Computer) device or a mobile phone, for example, the firmware with the newest version may be downloaded, or the firmware with another version may be downloaded.
The specific compression software can be selected from compression software such as WINRAR, 7ZIP, etc. The format of the corresponding firmware compression file may also be one of a plurality of compression formats.
Step S102, transmitting the firmware compressed file to a preset first storage area of the embedded equipment;
specifically, 3 regions are divided in advance on the chip storage space of the embedded device: OTA BIN region, APP BIN region, NEW APP BIN region.
The OTA BIN area is used for storing an instruction or parameter OTA BIN for OTA transmission so as to ensure that the embedded equipment can smoothly acquire the firmware;
here, the preset first storage area corresponds to an area storing the NEW APP BIN, and is used for storing an area of firmware to be updated, for example, in a general case, for example, to store firmware with a latest version, and here, to store a firmware compressed file, a size of a required space can be effectively reduced, for example, a size of an original firmware is 1152KB, and after compression, for example, a compression ratio is about 0.6, in this case, for example, an obtained firmware compressed file size is 684KB (in a compression process, due to a difference in format of compressed files, an actual compression ratio generally has a certain difference from an expected compression ratio, but in a case of no difference, the actual compression ratio is within an allowable range);
and the subsequent preset second memory area corresponds to the area for storing the APP BIN, so that the APP BIN is the currently operated firmware.
As shown in table 1, the distribution and occupied space size of the memory area of the chip that does not adopt the compression algorithm are:
TABLE 1
| Serial number | Firmware name | Firmware size |
| 1 | OTA BIN | 128(KB) |
| 2 | APP BIN | 1152(KB) |
| 3 | NEW APP BIN | 684(KB) |
The sum of the OTA BIN, the APP BIN and the NEW APP BIN is 2432K bytes which are larger than 2M bytes (2048K bytes), and if the size of a chip memory is only 2M bytes and 4Mbytes 2, only 4M bytes can be selected.
If the scheme is adopted, the distribution and occupied space size of the chip storage area are shown in the following table 2:
TABLE 2
| Serial number | Firmware name | Firmware size |
| 1 | OTA BIN | 128(KB) |
| 2 | APP BIN | 1152(KB) |
| 3 | NEW APP BIN | 684(KB) |
It can be seen that OTA BIN, after the three BINs of APP BIN and NEW APP BIN are added, 1964Kbytes are obtained, and the 2M bytes (2048K bytes) can be selected. Therefore, the cost of purchasing the memory chip can be reduced.
Specifically, the firmware compressed file is obtained by compressing the firmware into a specified compression format, and the name of the firmware compressed file contains a specified identifier; for example, a firmware compression file is a file named "upgrade 0001.7 z", where 7z is a specified compression format and "upgrade" is a specified identification; the specified compression format and the specified identifier are only taken as examples, and the specific specified compression format and the specified identifier may be customized according to actual needs, and are not limited to the above examples.
As shown in fig. 2, the step S101 of "transferring the firmware compression file to the preset first storage area of the embedded device" includes:
if the OTA instruction is acquired, controlling the embedded equipment to enter an OTA mode;
controlling the embedded equipment to perform data receiving operation in the OTA mode;
judging whether the received data is a compressed packet or not; specifically, if the packet is not a compressed packet, the subsequent processing of the scheme is not performed;
if so, judging whether the compression format of the compression packet is the specified compression format; specifically, if the compression format is not the specified compression format, for example, the compression format is not the 7z format, the subsequent processing of the scheme is not performed;
if the judgment result is yes, judging whether the name of the data comprises the specified identification; for example, if the name does not protect the designated identifier of "upgrade", the subsequent processing of the scheme is not performed.
If the judgment result is yes, the received data is determined to be a firmware compressed file and is stored in a preset first storage area.
Specifically, after receiving the OAT instruction, the APP BIN controls the embedded device to enter an OTA mode to receive a firmware compression file in the OTA mode, and stores the firmware compression file in a preset first storage area for subsequent firmware upgrade.
In addition, since it is necessary to control the time of firmware upgrade, the method further includes:
and if the time for receiving the firmware compressed file exceeds the preset time or the time for interruption during receiving the firmware compressed file exceeds the specified time or the verification fails, exiting the OTA mode.
Specifically, the time for receiving the firmware compressed file may include a receiving time when the connection is not interrupted, and if the interruption occurs while receiving the firmware compressed packet and the interruption time exceeds a certain time, the OTA mode is also exited.
In a specific embodiment, the "transferring the firmware compression file to the preset first storage area of the embedded device" includes: if the embedded equipment supports the direct connection OTA server, the firmware compression file is stored in the OTA server, and the firmware compression file is acquired from the OTA server through the embedded equipment and is stored in a preset first storage area; if the embedded equipment does not support the direct connection OTA server, the firmware compression file is stored in the OTA server, the firmware compression file is acquired from the OTA server through the third-party equipment, and the firmware compression file is acquired from the third-party equipment through the embedded equipment and stored in a preset first storage area; the third-party equipment is a terminal supporting direct connection with the embedded equipment.
Specifically, firstly, a firmware compression file is placed on an OTA server, and an embedded device downloads APP BIN through a certain way;
if the equipment supports direct connection with the OTA server, the embedded equipment is directly connected with the OTA server for downloading; if the embedded equipment does not support the direct connection with the OTA server, the embedded equipment is transferred by third-party equipment, generally, a mobile phone APP is firstly downloaded from the OTA server, then the mobile phone APP is connected with the equipment through Bluetooth, and then the embedded equipment is downloaded from the mobile phone; and finally, storing the firmware compression file downloaded by the embedded equipment into a preset first storage area, namely a NEW APP BIN area.
Step S103, verifying the firmware compression file in the preset first storage area;
specifically, after the firmware compressed file is stored in the preset first storage area, verification is required, and the specific verification may be hash value verification, in a specific application process, after the firmware compressed file is obtained in step S101, hash value calculation is performed on the firmware compressed file to obtain a first hash value of the current firmware compressed file, and then the firmware compressed file stored in the preset first storage area is subjected to hash value calculation again to obtain a second hash value, where the verification is to compare whether the first hash value is the same as the second hash value, and if the first hash value is the same as the second hash value, it is indicated that the firmware compressed file stored in the preset first storage area is the same as the firmware compressed file in step S101, and the file is not tampered or damaged in the transmission process; if the first hash value is different from the second hash value, it indicates that the firmware compressed file stored in the preset first storage area is inconsistent with the firmware compressed file in step S101, and the present scheme needs to be exited, that is, the firmware upgrade needs to be exited.
Step S104, if the verification is passed, decompressing the firmware compressed file to a preset second storage area of the embedded device;
in this step, the firmware compression file is decompressed to a preset second storage area of the embedded device, and the firmware corresponding to the firmware compression file replaces the firmware that was previously run in the preset second storage area (for example, an APP BIN area).
And step S105, restarting the embedded equipment to enable the embedded equipment to execute the decompressed firmware, and finishing firmware upgrading.
Specifically, before restarting the embedded device, the method further includes:
carrying out integrity detection on the firmware decompressed into a preset second storage area of the embedded equipment;
and if the integrity detection is passed, executing the step of restarting the embedded equipment.
Specifically, in consideration that there is a small probability that an error may occur during decompression, which results in incomplete firmware obtained after decompression, in this case, integrity check may be performed between step S104 and step S105, so as to ensure that the file decompressed into the preset second storage area is completely executable.
The specific decompression can be the same software as the compression, or different software, as long as the normal decompression can be performed.
If the integrity detection is not passed, executing a step of decompressing the firmware compressed file to a preset second storage area of the embedded device.
Specifically, if the integrity check fails, it indicates that the firmware compressed file has no problem due to the previous check, and in this case, it indicates that the decompression has a problem, the firmware compressed file is decompressed to the preset second storage area again to cover the original firmware.
In a specific embodiment, the method further comprises: recording the number of times that the integrity detection fails; and if the times reach the preset value within the preset time, executing a preset warning process.
Specifically, if the number of times that the integrity detection fails exceeds a certain value, it indicates that there is a problem with decompression, and in this case, an alert process is performed, for example, a maintenance engineer may be notified to perform field processing, so as to solve the problem in time and avoid waiting for a delay time.
