The application provides a microcontroller OTA method based on an Internet of things platform, which can be divided into three functional blocks, namely microcontroller upgrade scheme selection, control of the upgrade data (upgrade firmware) of the Internet of things platform and control of the OTA upgrade flow of the microcontroller.
In particular, reference is made to a schematic structural diagram of a microcontroller as shown in fig. 1. The microcontroller online upgrade in the embodiment of the application can be realized based on the Internet of things platform, namely online upgrade is required to be performed by selecting the Internet of things module accessed to the Internet of things platform as a bridge for data interaction.
As shown in fig. 1A, the microcontroller 100 includes an internet of things module 110, an external memory chip 120, a microcontroller chip 130, and other input function modules 140 and other output function modules 150. The internet of things module 110 may be a WiFi module, a bluetooth module, a GPRS module, etc., and may take into account the cost of the product in the initial stage of the design scheme, including selecting a micro controller chip with a large capacity, a high price, or a small capacity and a low price. The large-capacity micro controller chip is selected to be upgraded in a mode of internally dividing a storage area, namely an upgrade data storage area is divided in the micro controller internal storage area and used for storing upgrade data; the small-capacity micro controller chip is selected to be upgraded by adopting the external memory chip 120, namely, the external memory chip 120 can be regarded as the upgrade data storage area to store upgrade data.

The method can select, correct and the like when the microcontroller is upgraded, ensure the adaptation of the microcontroller and the upgrade data, and reduce the error occurrence rate.
The upgrade operation setting can further control the type of upgrade operation, the prompt of a user and the range of upgrade equipment. Optionally, referring to an upgrade operation setting page schematic of a microcontroller as shown in fig. 1C, the content of the upgrade operation setting may specifically include:
The release mode is as follows: the release mode can be divided into two kinds of equipment upgrade establishment and whole equipment upgrade;

Reference may be made to a flow chart of a method for online upgrade of a microcontroller as shown in fig. 2. The method may include:
201. and receiving upgrade data, and storing the upgrade data in the upgrade data storage area.
The execution main body of the embodiment of the application is a microcontroller, which comprises an internet of things module, and can be a WiFi module, a Bluetooth module, a GPRS module and the like, wherein the microcontroller can be used for online upgrading by taking the internet of things module accessed to the internet of things platform as a bridge for data interaction.
The upgrade data are microcontroller upgrade data which can be downloaded from a platform server in a wireless transmission mode, and in the embodiment of the application, in order to improve the fault tolerance in the upgrade process, the storage space of the microcontroller is divided into 4 areas: a code starting area, a code application area, an upgrade data storage area and a flag information storage area.
The upgrade data storage area is used for storing upgrade data, the mark information storage area is used for storing an identifier indicating an upgrade state in upgrade processing, the code starting area is used for storing and running a starting code of the microcontroller, and the starting code is used for initializing system parameters of the microcontroller; the code application area is used for storing and running application codes of the microcontroller.
And the acquired upgrade data is firstly stored in an upgrade data storage area.
In an alternative embodiment, the upgrade information of the upgrade data may be received first, where the upgrade information includes a firmware type, a firmware serial identifier, and version information;
Checking the firmware type, the firmware series identifier and the version information, and judging whether the upgrade data is suitable for the microcontroller;
If yes, storing the upgrade information; and emptying the upgrade data storage area and starting to receive the upgrade data.
The upgrade information processing of the microcontroller mainly aims at checking upgrade information and storing firmware key information. The information to be checked may include firmware type, firmware serial identifier, internal version, etc., and by means of the firmware type and firmware serial identifier, it may be determined whether the received upgrade request meets the requirements, for example, in the above-mentioned products sent to the southern city and northern city, the upgrade data of the microprocessor cannot be used universally. The microcontroller stores a preset firmware type, after receiving the upgrade information, the microcontroller can verify whether the firmware type in the upgrade information is consistent with the preset firmware type, and upgrade can be executed under the condition of consistency; the internal version information is managed by the internal logic of the microcontroller software, whether the software version is supported to be freely switched or can only be upgraded from low to high is judged, for example, the control rule of the version information of the microcontroller is preset, the control rule of the version information of the microcontroller is set to be only upgraded from low to high, whether the level in the version information of the upgrade data is higher than the level in the current version information is required to be verified during each upgrade, and if the level is higher than the level in the current version information, the upgrade is carried out. This information, if violated with the software logic of the microcontroller itself, may directly cancel the upgrade.
Further optionally, before the verifying the firmware type, the firmware serial identifier and the version information, the method further includes:
acquiring the storage space parameters of the microcontroller and the total number of bytes of firmware of the upgrade data;
judging whether the memory of the microcontroller supports the storage of the upgrade data according to the storage space parameters and the total number of bytes of the firmware;
If yes, triggering the step of checking the firmware type, the firmware serial identifier and the version information.
Specifically, the firmware key information to be stored may include the total number of bytes of the firmware and the accumulated checksum. Wherein the total number of bytes of firmware can be used to compare whether the existing memory space of the microcontroller supports downloading the upgrade data, and if the remaining memory size is exceeded, the upgrade can be canceled. When the server sends the upgrade data, the data are accumulated to obtain a data sum, the sum is negated to obtain the accumulated checksum, and the microcontroller can check whether the data are completely received according to the received data and the accumulated checksum.
Optionally, after the receiving the upgrade data, the method further includes:
Under the condition that the data frame sequence of the upgrade data is correct, acquiring an initial check value of the upgrade data;
after the upgrade data is stored in the upgrade data storage area, acquiring a target check value of the data of the upgrade data storage area;
comparing whether the target check value is consistent with the initial check value;
and if the update data are consistent, triggering the step of carrying out accumulation check on the update data.
Data verification is a verification operation performed to ensure the integrity of data. The method comprises the steps that a specified algorithm is used for calculating a check value of original data, a receiver calculates the check value once by using the same algorithm, and if the check values obtained by the two calculation are the same, the data is complete.
The checksum (checksum) to which embodiments of the present application relate is a checksum for verifying a set of data items at a destination, which is typically in the form of a hexadecimal representation of a number system, in the fields of data processing and data communications. Are commonly used to ensure data integrity and accuracy in communications. In the embodiment of the application, the check value can be calculated by performing cyclic redundancy check (Cyclic redundancy check, CRC) on the data so as to compare whether the check values (the initial check value and the target check value) before and after writing the updated data storage area are consistent or not, and whether the data before and after writing are consistent or not is compared, if the check sums are consistent, the data writing is correct, if the check sums are inconsistent, the data writing is incomplete, the failure of updating of the server can be responded, and the updating is cancelled.
202. And under the condition that the whole upgrade data is received, performing accumulation check on the upgrade data.
Wherein the above accumulation check is accumulation sum check CheckSum) algorithm. It is possible to verify whether the data reception is complete or not by performing an accumulation check on the received data.
Specifically, when the server sends the upgrade data, the data are accumulated to obtain a data sum, and the sum is negated to obtain an accumulated checksum. The upgrade data is then sent to the microcontroller, where the starting frame content of the upgrade data carries the accumulated checksum. The microcontroller may accumulate the received data (including the checksum) and then increment by 1, indicating that no transmission errors have occurred in the data if a 0 is obtained. Wherein the server and the microcontroller are used for keeping the type of the accumulated result consistent.
Whether the data frame sequence of the upgrade data is correct can be detected firstly, if not, the upgrade failure of the server can be responded, and the upgrade is canceled; if the data is correct, whether the checksum of the upgrade data is consistent before and after the data is received is compared, if the checksum is consistent, the data is complete, and if the checksum is inconsistent, the data is incomplete, and the upgrade can be canceled.
In an alternative embodiment, in case of timeout of receiving the upgrade data, the upgrade data is requested again to be received from the server;
And when the number of times of receiving the upgrade data reaches a first time threshold value, canceling receiving the upgrade data and sending download failure information to the server.
The first time count threshold may be preset, and the reception may be repeated when the reception of the upgrade data is timed out, the first time count threshold is used to limit the number of repeated requests, and when the number of times of reception timeout is detected to reach the first time count threshold, the reception of the upgrade data may be canceled, and the download failure information may be transmitted to the server.
203. And writing an upgrade starting identifier into the mark information storage area under the condition that the accumulation check passes.
In one embodiment, when the flag information storage area detects the upgrade start flag, the download completion information may be sent to a server, where the download completion information is used to instruct the microcontroller to complete downloading the upgrade data.
The foregoing description may further set a release manner, an upgrade manner and an upgrade prompt for the microcontroller upgrade data released by the platform server when the platform is released, and after the upgrade data is downloaded, the corresponding upgrade process may be performed according to the setting information in the upgrade data, for example, the upgrade process is set to be a common upgrade, the microcontroller may prompt the user to upgrade after the upgrade data is moved to the code application area for storage, and the upgrade prompt is the preset prompt content after the user agrees.
204. And starting software reset, entering the code starting area, and moving the upgrade data of the upgrade data storage area to the code application area for storage.
Specifically, after the data downloading stage is finished, the method can reset and enter the code starting area, judges whether the mark information storage area has an upgrading starting mark, if not, terminates the program operation, and if yes, starts the data carrying, namely, moves the upgrading data from the upgrading data storage area to the code application area for storage.
205. And after the upgrade data is successfully moved, modifying the upgrade starting identification of the mark information storage area into a success identification so as to indicate that the upgrade of the microcontroller is successful.
In an alternative embodiment, the identification information in the above-mentioned identification information storage area is read; the upgrade result is determined to be upgrade success under the condition that the success identification is read, and the upgrade result is determined to be upgrade failure under the condition that the failure identification is read;
transmitting the upgrade result to the server; and clearing the data of the mark information storage area.
Optionally, when a storage abnormality occurs in the upgrade data, triggering the step of moving the upgrade data in the upgrade data storage area to the code application area for storage again;
When the number of times of occurrence of storage abnormality of the upgrade data reaches a second number threshold, the upgrade processing is stopped, it is determined that the movement of the upgrade data fails, an upgrade start identification of the flag information storage area is modified to a failure identification, and upgrade failure information is transmitted to the server.
Similarly to the first time threshold, a second time threshold may be preset, an abnormality occurs when the upgrade data is moved, a movement operation may be repeatedly requested (for example, the second threshold is 5, 5 movement operations may be repeatedly attempted), and when it is detected that the number of times of occurrence of the storage abnormality of the upgrade data reaches the second time threshold, the attempt to move the data may be canceled, the program operation may be terminated, and the upgrade may fail.
Under the condition that the successful identification is read in the mark information storage area, the success of the upgrading can be determined, and the upgrading is fed back to the server to finish the upgrading. After the processing is completed, the flag information storage area needs to be emptied, and then the next upgrading action uses the area.
The traditional microcontroller upgrading mode is that a chip burner provided by a microcontroller chip manufacturer is used for updating a program, the upgrading mode of the microcontroller can be used in a debugging stage of a product, the product is not provided with a shell, but the product is difficult to operate after being formally marketed in batches, the whole machine needs to be split for upgrading the product in the mode, the product can be upgraded only by connecting the burner through a connecting wire after a control panel is exposed, the mode is obviously unreasonable to products from a factory, certain permanent damage is caused after the whole machine product is split, the turnover cost related to the product returning is not the cost of the manufacturer, and the microcontroller OTA method based on the Internet of things platform needs to be used under the conditions of not damaging the products and reducing the turnover cost. The method in the embodiment of the application is a stable micro-controller OTA method based on the platform of the Internet of things, which not only can damage products, but also can strictly control the safety and version information of micro-controller chip software.
In order to more clearly illustrate the process flow of upgrading the microcontroller in the embodiment of the present application, reference may be made to fig. 3, and fig. 3 is a schematic diagram of an upgrade flow of the microcontroller according to the embodiment of the present application. In the embodiment of the application, in order not to influence the normal functions of the microcontroller in the upgrading process, the functions are normally operated in the process of upgrading firmware downloading, namely, upgrading data is firstly downloaded to an upgrading data storage area and then software is upgraded, so that normal function use is not influenced even if the upgrading fails, the normal function is directly replaced after the upgrading starts in other schemes, and all functions of a product are lost once the product is in a midway upgrading state.
As shown in fig. 3, wherein the start frame data of the upgrade data includes the aforementioned upgrade information, i.e., the start frame data content may include a firmware type, a firmware series, a firmware total byte, an accumulated checksum, and version information.
Verifying the firmware type, the firmware serial identification and the version information; if the verification is not passed, the updating of the response server fails, and the updating is canceled; if the verification is passed, storing the initial frame data content (firmware total bytes, accumulated checksum);
after the initial frame data is stored, the upgrade data storage area can be erased, and the upgrade data is prepared to be cached; the response server starts to receive the data;
judging whether the data reception is overtime (for example, the process is 3 seconds, judging overtime, 10 continuous operations); under the condition of overtime of multiple times of receiving, the server upgrade failure can be responded, and the upgrade is canceled; if the received data has not timed out,
Detecting whether the data frame sequence is correct;
if the data frame sequence is incorrect, the response server fails to upgrade, and the upgrade is canceled; if the data is correct, performing CRC16 calculation to obtain a check value (for performing data comparison before and after writing);
writing the received data into an OTA data storage area;
Reading data written into the upgrade data storage area, calculating a CRC16 target check value, and comparing whether the initial check value before and after writing is identical with the target check value; if the answer is different, the upgrade of the response server fails, and the upgrade is canceled; if the same, the upgrade data can be accumulated and calculated (so that the accumulated check comparison is carried out after the complete receiving of the data);
Judging whether all the data are received, if not, requesting the server to send the next frame of data; if the data is received, performing accumulation check comparison;
If the accumulated check fails, the updating of the response server fails, and the updating is canceled; if the accumulation check is passed, writing an OTA-START mark in an OTA related FLAG information sector (mark information storage area); the answer server downloads and ends; finally, the software is reset to enter a code starting area to prepare for starting the upgrade data carrying;
After the software is reset and restarted, judging whether an OTA-START mark exists in the mark information storage area, and if not, not carrying out data carrying processing; carrying out data carrying if the data is available; carry the data of the upgrade data storage area to APP area (code application area);
Detecting whether the handling is successful (if not, repeating the operation for 5 times); writing an OTA-SUCCESS mark into the mark information storage area to enter an APP area under the condition that the carrying for many times is unsuccessful;
Judging whether the connection server is overtime; if the time is over, if the time is not over, judging whether an OTA-SUCCESS mark exists or not; if the chip is not in error, the program is stopped to run, and the upgrading is failed; if yes, the answer server is successfully upgraded, and the upgrade is ended.
In general, the upgrade data interaction adopts a response mode, the platform sends data, and the microcontroller responds after receiving the data, if the data is not received by the intermediate microcontroller or the received data is abnormal, the corresponding data can be requested to be retransmitted, so that the situation that the data is missing and wrong is avoided.
After the data handling is completed, the mark information storage area is changed into an OTA-SUSESS mark, and if the handling FAILs, the OTA-FAIL mark is changed into the OTA-SUSESS mark, generally, the data handling cannot FAIL, and once the handling FAILs, the storage area of the microcontroller is irreparably damaged, and in this case, the microcontroller chip can only be replaced.
